我正在为Django中的Web应用程序开发搜索工具。
现在我有了这段代码:
在search.py上:
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
在views.py上:
def search(request):
query_string = ''
found_entries = None
search_fields=('cedula','nombre','usuario')
if ('q' in request.GET) and request.GET['q'].strip():
query_string = request.GET['q']
entry_query = get_query(query_string, search_fields)
found_entries = UsuarioFidetel.objects.filter(entry_query).order_by('-id')
return render_to_response('search/buscar.html', { 'query_string': query_string, 'found_entries': found_entries }, context_instance=RequestContext(request))
我的模板,buscar.html:
{% if found_entries %}
<p>You searched for "{{ query_string }}".</p>
<ul>
{% for i in found_entries %}
<li><a href="{{ q.get_absolute_url }}">{{i.cedula}}{{i.nombre}}{{i.usuario}}</a></li>
{% endfor %}
</ul>
{% endif %}
{% if query_string and not found_entries %}
<p>}Este Usuario no Existe.</p>
{% else %}
<p>Busca el usuario por nombre, usuario o cedula y presiona Enter.</p>
{% endif %}
现在,我需要像ListView一样显示结果:
不喜欢这样:
无论我在模板上指定什么,即:{% for i in found_entries %}
<li><a href="{{ q.get_absolute_url }}">{{i.cedula}}{{i.nombre}}{{i.usuario}}</a></li>
{% endfor %}
它都会一直显示结果。
如何像ListView一样显示它们?
有什么想法吗?
