Question

I would like to use the group_by method, but instead of using a column in the database:

@posts.group_by(&:date)

I want to have something like:

@posts.group_by(&:author)

Where post belongs_to author.

I’m just not sure of the syntax?

Answer 1

You can write in your model:

def author_name
  self.author.name
end

and then

@posts.group_by(&:author_name)
