我正在尝试在 3 个字段名称、类别和标签中对我的对象使用搜索，所以现在类似项目三次

Question

views.py

 if search:
     wallpapers = Wallpaper.objects.filter(Q(name__icontains=search) | Q(category__category_name__icontains=search) | Q(tags__tag__icontains=search))

Html代码

<form method="GET" action="/" class="d-flex">
  <input class="form-control me-2" name="search" id="search" type="search" placeholder="Search"
                    aria-label="Search">
  <button class="btn btn-outline-success" type="submit">Search</button>
</form>

Answer 1

有可能类别和标签都匹配，因此互为“乘数”。您可以使用 .distinct() [Django-doc] 检索唯一项目：

if search:
    wallpapers = Wallpaper.objects.filter(
        Q(name__icontains=search) | Q(category__category_name__icontains=search) | Q(tags__tag__icontains=search)
    )<strong>.distinct()</strong>

我正在尝试在 3 个字段名称、类别和标签中对我的对象使用搜索，所以现在类似项目三次
