  • rails code within javascript

    - by Jesse
    I am trying to use some rails code withing a javascript and need to have that rails code be dynamically changed. Here's the line of code: $(this).replaceWith("<%= escape_javascript(render(:partial => 'shared/products')) %>"); The 'shared/products' is the part I want to change based off information passed earlier in the javascript. How do I insert a value from javascript so that instead of 'shared/products' the products portion can be a variable? Hope this makes sense. I'm not the most experienced jQuery/javascript programmer, so any help is very much appreciated. Thanks in advance!

  • Rubygame on OS X shebang problem

    - by Mk12
    I'm playing around with Rubygame. I installed it with the Mac Pack, and now I have the rsdl executable. rsdl game.rb works fine, but when I chmod +x the rb file, add the shebang to rsdl (tried direct path and /usr/bin/env rsdl) and try to execute it (./game.rb), it starts to flicker between the Terminal and rsdl which is trying to open, and eventually gives up and gives a bus error. Anyone know what's causing that? I'm on Snow Leopard (10.6.2) if it makes a difference. Thanks.

  • How can I override the attribute assignment in an active record object?

    - by ryeguy
    I know you can do this with virtual attributes, but what if the column actually exists? For example, my model has a raw_topic column. When raw_topic is set, I want artist and song_title to be set based off of raw_topic's contents. Ideally, I'd like to override the raw_topic= method, but rails doesn't seem to like that. What's the proper way of doing this? Is a callback the only way?

  • Rails has_and_belongs_to_many join across 3 tables

    - by Birdman
    I have a three models: listing, category, and site. There is a many to many relationship between listing and site and there is a many to many relationship between listing and category. A listing thus belongs to one or more sites and one or more categories (a listing can appear on multiple sites and multiple categories). Given a site id and a category id, I want a set of all the listings. I understand how to get the listings from a site id (listings = site.listings) and how to get the listings from a category id (listings = category.listings), but how do I get the triple join of the set of listings from both a site id and category id? The sql would look something like (sit_id and cat_id are input): select l.name from listings l, categories_listings cl, listings_sites, ls where cl.category_id = cat_id and ls.site_id = sit_id and cl.listing_id = l.id and ls.listing_id = l.id Thanks in advance

  • Is it possible to group validation?

    - by lambdabutz
    I am using a lot of my own validation methods to compare the data from one association to the other. I've noticed that I'm constantly checking that my associations aren't nil before trying to call anything on them, but I am also validating their presence, and so I feel that my nil checks are redundant. Here's an example: class House < ActiveRecord::Base has_one :enterance, :class => Door has_one :exit, :class => Door validates_presence_of :enterance, :exit validate :not_a_fire_hazard def not_a_fire_hazard if enterance && exit && enterance.location != exit.location errors.add_to_base('If there is a fire you will most likely die') return false end end end I feel like I am repeating myself by checking the existence of enterance and exit within my own validation. Is there a more "The Rails Way" to do this?

  • Running rspec against multiple targets

    - by kaerast
    I've written an rspec test using Watir against a web application and it's running fine. However, I now want to be able to run this test against the web application running on different domain names. My initial thought was that I'd be able to pass a value to spec at the command line to set a variable within my script, but I can't see any easy method of doing this. So my second thought was that I might need to add an array of domains into my script and have it test all of them - but I don't always want to test every domain, and the domains are constantly changing as we add and remove sites to be tested. What are my options for allowing the choice of targets I want?

  • What is the difference between a restful route method for getting an index vs. creating a new object

    - by Jason
    According to rake routes, there's the same path for getting an index of objects as there is for creating a new object: cars GET /cars(.:format) {:controller=>"plugs", :what=>"car", :action=>"index"} POST /cars(.:format) {:controller=>"plugs", :what=>"car", :action=>"create"} Obviously, the HTTP verb is what distinguishes between them. I want the "create" version of the cars_path method, not the "index" version. My question is what route method do you invoke to choose the one you want? I'm telling cucumber what path to generate with this: when /the car plug preview page for "(.+)"/ cars_path(:action => :create, :method => :post) ...but it always chooses the "index" action, not "create". I've tried lots of combinations for the hash argument following cars_path and nothing changes it from choosing "index" instead of "create". I'll get an error like this: cars_url failed to generate from {:controller=>"plugs", :method=>:post, :what=>"car", :action=>"create"}, expected: {:controller=>"plugs", :what=>"car", :action=>"index"}, diff: {:method=>:post, :action=>"index"} (ActionController::RoutingError) This seems like a very simple question but I've had no luck googling for it, so could use some advice. 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

  • Apache serving wrong Content-Type for Rails files

  • How do I let a user sign in from a different domain on Authlogic?

    - by Newy
    [This is slightly different than a previous question about having multiple domains share the same cookie. It seemed like there wasn't an easy way to do that.] I have a application at application.com. A customer has app.customer.com pointed at my site on Heroku, and I have everything set up so that it renders a specific version of app correctly. The issue is that I want a user at app.customer.com to be able to login. I believe authlogic is now setting the cookie on application.com, so while it verifies the credentials, no session on customer.com is ever created.

  • Saving an active record, in what order are the associated objects saved?

    - by Bryan
    In rails, when saving an active_record object, its associated objects will be saved as well. But has_one and has_many association have different order in saving objects. I have three simplified models: class Team < ActiveRecord::Base has_many :players has_one :coach end class Player < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end class Coach < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end I expected that when team.save is called, team should be saved before its associated coach and players. I use the following code to test these models: t = Team.new team.coach = Coach.new team.save! team.save! returns true. But in another test: t = Team.new team.players << Player.new team.save! team.save! gives the following error: > ActiveRecord::RecordInvalid: > Validation failed: Players is invalid I figured out that team.save! saves objects in the following order: 1) players, 2) team, and 3) coach. This is why I got the error: When a player is saved, team doesn't yet have a id, so validates_presence_of :team_id fails in player. Can someone explain to me why objects are saved in this order? This seems not logical to me.

  • Why use a Rails-like deployment mechanism over 'git pull' for releasing?

    - by Chad Johnson
    To release my centralized webapp, I COULD have a vhost pointed to some directory and then just do a 'git pull' when I want to release, updating the files. But Rails has a different deployment mechanism: it copies files to a subdirectory and then points a symlink ('current') to that new subdirectory. I understand that it probably more acceptable to do a Rails-like deployment because the release is built in some directory, and then the symlink is pointed to that directory, so this is much faster, and it's less likely that users would experience weird issues while a release is happening. Are there any other advantages to the Rails approach? Or, is a 'git pull' approach actually more widely accepted?

  • how do i set up a load balanced Rails web server using mongrel, lighttpd and iis on windows 2003

    - by user91519
    I understand that this is not the perfect environment for doing this but please stick with me and help if you can... The set up I want to achieve is to have my rails application running on a windows 2003 server, using a pack of mongrels with lighttpd acting as the load balancer and IIS in front of it all passing client requests to lighttpd. first of all i've followed these instructions: deploying to iis on windows And I've managed to get the application to run, BUT if the client clicks on a link button the app bombs out with a 500 server error. If I just run against one of the mongrel servers, the the app behaves ok, so I think its lightpd. Its almost as if the lighttpd gets confused with multiple GET requests (i.e. multiple clicks) and bombs out. Any help on why i'm getting 500 errors would be helpful, thanks.

  • getting numbers from lines of text

    - by Flethuseo
    Hi everyone, I want to parse a text file, where I get numbers that are between parenthesis like this: 1 2 3 (4 - 7) 8 9 1 3 8 (7 - 8) 2 1 1 2 (8 - 10) 3 2 should return an array for each: array1: 4 7 8 array2: 7 8 10 I am thinking of using split for each line, like line.split("("), but that doesn't quite doing the trick.. I was wondering if there is something more sophisticated for the job. Any help appreciated, Ted

  • Cucumber : Size of features

    - by David Lyod
    Im new to testing with cucumber and have a question regarding the size of a 'Feature'. Assume you can add a collection of items to a list and do the usual CRUD , is it preferred to create one feature for this complete set of CRUD actions or a feature for each? What is the preferred/accepted method ? At what point does an action become a feature itself ?

  • 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?

  • Using unless in rails uniqueness validation

    - by dunxd
    I am just starting out in Rails, and trying to develop a simple application. I need to validate three values submitted to the application - each must meet the same validation criteria. The validation is pretty simple: Value is valid if unqiue, null or equal to "p" or "d". The following gets me halfway there: validates_uniqueness_of :value1, :value2, :value3, :allow_nil => true I think I can use :unless to check whether the value is either "p" or "d", however I can't figure out how. I guess I am trying to combine validates_uniqueness_of with validates_inclusion_of. Any suggestions?

  • Best wrapper for simultaneous API requests?

    - by bluebit
    I am looking for the easiest, simplest way to access web APIs that return either JSON or XML, with concurrent requests. For example, I would like to call the twitter search API and return 5 pages of results at the same time (5 requests). The results should ideally be integrated and returned in one array of hashes. I have about 15 APIs that I will be using, and already have code to access them individually (using simple a NET HTTP request) and parse them, but I need to make these requests concurrent in the easiest way possible. Additionally, any error handling for JSON/XML parsing is a bonus.

  • 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]

  • ruby1.9.1 can't find installed gems, yet ruby1.8 can...

    - by Zombies
    On ubuntu here. I installed both ruby1.8 and ruby1.9.1. I also ran these commands ruby1.8 setup.rb ruby1.9.1 setup.rb Both worked fine, I was also able to install gems for both. The gems in gem 1.9.1 and gem1.8 both show up correctly for gem list. The problems however begin with this: ruby1.9.1 some_script.rb. It cannot find any of the gems. I tried uncommenting some out figuring that parseconfig was the problem, yet it couldn't find any of the others, which are definetly in gem1.9.1 list. Any thoughts as to what is causing this/how to recover?
