Django Postgresql 搜索不显示结果

如何解决Django Postgresql 搜索不显示结果

我正在制作一个 Django 网站，该网站具有使用 Postgres 的全文搜索。但是，当我进行搜索时，没有任何结果出现。我做错了什么吗？这是我的代码：

视图.py

from django.shortcuts import render
from django.contrib.postgres.search import SearchVector,SearchQuery,SearchRank
from django.views.generic import ListView,FormView
from .models import Post
from .forms import *

# Create your views here.

class HomepageView(FormView):
    template_name = 'selling/home.html'
    form_class = SearchForm

class Search(ListView):
    model = Post
    template_name = 'selling/search.html'

    def get_queryset(self):
        query = self.request.GET.get('q')
        posts = Post.objects.annotate(
            search=SearchVector('title','description'),).filter(search=SearchQuery(query))
        return posts

模型.py

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User

# Create your models here.
class Post(models.Model):
    title = models.CharField(max_length=100)
    description = models.TextField()
    date_posted = models.DateTimeField(default=timezone.Now)
    author = models.ForeignKey(User,on_delete=models.CASCADE)
    book_author = models.CharField(max_length=30)
    phone_contact = models.CharField(max_length=20)
    price = models.DecimalField(max_digits=7,decimal_places=2)
    postal_code = models.CharField(max_length=20)

    def __str__(self):
        return self.title

Forms.py

from django import forms

class SearchForm(forms.Form):
    q = forms.CharField(label='Search',max_length=50)

搜索.html

{% extends "selling/base.html" %}
{% load static %}
{% block content %}
<div class="container pt-5 pb-5">
    <div class="ui divided items">
        {% for item in posts %}
        <div class="item">
            <div class="image">
                <img src="{% static 'selling/images/brebeuf.png' %}">
            </div>
            <div class="content item-container">
                <a class="header item-title">{{ item.title }} </a><b class="item-price-right">${{ item.price }}</b>
                <div class="Meta">
                    <span>{{ item.postal_code }} &emsp; | &emsp; {{ item.date_posted|date:"d/m/Y" }}</span>
                </div>
                <div class="description item-description">
                    <p>{{ item.description }}</p>
                </div>
            </div>
        </div>
        {% endfor %}
    </div>
</div>
{% endblock content %}

home.html

{% extends "selling/base.html" %}
{% load static %}
{% block content %}
<form action="{% url 'search' %}" method='get'>
  {{ form }}
</form>
{% endblock content %}

settings.py - 已安装的应用

INSTALLED_APPS = [
    'selling.apps.SellingConfig','users.apps.UsersConfig','django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','django.contrib.postgres',]

urls.py

from django.urls import path
from .views import Search,HomepageView

urlpatterns = [
    path('',HomepageView.as_view(),name='sell-home'),path('search/',Search.as_view(),name='search'),]

这就是全部代码。如果您需要其他任何东西，请随时询问。
