Hello all.

I'm looking to implement quotas that are given to individual users at the group level. I'm hoping someone would have some insight into the intricacies of this task.

My initial thoughts:

Create a DataObjectDecorator to extend the Group class
- Add a UserQuota field
- Add a userQuota() method

Create a DataObjectDecorator to extend the File class
- Add a CreatedBy field

Create a DataObjectDecorator to extend the Member class
-Add a withinQuota() method

My questions:
Will an Extension to the File class be inherited by other classes? Namely the Image class?
How can I set the CreatedBy field to the current user when files are uploaded?
Additionally, file uploads will need to check the member's withinQuota() method, how can this be accomplished?
Inside the withinQuota(), I will need to pull all Files owned by that user, how should this be done?

Thank you in advance for any insight you can provide.

Yes I believe it should be as long as no methods / field names clash with ones in Image.

How can I set the CreatedBy field to the current user when files are uploaded?

Files already have a OwnerID field which stores the value of who uploaded the file. I'm guessing that is the same as want you want to do with CreatedBy so you probably don't need to add that field

Additionally, file uploads will need to check the member's withinQuota() method, how can this be accomplished?

You can set limits on a per filefield basis by setting setAllowedMaxFileSize(). Not completely sure how to set it globally, there must be a way to do so but I can't seem to find it. Using setAllowedMaxFileSize() however you could set it like

$field->setAllowedMaxFileSize($member->withinQuota);

Inside the withinQuota(), I will need to pull all Files owned by that user, how should this be done?

Well because File has a OwnerID you can run a simple DataObject::get('File', "OwnerID = '$this->ID'"); which will return a set of files for that owner.
