Storing File in Json Field, Django

Question

I'm working on a project which requires users to submit posts of various forms.

There are posts that require images and others that require videos. To deal with this and other complexities, I was thinking of using jsonfields.

My current issue is handing files, that is images and videos. I was hoping to be able to store the file url in a field in the json field but I haven't come across anything like that on the internet.

Is it possible or advisable to go on with this approach? If so, how can it be done?

You can use Django's FileField https://docs.djangoproject.com/en/3.1/ref/models/fields/#filefield Works well with django-rest-framework. It works exactly as you expect (i.e. returns URL to the saved file).

I prefer to use S3 as a storage via S3Boto3Storage from django-storages. You can define a custom storage like

class MyCustomStorage(S3Boto3Storage):
    location = 'private'
    default_acl = 'private'
    file_overwrite = False
    custom_domain = False

and then in your model:

class MyModel(models.Model):
    ...more fields...
    attachment = models.FileField(storage=MyCustomStorage(), null=True)
    ...more fields...

You can use S3 like services for that either AWS S3 or any alternative. If you need a local one and don't want to go with 3-party services you can take a look on minio which can be setup locally on any server. The idea is following You setup minio/s3 service and use it as media storage for you django app (check out django-storages )

So whenever you'll create a post you can upload all the media or static files to the s3 and use an url in your post object instead.
