If its not possible is there a way to contain a list of data that can
be added to by the app.
If I understand correctly you want to put the contents of an entire
array into a single record in a table. Whilst this is possible by
encoding the contents into a string this is often not the best
solution to the underlying problem. Give us some more details of what
you are trying to achieve, there may be a better way, using has_many
and belongs_to relationships for example. It might be worth your
while first looking at the rails guides on ActiveRecord relationships
at http://guides.rubyonrails.org/ (and also Getting Started if you
have not already seen that one). These might give some ideas on
alternative solutions.
