Not able to make fields readonly in edit mode

[aniruddha-mmt-zz]

Hi Jinzhu and team. Awesome product to make the life of go developers easy especially which came from python/Django background. I'm stuck while trying to make some of my model fields read-only i.e. once saved, the fields should not be allowed for editing. Please help or suggest any other way.

Configuring the meta type as read-only does not work for you?

Than you might have to work with custom Setter to ignore the updates. https://doc.getqor.com/admin/fields.html

Type as read-only won't help me because my use case is once a user enters a value and save, it should become un-editable. I have gone through the whole doc but not able to find any specific custom type, could you please share some sample code snippet.

Search for virtual field in the link I posted. There you will find this code for passwords.

user.Meta(&admin.Meta{Name: "Password",
    Type:   "password",
    Valuer: func(interface{}, *qor.Context) interface{} { return "" },
    Setter: func(record interface{}, metaValue *resource.MetaValue, context *qor.Context) {
        if newPassword := utils.ToString(metaValue.Value); newPassword != "" {
            bcryptPassword, _ := bcrypt.GenerateFromPassword([]byte(newPassword), bcrypt.DefaultCost)
            record.(*models.User).EncryptedPassword = string(bcryptPassword)
        }
    },
})

for your application, I'd just check if the value was previously saved and discard any changes. This won't make it disabled in the HTML, though.
