带有错误的查询字符串“以10为基数的int()无效文本”

I was trying to get a Model object from datastore using the key passed from query string. It worked before that, however, recently, when I named the file from restaurantProfile.html to restaurant_profile.html. I don't know from which part went wrong caused the problem.

我试图使用查询字符串传递的键从datastore获取模型对象。然而，在此之前，我从餐馆的档案中命名了这个文件。restaurant_profile.html html。我不知道是哪里出了问题造成了这个问题。

My restaurant key should contains the key. However, from the GAE log, I've set custom debug to see what contains in Restaurant key passed to my handler (Result):

我的餐厅钥匙应该有钥匙。但是，从GAE日志中，我设置了自定义调试，以查看传递给我的处理程序(结果)的Restaurant key中的内容:

GAE Log:
Restaurant Key = <bound method Restaurant.key of <persistence.model.Restaurant object at 0x5cd3c5acd5768900>>

Can anyone tell me what's got wrong here? The restaurant key doesn't seem to be passed to the handler.

谁能告诉我这里出了什么问题吗?餐厅的钥匙似乎没有传递给管理员。

<a href="/restaurant_profile?restaurant_key={{ key }}">

Handler Class:

处理程序类:

class RestaurantProfileHandler(webapp.RequestHandler):
def get(self):
    restaurant_key = self.request.GET.get(u'restaurant_key')

    logging.debug('Restaurant Key = %s', restaurant_key)

Error: "invalid literal for int() with base 10" for following:

错误:“以10为基数的int()无效文字”

def get_RestaurantDetails(restaurant_key):
   if restaurant_key:

it's exactly like it says: restaurant_key is a method. You can't call int() upon that; did you mean to call int() upon the result of calling restaurant_key()?

就像它说的:restaurant_key是一个方法。不能调用int();您的意思是在调用restaurant_key()的结果之后调用int()吗?

As for why restaurant_key is a method, well, that's what self.request.GET.get(u'restaurant_key') returned. Maybe you should re-read the documentation...

至于为什么餐馆钥匙是一种方法，嗯，这就是self。request。get.get (u'restaurant_key')返回的原因。也许你应该重读一下文档……
