使用 gorm 查询字符串数组

Question

I'm trying to select items of a table with a column of type text[] . The result of the field brandIds always return null

my struct:

type User struct {
    Email    string         `json:"email"`
    Name     string         `json:"name"`
    BrandIds pq.StringArray `gorm:"type:text[]" json:"brandIds"`
}

the code:

        var users []dtos.User
        db.Table("user").Find(&users)
        data, _ := json.Marshal(users)

Name and emails returns fine... But the brandIds always return null. Type of brandIds column is text[]

Answer 1

Postgres have some troubles with camelCase column names. When I named BrandIds gorm was looking for column bran_id

I needed to specify the column name so I have added the gorm:"column:brandId" to tell gorm whats the name of the column.
