Rails: form for different controller

Question

I'm developing a rails app with a landingpage. On the landingpage, the user can sign up for the app. For login, there is an extra view with an extra controller.

It looks like this:

views/landinpage/index.html --> sign up form
views/login/index.html --> login form

but I only want to have one controller

controllers/login_controller --> create new user from sign up form & check login data

so I have to get a connection between the landingpage view and the login_controller.

This is my attempt:

<%= form_for @login, :url => { :controller => "login_controller", :action => "create" }, :html => {:method => :post} do |f| %>

but it throws a route error:

No route matches {:controller=>"login_controller", :action=>"create"}

I already defined login resources in routes.rb, but it seems that the problem is elsewhere?

resources :logins

any ideas?

try this

class LoginsController < ApplicationController
   def new
     ...
   end

   def create
     ...
   end
  ...
 end

in your route.rb file write

  match '/login/create' => 'logins#create', :as => :create_login
  or
  resources :logins

in your console - write - rake routes and check your routes

then

<%= form_for @login, :url => create_login_path(@login) do |f| %>

Thanks a lot! Works perfectly. But i have a question left: I have to create a /login/create view. Can i define a redirect to the landingpage after the user submitted the form by changing the routes?

Dipak Panchal Over a year ago

after submit form you want to display a create action view page?

Slevin Over a year ago

Nope. The user should submit the form on the landingpage. After submitting, the user should not redirect to the "login/create" view but to the landingpage.

ok. in your create action you can define redirect_to landingpage_path. and define routes for landingpage like -- match '/landingpage' => 'controller-name#action name', :as => :landingpage

I think your code should look like this:

<%= form_for @login, :url => { :controller => "login", :action => "create" }, :html => {:method => :post} do |f| %>

can't test this right now, but I believe the _controller part is not required.

Update:

Another thing that I'm using a lot and that works:

<%= form_for @login, :url => create_login_path(@login), :html => {:method => :post} do |f| %>

You may have to fix the create_login_path part to match your application's routes but that's how I usually define these views.

unfortunately, it throws: No route matches {:controller=>"login", :action=>"create"}

Try this

class LoginsController < ApplicationController
   def new
     ...
   end

   def create
     ...
   end
  ...
 end

in your routes.rb file

resources :logins do
    collection do
      post :create
    end
  end

and in your views

<%= form_for @login, :url => create_login_path(@login) do |f| %>>

you can see the html form action part, you can see!

your config/routes has

resources :posts

namespace :admin do
  resources :posts
end
