Forms.py

from django import forms
from apps.tcg.models import TestcaseCache
from apps.tcg.models import Keyword
from django.core.exceptions import ValidationError
from django.forms import ModelForm

# Create the form class.


class TestcaseCacheForm(forms.ModelForm),KeywordForm(models.ModelForm):

    class Meta:
        model = TestcaseCache,Keyword
        fields = ('name','package_name','summary','pre_requisite','steps','expected_results','post_test','data_provider','author','reviewer','release',keyname,'bugs','notes','project','feature')

views.py

from forms import TestcaseCacheForm

    def createForm(request):
        return render(request,'tcgform.html',{'form':TestcaseCacheForm(),'testcase_object_array':testcase_object_array,'author_name':author_name,'project_name':project_id,'feature_name':feature_name})

ModelForms不允许您继承多个模型类，但是，视图对它可以处理的表单类的数量无关紧要。对于最终用户，您可以在一个HTML表单中提供两个表单类。例如，假设您有两个模型表单类：

def my_view(request):
    keyword_form = KeywordForm(request.POST or None)
    another_form = AnotherForm(request.POST or None)

    if keyword_form.is_valid and another_form.is_valid():
        # do whatever

    return render(request, 'your-template.html',
        {'keyword_form': keyword_form, 'another_form': another_form})


# your_template.html
<form action="." method="post" enctype="application/x-www-form-urlencoded">
    <ul>
        {{ keyword_form.as_ul }}
        {{ another_form.as_ul }}
    </ul>
    <button type="submit">Submit</button>
</form>

当然，如果您需要严格控制哪些字段放在哪里，您始终可以定义字段位置，而不是使用快速和脏的渲染。希望能帮到你。
