問題描述
Wagtail Django‑form編輯現有對象 (Wagtail Django‑form edit existing object)
我正在按照 GitHub 上的 wagtail‑form‑example 將 Django 表單實現到 wagtail 中。除了能夠編輯現有提交之外，我已經完成了所有工作。
這是我到目前為止所遵循的代碼 https://github.com/gasman/wagtail‑form‑example/blob/master/flavours/models.py
我嘗試了以下幾種變體代碼。
def serve(request, id):
instance = get_object_or_404(MyModel, id=id)
form = MyForm(request.POST or None, instance=instance)
如果有幫助，我會收到以下消息：int() 參數必須是字符串、類似字節的對像或數字，而不是“builtin_function_or_method”
任何幫助/示例將不勝感激:)
參考解法
方法 1:
Changing def serve(self, request): to def serve(request, id): doesn't work that way.
Your second argument id now holds the request object and not the expected int like the error tells you.
Start by respecting the method arguments serve(self, request). That means you need to query your form in some other way.
Eg: get_object_or_404(MyModel, id=[some hardcoded id])
If you want any form to be shown as child of your page, you could use RoutablePageMixin add an url relative to your page. Eg:
@route(r'^(\d+)/$')
def form_view(self, request, form_id=None):
instance = get_object_or_404(MyModel, id=form_id)
