similar to: NilClass passed to partial view

Hi guys, I just started using Ruby on Rails. After implementing the RoR blog tutorial I started with my own data model. Sadly I am not able to get my create page running. Model: class Activity < ActiveRecord::Base validates :activity, :presence => true validates :forKids, :presence => true validates :start_date, :presence => true end Controller: class ActivitiesController <

I''ve been searching the web, wikis, and more, and I haven''t turned up examples of how to have multiple entities in a single-table inheritance related to anything. I have an addresses table, but multiple entities can have Addresses: both Person (which has 2 addresses) and Retailer. I''ve been told that I need to use single-table inheritance, and this was my attempt:

Hi All, just in a spot of bother with this gem, I am trying to create a new location and get the above msg. here is my controller: class LocationsController < ApplicationController # GET /locations # GET /locations.json def index @locations = Location.all @json = Location.all.to_gmaps4rails end respond_to do |format| format.html # index.html.erb

Hi! I know that there are other topics about this issue, I read them and I''m always blocked. Here is the error message: undefined method `model_name'' for NilClass:Class Extracted source (around line #30): 27: 28: <h2>Add Translation</h2> 29: 30: <%= form_for @new_trad do |f| %> 31: Locale: <%= f.text_field :locale %> 32: Key : <%=

Hi, How do I relate a table to another when one of the models uses single table inheritance? Will this even work? This is the specific problem I am having: There''s an "Address" model with "ShippingAddress" and "BillingAddress" as subclasses. It looks like this: class Address < ActiveRecord::Base End class ShippingAddress < Address has_one :order

I am new to Ruby on Rails and have a very simple foreign key example that is driving me nuts. I am using Rails 3 under Windows Vista and have two tables: users and user_comments. user_comments.user_id should point to the user a comment is about. In my show view for user I have a link to the new method of user_comments to allow a comment to be created. This throws: Showing

Hi there I''m in the process of developing an e-commerce Rails app but am getting a little stuck on what models I should be working with on the order/checkout side of things. The app requires users to be registered and authenticated to checkout. So I already have a User model and an Order model (which belongs to a User). The Order model is largely similar to that used in the Agile Rails

This is really a git question but the problem is with rails using git and others may have come across the problem. I have a branch on my application''s git repository with edge rails as a subproject checked out into vendor/rails. this allows me to keep my application edge-compliant by checking out the branch (which creates the rails folder in vendor), pulling the latest edge rails and

class BranchesController < ApplicationController def branch @branch = Branch.new (params[:branch]) branch_back = @branch.*branch* end end in the model have one *branch.rb* class Branch def branch end end In the view have one branches folder, also have the branch.html.erb in that folder. <%= form_for(@branch) do |f| %> <%end%> *routes.rb* * * match

Im new to Rails, and decided to start of with Rails3. After a lot of searching ive managed to get a little bit of Authlogic working. I''m able to register a user, login & logout. Now, I would like to add more features, get more of authlogic working. I''m using Railscast EP 160 as my reference. Portions of the code found on the tutorial throw errors: Eg: <!--

I have been working on a project based on Michael Hartl''s book Ruby on Rails Tutorial in order to try to teach myself Ruby on Rails. However, when it tries to render a form designed to allow a user to submit a small message, I get an error saying, "undefined method `model_name'' for NilClass:Class". It says the error is at line 1, which is "<%= form_for

Hello all, I''m getting this weird ''<input name value=''2'' type=''hidden'' />'' text printed out in my form. See attached image. I''ve spent too much time trying to figure it out already and it''s not going to stop me from moving on for now. As you can see it''s still very early on. I''m using

In my user_sessions_controller: class UserSessionsController < ApplicationController before_filter :require_no_user, :only => [:create, :new] before_filter :require_user, :only => :destroy def new @user_session = UserSession.new @message = "Hello." end def create @user_session = UserSession.new(params[:user_session]) if @user_session.save

I''m walking through an example in the "Head First Rails" book, but, instead doing the examples using Rails3.0.0.rc. But, I''m getting this error when browsing for example: http://localhost:3000/advs/1 undefined method `eq'' for nil:NilClass Provided that my advs_controller.rb is as follows: http://pastie.org/private/cd9zntg2ite57ept288kfa Any ideas why

hi i am using rails 2.3.4 and i am facing "no method error" there is possibility to not find method but my question is - is there possibility to error occurred because of empty table? or error in another controller or helper? error trace: Processing QuoteRequestsController#create (for 127.0.0.1 at 2012-10-17 16:07:34) [POST] Parameters:
