本文介绍了基于Django类的视图中的URL参数和逻辑(TemplateView)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我不清楚在Django 1.5中如何在基于类的视图中访问URL参数是最好的。



请考虑以下内容:



查看:

  from django.views.generic.base import TemplateView 


class Yearly(TemplateView):
template_name =calendars / yearly.html

current_year = datetime.datetime.now()。year
current_month = datetime.datetime.now()。month

def get_context_data(self,** kwargs):
context = super(Yearly,self).get_context_data(** kwargs)
context ['current_year'] = self.current_year
context [' current_month'] = self.current_month
返回上下文

URLCONF:

  from .views import Yearly 


urlpatterns = patterns('',
url(
regex = r'^(?P< year> \d +)/ $',
view = Yearly.as_view(),
name ='yearly-view '
),

我想访问我的视图中的年份参数,所以我可以做如下逻辑:

 code> month_names = [1月,二月,三月,四月,五月,六月,七月,
八月,九月 ,十一月,十二月]

为月,月名为枚举(month_names,start = 1):
is_current = False
如果year == current_year和month == current_month:
is_current = True
months.append({
'month':month,
'name':month_name,
'is_current':is_current} )

如何最好访问CBV中的url参数,像上面那样的 TemplateView ,应该在哪里理想地放置这样的逻辑,例如。在方法中?

解决方案

要在基于类的视图中访问url参数,请使用 self.args self.kwargs 所以你可以通过执行 self.kwargs ['year']


It is unclear to me how it is best to access URL-parameters in class-based-views in Django 1.5.

Consider the following:

View:

from django.views.generic.base import TemplateView


class Yearly(TemplateView):
    template_name = "calendars/yearly.html"

    current_year = datetime.datetime.now().year
    current_month = datetime.datetime.now().month

    def get_context_data(self, **kwargs):
        context = super(Yearly, self).get_context_data(**kwargs)
        context['current_year'] = self.current_year
        context['current_month'] = self.current_month
        return context

URLCONF:

from .views import Yearly


urlpatterns = patterns('',
    url(
        regex=r'^(?P<year>\d+)/$',
        view=Yearly.as_view(),
        name='yearly-view'
    ),
)

I want to access the year parameter in my view, so I can do logic like:

month_names = ["January", "February", "March", "April", "May", "June", "July",
               "August", "September", "October", "November", "December"]

     for month, month_name in enumerate(month_names, start=1):
        is_current = False
        if year == current_year and month == current_month:
            is_current = True
        months.append({
            'month': month,
            'name': month_name,
            'is_current': is_current})

How would one best access the url parameter in CBVs like the above that is subclassed of TemplateView and where should one ideally place the logic like this, eg. in a method?

解决方案

To access the url parameters in class based views, use self.args or self.kwargs so you would access it by doing self.kwargs['year']
