Getting input's value from a form

I am following a new tutorial just added to the upcoming book, Advanced Rails Recipes. The recipe is, "Process Recurring Credit Card Payments". The tutorial is great and I recommend picking up the PDF book.

Simply put, there is a card server, and a then your main application which is used to pass credit card numbers to the server.

The problem I am having, is how do I get the parameters from the form into the controller without storing them in the model? It would be easy if I was storing the credit card number and expiration date in the user model, but I am not for security, so I cannot call @user.credit_card number. I guess I need something like page["input_credit_card].value?

    if @user.save       self.current_user = @user       cc = CreditCard.create(:first_name => @user.first_name,         :last_name => @user.last_name,         :number => #pick up from the form,         :month => #pick up from the form,         :year => #pick up from the form,         :brand => #pickup from the form       )

If you just want a CreditCard instance but do not want to persist it to the database you can use:-

CreditCard.new(:first_name => @user.first_name,         :last_name => @user.last_name,         :number => #pick up from the form,         :month => #pick up from the form,         :year => #pick up from the form,         :brand => #pickup from the form )

Is that what you are asking or do you want to know how to pull the values out of the params hash?

If I could get the values without persist to the database, that would
be perfect. how can I do that?

You can just use the id of the tag to retrieve the value from the params hash, e.g.

Assuming you have something like this in your view:-

  <%= text_field_tag 'number' %>

You should be able to access it in your controller using:-

  :number => params['number']

Is that what you were after?

thanks Jabbslad, I forgot about just using text_field_tag
