Golang Gorm: Is it possible to delete a record via a many2many relationship?

Question

I have a many2many structure similar to GORM\'s example:

// User has and belongs to many languages, use `user_languages` as join table
type User struct {
    gor         


        

Answer 1

I was having the same problem, If you want to just remove one of the associations this worked for me

    c.DB.Model(&user).Association("Roles").Delete(&role)

Answer 2

I found a solution to this question, but not sure it's the best way to do this. I store the current languages, clear all the associations, then add back the languages, then save.

languages := user.Languages 
DB.Model(&user).Association("Languages").Clear()
user.Languages = languages

Answer 3

Also, you can do this by using "replace"

DB.Model(&user).Association("Languages").Replace(user.Languages)
