Unique constraint error on a schema less many to many association table
I have a posts table which has many tags. The 2 are linked by a many to many association through an post_tags table. There is no schema for post_tags table. So, I use put_assoc/4 to insert data to post_tags table. Now, how can I add a unique constraint error to the Changeset when creating/editing a post?
