type Client ¶
type Client struct { // Schema is the client for creating, migrating and dropping schema. Schema *migrate.Schema // Group is the client for interacting with the Group builders. Group *GroupClient // User is the client for interacting with the User builders. User *UserClient // contains filtered or unexported fields }
Client is the client that holds all ent builders.
func FromContext ¶
FromContext returns a Client stored inside a context, or nil if there isn't one.
func Open ¶
Open opens a database/sql.DB specified by the driver name and the data source name, and returns a new client attached to it. Optional parameters can be added for configuring the client.
func (*Client) Debug ¶
Debug returns a new debug-client. It's used to get verbose logging on specific operations.
client.Debug(). Group. Query(). Count(ctx)
type CommitFunc ¶
The CommitFunc type is an adapter to allow the use of ordinary function as a Committer. If f is a function with the appropriate signature, CommitFunc(f) is a Committer that calls f.
type CommitHook ¶
CommitHook defines the "commit middleware". A function that gets a Committer and returns a Committer. For example:
hook := func(next ent.Committer) ent.Committer { return ent.CommitFunc(func(context.Context, tx *ent.Tx) error { // Do some stuff before. if err := next.Commit(ctx, tx); err != nil { return err } // Do some stuff after. return nil }) }
type ConstraintError ¶
type ConstraintError struct {
// contains filtered or unexported fields
}
ConstraintError returns when trying to create/update one or more entities and one or more of their constraints failed. For example, violation of edge or field uniqueness.
func (ConstraintError) Error ¶
func (e ConstraintError) Error() string
Error implements the error interface.
func (*ConstraintError) Unwrap ¶
func (e *ConstraintError) Unwrap() error
Unwrap implements the errors.Wrapper interface.
type Group ¶
type Group struct { // ID of the ent. ID int `json:"id,omitempty"` // Name holds the value of the "name" field. Name string `json:"name,omitempty"` // Edges holds the relations/edges for other nodes in the graph. // The values are being populated by the GroupQuery when eager-loading is set. Edges GroupEdges `json:"edges"` // contains filtered or unexported fields }
Group is the model entity for the Group schema.
func (*Group) QueryUsers ¶
QueryUsers queries the "users" edge of the Group entity.
func (*Group) Unwrap ¶
Unwrap unwraps the Group entity that was returned from a transaction after it was closed, so that all future queries will be executed through the driver which created the transaction.
func (*Group) Update ¶
func (gr *Group) Update() *GroupUpdateOne
Update returns a builder for updating this Group. Note that you need to call Group.Unwrap() before calling this method if this Group was returned from a transaction, and the transaction was committed or rolled back.
type GroupClient ¶
type GroupClient struct {
// contains filtered or unexported fields
}
GroupClient is a client for the Group schema.
func NewGroupClient ¶
func NewGroupClient(c config) *GroupClient

func (*GroupClient) DeleteOne ¶
func (c *GroupClient) DeleteOne(gr *Group) *GroupDeleteOne
DeleteOne returns a delete builder for the given entity.
func (*GroupClient) DeleteOneID ¶
func (c *GroupClient) DeleteOneID(id int) *GroupDeleteOne
DeleteOneID returns a delete builder for the given id.
func (*GroupClient) GetX ¶
func (c *GroupClient) GetX(ctx context.Context, id int) *Group
GetX is like Get, but panics if an error occurs.
func (*GroupClient) Query ¶
func (c *GroupClient) Query() *GroupQuery
Query returns a query builder for Group.
func (*GroupClient) QueryUsers ¶
func (c *GroupClient) QueryUsers(gr *Group) *UserQuery
QueryUsers queries the users edge of a Group.
func (*GroupClient) Update ¶
func (c *GroupClient) Update() *GroupUpdate
