before_create doesn't work in rails
ruby-on-rails
Solution
This will almost certainly be a validation issue:
#app/models/profile.rb
validates_length_of :phone_number, :minimum => 11, :maximum => 11
validates_length_of :nic_code, :minimum => 10, :maximum => 10, :allow_blank => true
When you `build` an ActiveRecord object, the models will not be populated with data. This means your validations are going to have no data to validate, which I believe will throw the error
You need to test by removing the `length` & `presence` validations in your `Profile` model:
#app/models/profile.rb
class Profile < ActiveRecord::Base
belongs_to :user
# -> test without validations FOR NOW
end
Problem
In a rails project, I have 3 controllers and models, user, responsibility and profile. I have below code: `user.rb` ``` class User < ActiveRecord::Base # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable has_one :responsibility has_one :profile before_create :build_responsibility before_create :build_profile end ``` `responsibility.rb` ``` class Responsibility < ActiveRecord::Base belongs_to :user end ``` `profile.rb` ``` class Profile < ActiveRecord::Base belongs_to :user validates :user_id, uniqueness: true validates_numericality_of :nic_code, :allow_blank => true validates_numericality_of :phone_number validates_length_of :phone_number, :minimum => 11, :maximum => 11 validates_length_of :nic_code, :minimum => 10, :maximum => 10, :allow_blank => true has_attached_file :photo, :styles => { :medium => "300x300>", :thumb => "35x35>" }, :default_url => "profile-missing.jpg" validates_attachment_content_type :photo, :content_type => [ 'image/gif', 'image/png', 'image/x-png', 'image/jpeg', 'image/pjpeg', 'image/jpg' ] end ``` Now, when I created a new user, `before_create` works for `responsibility` and creates it, but for `profile` it's not working and doesn't create a new profile. Is there a difference between `profile` and `responsibility`? Why `before_create` works for `responsibility`, but doesn't work for `profile`?
