Your mistake is using the datetime module instead of the date module   You meant to do this  from datetime import date date   models DateField    quot Date quot    default date today   If you only want to capture the current date the proper way to handle this is to use the auto now add parameter  date   models DateField    quot Date quot    auto now add True   However  the modelfield docs clearly state that auto now add and auto now will always use the current date and are not a default value that you can override

I think a better way to solve this would be to use the datetime callable   from datetime import datetime  date   models DateField default datetime now    Note that no parenthesis were used  If you used parenthesis you would invoke the now   function just once  when the model is created   Instead  you pass the callable as an argument  thus being invoked everytime an instance of the model is created   Credit to Django Musings  I ve used it and works fine

You could also use lambda  Useful if you re using django utils timezone now  date   models DateField    Date    default lambda  now   date

This is why you should always import the base datetime module  import datetime  rather than the datetime class within that module  from datetime import datetime    The other mistake you have made is to actually call the function in the default  with the     This means that all models will get the date at the time the class is first defined - so if your server stays up for days or weeks without restarting Apache  all elements will get same the initial date   So the field should be   import datetime date   models DateField    Date    default datetime date today
