Introduction
warning
Note that this feature is only effective for chaining operations.
The gdb
module supports the automatic filling of creation, update, and deletion times for data records, improving development and maintenance efficiency. To facilitate unified maintenance of time field names and types, if using this feature, we have the following conventions:
- The field type can be a time type, numeric integer, or boolean, such as:
date
,datetime
,timestamp
,int
,uint
,big int
,bool
, etc. - Field names can be customized, with default naming conventions being:
created_at
is updated during record creation and is only written once.updated_at
is updated during record modification and is updated each time the record changes.deleted_at
is for the soft delete feature of the record and is only written once when the record is deleted. Field names are case-insensitive and ignore special characters, for example,CreatedAt
,UpdatedAt
,DeletedAt
are also supported.
Feature Configuration
Time field names can be customized in the configuration file, and the feature can be completely disabled on the database instance using the timeMaintainDisabled
configuration.
Corresponding configuration items in the configuration file:
database:
default: # Group name, customizable, default is "default"
createdAt: "created_at" # (Optional) Auto-create time field name
updatedAt: "updated_time" # (Optional) Auto-update time field name
deletedAt: "is_deleted" # (Optional) Soft delete time field name
timeMaintainDisabled: false # (Optional) Whether to completely disable the time update feature. If true, CreatedAt/UpdatedAt/DeletedAt will be ineffective
tip
Especially for historical projects, where different time field names already exist, the time field names can be flexibly configured using configuration items.
For a complete database configuration, please refer to the ORM - Configuration section.
Feature Activation
When a data table contains any or multiple fields such as created_at
, updated_at
, deleted_at
, or contains corresponding configuration fields in the configuration file, this feature is automatically enabled.
