Also, the best approach was to use already existing standards.

So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.

## Design

Then I spent some time designing the developer "API" I wanted to have as a user (as a developer using FastAPI).

				if r, ok := rs.Relations[n]; !ok {
					t.Errorf("failed to find relation by name %s", n)
				} else {
					checkSchemaRelation(t, &schema.Schema{
						Relationships: schema.Relationships{
							Relations: map[string]*schema.Relationship{n: rel},
						},
					}, r)
				}
			}
			checkEmbeddedRelations(t, relations.EmbeddedRelations, rs.EmbeddedRelations)
		})
	}
}

	}
	return reflect.StructTag(fmt.Sprintf(`gorm:"%s;%s"`, value, t))
}

// GetRelationsValues get relations's values from a reflect value
func GetRelationsValues(ctx context.Context, reflectValue reflect.Value, rels []*Relationship) (reflectResults reflect.Value) {
	for _, rel := range rels {
		reflectResults = reflect.MakeSlice(reflect.SliceOf(reflect.PtrTo(rel.FieldSchema.ModelType)), 0, 1)

		appendToResults := func(value reflect.Value) {

		ModelType:        modelType,
		Table:            tableName,
		FieldsByName:     map[string]*Field{},
		FieldsByBindName: map[string]*Field{},
		FieldsByDBName:   map[string]*Field{},
		Relationships:    Relationships{Relations: map[string]*Relationship{}},
		cacheStore:       cacheStore,
		namer:            namer,
		initialized:      make(chan struct{}),
	}
	// When the schema initialization is completed, the channel will be closed

    // MAVENAPI FIXME: the DAG used is NOT only used to represent the dependency relation,
    // but also for <parent>, <build><plugin>, <reports>. We need multiple DAG's
    // since a DAG can only handle 1 type of relationship properly.
