Question

Im seriously stuck on an issue where I have a User and Profile model.
whatever I try it seems validations are not triggered for any of the Profile attributes

• The profile model belongs to User. User has_one Profile
• On registration form using fields_for to have some profile fields displayed ( gender, and city and country )
• Whatever I tried, I’m unable to let validation work for gender and city ( the fields_for profile fields)

My form:

- title t(:title, :scope => :register)
%h1= yield(:title)

  = simple_form_for(resource, :as => resource_name, :html => { :class => 'form-horizontal' } , :validate => true , :url => registration_path(resource_name)) do |f|

    = f.input :username,                  :label  => t(:username)
    = f.input :email,                     :label  => t(:email),
                                          :hint   => t(:hint_email_visible)
    = f.input :password,                  :label  => t(:password), :require => true
    = f.input :password_confirmation,     :label  => t(:password_confirm)


    - resource.build_profile
    = f.fields_for :profile do |f|

      #div

        = f.hidden_field :form, :value => "signup"

        .clear

        = f.input :gender,                :collection => [['Male', 'male'], ['Female', 'female']],
                                          :as => :radio

    = f.input :city,
              :readonly => "readonly",
              :label => t(:city)

    .ruler

    = f.input :country,
              :label => "Your country",
              :collection => [DataCountry.where(:code => 155).first],
              :value => @city,
              :id => "country",
              :name => "country"

    .clear


    = f.button :submit, t(:submit, :scope => :register) + " »"

My User model has this:

  accepts_nested_attributes_for :profile

My Profile model with validations is like:

  validates_presence_of :gender
  validates_presence_of :city
  validates_presence_of :country

My PARAMS:

-- !ruby/hash:ActiveSupport::HashWithIndifferentAccess
utf8: ✓
authenticity_token: <mytokenhere>
user: !ruby/hash:ActiveSupport::HashWithIndifferentAccess
  invite_code: ''
  username: username
  email: ''
  password: ''
  password_confirmation: ''
  profile_attributes: !ruby/hash:ActiveSupport::HashWithIndifferentAccess
    form: signup
    gender: male
    dob(3i): '9'
    dob(2i): '7'
    dob(1i): '1942'
    city: 'somevalue'
    country: 'somevalue'
commit: Register »
action: create
controller: registrations

Rails console does:

User.new


 => #<User id: nil, email: "", encrypted_password: "", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, password_salt: nil, confirmation_token: nil, confirmed_at: nil, confirmation_sent_at: nil, unconfirmed_email: nil, failed_attempts: 0, unlock_token: nil, locked_at: nil, authentication_token: nil, username: nil, is_blocked: nil, is_deleted: nil, role: nil, slug: nil, created_at: nil, updated_at: nil, last_seen: nil, credits: nil, invite_code: nil, is_moderated: nil, locale: nil, status: nil, login_token: nil> 

Profile.new

 => #<Profile id: nil, user_id: nil, gender: nil, country: nil, state: nil, city: nil, status: nil, counter_cache: nil>

UPDATE 19 Jul ’12

I added the

    - @user.errors.full_messages.each do |message|
  = message
  .clear

To the form to see what exactly is happening and this throws the following list of errors:

Email can't be blank
Email can't be blank
Password can't be blank
Password can't be blank
Profile city can't be blank
Profile gender can't be blank
Profile is invalid
Username can't be blank
Password confirmation can't be blank 

So it seems the validation is checked….
But no error styling is applied! Also the profile is invalid???? Im not sure but does that refer to the

Answer 1

Many hours spend trying to fix this now the solution is very simple based on suggestions in this topic I found out that instead of

WRONG:

- resource.build_profile

CORRECT:

- resource.build_profile unless resource.profile

what this does is not clean the profile but uses the old one if its available… so not cleaning out all the errors! hope this helps someone in the future!
