Rails: Keeping a partial DRY when using locals -

i have partial being reused couple controllers.

right have partial set accept 2 objects don't want do.

-if @article   .main-inner     .article-header       .article-title         =@article.title       -if !@article.byline.blank?         %span#byline           =@article.byline       %span#timestamp         =@article.publish_date.strftime("%a, %b %d, %y %i:%m %z")     .article-content       =truncate(@article.content, :length => 600).html_safe -else   .main-inner     .article-header       .article-title         =article.title       -if !article.byline.blank?         %span#byline           =article.byline       %span#timestamp         =article.publish_date.strftime("%a, %b %d, %y %i:%m %z")     .article-content       =truncate(article.content, :length => 600).html_safe 

when @article

def show   @article = article.find_by_permalink(params[:permalink]) end 

when through locals

$("#article").html("<%= escape_javascript render(:partial => 'article/view', :locals => { :article => @newarticle }) %>") 

1) how can consolidate partial not use if @article.
2) in js. proper syntax rendering partials don't have :partial => 'article/view' , use :locals?

if partial should use article(local) instead of @article(not instant variable), , should pass in locals when render partial.

render(:partial => 'article/view', :locals => { :article => @article }) 

or

render(:partial => 'article/view', :locals => { :article => @newarticle })
