Passing an array into hidden_field ROR
- by JZ
I'm trying to pass an array into a hidden_field.
The following User has 3 roles [2,4,5]
>> u = User.find_by_login("lesa")
=> #<User id: 5, login: "lesa", email: "[email protected]", crypted_password: "0f2776e68f1054a2678ad69a3b28e35ad9f42078", salt: "f02ef9e00d16f1b9f82dfcc488fdf96bf5aab4a8", created_at: "2009-12-29 15:15:51", updated_at: "2010-01-06 06:27:16", remember_token: nil, remember_token_expires_at: nil>
>> u.roles.map(&:id)
=> [2, 4, 5]
Users/edit.html.erb
<% form_for @user do |f| -%>
<%= f.hidden_field :role_ids, :value => @user.roles.map(&:id) %>
When I submit my edit form, I receive an error: ActiveRecord::RecordNotFound in UsersController#update "Couldn't find Role with ID=245"
How can I pass an array into the hidden_field?
