Question

I’ve got a legacy database that I’m connecting to via the sqlserver adapter. One of the databases is called “SiteIndex_Players”. I’ve generated the following model:

class SiteIndexPlayer < ActiveRecord::Base
  set_table_name = "SiteIndex_Players"
end

I’ve also tried:

class SiteIndexPlayer < ActiveRecord::Base
  table_name = "SiteIndex_Players"
end

Both ways, when I run the rails console rails c, I get this:

1.9.2-p290 :001 > SiteIndexPlayer.first
SiteIndexPlayer Load (352.1ms)  EXEC sp_executesql N'SELECT TOP (1) [site_index_players].*    FROM [site_index_players]'

Makes sense, the table is “SiteIndex_Players”, not “site_index_players” (notice the missing underscore).

Is there a way I can define the table to have the name “SiteIndex_Players”?

Thanks

Answer 1

Instead of

set_table_name = "SiteIndex_Players"

you need

set_table_name "SiteIndex_Players"

without the equals sign.
