Hello,

I'd like to create a grid that will allow me to add some photos with names to general configuration (Settings Tab).
So I followed many tutorials and in every of them they use the schema that does not work for me.

I get Fatal error: Call to undefined method GostcompSiteConfig::CooperativesLogoImages() in C:\wamp\www\gostcomp\mysite\code\GostcompSiteConfig.php on line 27. when I try to get to /admin/settings.
Dev/Build success without errors...

Below I show the GostcompSiteConfig.php that looks like many others tutorials about gridfields...

class GostcompSiteConfig extends DataExtension {     
 
    public static $has_many = array(
        'CooperativesLogoImages' => 'CooperativePhoto',		
    );

    public static $db = array(			
        //'FacebookURL' => "Varchar(250)",
        //'VimeoURL' => "Varchar(250)",				
    );

    public function updateCMSFields(FieldList $fields) {
        //$fields->addFieldToTab("Root.CooperativesLogos", new UploadField("CooperativesLogoImages", _t('GostcompSiteConfig.LogosForYourCooperatives', "Zdjęcia (loga) partnerów")));
        
        $gridFieldConfig = GridFieldConfig_RelationEditor::create()->addComponents(
            new GridFieldDeleteAction('unlinkrelation')
        );
        
        $fields->addFieldToTab("Root.CooperativesLogos", new GridField("CooperativesLogoImages", "CooperativePhoto", $this->CooperativesLogoImages(), $gridFieldConfig));
        //$fields->addFieldToTab("Root.Main", new TextField("FacebookURL", "Enter the full URL of your Facebook page"));	 
        //$fields->addFieldToTab("Root.Main", new TextField("VimeoURL", "Enter the full URL of your Vimeo page"));	
    }
}

class CooperativePhoto extends DataObject
{
    public static $db = array(
        'Name' => 'Varchar',
    );
    
    public static $has_one = array(        
        'Photo' => 'Image',
        'SiteConfig' => 'SiteConfig'
    );
    
    // Summary fields 
    public static $summary_fields = array('Thumbnail'=>'Thumbnail','Name'=>'Name');
    public function getThumbnail()
    { 
        return $this->Image()->CMSThumbnail(); 
    }
    
    public function getCMSFields_forPopup() 
    { 
        // Profile picture field
        $thumbField = new UploadField('Photo', 'Photo (transparent background suggested)');
        $thumbField->allowedExtensions = array('png');

        // Name, Description and Website fields
        return new FieldList(
            new TextField('Name', 'Name'),
            //new TextareaField('Description', 'Contact description'),
            //new TextField('Website', 'Website URL (including http://)'),
            $thumbField
        );
    }
}

Finally I add this extension to SiteConfig in _config.php file

Object::add_extension('SiteConfig', 'GostcompSiteConfig');

Hi Sebastiankozub,

Can you post up both your GostcompSiteConfig.php and CooperativePhoto.php files?

However before doing that, try a /dev/build/?flush=1

I cant see much wrong with your code, however if that is your entire GostSiteConfig.php file It's missing the opening "<?php" tag.

EDIT: I think I've found your issue. Your extension needs to be the following:

_config.php

SiteConfig::add_extension('GostcompSiteConfig');

Nothing of the mentioned solutions:
1. dev/build?flush=1 works perfect - no error
2. <?php is present
3. When change updateCMSfields to getCMSfields and return them do not get Fatal Error but then I cannot see any new tab in settings.

I have no CooperativePhoto.php file, CooperativePhoto class is defined in GostcompSiteConfig.php
I think you are smart and help me :(

Hi Sebastiankozub,

I have edited my previous post:

EDIT: I think I've found your issue. Your extension needs to be the following:

_config.php

SiteConfig::add_extension('GostcompSiteConfig');

Then dev/build?flush=1

No change, still the same fatal error when usping updateCMSfields and no change in Settings tab when using getCMSfields in class GostcompSiteConfig.

I think the problem is that framework cannot generate list of CooperativesLogoImages and then there is no $this->CooperativesLogoImages() function in SiteConfig.
1. Maybe this is caused by Image (without relation) in CooperativesPhoto?
2. Maybe this is cause by that I use DataExtension?
3. Maybe this caused by that it is not the SiteConfig extending, but the class is added as extension?

I have lack of knowledge in SS framework. Maybe someone the ideas above will give someone some "eureka" :)

SOLUTION

$fields->addFieldToTab("Root.CooperativesLogos", new GridField("CooperativesLogoImages", "CooperativePhoto", new DataList('CooperativePhoto'), $gridFieldConfig));
