Here is how my restful new action look like:

def new  
@foo = @widget.build(params[:foo])  
raise NoPost unless request.post?  
@foo.save!  
respond\_to do |type|  
type.html { redirect\_to foo\_url }  
type.js { render :action =\> :create }  
end  
rescue NoPost  
respond\_to do |type|  
type.html { render :action =\> :new }  
type.js { render :partial =\> ‘form’ }  
end  
rescue ActiveRecord::RecordInvalid  
respond\_to do |type|  
type.html { render :action =\> :new }  
type.js { render :action =\> :create }  
end  
end  
alias :create :new

Any ideas how to DRY it?

Ah sorry, didn’t notice. There’s not much to DRY tho in that case. Try  
this:

rescue NoPost, ActiveRecord::RecordInvalid  
[…]  
type.js { render :action =\> ($!.is\_a? NoPost) ? :new : :create }

Just typing this out, but some variation of that will work.
