Question

I want to do something like this:

Given:

@user1
@user2

Where the Post model has (id, user_id)

@posts = @user1.posts

I want to take all of the posts of user1, and set the user_id to @user2

Is there an easy one liner way to do this? Or do I have to loop through all the @posts and update attributes and save the record?

Thanks

Answer 1

You can use the class method update_all on your Post class to accomplish this. The first string passed is essentially the SET clause of an SQL update statement, the second string is the WHERE clause.

Post.update_all("user_id = #{@user2.id}", "user_id = #{@user1.id}")
