I'm pretty new to RoR, please help me identify where I am wrong
I get the following error

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 keep getting this error when trying to view a page.

You want to do:
<%= link_to "Edit", edit_classified_path(:activation_code => classified)%>
or edit your routes.rb to:
match '/edit/:id', :controller => 'classifieds', :action => 'edit'
Your routes are very redundant and contradictory. First, try getting rid of the catch-all route:
match ':controller(/:action(/:id(.:format)))'
as it should not be used if you're using RESTful routes. If that doesn't help, let me know and I'll update my answer accordingly.
Further, all of your match routes are incorrect. They should follow the pattern:
match '/my_controller/:id' => 'my_controller#action'
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 %>

But if i submit form i have this error (for user or employee)

if you have an idea ?

The solution are in application_controller.rb.

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
