✅

The many ways to do it exists.

Django documentation way:

class DnaSequence(AbstractBioSequence):
    some_dna_field = models.TextField()
    description = models.CharField(max_length=1000, null=True, blank=True, help_text=_("DnaSequence specific helper text"))

don’t forget to makemigrations, your help_text should be added to migration schema.

Monkey-Patcher way:

class DnaSequence(AbstractBioSequence):
    some_dna_field = models.TextField()

DnaSequence._meta.get_field('description').help_text = _("DnaSequence specific helper text")

In earlier version it was get_field_by_name method. More about it: https://docs.djangoproject.com/en/4.1/ref/models/meta/#django.db.models.options.Options.get_field

In this art of changes you shouldn’t get any migration.

Other ideas:

  1. You can override form field help text. It works good for
    ModelAdminForm. More here: https://docs.djangoproject.com/en/4.1/topics/forms/modelforms/#overriding-the-default-fields
  2. You can create you own help_text_model, and add help_text on-fly to field with Mixin.
  3. Many other ways…
