我试图遵循指南使用向导gem对对象进行部分验证,但我一直得到错误未定义的方法`include？' 对于nil:NilClass,无法理解有什么问题,已经尝试按照一步一步的说明进行操作.

日志中的错误显示.

NoMethodError - undefined method `include?' for nil:NilClass:
app/models/property.rb:22:in `active_or_tenants?'

这是我的步骤控制器.

class Properties::BuildController < ApplicationController
  include Wicked::Wizard

  steps :tenant, :confirmed 

  def show
    @property = Property.find(params[:property_id])
    @tenants = @property.tenants.new(params[:tenant_id])
    render_wizard
  end

  def update
    @property = Property.find(params[:property_id])
    params[:property][:status] = step.to_s
    params[:property][:status] = 'active' if step == steps.last
    @property.update_attributes(params[:property])
    render_wizard @property
  end

  def create
    @property = current_user.properties.build(params[:property])
      logger.info @property.attributes
    if @property.save
        flash[:success] = "Tenant Added"
        redirect_to wizard_path(steps.second, :property_id => @property.id)
    else
        render 'edit'
    end
  end
end

我试图从字典中的响应对象获取值,但我一直遇到这个错误,我认为你__getitem__更常用于类中的索引是错误的吗？

这是代码:

import json
import requests
from requests.auth import HTTPBasicAuth

url = "http://public.coindaddy.io:4000/api/"
headers = {'content-type': 'application/json'}
auth = HTTPBasicAuth('rpc', '1234')

payload = {
  "method": "get_running_info",
  "params": {},
  "jsonrpc": "2.0",
  "id": 0,
}

response = requests.post(url, data=json.dumps(payload), headers=headers,   auth=auth)


print("respone is: ", response['result'])

嗨，当我尝试使用另一个类的实例将新对象转换为字典时__dict__，我正在尝试使用组合来创建一个新类，它向我展示了<__main__.myobjec object at 0x00000000029CA908>，__dict__虽然我听说它与新类有关，但我不确定我是否使用错误，非常感谢任何帮助。

class User:

    def __init__(self, name, job=None):

        self.name = name
        self.job = job


class Customer(User):

    _ID = 100

    def __init__(self, name, job=None):

        self.name = name
        self.job = job


class Account:

    _ID = 0

    def __init__(self, name, job=None):

        self.customer = Customer(name , "Customer")

    def __getattr__(self, attr):

            return getattr(self.customer, attr)

>>> A = Account("Abdi")
>>> A.__dict__
{'customer': <__main__.Customer object at 0x109fdbfc8>}

我正在遵循协议缓冲区教程，但在编译时不断遇到不同的错误。我的addressbook.proto 文件位于/Users/flexmaster411/protobuffer

protoc -I=/Users/flexmaster411/protobuffer --python_out= /Users/flexmaster411/protobuffer/addressbook.proto /Users/flexmaster411/protobuffer

即使我的原型文件上有语法 =“proto3”，我仍然收到以下错误

[libprotobuf WARNING google/protobuf/compiler/parser.cc:471] No syntax specified for the proto file. Please use 'syntax = "proto2";' or 'syntax = "proto3";' to specify a syntax version. (Defaulted to proto2 syntax.)

不确定我是否正确完成了导致此问题的目标文件夹设置，感谢任何帮助

syntax = "proto3";

package tutorial;

message Person {
  string name = 1;
  int32 id = 2;        // Unique ID number for this person.
  string email = 3;

  enum PhoneType {
    MOBILE = 0;
    HOME = 1;
    WORK = 2;

当我尝试使用嵌套属性提交此表单时,我一直收到这个未定义的错误,不知道它来自哪里摔跤已经有一段时间了,我试图让用户在委员会模型中选择一个选项提交他们的选择,我不确定我是否正确连接了我的关联,或者错误是否来自表单.是铁路的菜鸟.提前致谢.
