我想将 Django inlineformset_factory 与自定义表单集一起使用，并希望使用 django-dynamic-formset 添加或删除该内联表单集.
表格:
class CreatePacketForm(forms.ModelForm):
"""
CreatePacketForm class
"""
class Meta:
model = Packet
exclude = ('customer', 'created_on', 'updated_on',
'created_by', 'updated_by', 'remark', 'p_id'
)
ItemFormSet = inlineformset_factory(Packet, Item, form=CreatePacketForm,
formset=CreateItemForm,
extra=1, max_num=20, can_delete=False)
查看:
class CreatePacketView(LoginRequiredMixin, CreateView):
"""
"""
model = Packet
form_class = CreatePacketForm
template_name = CREATE_PACKET_TEMPLATE
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)
item_form = ItemFormSet()
return self.render_to_response(self.get_context_data(form=form,
item_form=item_form,))
模板:
{% load static %}
<!DOCTYPE html>
<html>
<head>
<title>Popup</title>
</head>
<body>
<div style="border: 1px solid;padding: 10px;">
<br>
<div align="middle">
<span style="font-size: x-large;">Please Enter Item Details</span>
</div>
<br>
<form id="packet_form" method="post" action="" style="margin: 0 20% 0 20%;padding: 10px;">
{% csrf_token %}
{{ form.non_field_errors }}
{{ form }}
{{ item_form.management_form }}
{{ item_form.non_form_errors }}
{% for subform in item_form %}
<div class="inline {{ item_form.prefix }}">
{{ subform }}
</div>
{% endfor %}
<div align="middle">
<button type="submit">Submit</button>
<button type="reset">Reset</button>
</div>
</form>
</div>
<script type="text/javascript" src="{% static 'girvi/js/jquery-1.3.2.min.js' %}"></script>
<script type="text/javascript" src="{% static 'girvi/js/jquery.formset.js' %}"></script>
<script type="text/javascript" src="{% static 'girvi/js/RelatedObjectLookups.js' %}"></script>
<script type="text/javascript" src="{% static 'girvi/js/swfobject.js' %}"></script>
<script type="text/javascript">
$(".inline.{{ item_form.prefix }}").formset({
prefix: "{{ item_form.prefix }}"
});
</script>
</body>
</html>
我的内联表单集在没有自定义表单集的情况下工作正常。但是当我在模板中渲染它时，它没有 management_form 并且我的表单集中的所有字段都可以被删除。
没有自定义表单集的渲染模板
<!DOCTYPE html>
<html>
<head></head>
<body>
<div style="border: 1px solid;padding: 10px;">
<br></br>
<div align="center"></div>
<br></br>
<form id="packet_form" style="margin: 0 20% 0 20%;padding: 10px;" action="" method="post">
<input type="hidden" value="u3H6thNcyymuwQDrLf5Spnr6E6DEYTxA" name="csrfmiddlewaretoken"></input>
<input id="id_item_set-TOTAL_FORMS" type="hidden" value="1" name="item_set-TOTAL_FORMS"></input>

以及带有自定义表单集的模板
<!DOCTYPE html>
<html>
<head></head>
<body>
<div style="border: 1px solid;padding: 10px;">
<br></br>
<div align="center"></div>

<div class="inline None dynamic-form"></div>
<a class="add-row" href="javascript:void(0)"></a>

</form>
</div>

最佳答案
您的问题
ItemFormSet = inlineformset_factory(Packet, Item, form=CreatePacketForm,
formset=CreateItemForm,
extra=1, max_num=20, can_delete=False)
form kwarg 这里是自定义formset表单
所以应该是:
ItemFormSet = inlineformset_factory(Packet, Item, form=CreateItemForm, extra=1, max_num=20, can_delete=False)
