如何在ListView Django中使用表單？

Question

我正在嘗試爲ListView創建一個動作，該動作將是刪除或更改模型中表中的參數，例如，使用複選框禁用用戶。 如果我選擇了所有它們並單擊此按鈕，它將被全部刪除。

** views.py

class AccountsManagementView(LoginRequiredMixin, generic.ListView): 
    """ 
    Class Based View para a manipulação de usuários. 
    """ 
    model = User 
    template_name = 'accounts/accounts_management.html' 
    context_object_name = 'users' 


    def get_queryset(self): 
     return User.objects.all() 

class DeleteUser(DeleteView): 
    model = User 
    success_url = reverse_lazy('accounts:accounts_manager') 

** urls.py

urlpatterns = [ 
    # ListView dos Usuarios 
    url(r'^$', views.accounts_management, name="accounts_manager"), 
    # Deletar Usuario 
    url(r'^(?P<pk>\d+)/deleteuser/$', views.delete_user, name="delete_user"), 
    # Add Usuario 
    url(r'^adicionar_usuario/$', views.accounts_form, name="accounts_form"), 
    # Update Usuario 
    url(r'^editar/(?P<username>[\w_-]+)/$', views.account_edit, name="accounts_edit"), 
    # Visualizar perfil usuario 
    url(r'^visualizar/(?P<username>[\w_-]+)/$', views.account_view, name="accounts_view"), 
] 

模板/ accounts_management.html

<form action="" method="post"> 
<div class="panel panel-default">

Answer 1

你可以做的是使窗體回報您要刪除的對象的pk列表。

然後，你做這樣的事情：

def delete_view(request): 
    if request.method == "post": 
     data = [] # Array of pks 
     User.objects.filter(pk__in=data).delete() 

這應該做什麼你問。

如果這樣做對你沒有幫助，也許谷歌批量刪除Django。似乎是過去出現的功能，但不再支持。

Answer 2

查看generic.UpdateView，瞭解使用post（）方法的CBV示例。它是在那裏你會帶來一個表格，驗證輸入，並處理 - 在你的情況下，看着每個複選框的價值，並相應地處理記錄。

除非您希望使其可重複使用，否則您可能不需要將邏輯分解爲與通用View相同的方法。
