php - Multiple Associations to the Same Model in CakePHP 3 -

-

i using cakephp version 3.x.

when query messagestable want users data the sender , receiver of message. have done many times in cakephp 2 cant figure out why isn't working in version 3.x.

i have userstable , messagestable.

userstable

$this->hasmany('messages');

messagestable

$this->belongsto('users', [     'foreignkey' => 'sender_id',     'propertyname' => 'sender', ]); $this->belongsto('users', [     'foreignkey' => 'user_id',     'propertyname' => 'receiver' ]);

this query using

$messages = $this->messages->find()         ->where(['messages.user_id' => $this->auth->user('id')])         ->orwhere(['messages.sender_id' => $this->auth->user('id')])         ->order(['messages.created' => 'desc'])         ->contain([             'users.pictures',         ]);

i getting receiver data not sender data well. appreciated

your associations wrong. if using same model multiple associations need use different aliases , classname property (just in cakephp 2):-

$this->belongsto('sender', [     'classname' => 'users',     'foreignkey' => 'sender_id',     'propertyname' => 'sender', ]); $this->belongsto('receiver', [     'classname' => 'users',     'foreignkey' => 'user_id',     'propertyname' => 'receiver' ]);

this described in docs.

in example code receiver overwriting association user see receiver model in results.

your query needs like:-

$messages = $this->messages->find()     ->where(['messages.user_id' => $this->auth->user('id')])     ->orwhere(['messages.sender_id' => $this->auth->user('id')])     ->order(['messages.created' => 'desc'])     ->contain([         'receivers' => ['pictures'],         'senders' => ['pictures']     ]);

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
