db.Find(&Srt) raise error:
field XXX_NoUnkeyedLiteral: define a valid foreign key for relations or implement the Valuer/Scanner interface
HOW：add filter: field.Tag.Get("json") != "-"
WHY：unsupported parsing type: struct{} set guessLevel to guessEmbeddedHas
have been commented:schema/relationship.go:381
as follows：
reguessOrErr := func() {
switch cgl {
case guessGuess:
schema.guessRelation(relation, field, guessBelongs)
case guessBelongs:
schema.guessRelation(relation, field, guessEmbeddedBelongs)
case guessEmbeddedBelongs:
schema.guessRelation(relation, field, guessHas)
case guessHas:
schema.guessRelation(relation, field, guessEmbeddedHas)
// case guessEmbeddedHas:
default:
schema.err = fmt.Errorf("invalid field found for struct %v's field %s: define a valid foreign key for relations or implement the Valuer/Scanner interface", schema, field.Name)
}
}
