Comment (by Christophe Henry):

 Replying to [comment:4 Natalia Bidart]:

 > And in my template, the correct help text is shown at all times

 That's because when you do {{{ self.fields["foo_select"].help_text =
 f"Indicate {user.first_name}'s pet name" }}}, at this stage,
 [https://github.com/django/django/blob/main/django/forms/forms.py#L104
 self._bound_fields_cache] may not be populated. But if you do the
 following:

 {{{#!python
 class FooForm(forms.Form):
     foo_select = forms.CharField()
     ...  # Other fields

     def __init__(self, user, *args, **kwargs):
         super().__init__(*args, **kwargs)
         # candid dev not knowing the difference between self[] and
 self.fields[]
         # setting avariable for every field
         for field in self:
             field.should_do_something = False
         self.fields["foo_select"].help_text = f"Indicate
 {user.first_name}'s pet name"

         # demonstration
         assert self["foo_select"].help_text ==
 self.fields["foo_select"].help_text
 }}}

 Please don't tell me this is not a valid situation. This happened to me on
 a project recently and I got a hard time tracking down why this happened.
