Transaction Attribute + Validation

[Paul Hinett]

Hi,

 

What is the recommended approach for server side validation and the transaction attribute?

 

At the moment I am checking my ModelState for any errors, if any were found then I rollback the transaction and return them back to the entry form.

 

Is there not a more automated way to do this other than having to rollback the transaction manually each time?

I just changed Transaction attribute so it rollback on ModelError, if you define the attribute like this

[Transaction(RollbackOnModelStateError=true)]

you can check it here

I'll do a pull request with this patch.

Hi Rafael,

Although I do all the validation and transaction manipulation (begin,
commit, rollback) in ApplicationServices, I was wondering if it still
be ok to decorate Actions with
[Transaction(RollbackOnModelStateError=true)] as well, probably just
incase if I miss rollback logic in ApplicationServices ?

Hi Nabeel,

Yes you can. 

TransactionAttribute will always check if currentTransaction.IsActive before trying to commit/rollback.
