我最近一直在从事一个项目,并遇到了上述错误。它说“模板渲染期间出错”。我有一个类似的模型,可以很好地工作。我一直在寻找类似的错误,但没有一个适合我的情况。我不知道我哪里出了错。如果我得到有用的答案,那就太好了。
Models.py
class ServiceTax(models.Model):
user = models.ForeignKey(User,on_delete=models.CASCADE,related_name="service_tax",null=True,blank=True)
name=models.CharField(max_length=100)
percent=models.FloatField(default='0')
add_amount=models.IntegerField(default='0')
def __str__(self):
return self.name
Forms.py
class ServiceTaxForm(forms.ModelForm):
class Meta:
model = ServiceTax
fields = "__all__"
widgets = {
'name' : forms.TextInput(attrs={'class': 'form-control'}),
'percent' : forms.NumberInput(attrs={'class': 'form-control','step':'0.01'}),
'add_amount' : forms.NumberInput(attrs={'class':'form-control','maxlength':5}),
}
labels={
'add_amount': "Additional Amount"
}
Views.py
def tax_form(request,id=0):
if request.method == 'GET':
if id == 0:
form = ServiceTaxForm(request)
else:
tax = ServiceTax.objects.get(pk=id)
if tax in request.user.service_tax.all():
form = ServiceTaxForm(request,instance=tax)
else:
return redirect('/revenue/tax')
return render(request,'tax-form.html',{'form':form})
else:
if id==0:
form = ServiceTaxForm(request,request.POST)
if form.is_valid():
name = form.cleaned_data["name"]
percent = form.cleaned_data["percent"]
add_amount = form.cleaned_data["add_amount"]
t = AnnualTax(
name=name,
percent=percent,
add_amount=add_amount,
)
t.save()
request.user.service_tax.add(t)
else:
tax = ServiceTax.objects.get(pk=id)
if tax in request.user.service_tax.all():
form = ServiceTaxForm(request,request.POST,instance=tax)
if form.is_valid():

percent = form.cleaned_data["percent"]
add_amount = form.cleaned_data["add_amount"]
tax_obj = ServiceTax.objects.get(pk=id)
tax_obj.name = name
tax_obj.percent = percent
tax_obj.add_amount = add_amount

答案 0 :(得分:0)
您应该检索通过 request.METHOD 的表单,而不仅仅是请求
作为示例,这段代码form = ServiceTaxForm(request)
应该为form = ServiceTaxForm(request.POST)
