Nikita Timofeev reassigned CAY-2332:
------------------------------------
Assignee: Nikita Timofeev
> Property API: unable to use eq() and in() methods for toMany relationships
> --------------------------------------------------------------------------
>
> Key: CAY-2332
> URL: https://issues.apache.org/jira/browse/CAY-2332
> Project: Cayenne
> Issue Type: Bug
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Priority: Major
> Fix For: 4.2.M1
>
>
> Following code won't compile as {{eq()}} (as well as {{in()}}) method require
> {{List<Paintings>}} or other Property<> in this case, but everything else
> down the stack will correctly translate and execute this query and return
> correct result (I've checked this by simply allowing {{Object}} as argument
> in {{eq()}})
> {code}
> Painting painting =
> ObjectSelect.query(Painting.class).selectFirst(context);
> Artist artist = ObjectSelect.query(Artist.class)
> .where(Artist.PAINTING_ARRAY.eq(painting))
> .selectFirst(context);
> {code}
> Generated SQL:
> {code:sql}
> SELECT DISTINCT t0.ARTIST_NAME, t0.DATE_OF_BIRTH, t0.ARTIST_ID
> FROM ARTIST t0
> JOIN PAINTING t1 ON (t0.ARTIST_ID = t1.ARTIST_ID)
> WHERE t1.PAINTING_ID = ?
> LIMIT 1 OFFSET 0
> [bind: 1->PAINTING_ID:1]
> {code}
> Workaround can be parsing expression from string:
> {{.where(ExpressionFactory.exp("paintingArray = $p", painting))}}
