django-smart-select with django-material

Hi

I had a look at issue #170 and have the same problem. I tried the workaround that was suggested, but unfortunately it does not work on the admin side. Everything works perfectly when django-material is disabled. I know the bug is not on your side, but it would be great if smart-selects would be able to work with django-material. Any help would be appreciated

Here is my model, the referenced foreignkey is in a different app and like I said smart-selects works without django-material enabled.

class Stock(models.Model):
	StockNumber = models.CharField(max_length=20, blank=True)
	MMCode = models.ForeignKey('mead.VehicleMM', related_name='vehicle')
	Year = ChainedForeignKey('mead.VehicleValue', chained_field="MMCode", chained_model_field="MMCode", show_all=False, auto_choose=True, sort=True)
	EngineNumber = models.CharField(max_length=50, verbose_name='Engine Number')
	VINNumber = models.CharField(max_length=50, verbose_name='VIN Number')
	RegistrationNumber = models.CharField(max_length=50, verbose_name='Registration Number')
	Colour = models.CharField(max_length=50)
	Mileage = models.IntegerField()
	FuelType = models.CharField(max_length=2, choices=FUEL_CHOICES, verbose_name='Fuel Type')
	NonFactoryAccessories = models.TextField(blank=True, verbose_name='Non Factory Accessories')
	PurchasePrice = models.DecimalField(max_digits=20, decimal_places=2)
	PaymentRemittanceNumber = models.CharField(max_length=100, blank=True, verbose_name='Payment Remittance Number')
	From = models.CharField(max_length=100, verbose_name='Vehicle Bought From')
	RetailValue = models.DecimalField(max_digits=20, decimal_places=2, null=True)
	ProfitMargin = models.DecimalField(max_digits=20, decimal_places=2, null=True)
	PurchaseDate = models.DateField()
	StandInValue = models.DecimalField(max_digits=20, decimal_places=2, null=True)
	NumberOfStockDays = models.IntegerField(null=True, verbose_name='Number of days in stock')
	SpareKeys = models.BooleanField(default=False)
	TrackingInstalled = models.BooleanField(default=False)
	SpareWheel = models.BooleanField(default=False)
	Jack = models.BooleanField(default=False)
	Tools = models.BooleanField(default=False)
	ServiceBooks = models.CharField(max_length=2, choices=SERVICE_CHOICES)
	Natis = models.FileField(upload_to='natis')
	LicenseRenewalDate = models.DateField()
	ServiceIntervals = models.CharField(max_length=100)
	NextServiceDueDate = models.DateField()
	NextServiceDueMileage = models.IntegerField()
	Status = models.CharField(max_length=2, choices=STATUS_CHOICES)

admin.py

class StockAdminForm(forms.ModelForm):
	class Meta:
		model = Stock
		widgets = {'Year': YearWidget(attrs={'to_app_name': 'stock',
											'to_model_name': 'Stock',
											'chained_field': 'MMCode',
											'chained_model_field': 'MMCode',
											'foreign_key_app_name': 'mead',
											'foreign_key_model_name': 'VehicleValue',
											'foreign_key_field_name': 'MMCode',
											'show_all': False,
											'auto_choose': True})}

@admin.register(Stock)
class StockAdmin(admin.ModelAdmin):
	list_display = ['StockNumber', 'Status']
	list_filter = ['Status',]
	search_fields = ['StockNumber',]
	raw_id_fields = ['MMCode',]
	form = StockAdminForm

widget.py as suggested workaround

from smart_selects.widgets import ChainedSelect

class YearWidget(ChainedSelect):
    def __init__(self, *args, attrs=None, **kwargs):
        self.attrs = attrs
        super(YearWidget, self).__init__(*args, **kwargs)
    
    def render(self, *args, **kwargs):
        super(YearWidget, self).render(*args, attrs=self.attrs, **kwargs)

The error I receive from shell

TypeError: init() missing 9 required positional arguments: ‘to_app_name’, ‘to_model_name’, ‘chained_field’, ‘chained_model_field’, ‘foreign_key_app_name’, ‘foreign_key_model_name’, ‘foreign_key_field_name’, ‘show_all’, and ‘auto_choose’

I don’t want to complicate the code in django-smart-selects any more than it already is (it’s brittle enough already), so I will not be fixing this.

The proper fix is to get django-material to properly render widgets as I noted in my comment on #170.

Sorry!
