Comment (by [email protected]):
Hm. I probably described this problem badly. If function
''result_headers'' ends on the line 113 (!!!), it returns only dict
{"text": header}. But template ''change_list_results.html'' needs value
''class_attrib''. If this value missing, the html code looks like this:
<thINVALID VARIABLE>. This situation occurs, when the column in the list
is not defined as a field in model but as a function only.
For example:
{{{
#!python
class Person(models.Model):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
def upper_case_name(obj):
return ("%s %s" % (obj.first_name, obj.last_name)).upper()
upper_case_name.short_description = 'Upper Name'
class PersonAdmin(admin.ModelAdmin):
list_display = ("first_name", "upper_case_name")
}}}
And now see title of the column '''Upper Name''' in the person admin list.
Correction is simple: Just add ''if'' to the template
''change_list_results.html'':
{{{
<th{% if header.class_attrib %}{{ header.class_attrib }}{% endif %}>
}}}
I hope, it is clear now.
