Gorm 未读取 select 上的列

Question

I'm running a SELECT using WHERE on gorm but the results are comming with the columns store_name and type empty(""). I have the following struct on Go:

type Store struct {
      ID        uint
      StoreName string
      Type      string
      Code      string `gorm:"unique"`
      Active     bool
      CreatedAt *time.Time
      UpdatedAt *time.Time
}

The following database on Postgres:

CREATE TABLE IF NOT EXISTS stores
(
    id                  BIGSERIAL       PRIMARY KEY,
    store_name          TEXT            NOT NULL,
    type                TEXT            NOT NULL,
    code                TEXT            NOT NULL UNIQUE,
    active              BOOLEAN         DEFAULT true,
    created_at          TIMESTAMPTZ     NOT NULL DEFAULT NOW(),
    updated_at          TIMESTAMPTZ
);

Im running this select right here:

    var store Store

    result := db.First(&stores).Where("code = ?", code)
    if err := result.Error; err != nil {
          return nil, err
    }

    return &stores, nil

Does anyone know what I may be doing wrong? All columns are returned on the SELECT except for the columns StoreName and Type. Thank you so much in advance!

You need to set the field tag if field name differs from DB column name.

Example:

StoreName string `gorm:"column:store_name"`
