python - 如何添加 标签而不是

Question

表单.py

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

def __init__(self, type_id, *args, **kwargs):
    super(TypeSelectionForm, self).__init__(*args, **kwargs)

    _type_checkbox = self.fields['checkbox_field']       
    MY_CHOICES=((type.id, type.title) for type in type)
    _type_checkbox.choices = MY_CHOICES
    initial_val = []
    type_selection = Types.objects.filter(parent_type_id=type_id,is_active=True)
    for type_selection in type_selection:
        initial_val.append(type_selection.id)
    _type_checkbox.initial = initial_val

View .py

def types(method):
    """"""""""""
    types = TypeSelectionForm(type_id)
    return render(request,'types.html',{'types':types})

在模板中，我像这样渲染字段，

类型.html

    {% for field in types.checkbox_field %}                                 
     <div class="deletelist">
     {{field}}<br />
    </div>
   {% endfor %}

它正在生成这样的 html，

<ul>
<li><label for="id_checkbox_field_0"><input checked="checked" type="checkbox" name="checkbox_field" value="597" id="id_checkbox_field_0" /> comp lab</label></li>
<li><label for="id_checkbox_field_1"><input checked="checked" type="checkbox" name="checkbox_field" value="598" id="id_checkbox_field_1" /> phy lab</label></li>
<li><label for="id_checkbox_field_2"><input checked="checked" type="checkbox" name="checkbox_field" value="599" id="id_checkbox_field_2" /> chem lab</label></li>
</ul>

我想替换 <ul>和 <li>用 <div class="class-name"> 标记

需要帮助。

为什么不使用 Django 模板标签的强大功能？

from django import template
from django.utils.safestring import mark_safe
register = template.Library()


@register.filter("as_div")
def as_div(form):
    form_as_div = form.as_ul().replace("<ul", "<div").replace("</ul", "</div")
    form_as_div = form_as_div.replace("<li", "<div").replace("</li", "</div")
    return mark_safe(form_as_div)

将其放入模板标签中，然后在您的模板中简单地执行此操作

{% load ad_div %}

{# some Code #}

{{ form|as_div }}

{# some other code #} 

============================

另一种方法是扩展 django 表单模型

如下

from django.forms.forms import BaseForm

Class AsDiv(BaseForm):

def as_div(self):
        return self._html_output(
            normal_row = u'<div%(html_class_attr)s>%(errors)s%(label)s %(field)s%(help_text)s</div>',
            error_row = u'<div>%s</div>',
            row_ender = '</div>',
            help_text_html = u' <span class="helptext">%s</span>',
            errors_on_separate_row = False)

然后你就可以这样做是你的模板

{{ form.as_div }}
