mysql - How can I set COLLATION of a field to utf8_general_ci with GORM? -

-

i have string-type field in mysql database case-insenstive , unique. used following model:

type user struct {     id             int64  `json:"id" sql:"auto_increment"`     email          string `json:"email" sql:"unique_index"` }

which makes email unique, 

type user struct {     id             int64  `json:"id" sql:"auto_increment"`     email          string `json:"email" sql:"unique_index;collation(utf8_general_ci)"` }

seems have no effect.

how can set collation of field utf8_general_ci gorm?

you can use sql tag in field want change, this:

type user struct {     gorm.model     name `sql:"type:varchar(5) character set utf8 collate utf8_general_ci"` }
