Generic Collection
mongox
provides a generic Collection
object, which supports chainable calls to operate on MongoDB
collections, making data operations more convenient.
Create a Collection
go
type User struct {
mongox.Model `bson:"inline"`
Name string `bson:"name"`
Age int `bson:"age"`
}
// Sample code, not the best way to create it
func newCollection() *mongo.Collection {
client, err := mongo.Connect(context.Background(), options.Client().ApplyURI("mongodb://localhost:27017").SetAuth(options.Credential{
Username: "test",
Password: "test",
AuthSource: "db-test",
}))
if err != nil {
panic(err)
}
err = client.Ping(context.Background(), readpref.Primary())
if err != nil {
panic(err)
}
collection := client.Database("db-test").Collection("test_post")
return collection
}
// You need to create a *mongo.Collection object in advance
mongoColl := newCollection()
// Create a collection using the User struct as a generic parameter
userColl := mongox.NewCollection[User](mongoColl)
With the mongox.NewCollection
function, we can specify generic parameters and create a generic Collection
object. This way we can use the userColl
object to manipulate the document of type User
.
