class Tag < ApplicationRecord

  has_many :taggings
  has_many :posts, through: :taggings

  def self.counts
    self.select("name, count(taggings.tag_id) as count").joins(:taggings).group("name, taggings.tag_id")

class Tagging < ApplicationRecord
  belongs_to :post
  belongs_to :tag
end

Answer 1

Tag_id not found in taggings table?

Answer 2

when generating a model

$ rails g model tagging post:belongs_to tag: belongs_to

accidentally put a space after tag:
