'使用方法使用方法 'PowerDesigner->Tools->Execute Commands->Edit/Run Scripts 可以保存该脚本为:name2comment.vbs ' 把pd中那么name想自动添加到comment里面 ' 如果comment为空,则填入name;如果不为空,则保留不变,这样可以避免已有的注释丢失.

利用Django开发网站，可以设计出非常优美的url规则，如果url的匹配规则（包含正则表达式）组织得比较好，view的结构就会比较清晰，比较容易维护。 最简单的形式 [python] view plain copy print? <code> from django.conf.urls import patterns, url urlpatterns = patterns('', url(r'^articles/2003/$', 'news.views.special_case_2003'), url(r'^articles/(\d{4})/$', 'news.views.year_archive'), url(r'^articles/(\d{4})/(\d{2})/$', 'news.views.month_archive'), url(r'^articles/(\d{4})/(\d{2})/(\d+)/$', 'news.views.article_detail'), )</code> 其中，正则表达式中组匹配出来的结果可以作为positional parameters传递给view. 如果url是www.yourdomain/articles/2005/，则会匹配第二条规则，执行news.views.year_archive('2005'). 注意点 域名部分会被过滤掉
