I am facing bit of difficulty in making search page work. The problem is my template and view throwing data on search page. And my search button function doesnt works. If some one can have a look and advise what i m missing would be highly appreciated.
谢谢.
这是我的搜索页面看起来多么难看
this is how ugly my search page looks
- 以下是我的观点:
from django.shortcuts import render
# Create your views here.
#from django.shortcuts import render
from django.http import HttpResponse
from .mongodb_connection import mongosearch
from .models import AppModel
from django.db.models import Q
# Create your views here.
def search_view(request):
model = AppModel
template_name = 'search.html'
results = []
title_term = ""
desc_term = ""
search_term = ""
url_term = ""
titles = AppModel.objects.all()
url = AppModel.objects.all()
if 'search' in request.GET:
search_term = request.GET['search']
titles = titles.filter(
Q(title__icontains=search_term) |
Q(desc__icontains=search_term)
)
titles = AppModel.objects.all()
results = mongosearch(title=title_term
#,desc = desc_term)
)
print(results)
context={
'results':results,
'search_term':search_term,
'titles':titles
}
return render(request, 'search.html', context)
- 跟随html页面
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css"
integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
<!doctype html>
<html>
<nav class="navbar navbar-light bg-light">
<form class = "form-inline my-2 my-lg-1" method = "GET">
<!--action = "{%url 'search_view'%"> -->
<input
class="form-control mr-sm-2"
type="search"
placeholder="Search"
aria-label="Search"
name = 'search'
value = "{{request.GET.search}}">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
<br><br>
{% if titles %}
<ul class="messages">
{%for i in titles %}
<li class = "list-group-item">
{{i.title}}
</li>
{% endfor %}
</ul>
{% endif %}
</nav>
</html>
- mongo_connection
from pymongo import MongoClient
from pprint import pprint
def mongosearch(title=""):
connection = MongoClient('localhost',27017)
db = connection.djangodb
collection = db.spiderCollection
titles = collection.find()
for title in titles:
pprint(titles)
推荐答案
看起来您正在用视图中的所有对象覆盖已过滤的查询集.您需要删除多余的行:
Looks like you are overwrite filtered queryset with all objects in your view. You need to remove redundant line:
search_term = request.GET['search']
titles = titles.filter(
Q(title__icontains=search_term) |
Q(desc__icontains=search_term)
)
titles = AppModel.objects.all() # remove this line to not overwrite list
results = mongosearch(title=title_term
#,desc = desc_term)
)
print(results)
