Question

我做了一个搜索栏，但是每当我在其中写东西时，链接就会显示http://127.0.0.1:8000/?srh=something，但我不明白为什么没有显示特定的picture with title。它向我显示了所有带有标题的图片，但我只想要带有标题的图片，并将其写为搜索栏的标题。在此代码中添加哪些内容？

index.html

{% load static %}
{% static 'images/fulls' as baseUrl %}
{% static 'images/thumbs' as hiUrl %}  

    <form class="new" method="GET" action="">
    <input type="text" placeholder='Search..' name="srh" value="{{request.GET.srh}}"> <br>
     <button type="submit" class="btn btn-danger"> Search </button>
    </form>

   <div>
    {% for dest1 in target1 %}
    {% if dest1 %}
     <div>
      <a href="{{baseUrl}}/{{dest1.img}}">
       <img src="{{hiUrl}}/{{dest1.img}}" alt="" />
       <h3>{{dest1.title}}</h3>
     </a>
   </div>
   {% endif %}
   {%endfor%}
  </div>

views.py

def index(request):
    query = request.GET.get('srh')
    if query:
        match = Destination.objects.filter(title__icontains=query)

        target1 = a, b= [Destination() for __ in range(2)]
        a.img = 'Article.jpg'
        b.img = 'Micro Tasks.jpeg'

        a.title = 'Article Writing'
        b.title = 'Micro Tasks'

        context = {
        'target1': target1,
       }
        return render(request, 'index.html', context)
    else:
       return render(request, 'index.html')

models.py

class Destination(models.Model):
    title = models.CharField(max_length=255)
    img = models.CharField(max_length=255)
    price = models.IntegerField()

我不明白您为什么使用a和b，但是我认为这可以解决问题

def index(request):
    query = request.GET.get('srh')

    if query:
        match = Destination.objects.get(desc=query)
        context = {
            'match': match,
        }

        return render(request, 'index.html', context)
    else:
        return render(request, 'index.html')

<div>
    { % if match %}
     <div>
      <a href="{{baseUrl}}/{{match.img}}">
       <img src="{{hiUrl}}/{{match.img}}" alt="" />
       <h3>{{match.title}}</h3>
     </a>
   </div>
   {% endif %}
  </div>

每当我在Django的搜索栏中键入内容时，如何使require对象可用？
