在 Django 中使用一个创建视图的多个表单

Question

我有 5 个表格：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，因为它只接受一种形式 class。如何为多个表单创建单一视图？

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'

我希望在一个请求和一个按钮中提交所有表单。它们与外键相互关联 EducationForm、ExperienceForm、RecommendationForm、OtherDocumentsForm 使用外键

连接到 MyForm

Answer 1

由于 MyForm 将与其他表单同时提交，因此您需要从所有其他模型中排除 UserForm_uz 的 ForeignKey 字段，相关对象尚不存在，因此你不能 select 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

这是一个使用三种形式的示例视图（我漏掉了两种以节省输入）。给每个表单一个前缀，这样可以降低表单字段名称冲突的风险。一次验证它们，如果任何形式无效，则视图不应继续。先保存 MyForm 并使用输出作为外键值传递给其他窗体

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，您需要以相同的表单标记呈现所有表单

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