We make use of nginx subrequests to block media file downloads while
we check for access rights. The request is then proxied to the object
storage engine and authorization is added via the "Authorization"
header. This way the media urls are static and can be stored in the
document's json content without compromising on security: access
control is done on all requests based on the user cookie session.
We only rely on S3 to store attachments for a document. Nothing
is persisted in the database as the image media urls will be
stored in the document json.
The linter was complaining about too many lines
in test_api_document_accesses.py. We split the
test file into two files to fix the warning.
We move as well the test_api_document tests to
the documents folder.
We override the perform_create method of
the DocumentViewSet to save the document with
the id provided if a id is provided in the request.
We do that because in offline mode we will create
the document locally and we will need to save it
with the id created locally to have our next
requests to the server to be able to find the
document with the id provided.
user field was displaying the userid, but we
need to return the user object on the
DocumentAccessSerializer, so we can show the
user email on the frontend.
We add the user_id field in write_only mode, so
we can keep create and update.
Versions are retrieved directly from object storage and served on API
endpoints. We make sure a user who is given access to a document will
only see versions that were created after s.he gained access.
The content field is a writable property on the model which is persisted
in object storage. We take advantage of the versioning, robustness and
scalability of S3.
We would like to duplicate a template from the frontend.
For that we need to access the css and code of the template.
So we add the css and code to the template endpoint.
partial_update action was missing for the permission.
So when we were patching the template,
it was not working.
This commit adds the partial_update action
to the abilities.
