所以我正在处理保存配置文件功能,我不知道为什么我会收到以下错误:

__init__() takes at least 3 arguments (3 given)


这是它发生的功能(在它到达self.profiles.update line之后):

@view_config(route_name="profile", request_method='POST')
def save_profile(self):
    try:
        json = self.request.json_body
        #username = str(json['userName'])
        first_name = str(json['firstName'])
        last_name = str(json['lastName'])
        phones = str(json['phones'])
        emails = str(json['emails'])
        self.profiles.update(self, firstName=first_name, lastName=last_name, emails=emails, phones=phones)
        value = {'result:': 'success', 'message': 'Profile Saved!'}
        self.respond(value)
        return self.route('profile')
    except Exception, err:
        print err
        value = {'result:': 'error', 'message': 'There was an error processing the request'}
        self.respond(value)
        return self.route('profile')

我在项目范围内搜索 init ,这似乎是唯一匹配的函数

class WhoView(Extension):
    def __init__(self, context, request):
        self.session = request.session
        self.request = request
        self.status_code = 200
        self.content_type = "text/html"
        ctx = self.session.ctx
        self.request_context = context

        Extension.__init__(self, ctx)

    def attach_session(self, token):
        self.ctx.attach_session(token)

有什么想法?您需要了解的其他信息?

你没有在任何地方重定向(self.route进行重定向)。此外,您无法在此重定向,因为您正在进行ajax调用。我很确定电话和电子邮件的分配是不正确的,因为你正在将数组转换为字符串。我们明天会在办公室谈谈这件事。同样正如sza所指出的那样,你不会为方法调用传递self。

@view_config(route_name="profile", request_method='POST')
def save_profile(self):
    try:
        json = self.request.json_body
        #username = str(json['userName'])
        first_name = str(json['firstName'])
        last_name = str(json['lastName'])
        phones = str(json['phones'])
        emails = str(json['emails'])
        self.profiles.update(firstName=first_name, lastName=last_name, emails=emails, phones=phones)
        value = {'result:': 'success', 'message': 'Profile Saved!'}
    except Exception, err:
        print err
        value = {'result:': 'error', 'message': 'There was an error processing the request'}

    #returns a json response
    return self.respond(value)

不是

self.profiles.update(self, firstName=first_name, lastName=last_name, emails=emails, phones=phones)

应该是

self.profiles.update(firstName=first_name, lastName=last_name, emails=emails, phones=phones)
