Ok to instantiate an object in the View?

Question

Is it ok to instantiate an object in a View before passing it to a partial?

<%= render :partial => \"trade_new\", :locals => {:trade=>Trade.new(\"e\"         


        

Answer 1

Firstly, it is okay to instantiate an object in the view. Nothing will probably blow up in your face. However, then you miss the whole advantage of splitting your architecture into tiers.

It is better to instantiate the object in the controller. Some of the reasons include - better reuse, much simpler testing, better design because of the decoupling.
