Django跨多个模型搜索/过滤

如何解决Django跨多个模型搜索/过滤

在我的Django网站中，我试图在主页上创建一个搜索栏，以返回存储在两种不同模型（文章，乔布斯）中的结果

当前，当我使用以下代码进行搜索时会得到一个空结果集：

在models.py中，

class Articles(models.Model):
    objects = None

    news_title = models.CharField(db_column="title",max_length=400)
    news_url = models.URLField(db_column="link",max_length=400)
    image_link = models.CharField(db_column="image",max_length=400)
    published_date = models.CharField(db_column="published_date",max_length=400)

    class Meta:
        managed = False
        db_table = "articles"

    def __str__(self):
        return self.news_title


class Jobs(models.Model):
    objects = None

    company = models.CharField(db_column='company',max_length=100)
    job_title = models.CharField(db_column='job_title',max_length=300)
    experience = models.CharField(db_column='experience',max_length=300)
    edu_level = models.CharField(db_column='edu_level',max_length=50)

    class Meta:
        managed = False
        db_table = "job_list"

    def __str__(self):
        return self.job_title

在views.py中，

class SearchView(ListView):
    template_name = 'blog/search_results.html'

    def get_queryset(self):
        request = self.request
        query = request.GET.get('q','')

        articles_results = Articles.objects.filter(Q(news_title__icontains=query))
        jobs_results = Jobs.objects.filter(Q(job_title__icontains=query))

        context={
            'articles':articles_results,'jobs':jobs_results,}

        return render(request,'blog/search_results.html',context)

在main_view.html中，我使用以下代码创建搜索栏：

<form action="{%url 'search_results' %}" method="get" values="{{request.GET.q}}" class="search-jobs-form">
    <div class="row mb-5">
         <input name="q" type="text" values="{{request.GET.q}}" placeholder="search">
    </div>
    <button type="submit">Search</button>
</form>

在search_results.html中，

{% block content %}
    {% for job in jobs %}
        <h5>{{job.job_title}}</h5>
        <p>{{job.company}}</p>
    {% endfor %}

    {% for article in articles %}
        <h5>{{article.news_title}}</h5>
        <p>{{article.published_date}}</p>
    {% endfor %}
{% endblock %}

解决方法

我最终没有在views.py中使用类SearchView（ListView）并使它工作

这是我使用的代码

#index.html Search Bar
<form method="get" class="search-jobs-form" action="{% url 'main_search'%}">
    {% csrf_token %}
    <input type="text" placeholder="Job title,Company..." name="search_query">
    <button type="submit" class="btn btn-info btn-lg btn-block text-white btn-search">Search Job</button>
</form>

在视图中，

#views.py
def main_search(request):
    q = request.GET['search_query']

    articles = Articles.objects.filter(news_title__icontains=q)
    jobs = Jobs.objects.filter(Q(job_title__icontains=q) | Q(company__icontains=q))
    return render(request,"blog/main_search.html",{'articles':articles,'jobs':jobs,'page_name':'Search Results','q':q})
