Nested CatalogPages

[thezenmonkey]

I have the following two catalog pages

• Artwork
• Artist

I'd love to give the client the ability to add/modify Artwork from it's own CatalogPageAdmin or from a Gridfield on Artist. However, when I add CatalogPageGridFieldDetailForm to either a RecordEditor or RelationEditor on Artist it always saves the Artwork to the first Artist and boots me back to teh ArtistAdmin when publishing the Artwork

Hey @thezenmonkey
We've used this for nested catalog pages previously and have had to make some changes to the way which we instantiate the gridfield to allow for the ParentID to be passed through. Do you have an example of this we can use to go through and work out the best way to make this work natively?

[thezenmonkey]

I worked through something like this a while back on frankmullenger/silverstripe-gallery It required adding the ParentID to the constructor Pull Request.

I don't know enough about GridField currently, and I swamped trying to get that site to launch.

I can launch without, and circle back after and try and help tackle it.

The basic version of it is:
ArtistHolder is the Parent Page for Artist while the Artist Pages are the Parent Pages for Artwork. I have seperate CatalogPageAdmins set up for Artist and Artwork (ArtworkAdmin and ArtistAdmin).

I can post my (ugly) code if it will help.

Please post your ugly code - we can try get it working.

We've added the ParentID in the model constructor previously by overloading the GridField instantiation like the below:

        $gridField = GridField::create(
            'Artwork',
            'Artwork Page',
            Artwork::get()->filter('ParentID', $this->ID),
            $gridFieldConfig = CatalogDataObjectGridFieldDetailForm::create()
        );

        $gridFieldConfig->setItemRequestClass('CatalogPageGridFieldDetailForm_ItemRequest');

        if ($this->exists()) {
            $model = new Artwork();
            $model->ParentID = $this->ID;
            $gridFieldConfig->setFields($model->getCMSFields());
        }

Then on Artwork's getCMSFields()

        $fields->addFieldsToTab("Root.Main", new HiddenField("ParentID", "ParentID",$this->ParentID), "Content");

@thezenmonkey are you still having issues with this?

[thezenmonkey]

Sorry for the silance. I abandonded that implementation and changed the child object t DataObject instead of a Page

[stevie-mayhew]

@thezenmonkey thats okay :) I think this is still an issue which needs to be solved so will leave this one open
