render :action => "new"和render :template => "users/new"之间有什么区别？我听说渲染模板，我们可以用于其他控制器的视图.这是真的吗？还是两者在渲染布局上有什么不同？对于render:template，是否有必要定义一个操作，或者查看页面本身就足够了？

There is no difference.
render :template => 'some/thing' is the same as just render 'some/thing', as well as the same as render :action => 'thing' if we are in the some controller.
render :edit
render :action => :edit
render 'edit'
render 'edit.html.erb'
render :action => 'edit'
render :action => 'edit.html.erb'
render 'books/edit'
render 'books/edit.html.erb'
render :template => 'books/edit'
render :template => 'books/edit.html.erb'
render '/path/to/rails/app/views/books/edit'
render '/path/to/rails/app/views/books/edit.html.erb'
render :file => '/path/to/rails/app/views/books/edit'
render :file => '/path/to/rails/app/views/books/edit.html.erb'
