Quite often your user can have multiple roles at the same time.
ActiveModel does not provide the ability to sanitize attributes using intersection of
attr_accessible for several role names at the same time.
This gem is all about to solve this problem.
Example of usage
Consider we have the following model code:
class Student < ActiveRecord::Base attr_accessible :phone_number attr_accessible :name, as: :admin attr_accessible :email, as: :user end
Now, while updating in controller we can write:
student = Student.find(params[:id]) if student.update_attributes(params[:student], :as => [:admin, :teacher])
Role names can be passed in
student.update_attributes(params[:student], :as => :admin)
all it's functionality is fully supported.
Several roles can be passed as an array symbols:
student.update_attributes(params[:student], :as => [:admin, :teacher])
But in most cases, role names can be obtained from user model. If your user
model provides method called
role_names, which returns as array of role
names, you can write code which is quite easy to understand.
class User < ActiveRecord::Base has_many :roles def role_names roles.map &:name end end
student.update_attributes(params[:student], :as => current_user)
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install mass_assignment_with_multiple_roles
