前两者区别stackoverflow给了较明确的答案

参考网址：http://stackoverflow.com/questions/5154358/django-what-is-the-difference-between-render-render-to-response-and-direc

自django1.3开始：render()方法是render_to_response的一个崭新的快捷方式，前者会自动使用RequestContext。而后者必须coding出来，这是最明显的区别，当然前者更简洁。

return render_to_response('blog_add.html',{'blog': blog, 'form': form, 'id': id, 'tag': tag},

context_instance=RequestContext(request))

return render(request, 'blog_add.html', {'blog': blog, 'form': form, 'id': id, 'tag': tag})

stackoverflow里还给了return direct_to_template(request, template_name, my_data_dictionary)这样一个例子，关于其解释：

direct_to_template() is designed to be used just in urls.py without a view defined in views.py but it can be used in views.py to avoid having to type RequestContext.

direct_to_template is something different. It's a generic view that uses a data dictionary to render the html without the need of the views.py, you use it in urls.py.

direct_to_template()还没用到过，不再赘述，留下此方法，备用

locals()用法：locals()可以直接将函数中所有的变量全部传给模板。当然这可能会传递一些多余的参数，有点浪费内存的嫌疑，对可读性有影响，不推荐。

return render(request, 'blog_add.html',locals())

那么长一段代码精简到三分之一的长度。有种爽歪歪的感觉！feel well !
