python - Django - 简单的搜索表单

Question

使用 Django 1.9 和 Python 3.5，我想制作一个简单的搜索表单:

views.py

from django.views import generic
from django.shortcuts import render
from .models import Movie, Genre

class IndexView(generic.ListView):
    template_name = 'movies/index.html'
    page_template = 'movies/all_movies.html'
    context_object_name = 'all_movies'
    model = Movie

    def get_context_data(self, **kwargs):
        context = super(IndexView, self).get_context_data(**kwargs)
        context.update({
            'all_genres': Genre.objects.all(),
            'page_title': 'Latest'
        })
        return context

    def get_queryset(self):
        query = request.GET.get('q')
        if query:
            return Movie.objects.filter(title__icontains=query)
        else:
            return Movie.objects.all()

表单

<form method="GET" action="" id="searchform">
    <input class="searchfield" id="searchbox" name="q" type="text" value="{{ request.GET.q }}" placeholder="Search..."/>
</form>

出于某种原因，我不断收到错误消息:

name 'request' is not defined

我不太确定我做错了什么，任何帮助将不胜感激。

Answer 1

该错误并非如您所想的那样来自您的模板。它来自你的观点

def get_queryset(self):
    query = request.GET.get('q')

应该是

    query = self.request.GET.get('q')
