Description
If you define the following field:
tags = meta.ManyToManyField(Tag, blank=True, raw_id_admin=True)
And provide no input for the 'tags' field in the HTML form for the addition of the given model. You get this error (although blank=True should cause it to work fine):
There's been an error: Traceback (most recent call last): File "d:\django\django\core\handlers\base.py", line 64, in get_response response = callback(request, **param_dict) File "i:\projects\grono2\contrib\web\create_update.py", line 51, in create_object new_object = manipulator.save(new_data) File "d:\django\django\utils\functional.py", line 3, in _curried return args[0](*(args[1:]+moreargs), **dict(kwargs.items() + morekwargs.items())) File "d:\django\django\core\meta\__init__.py", line 1483, in manipulator_save was_changed = getattr(new_object, 'set_%s' % f.name)(new_data.getlist(f.name)) File "d:\django\django\utils\functional.py", line 3, in _curried return args[0](*(args[1:]+moreargs), **dict(kwargs.items() + morekwargs.items())) File "d:\django\django\core\meta\__init__.py", line 896, in method_set_many_to_many id_list = map(int, id_list) # normalize to integers ValueError: invalid literal for int():

Here's how Tag looks. Default primary key.
class Tag(meta.Model): name = meta.CharField('name', maxlength=150, unique=True) user = meta.ForeignKey(User) # typ taga, 0 - generyczny, reszta do zarezerwowania type = meta.IntegerField(default = 0) added = meta.DateTimeField('added', auto_now_add=True)

I've verified that this works properly (with no error) using current post-magic-removal trunk.
Note:
See TracTickets
for help on using tickets.
Is the primary key in your
Tag
model a non-integer? If so, this is a known issue, and I have a fix on my local machine.
