• Problem with files consists of spaces and single quotes?

  - by Vijay

  I'using the following code to create thumbnails using ffmpeg but it was working fine for the files which have no spaces or any quotes.. But when the file has a space (like 'sachin knock.flv') or files which have quotes (like sachin's_double_cent.mp4) it doesn't work.. What can i do to get those files work accurately? One restriction is that i can't rename files as they are lump some.. My code is <?php error_reporting(E_ALL); extension_loaded('ffmpeg') or die('Error in loading ffmpeg'); $link = mysql_connect('localhost', 'root', ''); if (!$link) { die('Not connected : ' . mysql_error()); } $db_selected = mysql_select_db('db', $link); $max_width = 120; $max_height = 72; $path ="/home/rootuser/public_html/temp/"; $qry="select id, input_file, output_file from videos where thumbnail='' or thumbnail is null;"; $res=mysql_query($qry); while($row = mysql_fetch_array($res,MYSQL_ASSOC)) { $orig_str = array(" "); $rep_str = array("\ "); $outfile = $row[output_file]; // $infile = $row[input_file]; $infile1 = str_replace($orig_str, $rep_str, $outfile); $tmp = explode(".",$infile1); $tmp_name = $tmp[0]; $imgname = $tmp_name.".png"; $srcfile = "/home/rootuser/public_html/uploaded_vids/".$outfile; echo exec("ffmpeg -i ".$srcfile." -r 1 -ss 00:00:05 -f image2 -s 120x72 ".$path.$imgname); $nname = "./temp/".$imgname; $fileo = fopen($nname,"rb"); if($fileo) { $imgData = addslashes(file_get_contents($nname)); echo $imgdata; $qryy="update videos set thumbnail='{$imgData}' where input_file='$outfile'"; $ress=mysql_query($qryy); } else echo "Could not open<br><br>"; unlink('$nname'); } ?>

• Return only the new database items since last check in Rails

  - by Smith

  I'm fairly new to Ruby, and currently trying to implement an AJAX style commenting system. When the user views a topic, all the current comments on that topic will be displayed. The user can post a comment on the page of a topic and it should automatically display without having to refresh the page, along with any new comments that have been posted since the last comment currently displayed to the user. The comments should also automatically refresh at a specified frequency. I currently have the following code: views/idea/view.html.erb <%= periodically_call_remote(:update => "div_chat", :frequency => 1, :position => "top", :url => {:controller => "comment", :action => :test_view, :idea_id => @idea.id } ) %> <div id="div_chat"> </div> views/comment/test_view.html.erb <% @comments.each do |c| %><div id="comment"> <%= c.comment %> </div> <% end %> controllers/comment_controller.rb class CommentController < ApplicationController before_filter :start_defs def add_comment @comment = Comment.new params[:comment] if @comment.save flash[:notice] = "Successfully commented." else flash[:notice] = "UnSuccessfully commented." end end def test_render @comments = Comment.find_all_by_idea_id(params[:idea_id], :order => "created_at DESC", :conditions => ["created_at > ?", @latest_time] ) @latest = Comment.find(:first, :order => "created_at DESC") @latest_time = @latest.created_at end def start_defs @latest = Comment.find(:first, :order => "created_at ASC") @latest_time = @latest.created_at end end The problem is that every time periodically_call_remote makes a call, it returns the entire list of comments for that topic. From what I can tell, the @latest_time gets constantly reset to the earliest created_at, rather than staying updated to the latest created_at after the comments have been retrieved. I'm also not sure how I should directly refresh the comments when a comment is posted. Is it possible to force a call to periodically_call_remote on a successful save?

• Getting RGB values for each pixel from a 24bpp Bitmap in C

  - by seven

  Hello, i want to read the RGB values for each pixel from a .bmp file , so i can convert the bmp into a format suitable for gba . so i need to get just the RGB for each pixel and then write this information to a file. i am trying to use the windows.h structures : typedef struct { char signature[2]; unsigned int fileSize; unsigned int reserved; unsigned int offset; }BmpHeader; typedef struct { unsigned int headerSize; unsigned int width; unsigned int height; unsigned short planeCount; unsigned short bitDepth; unsigned int compression; unsigned int compressedImageSize; unsigned int horizontalResolution; unsigned int verticalResolution; unsigned int numColors; unsigned int importantColors; }BmpImageInfo; typedef struct { unsigned char blue; unsigned char green; unsigned char red; unsigned char reserved; }Rgb; typedef struct { BmpHeader header; BmpImageInfo info; Rgb colors[256]; unsigned short image[1]; }BmpFile; but i only need RGB struct. So lets say i read "in.bmp": FILE *inFile, *outFile; inFile = fopen("C://in.bmp", "rb"); Rgb Palette[256]; for(i=0;i<256;i++) { fread(&Palette[i],sizeof(Rgb),1,inFile); } fclose(inFile); is this correct ? how do i write only the RGB information to a file ? can anyone please give me some information please . Thank you.

• Thin & Sinatra not taking port

  - by NekoNova

  I'm having problems settig up my application using Thin and Sinatra. I have created a development-config.ru file that contains the following settings: # This is a rack configuration file to fire up the Sinatra application. # This allows better control and configuration as we are using the modular # approach here for controlling our application. # # Extend the Ruby load path with the root of the API and the lib folder # so that we can automatically include all our own custom classes. This makes # the requiring of files a bit cleaner and easier to maintain. # This is basically what rails does as well. # We also store the root of the API in the ENV settings to ensure we have # always access to the root of the API when building paths. ENV['API_ROOT'] = File.dirname(__FILE__) $:.unshift ENV['API_ROOT'] $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'lib')) $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'db')) # Now we can require all the gems used for the entire API by simpling requiring # them here. We can also include the classes that we have defined inside the lib # folder. require 'rubygems' require 'bundler' # Run Bundler to setup our gems properly. This will install all the missing gems on # the system and ensure that the deployment environment is ready to run. Bundler.require # To make the loading easier for the application, we will now automatically load all # models that have been defined inside the lib folder. This ensures that we do not need # to load them anymore anywhere else in our application, as the models will be known to # ruby everywhere. Dir.glob(File.join(ENV['API_ROOT'], 'lib', '**', '*.rb')).each{|file| require file} # Now we will configure the Sinatra application so that we can fire up the entire API. # This requires some detailed settings like whether logging is allowed, the port to be # used and some folder locations. require 'sinatra' require 'app' set :logging, true set :dump_errors, true set :port, 3001 set :views, "#{ENV['API_ROOT']}/views" set :public_folder, "#{ENV['API_ROOT']}/public" set :environment, :test # Start up the Sinatra application with all the settings that we have defined. run App.new This is based upon the information I found on the Sinatra website. However, the problem is that I cannot get the application running on port 3001. If I use thin start -R development-config.ru it runs on port 3000. If I use rackup config-development.ru it runs on port 9696. However I never see Sinatra kick in or run over port 3000. My application looks like this: # Author : Arne De Herdt # Email : # This is the actuall application that will be running under Sinatra # to serve the requests for the billing middleware API. # We use the modular approach here to allow control when deploying # the application using Capistrano. require 'sinatra/base' require 'logger' require 'savon' require 'billcrux' class App < Sinatra::Base # This action responds to POST requests on the URI '/billcrux/register' # and is responsible for handeling registration requests with the # BillCrux payment system. # The post "/billcrux/register" do # do stuff end end Can someone tell me what I am doing wrong?

• Rails Tutorial Chapter 4 2nd Ed. Title Helper not being called with out argument.

  - by SuddenlyAwakened

  I am running through the Rails Tutorial by Michael Hartl (Screen Cast). Ran into the and issue in chapter 4 on the title helper. I have been putting my own twist on the code as I go to make sure I understand it all. However on this one I it is very similar and I am not quite sure why it is acting the way it is. Here is the code: Application.html.erb <!DOCTYPE html> <html> <head> <%- Rails.logger.info("Testing: #{yield(:title)}") %> <title><%= full_title(yield(:title)) %></title> <%= stylesheet_link_tag "application", :media => "all" %> <%= javascript_include_tag "application" %> <%= csrf_meta_tags %> </head> <body> <%= yield %> </body> </html> Application_helper.rb module ApplicationHelper def full_title(page_title) full_title = "Ruby on Rails Tutorial App" full_title += " | #{page_title}" unless page_title.blank? end end Home.html.erb <h1><%= t(:sample_app) %></h1> <p> This is the home page for the <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a> sample application </p> about.html.erb <% provide(:title, t(:about_us)) %> <h1><%= t(:about_us) %></h1> <p> The <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a> is a project to make a book and screencast to teach web development with <a href="http://railstutorial.org/">Ruby on Rails</a>. This is the sample application for the tutorial. </p> What Happens: The code works fine when I set the provide method like on the about page. However when I do not it does not seem to even call the helper. I am assuming that because no title is passed back. Any ideas on what I am doing wrong? Thank you all for your help.

• devise register confirmation

  - by mattherick

  hello! i have a user and an admin role in my project. i created my authentification with devise, really nice and goot tool for handling the authentification. in my admin role i don´t have any confirmation or something like that. it is really simple and doesn´t make problems. but in my user model i have following things: model: devise :database_authenticatable, :confirmable, :recoverable, :rememberable, :trackable, :validatable, :timeoutable, :registerable # Setup accessible (or protected) attributes for your model attr_accessible :email, :username, :prename, :surname, :phone, :street, :number, :location, :password, :password_confirmation and few validations, but they aren´t relevant this time. my migration looks like following one: class DeviseCreateUsers < ActiveRecord::Migration def self.up create_table(:users) do |t| t.database_authenticatable :null = false t.confirmable t.recoverable t.rememberable t.trackable t.timeoutable t.validateable t.string :username t.string :prename t.string :surname t.string :phone t.string :street t.integer :number t.string :location t.timestamps end add_index :users, :email, :unique => true add_index :users, :confirmation_token, :unique => true add_index :users, :reset_password_token, :unique => true add_index :users, :username, :unique => true add_index :users, :prename, :unique => false add_index :users, :surname, :unique => false add_index :users, :phone, :unique => false add_index :users, :street, :unique => false add_index :users, :number, :unique => false add_index :users, :location, :unique => false end def self.down drop_table :users end end into my route.rb I added following statements: map.devise_for :admins map.devise_for :users, :path_names = { :sign_up = "register", :sign_in = "login" } map.root :controller = "main" and now my problem.. if I register a new user, I fill in all my data in the register form and submit it. After that I get redirected to the controller main with the flash-notice "You have signed up successfully." And I am logged in. But I don´t want to be logged in, because I don´t have confirmed my new user account yet. If I open the console I see the last things in the logs and there I see the confirmation-mail and the text and all stuff, but I am already logged in... I can´t explain why, ... does somebody of you have an idea? If I copy out the confirmation-token from the logs and confirm my account, I can log in, but if I don´t confirm, I also can log in..

• Downloading large file with php

  - by Alessandro

  Hi, I have to write a php script to download potentially large files. The file I'm reporting here works fine most of the times. However, if the client's connection is slow the request ends (with status code 200) in the middle of the downloading, but not always at the very same point, and not at the very same time. I tried to overwrite some php.ini variables (see the first statements) but the problem remains. I don't know if it's relevant but my hosting server is SiteGround, and for simple static file requests, the download works fine also with slow connections. I've found Forced downloading large file with php but I didn't understand mario's answer. I'm new to web programming. So here's my code. <?php ini_set('memory_limit','16M'); ini_set('post_max_size', '30M'); set_time_limit(0); include ('../private/database_connection.php'); $downloadFolder = '../download/'; $fileName = $_POST['file']; $filePath = $downloadFolder . $fileName; if($fileName == NULL) { exit; } ob_start(); session_start(); if(!isset($_SESSION['Username'])) { // or redirect to login (remembering this download request) $_SESSION['previousPage'] = 'download.php?file=' . $fileName; header("Location: login.php"); exit; } if (file_exists($filePath)) { header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); //header('Content-Disposition: attachment; filename='.$fileName); header("Content-Disposition: attachment; filename=\"$fileName\""); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); //header('Pragma: public'); header('Content-Length: ' . filesize($filePath)); ob_clean(); flush(); // download // 1 // readfile($filePath); // 2 $file = @fopen($filePath,"rb"); if ($file) { while(!feof($file)) { print(fread($file, 1024*8)); flush(); if (connection_status()!=0) { @fclose($file); die(); } } @fclose($file); } exit; } else { header('HTTP/1.1 404 File not found'); exit; } ?>

• Multiple layouts in rails [Newbie Q]

  - by BriteLite

  Hi. As a newb, I decided to build a "home inventory" application. I am now stuck on how to programmatically select a layout based on what type of item it is when viewing it in a browser. According to my planning, so far I should have created a few models to represent types of items I can find in my home: Furniture, Electronics and Books. class Book < ActiveRecord::Base end class Furniture < ActiveRecord::Base end class Electronic < ActiveRecord::Base end Now the Books model has things like isbn, pages, address, and category. Furniture model has things like color, price, address, and category. Electronics has things like name, voltage, address, and category. Here is where I got confused. I know the property address is going to be the same for all of them. I also know that, I will need to create multiple "layouts" for 3 different types of items to show the different properties of said items with appropriate graphics and stylesheets. But how will I go about deciding which category the item is so I can determine which layout to render. According to me, this is how I will do it: class DisplayController < ApplicationController def display @item = Params[:item] if @item.category = "electronics" render :layout => 'electronics' end end In my routes.rb map.display ':item', :controller => 'display', :action => 'display' I only seem to have one concern with this, I probably will add a lot of categories later on and think there should be a more DRY-esque way of dealing, rather than hardcoding them. I understand that I need to add into my layout html tags to display relevant information for that particular category. ----Questions---- Is this the right way to approach this type of problem. Will this approach be compatible when I decide to add a gem like *thinking_sphinx* to run search. What issues do you see with my approach and how can I make it better. I was reading something about "Polymorphic Assoc", does that apply in this case, since category exist for all items? Also, I was trying to get a routes to render a URL like "http://localhost/living-room-tv"

• B-trees, databases, sequential inputs, and speed.

  - by IanC

  I know from experience that b-trees have awful performance when data is added to them sequentially (regardless of the direction). However, when data is added randomly, best performance is obtained. This is easy to demonstrate with the likes of an RB-Tree. Sequential writes cause a maximum number of tree balances to be performed. I know very few databases use binary trees, but rather used n-order balanced trees. I logically assume they suffer a similar fate to binary trees when it comes to sequential inputs. This sparked my curiosity. If this is so, then one could deduce that writing sequential IDs (such as in IDENTITY(1,1)) would cause multiple re-balances of the tree to occur. I have seen many posts argue against GUIDs as "these will cause random writes". I never use GUIDs, but it struck me that this "bad" point was in fact a good point. So I decided to test it. Here is my code: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[T1]( [ID] [int] NOT NULL CONSTRAINT [T1_1] PRIMARY KEY CLUSTERED ([ID] ASC) ) GO CREATE TABLE [dbo].[T2]( [ID] [uniqueidentifier] NOT NULL CONSTRAINT [T2_1] PRIMARY KEY CLUSTERED ([ID] ASC) ) GO declare @i int, @t1 datetime, @t2 datetime, @t3 datetime, @c char(300) set @t1 = GETDATE() set @i = 1 while @i < 2000 begin insert into T2 values (NEWID(), @c) set @i = @i + 1 end set @t2 = GETDATE() WAITFOR delay '0:0:10' set @t3 = GETDATE() set @i = 1 while @i < 2000 begin insert into T1 values (@i, @c) set @i = @i + 1 end select DATEDIFF(ms, @t1, @t2) AS [Int], DATEDIFF(ms, @t3, getdate()) AS [GUID] drop table T1 drop table T2 Note that I am not subtracting any time for the creation of the GUID nor for the considerably extra size of the row. The results on my machine were as follows: Int: 17,340 ms GUID: 6,746 ms This means that in this test, random inserts of 16 bytes was almost 3 times faster than sequential inserts of 4 bytes. Would anyone like to comment on this? Ps. I get that this isn't a question. It's an invite to discussion, and that is relevant to learning optimum programming.

I know the correct number of bytes are being sent as I print them out when received. Im sending the image file from python like so #open the image file and read it into an object imgfile = open (marked_image, 'rb') obj = imgfile.read() #get the no of bytes in the image and convert it to a string bytes = str(len(obj)) #send the number of bytes self.conn.send( bytes + '\n') if self.conn.sendall(obj) == None: imgfile.flush() imgfile.close() print 'Image Sent' else: print 'Error' Here is the android part , this is where I'm having the problem. Any suggestions on the best way to go about receiving the image and writing it to a file ? //read the number of bytes in the image String noOfBytes = in.readLine(); Toast.makeText(this, noOfBytes, 5).show(); byte bytes [] = new byte [Integer.parseInt(noOfBytes)]; //create a file to store the retrieved image File photo = new File(Environment.getExternalStorageDirectory(), "PostKey.jpg"); DataInputStream dis = new DataInputStream(link.getInputStream()); try{ os =new FileOutputStream(photo); byte buf[]=new byte[1024]; int len; while((len=dis.read(buf))>0) os.write(buf,0,len); Toast.makeText(this, "File recieved", 5).show(); os.close(); dis.close(); }catch(IOException e){ Toast.makeText(this, "An IO Error Occured", 5).show(); } EDIT: I still cant seem to get it working. I have been at it since and the result of all my efforts have either resulted in a file that is not the full size or else the app crashing. I know the file is not corrupt before sending server side. As far as I can tell its definitely sending too as the send all method in python sends all or throws an exception in the event of an error and so far it has never thrown an exception. So the client side is messed up . I have to send the file from the server so I cant use the suggestion suggested by Brian .

• Passing custom info to mongrel_rails start

  - by whaka

  One thing I really don't understand is how I can pass custom start-up options to a mongrel instance. I see that a common approach is the use environment variables, but in my environment this is not going to work because my rails application serves many different clients. Much code is shared between clients, but there are also many differences which I implement by subclassing controllers and views to overload or extend existing features or introduce new ones. To make this all work, I simply add the paths to client specific modules the module load path ($:). In order to start the application for a particular client, I could now use an environment variable like say, TARGET=AMAZONE. Unfortunately, on some systems I'm running multiple mongrel clusters, each cluster serving a different client. Some of these systems run under Windows and to start mongrel I installed mongrel_services. Clearly, this makes my environment variable unsuitable. Passing this extra bit of data to the application is proving to be a real challenge. For a start, mongrel_rails service_install will reject any [custom] command line parameters that aren't documented. I'm not too concerned as installing the services using the install program is trivial. However, even if I manage to install mongrel_services such that when run it passes the custom command line option --target to mongrel_rails start, I get an error because mongrel_rails doesn't recognize the switch. So here were the things I looked at: Pass an extra parameter: mongrel_rails start --target XYZ ... use a config file and add target:XYZ, then do: mongrel_rails start -C x:\myapp\myconfig.yml modify the file: Ruby\lib\ruby\gems\1.8\gems\mongrel-1.1.5-x86-mswin32-60\lib\mongrel\command.rb Perhaps I can use the --script option, but all docs that I found on it were for Unix 1 and 2 simply don't work. I played with 4 but never managed it to do anything. So I had no choice but to go with 3. While it is relatively simple, I hate changing ruby library code. Particularly disappointing is that 2 doesn't work. I mean what is so unreasonable about adding other [custom] options in the config file? Actually I think this is a fundamental piece that is missing in rails. Somehow, the application should be able to register and access command line arguments it expects. If anybody has a good idea how to do this more elegantly using the current infrastructure, I have a chocolate fish to give away!!!

• Attach file to mail using php

  - by ktsixit

  Hi all, I've created a form which contains an upload field file and some other text fields. I'm using php to send the form's data via email and attach the file. This is the code I'm using but it's not working properly. The file is normally attached to the message but the rest of the data is not sent. $body="bla bla bla"; $attachment = $_FILES['cv']['tmp_name']; $attachment_name = $_FILES['cv']['name']; if (is_uploaded_file($attachment)) { $fp = fopen($attachment, "rb"); $data = fread($fp, filesize($attachment)); $data = chunk_split(base64_encode($data)); fclose($fp); } $headers = "From: $email<$email>\n"; $headers .= "Reply-To: <$email>\n"; $headers .= "MIME-Version: 1.0\n"; $headers .= "Content-Type: multipart/related; type=\"multipart/alternative\"; boundary=\"----=MIME_BOUNDRY_main_message\"\n"; $headers .= "X-Sender: $first_name $family_name<$email>\n"; $headers .= "X-Mailer: PHP4\n"; $headers .= "X-Priority: 3\n"; $headers .= "Return-Path: <$email>\n"; $headers .= "This is a multi-part message in MIME format.\n"; $headers .= "------=MIME_BOUNDRY_main_message \n"; $headers .= "Content-Type: multipart/alternative; boundary=\"----=MIME_BOUNDRY_message_parts\"\n"; $message = "------=MIME_BOUNDRY_message_parts\n"; $message .= "Content-Type: text/html; charset=\"utf-8\"\n"; $message .= "Content-Transfer-Encoding: quoted-printable\n"; $message .= "\n"; $message .= "$body\n"; $message .= "\n"; $message .= "------=MIME_BOUNDRY_message_parts--\n"; $message .= "\n"; $message .= "------=MIME_BOUNDRY_main_message\n"; $message .= "Content-Type: application/octet-stream;\n\tname=\"" . $attachment_name .

Can you help me fix it?

• RoR custom routing/Method/View problem all methods come back as undefined

  - by Jeff

  I am playing with custom view and routes. I think that I have everything right but obviously not. Essentially I tried to copy the show method and show.html.erb but for some reason it will not work. My controller class fatherController < ApplicationController def show @father = Father.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @father } end end def ofmine @father = Father.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @father } end end end My routes.rb Parent::Application.routes.draw do resources :fathers do resources :kids end match 'hospitals/:id/ofmine' => 'father#show2' end when I go to 127.0.0.1:/father/1 it works fine but when I try to go to 127.0.0.1:/father/1/ofmine it gives the following error. It doesn't matter what the variable/method that is called; it occurs at the first one to be displayed. Both show.html.erb and show2.html.erb are the exact same files My Error from webserver commandline > Processing by fathersController#show2 > as HTML Parameters: {"id"=>"1"} > Rendered fathers/show2.html.erb within > layouts/application (31.6ms) Completed > in 37ms > > ActionView::Template::Error (undefined > method `name' for nil:NilClass): > 4: <td>Name</td><td></td> > 5: </tr> > 6: <tr> > 7: <td><%= @father.name %></td><td></td> > 8: </tr> > 9: <tr> > 10: <td>City</td><td>State</td> app/views/fathers/show2.html.erb:7:in > `_app_views_fatherss_show__html_erb___709193087__616989688_0' Error as displayed on actual page NoMethodError in Fathers#show2 Showing /var/ruby/chs/app/views/fathers/show2.html.erb where line #7 raised: undefined method `name' for nil:NilClass Extracted source (around line #7): 4: Name 5: 6: 7: <%= @father.name % 8: 9: 10: CityState If anyone could tell me what in the world I am doing wrong I would appreciate it greatly.

• Rails controller not rendering correct view when form is force-submitted by Javascript

  - by whazzmaster

  I'm using Rails with jQuery, and I'm working on a page for a simple site that prints each record to a table. The only editable field for each record is a checkbox. My goal is that every time a checkbox is changed, an ajax request updates that boolean attribute for the record (i.e., no submit button). My view code: <td> <% form_remote_tag :url => admin_update_path, :html => { :id => "form#{lead.id}" } do %> <%= hidden_field :lead, :id, :value => lead.id %> <%= check_box :lead, :contacted, :id => "checkbox"+lead.id.to_s, :checked => lead.contacted, :onchange => "$('#form#{lead.id}').submit();" %> <% end %> </td> In my routes.rb, admin_update_path is defined by map.admin_update 'update', :controller => "admin", :action => "update", :method => :post I also have an RJS template to render back an update. The contents of this file is currently just for testing (I just wanted to see if it worked, this will not be the ultimate functionality on a successful save)... page << "$('#checkbox#{@lead.id}').hide();" When clicked, the ajax request is successfully sent, with the correct params, and the action on the controller can retrieve the record and update it just fine. The problem is that it doesn't send back the JS; it changes the page in the browser and renders the generated Javascript as plain text rather than executing it in-place. Rails does some behind-the-scenes stuff to figure out if the incoming request is an ajax call, and I can't figure out why it's interpreting the incoming request as a regular web request as opposed to an ajax request. I may be missing something extremely simple here, but I've kind-of burned myself out looking so I thought I'd ask for another pair of eyes. Thanks in advance for any info!

• How to use jQuery to generate 2 new associated objects in a nested form?

  - by mind.blank

  I have a model called Pair, which has_many :questions, and each Question has_one :answer. I've been following this railscast on creating nested forms, however I want to generate both a Question field and it's Answer field when clicking on an "Add Question" link. After following the railscast this is what I have: ..javascripts/common.js.coffee: window.remove_fields = (link)-> $(link).closest(".question_remove").remove() window.add_fields = (link, association, content)-> new_id = new Date().getTime() regexp = new RegExp("new_" + association, "g") $(link).before(content.replace(regexp, new_id)) application_helper.rb: def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.simple_fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, "window.add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")", class: "btn btn-inverse") end views/pairs/_form.html.erb: <%= simple_form_for(@pair) do |f| %> <div class="row"> <div class="well span4"> <%= f.input :sys_heading, label: "System Heading", placeholder: "required", input_html: { class: "span4" } %> <%= f.input :heading, label: "User Heading", input_html: { class: "span4" } %> <%= f.input :instructions, as: :text, input_html: { class: "span4 input_text" } %> </div> </div> <%= f.simple_fields_for :questions do |builder| %> <%= render 'question_fields', f: builder %> <% end %> <%= link_to_add_fields "<i class='icon-plus icon-white'></i> Add Another Question".html_safe, f, :questions %> <%= f.button :submit, "Save Pair", class: "btn btn-success" %> <% end %> _question_fields.html.erb partial: <div class="question_remove"> <div class="row"> <div class="well span4"> <%= f.input :text, label: "Question", input_html: { class: "span4" }, placeholder: "your question...?" %> <%= f.simple_fields_for :answer do |builder| %> <%= render 'answer_fields', f: builder %> <% end %> </div> </div> </div> _answer_fields.html.erb partial: <%= f.input :text, label: "Answer", input_html: { class: "span4" }, placeholder: "your answer" %> <%= link_to_function "remove", "remove_fields(this)", class: "float-right" %> I'm especially confused by the reflect_on_association part, for example how does calling .new there create an association? I usually need to use .build Also for a has_one I use .build_answer rather than answers.build - so what does this mean for the jQuery part?

• [C] Programming problem: Storing values of an array in one variable

  - by OldMacDonald

  Hello, I am trying to use md5 code to calculate checksums of file. Now the given function prints out the (previously calculated) checksum on screen, but I want to store it in a variable, to be able to compare it later on. I guess the main problem is that I want to store the content of an array in one variable. How can I manage that? Probably this is a very stupid question, but maybe somone can help. Below is the function to print out the value. I want to modify it to store the result in one variable. static void MDPrint (mdContext) MD5_CTX *mdContext; { int i; for (i = 0; i < 16; i++) { printf ("%02x", mdContext->digest[i]); } // end of for } // end of function For reasons of completeness the used struct: /* typedef a 32 bit type */ typedef unsigned long int UINT4; /* Data structure for MD5 (Message Digest) computation */ typedef struct { UINT4 i[2]; /* number of _bits_ handled mod 2^64 */ UINT4 buf[4]; /* scratch buffer */ unsigned char in[64]; /* input buffer */ unsigned char digest[16]; /* actual digest after MD5Final call */ } MD5_CTX; and the used function to calculate the checksum: static int MDFile (filename) char *filename; { FILE *inFile = fopen (filename, "rb"); MD5_CTX mdContext; int bytes; unsigned char data[1024]; if (inFile == NULL) { printf ("%s can't be opened.\n", filename); return -1; } // end of if MD5Init (&mdContext); while ((bytes = fread (data, 1, 1024, inFile)) != 0) MD5Update (&mdContext, data, bytes); MD5Final (&mdContext); MDPrint (&mdContext); printf (" %s\n", filename); fclose (inFile); return 0; }

• Rails program is not being run on apache + passenger - only directory listing

  - by user909943

  I have successfully installed Phusion passenger + Apache 2 + Rails 3.1 program + git on a linux Debian 6. I ran passenger-install-apache2-module and followed the configuration instructions. I followed also the setup instructions at https://help.ubuntu.com/community/RubyOnRails#Configure%20Apache My program is in /var/www/myrailsproject and runs fine on webrick on my mac. When going to myhomepage.com (example) I only see directory listing. By preventing directory listing and setting Options -Indexes in < Document tag in /etc/apache2/sites-available default or myhomepage.com I get an error on my website: Forbidden You don't have permission to access / on this server. Apache/2.2.19 (Debian) Server at myhomepage.com Port 80 In /etc/apache2/apache.conf I added: ServerName myhomepage.com LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.8/ext/apache2/mod_passenger.so PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.8 PassengerRuby /usr/bin/ruby1.8 In /etc/apache2/sites-available myhomepage.com: < VirtualHost *:80 ServerName myhomepage.com ServerAlias www.myhomepage.com DocumentRoot /var/www/myrailsproject/public ErrorLog /var/www/logs/error.log CustomLog /var/www/logs/access.log combined RailsEnv test RackEnv test RailsBaseURI /mayrailsproject < Directory /var/www/myrailsproject> Options -Indexes FollowSymLinks -MultiViews AllowOverride all Order allow,deny allow from all < /Directory> < Directory /var/www/myrailsproject/public> AllowOverride All Options -Indexes +FollowSymLinks MultiViews Order allow,deny Allow from all < /Directory> RailsSpawnMethod smart PassengerPoolIdleTime 1000 RailsAppSpawnerIdleTime 0 RailsFrameworkSpawnerIdleTime 0 PassengerMaxRequests 5000 PassengerStatThrottleRate 5 < /VirtualHost I think I have tried all possible combinations of values and variables in < Directory (and < Directory /, < Directory /var/www etc.) the dafault looks like: < VirtualHost *:80 ServerName myhomepage.com RailsBaseURI /myrailsproject DocumentRoot /var/www/myrailsproject/public RackEnv test RailsEnv test < Directory /var/www/myrailsproject> Options -Indexes FollowSymLinks -MultiViews AllowOverride None Order deny,allow Deny from all < /Directory> <Directory /root/public/myrailsproject/public> Options -Indexes FollowSymLinks -MultiViews AllowOverride All Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /doc/ "/usr/share/doc/" < Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 < /Directory> < /VirtualHost So I wonder why my rails project is not being run, only directory listing. I do not have any index file in my project, routes.rb routes to root :to = 'static_pages#home' I think all permissions are as they should be. Thanks a lot in advance Regards Íris
