这是我的自定义类,它代表一个三角形.我正在尝试编写代码来检查是否self.a,self.b和self.c大于0,这意味着我有角度,角度,角度.

下面你将看到检查A和B的代码,但是当我使用self.a != 0它时,它工作正常.我相信我没有&正确使用.有任何想法吗？这是我如何称呼它:print myTri.detType()

class Triangle:

    # Angle A To Angle C Connects Side F
    # Angle C to Angle B Connects Side D
    # Angle B to Angle A Connects Side E

    def __init__(self, a, b, c, d, e, f):
        self.a = a
        self.b = b
        self.c = c
        self.d = d
        self.e = e
        self.f = f

    def detType(self):
        #Triangle Type AAA
        if self.a != 0 …

我是javascript开发的新手,当我通过backbone_blueprints书时,我遇到了以下错误.这是我得到的错误:

我有一些看起来像的代码

self = @

然后使用@someMethodName或self.someMethodName

@有一些特殊含义吗？

我想在我的Rails应用程序中使用一些Javascript.

我想让我的索引页面允许我编辑索引页面上的各个项目,然后在编辑时重新加载索引页面.

我的index.html.erb页面如下所示:

<div id="index">
<%= render 'index' %>
</div>

在我的index.js.erb中我有:

$('#index').html("<%=j render 'index' %>");

在我的holder_controller中:

def edit
  holder = Holder.find(params[:id])
 end

def update
  @holder = Holder.find(params[:id])
  if @holder.update_attributes(params[:holder])
    format.html { redirect_to holders_path } #, flash[:success] = "holder updated")
    ## ^---Line 28 in error
    format.js
  else
    render 'edit'
  end
end

当我加载索引页面时,它很好.只要单击编辑按钮并提交表单,我就会得到以下信息:

但是,如果我返回并刷新索引页面,则会保存编辑内容.我究竟做错了什么？

我要做的是让我的所有帖子都具有以下格式:domain.com/blog/title.

但是,在我的_posts文件夹中,我有一个名为的文件2010-07-11-hello.markdown,它包含以下内容:

---
title: Hello
permalink: /blog/:title/ 
---
Hello World!

我究竟做错了什么？永久链接未被转换.例如,URL看起来像这样:http://localhost:4000/blog/:title/我希望实际的标题显示在那里.

每当我从任何rails应用程序打开test.log时,我都会在Sublime中获得以下屏幕截图.我试过搞乱编码,但找不到任何修复它的东西.

关于发生了什么的任何想法？

每当我在我的域上收到404错误时,我想做什么,自动301到主页.

我有很多旧的博客文章和链接的,但我没有在博客上,如果有人碰巧从另一个网站点击,他们被踢到主页.

我怎么能在nginx里面这样做？

 server {
        listen             12680;
        root       /home/noahc/webapps/nginx/html/noahc/;
        server_name    www.noahc.net, noahc.net;
        error_page 404 @foobar;

        location @foobar {
                rewrite  .*  / permanent;
                }
         }

对于我的测试,我有以下内容:

test "should update holder" do
        holder = Holder.create(name: "name", user_id: 10)
        put :update, holder: holder
    assert_redirected_to holder_path(assigns(:holder))
end

当我运行它们时,我得到以下错误:

但在我的路线中,我有:

Teacherjoy::Application.routes.draw do
  get "users/new"

  resources :questions
  resources :pages
  resources …

我想构建一个基本上执行以下操作的机器人:

1. 收听房间并与用户互动,并鼓励他们下载机器人.
2. 一旦用户PMed,机器人就会使用各种AI技术与客户进行交互.

我应该只使用python中的IRC库或套接字,还是需要更多的机器人框架.

你会怎么做？

谢谢!

这是我目前正在使用的代码,但是,我没有让它工作.

#!/usr/bin/python 
import socket
network = 'holmes.freenet.net'
port = 6667
irc = socket.socket ( socket.AF_INET, socket.SOCK_STREAM )
irc.connect ( ( network, port ) )
irc.send ( 'NICK PyIRC\r\n' )
irc.send ( 'USER PyIRC PyIRC PyIRC :Python IRC\r\n' )
irc.send ( 'JOIN #pyirc\r\n' )
irc.send ( 'PRIVMSG #pyirc :Can you hear me?\r\n' )
irc.send ( 'PART #pyirc\r\n' )
irc.send ( 'QUIT\r\n' )
irc.close()

我目前正从开发服务器迁移到Apache Web生产服务器.

我已经尝试通过复制它来执行以下操作,我可以登录管理面板,但它没有显示.

我的app中的admin.py看起来像这样:

    import models
    from django.contrib import admin

    admin.site.register(models.Organization)

这是我的models.py

from django.db import models

class Organization(models.Model):
    name = models.CharField(max_length=100)
    website = models.URLField()
    azon_code = models.CharField(max_length=50)
    gooe_code = models.CharField(max_length=50)
    cj_code = models.CharField(max_length=50)

我已经重新启动了数据库并重新启动了apache以及可能会做某事.
