Question

Haveing a little trouble getting a grasp on mongoid and active record validations.

My Model:

    class Project
        include Mongoid::Document

        field :name
        field :public, :type=>Boolean

        #validation
        validates_acceptance_of :public
    end

And In my controller I call:

    Project.create!(:name => 'Test Project', :public => false)

But I keep getting an error that says: Public must be accepted.

Any thoughts on why I am getting this error although I am creating an entry with a boolean in the public field?

Answer 1

From the fine manual:

Encapsulates the pattern of wanting to validate the acceptance of a terms of service check box (or similar agreement).

The idea is that they have to check the :public checkbox and that should result in a true value; but false being a non-true value will fail the validation and the validator will tell you that “Public must be accepted”.

Maybe you’re looking for:

Project.create!(:name => 'Test Project', :public => true)

The documentation also says:

This check is performed only if terms_of_service is not nil …

And the terms_of_service refers to their example. So you could also do this:

Project.create!(:name => 'Test Project', :public => nil)
Project.create!(:name => 'Test Project')

if you wanted to get an entry in MongoDB that looked like someone slipped past your validations.
