Question: How to use i18n with complex fields in ModelAdmin

I extend the cms using ModelAdmion. Everything is fine but i did not get the labels beeing translated.

class Person extends DataObject {
...
    private static $has_one = array(
		'myImage' => Image::class
    );
...
}

In my de_DE.yml I have the following variables:

de_DE:
  Person :
    db_myImageID: Bild1
    db_myImage: Bild2
    myImage: Bild2

But the translated title is not shown in cms if i create a new record. Instead there is “My Image” as caption of the UploadField. Any ideas?

Best regards,

The static variable field_names ist set

     private static $field_labels = [
        'Image.Title' => 'to-be-changed-via-i18n',
        ];

There is a function in DataObject

    public function fieldLabels($includerelations = true)    {
        ...
    }

which looks only for the has_one-relations if the parameter $includerelations is set to true. Unfortunately, the relevant call for my DataObject sets it to false. Any ideas, how to get the field-labels for the has_one-relations too before looking for the second solution = overriding?

The db_ prefix works only with bare fields. Try this instead:

de_DE:
  Person :
    has_one_myImage: Bild1

See the DataObject::fieldLabels for the other possible prefixes.

If you need more control (e.g. you want to build the label dynamically), you can also override that method in your DataObject.
