什么是敏捷开发

一种应对快速变化的需求的一种软件开发能力。

强调

• 程序员团队与业务专家之间的紧密协作
• 面对面的沟通（认为比书面的文档更有效）
• 频繁交付新的软件版本
• 紧凑而自我组织型的团队
• 很好地适应需求变化的代码编写和团队组织方法
• 软件开发中人的作用

工具

• Git

  • 版本控制
  • 缺陷报告

• Trello

  • 进度跟踪
  • 工作分配

• 持续集成

Web敏捷开发

网站主要组成部分

• 数据库
• 业务逻辑
• 访问控制
• 前端设计

我的选择

Django

+

Bootstrap

Django

The Web framework for perfectionists with deadlines.

Django makes it easier to build better Web apps more quickly and with less code.

ORM

Object-relational mapper

• 用于实现面向对象编程语言里不同类型系统的数据之间的转换

避免手写复杂的SQL语句和常见SQL注入场景

  from django.db import models
  from ckeditor.fields import RichTextField

  class Pages(TimeStampedModel):
      """
      Pages
      """

      title = models.CharField(verbose_name='标题', max_length=100)
      content = RichTextField(verbose_name='内容', config_name="default")

      mark = models.CharField(verbose_name='唯一标志', unique=True, max_length=20)

      class Meta:
          verbose_name = "页面"
          verbose_name_plural = "  页面"

      def __unicode__(self):
          return self.title
        

通过面向对象编程的方式操作数据库

  class TimeStampedModel(models.Model):
      """工具类
      用来给你的model添加下面两个字段，分别是创建时间和更新时间
      Usage: class YourModel(TimeStampedModel): ...
      """

      created_date = models.DateTimeField(verbose_name='创建时间', auto_now_add=True)
      updated_date = models.DateTimeField(verbose_name='更新时间', auto_now=True)

      class Meta:
          abstract = True
        

Admin Site

简单配置即可拥有完备后台

高度可定制

          class DownloadAdmin(admin.ModelAdmin):

          list_display = ('name', 'description', 'download_link', 'created_date')
          list_filter = ('created_date',)
          search_fields = ('name', 'description', )
          form = forms.UploadFileForm

          fieldsets = (
          (None, {
          'fields': ('document', 'description')
          }),
          ('Advanced options', {
          'classes': ('collapse',),
          'fields': ('name',)
          }),
          )

          def download_link(self, obj):
          link = "<strong><a href={0}>下载</a></strong>".format(reverse('file',
          kwargs=dict(file_id=obj.id)))
          return mark_safe(link)
          download_link.short_description = "下载链接"

          def delete_model(self, request, obj):
          storage, path = obj.document.storage, obj.document.path
          super(DownloadAdmin, self).delete_model(request, obj)
          storage.delete(path)

          admin.site.register(models.Download, DownloadAdmin)
        

Views

Django has the concept of “views” to encapsulate the logic responsible for processing a user’s request and for returning the response

Generic View

  class RegisterMeeting(generic.CreateView):
      """
       注册会议
      """
      model = models.Members
      template_name = "register.html"
      success_url = '/'

      def get_success_url(self):
          messages.success(self.request, "注册成功！")
          return reverse_lazy("index")
        

Templates

• Powerful
• Extensible
• Designer-Friendly
• Separate design, content and Python code.

Others

• Elegant URL design
• Cache System
• Internationalization(i18n)
• Security
• Common Web application tools

Bootstrap

简洁、直观、强悍、移动设备优先的前端开发框架，让web开发更迅速、简单。

One framework, every device.
