当我试图将内联表单集转换为至少需要第一行时,出现上述错误。(please see here for the StackOverflow question)
我现有的代码如下:
#views.py
def application(request, job_id):
job = get_object_or_404(Job, pk=job_id)
#return 404 if job isn't yet published
if (job.pub_date>timezone.now() or job.close_date<timezone.now()):
return HttpResponseNotFound('<h1>Job not found</h1>')
#create all the inlineformsets (can_delete) set to false as will always be empty upon population
EducationInlineFormSet = inlineformset_factory(Applicant, Education, extra=1, can_delete=False)
QualificationInlineFormSet = inlineformset_factory(Applicant, Qualification, extra=1, can_delete=False)
EmploymentInlineFormSet = inlineformset_factory(Applicant, Employment, extra=1, can_delete=False)
if request.method == 'POST':
applicant = Applicant(job=job)
form = ApplicantForm(request.POST, instance=applicant)
bottom_form = ApplicantFormBottom(request.POST, instance=applicant)
education_formset = EducationInlineFormSet(request.POST, instance=applicant)
qualification_formset = QualificationInlineFormSet(request.POST, instance=applicant)
employment_formset = EmploymentInlineFormSet(request.POST, instance=applicant)
#check all of the forms and formsets are valid
if form.is_valid() and bottom_form.is_valid() and education_formset.is_valid() and qualification_formset.is_valid() and employment_formset.is_valid():
# save the model to database, directly from the form:
form.save()
bottom_form.save()
education_formset.save()
qualification_formset.save()
employment_formset.save()
return render(request, 'jobs/success.html')
else:
applicant = Applicant(job=job)
form = ApplicantForm(instance=applicant)
bottom_form = ApplicantFormBottom(instance=applicant)
education_formset = EducationInlineFormSet(instance=applicant)
qualification_formset = QualificationInlineFormSet(instance=applicant)
employment_formset = EmploymentInlineFormSet(instance=applicant)
c = {
'job' : job,
'form' : form ,
'bottom_form' : bottom_form,
'education_formset' : education_formset,
'qualification_formset' : qualification_formset,
'employment_formset' : employment_formset,
}
return render(request, 'jobs/application.html', c)
为了自定义表单集,我定义了以下内容:
class BaseFormSet(BaseModelFormSet):
def __init__(self, *args, **kwargs):
super(BaseFormSet, self).__init__(*args, **kwargs)
for form in self.forms:
form.empty_permitted = False
使用方法如下:
EducationInlineFormSet = inlineformset_factory(Applicant, Education, extra=1, can_delete=False, formset=BaseFormSet)
这将返回上面的错误,并且在阅读了大量内容之后,我仍然不知道如何继续将实例传递给formset。
任何帮助都将不胜感激。
当做,
克里斯。
最佳答案
我有一个类似的问题-问题是定制的表单集。
尝试从BaseInlineFormSet
(不是BaseModelFormSet
)进行子类化。
这里是the docs的相关部分。
