Rails - Dec 2006 - using params in view or setting the value in controller?

If i pass a param like params[:bid], should I do something like @bid
params[:bid] and then use @bid in the code. Or should I just use
params[:bid] in the actual view?

Using params[:bid] directly is fine, mostly. as long you feel 
comfortable with using whatever is in the url, not modified at all.

Often though, you want to validate or alter that data.  In those cases 
it''s better to assign it to an instance variable so you can be sure
it''s
the data after alteration and validation, rather than what ever is in 
the url.

I''d highly recommend divorcing the views from the params hash.

If you choose to change the param name, why should the view need to  
be changed?

What if you decide that value needs to stored in the session rather  
than passed as a param, for instance?

Hi Alex,

Thanks for the response. The only thing that annoys me is that if i have 
params[:all], i have to put that in everwhere cuz its kinda long a 
repetitive, whereas setting @all=params[:all], i could just use @all.

Im wondering what other people do on this?
