如何在Django中使用块内的if语句进行图像检索

from django.shortcuts import render
from django.core.files.storage import FileSystemStorage

def image_search(request):
    if request.method == 'POST' and request.FILES['image']:
        image = request.FILES['image']
        fs = FileSystemStorage()
        filename = fs.save(image.name, image)
        uploaded_file_url = fs.url(filename)
        # 在这里进行图像检索的逻辑处理
        # 可以调用相关的机器学习/深度学习模型进行图像匹配或特征提取等操作
        return render(request, 'result.html', {
            'uploaded_file_url': uploaded_file_url
        })
    return render(request, 'image_search.html')

from django.urls import path
from . import views

urlpatterns = [
    path('image_search/', views.image_search, name='image_search'),
]

<form method="post" enctype="multipart/form-data">
  {% csrf_token %}
  <input type="file" name="image">
  <button type="submit">搜索</button>
</form>

<img src="{{ uploaded_file_url }}" alt="Uploaded Image">
