Django在每个页面上添加反馈表单

我有一个用户反馈的表单视图:

url.py:

url(
    r'^feedback/$',
    'tool.views.Feedback',
    name='feedback'
),
url(
    r'^thanks/$',
    direct_to_template, {
        'template': 'tool_feedback_thanks.html'
    },
    name='feedback_thanks'
),

forms.py:

class FeedbackForm(forms.Form):
    yes_no = forms.ChoiceField(
        choices=YES_NO_CHOICE,
        initial=1,
        widget=forms.RadioSelect(attrs={'class': 'can_reveal_input'}),
        label="Are you happy with Our service?"
    )
    comments = forms.CharField(
        widget=forms.Textarea(attrs={
            'class': 'hidden', 'placeholder': 'Leave us your comments...'
        }),
        required=False,
        label=""
    )

views.py:

def Feedback(request,
                 template_name='tool_feedback.html'):
    title = u'Leave us some feedback'
    form = FeedbackForm(request.POST or None)
    if form.is_valid():
        yes_no = form.cleaned_data['yes_no']
        comments = form.cleaned_data['comments']
        sender = "A Unirac website user"
        recipients = ['[email protected]']
        send_mail(yes_no, comments, sender, recipients)
        return HttpResponseRedirect(
            reverse('feedback_thanks')
        )
    return render_to_response(template_name, {
        'title': title,
        'form': form,
    }, RequestContext(request))

这是一种享受,但现在客户要求将此表单包含在每一页上。我猜表单可以通过JS提交到适当的URL,但是在每个页面上包含未绑定表单的最佳方法是什么?

我会创建一个上下文处理器,将表单包含在每个视图中。

编辑:

要让用户访问他/她浏览的前一个URL,您可以只使用URL。

# yourapp/context_processors.py
def feedback_form_context_processor(request):
    return {
        'feedback_form': FeedbackForm(),
        'feedback_form_url': reverse("feed_app:form_process", args=(request.path))
    }

这就是urls.py的样子:

urlpatterns = patterns('feed_app.views',
    url(r'^process-feedback-form/(?P<next_url>\d+)', 'form_process', name='form_process'),
)

以及窗体的视图:

def form_process(request, next_url):
    # Process form, do your stuff here
    # if its valid redirect to the url
    return redirect(next_url)

你应该构造你的模板以获得正确的布局。例如,有一个基本模板:

# templates/base.html
<html>
<body>
..
{% block maincontent %}
{% endblock %}
..
{# The form!!! #}
<form action='{{feedback_form_url}}' method='POST'>
@csrftoken
{{ feedback_form.as_p }}
</form>

</body>
</html>

要创建一个简单的视图,只需使用正确的模板。

# templates/just_a_random_view.html

{% extends base.html %}

{% block maincontent %}
<h1>Content!</h1>
{% endblock %}

最后,将其包含在您的设置中:

# settings.py
TEMPLATE_CONTEXT_PROCESSORS = (
    "django.contrib.auth.context_processors.auth",
    ...
    "yourapp.context_processors.feedback_form_context_processor"
)

我相信包含form的最简单方法是使用assignment_tag:
在模板库中:

@register.assignment_tag
def feedback_form(format_string):
    return FeedbackForm()

以模板

{% feedback_form as form %}
{# display form... %}
{{ form.as_p }}

加上@bmihelac,谁的回答对我来说真的很好。由于django 2.0 assignment_tag被弃用,转而支持simple_tag。所以你可以完全按照他的答案,用simple_tag替换assignment_tag,像这样:

from django import template

from .forms import FeedbackForm

register = template.Library()

@register.simple_tag
def feedback_form():
    return FeedbackForm()

然后只需参考https://docs.djangoproject.com/en/2.1/howto/custom-template-tags/#code-layout了解如何将其导入到模板中!
