我想将inlineform中的某些模型字段过滤到特定的用户和公司。
但是无法在Django内联表单集中进行。
这是我的模特
class Purchase(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,null=True,blank=True)
company = models.ForeignKey(Company,on_delete=models.CASCADE,null=True,blank=True)
party_ac = models.ForeignKey(Ledger1,on_delete=models.CASCADE,related_name='partyledger')
purchase = models.ForeignKey(Ledger1,on_delete=models.CASCADE,related_name='purchaseledger')
total = models.DecimalField(max_digits=10,decimal_places=2,null=True,blank=True) purchases
class Stock_total(models.Model):
purchases = models.ForeignKey(Purchase,on_delete=models.CASCADE,null=True,blank=False,related_name='purchasetotal')
stockitem = models.ForeignKey(Stockdata,on_delete=models.CASCADE,null=True,blank=True,related_name='purchasestock')
quantity_p = models.PositiveIntegerField()
rate_p = models.DecimalField(max_digits=10,decimal_places=2)
grand_total = models.DecimalField(max_digits=10,decimal_places=2,null=True,blank=True)
我的观点:
class Purchase_createview(ProductExistsRequiredMixin,LoginRequiredMixin,CreateView):
form_class = Purchase_form
template_name = 'stockkeeping/purchase/purchase_form.html'
def get_context_data(self, **kwargs):
context = super(Purchase_createview, self).get_context_data(**kwargs)
context['profile_details'] = Profile.objects.all()
company_details = get_object_or_404(Company, pk=self.kwargs['pk'])
context['company_details'] = company_details
if self.request.POST:
context['stocks'] = Purchase_formSet(self.request.POST)
else:
context['stocks'] = Purchase_formSet()
return context
def form_valid(self, form):
form.instance.user = self.request.user
c = Company.objects.get(pk=self.kwargs['pk'])
form.instance.company = c
context = self.get_context_data()
stocks = context['stocks']
with transaction.atomic():
self.object = form.save()
if stocks.is_valid():
stocks.instance = self.object
stocks.save()
return super(Purchase_createview, self).form_valid(form)
在我的表单中,我已经尝试过:
class Stock_Totalform(forms.ModelForm):
class Meta:
model = Stock_Total
fields = ('stockitem', 'Quantity_p', 'rate_p', 'Disc_p', 'Total_p')
def __init__(self, *args, **kwargs):
self.User = kwargs.pop('purchases.User', None)
self.Company = kwargs.pop('purchases.Company', None)
super(Stock_Totalform, self).__init__(*args, **kwargs)
self.fields['stockitem'].queryset = Stockdata.objects.filter(User = self.User, Company= self.Company)
self.fields['stockitem'].widget.attrs = {'class': 'form-control select2',}
self.fields['Quantity_p'].widget.attrs = {'class': 'form-control',}
self.fields['rate_p'].widget.attrs = {'class': 'form-control',}
self.fields['Total_p'].widget.attrs = {'class': 'form-control',}
Purchase_formSet = inlineformset_factory(Purchase, Stock_Total,
form=Stock_Totalform, extra=6)
但是,如果存在于特定用户和特定公司下,则对查询集的过滤不会显示任何项目。
任何人都可以帮助我进行准确的查询,该查询将过滤特定用户和公司下的对象。
谢谢

创建queryset
时,您需要删除__init__
格式的instance
并传递inlineformset_factory
参数。
Purchase_formSet = inlineformset_factory(
Purchase,
Stock_Total,
form=Stock_Totalform,
extra=6,
)
PurchaseForm = Purchase_formSet(instance=Stockdata.objects.filter(User='1'))
这是静态方法,这意味着过滤器将是固定的,不会根据用户输入的形式进行更改。
如果您希望基于某些表单字段中的用户输入来进行动态过滤,this article会非常详细地进行解释。
