Rails - Dec 2005 - Maintaining DB reflection without scaffolding

Hi,

I would like to know if there is a way to maintain database reflection
for the ''new'' and ''edit'' views whilst
removing scaffolding?

I''m trying to create a webapp that will be somewhat maintainable by
colleagues (that aren''t necessarily web developers) through simple
manipulation of db table fields.

For example to add another field to the webapp for tracking another
tidbit of information, one would just have to add an additional column
in the db.

I''ve found that as soon as I remove the scaffolding, or try to override
the ''new'' or ''edit'' views, the db reflection
goes away.

Please excuse me if this is in the docs somewhere already, I wasn''t
able
to find it before posting here.

Thank you!

   Matt

Check out what Scaffolding does, it''s something like:

Model.columns.each do |c|
	# print field...
end

Check the docs at api.rubyonrails.org, they have all the details.

Phillip,

I forgot to mention that the db reflection also goes away when the
scaffolding is generated to disk. So the only way to have db reflection
that I''ve found so far is via "dynamic" scaffolding like the
following
in the controller:

	scaffold :foobar

I haven''t been able to find anything like your psuedo-code above in the
generated scaffolding or the API docs. Where do you say it should
reside?

Yes, the forms are statically generated, but the table listing isn''t.  
Generate scaffolding to disk and look in the table view. The code you  
want will be something like:

<% for column in Model.content_columns %>
   <p>
     <b><%= column.human_name %>:</b>
     <!-- form stuff here -->
   </p>
<% end %>
