# T1 - Exceptions
In general keep exceptions in views, not in models. 
Put exceptions in models just when very necessary like to make process atomic or multiples tasks, 
even in this case think if is not better split the method in multiple methos and treat exception in each method

# T2 - Always try to name the relationships

# T3 - Concentrate business logic into models methods and Managers

# T4 - Always help_text
