The first parameter is the request path, and the second parameter is the http status code.
C.Redirect ("/ login", 400) / / Redirect c.TplName = "login.html" model creation
Set the primary key `pk`
Set self-increment `auto`
Note: when the Field type is int,int32,int64,uint,uint32,uint64, you can set the field to self-augmentation, and when there is no primary key in the model definition, the Field with the name Id that matches the above type will be regarded as self-augmentation.
Set the default value `default (1111) `
Set the long length `orm:size (100) `
The setting is allowed to be empty `null`, and the database is not empty by default. After setting null, it can be changed to `null`.
Set unique `orm: "unique" `
Set floating point precision `orm: "digits (12); decimals (4)" `/ / A total of 12 digits, with four decimal places
Set time `orm: "auto_now_add;type (datetime)" `
`orm: "auto_now;type (date)" `
Note:
Auto_now automatically updates the time every time model is saved.
Auto_now_add only sets the time when it is saved for the first time
Format the time: type
