Inheriting from ActiveRecord::Base with no DB table


I need to upload a CSV file in my application and I am trying to do so
with a sample I found googling around, which defines a model that
inherits from ActiveRecord::Base.

The problem I am having is that whenever an error occurs Rails
complains because there is no DB table behind the model, which I don't
need since there would be nothing to be stored in it.

I would like to be able to not have the table and also use
ActiveRecord::Errors capabilities since I would like to keep the look
and feel of the rest of the page when handling errors.

Is there a way of telling Rails that there is no table behind the
model? And if that is not possible, is there a way to instantiate an
ActiveRecord::Errros object inside the class without inheriting from
ActiveRecord::Base and make it work the same way as it usually does?



A few minutes googling gave me a plugin:

You will get all classes along with the validation classes from
ActiveRecord in this way. Besides you wont need any corresponding
table for this model.

I didnt try it out yet but hope you may find it usable.
Let me know if it worked for you. Then we would use it if necessary...

Thank you

Thanks Samiron,

I appreciate you spending your time to help me out. I spent quite a
bit of time googling myself but didn't come across this link. I was
hoping ActiveRecord itself would have something built in to it. I took
a look at attachment_fu but it was way overkill for what I need. I'll
also take a look at paperclip to see if that is also a good fit.

Thanks a lot! :slight_smile:
