Question

widgets.py

from django.utils.safestring import mark_safe
from django.forms.widgets import Widget, Select
from django import forms
from django.conf import settings


class CheckboxDivSelectMultiple(CheckboxSelectMultiple):
'''renders the checkboxes as divs with a hard coded class'''

def render(self, name, value, attrs=None, choices=()):
    if value is None: value = []
    has_id = attrs and 'id' in attrs
    final_attrs = self.build_attrs(attrs, name=name)
    output = [u'<div>']
    """""""""
        option_label = conditional_escape(force_unicode(option_label))
        output.append(u'<div class="%s"><label%s>%s %s</label></div>' % ('new-class', label_for, rendered_cb, option_label))
    output.append(u'</div>')
    return mark_safe(u'\n'.join(output))

forms.py

class TypeSelectionForm(forms.Form):
    checkbox_field = forms.MultipleChoiceField(widget=forms.CheckboxDivSelectMultiple(), label="", required=False)

我正在使用自定义小部件覆盖checkboxselectmultiple。我将小部件代码放在widgets.py中。返回错误“ViewDoesNotExist at / setting / type /”

Exception Type: ViewDoesNotExist at /setting/type/
Exception Value: Could not import setting.views.types. View does not exist in module setting.views.

Answer 1

根据您的导入，不应该这一行：

class CheckboxDivSelectMultiple(CheckboxSelectMultiple):

是吗？

class CheckboxDivSelectMultiple(forms.CheckboxSelectMultiple):

无法导入setting.views.types。模块setting.views中不存在视图
