Post is the name of our model. We can give it a different name (but we must avoid special characters and whitespace). Always start a class name with an uppercase letter. models.Model means that the Post is a Django Model, so Django knows that it should be saved in the database.

As you say, models is a package, that is, a set of classes / methods. For convenience, models and forms are imported only once and the classes they contain are used. Example: models.CharField, otherwise you would have to import the classes one by one (unnecessarily).
Model is a class to create entities in your database.

r/django on Reddit: ELI5: Django Models and Model Methods?
August 24, 2022 -
My understanding so far is, the Django models is used to create the actual columns for the database.
Once I have declared the columns. What is the methods that follow it ? The documentation says this:
Define custom methods on a model to add custom “row-level” functionality to your objects. Whereas Manager methods are intended to do “table-wide” things, model methods should act on a particular model instance.
This is a valuable technique for keeping business logic in one place – the model.
ELI5?
I'm trying to create a comments section using React JS, this is the model I have so far:
class Comment(models.Model):
show = models.CharField(max_length=25)
username = models.CharField(max_length=16)
comment = models.TextField(max_length=1000)
time_stamp = models.DateTimeField()
What kind of methods would be relevant?
Also, I understand that Django comes default with sqlite3. If I was to go into settings.py and change the database to MySQL, would my models create the columns in MySQL instead? And would the backend admin page login take me to the MySQL database?

What kind of methods would be relevant? Whichever ones you need. I know that sounds like a smartass answer, but you can make them up as you need them. If you don't need any yet, then you don't need any. We can explore this idea in a bit. First, let's talk about some commonly-used builtin model methods. Built-in model methods In terms of default model methods that you can override, here are the ones I commonly use with Django templates (while also keeping in mind that you're using React): get_absolute_url(): Typically used to navigate to an object's DetailView e.g. after saving a form for that object. You probably don't need this in React. save(): Any time you save a model, you may want to do some custom stuff to it. You may need this. __str__(): When called, this model gives a string representation of that object. e.g. in templates, it will be displayed when you call {{ your_object }}, or when you call str(your_object) in your view code. You may need this. Custom methods In terms of custom methods, it depends on what you would want to do. For example, let's say you wanted to make comments threaded (maybe you don't need this, it's just an example). You could make a ForeignKey that ties a comment to another comment. Here's an example of how to do that. Add this field to your model: class Comment(models.Model): parent = models.ForeignKey('your_app.Comment', null=True, on_delete=models.SET_NULL) So we've created a ForeignKey named parent, which allows you to link a comment to another comment. It links to your model, is optional (null=True), and will not be deleted if its parent is deleted (on_delete determines what happens to an object if all its related objects are deleted. Use models.CASCADE if you want it to be deleted when its parent is deleted). OK, now that we have nested comments, I have an idea for a custom method: View most recent replies to that comment! Here's a method: def recent_replies(self): return self.comment_set.order_by('-timestamp')[:5] Now when we call your_object.recent_replies() in your view code, it will return up to 5 child comments, with the most recent ones displayed first. Hooray! Make sure to run manage.py makemigrations and manage.py migrate after modifying your fields. The ORM is the same for different databases. To answer the last question, yes. The field declarations are the same no matter what database is used. Note that there are some fields that are only used in PostgreSQL (see here ), but you probably don't need them (PostgreSQL is a good choice for a database though FYI).

Defining custom methods depends if your application needs it . Even without custom methods simple CRUD will work just by using predefined methods. Try to work those predefined first till you get familiar, then if that doesn't satisfy what you need then create custom methods. https://docs.djangoproject.com/en/4.1/topics/db/queries/ Also, I understand that Django comes default with sqlite3. If I was to go into settings.py and change the database to MySQL, would my models create the columns in MySQL instead? And would the backend admin page login take me to the MySQL database? You need to run migrations first.then it will check what are the missing migrations on your new db and it will create those columns. Migrations only applies on the schema, that doesn't include the data from your old database. Based on your model. If its a comment section you need another field that represent the parent of a comment(post)

It means: make the Poll class inherit from the Model base class from the models module.

Do you know what inheritance is? I would start by looking at some examples:
http://parand.com/say/index.php/2009/04/20/python-simple-inheritance-example/
It is basically saying to use all the properties that the Model class has plus whatever you define on your class.
Good luck
in php that would be:
class Poll extends Model
{
var $question;
var $pub_date;
}
Model is a class that is in the models module in Django framework...
