[!CAUTION]

Found issue during pip packag installation from requirements.txt

• You cannot use query inside model, it will cause issue at first setup because there are no item in database.
• Instead change your model columns default vale
• This goes for all models, you can remove query becuase already using ForeighKey field.

class Mythology(models.Model):   
     # retrieve the category object representing 'Education' from the Categories model
-    education_category_obj = Categories.objects.get(category='Education')
     # retrieve the subcategory object representing 'Mythology' from the Subcategories model
-    mythology_subcategory_obj = Subcategories.objects.get(subcategory='Mythology')

-    category = models.ForeignKey(Categories, on_delete=models.SET_DEFAULT, default=education_category_obj.pk)   
-    subcategory = models.ForeignKey(Subcategories, on_delete=models.CASCADE, default=mythology_subcategory_obj.pk) 
     # - providing further control over the default value
+   category = models.ForeignKey(Categories, on_delete=models.CASCADE)
+   subcategory = models.ForeignKey(Subcategories, on_delete=models.CASCADE)

@deviserops Thanks, I'll have a look

@deviserops I would also like to follow up on your recommendation for models.py. Does

• category = models.ForeignKey(Categories, on_delete=models.CASCADE)
• subcategory = models.ForeignKey(Subcategories, on_delete=models.CASCADE) mean that the default values will have to be selected on the database instead of it automatically being selected?
