Deny partial controller control with Ruby On Rails

Question

Im using Rails 3 in my project.

In the controller> articles In sight> index.html.erb

<% if @articles.blank? %> <%= render :partial => "blank" %> 

I don’t want to write requests in views for verification (if it is empty or to do it) How can I pass an empty partial slider (if the set of requests is empty) inside the controller?

Thanks.

Answer 1

You can also make a switch in the controller.

 def index @articles = Article.all render "index_without_articles" if @article.nil? end 

Answer 2

I believe you want render_to_string . See this blog post for more information on rendering in Rails 3.

Answer 3

this may be a workaround, but it's a pretty simple solution

 <%= render :partial => "blank_#{@articles.blank?}" %> 

and have two elementary elements called _blank_true.html.erb and _blank_false.html.erb
