Admin console error

Using Django Mystery Errors
1

this is my models code

class Services(models.Model):
    title = models.CharField(max_length=100, verbose_name="title")
    title_en = models.CharField(max_length=100, verbose_name="title_en")


    class Meta:
        ordering = ['title']
        verbose_name = "services"

    def __str__(self):
        return self.title

and i add new rows

class Services(models.Model):
    title = models.CharField(max_length=100, verbose_name="title")
    title_en = models.CharField(max_length=100, verbose_name="title_en")
    title_head = models.CharField(max_length=100, verbose_name="title_head")
    title_de = models.CharField(max_length=100, verbose_name="title_de")
    class_icon = models.CharField(max_length=100, verbose_name="class_icon")

    class Meta:
        ordering = ['title']
        verbose_name = "services"

    def __str__(self):
        return self.title

In the first case, the admin was working fine, but when I added three new lines, it gives this error

…

It means that it cannot create new codes in the console, please help

After adding the new fields, did you do a makemigrations and migrate to update the database?

Hello, yes sir, I did these things

Please show the output of a showmigrations command. Then post the contents of the migration file that is to add the fields to that model.

Side note: When posting errors, please post the error message and traceback from the runserver console, not the error messages posted in the browser.

I think the database has a problem that it cannot add new lines after creating a new line? Your opinion is respected

Because it gives this error in the admin console
With this form in the browser

Please post the output of showmigrations (not makemigrations or migrate) and the content of the file in your apps migrations directory that has the migration information for this model for adding the files.

This is just the last line, we would need to see the complete traceback.

Also, please post the INSTALLED_APPS section of your settings.py file.
