我已经创建了一个自定义小部件OrderedCheckboxSelectMultiple
,我只是将<ul>
替换为<ol>
,并向<label>
,<li>
等添加一些类:
class OrderedCheckboxSelectMultiple(forms.CheckboxSelectMultiple):
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'<ol class="numeric">']
# Normalize to strings
str_values = set([force_unicode(v) for v in value])
for i, (option_value, option_label) in enumerate(chain(self.choices, choices)):
# If an ID attribute was given, add a numeric index as a suffix,
# so that the checkboxes don't all have the same ID attribute.
if has_id:
final_attrs = dict(final_attrs, id='%s_%s' % (attrs['id'], i))
label_for = u' for="%s"' % final_attrs['id']
else:
label_for = ''
cb = forms.CheckboxInput(final_attrs, check_test=lambda value: value in str_values)
option_value = force_unicode(option_value)
rendered_cb = cb.render(name, option_value)
option_label = conditional_escape(force_unicode(option_label))
output.append(u'<li class="liAll"><label%s class="checkbox inline">%s <span class="spanLabel">%s</span></label></li>' % (
label_for, rendered_cb, option_label))
output.append(u'</ol>')
return mark_safe(u'\n'.join(output))
我在表单的两个不同字段中使用此小部件:
^{pr2}$问题是,当我第一次提交表单时,会出现验证错误:
Select a valid choice. is not one of the available choices.
然后,当我再次勾选选项时,它会毫无困难地验证。我在这里迷路了。有什么建议吗?在
注意:
如果我使用forms.CheckboxSelectMultiple
作为alert1
和alert2
的小部件,也会发生同样的情况。在
编辑:
调试时,我可以看到第一次提交时alert1
和{
对不起,我弄错了。alert1
和{request.POST
上,但它们都是{
编辑2:
使用Chrome的“Inspect element”我可以看到表单第一次正确呈现:
<ol class="numeric">
<li class="liAll">
<label for="id_alert1_0" class="checkbox inline">
<div class="checker" id="uniform-id_alert1_0">
<span>
<input value="1" type="checkbox" class="check" name="alert1" id="id_alert1_0" style="opacity: 0;">
</span>
</div>
</label>
</li>
<li class="liAll">
<label for="id_alert1_1" class="checkbox inline">
<div class="checker" id="uniform-id_alert1_1">
<span>
<input id="id_alert1_1" type="checkbox" class="check" value="2" name="alert1" style="opacity: 0;">
</span>
</div>
</label>
</li>
</ol>
然后再次显示验证消息,但呈现的表单看起来相同:
<ol class="numeric">
<li class="liAll">
<label for="id_alert1_0" class="checkbox inline">
<div class="checker" id="uniform-id_alert1_0">
<span>
<input value="1" type="checkbox" class="check" name="alert1" id="id_alert1_0" style="opacity: 0;">
</span>
</div>
</label>
</li>
<li class="liAll">
<label for="id_alert1_1" class="checkbox inline">
<div class="checker" id="uniform-id_alert1_1">
<span>
<input id="id_alert1_1" type="checkbox" class="check" value="2" name="alert1" style="opacity: 0;">
</span>
</div>
</label>
</li>
</ol>
我用提交按钮提交帖子:
<button type="submit" class="btn btn-primary">Send</button>
我复制并粘贴了你的代码在一个快速的django应用程序中。对我来说很好。是否还有其他地方会出错?OSX上的Django1.4
