表单集隐藏字段的初始值

Question

我对在表单集中部署的modelform中隐藏字段的初始值有问题。只有第一个表单的初始值在隐藏字段中，其他表单为空。在

模型格式为：

class md_changelogFormModel(forms.ModelForm):
    post_docs = forms.CharField(widget=forms.HiddenInput(),
                                initial="READY_FOR_RUN")
    # Other fields

    class Meta:
        model = md_changelog
        fields = '__all__'

在基于BaseInlineFormSet的表单中使用相同的模型md_changelog：

^{pr2}$

使用inlineformset_factory创建formset类：

md_changelogFormSet = inlineformset_factory(md_orderlog, md_changelog,
                                            form=md_changelogFormModel,
                                            formset=md_changelogForm,
                                            extra=1, max_num=20)

formset类在基于类的视图中实例化：

def get(self, request, *args, **kwargs):
    """
    Handles GET requests and instantiates blank versions of the form
    and its inline formsets.
    """
    self.object = None
    form_class = self.get_form_class()
    form = self.get_form(form_class)

    md_changelog_form = md_changelogFormSet(initial=[{'post_docs':'READY_FOR_RUN'}])

    return self.render_to_response(
        self.get_context_data(form=form,
                              md_changelog_form=md_changelog_form))

问题是当post函数接收到请求.POST，只有表单集数据的第一个表单中的post_docs hidden字段填充初始值，其他字段没有

如何初始化其他窗体？在

如果需要为给定表单域中的所有表单提供初始值，请查看文档：https://docs.djangoproject.com/en/1.8/topics/forms/formsets/#using-initial-data-with-a-formset

因此，在我看来，为了用相同的初始日期初始化所有3个字段，您应该将代码更改为：

def get(self, request, *args, **kwargs):
    """
    Handles GET requests and instantiates blank versions of the form
    and its inline formsets.
    """
    self.object = None
    form_class = self.get_form_class()
    form = self.get_form(form_class)

   md_changelog_form = md_changelogFormSet(initial=[
       {'post_docs':'READY_FOR_RUN'},
       {'post_docs':'READY_FOR_RUN'},
       {'post_docs':'READY_FOR_RUN'},
   ])

   return self.render_to_response(self.get_context_data(form=form, md_changelog_form=md_changelog_form))

希望有帮助！在
