My Code: models: has_many :skill_users, :dependent => :destroy has_many :users, :through => :skill_users has_many :skill_users, :dependent => :destroy has_many :skills, :through => :skill_users belongs_to :user belongs_to :skill skilluser table -id -skill_id -user_id -rating form: simple_form_for @user .... Skill.all.each do |skill| hidden_field_tag "user[skill_ids][]" check_box_tag "user[skill_ids][]", skill.id, @user.skills.include?(skill), { :id => "user_skills_ids_"+ skill.id.to_s} skill.name Rails 3.2 How do I manage to get the rating attribute attached to each checkbox and stored in the db? I can''t find a solution Googling. Would be great to get some help.. tried this: hidden_field_tag "skill_users[][skill_id]", skill.id text_field_tag "skill_users[][rating]" but no success.
