Rails - Will_Paginate Says "Variable Appears to Be Empty. Did You Forget to Pass the Collection Object for Will_Paginate"

Rails - will_paginate says variable appears to be empty. Did you forget to pass the collection object for will_paginate?

You can do something like this in your controller:

@car_paginator = Car.paginate(page: params[:page], per_page: 5).order(created_at: :desc)
@cars = @car_paginator.group_by { |r| r.created_at.to_date }

Then change the line with the pagination in your view:

= will_paginate @car_paginator

The problem is: When you use the paginate method the results is not a normal array or database relation but an object that has some extra information like @size. If you run group_by on that you remove that extra attributes and return a plain hash.

Did you forget to pass the collection object for will_paginate? Rails

<%= will_paginate @conversations %>
Check this you need to pass the variable, you want to paginate.

EDIT

Update the User model as below:

class User < ActiveRecord::Base

  has_many :sender_questions, :class_name => 'Question', :foreign_key => 'sender_id' 
  has_many :recipient_questions, :class_name => 'Question', :foreign_key => 'recipient_id'

end

def show
  @user = User.find(params[:id]) 
  @question = @user. recipient_questions.paginate(page: params[:page])
end
