Django - 根據用戶在表格中的選擇刪除實例

我有以下情況：在網站上的用戶區域，他可以在表格中看到他所有的房地產帖子。每個帖子都有一個「垃圾按鈕」。當他按下按鈕時，我想從數據庫中刪除他選擇的確切實例。Django - 根據用戶在表格中的選擇刪除實例

這是我擁有的HTML。請注意，我使用了一個視圖來訪問數據庫，然後從數據庫中刪除。但我不知道如何發送確切的參數來在數據庫中找到它。

我正在練習我在書中學到的東西，所以我不想去AJAX。

將<form>中的按鈕放入POST的視圖中，該視圖將刪除該實例。例如：

HTML

<form action="{% url 'delete_estate %}" method="POST"> 
{% csrf_token %} 
<input type="hidden" name="estate_id" value="{{ estate.id }}"> 
</form>

視圖

def delete_estate(request): 
    if request.method == "POST": 
     estate_id = request.POST['estate_id'] 
     estate = Estate.objects.get(id=estate_id) 
     estate.delete() 

     messages.success(request, "Estate deleted successfully!") 
     return redirect("/")

網址

... 
url(r'^delete-estate/$', views.delete_estate.as_view(), name='delete_estate'), 
....

對不起，但在這種情況下不起作用。單擊垃圾桶按鈕後有一個模式對話框。這是我的問題。我不知道如何將post_id帶入這個對話框。如果只有按鈕沒有確認，那麼你可以按照你的要求進行操作。 –

將模態的內部for循環WEL l以便每個房地產都有獨特的模式。請記住將模式的ID更改爲id="delete_{{ anuncio.id }}"之類的內容，並使用data-target="delete_{{ anuncio.id }}"使刪除按鈕激活相同的模式。從該模式中，您應該能夠完成Hybrid與表單所說的內容並訪問{{anuncio.id}}變量。

如果您還不知道，默認情況下已創建id。
