Я использую Django версии 2.
Я работаю над веб-приложением блога, используя базу данных PostgreSQL.
Я пытаюсь добавить функцию поиска в веб-приложение, но когда открываюURL (http://localhost:8000/search/), чтобы выполнить поиск, я получаю ошибку ниже.
Страница не найдена (404) Метод запроса: GET URL запроса: http://localhost:8000/search/ Поднято: blog.views.post_detail Нет Сообщение соответствует заданному запросу.
вот блог / urls.py
from django.contrib.postgres.search import SearchVector
from .forms import CommentForm, SearchForm
from .models import Post, Comment
from django.shortcuts import render, get_object_or_404
from django.urls import path
from . import views
urlpatterns = [
path('', views.PostListView.as_view(), name='home'),
path('<slug:post>/', views.post_detail, name='post_detail'),
path('<int:post_id>/share', views.post_share, name='share'),
path('search/', views.post_search, name='post_search'),
]
вот views.py
def post_detail(request, post):
post = get_object_or_404(Post, slug=post)
comments = post.comments.filter(active=True)
new_comment = None
if request.method == 'POST':
comment_form = CommentForm(data=request.POST)
if comment_form.is_valid():
new_comment = comment_form.save(commit=False)
new_comment.post = post
new_comment.save()
else:
comment_form = CommentForm()
return render(request, 'detail.html', {'post': post,
'comments': comments, 'new_comment':
new_comment,'comment_form': comment_form})
def post_search(request):
form = SearchForm()
query = None
results = []
if 'query' in request.GET:
form = SearchForm(request.GET)
if form.is_valid():
query = form.cleaned_data['query']
results = Post.objects.annotate(
search=SearchVector('title','body'),
).filter(search=query)
return render(request, 'search.html',
{'form':form,'query':query,'results':results})
Вотфайлы шаблонов.
Для search.html - (страница для запроса)
