找不到 'delete_task/{{todo.id}}' 的反向。 'delete_task/{{todo.id}}' 不是有效的视图函数或模式名称
Reverse for 'delete_task/{{todo.id}}' not found. 'delete_task/{{todo.id}}' is not a valid view function or pattern name
我是 django 的新手,在 运行 之后我遇到了以下问题:
找不到 'delete_task/{{todo.id}}' 的反转。 'delete_task/{{todo.id}}' 不是有效的视图函数或模式名称。
在我的模板文件中 index.html 我有:
<form action="{% url 'delete_task/todo.id'%}" method="post" class = 'delete-link'>
{% csrf_token%}
<button type="submit">Delete</button>
</form>
我的urls.py:
urlpatterns = [
path('delete_task/<int:todo_id>', views.delete_task, name='delete_task'),
]
我的views.py:
def delete_task(request, task_id):
return HttpResponse(task_id)
#the delete_task block is just for test
谢谢
这样写:
<form action="{% url 'delete_task' todo.id %}" method="post" class = 'delete-link'>
{% csrf_token%}
<button type="submit">Delete</button>
问题解决
路径的名称是delete_task
,所以{% url … %}
template tag [Django-doc]的第一个参数是'delete_task
,那么第二个就是参数(此处todo.pk
):
<form action="<b>{% url 'delete_task' todo.id %}</b>" method="post" class = 'delete-link'>
{% csrf_token%}
<button type="submit">Delete</button>
</form>
