What is this error mean and what can I do

[Saeed Pooladzadeh]

Hi

This is my model:

from django.db import models

from django.conf import settings

# Create your models here.

class Smodel(models.Model):

    eid=models.IntegerField()

    elogin = models.CharField(max_length=8) 

    epassword= models.CharField(max_length=8) 

  

    elikeDay=models.IntegerField()

    efollowPerDay=models.IntegerField()

    

   

    #esession = models.TextField()

    class Meta:  

        db_table = "saeed"  

And I get this error:

OperationalError at /emp

Django Version:	2.2

You got this error because you didn't perform migrations to create the table in your database 

Run>> python manage.py makemigrations

It will create migration number under migrations. Then make sqlmigrations

>> python manage.py sqlmigration <name of your app>  <migration number> 

It will create sql scripts to create a table on your database, then make migrations

>>python manage.py migrate

You may skip sqlmigration and still table will be created but is the best practice to run it so that you can preview how table will look like.

Remeer to perform migrations each time you create or modify your models

Best Regards

Yes I think you should first do "makemigrations" and then run migrate
