User model missing :created_at when using mongodb and haml

[pas256]

I'm not sure what the exact cause is, but with the following combination, either the user model is missing the created_at field, or the view has an extra column that uses the created_at field in user.

Option 1 - remove extra field by deleting these lines from app/views/users/index.html.haml.

        %th Registered
...
          %td= user.created_at.to_date

Option 2 - add the field to app/models/user.rb

class User
  include Mongoid::Document
  rolify
  field :provider, type: String
  field :uid, type: String
  field :name, type: String
  field :email, type: String
  field :created_at, type: DateTime  # Add this line
  attr_accessible :role_ids, :as => :admin
  attr_accessible :provider, :uid, :name, :email
  # run 'rake db:mongoid:create_indexes' to create indexes
  index({ email: 1 }, { unique: true, background: true })

  def self.create_with_omniauth(auth)
    create! do |user|
      user.provider = auth['provider']
      user.uid = auth['uid']
      if auth['info']
         user.name = auth['info']['name'] || ""
         user.email = auth['info']['email'] || ""
      end
      user.created_at = DateTime.now  # Add this line
    end
  end

end

Hope that helps.

The solution is to put include Mongoid::Timestamps in the User Model. I just figured this out and now created_at works great.

That include should be part of rails composer in my opinion.

Reference. http://mongoid.org/en/mongoid/docs/extras.html#timestamps

Here's my full User Model now

class User
  include Mongoid::Document
  include Mongoid::Timestamps
  rolify
  field :provider, type: String
  field :uid, type: String
  field :name, type: String
  field :email, type: String
  has_many :entries
  attr_accessible :role_ids, :as => :admin
  attr_accessible :provider, :uid, :name, :email
  # run 'rake db:mongoid:create_indexes' to create indexes
  index({ email: 1 }, { unique: true, background: true })

  def self.create_with_omniauth(auth)
    create! do |user|
      user.provider = auth['provider']
      user.uid = auth['uid']
      if auth['info']
         user.name = auth['info']['name'] || ""
         user.email = auth['info']['email'] || ""
      end
    end
  end

end

MongoDB and Mongoid are no longer supported by Rails Composer, as reported in this blog post: MongoDB Dropped From Rails Composer.

However, if you're interested in restoring Mongoid as an option in Rails Composer, you can join the MongoDB Rescue Operation. See the blog post for details.

Thank you for your support.
