Django Project Rename Command: Missing Required Argument

# Help! Can't rename my Django project

I'm following a Django e-commerce tutorial and hit a snag. After installing packages and tweaking requirements.txt, I tried to rename the project. But I got this error:

> manage.py rename: error: the following arguments are required: new

I'm using a custom management command for renaming. Here's the code:

```python
import os
from django.core.management.base import BaseCommand

class RenameProjectCommand(BaseCommand):
    help = 'Changes Django project name'

    def add_arguments(self, parser):
        parser.add_argument('old_name', type=str, nargs='+',
                            help='Current project folder name')
        parser.add_argument('new_name', type=str, nargs='+',
                            help='Desired project name')

    def handle(self, *args, **kwargs):
        old_name = kwargs['old_name'][0]
        new_name = kwargs['new_name'][0]

        # Renaming logic here
        files_to_update = [f'{old_name}/settings/base.py',
                           f'{old_name}/wsgi.py', 'manage.py']

        for file_path in files_to_update:
            with open(file_path, 'r') as f:
                content = f.read()
            content = content.replace(old_name, new_name)
            with open(file_path, 'w') as f:
                f.write(content)

        os.rename(old_name, new_name)

        self.stdout.write(self.style.SUCCESS(
            f'Project renamed to {new_name}'))

What am I doing wrong? How can I fix this error?

Reviewing your code, the error indicates that the required ‘new’ argument isn’t being provided when you run the command. This means that the command is expecting two positional arguments—your old project name and your new one—but only one is being passed.

Make sure you run the command like this:

python manage.py rename old_project_name new_project_name

In addition, consider adjusting your argument configuration. Declaring the arguments with ‘nargs’ set to ‘+’ allows multiple values, which might lead to unexpected behavior. Defining them without the ‘+’ could prevent potential issues.

hey max, looks like ur missin the new name when runnin the command. try this:

python manage.py rename oldname newname

make sure u replace ‘oldname’ and ‘newname’ with ur actual project names. if that doesnt work, double check ur command file. hope this helps!

Hey Max_31Surf! That’s a pretty neat custom command you’ve got there for renaming projects. I’m curious though - how exactly are you running the command? It looks like you might be missing the ‘new’ argument when you call it.

Have you tried something like this?

python manage.py rename old_project_name new_project_name

Where ‘old_project_name’ is your current project name and ‘new_project_name’ is what you want to change it to. The error message suggests you’re not providing that second argument.

Also, just wondering - any particular reason you’re using a custom command for this instead of just manually renaming files? I’m always interested in learning new Django tricks!

Let me know if that helps or if you’re still stuck. Happy to brainstorm more if needed!
