search for: quoted_table_name

...efficient than storing a string like "SomeActiveRecordModel" over and over again. Looking in the association proxy classes for has_one and has_many, I see: def construct_sql case when @reflection.options[:as] @finder_sql = "#{@reflection.quoted_table_name}.#{@reflection.options[:as]}_id = #{@owner.quoted_id} AND " + "#{@reflection.quoted_table_name}.#{@reflection.options[:as]}_type = #{@owner.class.quote_value(@owner.class.base_class.name.to_s)}" else @finder_sql = "#{@reflection.quoted_table_name}.#...

I think Rails 2.1 introduced a bug when eager loading of associations with Oracle. In 2.1 ActiveRecord loads the included table with a big ''IN'' query: ''where association.id in (1, 2, 3, 4...)''. The problem is that Oracle has a hard limit of 1000 values in an IN clause. I get this error: ''OCIError: ORA-01795: maximum number of expressions in a list

...ELECT `users`.* FROM `users`" These back ticks on column names are mysql specific and are invalid for postgresql, so it throws an error. Does anyone know how to fully clear out whatever it is that is caching this sql being generated?? I searched through the source and was able to unset @quoted_table_name on the user model, this regenerated the table name properly, however the query now looks like: User.scoped.to_sql #=> "SELECT \"users\".* FROM `users`" Still not perfect. And I also don''t want to have to go through each model and unset a bunch of vars....

I have a basic model class TestTime with no customization. class TestTime < ActiveRecord::Base end I would like to pass the following SQL fragment as part of an AR save call to TestTime objects. How and where would I do this in the model? "set c_time=current_time" (current_time is an SQL method, not a variable). -- Posted via http://www.ruby-forum.com/.

Hi all, I''m running Rails on top of a Mongrel cluster. I have several model classes that are going to have so many records it is not feasible to keep them all in the same table. So I''ve split out the records into many different tables, each with its own suffix which corresponds to the id of the model to which all records in that particular table belong. For example,

I''ve loaded (and updated) thousands of these MeteredUsage records. In the middle of a run, I suddenly get: ActiveRecord::StatementInvalid: Mysql::Error: Unknown column ''id'' in ''where clause'': UPDATE `metered_usages` SET `cost` = 12603.46 WHERE `id` = NULL I can''t see anything that''s different about this particular record compared to

Hi, Why does ActiveRecord allow perception of success when updating an ID, however it doesn''t really work(i.e. no change in database)? Here''s an example. The update of "id" versus update of a non-existent attribute. ?> ai = AccountItem.find(:first) => #<AccountItem id: 1, account_id: 1, date: "2009-01-11", amount:
