如何干燥我的 Django 视图

Question

随着我的 Django 技能水平的提高，我开始以不同的方式看待我的代码，并且迫切希望找到一种方法来避免在我的观点中重复自己 - 如下所示。将不胜感激如何设置我的视图的示例。谢谢。

# -*- coding: utf-8 -*-
from django.shortcuts import render
from listings.models import Listing
from posts.models import Reveal


def home(request):
    return render(request, "pages/home.html", {})


def about(request):
    reveals = Reveal.objects.all().order_by('?')[:1:1]
    listings = Listing.objects.filter(featured_choices="YES").order_by('?')[:1:1]
    return render(request, 'pages/about.html', {'listings': listings, 'reveals': reveals})


def team(request):
    reveals = Reveal.objects.all().order_by('?')[:1:1]
    listings = Listing.objects.filter(featured_choices="YES").order_by('?')[:1:1]
    return render(request, "pages/theteam.html", {'listings': listings, 'reveals': reveals})


def why(request):
    reveals = Reveal.objects.all().order_by('?')[:1:1]
    listings = Listing.objects.filter(featured_choices="YES").order_by('?')[:1:1]
    return render(request, "pages/why.html", {'listings': listings, 'reveals': reveals})


def services(request):
    reveals = Reveal.objects.all().order_by('?')[:1:1]
    listings = Listing.objects.filter(featured_choices="YES").order_by('?')[:1:1]
    return render(request, "pages/services.html", {'listings': listings, 'reveals': reveals})


def selling_facts(request):
    reveals = Reveal.objects.all().order_by('?')[:1:1]
    listings = Listing.objects.filter(featured_choices="YES").order_by('?')[:1:1]
    return render(request, "pages/selling_facts.html", {'listings': listings, 'reveals': reveals})


def buying_facts(request):
    reveals = Reveal.objects.all().order_by('?')[:1:1]
    listings = Listing.objects.filter(featured_choices="YES").order_by('?')[:1:1]
    return render(request, "pages/buying_facts.html", {'listings': listings, 'reveals': reveals})


def liquor_licenses(request):
    reveals = Reveal.objects.all().order_by('?')[:1:1]
    listings = Listing.objects.filter(featured_choices="YES").order_by('?')[:1:1]
    return render(request, "pages/liquor_licenses.html", {'listings': listings, 'reveals': reveals})


def contact(request):
    return render(request, "pages/contact.html", {})

您可以通过定义一个 url 命名参数来更改您的 url 以反映它的用途。您可以在单个视图中捕获它并根据该参数呈现不同的页面：

# url definition
url(r'^pages/(?P<page>\w+)/$', views.render_pages, name='render-pages')

# your views
from django.http import Http404

def _get_template_by_parameter(page):
    if page == 'about':
        return 'pages/about.html'
    elif page == 'team':
        return 'pages/theteam.html'
    # some more branches here
    return None

def render_pages(request, page):
    reveals = Reveal.objects.all().order_by('?')[:1:1]
    listings = Listing.objects.filter(featured_choices="YES").order_by('?')[:1:1]
    template = _get_template_by_parameter(page)
    if template:
        return render(request, template, {'listings': listings, 'reveals': reveals})
    else:
        raise Http404

您可以访问您的网址，例如：http://test.com/pages/about 或 http://test.com/pages/team。显然你需要更好的措辞，因为我只是快速编写代码。
