Hi Everybody,
I am a newbie in this list so please forgive me if this is a lengthy
message.
Currently I am working on a project at my work place that includes
viewing some oracle tables(I do not have control over to rewrite the
tables) and searching the tables based on a given criteria with Rails.
Up untill now everything was working great. The database consists of a
lot of tables but I was working with five of them. Then I realized that
one of the fields in a table was referring to another table in the
database. For example if I had a DN (Directory Number) in the table,
that three digit DN was referring to another table being an actual DN.
So I decided to add that table. The actual name of the table is cfg_dn
(Legacy) with the following assignments I created the model/controller
and view
*/ruby script/generate scaffold cfg_dn cfg_dn
/*Again, up untill now everything that I wanted to do with the database
was working properly. I went ahead and typed the following to my browser
to see if I am hitting the table.
/*http://localhost:3000/cfg_dn*/
To my amazement the error I got:
NoMethodError in Cfg_dn#index
undefined method `empty?'' for 3:Fixnum

Also please note that when i do the same thing for the previous five
tables, it works. It is just this table that I am having problem with.
And another thing is that I am able to see this table using Brio
Software (This software allows you to put together tables and do some
queries on it). So the table is definetely there and the contents are
definetely there.
I do not know what this error means and I do not know how to fix it.
Could any one give me some suggestions?
I would be more than happy to give more information if necessary.
Thanks a lot
Deniz Rende.

You call a method empty? on a number. Numbers don''t have this method: 4.empty? => ERROR! Arrays do: [1, 2, 3].empty? => false [].empty? => true Note that the number may also be in a variable: num = 5 num.empty? Jules -- Posted via http://www.ruby-forum.com/.

Scaffold help says: >ruby script\generate scaffold Usage: script/generate scaffold ModelName [ControllerName] [action, ...] So, I don''t think you want "cfg_dn". The first arg after scaffold should be your model name in camel case. Then, the controller, *if* you need it to have a different name. Ruby best practices also discourage abbreviations for class names, so I wouldn''t call your model CfgDn. I imagine you''re using that because that''s a table name. I think in this case you''ll need to override the default naming and tell the model what table you''re using with "set_table_name cfg_dn". Hope this helps, b

As a matter of fact, the other tables are named like this too. For example the table names are gcdr, scdr, evref, evrefex, and arec. I had to use "set_table_name ..." for each of them to override.I googled this error but could not come up with anything... Thanx....

That is the "weirdness" of the error. I am just adding a new table to the application in the same way I did for the other ones... Any suggestions?
