The `get_bucket_name_and_prefix_for_notification` function was looking
at the `sent_at` or `updated_at` at time of a notification to see which
bucket it was in. Precompiled letters sent through the admin app don't
have either of these times - they only have a `created_at` time, so this
lets the function check `created_at` time too.
this is only applicable when getting a single notification by id. it's
also ignored if the notification isn't a letter.
Otherwise, it overwrites the 'body' field in the response.
If the notification's pdf is available, it returns that, base64
encoded. If the pdf is not available, it returns an empty string.
The pdf won't be available if the notification's status is:
* pending-virus-scan
* virus-scan-failed
* validation-failed
* technical-failure
The pdf will be retrieved from the correct s3 bucket based on its type
Using the created at date for the folder is not always going to work because the pdf created_at date could be just before the cut off date but virus scan and validation has yet to happen. By the time the letters is in the created state, the letter goes into the next days bucket.
It can also happen if the letters is stuck in `pending-virus-scan` and we need to restart the task, and the letters is in a different folder.
- Separated the logic of precompiled and template letters.
- Remove the check for research mode, research mode is not relevant to api calls. The test key is used for testing.
Refactor upload_pdf_letter to accept a precompile boolean to save a query to template.
application. If the Anti-virus app fails due to s3 errors or ClamAV
so does not scan (even after retries) the file at all an error needs
to be raised and the notification set to technical-failure.
Files should be moved to a 'folder' a separate one for ERROR and FAILURE.
* Added new letter task to process the error
* Added a new method to letter utils.py to move a file into an error or
failure folder based on the input
* Added tests to test the task and the utils.py method
- precompiled PDFs sent by test key uploaded to scan bucket
- set status to VIRUS-SCAN-FAILED for pdfs failing virus scan rather than PERMANENT-FAILURE
- Make call to AV app for precompiled letters sent via a test key, and set notification status to PENDING-VIRUS-SCAN
- add function to get reference from filename
- add function to move pdf from scan folder to process folder
- add function to delete pdfs from scan bucket for failed virus scans
* Added is_precompiled_letter method to letter/utils.py
* Added tests for letter/utils.py
* Added tests for the rest endpoint
* Moved the Precompiled name to a central location
* Added hidden field to the test method to create a template
