In Turnkey, you upload and download the model to the MDrivenServer.

It is possible to accidentally push upload instead of download – can you get the old model back?

Yes, it is. Do this.

Log in to MDriven Portal to find the password to MDrivenServer:

Once you have the password in the clipboard, press the link “Visit MDrivenServer” marked in green above.

You will end up here:

Login with user a and the password from your clipboard.

You end up here:

Choose the Admin area – you end up here:

Choose Model Version Administration:

Choose slot A0 and select the last model which is the one you accidentally uploaded. Select it by clicking the green checkmark on the row – then delete it. If you now head back to MDrivenDesigner and choose "download model", you will get the last one in this list.

Eight models are automatically kept in this log.

If there are zero models in this list, the one you upload will recreate the database. If there is a model already when you upload, the database will be evolved (changed).

Update 2016-10-01

When you delete the current version of the model, the application is left in a state where no version is active. We must set the current version in the CurrentVersion-Combobox. To do this, we must first stop the application. After we set the version, we start the application again:

It seems reasonable that the application should be required to be in a stopped-state before we can delete the current model – I will add a change request for this.
