Removing session element

rubyonrails-talk

Hello All,

I have an array:-

session[:new] = Array.new

session[:new] = [1, 2, 3, 4] - I am keeping these object ids in session.

I want to delete one id from the session - as session[:new] = [1, 2, 3]

How to delete one of the ids ?

Thanks,

Avi

Off the top of my head:

session[:new].reject!{|n| n == 4}

Given recent discussions, I'm sure there's a better way!

I was doing it wrong.

session[:new] = [1, 2, 3, 4]

session[:new].delete(1).to_i (Here I was not converting into integer).

The params values I was getting in the form of String.

Thanks for replying. 330.gif

do you mean delete(1.to_i) ?

Sorry, you are right.

session[:new].delete(params[:something].to_i)
