You can undergo any course and read any book you like. To master django (as any other software or platform) you will have to learn software architecture and databases anyway. And they are both separate themes.

Depends on your situation. Protip - using it for wrap db queris is a very bad idea.

can you give me an example of a property in a model?

Is it like an attribute we 'can't' define on the attibutes part because it would create a field in the database?

like, if you want a complex representation like what you do with __str__

can you give me an example of a property in a model?

Models.py file- Charfield, Textfield, Intfield These are properties

class xyz(models.ModelField): fullname=models.charfield(max_length=100)

class xyz(models.ModelField): fullname=models.charfield(max_length=100)

That looks like a field

That looks like a field

Yea... Character field

can you give me an example of a property in a model?

It's a bad design decision, imho, but it's an example for a good usage of properties in models. Lets say you have an eshop and you check whether an order was paid or not. You have the Payment model which has a boolean flag if there was verification by a payment system that money are received. But sometimes for some reasons such verification may lag for long time. But a client calls you back and says that he already paid his order and it's really displayed in the payment system's dashboard. So we can add manual_verified flag for the Payment. So instead of checking them both in our code we can add a property maybe_payed class Payment(models.Model): @property def maybe_payed(self): if self.verified or self.manual_verified: return True

Is it like an attribute we 'can't' define on the attibutes part because it would create a field in the database?

Not. It is when such attribute duplicate state or can be calculated.

like, if you want a complex representation like what you do with __str__

Model should not handle representation logic. It's about holding data.

Not. It is when such attribute duplicate state or can be calculated.

What do you mean by duplicate a state?

Models.py file- Charfield, Textfield, Intfield These are properties

These are descriptors. Yes, they are properties, but they handle much complex logic.

Hello guys, I transferred a template to Django and it is OK It only has one login that has a separate login and separate links and scripts The same css and js are separated Now should I introduce these links where I introduced my index link or Create a directory called Reference Login, for example, and drop it there. Or there is another way Which is more efficient and standard? Your mouth is hot.

Hello alex

#project hello every one i have a project that want to add new option to it . the backend is django is exist enyone for help me The method of cooperation is hourly. please come to pv.

What do you mean by duplicate a state?

I mean it would duplicate state if we define it as a field. Once again a bad example, but the one I can provide right now - phone numbers. Or names. Say we store a phone in our db like a string of numbers with any other characters truncated. Like 79998887776655. But for a user we want to represent it like +7(999)888-777-66-55. So instead of defining one more model field with that, we could make a property to make a userfriendly representation from the first one. Again, it is actually a bad design because neither model, nor db should be responsible for representing your data, but it's an example of handling duplication.

Why not define this on the str method?

Sorry, my english sucks ass -_-

Why not define this on the str method?

Because that would be a method without any arguments (except for self ofcourse)

And actually it should be a template filter of even a tag if you actually need much complex logic.

Why not define this on the str method?

Oh, you mean __str__? Because it's responsible for representing a model (in contex of django), but we want to represent only the field.

I see

Also, a representation limits further possible use of data

What? No. It's simply another layer of logic.

How to make ModelForm if one field is ForeignKey? The api passes the ‘code’ field to the Insurance model, not the Insurance object itself So I have to find Insurance by code and write it in Contract in the insurance_company FK-field https://dpaste.org/yUVT

I mean the __str__

You just use it when you print the value, usually you don't use it for further calculations

I'm trying to determine when to use a property, I think I got it

*To give userfriendly representation of an object.

I was using the __str__ not only to give a friendly representation but also to display a long representation with all the fields

Including, a complex representation of a flag

Basically, I was doing a lot of logic on __str__

In django templates are representation layer.
