  • Is Ruby on Rails' Active Record an example of Aspect-Oriented Programming?

    - by B Seven
    From Clean Code, about Cross-Cutting Concerns: Note that concerns like persistence tend to cut across the natural object boundaries of a domain. You want to persist all your objects using generally the same strategy, for example, using a particular DBMS... Is Active Record an example of aspect-oriented programming? In AOP, modular constructs called aspects specify which points in the system should have their behavior modified in some consistent way to support a particular concern. This specification is done using a succinct declarative or programmatic mechanism. If Active Record is an example of AOP, what is the "aspect"? Is it the class declaration that inherits from Active Record? class Foo < ActiveRecord::Base

  • best/simplest way to inform search engine of sitemap location

    - by Don
    AFAIK, there are 2 ways to make search engines aware of a sitemap's location: Include an absolute link to it in robots.txt Submit it to them directly. The relevant URLs are: http://www.google.com/webmasters/tools/ping?sitemap=SITEMAP_URL http://www.bing.com/webmaster/ping.aspx?sitemap=SITEMAP_URL Where SITEMAP_URL is the absolute URL of the sitemap. Currently, I do both. Regarding (2), I have a job that runs automatically every day which submits the sitemap to Bing and Google. I don't think there's any reason to do (1) and (2), but I'm paranoid, so I do. I imagine you can avoid both (1) and (2) if you just make your sitemap accessible at a conventional URL (like robots.txt). What's the simplest and most reliable way to ensure that search engines can find your sitemap?

  • Content Optimization only?

    - by danie7L T
    There are tons of discussions around tips&tricks to improve Search Engines "ranking" and SEOs. What if the focus of the webmaster/client is 100% set on the quality of the content with precise keywords in meta tags, clean design, regular articles updates, clean URLs and highly filtered external links leading to pages on websites dealing on the same,or related subjects; isn't it the job of a good search engine like Google to catch this website and show it in its front-page ? Or does Search Engines count on us to help them find us, and webmasters will always have to be up-to-date regarding SEO tools and rules updates on top of websites' design, browsers customization, progressive enhancement etc ?

  • Ruby on rails not popular in big international IT companies?

    - by maro
    I would like to ask you for advice more experienced ROR developers. I am new in programming and like to idea of ROR and I am before the decision on which programing language to specialize Java vs ROR. In the future I wish to learn for bigger international IT companies (IBM, Accenture etc.) but as I am reading their job openings, most of them are hiring Java, C++, .NET... Is the ROR used only in startups or also in bigger companies as well? What should be the reasons of their preference of Java over ROR?

  • When working with gems in Rails, what does 'cannot remove Object::ClassMethods' stem from?

Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling. I'm running bundle install and this is in my Gemfile: gem 'mysql2', '~> 0.3.11' I've currently got MySQL running through MAMP. I'm not sure if this is a bad idea and I should run a vanilla MySQl but it seems my current problem is just getting the gem installed. I've seen quite a few of these problems here on stackoverflow but all seem a bit different or have really complicated solutions. Is there something I'm missing? Something simple? Something stupid? I can provide additional info from the out file if necessary. I've read that some people use SQLite for dev and test then MySQL in prod but that sounds like a pretty horrible idea.

  • Rails destroy confirm with Jquery AJAX

    - by Mike
    I have got this working for the most part. My rails link is: <%= link_to(image_tag('/images/bin.png', :alt => 'Remove'), @business, :class => 'delete', :confirm => 'Are you sure?', :id => 'trash') %> :class = "delete" is calling an ajax function so that it is deleted and the page isn't refreshed that works great. But because the page doesn't refresh, it is still there. So my id trash is calling this jquery function: $('[id^=trash]').click(function(){ var row = $(this).closest("tr").get(0); $(row).hide(); return false; }); Which is hiding the row of whatever trash icon i clicked on. This also works great. I thought I had it all worked out and then I hit this problem. When you click on my trash can I have this confirm box pop up to ask you if you are sure. Regardless of whether you choose cancel or accept, the jquery fires and it hides the row. It isn't deleted, only hidden till you refresh the page. I tried changing it so that the prompt is done through jquery, but then rails was deleteing the row regardless of what i choose in my prompt because the .destroy function was being called when the prompt was being called. My question really is how can i get the value to cancel or accept from the rails confirm pop up so that in my jquery I can have an if statement that hides if they click accept and does nothing if they click cancel. EDIT: Answering Question below. That did not work. I tried changing my link to: <%= link_to(image_tag('/images/bin.png', :alt => 'Remove'), @business, :class => "delete", :onclick => "trash") %> and putting this in my jquery function trash(){ if(confirm("Are you sure?")){ var row = $(this).closest("tr").get(0); $(row).hide(); return false; } else { //they clicked no. } } But the function was never called. It just deletes it with no prompt and doesn't hide it. But that gave me an idea. I took the delete function that ajax was calling $('a.delete').click (function(){ $.post(this.href, {_method:'delete'}, null, "script"); $(row).hide(); }); And modified it implementing your code: remove :confirm = 'Are you sure?' $('a.delete').click (function(){ if(confirm("Are you sure?")){ var row = $(this).closest("tr").get(0); $.post(this.href, {_method:'delete'}, null, "script"); $(row).hide(); return false; } else { //they clicked no. return false; } }); Which does the trick.

  • how to user ajax with json in ruby on rails

    - by fenec
    I am implemeting a facebook application in rails using facebooker plugin, therefore it is very important to use this architecture if i want to update multiple DOM in my page. if my code works in a regular rails application it would work in my facebook application. i am trying to use ajax to let the user know that the comment was sent, and update the comments bloc. migration: class CreateComments < ActiveRecord::Migration def self.up create_table :comments do |t| t.string :body t.timestamps end end def self.down drop_table :comments end end controller: class CommentsController < ApplicationController def index @comments=Comment.all end def create @comment=Comment.create(params[:comment]) if request.xhr? @comments=Comment.all render :json=>{:ids_to_update=>[:all_comments,:form_message], :all_comments=>render_to_string(:partial=>"comments" ), :form_message=>"Your comment has been added." } else redirect_to comments_url end end end view: <script> function update_count(str,message_id) { len=str.length; if (len < 200) { $(message_id).innerHTML="<span style='color: green'>"+ (200-len)+" remaining</span>"; } else { $(message_id).innerHTML="<span style='color: red'>"+ "Comment too long.

  • Ruby XMLRPC::CLIENT issue under Rails 2.3.5 with Ruby 1.8.6

    - by TallGreenTree
    I'm trying to implement a ping to an xmlrpc server written in PHP under CodeIgniter. The system currently works as expected when receiving pings from WordPress-based blogs, but I'm unable to generate a successful ping from Rails. The code I'm using to generate the ping is: server = XMLRPC::Client.new("digital466.local", "/schafercondoncarter/xmlrpc") result = server.call_async("ping", BLOG_CONFIG['title'], "http://digital466.local:3000") The code runs fine in Console, and retrieves a correctly formatted response from the server, but when I integrate the code into a rails observer or controller, I receive the following error message: Timeout::Error in PostsController#update execution expired RAILS_ROOT: /Users/digital466/Sites/sccblog Application Trace | Framework Trace | Full Trace /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/timeout.rb:60:in `rbuf_fill' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:132:in `rbuf_fill' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:116:in `readuntil' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:126:in `readline' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:2020:in `read_status_line' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:2009:in `read_new' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:1050:in `request' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:992:in `post2' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/xmlrpc/client.rb:529:in `do_rpc' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/http.rb:543:in `start' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/xmlrpc/client.rb:528:in `do_rpc' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/xmlrpc/client.rb:435:in `call2_async' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/xmlrpc/client.rb:425:in `call_async' /Users/digital466/Sites/sccblog/app/controllers/posts_controller.rb:89:in `update' Any assistance would be appreciated.

  • Rails: Single Table Inheritance and models subdirectories

    - by Chris
    I have a card-game application which makes use of Single Table Inheritance. I have a class Card, and a database table cards with column type, and a number of subclasses of Card (including class Foo < Card and class Bar < Card, for the sake of argument). As it happens, Foo is a card from the original printing of the game, which Bar is a card from an expansion. In an attempt to rationalise my models, I have created a directory structure like so: app/ + models/ + card.rb + base_game/ + foo.rb + expansion/ + bar.rb And modified environment.rb to contain: Rails::Initializer.run do |config| config.load_paths += Dir["#{RAILS_ROOT}/app/models/**"] end However, when my reads a card from the database, Rails throws the following exception: ActiveRecord::SubclassNotFound (The single-table inheritance mechanism failed to locate the subclass: 'Foo'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite Card.inheritance_column to use another column for that information.) Is it possible to make this work, or am I doomed to a flat directory structure?

  • Rails App hangs after few requests

    - by Paddy
    I have Bitnami Rails stack installed on my Mac. To better explain my problem i created a simple scaffold based rails app with mysql as the backend. I can get to perform simple POST and GET requests for a while and after a few requests the app just hangs indefinitely. No exception caught or anything worthwhile in the development log to report this strange behavior. This is the last bit from the development log before the app froze: Processing WritedatasController#index (for 127.0.0.1 at 2010-03-30 20:38:51) [GET] [4;36;1mWritedata Load (0.7ms) [0m [0;1mSELECT * FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/index [4;35;1mWritedata Columns (2.9ms) [0m [0mSHOW FIELDS FROM `writedatas` [0m Completed in 99ms (View: 88, DB: 4) | 200 OK [http://localhost/writedatas] [4;36;1mSQL (0.2ms) [0m [0;1mSET NAMES 'utf8' [0m [4;35;1mSQL (0.1ms) [0m [0mSET SQL_AUTO_IS_NULL=0 [0m Processing WritedatasController#new (for 127.0.0.1 at 2010-03-30 20:38:52) [GET] [4;36;1mWritedata Columns (2.0ms) [0m [0;1mSHOW FIELDS FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/new Rendered writedatas/_form (5.9ms) Completed in 34ms (View: 25, DB: 2) | 200 OK [http://localhost/writedatas/new] [4;36;1mSQL (0.4ms) [0m [0;1mSET NAMES 'utf8' [0m [4;35;1mSQL (0.1ms) [0m [0mSET SQL_AUTO_IS_NULL=0 [0m Processing WritedatasController#index (for 127.0.0.1 at 2010-03-30 20:39:17) [GET] [4;36;1mWritedata Load (0.7ms) [0m [0;1mSELECT * FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/index [4;35;1mWritedata Columns (2.6ms) [0m [0mSHOW FIELDS FROM `writedatas` [0m Completed in 101ms (View: 90, DB: 4) | 200 OK [http://localhost/writedatas] It just hung at this point.

  • open flash chart rails x-axis issue

    - by Jimmy
    Hey guys, I am using open flash chart 2 in my rails application. Everything is looking smooth except for the range on my x axis. I am creating a line to represent cell phone plan cost over a specific amount of usage and I'm generate 8 values, 1-5 are below the allowed usage while 6-8 are demonstrations of the cost for usage over the limit. The problem I'm encountering is how to set the range of the X axis in ruby on rails to something specific to the data. Right now the values being displayed are the indexes of the array that I'm giving. When I try to hand a hash to the values the chart doesn't even load at all. So basically I need help getting a way to set the data for my line properly so that it displays correctly, right now it is treating every value as if it represents the x value of the index of the array. Here is a screen shot which may be a better description than what I am saying: http://i163.photobucket.com/albums/t286/Xeno56/Screenshot.png Note that those values are correct just the range on the x-axis is incorrect, it should be something like 100, 200, 300, 400, 500, 600, 700 Code: y = YAxis.new y.set_range(0,100, 20) x_legend = XLegend.new("Usage") x_legend.set_style('{font-size: 20px; color: #778877}') y_legend = YLegend.new("Cost") y_legend.set_style('{font-size: 20px; color: #770077}') chart =OpenFlashChart.new chart.set_x_legend(x_legend) chart.set_y_legend(y_legend) chart.y_axis = y line = Line.new line.text = plan.name line.width = 2 line.color = '#006633' line.dot_size = 2 line.values = generate_data(plan) chart.add_element(line) def generate_data(plan) values = [] #generate below threshold numbers 5.times do |x| usage = plan.usage / 5 * x cost = plan.cost * 10 values << cost end #generate above threshold numbers 3.times do |x| usage = plan.usage + ((plan.usage / 5) * x) cost = plan.cost + (usage * plan.overage) values << cost end return values end

  • Rails PDF Generation with Prawn in IE7

    - by fluid_chelsea
    I'm using Prawn and Prawnto to generate a PDF in a Ruby on Rails app (Rails version 2.2.2) which works great and generates PDFs happily and sends them to the user to download in Firefox. The problem is in IE7. I have a route set up like so: map.invoice_pdf '/invoices.pdf', :controller => 'invoices', :action => 'index', :format => 'pdf' Which I then have a link like so to call: invoice_pdf_path(:year => params[:year], :month => params[:month], :unpaid_only => params[:unpaid_only]) And the following in my controller: def index params[:year] = default params[:year] params[:month] = default params[:month] params[:page] ||= 1 @invoices = Arobl.find_invoices_for_customer(current_customer.strCustomerID, params) respond_to do |format| format.html{ render :action => 'index' } format.pdf{ prawnto :inline => false, :filename => "#{current_customer.strCustomerID}_invoice.pdf" end In FF this works as expected, when the link is clicked the show action is invoked with a format of .pdf, and responds with the correctly named PDF. When it's hit with IE7 it says that the file or website could not be found, and references "invoices.pdf" instead of the expected customer_id_invoice.pdf filename. Any idea what could be causing this behaviour? Thanks!

  • Change find method in database search so that it isn't case sensitive in Rails app

    - by Ryan
    Hello, I am learning Rails and have created a work-in-progress app that does one-word searches on a database of shortcut keys for various programs (http://keyboardcuts.heroku.com/shortcuts/home). The search method in the Shortcut model is the following: def self.search(search) search_condition = "%" + search + "%" find(:all, :conditions => ['action LIKE ? OR application LIKE ?', search_condition, search_condition]) end ...where 'action' and 'application' are columns in a SQLite table. (source: https://we.riseup.net/rails/simple-search-tutorial) For some reason, the search seems to be case sensitive (you can see this by searching 'Paste' vs. 'paste'). Can anyone help me figure out why and what I can do to make it not case sensitive? If not, can you at least point me in the right direction? Database creation: I first copied shortcuts from various website into Excel and saved it as a CSV. Then I migrated the database and filled it with the data using db:seed and a small script I wrote (I viewed the database and it looked fine). To get the SQLite database to the server, I used Taps as outline by the Heroku website (http://blog.heroku.com/archives/2009/3/18/push_and_pull_databases_to_and_from_heroku/). I am using Ubuntu. Please let me know if you need more information. Thanks in advance for you help, very much appreciated! Ryan

  • RMagic Error in rails, with AM Charts

    - by Elliot
    Hi Everyone, I'm using AMCharts and rails. AMCharts uses the Image Magic lib to export an image of the chart. In rails this is done with the gem, RMagic. In a controller this is implemented with the following controller method: def export width = params[:width].to_i height = params[:height].to_i data = {} img = Magick::Image.new(width, height) height.times do |y| row = params["r#{y}"].split(',') row.size.times do |r| pixel = row[r].to_s.split(':') pixel[0] = pixel[0].to_s.rjust(6, '0') if pixel.size == 2 pixel[1].to_i.times do (data[y] ||= []) << pixel[0] end else (data[y] ||= []) << pixel[0] end end width.times do |x| img.pixel_color(x, y, "##{data[y][x]}") end end img.format = "PNG" send_data(img.to_blob , :disposition => 'inline', :type => 'image/png', :filename => "chart.png?#{rand(99999999).to_i}") end When the controller is accessed however, I receive this error in the page: The change you wanted was rejected.

  • Business Logic Layer Pattern on Rails? MVCL

    - by Fabiano PS
    That is a broad question, and I appreciate no short/dumb asnwers like: "Oh that is the model job, this quest is retarded (period)" PROBLEM Where I work at people created a system over 2 years for managing the manufacture process over demand in the most simplified still broad as possible, involving selling, buying, assemble, The system is coded over Ruby On Rails. The app has been changed lots of times and the result is a mess on callbacks (some are called several times), 200+ models, and fat controllers: Total bad. The QUESTION is, if there is a gem, or pattern designed to handle Rails large app logic? The logic whould be able to fully talk to models (whose only concern would be data format handling and validation) What I EXPECT is to reduce complexity from various controllers, and hard to track callbacks into files with the responsibility to handle a business operation logic. In some cases there is the need to wait for a response, in others, only validation of the input is enough and a bg process would take place. ie: -- Sell some products (need to wait the operation to finish) 1. Set a View able to get the products input 2. Controller gets the product list inputed by employee and call the logic Logic::ExecuteWithResponse('sell', 'products', :prods => @product_list_with_qtt, :when => @date, :employee => current_user() ) This Logic would handle buying order, assemble order, machine schedule, warehouse reservation, and others. Have in mind that a callback on SalesOrder is not enough, since it depends on where it is called (no field for that), depends on the class of the user, among other stuff not visible for the model, or in some cases it would take long for the model to process.

  • Rails apps blew up on mediatemple's (dv) server

    - by BandsOnABudget
    i managed to fix this issue but i wanted to document it here for any others whom might have similar problems. I'm running a mediatemple (dv) rage server. monit started sending me alerts that i was having resource limitations on the server. logged into plesk and the CPU was pinned at 99.9%. Rebooted the server, catastrophe avoided... Not quite - all my rails apps were not loading My Setup ruby 1.8.6 Rails 2.3.5 w/ passenger installed as an apache module. I noticed a defunct ruby process so i killed and rebooted the server but runby continued to come back as defunct. Started trolling thru the apache log and i saw errors irt updating rubygems. i updated to the latest but then continued to get gem errors. Basically, I had to go thru all my apps and update any gems manually, reboot apache, and all was restored. Not really sure the cause of the issue but wanted to note it for posterity. Anybody else in the community ever have similar issues???

  • User avatar cropping/resizing with paperclip and jquery in rails

    - by Micke
    Hello fellow stackoverflow users. I am building my first Ruby on Rails app which is going to be my own little community. I have made the User model with several fields and information. But now i am thinking of adding avatar support for the users. And i've been researching and found that my best option would be using Paperclip. But then i've encountered a little dilemma. I want my users to be able to resie/crop their avatar image after they have chosen a image. I have googled alot and since i am using jQuery i found that imgAreaSelect would be best in my opinion. And i think MiniMagick looks best. So to my question. How can i best intergrate Paperclip and imgAreaSelect? I am new to Ruby and Rails so i don't know how i can resize the image. Do you folks know how to intergrate the to or maybe some other options that fits my needs best? I also need to apologize for my bad/misspelled english since i am not english :) Thanking you in advance. Yours sincerely, Micke.

  • how to create wizard forms in ruby on rails

    - by Branden Silva
    I'm trying to understand the best options for pulling off a wizard form in ruby on rails. Ideally I'd like to have it so the application signup has a back and next button that allows the user to submit data in steps. So in step 1 they could fill out contact info. Once they are done they could click next and be on step 2 to fill out payment info, etc. If they make a mistake, they can click back and correct it. Some steps will be required, while others will not, but you do have to make it to the last step to submit the data to the database to sign up. They then need the ability to go back and fill out the past steps in the same fashion after completion. (example: perhaps if they clicked on a profile link they could recomplete the steps in the same fashion because they didn't want to complete all the steps right away. Maybe by being given a skip button before they completed the steps to sign up?). I also need validation to happen on what steps have been completed preventing them from moving onto the next step until corrected or completed. Option 1) I've noticed that ajax has been recommended as an option in other questions on stackoverflow. The only problem I have with it is that the user would not be able to sign up if javascript was disabled. Ideally I'd like to have it be native to ruby on rails but I'm willing to work with whatever is necessary to get it to work.

  • Problems with Runt overlap? but *only* within Rails

    - by trisignia
    Martin Fowler's Runt library is really handy for date/time comparisons, and this code works great in an irb console: require 'runt' include Runt r_start = PDate.month(2010,12) r_end = PDate.month(2011,12) range = DateRange.new(r_start,r_end) o_start = PDate.month(2010,11) o_end = PDate.month(2012,2) o_range = DateRange.new(o_start,o_end) range.overlap?(o_range) but if I add the Runt gem to my Rails 2.3.5 app and try to run the same commands in script/console, I get this error: NoMethodError: undefined method `to_datetime' for Mon, 01 Nov 2010 00:00:00 +0000..Wed, 01 Feb 2012 00:00:00 +0000:Runt::DateRange from /Users/jacob/work/matchbook/vendor/gems/runt-0.7.6/lib/runt/sugar.rb:130:in method_missing' from /Users/jacob/work/matchbook/vendor/rails/activesupport/lib/active_support/core_ext/date_time/calculations.rb:120:in <=' from /Users/jacob/work/matchbook/vendor/gems/runt-0.7.6/lib/runt/pdate.rb:91:in <=>' from /Users/jacob/work/matchbook/vendor/gems/runt-0.7.6/lib/runt/daterange.rb:34:in member?' from /Users/jacob/work/matchbook/vendor/gems/runt-0.7.6/lib/runt/daterange.rb:34:in `overlap?' from (irb):10 Has anyone encountered this error before, or does anyone know how to begin debugging this?

  • Business Layer Pattern on Rails? MVCL

    - by Fabiano PS
    That is a broad question, and I appreciate no short/dumb asnwers like: "Oh that is the model job, this quest is retarded (period)" PROBLEM Where I work at people created a system over 2 years for managing the manufacture process over demand in the most simplified still broad as possible, involving selling, buying, assemble, The system is coded over Ruby On Rails. The result has been changed lots of times and the result is a mess on callbacks (some are called several times), 200+ models, and fat controllers: Total bad. The QUESTION is, if there is a gem, or pattern designed to handle Rails large app logic? The logic whould be able to fully talk to models (whose only concern would be data format handling and validation) What I EXPECT is to reduce complexity from various controllers, and hard to track callbacks into files with the responsibility to handle a business operation logic. In some cases there is the need to wait for a response, in others, only validation of the input is enough and a bg process would take place. ie: -- Sell some products (need to wait the operation to finish) 1. Set a View able to get the products input 2. Controller gets the product list inputed by employee and call the logic Logic::ExecuteWithResponse('sell', 'products', :prods => @product_list_with_qtt, :when => @date, :employee => current_user() ) This Logic would handle buying order, assemble order, machine schedule, warehouse reservation, and others

  • rails, mysql charsets & encoding: binary

    - by Benjamin Vetter
    Hi, i've a rails app that runs using utf-8. It uses a mysql database, all tables with mysql's default charset and collation (i.e. latin1). Therefore the latin1 tables contain utf-8 data. Sure, that's not nice, but i'm not really interested in it. Everything works fine, because the connection encoding is latin1 as well and therefore mysql does not convert between charsets. Only one problem: i need a utf-8 fulltext index for one table: mysql> show create table autocompletephrases; ... AUTO_INCREMENT=310095 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci But: I don't want to convert between charsets in my rails app. Therefore I would like to know if i could just set config/database.yml production: adapter: mysql >>>> encoding: binary ... which just calls SET NAMES 'binary' when connecting to mySQL. It looks like it works for my case, because i guess it forces mysql to -not- convert between charsets (mySQL docs). Does anyone knows about problems about doing this? Any side-effects? Or do you have any other suggestions? But i'd like to avoid converting my whole database to utf-8. Many Thanks! Benjamin

  • WYSIHAT Photos upload not working - Paperclip - Ruby on Rails

    - by bgadoci
    I just successfully installed WysiHat in my rails blog. Seems that the 'add a picture' feature is not working. It successfully allows me to find and select a picture from my desktop but upon clicking save, it does nothing. I also have Paperclip successfully installed. I am wondering if this may have something to do with it. Perhaps Paperclip is getting in the way, or, perhaps I need to connect Paperclip and WysiHat somehow. Any ideas? (let me know if I need to post any code). Also, WysiHat-engine uses facebox, not sure if that is relevant. UPDATE: Added Server Log, looks like paperclip is saving it so not sure what else is going wrong.
