Question

我有一个表单工厂，它根据从MailChimp API返回的数据动态构建表单。我正在为表单可能使用的每种类型的小部件构建一个测试用例（选择，无线电和复选框）。现在我在字段的str()表示中搜索子字符串，但是，我假设有一种方法可以直接确定类型？

GroupsForm = groups_form_factory()
form = GroupsForm()
for field in form:
    self.assertIn('type="checkbox"', str(field), 
                  "Form field should be represented by a checkbox.")
    # this works, but, isn't there a way to check the field's widget type?

Answer 1

使用type(field.field.widget)

获取代码中窗口小部件的类型

BoundField在django.forms中定义。

Answer 2

>>> from myapp.forms import RestaurantReviewForm
>>> f = RestaurantReviewForm()
>>> from django.forms.widgets import TextInput
>>> for field in f: print type(field.field.widget), isinstance(field.field.widget, TextInput)
... 
<class 'django.forms.widgets.TextInput'> True
<class 'django.forms.widgets.TextInput'> True
<class 'django.forms.widgets.TextInput'> True
<class 'django.forms.widgets.TextInput'> True
<class 'django.forms.widgets.TextInput'> True
<class 'django.forms.widgets.CheckboxInput'> False
<class 'django.forms.widgets.Select'> False
<class 'django.forms.widgets.Textarea'> False
<class 'captcha.fields.CaptchaTextInput'> False
