   • Render(request, Template_name,[dictionary],[context_instance],[content_type],[status],[current_app],[dirs]): Returns the HttpResponse object with the given context fill template, which is the content of the template after it is replaced. Render () function with Context_instance (RequestContext) The Render_to_response function is the same for the parameter invocation

      render   #如下代码功能相同from django.shortcuts import  renderdef My_    View (Request): # View Code here ... return  render (Request, ' myapp/index.html ', {"foo : "bar "}, content_type= "application/ Xhtml+xml  ") from django.http import  httpresponsefrom django.template Span style= "COLOR: #0000ff" >import  RequestContext, loaderdef my_view (Request): # View Code here ... t = Loader . Get_template (' myapp/index.html ') c = requestcontext (request, {' foo ': ' Bar '}) return HttpResponse (T.render (c), content_type= "application/xhtml+xml ")  /pre>

   • Render_to_response(template_name[, dictionary][, context_instance][, content_type][, dirs]): Fills the template with the given context and returns HttpResponse object,
