This has taken my whole day...
I am getting the following error:
uninitialized constant User::Rssfeed
Extracted source (around line #7):
4: <p>You have no feeds chosen</p>
5: <p>Select Feeds</p>
6: <%= #user.id %>
7: <%= form_for ([#user, #user.rssfeeds.build]) do |f| %>
8:
9: <%= f.label :URL %>
10: <%= f.text_field :url %>
These are my files:
routes.rb
PracticeApp::Application.routes.draw do
devise_for :users do
resources :rssfeeds
end
...
user.rb
class User < ActiveRecord::Base
# Include default devise modules. Others available are:

end
rss_feed.rb
class RssFeed < ActiveRecord::Base
belongs_to :user

I am posting my full Trace after the below comment
I hope this is only the stack trace:

because you've said that a user has many :rssfeeds, it is expecting a class called Rssfeed and you have one called RssFeed.
Two options:
Change the class to Rssfeed:
class RssFeed < ActiveRecord::Base
belongs_to :user
attr_accessible :title, :url, :user_id
end
Or change the association:
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
has_many :rss_feeds
end
<p>You have no feeds chosen</p>
5: <p>Select Feeds</p>
6: <%= #user.id %>
7: <%= form_for ([#user, #user.rss_feeds.build]) do |f| %>
8:
9: <%= f.label :URL %>
10: <%= f.text_field :url %>

I'm developing a system to improve my Rails skills, which will allow anyone to create a user. This user will have an inventory, which will contain multiple items.
My question is how can I store all the resources when saving a new user. I'm trying to use cocoon gem, and I got this error message:
undefined method `new_record?' for nil:NilClass
at this part of the code:
<%= link_to_remove_association "remove item", f %>
Models
class User < ActiveRecord::Base
has_one :inventory
delegate :items, to: :inventory, prefix: true
accepts_nested_attributes_for :inventory
end
class Inventory < ActiveRecord::Base
has_many :inventory_items
has_many :items, through: :inventory_items
accepts_nested_attributes_for :inventory_items, reject_if: :all_blank, allow_destroy: true
end
class InventoryItem < ActiveRecord::Base
belongs_to :item
belongs_to :inventory
end
Controller
class UsersController < ApplicationController
def new
#user = User.new.tap do |user|
user.inventory = Inventory.new
user.inventory_items.build
end
end
private
def user_params
params
.require(:user)
.permit(
:name,
:lat,
:long,
:age,
inventory_attributes: [:id, inventory_items_attributes: [:quantity, :inventory_id, :item_id, :_destroy]]
)
end
end
User form
<%= simple_form_for(#user) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :name %>
<%= f.input :lat %>
<%= f.input :long %>
</div>
<h3>Items</h3>
<div id="inventory_items">
<%= f.simple_fields_for :inventory do |inventory| %>
<%= inventory.simple_fields_for :inventory_items do |f| %>
<%= render 'item_fields', f: f %>
<% end %>
<% end %>
</div>
<div class="form-actions">
<%= f.button :submit %>
</div>
<% end %>
item_fields partial
<div class="nested-fields">
<%= f.collection_select :item_id, Item.all, :id, :name %>
<%= f.input :quantity %>
<%= link_to_remove_association "remove item", f %>
</div>
The inventory does not have more attributes than its id and user_id

In an exercise, I'm trying to create authorization such that a user needs to be either the post's owner or the general administrator, on top of being present and logged-in to update a post. I am trying to implement a pundit policy (using Devise for authentication).
The PostController Class:
class PostsController < ApplicationController
...
def edit
#post = Post.find(params[:id])
authorize #post
end
...
end
The ApplicationPolicy Class:
class ApplicationPolicy
attr_reader :user, :record
def initialize(user, record)
#user = user
#record = record
end
...
def update?
user.present? && (record.user == user || user.role?(:admin))
end
def edit?
update?
end
def destroy?
update?
end
...
end
* The User model* :
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :confirmable
has_many :posts
def role?(base_role)
role == base_role.to_s
end
end
I got stuck with the Argument Error: wrong number of arguments (2 for 1). My understanding is that the policy method is part of the Pundit module, and it initializes and returns a new policy object with the given record and current_user as the implicit user. Can someone help me shed a light into this issue?
ERROR MESSAGE:

The first 2-3 lines of the error trace tell us the problem is in ApplicationPolicy#update? and User#role?:
activerecord (4.0.10) lib/active_record/attribute_methods/query.rb:35:in attribute?'
activemodel (4.0.10) lib/active_model/attribute_methods.rb:383:in role?'
app/policies/application_policy.rb:26:in update?'
Looking at the code in question:
class ApplicationPolicy
...
def update?
user.present? && (record.user == user || user.role?(:admin))
end
...
end
Here's a few things to try:
Check User has a role? method defined on it.
Check User#role? is being found and called. Insert logging or a raise "In User#role?" statement into the method to be certain.
Ensure db migrations have run on development and test environments by running the rake db:migrate and rake db:migrate RAILS_ENV=test tasks.
Restart the server rails s
The association method from simple_form is throwing an exception on the most basic use, and I cannot figure out why. I'd appreciate any help.
I have a has_and_belongs_to_many association between the Users and Projects models:
project.rb:
class Project < ActiveRecord::Base
has_and_belongs_to_many :users
belongs_to :owner, :class_name => "User", :foreign_key => "owner_id"
...
user.rb:
class User < ActiveRecord::Base
has_and_belongs_to_many :projects
has_many :projects_owned, :class_name => "Project", :foreign_key => "owner_id"
...
edit.html.erb:
<%= simple_form_for #project do |f| %>
<%= f.input :name, input_html: { size: 61 } %>
<%= f.input :description, as: :text, input_html: { cols: 60 } %>
<%= f.association(:users) %>
<%= f.submit "Save project", class: "btn btn-large btn-primary" %>
<% end %>
All models have corresponding tables, and the association works correclty in Rspec tests and the Rails console.
When I build the form, exactly as specified in the simple_form documentation, I get the following error:
<ArgumentError: wrong number of arguments (0 for 1)>

The problem has something to do with the collection for the form field.
See if this works:
<%= f.association :users, collection: User.all %>
I haven't tracked down why the collection is needed yet, but that seems to be the problem.
I get the errors message in the title and I can't understand why?
this my code
user.rb
has_one :GoldBook
has_many :comments
gold_book.rb
has_many :comments
belongs_to :user
comment.rb
belongs_to :user
belongs_to :gold_book
comments_controller.rb
def create
#gold_book = GoldBook.find(params[:gold_book_id])
#comment = Comment.new(params[:comment])
#comment.goldbook = #gold_book
#comment.user = current_user
gold_books/show.html.erb
<%= render 'goldbook' %>
gold_books/_goldbooks
<%= render 'comments/form', goldbook: goldbook %>
comments/_form
<%= form_for([goldbook, #comment]) do |f| %>
<% if #comment.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#comment.errors.count, "error") %> prohibited this comment from being saved:</h2>
<ul>
<% #comment.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :content %><br />
<%= f.text_area :content %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
I think the error is in the comments' form but not sure ...
I'm trying to make somethink like a gold book with many comment

Associations are case-sensitive. Change this:
has_one :GoldBook
to
has_one :gold_book
Also, your instance variable is called #gold_book, but in your show view you're referring to goldbook. Try changing it to:
<%= render 'comments/form', gold_book: #gold_book %>
In general, make sure you adhere to the naming conventions of Rails. Take a look at this guide, particularly the section on "Rendering by default".
I'm having problem with form_for, have searched for the problem for the solutions given does not solve my problem.
I'm trying to do up a form to create new recipes:
**app/views/recipes/new.html.erb**
<%= form_for #recipe do |f| %>
<% if #recipe.errors.any? %>
<% end %>
<div class="field">
<%= f.label :recipename %><br />
<%= f.text_area :recipename %>
</div>
<div class="field">
<%= f.label :user_id %><br />
<%= f.number_field :user_id %>
</div>
<div class="actions">
<%= f.submit %>
</div>
**routes.rb**
Baserecipe::Application.routes.draw do
resources :users
resources :recipes
....
match '/createrecipe', to: 'recipes#new'
**recipes_controller.rb**
class RecipesController < ApplicationController
def create
#recipe = Recipe.new(params[:recipe])
end
end
I'm alway getting the error:
