Question

This is what my Plan.rb looks like:

class Plan < ActiveRecord::Base

  has_many :users
  has_friendly_id :plan, :use_slug => true

end

User.rb

class User < ActiveRecord::Base

#There is other stuff in here, but I stripped it out for brevity purposes.

  has_and_belongs_to_many :projects
  has_many :stages
  has_many :uploads
  has_many :comments
  has_many :assignments
  has_many :roles, :through => :assignments
  belongs_to :plan


end

This is the error message I am getting:

Not sure what I am doing wrong here, but I can't create any new 'plans'.

Was it helpful?

Solution

It looks like your database doesn't have a plan column in your plans table. In addition to adding the has_friendly_id statement to your model, did you create and run a migration to add the plan field to your database?

OTHER TIPS

You can also get this error (undefined method `has_friendly_id') if you have upgraded friendly_id from Version 3 to 4.

Command 'has_friendly_id' has been replaced by 'friendly_id' - see how to upgrade here:

http://rubydoc.info/github/norman/friendly_id/master/file/WhatsNew.md

Note: You'll also need to create a migration to add a new slug column to your table.
