我正在尝试用所有记录预填充我的表单,但我收到错误 'QuerySet' object has no attribute '_meta' ,我尝试只通过初始查询集传递我的查询集,而我没有收到错误模板中的栏位没有呈现 initial={runninghours}
我的意见.py:
def runninghours(request):
runninghours = RunningHours.objects.all()
form = RunningHoursModelForm()
form_populated = RunningHoursModelForm(initial={runninghours})
if request.method == 'POST' and 'form-create' in request.POST:
form = RunningHoursModelForm(request.POST)
if form.is_valid():
form.save()
return redirect(request.path_info)
context = {"form": form,
"rhs": form_populated}
return render(request, 'runninghours.html', context)
模板:
<form method="POST" action="">
{% csrf_token %}
<td>{% render_field rhs.name %}</td>
<td>{% render_field rhs.current_runninghours %}</td>
<td>{% render_field rhs.last_runninghours %}</td>
<td>{% render_field rhs.last_modified %}</td>
<td> <input type="hidden" name="update_runninghours_id" value="{{ rhs.pk }}" />
<input name="form-delete" type="submit" class="button1" value='Update Runninghours' /></td>
</form>
模型.py:
class RunningHours(models.Model):
name = models.CharField(max_length=100)
current_runninghours = models.IntegerField(blank=True,null=True)
last_runninghours = models.IntegerField(blank=True,null=True,default=0)
last_modified = models.DateField(("Date"), default=datetime.date.today)
表格.py:
class RunningHoursModelForm(forms.ModelForm):
model = RunningHours
fields = ("name",
"current_runninghours",
"last_runninghours",)

我不认为你可以通过使用 initial.runninghours 来传递查询集。这需要字典作为自变量。您可以做的是使用查询集来制作表单。
# forms.py
class RunningHoursModelForm(ModelForm):
def __init__(self,company,*args,**kwargs):
super (RunningHoursModelForm,self ).__init__(*args,**kwargs)
self.fields['the_field_you_want'].queryset = RunningHours.objects.all()
class Meta:
model = RunningHours
如果你想用 RunningHours 的实体填充表单,你可以这样做
particularRunningHours = RunningHours.objects.get(name=name)
form_populated = RunningHoursModelForm(initial={
'current_runninghours': particularRunningHours.current_runninghours,
...
})
