I have a model with DateTime field. I want to set initials for this field
in django admin by using query params. For example:
{{{
# models.py
class MyModel(models.Model):
created_at = models.DateTimeField()
# admin.py
@admin.register(MyModel)
class MyModelAdmin(admin.ModelAdmin):
pass
}}}
Trying to create new object of MyModel with initial for created)at field:
`http://127.0.0.1:8000/admin/myapp/mymodel/add/?created_at=2024-10-10%2005%3A57%3A31`
Admin sites crashes with 500 error. This happens because the method
`decompress` of the `SplitDateTimeWidget` expects an object of datetime
type, but it is passed the string instead.
Proposed fix:
{{{
def decompress(self, value):
if isinstance(value, str):
try:
value = datetime.fromisoformat(value)
except ValueError:
return [None, None]
if value:
value = to_current_timezone(value)
return [value.date(), value.time()]
return [None, None]
}}}
