Django Postgresql 搜索不显示结果

问题描述

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。
