Disable timestamp fields for many_to_many relation table

[fnaysee]

I have two tables called tags and cards
There is also a table called card_tags for making relation between cards and their tags
I have disabled timestamp fields for the relation table because they are really unnecessary and i created a model CardTag with following content:

package models

type CardTag struct {
	CardId 	int64 `json:"card_id" db:"card_id"`
	TagId 	int64 `json:"tag_id" db:"tag_id"`
}

But in runtime sounds like the framework is not using above model and gives this error:

pq: column "created_at" of relation "card_tags" does not exist.

Is there a way to disable timestamps for this table ?

Thanks.
