there is a discussion about this 10 years ago …
abhishek
Yes but for me I was getting stuck in logic but now I got it I need to fetch the previous integer from db and need to give an single increment for that
abhishek
Like id it will increase
For empid it should start from 100
abhishek
Like that
Adzmely
id= autofield
empid = id + 100
abhishek
Ohh ok
Adzmely
u can add a save func in your model class , that take the value of self.id and set self.empid = self.id + 100
Adzmely
overide save method in order to set the empid value ..

overide save method in order to set the empid value ..
To be honest, it's bad practice to override save method, in his case better desicion to use signals
Adzmely
To be honest, it's bad practice to override save method, in his case better desicion to use signals
imho it is not a total overide , you just like injecting some extra things before the real “super” save
abhishek
Super save?
abhishek
Ok

Hello All,
is it a good idea to create different table (i.e model) to store 2 different type of users?
I want them to signup with different fields in form. I've created a custom user model.

With RESTful API
For creating rest API in Django, you should use Django Rest Framework

Suppose I have to use components of reacts then how should I do.
Mirco
Suppose I have to use components of reacts then how should I do.
2 projects:
1. React
2. Django with Rest framework as installed app
With Django you expose APIs
With React you will consume APIs by using axios for example

Plenty of mvcs have advantages and disadvantages. Django might not be the fastest or have the newest bells and whistles, but it's widely adopted, proven to support huge applications, and makes life very easy. So it should be right up there with any framework you consider 😃

Please i have reoccurring issues with my django model , migrations and database.
Summary, today i changed my default id to uuid and then after migration, i wanted to run migrate command but have been getting error (django.db.utils.IntegrityError: could not create unique index)
I know if i delete database table, the problem will be solved but i already have a lot of information
Please how can i solve the problem without dropping my table
👑 Dharmzeey
I have checked the internet, and tried several methods, but none worked
👑 Dharmzeey
And also, not only for uuid, in the past I have run into such error whereby I later end up deleting the migration and the table, but I don't want to delete the fable
It is even always worse in production

Hello All,
is it a good idea to create different table (i.e model) to store 2 different type of users?
I want them to signup with different fields in form. I've created a custom user model.
“..always use one, and only one Django model to handle the authentication.
You can still have multiple user types, but generally speaking it’s a bad idea to store authentication information across multiple models/tables.”
Good read for you https://simpleisbetterthancomplex.com/tutorial/2018/01/18/how-to-implement-multiple-user-types-with-django.html
How many different fields are you considering for those user types?
If it’s just a few, you can just add all fields to the same user model, with one field that differentiates them, and handle loading different fields using Django’s forms logic.
If it’s a lot, consider
1. Subclassing into 2 user types, or
2. Storing that different information as its own model/table
