Sample Data

[JaredBears]

This is in relation to Photogram Industrial Part 2, when it is time to generate sample data.

With the Follow Requests, I noticed when running the provided code that it had users following themselves, which seems like unintentional behavior and causes the task to take longer than it should.

I solved this by adding next if first_user == second_user to the sample data generation task:

  users.each do |first_user|
    users.each do |second_user|
      next if first_user == second_user

I also added the following custom validation to the follow_requests table:

  validate :sender_cant_follow_self

  def sender_cant_follow_self
    if sender_id == recipient_id
      errors.add(:sender_id, "can't follow self")
    end
  end

Well done! I'm going to leave off the custom validation (though I do like it) but I'll add the sample_data update to the lesson notes.
