Add a way to mock s3 for development

[ABODFTW]

For people using this tool and developing it, I think it would make life easier if there is a documented way on how to mock s3, so there is no need for an AWS S3 account.

I.e

• S3Mock
• MockS3
• Fake-s3 Ruby jam

I'm not sure where to start, so if I can get some guidance, I would like to contribute

Probably the quickest way to get what you want is the docker image for Localstack. It's not quite a mock, but it implements s3 and other AWS services locally without making a mess.

Oh thanks for the comment, I've settled with s3erver which is an npm package, and its been great so far.

But I think it would be good if we documented options, not everyone have access to s3 bucket.

If you think it's a good idea, let me know and I will send a pr

Not sure about Localstack or s3erver, I'll just add minio as a relatively small (64mb docker image) s3-compatible server.
Worked fine with django-storages for local development.

I too would like to +1 for a way to - or ideas how to - implement "mock" upload to S3 functionality. In my case, I want a FileField during local development, and an S3DirectField in all other environments. Things I thought about / tried:

• overriding the form URL field widget during init with a ClearableFileInput (doesn't work because a filefield and urlfield are two different things)
• adding a null=True models.FileField() to my existing model containing the S3DirectField

Probably more elegant ways. Would love some ideas.
