create one-to-many relationship with campaigns module in sugarcrm - php

Question

How can i create one-to-many relationship with my custom module. And add subpanel to Campaign module
Campaign vardefs
$dictionary["Campaign"]["fields"]["costs"] =
array (
'name' => 'costs',
'type' => 'link',
'relationship' => 'campaign_costs',
'module'=>'Costs',
'bean_name'=>'Costs',
'source'=>'non-db',
'vname'=>'LBL_AUCTIONS',
);
$dictionary['Campaign']['relationships']['campaign_costs'] =
array (
'lhs_module'=> 'Campaigns',
'lhs_table'=> 'campaigns',
'lhs_key' => 'id',
'rhs_module'=> 'Costs',
'rhs_table'=> 'cots',
'rhs_key' => 'campaign_id',
'relationship_type'=>'one-to-many'
);
layout_defs properties
$layout_defs["Campaigns"]["subpanel_setup"]["campaign_costs"] = array (
'order' => 2,
'module' => 'Costs',
'subpanel_name' => 'default',
'sort_order' => 'desc',
'sort_by' => 'date_entered',
'title_key' => 'LBL_SUBPANEL_COSTS',
'get_subpanel_data' => 'costs', //имя поля link
'top_buttons' =>
array (
0 =>
array (
'widget_class' => 'SubPanelTopButtonQuickCreate',
),
1 =>
array (
'widget_class' => 'SubPanelTopSelectButton',
'mode' => 'MultiSelect',
),
),
);
Custom module vardefs
$dictionary['Costs']['fields']['campaign_id'] =
array (
'required' => false,
'name' => 'campaign_id',
'vname' => '',
'type' => 'id',
'massupdate' => 0,
'importable' => 'true',
'audited' => 0,
'len' => 36,
);
$dictionary['Costs']['fields']['campaign_name'] =
array (
'required' => false,
'source' => 'non-db',
'name' => 'campaign_name',
'vname' => 'LBL_CAMPAIGN_NAME',
'type' => 'relate',
'massupdate' => 0,
'comments' => '',
'help' => '',
'audited' => 1,
'len' => '100',
'id_name' => 'campaign_id',
'ext2' => 'Campaigns',
'module' => 'Campaigns',
'rname' => 'name',
'studio' => 'visible',
);
The relationship is added, but subpanel doesn't appear at campaigns module.

Answer 1

In your $dictionary["Campaign"]["fields"]["costs"], change bean_name from Costs to Cost.
I take it you have enabled the subpanel in the admin-menu? (index.php?module=Administration&action=ConfigureTabs)
Does your error-logs say anything?
