Django Python LoadData: Error Problem Installing Fixture - mysql

Question

First I have migrate and makemigrations and then I have dump data with this command:
python manage.py dumpdata --exclude auth.permission --exclude contenttypes > dvvv.json
I have tried to flush the database but when I execute python manage.py loaddata dvvv.json the following error occurs:
pymysql.err.ProgrammingError: (1146, "Table 'webcnytc_prilert_tool.Prilert_confirmationemail' doesn't exist")
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
