Please do not use float when dealing with currency fields, you are going to get all sort of strange issues, use decimal instead.

I've got this error " 'WSGIRequest' object has no attribute 'User' " . Does anybody here help me?

[@technoinfoworldwide2329]

you have validate in amount filed (it cant be empty) , but if we mix number and text like '123text' in amount field then it throws error, how to validate the amount filed for this?

[@crycetruly]

in the validation, you can use the isdecimal function and return an error when the amount contains a string characters before you save to db. you can about the example usage here www.w3schools.com/python/ref_string_isdecimal.asp

[@technoinfoworldwide2329]

@@crycetruly why u didn't use form.py for creating add-expense?it would be might easier for creating and validating
