我有以下模型,我从中创建了一个ModelForm。 我包含了save_m2m,因为在我提交表单时它没有保存多个字段。 我还使用2个不同的视图来创建或更新,因为我认为这是导致创建新记录的原因。
但是,它不是更新实例,而是创建一个新实例。 那么如何编辑包含多个到多个字段的模型数据呢?
models.py
class GeneralContract(models.Model):
idcontract = models.IntegerField(primary_key=True)
client=models.ForeignKey(Person)
issuedate = models.DateTimeField() # Field name made lowercase.
plan = models.ManyToManyField(Generalbusinessplans)
annualpremium = models.FloatField() # Field name made lowercase.
doses = models.IntegerField(blank=True, null=True)
views.py
def addContractGeneralView(request):
added=False
if request.method == 'POST':
contract_form = GeneralContractForm(request.POST)
if contract_form.is_valid():
profile = contract_form.save(commit=False)
p = Person.objects.get(idperson=contract_form.cleaned_data['client'].idperson)
print p
if p.isclient == 0:
print 'in if'
p.isclient = 1
p.save()
profile.save()
contract_form.save_m2m()
print profile.plan
added = True
else:
print contract_form.errors
else:
contract_form = GeneralContractForm()
return render(request,
'leadsMasterApp/addContractGeneral.html',
{'add_contract_form':contract_form,'added': added})
def editContractGeneralView(request,pk):
instance=get_object_or_404(GeneralContract, pk=pk)
added=False

if contract_form.is_valid():
profile = contract_form.save(commit=False)

print p
if p.isclient == 0:
print 'in if'
p.isclient = 1
p.save()
profile.save()
contract_form.save_m2m()
