django

Question

我希望能够轻松地在我的网站上创建搜索页面，仅搜索标题。 这样做最简单的方法是什么？

我是django的新手，我不知道如何更好地做到这一点， 我已阅读手册，但令人困惑。

到目前为止，这是我的代码：

import re
from django.db.models import Q
def normalize_query(query_string,
                    findterms=re.compile(r'"([^"]+)"|(\S+)').findall,
                    normspace=re.compile(r'\s{2,}').sub):
    ''' Splits the query string in invidual keywords, getting rid of unecessary spaces
        and grouping quoted words together.
        Example:

        >>> normalize_query('  some random  words "with   quotes  " and   spaces')
        ['some', 'random', 'words', 'with quotes', 'and', 'spaces']

    '''
    return [normspace(' ', (t[0] or t[1]).strip()) for t in findterms(query_string)] 

def get_query(query_string, search_fields):
    ''' Returns a query, that is a combination of Q objects. That combination
        aims to search keywords within a model by testing the given search fields.

    '''
    query = None # Query to search for every search term        
    terms = normalize_query(query_string)
    for term in terms:
        or_query = None # Query to search for a given term in each field
        for field_name in search_fields:
            q = Q(**{"%s__icontains" % field_name: term})
            if or_query is None:
                or_query = q
            else:
                or_query = or_query | q
        if query is None:
            query = or_query
        else:
            query = query & or_query
    return query

views.py

def search(request):
    query_string = ''
    found_entries = None
    if ('q' in request.GET) and request.GET['q'].strip():
        query_string = request.GET['q']

        entry_query = get_query(query_string, ['title', 'body',])

        found_entries = Entry.objects.filter(entry_query).order_by('-pub_date')

    return render_to_response('search/search_results.html',
                          { 'query_string': query_string, 'found_entries': found_entries },
                          context_instance=RequestContext(request))

首先在pycharm中显示我在这个＆＃39; RequestContext＆＃39;下面的红线。 如果我运行这个我得到一个错误

Page not found (404)
