Description
I'm using Django Version 1.7c2 and I have these two models :
class Module(models.Model): name = models.CharField(max_length=255) class Subject(models.Model): module = models.ForeignKey(Module)
And this Admin Class:
class SubjectAdmin(admin.ModelAdmin): search_fields = ('module__name',)
And i'm getting this error
FieldError at /admin/app/subject/
Relation fields do not support nested lookups
on django\db\models\fields\related.py in get_lookup_constraint
raise exceptions.FieldError('Relation fields do not support nested lookups')

I have a similar issue, except that my model is slightly more complex. The Module
class inherit from another one, and I use a ManyToManyField
, instead of a ForeignKey
.
class Base(models.Model): name = models.CharField(max_length=100) class Module(Base): pass class Subject(models.Model): module = models.ManyToManyField(Module)
The admin class is still the same :
class SubjectAdmin(admin.ModelAdmin): search_fields = ('module__name',)
When I try to search, I get this issue :
Django Version: 1.6.5 Exception Type: TypeError Exception Value: Related Field got invalid lookup: icontains Exception Location: /usr/local/lib/python2.7/dist-packages/django/db/models/fields/related.py in get_lookup_constraint, line 1123 Python Executable: /usr/bin/python Python Version: 2.7.6
By the way, I run Django 1.6.5, I did not test my project under django 1.7.

Replying to ramiro:
I can't reproduce this with the information provided and using a simple setup containing only the code shown by the OP.
Reopne if you can post more details.
I discovered the problem seems to be related to this ticket: #23697
If using this: search_fields = ('module__name',)
but name
does not exist in the module
model, this error is thrown.
Using django 1.7.3
