Idiomatic way to update with GORM and echo-framework - go

Question

Hi new in golang and trying to make rest API
I want to updating entity passing only needed datas with GORM and golang echo framework.
And I get this error :
"strconv.ParseUint: parsing \"ea78944c-a2a9-4813-86e7-10b199d0f002\": invalid syntax"
I use echo.Bind() func to bind formdata (I use postman) with my Club struct.
PS : I use xid to external id and keep my int id to interne work.
Expected :
I'm gonna find Club in my database by id (get with url param) with GORM and set it up in a new club struct.
After that, I bind my club struct with my formdata.
And finally save it with Save() GORM func. => get error
Reality :
I'm gonna find Club in my database by id (write hardcoding string id) with GORM and set it up in a new club struct.
After that, I bind my club struct with my formdata.
And finally save it with Save() GORM func. => works
Conclusion :
I don't know how to pass url parameter AND formdata in PUT method using echo.Bind()
Here my Club struct :
// Club struct
type Club struct {
Base
Name string `json:"name;" gorm:"type:varchar(255);not null" validate:"required"`
Slug string `json:"slug;" gorm:"type:varchar(255);unique;not null"`
Website string `json:"website;" gorm:"type:varchar(255)"`
Lat float32 `json:"lat;" gorm:"lat;" sql:"type:decimal(8,6);" validate:"required,numeric"`
Lng float32 `json:"lng;" gorm:"lng;" sql:"type:decimal(9,6);" validate:"required,numeric"`
Logo string `json:"logo;" gorm:"type:varchar(100)" validate:"required"`
Phone string `json:"phone;" gorm:"type:varchar(20)" validate:"required"`
}
My FindById func :
// GetClubByXID get club by xid
func GetClubByXID(c echo.Context, xid string) (*schemas.Club, error) {
club := new(schemas.Club)
if result := db.Where("xid = ?", xid).First(&club); result.Error != nil {
return nil, result.Error
}
return club, nil
}
And here my updating func :
func UpdateClub(c echo.Context) error {
xid := c.Param("id") // => doesn't work
// xid := "ea78944c-a2a9-4813-86e7-10b199d0f002" // => work
club, err := models.GetClubByXID(c, xid)
if err != nil {
return c.JSON(http.StatusNotFound, err)
}
if err := c.Bind(club); err != nil {
return c.JSON(http.StatusInternalServerError, err)
}
db.Save(&club)
return c.JSON(http.StatusOK, echo.Map{
"club": &club,
})
}
My updating route :
API.PUT("/updateClub/:id", handlers.UpdateClub) // => doesn't work
// API.PUT("/updateClub", handlers.UpdateClub) // => work
When I write with hardcoding my xid ea78944c-a2a9-4813-86e7-10b199d0f002 in my updating func it's work like a charm but I can't combine my url and my formdata with echo.Bind()
my err if I try http://localhost:1323/api/updateClub/ea78944c-a2a9-4813-86e7-10b199d0f002:
"strconv.ParseUint: parsing \"ea78944c-a2a9-4813-86e7-10b199d0f002\": invalid syntax"
Thanks for reading hope someone can help me :)

Answer 1

Can you try to c.Param("xid") instead of c.Param("id") and change the routing parameter as API.PUT("/updateClub/:xid", handlers.UpdateClub)
