I want to get table name in a model method. I found there should be method table_name but when I try to call it I get NameError Exception: undefined local variable or method `table_name'. It is obviously not there:
pp methods.grep(/^ta.*/)
["table_name_prefix?",
"table_name_suffix?",
"taint",
"taguri",
"taguri=",
"tainted?",
"table_name_prefix",
"table_name_suffix",
"tap"]
How to get a "real" table name (no lowecase - pluralize tricks)?
Thanks
