Storage

uMap stores metadata (such as owner, permissions…) in PostgreSQL, and the data itself (the content of a layer) in geojson format, by default on the local file system, but optionally in a S3 like server.

This can be configured through the STORAGES settings. uMap will use three keys:

• default, used only for the pictogram files, it can use whatever storage suits your needs
• staticfiles, used to store the static files, it can use whatever storage suits your needs, but by default uses a custom storage that will add hash to the filenames, to be sure they are not kept in any cache after a release
• data, used to store the layers data. This one should follow the uMap needs, and currently uMap provides only two options: umap.storage.UmapFileSystem and umap.storage.UmapS3

Default settings:

This will use the file system for everything, including the data.

STORAGES = {
    "default": {
        "BACKEND": "django.core.files.storage.FileSystemStorage",
    },
    "data": {
        "BACKEND": "umap.storage.UmapFileSystem",
    },
    "staticfiles": {
        "BACKEND": "umap.storage.UmapManifestStaticFilesStorage",
    },
}

Using S3

To use an S3 like server for the layers data, the first thing is to install the needed dependencies: pip install umap-project[s3].

Then, change the STORAGES settings with something like this:

STORAGES = {
    "default": {
        "BACKEND": "django.core.files.storage.FileSystemStorage",
    },
    "data": {
        "BACKEND": "umap.storage.UmapS3",
        "OPTIONS": {
            "access_key": "xxx",
            "secret_key": "yyy",
            "bucket_name": "umap",
            "region_name": "eu",
            "endpoint_url": "http://127.0.0.1:9000",
        },
    },
    "staticfiles": {
        "BACKEND": "umap.storage.UmapManifestStaticFilesStorage",
    },
}

See more about the configuration on the django-storages documentation.
