Routes map and correct path

Rails
1

Hello everybody,

Here you can see my short code:

in routes.rb:

map.resources :users

in users_controller.rb

def new
@user = User.new
end

in views/users/new.html.erb:

<% form_for @user do |f| %>

And that work very well. I would like to update the current route like
this:

in routes.rb:

map.resources :apps do |app|
app.resources :users
end

in users_controller.rb

def new
@user = User.new
@user.app_id = the_current_app.id
end

But after refresh, I got this error:

NoMethodError in Users#new

Showing users/new.html.erb where line #1 raised:

undefined method `users_path’ for #ActionView::Base:0x20c4a34
Extracted source (around line #1):

1: <% form_for @user do |f| %>

Is there a clean way to solve this error? (I believe it’s possible to
add a :url parameter in the form_for tag but I don’t know if it’s the
best way.)

Thanks a lot

Try:

<% form_for @app, @user do |f| %>

Where your controller should look like

def new
@app = App.find(params[:app_id])
@user = User.new
@user.app_id = params[:app_id]
end

Sorry, it should be:

<% form_for [@app, @user] do |f| %>
