I wrote a python script to easily reset a django project. I hope it helps
you.
Just put it in the folder where manage.py file is and run it.
import os
import shutil
from pprint import pprint
folders = []
base_dir = os.path.dirname(os.path.realpath(__file__))
def get_directory_list():
global folders
global base_dir
for root, d_names, f_names in os.walk(base_dir):
for name in d_names:
folders.append(os.path.join(root, name))
folders = sorted(folders)
return folders
def delete_pycache():
global folders
for folder in folders:
if folder.endswith("__pycache__"):
shutil.rmtree(folder)
print("All __pycache__ files deleted.")
return None
def delete_migrations():
global folders
for folder in folders:
if folder.endswith("migrations"):
for item in os.listdir(folder):
if not item.endswith("__init__.py"):
os.remove(os.path.join(folder, item))
print("All migration files deleted.")
return None
def delete_sqlite3():
global base_dir
db_file = os.path.join(base_dir, "default.sqlite3")
if os.path.exists(db_file):
os.remove(db_file)
def main():
global folders
try:
get_directory_list()
delete_pycache()
delete_migrations()
delete_sqlite3()
print("All operations performed successfully.")
except Exception as e:
print("There was some error")
if __name__ == "__main__":
main()
