in DownloadGroup entity I have this:
$metadata->mapManyToOne(array( 'fieldName' => 'product',
'targetEntity' => 'Entities\\Product',
'inversedBy' => 'dlGroups',
'joinColumns' => array( 0 => array( 'name'
=> 'id',
'referencedColumnName' => 'download_group',
'nullable' => true,
'columnDefinition' => NULL,
), )
));
and in Product entity this:
$metadata->mapOneToMany(array( 'fieldName' => 'dlGroups',
'targetEntity' => 'Entities\\DownloadGroup',
'mappedBy' => 'product',
'joinColumns' => array( 0 => array( 'name'
=> 'download_group',
'referencedColumnName' => 'id',
'nullable' => true,
'columnDefinition' => NULL,
), )
));
In DownloadGroup there are only two rows: id, groupName
groupName might be something like: 'Pro', 'Basic' etc.
then assign one or several product to groups as Pro, Basic etc.
May be there is no product as Basic and user might want to delete this
groupName, then I am getting this Notice message. How to avoid it? or am I
doing something wrong?
