AR#column_names doesn't get all columns
Reported by le_fnord | May 11th, 2011 @ 11:10 AM
on some tables I have the error "column doesn't exist", but they do.
I found the error in AR/base ... see diff:
diff --git a/activerecord/lib/active_record/base.rb
b/activerecord/lib/active_record/base.rb
index b2e058d..f132f7c 100644
--- a/activerecord/lib/active_record/base.rb +++
b/activerecord/lib/active_record/base.rb @@ -701,7 +701,8 @@ module
ActiveRecord #:nodoc:
# Returns an array of column names as strings.
def column_names
-
@column_names = columns.map { |column| column.name } -
# @column_names ||= columns.map { |column| column.name }end
after that all columsn would be fetched,
I think it is a performance issue,
but I haven't another solution this time
