  • Is it possible to do have Capistrano do a checkout over a reverse SSH tunnel?

    - by James A. Rosen
    I am developing an application that resides on a public host but whose source I must keep in a Git repository behind a corporate firewall. I'm getting very tired of the slowness of deploying via scp (copying the whole repository and shipping it over SSH on each deploy) and would like to have the remote host simply do a git pull to update. The problem is that the firewall prohibits incoming SSH connections. Would it be possible for me to set up an SSH tunnel from my computer to the deployment computer and use my repository as the source for the git pull? After all, git is distributed, so my copy is just as valid a repository as the central one. If this is possible, what would the tunnel command and the Capistrano configuration be? I think the tunnel will look something like ssh -R something:deployserver.com:something [email protected]

  • Using JSON Data to Populate a Google Map with Database Objects

    - by MikeH
    I'm revising this question after reading the resources mentioned in the original answers and working through implementing it. I'm using the google maps api to integrate a map into my Rails site. I have a markets model with the following columns: ID, name, address, lat, lng. On my markets/index view, I want to populate a map with all the markets in my markets table. I'm trying to output @markets as json data, and that's where I'm running into problems. I have the basic map displaying, but right now it's just a blank map. I'm following the tutorials very closely, but I can't get the markers to generate dynamically from the json. Any help is much appreciated! Here's my setup: Markets Controller: def index @markets = Market.filter_city(params[:filter]) respond_to do |format| format.html # index.html.erb format.json { render :json => @market} format.xml { render :xml => @market } end end Markets/index view: <head> <script type="text/javascript" src="http://www.google.com/jsapi?key=GOOGLE KEY REDACTED, BUT IT'S THERE" > </script> <script type="text/javascript"> var markets = <%= @markets.to_json %>; </script> <script type="text/javascript" charset="utf-8"> google.load("maps", "2.x"); google.load("jquery", "1.3.2"); </script> </head> <body> <div id="map" style="width:400px; height:300px;"></div> </body> Public/javascripts/application.js: function initialize() { if (GBrowserIsCompatible() && typeof markets != 'undefined') { var map = new GMap2(document.getElementById("map")); map.setCenter(new GLatLng(40.7371, -73.9903), 13); map.addControl(new GLargeMapControl()); function createMarker(latlng, market) { var marker = new GMarker(latlng); var html="<strong>"+market.name+"</strong><br />"+market.address; GEvent.addListener(marker,"click", function() { map.openInfoWindowHtml(latlng, html); }); return marker; } var bounds = new GLatLngBounds; for (var i = 0; i < markets.length; i++) { var latlng=new GLatLng(markets[i].lat,markets[i].lng) bounds.extend(latlng); map.addOverlay(createMarker(latlng, markets[i])); } } } window.onload=initialize; window.onunload=GUnload;

  • Call a block method on an iterator: each.magic.collect { ... }

    - by blinry
    I have a class with a custom each-method: class CurseArray < Array def each_safe each.do |element| unless element =~ "fuck" yield element end end end end And want to call block methods on those "selected" elements. For example: curse_array.each_safe.magic.collect {|element| "#{element} is a nice sentence."} I know there is a way to do this, but I've forgotten. Please help! :-)

  • active record relations – who needs it?

    - by M2_
    Well, I`m confused about rails queries. For example: Affiche belongs_to :place Place has_many :affiches We can do this now: @affiches = Affiche.all( :joins => :place ) or @affiches = Affiche.all( :include => :place ) and we will get a lot of extra SELECTs, if there are many affiches: Place Load (0.2ms) SELECT "places".* FROM "places" WHERE "places"."id" = 3 LIMIT 1 Place Load (0.3ms) SELECT "places".* FROM "places" WHERE "places"."id" = 3 LIMIT 1 Place Load (0.8ms) SELECT "places".* FROM "places" WHERE "places"."id" = 444 LIMIT 1 Place Load (1.0ms) SELECT "places".* FROM "places" WHERE "places"."id" = 222 LIMIT 1 ...and so on... And (sic!) with :joins used every SELECT is doubled! Technically we cloud just write like this: @affiches = Affiche.all( ) and the result is totally the same! (Because we have relations declared). The wayout of keeping all data in one query is removing the relations and writing a big string with "LEFT OUTER JOIN", but still there is a problem of grouping data in multy-dimentional array and a problem of similar column names, such as id. What is done wrong? Or what am I doing wrong? UPDATE: Well, i have that string Place Load (2.5ms) SELECT "places".* FROM "places" WHERE ("places"."id" IN (3,444,222,57,663,32,154,20)) and a list of selects one by one id. Strange, but I get these separate selects when I`m doing this in each scope: <%= link_to a.place.name, **a.place**( :id => a.place.friendly_id ) %> the marked a.place is the spot, that produces these extra queries.

  • Getting the first of a GROUP BY clause in SQL

    - by Michael Bleigh
    I'm trying to implement single-column regionalization for a Rails application and I'm running into some major headaches with a complex SQL need. For this system, a region can be represented by a country code (e.g. us) a continent code that is uppercase (e.g. NA) or it can be NULL indicating the "default" information. I need to group these items by some relevant information such as a foreign key (we'll call it external_id). Given a country and its continent, I need to be able to select only the most specific region available. So if records exist with the country code, I select them. If, not I want a records with the continent code. If not that, I want records with a NULL code so I can receive the default values. So far I've figured that I may be able to use a generated CASE statement to get an arbitrary sort order. Something like this: SELECT *, CASE region WHEN 'us' THEN 1 WHEN 'NA' THEN 2 ELSE 3 END AS region_sort FROM my_table WHERE region IN ('us','NA') OR region IS NULL GROUP BY external_id ORDER BY region_sort The problem is that without an aggregate function the actual data returned by the GROUP BY for a given row seems to be untameable. How can I massage this query to make it return only the first record of the region_sort ordered groups?

  • Internet Explorer not loading stylesheet.

  • Counting distinct and duplicate attribute values in an array

    - by keruilin
    I have an array of users that's sorted in descending order based on total_points. I need to find the rank of each user in that array. The issue is that more than one user can have the same total points and, thus, the same rank. For example, three users could be in 3rd place with 200 Points. Here's my current code: class Leader < ActiveRecord::Base def self.points_leaders all_leaders = all_points_leaders # returns array of users sorted by total_points in desc order all_leaders_with_rank = [] all_leaders.each do |user| rank = all_leaders.index(user)+1 all_leaders_with_rank << Ldr.new(rank, user) # Ldr is a Struct end return all_leaders_with_rank end end How must I modify the code so that the correct rank is returned, and not just the value of the index position?

  • Rails: Multiple "types" of one model through related models?

    - by neezer
    I have a User model in my app, which I would like to store basic user information, such as email address, first and last name, phone number, etc. I also have many different types of users in my system, including sales agents, clients, guests, etc. I would like to be able to use the same User model as a base for all the others, so that I don't have to include all the fields for all the related roles in one model, and can delegate as necessary (cutting down on duplicate database fields as well as providing easy mobility from changing one user of one type to another). So, what I'd like is this: User -- first name -- last name -- email --> is a "client", so ---- client field 1 ---- client field 2 ---- client field 3 User -- first name -- last name -- email --> is a "sales agent", so ---- sales agent field 1 ---- sales agent field 2 ---- sales agent field 3 and so on... In addition, when a new user signs up, I want that new user to automatically be assigned the role of "client" (I'm talking about database fields here, not authorization, though I hope to eventually include this logic in my user authorization as well). I have a multi-step signup wizard I'm trying to build with wizardly. The first step is easy, since I'm simply calling the fields included in the base User model (such as first_name and email), but the second step is trickier since it should be calling in fields from the associated model (like--per my example above--the model client with fields client_field_1 or client_field_2, as if those fields were part of User). Does that make sense? Let me know if that wasn't clear at all, and I'll try to explain it in a different way. Can anyone help me with this? How would I do this?

  • How do I create multiple submit buttons for the same form in Rails?

    - by Angela
    I need to have multiple submit buttons. I have a form which creates an instance of Contact_Call. One button creates it as normal. The other button creates it but needs to have a different :attribute value from the default, and it also needs to set the attribute on a different, but related model used in the controller. How do I do that? I can't change the route, so is there a way to send a different variable that gets picked up by [:params]? And if I do then, what do I do in the controller, set up a case statement?

  • How do I find the .max of an attribute value among a group of different Models?

    - by Angela
    Hi, everyone: I am also open to just straight-up refactoring what I'm finding to be pretty repetitive, but to give a baseline of how it's working.... I have for every contact a Campaign, which has_many of three types of Models: Email, Call, and Letter. When an Email (Call or Letter) has been executed for a specific contact, I have a Contact_Email(_or_Call_or_Letter) which belongs to both the Contact and the Model (Email_or_Call_or_Letter). Each Contact_Email for example pairing has a :date_sent attribute. So does each Contact_Call and Contact_Letter. How do I find the latest of all of them? Here is the code I wrote that can find the latest Email and my finding retyping similar code for Call and Letter, but then stuck on how to do a .max on all of them: def last_email(contact) #get campaign the contact belongs to @campaign = Campaign.find_by_id(contact.campaign_id) @last_email = ContactEmail.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") @last_call = ContactCall.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") @last_letter = ContactLetter.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") # how do I get the latest of all of these to display? if @last_sent_email.nil? return "no email sent" else return @last_sent_email.date_sent end end Question 1: With what I have, how can I find effectively @last_event given I can find the last Email, last Call, and last Letter for every contact? Question 2: How can I remove the repetitive code that I have to write for each Model?

  • Nginx: check content-length before file upload takes place

    - by robw
    I'm trying to prevent users from uploading (accidentally or maliciously) very large files to my website. I have nginx max_client_body_size set to 4M, but if a file larger than this is uploaded, then it uploads the entire file before returning 413 (entity too large). I want to make nginx check the Content-Length header, so that it rejects the request before it's uploaded. Alternatively, a Rails solution would also be acceptable. Any help appreciated.

  • Get pixel color with Rails or anything else

    - by ulf
    I'd like to build a webapp in Rails in which I'd like to determine every pixel's color of a given image (JPEG). Is there any possibility to do that with Rails or JavaScript? The goal is to write an algorithm which determines the "middle color" of the image and uses it for background color of the site. Any suggestion would be appreciated.

  • Get string value from http response with Mechanize

    - by Gearóid
    Hi, I'm currently integrating facebook into my current app and I've succeeded in retrieving the access_token using the following code: url="#{url}?#{client_id}&#{client_secret}&#{code}&#{redirect_uri}&type=client_cred" agent = Mechanize.new page = agent.get(url) The page object above has a body which contains text something along the lines of access_token=XXXXX I just want to pull out the access_token value. I can get the entire string simply by writing: page.body But I was wondering is there a way to get the access_token value without resorting to regular expressions etc? Thanks.

  • Stubbing a before_filter with RSpec

    - by TheDelChop
    Guys, I'm having trouble understanding why I can't seem to stub this controller method :load_user, since all of my tests fail if I change the actual implementation of :load_user to not return and instance of @user. Can anybody see why my stub (controller.stub!(:load_user).and_return(@user)) seems to fail to actually get called when RSpec makes a request to the controller? require 'spec_helper' describe TasksController do before(:each) do @user = Factory(:user) sign_in @user @task = Factory(:task) User.stub_chain(:where, :first).and_return(@user) controller.stub!(:load_user).and_return(@user) end #GET Index describe "GET Index" do before(:each) do @tasks = 7.times{Factory(:task, :user = @user)} @user.stub!(:tasks).and_return(@tasks) end it "should should find all of the tasks owned by a user" do @user.should_receive(:tasks).and_return(@tasks) get :index, :user_id = @user.id end it "should assign all of the user's tasks to the view" do get :index, :user_id = @user.id assigns[:tasks].should be(@tasks) end end #GET New describe "GET New" do before(:each) do @user.stub_chain(:tasks, :new).and_return(@task) end it "should return a new Task" do @user.tasks.should_receive(:new).and_return(@task) get :new, :user_id = @user.id end end #POST Create describe "POST Create" do before(:each) do @user.stub_chain(:tasks, :new).and_return(@task) end it "should create a new task" do @user.tasks.should_receive(:new).and_return(@task) post :create, :user_id = @user.id, :task = @task.to_s end it "saves the task" do @task.should_receive(:save) post :create, :user_id = @user.id, :task = @task end context "when the task is saved successfully" do before(:each) do @task.stub!(:save).and_return(true) end it "should set the flash[:notice] message to 'Task Added Successfully'"do post :create, :user_id = @user.id, :task = @task flash[:notice].should == "Task Added Successfully!" end it "should redirect to the user's task page" do post :create, :user_id = @user.id, :task = @task response.should redirect_to(user_tasks_path(@user.id)) end end context "when the task isn't saved successfully" do before(:each) do @task.stub(:save).and_return(false) end it "should return to the 'Create New Task' page do" do post :create, :user_id = @user.id, :task = @task response.should render_template('new') end end end it "should attempt to authenticate and load the user who owns the tasks" do context "when the tasks belong to the currently logged in user" do it "should set the user instance variable to the currently logged in user" do pending end end context "when the tasks belong to another user" do it "should set the flash[:notice] to 'Sorry but you can't view other people's tasks.'" do pending end it "should redirect to the home page" do pending end end end end class TasksController < ApplicationController before_filter :load_user def index @tasks = @user.tasks end def new @task = @user.tasks.new end def create @task = @user.tasks.new if @task.save flash[:notice] = "Task Added Successfully!" redirect_to user_tasks_path(@user.id) else render :action => 'new' end end private def load_user if current_user.id == params[:user_id].to_i @user = User.where(:id => params[:user_id]).first else flash[:notice] = "Sorry but you can't view other people's tasks." redirect_to root_path end end end Can anybody see why my stub doesnt' work? Like I said, my tests only pass if I make sure that load_user works, if not, all my tests fail which makes my think that RSpec isn't using the stub I created. Thanks, Joe

  • Multiple children in single form in rails

    - by CaptnCraig
    I have a model that has an arbitrary number of children entities. For simplicity lets call the entities Orders and Items. I would like to have a create Orders form where I input the order information, as well as add as many items as I want. If I click the "Add another item" button, a new set of form elements will be added to input the new data, amounts, etc.. I could hack this out in pure javascript, but I'm pretty sure there has to be a more magical, railsish way to do it, maybe with a partial view or something. I'm just a little too new to rails to know what it is. What is the best way to dynamically add the new form elements, and then to access them in the create controller?

  • Hashes or tokens for "remember me" cookies?

    - by Emanuil Rusev
    When it comes to remember me cookies, there are 2 distinct approaches: Hashes The remember me cookie stores a string that can identify the user (i.e. user ID) and a string that can prove that the identified user is the one it pretends to be - usually a hash based on the user password. Tokens The remember me cookie stores a random (meaningless), yet unique string that corresponds with with a record in a tokens table, that stores a user ID. Which approach is more secure and what are its disadvantages?

  • rails 3 cookies

    - by ralph
    I have a simple app where users type in stuff in a text filed to get various results. I would like a feature where if a user enters something and then closes the browser tab, the next time they come, I can show them their previous/recent searches. This will persist even if they close the whole browser and open it again. I believe this can be done by help of cookies. Are there some good rails3 gems for using cookies or any simple tutorial that could guide me in a direction?
