Access controller var within model


#1

I need to access params[:field_name] from within my Model.
@params[:field_name] isn’t working?

Why would you need to access that??

There is probably a better way to do it

That smells like very tight coupling between view and model. @params
hash is something that belongs to the controller and individual http
requests, not your model objects. Remember that AR is a totally
distinct entity in Rails, and doesn’t know anything about what is
happening on the controller/view side. If you got something you need to
pass to the AR models, create a method where you can pass the value of
the current params[:field_name].

Sorry, I just needed to access the AR object, I thought i needed to use
@params[]
but I soon figured out what you mentioned above and was able to access
‘field_name’
as a local var, This clarifies things quite alot. thx.

It isn’t, and it shouldn’t.
