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

I would like a string-type field in a MySQL database which is case-insignificant and unique. I use the following model:

  type user string {id} 64 json: "id" sql: "AUTO_INCREMENT" `email string 'json:" email "sql:" unique_index "` }  

which makes email unique, but

  type user structure {id int64 `json:" id "sql: "AUTO_INCREMENT" `Email String` json:" email "sql:" Unique_index; COLLATION (utf8_general_ci) "`}  

has no effect.

How can I set COLLATION to the field for the utf8_general_ci with GOM?

You can use the SQL tags in the area that you want to change, like this:

  type user structure {gorm.Model name `sql:" type: VARCHAR (5) character set UTF8 COLLATE utf8_general_ci "`}
