Hallo,
I am just fighting with a problem on relations in Models.
I have moved from the conventions changing the primary key.
$this-\>setTable(‘accounts’);
$this-\>setDisplayField(‘name’);
$this-\>setPrimaryKey(‘account\_no’);
and
$this-\>hasMany(‘Costcenters’, [‘foreignKey’ =\> ‘account\_no’,]);
That works fine. The purpose is I have to avoid lots of new entries each new year. OK so far so good, but I need an additional relationship like:
```
$this->hasMany('Journals', ['foreignKey' => 'actAccount',]);
```
which is containing the id of the related account.
Can I have both? I read the cookbook/Table Objects several times but have not found the way.
Thanks in advance

you can add as many associations to your table as you like
```auto
$this->belongsTo('Projects', [
'foreignKey' => 'project_id',
'joinType' => 'INNER',
]);
$this->belongsTo('EasybillDocuments', [
'foreignKey' => 'easybill_document_id',
'joinType' => 'INNER',
]);
$this->belongsTo('ProjectDocumentTypes', [
'foreignKey' => 'project_document_type_id',
'joinType' => 'INNER',
]);
```
just put them underneath each other
