Question

I’m retrieving a param in a controller from a form, from which I want to remove a hash and put into a variable for later use.

Let’s assume the param include the following:

@form_data = params[:project] // <-- :id, :title, :description, :members

‘:members’ is an array (retrieved from checkboxes) and I want that array to be put in a new variable for later use, and it should be removed from the param.

@members // <-- should contain :members 

@project = Project.new(params[:project])  // <-- ':members' is removed

How could this be done?

Answer 1

You can use delete method

@members = params[:project].delete(:members)
@project = Project.new(params[:project])
