Weird generate path...

Hi, I have a simple form in my controller "before_home". In the form I want to create a user, si I use the users_path on my form. But look at the html generated... Why do I have an action before_home? I should be "users" in the action. Does someone knows where this could come from?

View: <% form_for users_path do |f| %>

    <p>       <%= f.label :email %>       <%= f.text_field :email %>       <%= f.label :ville %>       <%= text_field_with_auto_complete :user, :ville_name, { :size => 15 }, { :url => formatted_villes_path(:js), :method => :get, :param_name => 'search' } %>

      <%= f.submit "Suivant" %>     </p> <%end%>

Generated HTML: <form method="post" action="/before_home">       <input type="submit" value="Suivant" name="commit" id="/before_home_submit">

</form>

Hi,

form_for expects the first parameter to be a new user object and if that isn't supplied then the form action is set to the action that rendered the page; this is why you see action="/before_home". The reason user_path isn't working is because it doesn't reference a user object. If you wish to have the form submitted to /user then set up the user object and specify the url. See below...

To create a user I suggest you create a new user object and store it in an instance variable:

@user = User.new

Then in the form_for method you can use that value:

<% form_for :user, :url => { :controller => users_path } do |f| %>

Hope this helps

Thanks for your help Floyd, it works now. However, I have another issue. How do I display the errors regarding that my form is in a different controller.

    if @user.save       flash[:notice] = "Successfully created user."       redirect_to root_path     else       render :action => 'index', :controller => "before_home"     end

In response to your second question, you would not be able to redisplay the form with errors by using render because the action is in another controller. However you can render the template that created the form:

if @user.save   flash[:notice] = "Successfully created user."   redirect_to root_path else   render :template => "before_home/new" # I am assuming new was the action in before_home end

This will redisplay the form along with the errors.

However, you should consider your application design, it would be easier to control the creating and updating of records under the controller that is related to a specific model. Consider implementing a more RESTful application, contact for more info or if you have further problems.
