Passing form information

rubyonrails-talk

Hello everyone I am new to RoR and I was wanting to know how to pass form information (first_name, last_name, phone_number, and email) to a session so that I can use them in another form later?

Thank you

Try

session[:firstname] = firstname;

Hope that helps.

Can I go session[:prospect] = params [:first_name, :last_name, :email, :phone_number]

Will this put them all in one session and allow me to pull them from that session later?

Hi Sean,

By default, you can use the hash either use the whole Hash or value of one key at a time to store and retrieve in another Hash But you can add this to your class to open HashWithIndifferentAccess and add “values” method for you

class HashWithIndifferentAccess def values(*indices) hash = {} indices.each {|i| hash[i] = self[i]} p hash hash end end

#Example a = {} a[:a] = 1 a[:b] = 2 a[:c] = 3 a[:d] = 4 a[:e] = 5

b = a.values(:a, :b)#{:a=>1, :b=>2} Please let me know if you have a doubts using the same

Why add that method when there's already a values_at method that does exactly that ?

How does the values_at method work?

Hi,

values_at method does not do the same as it returns a array and hence we cannot restore the values in a hash for later purposes BTW values_at can be used as a.values_at(:a, :b)

Oops, getting mixed up here. The method I meant was slice (which is a rails addition). If you do add a method, I wouldn't call it values, as that would overwrite the usual values method which might cause problems further down the line.
