I am trying to add a new page to my RoR3 application that should display a delete confirmation of a user account. It should match the 'destroy' action in 'ROOT_RAILS/controllers/accounts_controller.rb'.
At this time my problem occurs on creating a "link_to" this page, but maybe I am wrong somewhere and my work is not completed yet.
So, what I made, is:
I created the 'ROOT_RAILS/views/accouns/delete.html.erb' file.
I updated the routes.rb like this:
resources :accounts do
collection do
get 'delete'
post 'delete'
end
end
I don't know the next steps, but now if I try to insert this code
<%= link_to 'Delete', delete_account_path(#current_account) %>
in my views, I will get this error:
undefined method `delete_account_path' for #<#<Class:0x00...>
What I have to do?
This "link_to" works, but, of course, doesn't make what I would like:
<%= link_to 'Delete', delete_users_accounts_path %>
Try the following:
config/routes.rb:
resources :accounts do
get :delete, :on => :member
end
In the view before the delete page:
<%= link_to 'Delete', delete_account_path(#current_account) %>
In the delete view(this will invoke the destroy method in your controller):
<%= link_to 'Delete', #current_account, :confirm => "Are you sure?", :method => :delete %>

I had my link for editing brands like this:
<%= link_to 'Edit', :action => 'edit', :id => brand %>
I found around here a way to make it look like a button, so I did this (not sure why the url helper method needs to be used, but with :action => 'edit' it didn't work, it kept thinking it was post action):
<%= button_to 'Edit', admin_brand_edit_path(brand), :method => "get" %>
However, the generated url is like this:
http://localhost:3000/admin/brand/edit.1
Where it should be
http://localhost:3000/admin/brand/edit/1
Result of rake routes for brand edit:
admin_brand_edit GET /admin/brand/edit(.:format) admin/brand#edit
admin_brand_update POST /admin/brand/update(.:format) admin/brand#update
routes.rb
get 'admin/brand/edit'
Below I have the link-helpers for the actions edit and destroy. The first link (and all the others) is working perfectly but the second creates a weird url that doesn't work.
<%= link_to "Edit", edit_event_path(organizer_vanity_url: event.organizer.vanity_url, id: event.id) %>
<%= link_to 'Remove', event_path(organizer_vanity_url: event.organizer.vanity_url, id: event.id), method: :delete, data: { confirm: 'Are you sure?' } %>
This is from the routes.rb:
scope "organizer" do
scope ":organizer_vanity_url" do
scope "manage" do
resources :events
end
end
end
What is the difference between the delete link-helper and the others (as that's the only one that doesn't work)?
link_to - is GET-request-like helper (by default)
DELETE method is POST-like method
so, you passing post method to get helper and receive "weird url"
to solve this you have two options:
use button_to instead of link_to helper (first one is for post form submitting, by default)
use js to correctly handle your link.
So if I want an edit link, I can do either of the following:
link_to 'Edit', edit_user_task_path(#user, #task)
link_to 'Edit', [:edit, #user, #task]
If I want to delete one however, I have to do:
link_to 'Delete', [#user, #task], method: :delete
Is it possible to make rails understand the following?
link_to 'Delete', [:delete, #user, #task]
It seems like it tries to go to the "delete_user_task_path", is there a shorter form for delete like there is the edit?
What you have to understand is that the array argument for the link_to method doesn't touch the request method (as far as I know).
As so, your suggestion would actually going to do a GET request to something like /user/:id/delete.
You could make this happen with something like
resources :user do
get :delete, on: :member
end
But that's not very RESTful, and I wouldn't recommend it.
We're adding a new method 'delete_stuff' to the WidgetsController of a scaffolded app.
in routes we added
match 'widget/delete_stuff/:id' => 'widgets#delete_stuff'
I CAN manually create html (GET) links like
My Custom Delete Stuff
But that's bad on so many levels (uses GET instead of DELETE, doesn't permit a CONFIRM dialog, isnt DRY, etc)
Problem is I can't figure out how to use the url helpers for a custom method... trying to do something like this:
<% link_to 'DeleteStuff', #widget, :confirm => 'Are you sure?', :method => :delete %>
But that just gets ignored when the html is rendered.
I'm clearly missing something fundamental on how to use link_to, any help will be appreciated!

Looks like you're missing an equals sign at the beginning. It should read:
<%= link_to 'DeleteStuff', #widget, :confirm => 'Are you sure?', :method => :delete %>
to solve your routing and make your additional action a delete method try this;
in routes.rb
resources :widgets do
member do
delete 'delete_stuff'
end
end
First run rake routes to know what URL helpers are available to you. You may see a line beginning with:
delete_stuff_widget
You can then append path or url to get the name you should use in your views and controllers. I suspect your new link_to will look like:
link_to "DeleteStuff", delete_stuff_widget_path(#widget), :confirm => "Sure?", :method => :delete
I have a Model with an attribute votes. I have a link in a view that needs to increment the value of votes - what is the best way to do this?
I am currently trying a link like:
<%= link_to 'Up', '#', :method => :voteup %>
and a voteup method in the model_controller but this isn't working.
I think the best way would be this:
In config/routes.rb:
resources :quotes do
member do
post :upvote
end
end
And your link:
<%= link_to 'Up', upvote_quote_path(#quote), :method => :post %>
Note that we use a POST request, which is more appropriate than a GET request when modifying a record.
:method is only supposed to be used to specify between POST, GET, DELETE, and PUT requests. Your second parameter of link_to should be the action you want to execute in your controller.
<%= link_to "Up", :action => :voteup %>
