add help text for OneToOneField

Question

I want to add a help_text to a field in my admin create for a model. I already tried what is suggested here.

models.py:

class Product(models.Model):
    name = ...
    ean = models.OneToOneField(EANCode, on_delete = models.CASCADE, help_text = "from model, not visible ...")

forms.py:

class ProductAdminForm(forms.ModelForm):
    class Meta:
        model = Product
        fields = '__all__'
        help_texts = {"name": "this is visible", 
                      "ean": "this is not visible"}

So I can add a helptext to a CharField but not to a OneToOneField. Why?

Answer 1

This would be a bit of a workaround, but you can change how the field names show up in the admin by using verbose_name

    ean = models.OneToOneField(EANCode, on_delete = models.CASCADE, verbose_name = "EAN - not visible")
