Getting Data in PostgreSQL Gorm-CodePudding

I Have my model as follows:

package models

type Guild struct {
    Id               string `json:"id" gorm:"primaryKey"`
    DefaultBitrate   string `json:"defaultBitrate"`
    DefaultState     string `json:"defaultState"`
    DefaultCategory  string `json:"defaultCategory"`
    DefaultUserLimit int    `json:"defaultUserLimit"`
    HelpChannel      string `json:"helpChannel"`
}

Functions File:

func (h handler) CreateGuild(guildid string) error {
    guild := &models.Guild{
        Id:             guildid,
        DefaultBitrate: "64",
    }
    if result := h.DB.Create(&guild); result.Error != nil {
        return result.Error
    }
    return nil
}
func (h handler) GetGuild(guildid string) (models.Guild, error) {
    var guild models.Guild
    if result := h.DB.First(&guild, guildid); result.Error != nil {
        return guild, result.Error
    }
    return guild, nil
}

So What i do is i create a guild first and then try to get it with the same id yet i don't get anything logged in the console

Database := db.Init()
    h := dbhandlers.New(Database)
    data, err := h.GetGuild("71728137382983743892")
    fmt.Print(data.DefaultBitrate)

Note: I have already created the guild as such:

 err := h.CreateGuild("71728137382983743892")

CodePudding user response：

When using First with non-number primary keys you need to explicitly specify the column against which you want to match the primary key.

Official docs:

If the primary key is a string (for example, like a uuid), the query will be written as follows:
db.First(&user, "id = ?", "1b74413f-f3b8-409f-ac47-e8c062e3472a")
// SELECT * FROM users WHERE id = "1b74413f-f3b8-409f-ac47-e8c062e3472a";

So in GetGuild this:

h.DB.First(&guild, guildid)

should be this:

h.DB.First(&guild, "id = ?", guildid)
