Multiple ERAttachment Databases

Hi all,

I’m working on a project that needs to have a separate, independent ERAttachment setup. What I mean is that the project is already using ERAttachment for a few things, but now I have a need for all of ERAttachment’s functionality, only storing all the meta-data and even db-based attachments in a completely different database than where the existing attachments are stored.

I have done exactly this before by forking ERAttachment into a new "DaveAttachment" Framework. All the existing attachments worked using the stock ERAttachment framework, but the new attachments were managed by DaveAttachment, but that is long-term code management PITA.

I’m wondering if it would it be possible enable ERAttachment to use multiple data-stores by programmatically cloning the ERAttachment EOModel at startup and creating a new EOModel for each “data-store” with independent Entity names as configured by properties? 

If you only have one data-store (the current functionality) then ERAttachment would continue to work as-is, but if you specify multiple data-stores in the properties, that would trigger the programatic creation and loading of the additional models?

Does anyone see anything that I’m missing that would not allow this?

Thanks!

Dave
