Hi, thank you for that.
I have made that change. From
belongs_to :tag
belongs_to :posts
to
belongs_to :tag
belongs_to :post
However. I am still getting the same error.
Looking at many similar open stackoverflow answers and questions I honestly
thought the pluralization was going to fit it. But unfortunately it still
hasn't.
