Django中的多个表单和一个单独的create视图

Question

我有5个表单：MyForm、EducationForm、ExperienceForm、RecommendationForm、OtherDocumentsForm我想在一个表单模板中显示它们。我不能用CreateView来做，因为它只接受一个表单类。如何为多个窗体创建单个视图？

class MyForm(forms.ModelForm):
class Meta:
model = UserForm_uz
fields = 'all'
class EducationForm(forms.ModelForm):
class Meta:
model = Education_uz
fields = 'all'
class ExperienceForm(forms.ModelForm):
class Meta:
model = Experience_uz
fields = 'all'
class RecommendationForm(forms.ModelForm):
class Meta:
model = Recommendation_uz
fields = 'all'
class OtherDocumentsForm(forms.ModelForm):
class Meta:
model = OtherDocuments
fields = 'all'

我希望所有的表格都能在一个请求和一个按钮中提交。他们与foreignkey相互关联EducationForm、ExperienceForm、RecommendationForm、OtherDocumentsForm与foreignkey 连接到MyForm

由于MyForm将与其他表单同时提交，您需要从所有其他模型中排除UserForm_uz的ForeignKey字段，因此相关对象还不存在，因此无法选择它

class EducationForm(forms.ModelForm):
class Meta:
model = Education_uz
# Repeated for all four forms
exclude = ['form']  # Whatever the ForeignKey to UserForm_uz is named

下面是一个使用其中三个表单的示例视图(为了节省键入，我漏掉了两个(。为每个表单指定一个前缀，这样可以降低表单字段名称冲突的风险。一次性验证所有表单，如果任何表单无效，则视图不应继续。首先保存MyForm，并使用输出作为外键值传递给其他表单

def my_view(request):
if request.method == 'POST':
my_form = MyForm(request.POST, request.FILES, prefix='user')
education_form = EducationForm(request.POST, request.FILES, prefix='education')
experience_form = ExperienceForm(request.POST, request.FILES, prefix='experience')
if all([my_form.is_valid(), education_form.is_valid(), experience_form.is_valid()]):
form = my_form.save()
education = education_form.save(commit=False)
education.form = form
education.save()
experience = experience_form.save(commit=False)
experience.form = form
experience.save()
return redirect('some-view')
else:
my_form = MyForm(prefix='user')
education_form = EducationForm(prefix='education')
experience_form = ExperienceForm(prefix='experience')
return render(request, 'template.html', {'my_form': my_form, 'education_form': education_form, 'experience_form': experience_form})

在您的模板(template.html(中，您需要在同一表单标签中呈现所有表单

<form method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ my_form }}
{{ education_form }}
{{ experience_form }}
<input type="submit" />
</form>
