python之Django之简单的搜索表单

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。

请您参考如下方法:

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')
