wrong foreignKey setup for multiple ebedded belongs-to relations

[cstaud]

Explain your user case and expected results

When using multiple embedded belongs-to relations only 1 database foreignKey is created. Expected: a foreignKey for each relation is created.

type Country struct {
	Name string `gorm:"primaryKey"`
}

type Address struct {
	CountryName string
	Country     Country
}

type Org struct {
	ID       int
	Address1 Address `gorm:"embedded;embeddedPrefix:address1_"`
	Address2 Address `gorm:"embedded;embeddedPrefix:address2_"`
}

In the above example there should be a foreignKey for address1 -> countries and a foreignKey address2 -> countries. gorm only creates one foreignKey fk_orgs_country => address2_country_name->countries

Hint:

• the generated naming for the foreignKey should respect the fieldName with its path / parent struct, as both relations result in the same foreignKey name.
• the relations are correctly detected as embedded and belongs-to, but result in only one entry in the relations map, this is due to the fact that only fieldName is used within this map
• possible solution: consider using BindNames of the field for name generation
