I am trying to get to grips with the params hash in RoR. I’m not sure if I’m missing something, but my understanding so far is that the params hash is a hash containing either form entered data or query string data related to a POST request. Where params[:item] creates a symbol where the relevant POST data/query is stored. Again not sure if I’m correct on this, any enlightenment would be much appreciated. Thanks
The params hash is described in detail in the Action Controller Overview. TL;DR: the params hash holds all GET or POST parameters passed to the controller, as well as the :controller and :action keys.
