python - Django Datetime Issue -


what trying isn't difficult, isn't working. cannot see error is. in abstract user model have is_donator method not work.

    @property  def is_donator(self):     if(self.donator >= datetime.now()):         return true     else:         return false

some reason not return anything, looks alright me though, ideas?

you have 2 related issues. first using wrong comparison.

if(self.donator >= datetime.now()):

this means donor must become donor @ point in future.

change 

if(self.donator <= datetime.now()):

this ensure became donor in past.

the other issue have using auto_now:

automatically set field every time object saved. useful “last-modified” timestamps. note current date used; it’s not default value can override.

this, then, relates first issue. every time user field updated - if don't explicitly set field - defaults now.

update based on comments: checking if donator not null , ensure exists. if doesn't exist, determine logic, though if doesn't exist, user isn't donator. can return false in except block. block pretty verbose, shows explicitly happening.

def is_donator(self):     try:         if self.donator:      # checking self.donator not null             if(self.donator >= datetime.now()):                 return true             else:                 return false           else:             # return false?   # runs if self.donator null     except nameerror:         # (or 'pass', because self.donator value doesn't exist)
