对我来说，现在的任务是使用mongodb创建搜索栏
我到目前为止所做的事情>
from pymongo import MongoClient
def mongosearch(title=""):
connection = MongoClient('localhost',27017)
db = connection.djangodb
collection = db.spiderCollection
title = collection.find()
for title in titles:
pprint.pprint()
from django.shortcuts import render
from django.http import HttpResponse
from .mongodb_connection import mongosearch
from .models import AppModel
# Create your views here.
def search_view(request):
results = []
title_term = ""
search_term = ""
titles = AppModel.objects.all()
if 'search' in request.GET:
search_term = request.GET['search']
titles = titles.filter(title__icontains=search_term)
results = mongosearch(title=title_term)
print(results)
context={
'results':results,
'count':len(results),
'search_term':search_term,
'titles':titles
}
return render(request, 'search.html', context)
from django.db import models
class AppModel(models.Model):
title = models.CharField(max_length=100, primary_key=True)
desc = models.CharField(max_length=100)
url = models.CharField(max_length=100)
class Meta:
db_table = "spiderCollection"
from django.urls import path, include
from . import views
from django.conf.urls import url
app_name = 'searchapp'
urlpatterns=[
path('',views.search_view, name='search_view'),
]
