我从1.10.7更新到1.11.0，并且在查看表单时出现以下错误。我无法理解我的表格有什么问题。其他形式的工作方式相同。我怀疑它可能是与select2或markdownx的互动，但没有迹象表明它们与1.11不兼容。更新到1.11：TypeError build_attrs（）至多需要2个参数（给出3个）
如何进一步调试？

模板：
<form action="/order_book/invoice/create/" method="post">
{% csrf_token %}
<input type='hidden' name='action' value='create'>
<table>

<!-- other entries like the one above… -->
<tr>

的观点：
def create_code(request): # pragma: no cover
context = {}
if request.method == 'POST':
form = MyForm(request.POST)
if form.is_valid():
pass # Clearly for testing…
form = MyForm()
context['form'] = form
return render(request, 'order_book/create_code.html', context)
形式：
class MyForm(forms.ModelForm):
class Meta:
model = MyModel
fields = '__all__'
widgets = {
'manager': Select2Widget(attrs={'style': 'min-width:400px'}),
}
@Alasdair我这样做，如果有帮助。 – Sardathrion
