I'm trying to add a link so the user can destroy his/her own account. I'm using the built-in registration class.
In my view I have <%= link_to 'Destroy', current_user, :confirm => 'Are you sure you want to destroy your account?', :method => :delete %> pointing to localhost:3000/users/4 by example
First of all, is that the correct link to use?
Secondly, how to redirect to root path because presently it looks like it tries to redirect to user with id 4 (and it fails because it is protected).
Rake routes gives DELETE /users(.:format) {:action=>"destroy", :controller=>"devise/registrations"}
Thanks in advance.
Try
<%= link_to 'Destroy', user_registration_path, :confirm => 'Are you sure you want to destroy your account?', :method => :delete %>
It's because of devise treat registration as Singular Resource.
Besides, run rake routes and you can see details about registration routing:
user_registration POST /users(.:format) {:action=>"create", :controller=>"devise/registrations"}
new_user_registration GET /users/sign_up(.:format) {:action=>"new", :controller=>"devise/registrations"}
edit_user_registration GET /users/edit(.:format) {:action=>"edit", :controller=>"devise/registrations"}
user_registration PUT /users(.:format) {:action=>"update", :controller=>"devise/registrations"}
user_registration DELETE /users(.:format) {:action=>"destroy", :controller=>"devise/registrations"}
It means:
user_registration_path is a helper method that returns /users(.format)
Perform DELETE request on /users(.format) will delete the registration

please help me figure out how to fix the problem
many thanks.
UPD
here is solution, it works
I made all changes suggested by #Abibullah and two changes in controllers
view:
<li><%= link_to 'My groups', user_groups_path(current_user) %></li>
<li><%= link_to 'New group', new_user_group_path(current_user) %></li>
routes.rb
resources :users do |user|
resources :groups do |group|
resources :people
end
end
devise_for :users
GroupsController.rb:
def index
#user = current_user
#user.groups = Group.all
was:
def index
#user = current_user
#groups = Group.all
end
UsersController.rb
class Devise::UsersController < DeviseController
def show
end
end
To Create a nested Group Inside User, U need to pass the user_id inside which U are Creating the Group.
For Ex: If I have user1
Then I will use the routes as this:
link_to 'My groups', user_groups_path(user1)
OR
link_to 'My groups', user_groups_path(user1.id)
AND
link_to 'My Group', new_user_group_path(user1)
OR
link_to 'My Group', new_user_group_path(user1.id)
This is to tell that, To which User you are creating the Group.
If U want to access any specific Group, say for ex: grp1
then My url will be
link_to 'My Group', user_group_path(user1, grp1)
THis is a good refrence for routing.
http://guides.rubyonrails.org/routing.html
I think it's obvious. You've got a typo in your
<li><%= link_to 'My groups', user_groups_path %></li>
link. The path should be user_group_path (without the 's') as shown in your rake routes output, instead of the one you've written in your link.
I'm trying to update a single databasefield of my current_user (devise).
I want to do this just with the link_to helper:
<%= link_to "Grid", edit_user_registration_path(current_user, :project_view => "grid"), :method => :put %>
But I can't get it to work since the result it allways an error:
Routing Error
No route matches [PUT] "/users/edit.1"
My Routes for Devise:
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy
user_password POST /users/password(.:format) devise/passwords#create
new_user_password GET /users/password/new(.:format) devise/passwords#new
edit_user_password GET /users/password/edit(.:format) devise/passwords#edit
PUT /users/password(.:format) devise/passwords#update
cancel_user_registration GET /users/cancel(.:format) devise/registrations#cancel
user_registration POST /users(.:format) devise/registrations#create
new_user_registration GET /users/sign_up(.:format) devise/registrations#new
edit_user_registration GET /users/edit(.:format) devise/registrations#edit
PUT /users(.:format) devise/registrations#update
DELETE /users(.:format) devise/registrations#destroy
What's wrong with the routing? I'm using devise without any custom modifications.
Thanks!
Wrong path helper:
$ rake routes
new_user_registration GET ... registrations#new
cancel_user_registration GET ... registrations#cancel
user_registration POST ... registrations#create
edit_user_registration GET ... registrations#edit
users PUT ... registrations#update # You want this one
DELETE ... registrations#destroy
Result:
<%= link_to "Grid", users_path(:user => {:project_view => 'grid'}), :method => :put, :confirm => "Are you sure?" %>
Update for your specific routes:
<%= link_to "Grid", registration_path(resource_name, :user => {:project_view => 'grid'}), :method => :put, :confirm => "Are you sure?" %>
I'm really starting to cry here ;) Trying to make a link in a Models index view.
I have 2 simple Models: Users and Posts. There both generated with scaffolding and have working joins. A user has_many :posts and a post belongs_to :user.
What I'm trying to do in the views/post/index.html.er file is a list of the Post title and the user who it belongs to. It works well (also learning html5):
<% #posts.each do |post| %>
<p><%= link_to post.user.name, users_path %>: <b><%= post.title %></b></p>
<% end %>
Well, it works but the "users_path" is not what I want. I want to link to the specific User which the post belongs_to. I'm sorry to say that I don't get much help from http://guides.rubyonrails.org/routing.html.
How should I do this? Do I have to specify a #user in the posts_controller index-action? I reallt appreciate long and detaild answears here.
Tnk soooo much for patience with a beginner ;)
you probably have this in your routes -
resources :posts do
resources :users
end
rake routes would generate the following mapping -
post_users GET /posts/:post_id/users(.:format) {:action=>"index", :controller=>"users"}
POST /posts/:post_id/users(.:format) {:action=>"create", :controller=>"users"}
new_post_user GET /posts/:post_id/users/new(.:format) {:action=>"new", :controller=>"users"}
edit_post_user GET /posts/:post_id/users/:id/edit(.:format) {:action=>"edit", :controller=>"users"}
post_user GET /posts/:post_id/users/:id(.:format) {:action=>"show", :controller=>"users"}
PUT /posts/:post_id/users/:id(.:format) {:action=>"update", :controller=>"users"}
DELETE /posts/:post_id/users/:id(.:format) {:action=>"destroy", :controller=>"users"}
posts GET /posts(.:format) {:action=>"index", :controller=>"posts"}
POST /posts(.:format) {:action=>"create", :controller=>"posts"}
new_post GET /posts/new(.:format) {:action=>"new", :controller=>"posts"}
edit_post GET /posts/:id/edit(.:format) {:action=>"edit", :controller=>"posts"}
post GET /posts/:id(.:format) {:action=>"show", :controller=>"posts"}
PUT /posts/:id(.:format) {:action=>"update", :controller=>"posts"}
DELETE /posts/:id(.:format) {:action=>"destroy", :controller=>"posts"}
The above explains the url you can use and what objects need to be passed.
For linking the user of the post -
<%= link_to "Post User details", post_user_path(post, post.user) %>
OR
<%= link_to "Post User details", url_for([post, post.user]) %>
Yet when run rake:routes it appears to be there:
users GET /users(.:format) {:action=>"index", :controller=>"users"}
POST /users(.:format) {:action=>"create", :controller=>"users"}
new_user GET /users/new(.:format) {:action=>"new", :controller=>"users"}
edit_user GET /users/:id/edit(.:format) {:action=>"edit", :controller=>"users"}
user GET /users/:id(.:format) {:action=>"show", :controller=>"users"}
PUT /users/:id(.:format) {:action=>"update", :controller=>"users"}
DELETE /users/:id(.:format) {:action=>"destroy", :controller=>"users"}
sessions POST /sessions(.:format) {:action=>"create", :controller=>"sessions"}
new_session GET /sessions/new(.:format) {:action=>"new", :controller=>"sessions"}
session DELETE /sessions/:id(.:format) {:action=>"destroy", :controller=>"sessions"}
signup /signup(.:format) {:controller=>"users", :action=>"new"}
contact /contact(.:format) {:controller=>"pages", :action=>"contact"}
about /about(.:format) {:controller=>"pages", :action=>"about"}
help /help(.:format) {:controller=>"pages", :action=>"help"}
root /(.:format) {:controller=>"pages", :action=>"home"}
Here are the routes from routes.rb:
resources :users
resources :sessions, :only => [:new, :create, :destroy]
match '/signup', to: 'users#new'
match '/contact', to: 'pages#contact'
match '/about', to: 'pages#about'
match '/help', to: 'pages#help'
It's possible that you are not passing the :id param in your route, which is why the route is not matched, since :id is required:
session DELETE /sessions/:id(.:format) {:action=>"destroy", :controller=>"sessions"}
Note: The parentheses around the :format param mean that it is optional.
I got the same error as well.But the reason is the little mistake that in the view page I write
<%= form_for(:session,url:session_path) do |f| %>
which I less the last 's' of 'sessions'.
This looks like an error I was running into when running through http://ruby.railstutorial.org/, and it turned out that I had left a few things out of routes.rb. The addition of the resource route is accompanied by the following two additional routes:
match '/signin', :to => 'sessions#new'
match '/signout', :to => 'sessions#destroy'
It's hard to see because the first route in that group is already there, so I had just glossed over the group (several times) as already being there.
resources controller adds map to method
{:action=>"method", :controller=>"controller"}
when in your case the rails seemed to ask for explicitly the map as
{:controller=>“controller”, :action=>“method”}
The :controller is before :action
This also answered Noach's question why match '/signout', :to => 'sessions#destroy' has to exist, if you rake:routes you will see it added
{:controller=>“sessions”, :action=>“destroy”} while there is already a
{:action=>“destroy”, :controller=>“sessions”} added by resources sessions
I am using resources :users in routes.rb. This provides the following paths as rake routes unveils.
users GET /users(.:format) {:action=>"index", :controller=>"users"}
POST /users(.:format) {:action=>"create", :controller=>"users"}
new_user GET /users/new(.:format) {:action=>"new", :controller=>"users"}
edit_user GET /users/:id/edit(.:format) {:action=>"edit", :controller=>"users"}
user GET /users/:id(.:format) {:action=>"show", :controller=>"users"}
PUT /users/:id(.:format) {:action=>"update", :controller=>"users"}
DELETE /users/:id(.:format) {:action=>"destroy", :controller=>"users"}
Further, I comment out the legacy wild controller route.
#match ':controller(/:action(/:id(.:format)))'
To add a delete link on my users page I add the following.
<%= link_to "Delete user", user, :method => :delete, :confirm => "Are you sure?" %>
This generated the following html code.
Delete user
I click the link and it takes me to the show page?! What's wrong?
You need to include the default Javascript files for that to work properly:
<%= javascript_include_tag :defaults %>
