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 = 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 = 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.
