#26819: Using a ArrayField on Meta.unique_together throws "unhashable type: 'list'"
on validate_unique method

It happens on a second save (when there is already data to be validated)

On this line: "if row_data in seen_data:", because row_data contains a
list and seen_data is a set (row_data: (1, [1, 1]) / seen_data: set())

Example to reproduce:

models:
{{{#!python
class Map(models.Model):
name = models.CharField(_('name'), max_length=128)

class MapSpot(models.Model):
map = models.ForeignKey('body.Map', related_name='spots')
position = ArrayField(models.IntegerField(), size=2)

class Meta:
unique_together = [('map', 'position')]
}}}

admin:
{{{#!python
class MapSpotInline(admin.TabularInline):
model = MapSpot
extra = 0

@admin.register(Map)
class MapAdmin(admin.ModelAdmin):
inlines = [MapSpotInline]
}}}

You have to replace 'body.Map' with the app name you are using
('polls.Map' apparently)

Thanks. That worked.
I was able to build the models, now when I try logging to my admin it
throws this error.
Not sure if you had the same problem.

You need to run migrate command to create database tables

Comment (by PREM1980):

This issue occurs as the array item is stored in the lists and there is a
mis-match while comparison.

The arrayitem is stored in row_data as list and list are not hashable as
the error says.

if row_data in seen_data:

This issue can be fixed by changing this line ie; return a tuple instead
of list.

Please review and provide your comments.

Comment (by timgraham):

Not sure without looking into the details myself, but it might be better
if the `validate_unique()` method took care of casting as needed since
changing the return value of `to_python()` could be backwards-
incompatible.

Comment (by PREM1980):

As you mentioned, implemented fix in validate_unique() method. The above
code fixes the issue and all the unit tests got passed.

The only problem is Im not sure how to write the test case. It needs to be
simulated as if a user creates a form in the html page. Do you have any
pointers for testing similar condition?

row_data = tuple(d._get_pk_val() if hasattr(d, '_get_pk_val') else
tuple(d)
if type(d) is list else d for d in
row_data)

Take a look at `tests/postgres_tests/test_array.py` for the existing tests
for `ArrayField`.

By the way, you inadvertently deleted the ticket's description in your
last comment. Can you restore it? Deleting your comment should undo that
action if you can't find another way.

Comment (by Meiyer):

This happens only for Inline admin models (only `validate_unique()` of
`BaseModelFormSet` contains the problematic code).

This is not limited to `ArrayField`; any custom field may be affected. In
our case, the `phonenumber_field.modelfields.PhoneNumberField` is causing
the error `unhashable type: 'PhoneNumber'`. Since Django documentation
does not mandate that custom fields are hashable (i.e., define the
`__hash__()` method), I suppose that most of the existing non-builtin
fields are affected.

Looks like the solution is either to keep `seen_data` as a `set()` and
rely on some property of the field (unreliable and error-prone, see sample
code below), or give up `set()` and manually implement removal of
duplicates.

{{{

row_data = tuple(d._get_pk_val() if hasattr(d, '_get_pk_val') else

d if d.__hash__ is not None else
d.__repr__()
for d in row_data)
}}}

Comment:

I believe it affects all inline formsets, not just those in the admin.
There's a [https://github.com/django/django/pull/7094 PR] without tests.
