Hello all,

How to give validation on a field which is not a database column. I mean
i am having a file field(upload_resume) in my views. So i want to give
validation on it that size should be less then 1mb. I tried
self.upload_resume and params[:upload_resume] but both are not working.

Are you trying to check the file size before or after the upload?

Hello Guys,
Thanks for your replies.

Yes i want to check the size of file before upload only. I mean first i
am checking that file had valid attributes or not. If it has then upload
it else dont.
Currenly i am doing this in controllers but for cleaner code i want to
do it in models with validations.

How are you checking the file attributes in the controller?

Just like as
if File.size(params[:upload_resume]) > 1mb
  redirect_to :back with some flash[:notice]
end

The only problem with this is that i am unable to retain the form values
after redirecting.

Is params[:upload_resume] a filename on the users PC? I am probably
showing my ignorance here, but how does the server know the size of a
file on the users PC? I hope you are not testing this by 'uploading'
from a PC which is actually also the server running the rails app, so
that the file is directly accessible from the rails app before it is
uploaded.
