jpa - How to use @Where in Hibernate -

-

searched few hours, i'm stuck in learning curve playframework jpa. i'm building sample website posts can made. these posts can have states:

  • postdraft (post draft, not publish)
  • postpublished (post can published)

these states stored in seperate table. obviously, draft state posts should not visible yet.

so have these classes:

  • page class (getting page information table, 1 page can have multiple posts)
  • posts class (posts can in draft , published)

in page class have:

@column(name="posts_ref") @where(clause="postpublished") private list<posts> userposts;

but not working! so, how can specifify clause, load posts in published state without using jpql??

thanks!

update: 2011-10-11

table: posts columns: - id - title - state_ref (reference id of states table) - content

table: states columns: - id - statename

so want like:

select *  posts inner join states on posts.state_ref = states.id states.statename = 'postpublished'

update 2011-10-13

this current modification, in page class: not work either.

/** link states */ @joincolumn(name = "states_ref") @onetoone @where(clause = "states.statename = 'postpublished'") public mystate state;

update 2012-02-13 emt's answer worked me after all.

try like:

@column(name="posts_ref") @where(clause="state='postpublished'") private list<posts> userposts;

or 

@column(name="posts_ref") @where(clause="postpublished=true") private list<posts> userposts;

depending on status field type on post entity.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
