select with alias tablenames broken
Reported by Martin Bosner | June 3rd, 2008 @ 02:57 PM
This worked before i upgraded to rails 2.1 (from 1.2.6) using mysql:
Model.find(:all,:conditions=>"1",:joins=>"as alias left join model2 as alias2 on alias.id = alias2.line_id")
To get it working you need to remove the alias or insert a custom select option:
Model.find(:all,select=>"*",:conditions=>"1",:joins=>"as alias left join model2 as alias2 on alias.id = alias2.line_id")
It seems that the later rails version add the default model tablename to the query e.g.:
select original_table_name.* from ...
That does not work because it needs the alias in the statement.
Is that a bug or a feature?

- State changed from “new” to “wontfix”
- Tag cleared.
I believe this is a feature, we wouldn't want joins to mask any attribute without explicit user approval. For example if you join multiple tables and select "*" then it becomes unclear which table's "id" attribute should be returned.
I'll close this for now, until convincing arguments are given for why this should be changed.
