Django：如何在表单标签中包含 url 链接

发布于 2024-11-17 02:12:09 字数 771 浏览 1 评论 0原文

我的用例看起来非常基本，但我在网上找不到任何东西！

这个想法是一个带有复选框“我已阅读并同意条款和条件”的表格还有一个“条款和条件”链接，指向包含此类条款和条件的页面...... 经典的！

所以我的表单中有一个字段如下：

tos = forms.BooleanField(widget=forms.CheckboxInput(),
                         label=_(u'I have read and agree to the <a href="%s" target="_blank">terms and conditions</a>' % reverse('terms_of_use')),
                         initial=False)

其中“使用条款”是 urls.py 中我的 url 模式之一的名称

但是我收到错误：

ImproperlyConfigured: The included urlconf urls doesn't have any patterns in it

我的 urlconf 在整个网站上运行良好，所以我认为问题是渲染表单时 urlconf 是否尚未填充？

我尝试使用lazy_reverse=lazy(reverse,str)而不是reverse，但它没有解决任何问题。

有办法让这个工作吗？该用例看起来非常非常基本，所以肯定有一种方法可以做到这一点，而不必分解我的模板内的表单？！

My use case looks very basic but I couldn't find anything on the web!

The idea is a form with checkbox "I have read and agree to the terms and conditions"
And a link on "terms and conditions" which points to a page with such terms and conditions...
Classic!

So I have a field in my form as follows:

tos = forms.BooleanField(widget=forms.CheckboxInput(),
                         label=_(u'I have read and agree to the <a href="%s" target="_blank">terms and conditions</a>' % reverse('terms_of_use')),
                         initial=False)

where 'terms of use' is the name of one of my url patterns in urls.py

But I get an error:

ImproperlyConfigured: The included urlconf urls doesn't have any patterns in it

My urlconf works fine on the whole site so I supposed that the problem was that the urlconf is not yet populated when the form is rendered ?

I tried using lazy_reverse = lazy(reverse, str) instead of reverse, but it doesn't solve anything.

Is there a way to make this work ? The use case seems very very basic so there surely is a way to do it without having to break up the form inside my template ?!

我使用这个语法

from django.urls import reverse
from django.utils.functional import lazy

privacy = forms.BooleanField(label = lazy(lambda: _("Privacy <a href='%s' a>policy</a>" % reverse('privacy'))))

I use this syntax

from django.urls import reverse
from django.utils.functional import lazy

privacy = forms.BooleanField(label = lazy(lambda: _("Privacy <a href='%s' a>policy</a>" % reverse('privacy'))))

lazy_reverse 不起作用，因为您在使用 "...%s..." % lazy(blah) 表示法后第二秒就转身并解除了它的惰性。

我想你可以尝试偷懒整个事情，即

label = lazy(lambda: _("bla %s bla" % reverse('something')))

但我没有测试这个

，只是覆盖 __init__ 处的标签，即

self.fields['myfield'].label = 'blah %s bla' % reverse('bla')

lazy_reverse won't work since you're turning around and unlazying it the second after with your "...%s..." % lazy(blah) notation.

I suppose you could try to lazy the whole thing, i.e.

label = lazy(lambda: _("bla %s bla" % reverse('something')))

but I did not test this

alternatively, just override the label at __init__, i.e.

self.fields['myfield'].label = 'blah %s bla' % reverse('bla')

您可以提供一个链接，如下所示的表单标签：

foo_filter=forms.ModelChoiceField(FooFilter.objects.all(),
               label=format_html('<a href="{}">{}</a>', reverse_lazy('foo-filter'), 
                                 FooFilter._meta.verbose_name))

请参阅AppRegistryNotReady：lazy format_html ()？

You can provide a link a form label like this:

foo_filter=forms.ModelChoiceField(FooFilter.objects.all(),
               label=format_html('<a href="{}">{}</a>', reverse_lazy('foo-filter'), 
                                 FooFilter._meta.verbose_name))
