actually i use the following code in my _user.html.erb:
<%= link_to "Delete User", user, method: :delete, data: { confirm: "Are you sure?" } %>
For every user i get a link to delete him.
In my controller the delete-method calls the destroy-method:
def destroy
User.find(params[:id]).destroy
flash[:success] = "User deleted."
redirect_to users_url
end
This all works fine.
What i want now is another link where a call a custom method.
How can i call a custom method?
What i already tried was to add a method with the name test and then i called method: :test but this doesn't work:
No route matches [POST] "/users/2"
Thanks for any idea
Question heading is wrong, pagination means something else.
First configure your routes like
resources :controller_name do
member do
delete 'test'
end
end
Your route will be set ..
test_controller_name DELETE /controller_name/:id/test(.:format) controller_name#test
Call the action from link_to and pass the object id .
<%= link_to 'Destroy', test_controller_path(:id => #object.id), method: :delete, data: { confirm: 'Are you sure?' } %>

I am working on the destroy functionality for a small rails app. Currently, when I click delete I get the following error:
No route matches [POST] "/note/1"
Here is the relevant controller method:
def destroy
if Note.find(params[:id]).destroy
redirect_to note_index_path, notice: 'Note deleted!'
else
redirect_to note_path, notice: 'Note failed to updated'
end
end
Here is a link example:
<p><%= link_to 'Delete Note', { action: :destroy, id: #note.id }, method: :destroy, data: { confirm: 'Are you sure?' } %></p>
Here are the routes:
Prefix Verb URI Pattern Controller#Action
note_index GET /note(.:format) note#index
POST /note(.:format) note#create
new_note GET /note/new(.:format) note#new
edit_note GET /note/:id/edit(.:format) note#edit
note GET /note/:id(.:format) note#show
PATCH /note/:id(.:format) note#update
PUT /note/:id(.:format) note#update
DELETE /note/:id(.:format) note#destroy
root GET / note#index
You don't need to specify the action in the link_to helper when you make a DESTROY request, try just passing the resource, and specifying the method as delete:
<p><%= link_to 'Delete Note', #note, method: :delete, data: { confirm: 'Are you sure?' } %></p>
The #note object will give you the id, also without having to specify it.
If you make your route wait for a param id like /note/:id, then Rails will take the id value for the object passed as the second parameter in your link_to in this case.
I am trying to delete a particular "work" from an array of "works" which is embedded in user.
In my work.html.erb file in views:-
<% #works.each do |f| %>
<%= link_to 'Destroy', profiles_destroy_path(f), data: {:confirm => 'Are you sure?'}, :method => :delete %>
<% end %>
And in my controller:-
def destroy
#work = current_user.works.find(params[:id])
#work.destroy
respond_to do |format|
format.html { redirect_to root_url }
end
end
I am getting following error:-
Mongoid::Errors::InvalidFind at /profiles/destroy.56fa4d2f498b5908a002e2e8
P.S. - I am new to rails.
Please check params[:id] is not nil. There's no :id at session start and you get the Mongoid::Errors::InvalidFind exception above.
delete action doesn't have path by default..
<%= link_to 'Destroy', profiles_path(f), data: {confirm: 'Are you sure?'}, method: :delete %>
That will call the destroy action from your controller.
And make sure params[:id] is not nil.
PS: use rails 4 annotation (avoid using rockets (=>))
There may be an error in Juan's answer.
I believe you want:
<%= link_to 'Destroy', profile_path(f), method: :delete, data: {confirm: 'Are you sure?'} %>
Note: the singular "profile_path" instead of "profiles_path"
This is because the destroy action uses the same path as the show action, but uses a DELETE method instead of a GET. (Which you can observe by running "rake routes" in your terminal and comparing the two routes.)
I have this code in a helper file:
def admin_post_edit_destroy(post)
if current_user.admin?
link_to 'Edit', edit_post_path(post)
link_to "delete", post, method: :delete, data: { confirm: "You sure" }
end
end
I got it to return the delete.
I was just wondering what do I need add to make it display the edit link in addition to the delete link? Do I type && or + or something else?
The problem you are having is that a ruby method automatically returns only the value of the last item calculated, so you are only getting the delete link back. Try adding the two links together like this:
def admin_post_edit_destroy(post)
if current_user.admin?
link_to('Edit', edit_post_path(post)) + link_to('Delete', post, method: :delete, data: { confirm: "You sure" })
end
end
You could also return two values from the helper method:
def admin_post_edit_destroy(post)
if current_user.admin?
return link_to('Edit', edit_post_path(post)), link_to('Delete', post, method: :delete, data: { confirm: "You sure" })
end
end
Then you can call the method like this to get the two return values in the two variables (edit_link and delete_link):
edit_link, delete_link = admin_post_edit_destroy(#post)
I am beginner to ROR and I am following this tutorial http://guides.rubyonrails.org/getting_started.html.
So according to this tutorial I want to delete one post. But its not working it showing this error The action 'destroy' could not be found for PostsController
My post controller delete method looks like
def destroy
#post = Post.find(params[:id])
logger.debug "***********************: #{#post.id}"
#post.destroy
redirect_to posts_path
end
In routes I mentioned resource resources :posts but still it is giving error for destroy action. Am I doing something wrong. Need Help.
Did you mention the method as delete in your views?
If you are using Rails 4, you should do:
<%=link_to 'Destroy', post_path(post), method: :delete, data: { confirm: 'Are you sure?' } %>
In Rails 3:
<%=link_to 'Destroy', post_path(post), method: :delete, confirm: 'Are you sure?' %>
I have a List object, with nested Tasks. I have created a page that displays individual tasks, and also a page that allows a user to edit individual tasks. I now want to add the ability to delete a task from a list on the tasks edit page. Using the following code
<%= link_to 'Delete this task',#task, confirm: 'Are you sure?', method: :delete %>
yields
undefined task_path method
This code is on the show.html.erb page, where I call #task to display all of the data stored within the task, so I believe that this issue may be a routing error of some kind, however I cannot seem to figure it out.
The related controller method is
def destroy
#task = Task.find(params[:id])
#task.destroy
respond_to do |format|
format.html { redirect_to list_tasks_path(#task) }
format.json { head :ok }
end
end
I thought that with the delete method the #task I supplied would just be sent to the destroy method via params, but this error seems to be showing that this isn't exactly how it works. So how can I properly destroy a nested resource in Rails?
edit:
Here is the route file with nested resources:
MyApp::Application.routes.draw do
resources :lists do
resources :tasks
end
get "home/index"
root :to => 'home#index'
end
Thank you for your help!
You should have #list setup, or use #task.list (assuming you have a belong to relationship), and you could do the following:
<%= link_to "Delete this task", list_task_path(#task.list, #task), confirm: "Are you sure?", method: :delete %>
Cheers!
Try this:
<%= link_to 'Delete this task', list_task_path(#list, #task), confirm: 'Are you sure?', method: :delete %>
Or if you want it more compact (like you've written it):
<%= link_to 'Delete this task', [#list, #task], confirm: 'Are you sure?', method: :delete %>
Either way, since it's a nested resource, you must pass in both the #list and #task objects.
