  • How to save http referer in rails

    - by TenJack
    I'm trying to save the site that a user came from when they sign up. Right now I have a before_filter in my ApplicationController: before_filter :save_referer def save_referer unless is_logged_in? session['referer'] = request.env["HTTP_REFERER"] unless session['referer'] end end Then when a user is created, it checks this session variable and sets it to nil. Sometimes this does not work and I'm worried there might be some unintended things happening with using session like this. Does anyone have a better way? Or some input perhaps? EDIT: This is the logic I am using to save the referer: def create @user = User.new(params[:user]) if @user.save_with(session[:referer]) .... end User def save_with(referer) self.referer = referer unless referer == "null" self.save end Is there any reason why this should not work?

  • when does factory girl create objects in db?

    - by Pavel K.
    i am trying to simulate a session using factory girl/shoulda (it worked with fixtures but i am having problems with using factories). i have following factories (user login and email both have 'unique' validations): Factory.define :user do |u| u.login 'quentin' u.email '[email protected]' end Factory.define :session_user, :class => Session do |u| u.association :user, :factory => :user u.session_id 'session_user' end and here's the test class MessagesControllerTest < ActionController::TestCase context "normal user" do setup do @request.session[:user_id]=Factory(:user).id @request.session[:session_id]=Factory(:session_user).session_id end should "be able to access new message creation" do get :new assert_response :success end end end but when i run "rake test:functionals", i get this test result 1) Error: test: normal user should be able to access new message creation. (MessagesControllerTest): ActiveRecord::RecordInvalid: Validation failed: Account name already exists!, Email already exists! which means that record already exists in db when i am referring to it in test setup. is there something i don't understand here? does factory girl create all factories in db on startup? rails 2.3.5/shoulda/factory girl

  • How do I add a condition to all ActiveRecords Queries for a particular model?

    - by Kyle West
    I am using the sentient_user gem to have access to the current_user object in my application. I want to override the default ActiveRecordBase queries to scope them to the current user. For instance, I don't want my users looking at, deleting, modifying other user's orders. I feel like I should be able to override a single (or couple) ActiveRecordBase methods to accomplish this, but I don't know which or how. Thanks in advance.

  • Mocking Sort With Mocha

    - by josephmate
    How can I mock an array's sort expect a lambda expression? This is a trivial example of my problem: # initializing the data l = lambda { |a,b| a <=> b } array = [ 1, 2, 3, 4, 5 ] sorted_array = [ 2, 3, 8, 9, 1] # I expect that sort will be called using the lambda as a parameter array.expects(:sort).with( l ).returns( sorted_array ) # perform the sort using the lambda expression temp = array.sort{|a,b| l.call(a,b) } Now, at first I expected that this would work; however, I got the following error: - expected exactly once, not yet invoked: [ 1, 2, 3, 4, 5 ].sort(#<Proc:0xb665eb48>) Is there a way to do what I am looking for? Cheers, Joseph

  • jQuery ajaxForm returning .json file

    - by Lowgain
    I've got a model creation form in rails which I also have returning JSON through ajax. My code so far look like: $('#new_stem').ajaxForm({ //#new_stem is my form dataType: 'json', success: formSuccess }); function formSuccess(stemObj) { //does stuff with stemObj } And I have a multipart form with a file uploader (but I'm not sure if that is relevant). When I submit the form it works fine (my models are properly being created and renders as json), but instead of the json getting handled by the formSuccess function, it prompts a download for "stems.json" (the path to my stem creation action) in Firefox. What would cause this to happen, and what could solve it? Not sure if this is part of the problem, but I don't have a submit button in my form, I have a link with a click handler that calls $('#new_stem).submit() Thanks guys!

  • Retrieving specific fixtures in Rails

    - by Bilal Aslam
    I have a YML file containing fixtures for a Rails model (Comment) which looks like this (pardon the formatting): comment_a: id: 1 text: 'foo' visible: false comment_b: id: 2 text: 'bar' visible: true comment_c: id: 3 text: 'baz' visible: true I know that I can select an individual Comment fixture like so: comments(:comment_a) In one of my acceptance tests, I want to find all the Comments which have visible = true. How do I select a set of Comments that meet certain criteria so I can iterate over them afterwards?

  • Regex issue with comma's telling me there are 6 args, instead of intended 4

    - by Azher
    I have a scenario outline table that looks like the following: Scenario Outline: Verify Full ad details Given I am on the xxx classified home page And I have entered <headline> in the search field & clicked on search When I click on full details Then I should see <headline> <year> <mileage> <price> displaying correctly and successfully Examples: |headline |year |mileage |price | |alfa romeo 166 |2005 |73,000 |6,990 | When I run my scenario it spits out that I have 6 args. But what I thought, I should only have 4 args: headline, year, mileage and price. I am thinking that it is taking the comma's and what is before and after it as two seperate args. Is there any way that I can make cucumber think that there are only 4 args with the example below? I have looked at messing around with regex but I dont seem to be getting anywhere. Any help would be greatly appreciated.

  • Why do you have to explicitly specify scope with friendly_id?

    - by nfm
    I'm using the friendly_id gem. I also have my routes nested: # config/routes.rb map.resources :users do |user| user.resources :events end So I have URLs like /users/nfm/events/birthday-2009. In my models, I want the event title to be scoped to the username, so that both nfm and mrmagoo can have events birthday-2009 without them being slugged. # app/models/event.rb def Event < ActiveRecord::Base has_friendly_id :title, :use_slug => true, :scope => :user belongs_to :user ... end I'm also using has_friendly_id :username in my User model. However, in my controller, I'm only pulling out events pertinent to the user who is logged in (current_user): def EventsController < ApplicationController def show @event = current_user.events.find(params[:id]) end ... end This doesn't work; I get the error ActiveRecord::RecordNotFound; expected scope but got none. # This works @event = current_user.events.find(params[:id], :scope => 'nfm') # This doesn't work, even though User has_friendly_id, so current_user.to_param _should_ return "nfm" @event = current_user.events.find(params[:id], :scope => current_user) # But this does work! @event = current_user.events.find(params[:id], :scope => current_user.to_param) SO, why do I need to explicitly specify :scope if I'm restricting it to current_user.events anyway? And why does current_user.to_param need to be called explicitly? Can I override this?

  • What is best strategy to handle exceptions & errors in Rails?

    - by Nick Gorbikoff
    Hello. I was wondering if people would share their best practices / strategies on handling exceptions & errors. Now I'm not asking when to throw an exception ( it has been throroughly answered here: SO: When to throw and Exception) . And I'm not using this for my application flow - but there are legitimate exceptions that happen all the time. For example the most popular one would be ActiveRecordNotFound. What would be the best way to handle it? The DRY way? Right now I'm doing a lot of checking within my controller so if Post.find(5) returns Nil - I check for that and throw a flash message. However while this is very granular - it's a bit cumbersome in a sense that I need to check for exceptions like that in every controller, while most of them are essentially the same and have to do with record not found or related records not found - such as either Post.find(5) not found or if you are trying to display comments related to post that doesn't exist, that would throw an exception (something like Post.find(5).comments[0].created_at) I know you can do something like this in ApplicationController and overwrite it later in a particular controller/method to get more granular support, however would that be a proper way to do it? class ApplicationController < ActionController::Base rescue_from ActiveRecord::RecordInvalid do |exception| render :action => (exception.record.new_record? ? :new : :edit) end end

  • Convert array of hashes to array of structs?

    - by keruilin
    Let's say I have two objects: User and Race. User has two attributes: first_name, last_name. And Race has three attributes: course, start_time, end_time. Now let's say I create an array of hashes like this: user_races = races.map{ |race| {:user = race.user, :race = race} } How do I then convert user_races into an array of structs, keeping in mind that I want to be able to access the attributes of both user and race from the struct element?

  • Rails XML Builder - Code refactoring

    - by Vijay Dev
    I have written the following code in my Rails app to generate XML. I am using Aptana IDE to do Rails development and the IDE shows a warning that the code structure is identical in both the blocks. What changes can be done to the code to remove the duplicity in structure?

  • Rails fields_for :child_index option explanation

    - by Timothy
    I have been trying to create a complex form with many nested models, and make it dynamic. Now I found that making a nested model isn't difficult with accepts_nested_attributes_for, but making it nested and dynamic was seemingly impossible if there were multiple nested models. I came across http://github.com/ryanb/complex-form-examples/blob/master/app/helpers/application_helper.rb which does it very elegantly. Could anyone shed some light on lines 13 and 16? 13 form_builder.object.class.reflect_on_association(method).klass.new and 16 form_builder.fields_for(method, options[:object], :child_index => "new_#{method}") do |f| From intuition, line 13 instantiates a new object, but why must it do so many method calls? I couldn't find any documentation for the :child_index option on line 16. When the form is created, a very large number is used as an index for new models, whereas existing models are indexed by their id. How does this work?

  • Authlogic OpenID: Fetching E-Mail from Provider.

    - by Shripad K
    This is a really weird problem: I have set up the authlogic_openid_selector_example app. When i register, the email id is not returned by the openid provider the first time. But if i delete the account and register again, the email id is returned. But this doesn't seem to be happening in the example hosted here: http://big-glow-mama.heroku.com/. How do i fix this problem? Has this got to do with caching? I have hosted my version of the app here: http://pingauthtest.heroku.com/ I guess the author of authlogic_openid_selector_example app (@holden) has forgotten to commit new changes. :) I looked at my development log and the first time the provider doesn't return the openid.ext1.value.ext0 which contains the email id. This is returned the second time only after having deleted the account first. Edit: This is some extra info for debugging: THIS IS WHEN IT REGISTERS: OpenIdAuthentication::Association Load (5.3ms) SELECT * FROM "open_id_authentication_associations" WHERE ("open_id_authentication_associations"."server_url" = E'https://www.google.com/accounts/o8/ud') Generated checkid_setup request to https://www.google.com/accounts/o8/ud with assocication AOQobUde_9BUnQsk91rb_Sf9tguJ-S7Gpkwahc-nvDGDYAC8nphisNqu Redirected to https://www.google.com/accounts/o8/ud? openid.assoc_handle=AOQobUde_9BUnQsk91rb_Sf9tguJ-S7Gpkwahc-nvDGDYAC8nphisNqu &openid.ax.mode=fetch_request &openid.ax.required=ext0 &openid.ax.type.ext0=http%3A%2F%2Faxschema.org%2Fcontact%2Femail &openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select &openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select &openid.mode=checkid_setup &openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0 &openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0 &openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1 &openid.realm=http%3A%2F%2Flocalhost%3A3000%2F &openid.return_to=http%3A%2F%2Flocalhost%3A3000%2Faccount%3Ffor_model%3D1%26_method%3Dpost%26open_id_complete%3D1 &openid.sreg.required=email Completed in 3574ms (DB: 14) | 302 Found [http://localhost/account] THIS IS WHEN IT USES SESSIONS: OpenIdAuthentication::Association Load (5.3ms) SELECT * FROM "open_id_authentication_associations" WHERE ("open_id_authentication_associations"."server_url" = E'https://www.google.com/accounts/o8/ud') Generated checkid_setup request to https://www.google.com/accounts/o8/ud with assocication AOQobUde_9BUnQsk91rb_Sf9tguJ-S7Gpkwahc-nvDGDYAC8nphisNqu Redirected to https://www.google.com/accounts/o8/ud? openid.assoc_handle=AOQobUde_9BUnQsk91rb_Sf9tguJ-S7Gpkwahc-nvDGDYAC8nphisNqu &openid.ax.mode=fetch_request &openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select &openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select &openid.mode=checkid_setup &openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0 &openid.ns.ax=http%3A%2F%2Fopenid.net%2Fsrv%2Fax%2F1.0 &openid.ns.sreg=http%3A%2F%2Fopenid.net%2Fextensions%2Fsreg%2F1.1 &openid.realm=http%3A%2F%2Flocalhost%3A3000%2F &openid.return_to=http%3A%2F%2Flocalhost%3A3000%2Fuser_session%3Ffor_session%3D1%26_method%3Dpost%26open_id_complete%3D1 Completed in 2708ms (DB: 15) | 302 Found [http://localhost/user_session]

  • Issues with Rails, Amazon S3, and protected URLs

    - by Shpigford
    So I followed this little tutorial about protecting downloads of files that are uploaded to Amazon S3 with Paperclip. When I've developed locally, it's worked fine, but since pushing the exact same code to a production server...I now get this error from Amazon when I try to access the files: <Error> <Code>InvalidArgument</Code> <Message>Either the Signature query string parameter or the Authorization header should be specified, not both</Message> <ArgumentValue>Basic dGVjaHVrdWxlbGU6ZWxlbHVrdWhjZXQ=</ArgumentValue> <ArgumentName>Authorization</ArgumentName> <RequestId>F6E455857C54F95A</RequestId> <HostId>X4QA2pw9wpHtJtJ2T8qxCyINjq4PLHQVF4VrlYjpX7Ayh694BgQprh5p8H7NRCAt</HostId> </Error> Example URL: http://s3.amazonaws.com/media.example.com/assets/videos/1/original.mov?AWSAccessKeyId=MY_ACCESS_KEY&Expires=1271972624&Signature=7wWH2WYHPO0o9szwPJbimUMqAig%3D That URL is generated using AWS::S3::S3Object.url_for using the aws-s3 gem. So...not even sure where to start. The fact that it works fine when the app is running locally but not when in production really doesn't make sense. The production server is running Ubuntu 8.04.4 LTS (Hardy).

  • FileUtils.mv adding linebreaks in Windows

    - by Lowgain
    I am streaming wav data from a flash application. If I get the data and do the following: f = File.open('c:/test.wav') f << wav_data.pack('c'*wav_data.length) f.close The wav file works perfectly. If I do this: f = Tempfile.new('test.wav') f << wav_data.pack('c'*wav_data.length) f.close FileUtils.mv(f.path, 'c:/') The file is there, but sounds all garbled. Checking in a hex editor shows that everywhere the working file had an 0A (or \n), the garbled version had 0D0A (or \r\n) I am using this in conjuction with rails+paperclip, and am going to be using a combination of Heroku and S3 for the live app, so I am hoping this problem will solve itself, but I'd like to get this working on my local machine for the time being. Does anybody know of any reason FileUtils.mv would be doing this, and if there is a way to change its behaviour?

  • RSpec mocking a nested model in Rails - ActionController problem

    - by emson
    Hi All I am having a problem in RSpec when my mock object is asked for a URL by the ActionController. The URL is a Mock one and not a correct resource URL. I am running RSpec 1.3.0 and Rails 2.3.5 Basically I have two models. Where a subject has many notes. class Subject < ActiveRecord::Base validates_presence_of :title has_many :notes end class Note < ActiveRecord::Base validates_presence_of :title belongs_to :subject end My routes.rb file nests these two resources as such: ActionController::Routing::Routes.draw do |map| map.resources :subjects, :has_many => :notes end The NotesController.rb file looks like this: class NotesController < ApplicationController # POST /notes # POST /notes.xml def create @subject = Subject.find(params[:subject_id]) @note = @subject.notes.create!(params[:note]) respond_to do |format| format.html { redirect_to(@subject) } end end end Finally this is my RSpec spec which should simply post my mocked objects to the NotesController and be executed... which it does: it "should create note and redirect to subject without javascript" do # usual rails controller test setup here subject = mock(Subject) Subject.stub(:find).and_return(subject) notes_proxy = mock('association proxy', { "create!" => Note.new }) subject.stub(:notes).and_return(notes_proxy) post :create, :subject_id => subject, :note => { :title => 'note title', :body => 'note body' } end The problem is that when the RSpec post method is called. The NotesController correctly handles the Mock Subject object, and create! the new Note object. However when the NoteController#Create method tries to redirect_to I get the following error: NoMethodError in 'NotesController should create note and redirect to subject without javascript' undefined method `spec_mocks_mock_url' for #<NotesController:0x1034495b8> Now this is caused by a bit of Rails trickery that passes an ActiveRecord object (@subject, in our case, which isn't ActiveRecord but a Mock object), eventually to url_for who passes all the options to the Rails' Routing, which then determines the URL. My question is how can I mock Subject so that the correct options are passed so that I my test passes. I've tried passing in :controller = 'subjects' options but no joy. Is there some other way of doing this? Thanks...
