• rails separate login for an api

  - by Squadrons

  I have a very simple api that is part of a rails app that requires logging in. I just need a way to make the api part accessible with a simple form that allows the user to enter parameters like a key (just a simple one stored in the DB, no OAuth or anything), a userId to find and return a user via json, and maybe some other parameters like asking for their schedule. How can I keep this seperate from the rest of the app, making it a public facing form that will grant access only to the api? Thanks.

• Reloading an object not working in rspec

  - by Eric Baldwin

  I am trying to test a controller method with the following code: it "should set an approved_at date and email the campaign's client" do @campaign = Campaign.create(valid_attributes) post :approve, id: @campaign.id.to_s @campaign.reload @campaign.approved_at.should_not be(nil) end However, when I run this test, I get the following error: Failure/Error: @campaign.reload ActiveRecord::RecordNotFound: Couldn't find Campaign without an ID When I run the analagous lines in the rails console, the reload works and the value is set as I need it to be. Why isn't reload working for me when I run the code in an rspec test?

• Rails routing aliasing and namespaces

  - by kain

  Given a simple namespaced route map.namespace :api do |api| api.resources :genres end how can I reuse this block but with another namespace? Currently I'm achieving that by writing another routes hacked on the fly map.with_options :name_prefix => 'mobile_', :path_prefix => 'mobile' do |mobile| mobile.resources :genres, :controller => 'api/genres' end But it seems less than ideal.

• Calculate difference in days ActiveSupport:TimeWithZone in the most "rubyish" style?

  - by Nick

  I have a feeling someone is going to point me to another question that answers this but I've been searching with no luck over this simple issue. I have a Activerecord with a datetime property. It returns as an ActiveSupport:TimeWithZone. I know I can't compare that to DateTime.now because that doesn't include a zone so I need to use Time.zone. Makes sense. What I'm wondering is stylewise is there a "cleaner" way to do this than subtracting and dividing the result by 86400? Here's what I do: ((Time.zone.now - myActiveRecord.visit_date)/86400).to_i Works but seems un-rubyish and I feel like I'm missing something. Should I be casting, comparing or converting some other route or is this really the typical way to do this in rails? Appreciate any tips or a link to a question that already covers this. Thank you

• Rails log management

  - by ambertch

  I'm starting to get overwhelmed using VI to search through my logs to chase down login errors and would like a better solution. I know Newrelic is highly recommended, though was wondering if there was something free I could try for the short term. Thanks!

• Getting the image URL without the HTML in Rails

  - by tesmar

  Hi, In Rails is there a way to get the URL to the image (going through the assets_host) and just return the URL of the image? I want to use assets_host data in my Javascript, but I just need to insert the URL into the JS, not the whole image_tag. Thank you in advance!

• Is it possible to route heroku-rails-app to a subdirectory of my custom domain?

  - by ernd enson

  I want to setup a rails app on heroku that is part of a website. The website which is hosted on a different server explains the usage of the app, shows a tour, plans, contains a blog on related stuff and so on. I want to route to my_domain/app and the app should respond to that url. The custom_domain add-on doesnt allow to enter directories. How can I configure that or how would you realize that scenario?

• Twitter + Grackle, determining the logged in user

  - by JP

  This is crazy, but I'm stumped! Once my user has logged into twitter via OAuth how do I determine their username using grackle? @twitter = Grackle::Client.new(:auth => { :type => :oauth, :consumer_key => consumer_key, :consumer_secret => consumer_secret, :token => @access_token.token, :token_secret => @access_token.secret }) username = @twitte.something_here?

• Sorting page flow for has_many in Rails

  - by Gareth

  I have a page flow allowing the user to choose an object ("Player") to add to a has_many :players association in another model. 1 => List existing players for object [Enter player name] 2 => List of matching players [Select player] 3 => Confirmation page [Press 'Add'] 4 => Done I want users to be able to choose "New Player" instead of selecting a player at step 2, in which case the user will go through the standard New Player process elsewhere on the site. However, after that's done, the user should return to step 3 with the new player in place. I don't know what the best way is to implement this. I don't want to duplicate the player creation code, but I don't want to dirty up the player creation code too much just for this case. I also don't want to start sticking IDs in the session if I can help it. It's fine in simple cases but if the user ever has two windows/tabs then things start behaving badly. What do you think?

• Adding validations without knowing the fields

  - by Frexuz

  My example form <% form_for @ad do |f| %> <%= f.error_messages %> <p> <%= f.label :ad_type_id %><br /> <%= f.collection_select(:ad_type_id, AdType.all, :id, :name) %> </p> <p> <% @ad.ad_properties.each do |property| %> <%= property.name %>: <% f.fields_for :ad_values do |value_field| %> <%= value_field.text_field :ad_id, :value => @ad.id %> <%= value_field.text_field :ad_property_id, :value => property.id %> <%= value_field.text_field :value %> <% end %><br /><br /> <% end %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p><%= f.submit %></p> <% end %> Explanation: Ad has many properties. I can add new properties at any time (it's a normal model). Lets say the Ad is of the type 'hotel'. Then I would add properties like 'stars' and 'breakfast_included' Then I store each of these properties' values in a separate model. And all this works fine with my form above. My problem: These fields are not validated because I can't know what their names are. I need to add validations dynamically somehow. My thought: #Before the normal validations kick in def add_validations self.properties.each do |property| property.add_validation :whatever #somehow :) end end How could I do this?

• Can i get RSpec to generate specs with expect syntax?

  - by papirtiger

  When generating specs with : rails g controller Home index A spec is generated with the older object.should syntax require 'spec_helper' describe HomeController do describe "GET 'index'" do it "returns http success" do get 'index' response.should be_success end end end Is it possible to configure the generator to use the expect syntax instead? Desired output: require 'spec_helper' describe HomeController do describe "GET 'index'" do it "returns http success" do get 'index' expect(response).to be_success end end end in config/application.rb: config.generators do |g| g.test_framework :rspec, fixture: true g.fixture_replacement :factory_girl, dir: 'spec/factories' g.view_specs false g.stylesheets = false g.javascripts = false end

• Rails 3 refactoring issue

  - by Craig

  The following view code generates a series of links with totals (as expected): <% @jobs.group_by(&:employer_name).sort.each do |employer, jobs| %> <%= link_to employer, jobs_path() %> <%= "(#{jobs.length})" %> <% end %> However, when I refactor the view's code and move the logic to a helper, the code doesn't work as expect. view: <%= employer_filter(@jobs_clone) %> helper: def employer_filter(jobs) jobs.group_by(&:employer_name).sort.each do |employer,jobs| link_to employer, jobs_path() end end The following output is generated: <Job:0x10342e628>#<Job:0x10342e588>#<Job:0x10342e2e0>Employer A#<Job:0x10342e1c8>Employer B#<Job:0x10342e0d8>Employer C#<Job:0x10342ded0>Employer D# What am I not understanding? At first blush, the code seems to be equivalent.

• join same rails models twice, eg people has_many clubs through membership AND people has_many clubs through committee

  - by Ben

  Models: * Person * Club Relationships * Membership * Committee People should be able to join a club (Membership) People should be able to be on the board of a club (Committee) For my application these involve vastly different features, so I would prefer not to use a flag to set (is_board_member) or similar. I find myself wanting to write: People has_many :clubs :through = :membership # :as = :member? :foreign_key = :member_id? has_many :clubs :through = :committee # as (above) but I'm not really sure how to stitch this together

• Rails: i would need to load a haml file in a class and render in the caller

  - by Totty

  I have this: app/modules/grid_module.rb app/modules/grid.html.haml then in my view: app/views/layouts/default.html.haml I want to make a new instance of the grid_module and render it content. Its content is into the grid.html.haml and this file can only use the instance vars set in the grid_module.rb is this possible to do? (the grid name is just an example, it must be more flexible, to load the html.haml file based on the .rb class) the grid_module must has access to models too* like this: User.find_by_id(4) thanks for help

  I am trying to mock a view helper with rspec2. The old way of doing this throws an error, complaining the template object is not defined: template.should_receive(:current_user).and_return(mock("user")) Am I missing something here, or is this not implemented in rspec2 (yet)?

• Double join with habtm in ActiveRecord

  - by Daniel Huckstep

  I have a weird situation involving the need of a double inner join. I have tried the query I need, I just don't know how to make rails do it. The Data Account (has_many :sites) Site (habtm :users, belongs_to :account) User (habtm :sites) Ignore that they are habtm or whatever, I can make them habtm or has_many :through. I want to be able to do @user.accounts or @account.users Then of course I should be able to do @user.accounts < @some_other_account And then have @user.sites include all the sites from @some_other_account. I've fiddled with habtm and has_many :through but can't get it to do what I want. Basically I need to end up with a query like this (copied from phpmyadmin. Tested and works): SELECT accounts.* FROM accounts INNER JOIN sites ON sites.account_id = accounts.id INNER JOIN user_sites ON sites.id = user_sites.site_id WHERE user_sites.user_id = 2 Can I do this? Is it even a good idea to have this double join? I am assuming it would work better if users had the association with accounts to begin with, and then worry about getting @user.sites instead, but it works better for many other things if it is kept the way it is (users <- sites).

• Creating has_many relationships in ActiveRecord without :primary_key

  - by kmorris511

  I'm working with an older version of Rails and ActiveRecord that does not have the :primary_key option in has_many relationships of more recent ActiveRecord versions and unfortunately I don't get to control when we upgrade. Is there any way to hack this solution via :conditions or :finder_sql options?

• How can I dynamically define the named route in a :partial in rails?

  - by Angela

  I have the following partial. It can be called from three different times in a view as follows: <%= render :partial => "contact_event", :collection => @contacts, :locals => {:event => email} %> Second time: <%= render :partial => "contact_event", :collection => @contacts, :locals => {:event => call} %> Third time: <%= render :partial => "contact_event", :collection => @contacts, :locals => {:event => letter} %> In each instance, call, email, letter refer to a specific instance of a Model Call, Email, or Letter. Here is the content of the partial "contact_event": <%= link_to_remote "Skip #{event} Remote", :url => skip_contact_email_url(contact_event, event), :update => "update-area-#{contact_event.id}-#{event.id}" %> <span id='update-area-<%="#{contact_event.id}-#{event.id}"%>'> </span> </p> My challenge: skip_contact_email_url only works when the event refers to an email. How can I dynamically define skip_contact_email_url to be skip_contact_letter_url if the local variable is letter? Even better, how can I have a single named route that would do the appropriate action?
