I'm using a gem called acts_as_commentable
I have added a custom column in the migration like: recipient_id
Then I generated a Comment model as per documentation:
rails g comment
Now, in my Comment.rb, I have following line:
validate :comment, :recipient_id, :presence => true
Note: comment column is already added by gem itself
Still, after following documentation, when I fire the following deliberately:
commentable = Post.create(:title => ......)
comment = commentable.comments.create
comment.comment = "Some comment"
comment.recipient_id = nil
comment.save!
The comment object seems like:
<Comment id: 1, comment: "Some comment", commentable_id: 1, commentable_type: "Post", recipient_id: nil, created_at: "2015-06-13 09:41:23", updated_at: "2015-06-13 09:41:23">
Why it's not validating presence of recipient_id?
Your are calling validate instead of validates. They both are different.
It should be:
validates :comment, :recipient_id, :presence => true
