#14355: "readonly" fields don't display their "help_text" in admin
----------------------------------+-----------------------------------------
Reporter: jester | Owner: nobody
Status: new | Milestone:
Component: django.contrib.admin | Version: 1.2
Keywords: readonly help_text | Stage: Unreviewed
Has_patch: 0 |
----------------------------------+-----------------------------------------
== Steps to reproduce ==
1. Define a Model, whose field(s) specify `help_text`, e.g.:
{{{
class MyModel(Model):
my_regular_field = CharField(max_length=255, help_text="this is my
regular field")
my_readonly_field = CharField(max_length=255, help_text="this is my
readonly field")
}}}
2. Define a ModelAdmin for your Model, including one of its fields in
`readonly_fields`, e.g.:
{{{
class MyModelAdmin(ModelAdmin):
fields = 'my_regular_field', 'my_readonly_field'
readonly_fields = 'my_readonly_field',
admin.site.register(MyModel, MyModelAdmin)
}}}
In the object view/edit screen, "My regular field" will have help text,
"My readonly field" will not.
== Expectation ==
The expected behavior is that readonly fields will work just like
"regular" fields, except their widget will be their plain value rather
than a form element -- i.e., any string specified as "help_text" should be
displayed after the field.
== Uneducated guesswork ==
I don't dig very deep into the workings of the admin very often, and so,
obviously, what I'm about to say may be entirely unhelpful. However, it
appears that `helpers.AdminReadonlyField` constructs a limited, faux field
object, a dict, at `self.field`, rather than assign the appropriate
BoundField instance. This is perhaps because readonly fields are not
available to it in `self.form.fields`. In the template,
`field.field.field.help_text` fails, as the dict does not contain
"help_text", (and I'm not sure where AdminReadonlyField would get it,
anyway).
