Comment (by kmtracey):
I can recreate a problem, not entirely sure it is exactly what was
originally reported. Given these models:
{{{
#!python
class FCollection(models.Model):
name = models.CharField(max_length=22)
def __unicode__(self):
return self.name
class FileT(models.Model):
coll = models.ForeignKey(FCollection)
rating = models.IntegerField()
ifile = models.ImageField(upload_to=u'uploaded_files')
def __unicode__(self):
return u'%s: %s' % (unicode(self.coll), self.ifile)
}}}
and this admin.py:
{{{
#!python
class FileTInline(admin.TabularInline):
model = FileT
class FCollectionAdmin(admin.ModelAdmin):
inlines = [FileTInline]
admin.site.register(FCollection, FCollectionAdmin)
}}}
Recreate by first creating an FCollection and uploading one file. Then,
attempt to add a 2nd, but only fill in the rating, don't actually upload a
file. Upon hitting any of the save buttons, the page will get re-
displayed with the "This field is required" and "Please correct the error
below" messages (both fine), but also the widget for the 1st file will no
longer show that the first inline object has an associated file. That is,
it will no longer have "Currently: whatever_file_name" nor the "Change:"
label next to the file chooser input box.
So, I see that the existing data for the already-uploaded file fields
appears to vanish, but I'm not sure if there was more vanishing going on
in the original report which says "wipes out all the previous data". It's
only the existing file field data that isn't displayed, the rest of the
fields display properly. Also it is just that the data is not being
shown, it hasn't been lost: if you go back and reload the page from
scratch or fix the required error by choosing a file to upload and saving,
then again all of the uploaded file information is displayed on the page.
