Hi,
I am getting an error when trying to create a GridField.

GET http://localhost/sspass/admin/pages/edit/show/36
	
500 Error at line 675 of /home/USERNAME/www/sspass/framework/core/Object.php 


ERROR [User Error]: Uncaught Exception: Object->__call(): the method 'sspassgroups' does not exist on 'SspassPage'
IN GET /sspass/admin/pages/edit/show/36
Line 675 in /home/USERNAME/www/sspass/framework/core/Object.php

I have 2 DataObject

SspassAccount.php
----------------------------------------------

class SspassAccount extends DataObject{
    
    public static $db = array(
        'Name'      => 'Varchar(255)',
        'Content' => 'HTMLText'
    );
    public static $has_one = array(
        'SspassPage' => 'SspassPage',
        'SspassGroup' => 'SspassGroup'
    );
    
    public static $singular_name = 'SspassAccount';
    public static $plural_name = 'SspassAccounts';
    
    public function getCMSFields() {
        parent::getCMSFields();
        
        $fields = new FieldList(
              new TextField( 'Name' , 'Account Name') ,
              new TextareaField( 'Content' , 'Content')  
        );
        return $fields;
    }
}

SspassGroup.php
----------------------------------------------

class SspassGroup extends DataObject{
    
    public static $db = array(
        'Name' => 'Varchar(255)'
    );

    public static $has_meny = array(
        'SspassAccounts' => 'SspassAccount'
    );
    
    public static $has_one = array(
        'SspassPage' => 'SspassPage'
    );
    
    static $singular_name = 'SspassGroup';
    static $plural_name = 'SspassGroups';
    
    public function getCMSFields() {
        parent::getCMSFields();
        
        $fields = new FieldList(
              new TextField( 'Name' , 'Name')  
        );
        return $fields;
    }
}

and the page

SspassPage.php
----------------------------------------------

class SspassPage  extends Page{

	public static $db = array(
            
	);

	public static $has_one = array(
	);
        
        public static $has_meny = array(
            'SspassAccounts' => 'SspassAccount',
            'SspassGroups' => 'SspassGroup'
            
        );
        public function getCMSFields(){
            $fields = parent::getCMSFields();

            $config = GridFieldConfig_RelationEditor::create();    
            $config->getComponentByType('GridFieldDataColumns')->setDisplayFields(array(
                'Name' => 'Name'
            ));
            // Create a gridfield to hold the student relationship   
            $groupsField = new GridField(
                'SspassGroups', 
                'SspassGroups', 
                $this->SspassGroups(), // <--------- ERROR [User Error]: Uncaught Exception: Object->__call(): the method 'sspassgroups' does not exist on 'SspassPage'
                $config
            );      


            $fields->addFieldToTab( 'Root.Groups', $groupsField);   
      

        return $fields;
	}
}

The bussiness logic:
SspassPage should have 2 tabs, one for adding accounts and one for edding groups, one groupe has meny accounts

Am I missing something?

Small typo: $has_meny should be $has_many in classes SspassGroup and SspassPage.

Btw hope we're not supposed to take your eh... 'greeting' seriously :)

Well I feel embarrassed now!! Thanks a lot, I would not see that for a long time :D.

I need to get out more!

Thanks mate!!

PS. Dont take anything on the Internet seriously, life is too short!
