		41	+STYLE RULES
		42	+===========
		43	+https://simpleisbetterthancomplex.com/tips/2018/02/10/django-tip-22-designing-better-models.html
		44	+https://steelkiwi.com/blog/best-practices-working-django-models-python/
		45	+
		46	+- Model name => singular
		47	+ Call it Company instead of Companies.
		48	+ A model definition is the representation of a single object (the object in this example is a company),
		49	+ and not a collection of companies
		50	+ The model definition is a class, so always use CapWords convention (no underscores)
		51	+ E.g. User, Permission, ContentType, etc.
		52	+
		53	+- For the model’s attributes use snake_case.
		54	+ E.g. first_name, last_name, etc
		55	+
		56	+- Blank and Null Fields (https://simpleisbetterthancomplex.com/tips/2016/07/25/django-tip-8-blank-or-null.html)
		57	+ - Null: It is database-related. Defines if a given database column will accept null values or not.
		58	+ - Blank: It is validation-related. It will be used during forms validation, when calling form.is_valid().
		59	+ Do not use null=True for text-based fields that are optional.
		60	+ Otherwise, you will end up having two possible values for “no data”, that is: None and an empty string.
		61	+ Having two possible values for “no data” is redundant.
		62	+ The Django convention is to use the empty string, not NULL.
		63	+ Example:
		64	+ # The default values of `null` and `blank` are `False`.
		65	+ class Person(models.Model):
		66	+ name = models.CharField(max_length=255) # Mandatory
		67	+ bio = models.TextField(max_length=500, blank=True) # Optional (don't put null=True)
		68	+ birth_date = models.DateField(null=True, blank=True) # Optional (here you may add null=True)
		69	+ The default values of null and blank are False.
		70	+ Special case, when you need to accept NULL values for a BooleanField, use NullBooleanField instead.
		71	+
		72	+- Choices : you can use Choices from the model_utils library. Take model Article, for instance:
		73	+ from model_utils import Choices
		74	+ class Article(models.Model):
		75	+ STATUSES = Choices(
		76	+ (0, 'draft', _('draft')),
		77	+ (1, 'published', _('published')) )
		78	+ status = models.IntegerField(choices=STATUSES, default=STATUSES.draft)
		79	+
		80	+- Reverse Relationships
		81	+
		82	+ - related_name :
		83	+ Rule of thumb: if you are not sure what would be the related_name,
		84	+ use the plural of the model holding the ForeignKey.
		85	+ ex:
		86	+ class Company:
		87	+ name = models.CharField(max_length=30)
		88	+ class Employee:
		89	+ first_name = models.CharField(max_length=30)
		90	+ last_name = models.CharField(max_length=30)
		91	+ company = models.ForeignKey(Company, on_delete=models.CASCADE, related_name='employees')
		92	+ usage:
		93	+ google = Company.objects.get(name='Google')
		94	+ google.employees.all()
		95	+ You can also use the reverse relationship to modify the company field on the Employee instances:
		96	+ vitor = Employee.objects.get(first_name='Vitor')
		97	+ google = Company.objects.get(name='Google')
		98	+ google.employees.add(vitor)
		99	+
		100	+ - related_query_name :
		101	+ This kind of relationship also applies to query filters.
		102	+ For example, if I wanted to list all companies that employs people named ‘Vitor’, I could do the following:
		103	+ companies = Company.objects.filter(employee__first_name='Vitor')
		104	+ If you want to customize the name of this relationship, here is how we do it:
		105	+ class Employee:
		106	+ first_name = models.CharField(max_length=30)
		107	+ last_name = models.CharField(max_length=30)
		108	+ company = models.ForeignKey(
		109	+ Company,
		110	+ on_delete=models.CASCADE,
		111	+ related_name='employees',
		112	+ related_query_name='person'
		113	+ )
		114	+ Then the usage would be:
		115	+ companies = Company.objects.filter(person__first_name='Vitor')
		116	+
		117	+ To use it consistently, related_name goes as plural and related_query_name goes as singular.
		118	+
