Formtastic issue

Rails
1

Hello,

I will try to explain it step by step :slight_smile:

I just created a new rails 3 app, then I created a new controller…

rails generate controller admin::users

I didn’t forget to add the resources in the routes.rb file like this.

namespace :admin do
resources :users
end

Now I try to use formtastic to create the form but I get erorr that my
users_path doesn’t exist?

undefined method `users_path’ for #<#Class:0x104169a40:0x104167df8>

…even though I have created resources for users.

Can someone explain to me what’s happening.

Thanks for any help :smiley:

Just in case anyone asked for the code.

It is simple:

Controller

class Admin::UsersController < ApplicationController
def new
@user = User.new
end
end

View

<% semantic_form_for @user do |form| %>
<%= form.inputs %>
<%= form.buttons %>
<% end %>

polymorphic_path([:admin,@user])

you can pass just the array [:admin,@user]

since you nested your route all you helper methods are now nested and
passing the usual wont work anymore

from now on is

show admin_user_path(@user) no more using just @user , you
can
also pass the array [:admin, @user]
index admin_users_path
new new_admin_user_path
edit edit_admin_user_path(@user)
destroy destroy_admin_user_path(@user)
create [:admin, User.new]
update [:admin, @user]

confirm all of the nested routes by doing rake routes , when i doubt use
polymorphic_path([:admin,@user]) this method will create the correct
path.

forgot to say that with polymorphic_path([:admin,@user]) you can pass
the
action as a parameter to the array , like this

polymorphic_path([:admin,:new,@user])

did you put the = after <% ?

Thanks for answer radhames,

I just tried it and it works.

But now it doesn’t print out the input fields, only the button on the
bottom?

Yes.

<% semantic_form_for polymorphic_path([:admin, @user]) do |form| %>
<%= form.inputs %>
<%= form.buttons %>
<% end %>

Another issue.

<form accept-charset="UTF-8" action="/admin/users/new"

It’s pointing on the wrong action? it should point to create POST,
right?

I just did [:admin, @user] and remove polymorphic and then it point
correct :smiley:

Thanx for help

try this

<% semantic_form_for polymorphic_path([:admin, @user]) do |form| %>
<% form.inputs do %>
<%= form.input :name %>
<%= form.input :last_name %>
<%end%>
<% form.buttons do %>
<%=f.commit_button “OMG”%
<%end%>
<% end %>

You nested the route and the controller when you did this
Admin::UsersController so action="/admin/users/new" is correct in fact
your
views should be in views/admin/user

class Admin::UsersController < ApplicationController
def new
@user = User.new
end
end

you are nesting

11

oh, good

12

if nothing show after this then check if you are creating and instance
of
user in the user controller

def new
@user = User.new
end

radhames, I’m having the exact same issue here. Here’s my code:

<%= semantic_form_for polymorphic_path([:admin, @user]) do |f| %>
<%= f.inputs do %>
<%= f.input :first_name %>
<%= f.input :last_name %>
<%= f.input :username %>
<%= f.input :email %>
<%= f.input :password, :as => :password %>
<%= f.input :role, :as => :select, :collection => User.roles.collect
{|x| x.to_s } %>
<% end %>
<%= f.buttons %>
<% end %>

No matter what I do – the action that sematic_form_for generates is:

/admin/users/new

instead of /admin/users

I even tried to add the absolute path

<%= semantic_form_for admin_users_path do |f| %>

and still the action for the form came out to be /admin/users/new

Let me know if there’s something I can do to get this working properly.

Thanks!

I switched to simple_form.

It’s simple and better :smiley:

Try

semantic_form_for [:admin, @user] do |f|
[… etc]

You shouldn’t need to supply a path at all in this case.

I thought that was the normal way to do it… :slight_smile: I never put a url
into
form_for unless it can’t correctly guess it from the object or object
array… Glad it solved the problem.

Hehe – that’s awesome … the [ :admin, @user ] trick worked in
formtastic and in simple_form :slight_smile: …

Thanks!

semantic_form_for @user, :url => polymorphic_path( [:admin, @user] )
do |f|

should also works fine.
