当我在网络表单中进行搜索时，似乎找到了匹配项，但未显示：
我该怎么做才能使 SERP 显示？我的代码是：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<link rel="stylesheet" type="text/css" href="/static/css/main.css"/>
<title>Search Demonstration App</title>
</head>
<body>
<form action="/sign" method="post">
<div>Search Demo</div>
<div><textarea name="search" rows="1" cols="60"></textarea></div>
<div><input type="submit" value="Search"/></div>
<div><textarea name="content" rows="3" cols="60"></textarea></div>
<div><input type="submit" value="Comment"/></div>
</form>
{{number_returned}} of {{results.number_found}} comments found <p>
{% for scored_document in results %}
{% for field in scored_document.fields %}
{{field.value}}
{% endfor %}
<p>
{% endfor %}
<a href="{{ url }}">{{ url_linktext }}</a>
</body>
</html>
和.py
class SearchAPI(webapp.RequestHandler):
"""Handles search requests for comments."""
def get(self):
"""Handles a get request with a query."""
uri = urlparse(self.request.uri)
query = ''
if uri.query:
query = parse_qs(uri.query)
query = query['query'][0]
# sort results by author descending
expr_list = [search.SortExpression(
expression='author', default_value='',
direction=search.SortExpression.DESCENDING)]
# construct the sort options
sort_opts = search.SortOptions(
expressions=expr_list)
query_options = search.QueryOptions(
limit=3,
sort_options=sort_opts)
query_obj = search.Query(query_string=query, options=query_options)
results = search.Index(name='ad').search(query=query_obj)
#logging.info("number of results:" +len(results))
if users.get_current_user():
url = users.create_logout_url(self.request.uri)
url_linktext = 'Logout'
else:
url = users.create_login_url(self.request.uri)
url_linktext = 'Login'
template_values = {
'results': results,
'number_returned': len(results.results),
'url': url,
'url_linktext': url_linktext,
}
path = os.path.join(os.path.dirname(__file__), 'searchapi.html')
self.response.out.write(template.render(path, template_values))
索引是这样构建的：
class CreateAdHandler(BaseHandler):
def post(self):
ad = Ad.get_by_id(self.session.get('ad_id'))
city_entity = montaomodel.City.all().filter('name =', ad.city).get()
region_entity = montaomodel.Region.all().filter('name =', ad.region).get()
form = PreviewAdForm(self.request.params)
if form.validate():
ad.set_password(self.request.get('password'))
ad.published = True
ad.put()
doc = search.Document(doc_id=str(ad.key()),
fields=[search.TextField(name='title',
value=ad.title),search.TextField(name='text',
value=ad.text),search.TextField(name='city',
value=ad.city),search.TextField(name='region',
value=ad.region),search.NumberField(name='cityID',
value=city_entity.key().id()),search.NumberField(name='regionID',
value=region_entity.key().id()),search.NumberField(name='category',
value=int(ad.category)), search.NumberField(name='constant',
value=1), search.NumberField(name='adID',
value=ad.key().id()),
search.TextField(name='name',
value=ad.name
)],
language='en')
search.Index(name='ad').add(doc) # should this be "put" instead? see https://developers.google.com/appengine/docs/python/search/overview#Deleting_Documents
self.redirect('/vi/%d.html' % (ad.key().id(), ))
else:
logging.info('form did not validate')
self.render_jinja('preview', form=form, ad=ad)
更新
通过仔细调试，表明该行不起作用：{% for f in scored_document.fields %}. 我通过调试找到了，但我不知道为什么。所以至少我现在更接近解决方案，但还没有完成。
更新 2
我不明白为什么不访问这些字段。我可以添加数据并将其输出到控制台：
INFO 2013-05-14 01:00:53,944 main.py:4437] result: search.ScoredDocument(doc_id=u'eb24f746-c60a-462c-9f64-a06ad6a823cb', fields=[search.TextField(name=u'author', value=u'test'), search.TextField(name=u'comment', value=u'test'), search.DateField(name=u'date', value=datetime.datetime(2013, 5, 13, 0, 0))], language=u'en', rank=74648319L)
INFO 2013-05-14 01:00:53,944 main.py:4437] result: search.ScoredDocument(doc_id=u'af0de892-0e59-4c12-bd9e-6e8caa2067d4', fields=[search.TextField(name=u'author', value=u'test'), search.TextField(name=u'comment', value=u'test'), search.DateField(name=u'date', value=datetime.datetime(2013, 5, 14, 0, 0))], language=u'en', rank=74653247L)
此日志记录现在是这样进行的：
for r in results:
logging.info("result: " + str(r))
因此，如果我可以将这样的数据记录到控制台，为什么我不能将其输出到我的页面？
