Form submission in rails 3

I decided to start a little project in rails 3 and I am a little bit stuck on a form... Where 开发者_开发百科can I specified the f.submit action should go to a special controller / action ?

The code in the form is:

<%= form_for @user, :url => { :action => "login" } do |f| %>
<div class="field">
<%= f.text_field :email %><br />
<%= f.text_field :password %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>

User is defined as @user = User.new in "index" method of "home_controller".

but I have the error:

No route matches {:controller=>"home", :action=>"login"}

as soon as I run http://0.0.0.0:3000

I am very sorry for this newbee question but I cannot find the routing details (I worked a little bit with rails a couple of years ago but...)

Thanks, Luc

You don't need to specify any action for f.sumbit. First of all, you need to make sure you put

 resources :users 

(for example)

in your routes.rb

then if you want to create a user

put

  def new

     @user = User.new

 end

in your users_controller so you have a page to create new user or you can put @user=User.new anywhere you like, remember to set the route correctly

then

      def create


    @user = User.new(params[:id])

    if @user.save
        sign_in @user

        redirect_to @user
    else

        render 'new'
    end

 end

is the part that does real work after you hit on submit

the actual part that connect your form with everything else is this line

<% form_for @user do |f| %>

you can change user to other object, and you can also edit form using update action in a controller.

Hope you got the idea

Whenever you use REST objects, the mere:

form_for @article

is enough for the form to find the proper path.

Otherwise, you can use helpers this way:

form_tag(:controller => "people", :action => "search", :method => "get", :class => "nifty_form")
