routes.rb:
resources :shops
shop_controller.rb:
def new
#shop=Shop.new
end
new.html.erb:
<%= form_for(#shop) do |f| %>
....
<% end %>
error:
undefined method `shops_path' for:
<%= form_for(#shop) do |f| %>
The problem is that I already specify the shop resources in the routes file.
Why still get such kind of error?
Any help will be appreciated, thanks
You should use ShopsController not ShopController due to Rails naming convention.
Make sure you have these lines in your rake routes output:
shops GET /shops(.:format {:action=>"index", :controller=>"shops"}
POST /shops(.:format) {:action=>"create", :controller=>"shops"}
OR
shops POST /shops(.:format) {:action=>"create", :controller=>"shops"}
If they aren't present, look carefully at your routes.rb for possible with_options, scope or any other scoping that can affect your resources :shops in such a way that it doesn't generate default url helpers.
since u havent specified the method in the form tag, i guess it is going as a GET request. Try adding the method to ur form
<%= form_for(#shop), :method => :post do |f| %>

I get the error
undefined method `favorite_relationships_path'
when I display this form:
<%= form_for(current_user.favorite_relationships.build(lesson_id: #lesson.id),
remote: true) do |f| %>
<div><%= f.hidden_field :lesson_id %></div>
<%= f.submit "Favorite", class: "btn btn-large btn-primary" %>
<% end %>
I'm not sure why. I have a controller called favorite_relationships_controller.rb and a model file, favorite_relationship.rb, with the code
class FavoriteRelationship < ActiveRecord::Base
attr_accessible :lesson_id
belongs_to :user
belongs_to :lesson
end
My user model also has:
has_many :favorite_relationships
has_many :lessons, :through => :favorite_relationships
I'm really not sure why im getting that error. Help would be appreciated.
Rails has _path and _url helpers for routes, which are set up in config/routes.rb. You'll need to ensure that you've defined the routes for FavouriteRelationshipController; something like:
resources :favourite_relationships
You can check the routes defined for your application using the rake routes command.
You can find more information about routing at the Rails Routing from the Outside In guide.
Defining controllers, actions and views is not enough. You need to define routes in config/routes.rb to connect URLs to your controllers/actions. Defining RESTful resources with resources :favourite_relationships in your routing file is what causes Rails to generate the *_path and *_url helpers; until you do this there is no way for requests to reach your app, and no way for your app to generate routes based on your models.
Your routes file should look something like this:
MyApp::Application.routes.draw do
resources :favourite_relationships
end
This generates the typical "CRUD" routes required for a RESTful resource:
favourite_relationships GET /favourite_relationships(.:format) {:action=>"index", :controller=>"favourite_relationships"}
POST /favourite_relationships(.:format) {:action=>"create", :controller=>"favourite_relationships"}
new_favourite_relationship GET /favourite_relationships/new(.:format) {:action=>"new", :controller=>"favourite_relationships"}
edit_favourite_relationship GET /favourite_relationships/:id/edit(.:format) {:action=>"edit", :controller=>"favourite_relationships"}
favourite_relationship GET /favourite_relationships/:id(.:format) {:action=>"show", :controller=>"favourite_relationships"}
PUT /favourite_relationships/:id(.:format) {:action=>"update", :controller=>"favourite_relationships"}
DELETE /favourite_relationships/:id(.:format) {:action=>"destroy", :controller=>"favourite_relationships"}
This is my route:
scope ":username" do
resources :feedbacks
end
I am on my home/index.html.erb view and I am trying to do this:
<%= render "feedbacks/form" %>
But this gives me this error:
ActionView::Template::Error (No route matches {:controller=>"feedbacks", :format=>nil}):
1: <%= form_for(#feedback) do |f| %>
2: <% if #feedback.errors.any? %>
3: <div id="error_explanation">
4: <h2><%= pluralize(#feedback.errors.count, "error") %> prohibited this feedback from being saved:</h2>
app/views/feedbacks/_form.html.erb:1:in `_app_views_feedbacks__form_html_erb__3181571289116259961_2487495480'
app/views/home/index.html.erb:18:in `_app_views_home_index_html_erb___397233383548615486_2487321620'
This is my rake routes for feedbacks:
feedbacks GET /:username/feedbacks(.:format) {:action=>"index", :controller=>"feedbacks"}
POST /:username/feedbacks(.:format) {:action=>"create", :controller=>"feedbacks"}
new_feedback GET /:username/feedbacks/new(.:format) {:action=>"new", :controller=>"feedbacks"}
edit_feedback GET /:username/feedbacks/:id/edit(.:format) {:action=>"edit", :controller=>"feedbacks"}
feedback GET /:username/feedbacks/:id(.:format) {:action=>"show", :controller=>"feedbacks"}
PUT /:username/feedbacks/:id(.:format) {:action=>"update", :controller=>"feedbacks"}
DELETE /:username/feedbacks/:id(.:format) {:action=>"destroy", :controller=>"feedbacks"}
Edit 1
When I pass in the local instance variable #feedback like this: <%= render "feedbacks/form", :local => #feedback %> which is pulling from my home controller, where it is declared like this:
class HomeController < ApplicationController
def index
#users = User.all
#feedback = Feedback.new
end
end
I still get this error:
Routing Error
No route matches {:controller=>"feedbacks", :format=>nil}
Edit 2
I also have a users resource specified in my routes file, that looks like this:
resources :users
scope ":username" do
resources :feedbacks
end
Seems like form_for can't find the correct route, this line suggests you don't have an instance variable #feedback set when trying to render that partial:
(No route matches {:controller=>"feedbacks", :format=>nil})
Notice there is no :id parameter in that hash (which is likely being passed to the router to generate the correct URL to submit the form to).
Do you define a #feedback somewhere in the controller action (preferable) or views you're using? If you think you are, try the following above line 1 of your partial:
logger.info "feedback object: #{#feedback.inspect}"
Edit:
First of all, locals should be passed not as :local => #feedback but as:
:locals => {:variable_name_in_partial => value_for_variable_name}
Second of all, you are trying to access #feedback which is an instance variable accessible to views even if it's not passed explicitly (as long as it's set). So as long as you set it in the HomeController#index method you don't need to pass it to any views locally.
Also, you are not using the correct syntax for rendering partials (wish I had noticed earlier!).
Change the following:
<%= render "feedbacks/form" %>
To this:
<%= render :partial => "feedbacks/form" %>
Aren't you forgetting to pass in :username? Your route says scope :username
If I add a route like yours, open up the Rails console, include Rails.application.routes.url_helpers and run feedbacks_path, I get a routing error, but feedbacks_path :username => 'bob' works fine.
> feedbacks_path(:username => 'bob')
=> "/bob/feedbacks"
Are you sure you want scope? What about a nested resource as per:
resources :users do
resources :feedbacks
end
Also, I've had trouble when using controllers with plural names. You might try renaming FeedbacksController to FeedbackController.
routes.rb:
resources :jobs do
resources :activitylogs
end
rake routes:
...
POST /jobs/:job_id/activitylogs(.:format) {:controller=>"activitylogs", :action=>"create"}
new_job_activitylog GET /jobs/:job_id/activitylogs/new(.:format) {:controller=>"activitylogs", :action=>"new"}
edit_job_activitylog GET /jobs/:job_id/activitylogs/:id/edit(.:format) {:controller=>"activitylogs", :action=>"edit"}
...
How do I use the route new_job_activitylog?
Doing <%= new_job_activitylog %> gives undefined exception - so does using link_to which most of the examples I see are using.
Use
<%= new_job_activitylog_path %>
or
<%= new_job_activitylog_url %>
_path returns a relative path, while _url returns a complete url including http://domain.com if you've set it in your config.
To use those route names, I just had to append _path to them.
So: new_job_activitylog is undefined, but new_job_activitylog_path is a method in the view that takes the job id as a parameter.
<%= link_to 'new', new_job_activitylog_path(:job_id => #job.id) %>
works!
In my application, I have a RecipesController and a CommentsController. All comments belong to a recipe, and can be voted up. Here's a snippet from my routes.rb:
resources :recipes do
member do
put 'vote_up'
post 'comment'
end
resources :comments do
member do
put 'vote_up'
end
end
end
If I run rake routes, I find the following route in the output:
vote_up_recipe_comment PUT /recipes/:recipe_id/comments/:id/vote_up(.:format) {:action=>"vote_up", :controller=>"comments"}
The CommentsController has a method called vote_up.
Also, linking to the route works (from my view)
<%= link_to 'Vote up', vote_up_recipe_comment_path(#recipe, comment), :method => 'put' %> <br />
However, clicking on that link gives me the following error:
Routing Error
No route matches "/recipes/7/comments/4/vote_up"
What am I missing? I'm not sure how to debug this, because as far as I can see the route should match.
I think that you get this error message because the request is made via HTTP GET method, not PUT.
In order to create links that use POST/PUT/DELETE method, your application should correctly load a Javascript Rails adapter.
Check that your app has jQuery (http://github.com/rails/jquery-ujs) or Prototype JS adapter and that your layout correctly loads it.
try the following tweak: send the put method as a symbol
<%= link_to 'Vote up', vote_up_recipe_comment_path(#recipe, comment), :method => :put %>
so i've got a model class named Photoset and a controller named Sets.
ive got resources :sets working for everything except when paths are generated off an instance of the model. for example if i use:
<%= form_for(#photoset) do |f| %>
i get the error:
no route matches {:controller=>"sets"}
ultimately i want all the uris to be .../sets/...(controller name) instead of .../photosets/...(model name)
is there any way to do this and still be able to use the helpers?
--EDIT--
heres my rake routes output:
sets GET /sets(.:format) {:controller=>"sets", :action=>"index"}
POST /sets(.:format) {:controller=>"sets", :action=>"create"}
new_set GET /sets/new(.:format) {:controller=>"sets", :action=>"new"}
edit_set GET /sets/:id/edit(.:format) {:controller=>"sets", :action=>"edit"}
set GET /sets/:id(.:format) {:controller=>"sets", :action=>"show"}
PUT /sets/:id(.:format) {:controller=>"sets", :action=>"update"}
DELETE /sets/:id(.:format) {:controller=>"sets", :action=>"destroy"}
that all works just dandy, the problem is when i try to build a form off an instance of the model. I understand that rails has no way of knowing that im trying to tie the Photoset model directly with the Set controller, but I don't know how to specify that.
You have a Photoset model, Sets controller and urls need to be in form /sets/1/edit.
resources :sets, :as => "photosets"
Works with a simple form like this:
<%= form_for(#photoset) do |f| %>
<%= f.text_field :title %>
<%= f.submit "Save" %>
<% end %>
You should set
resources :photosets, :as => "sets"
which allow you to use photosets_path, photoset_path, new_photoset_path, etc... but shows the url as sets
