Where did this value in a form come from?
Newb here.
I have a form and a value that is being displayed ... and I have no idea
where the value came from.
I have done a
<%= debugger; '''' %>
in the form and, indeed, the debugger stops at the statement.
I have tried to trace through the code to see where the value came from
... and I gave up.
So ... what in Rails initializes the fields of a form?

I''m looking for 3 areas to work as dynamic assets:
image_path, javascript_path, and stylesheet_path
When I say dynamic, I mean that they will be dynamic through

I have a bad feeling asking this but I did not manage to find an answer

<%= debug comment["created_at"] %>
<% end %>
I expected comment to be a hash, but comment.keys or comment.values fail, as
