Hi,In my models I’ve some FloatFields that must be > 0. I’m wondering what is the best way to check, at the model level (not form), that the values for these Fields are greater than 0? Browsing the documentation I’ve found the following three methods: * Add the MinValueValidator <https://docs.djangoproject.com/en/1.6/ref/validators/#minvaluevalidator> to each field. * Check them in the model.clean() method
I use the model's clean() method which is always called by the form. However, if you are not using forms you have to remember to call the clean method. Eg, in unit tests.
* Create a custom field that accept only floats > 0. And, if a choose the custom field, which FloatField’s method do I need to override to check that the value is > 0?
I don't use floats as a rule but I would probably use isinstance and possibly a range like > -0.000001 and < 0.000001 or whatever your app requires.
