我有一个django UpdateView，它需要继承三个不同的模型和不同的模型。CreateView可以很好地处理三种不同的模型形式。
models.py:
class Employee(models.Model):
"""
Create employee attributes
"""
employee_user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True)
e_id = models.IntegerField(unique=True, null=True, blank=True)
first_name = models.CharField(max_length=128,blank=True)
last_name = models.CharField(max_length=128, blank=True)
.....
class WorkExperience(models.Model):
"""
Stores employee previous work experiences
"""
employee = models.ForeignKey('Employee', related_name='we_employee', on_delete=models.CASCADE, null=True)
previous_company_name = models.CharField(max_length=128, null=True)
job_designation = models.CharField(max_length=128, null=True)
from_date = models.DateField(null=True)
......
class Education(models.Model):
"""
Stores employee education background
"""
employee = models.ForeignKey('Employee', related_name='edu_employee', on_delete=models.CASCADE, null=True)
institution_name = models.CharField(max_length=128, null=True)
degree = models.CharField(max_length=128, null=True)
.....
views.py:
class EmployeeUpdateView(LoginRequiredMixin,UpdateView):
"""
Update a created a employee
"""
login_url = '/authentication/login/'
template_name = 'employee/employee_add_form.html'
form_class = EmployeeAddModelForm
work_form_class = WorkExperienceForm
education_form_class = EducationForm
queryset = Employee.objects.all()
def form_valid(self, form):
print(form.cleaned_data)
return super().form_valid(form)
def get_object(self):
id_ = self.kwargs.get("id")
return get_object_or_404(Employee, id=id_)
当我进入"更新"视图时，我只能更新EmployeeAddModelForm值。但其他表单(WorkExperienceForm、EducationForm(的字段不会出现，更不用说编辑字段的值了。我想我的观点是不对的。我需要建议来更正我的更新视图。
如果您想在一个HTML文件中放入多个表单，请按照我的方式编写。
class EmployeeUpdateView(LoginRequiredMixin,UpdateView):
login_url = '/authentication/login/'
def form_valid(self, form):
print(form.cleaned_data)
return super().form_valid(form)
def get(self, request, *args, **kwargs):
id_ = self.kwargs.get("id")
user = Employee.objects.get(id=id_)
work = WorkExperience.objects.get(employee=user)
education = Education.objects.get(employee=user)
return render(request, self.template_name, {
'form': EmployeeAddModelForm(instance=user),
'work_form': WorkExperienceForm(instance=work),
'education_form': EducationForm(instance=education)
}
)
def post(self, request):
first_name = request.POST['first_name']
# Your own code...
.....
我认为每种形式的论点都取决于形式的定义
用一种非常简单的方式，HTML文件看起来像这样：
<body>
<form method="post">
{% csrf_token %}
{{ employ_form }}
{{ work_form }}
{{ edu_form }}
<button type="submit">OK</button>
</form?
</body>
</html>
我不确定这是否是最好的选择。
将表单放入get_context_data中如何？类似于context['form1']=EmployeeAddModelForm((context['form2]=工作体验表单((等编辑：
def get_context_data(self, **kwargs):
context = super(EmployeeUpdateView, self).get_context_data(**kwargs)
context['form'] = EmployeeAddModelForm()
context['form2'] = WorkExperienceForm()
context['form3'] = EducationForm()
return context
