You just join the CT table.

creates two joins instead of 1.

That'd select the content type (which you can of course already do), not the final object

if you stopped there, of course not. you go one further and join the final object.

Except you can't join an unkown table in SQL

you know the table by the CT.

Yes, but you can't do SELECT * FROM my_table JOIN content_type ON content_type.id = my_type.content_type JOIN content_type.db_table ON somethign;

well no. But you wouldn't. Maybe a select_related would trigger some extra() work.

to keep out of internals.

I don't follow, the query you're suggesting isn't possible at the SQL level

I'll have to prepare a snippet.

Hi guys. A spriner from last Saturday has posted a patch for #12627 and we would like to ask for review aout the sstrategy used to fix the issue.

cramm: why not just have admin validation disallow ModelAdmin with no fields?

Eh, there's nothing tidy enough that would ever be accepted into the ORM

Alex_Gaynor: Problems is that the ticket report two issues together. The readonly_fields one is admin-specific, and the all-model-field-with-editable=False isn't

cramm: perhaps that should be form level validation then? at the end of forms.Form.__init__ have assert self.fields, "There must be fields on a form"

yeah, I suppose it could only be done with two queries and I'm not sure how the second part would happen. It would essentially be an ugly find-and-replace of the first statement.

Alex_Gaynor: Thanks for your fedback. The PyCamp is ending now, they plan keep working on it

jezdez: ^ :)

Could anyone here review the unit test I made in http://code.djangoproject.com/ticket/12822 ? I'm not 100% sure what's going on but looks like I found another regression in 1.2 when playing with aggregation

help needed with something simple - how to list subselect model linked by foreign key for each object parent please?
