Django 1 11 delete all objects from a database table -   Entry objects all   delete       Entry being Model Name     Refer the Official Django documentation here as quoted below -  https   docs djangoproject com en 1 11 topics db queries  deleting-objects  Note that delete   is the only QuerySet method that is not exposed on a Manager itself  This is a safety mechanism to prevent you from accidentally requesting Entry objects delete    and deleting all the entries  If you do want to delete all the objects  then you have to explicitly request a complete query set   I myself tried the code snippet seen below within my somefilename py         for deleting model objects     from django db import connection     def del model 4 self           with connection schema editor   as schema editor              schema editor delete model model 4    and within my views py i have a view that simply renders a html page         def data del 4 request         obj   calc 2             obj del model 4         return render request   dc dash data del 4 html         it ended deleting all entries from - model    model 4   but now i get to see a Error screen within Admin console when i try to asceratin that all objects of model 4 have been deleted      ProgrammingError at  admin dc dash model 4  relation  dc dash model 4  does not exist LINE 1  SELECT COUNT    AS    count  FROM  dc dash model 4     Do consider that - if we do not go to the ADMIN Console and try and see objects of the model - which have been already deleted - the Django app works just as intended    django admin screencapture

If you want to remove all the data from all your tables  you might want to try the command python manage py flush  This will delete all of the data in your tables  but the tables themselves will still exist   See more here  https   docs djangoproject com en 1 8 ref django-admin
