I have a problem with copying database records. I have a simple model User, that contains one-to-many relation with Language model and many-to-many relation with Skill model. I wanted to use amoeba gem to copy records with all associations. One-to-many copying works fine, but many-to-many doesn't copy at all.
Here's the code of User and Skill model:
user.rb
class User < ActiveRecord::Base
belongs_to :language
has_and_belongs_to_many :skills
validates_presence_of :email, :name
validates :email,
presence: { with: true, message: "cannot be empty" },
uniqueness: { with: true, message: "already exists in database" }
amoeba do
enable
end
end
skill.rb
class Skill < ActiveRecord::Base
has_and_belongs_to_many :users
end
I have also migration files that crates users, skills and skills_users tables:
class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :name, null: false
t.string :email, null: false
t.references :language
t.timestamps null: false
end
end
end
.
class CreateSkills < ActiveRecord::Migration
def change
create_table :skills do |t|
t.string :name
t.timestamps null: false
end
end
end
.
class AddUsersSkillsTable < ActiveRecord::Migration
def change
create_table 'skills_users', :id => false do |t|
t.column :user_id, :integer
t.column :skill_id, :integer
end
end
end
Controller action 'show' in users_controller looks like this:
def copy
@user_copy = @user.dup
if @user_copy.save(validate: false)
redirect_to action: "index"
end
end
I tried copying relations in user.rb like this, but it didnt work:
amoeba do
enable
clone [:skills]
end
What may cause the problem?
