龙卷风render（）-参数过多

Question

I'm using render() to pass in a url and an additional variable but I get this error:

TypeError: render() takes exactly 2 arguments (3 given)

My code is:

class CloseHandler(tornado.web.RequestHandler):   
    def get(self):       
        ui=db.users.find_one({"Username": ui0})
        ui1 = ui["Username"]        
        self.render("thanks.html" , ui1)

Answer 1

您可以使用self.render("thanks.html" , ui1) 。它们表示不同的含义。第一个ui1是template_name，第二个ui1是dict：ui1。
