I have what must be a common problem: there are three master files,
and a transaction in my admin site involves selecting an item from
each of these files. The field in the Transaction table is a foreign
key pointer to the master file's record. The default admin display
condition in the add/change form is that the dropdown boxes for
selecting the master file items only show an ugly "<tablename> object"
label that is the same for all the choices so the user doesn't know
which to select. The field in the Transaction table is a foreign key
pointing to Person, for example, so the admin is not displaying data
from the Person record referenced by the choice in the dropdown
selection, it only shows that the choice is a Person object. I want a
master table field value for each of the choices to be displayed, e.g.
the value for Person.name, instead of "Person object". What's the way
to make this happen? I've tracked the code that generates the drop-
down html <option> tag to mysite/templates/admin/edit_inline/
fieldset.html, line 12: ... {{ field.label_tag }}{{ field.field }}
where field is an item in "line" which is an item in "fieldset" . I've
tried a bunch of different ways to use fieldsets = [...] in
TransactionAdmin(admin.ModelAdmin) but I keep getting errors that
claim my fields are not valid fields, although they are clearly
defined in models.py and work fine otherwise when I remove the
"fieldset= line[]". I have tried using raw_id_fields but this has no
apparent effect, presumably because it's for list_displays not add/
change forms.
So, what's the right way to do this?
Thanks for helping me!

Showing the problem:
One of the master tables is called "unit", so here is the code django
is generating (note the "unit object" text that is the displayed
choices.)
<div class="form-row unitID "><div>
<label for="id_unitID" class="required">UnitID:</label>
<select name="unitID" id="id_unitID">
<option value="">---------</option>
<option value="1">unit object</option>
<option value="2" selected="selected">unit object</option>
</select><a href="../../../avails/unit/add/" class="add-another"
id="add_id_unitID" onclick="return showAddAnotherPopup(this);"> <img
src="/media/img/admin/icon_addlink.gif" width="10" height="10"
alt="Add Another"/></a></div></div>
