I would love a full drop-in answer (hand me a fish), but I this might be a
matter of pointing me to where I need to RTFM (teach me to fish).
I have a form with a text_area:
<%= f.text_area :modified_strategy, :options=>{:cols => 80} %>
the string represented by :modify_strategy is comprised of a pattern:
<many words>;<more words>;<maybe even more words>;
This string is a representation of what was originally three lines with
"\n".
So to properly render them in a text_area I would want to do something like:
gsub(";","\n")
and then reverse this in the Model before_save.
Unfortunately something as simple as
... :modifed_strategy.gsub(";", "\n") ...
returns an error:
undefined method `gsub'' for :modified_strategy:Symbol
How do I change ";" to "\n" on the string represented by
:modified_strategy?
Where to next because I guess I''m really missing something about
Symbols or
Views.

The :modified_strategy is just a symbol that tells the helper which method
to call on your object to get the name/value of the textarea.
If you want to manually change the value of the textarea, you can overwrite
the value attribute:
f.text_area(:modify_strategy , :value =>
f.object.modify_strategy.gsub(";",
"\n"), :cols => 80)
