After the commit we issue two calls to the db to get service and get notification. This is because after the commit the ORM wants to ensure that the data model objects are the latest.
So far this is just a proof of concept, but the letter flow needs to be updated and we should be able to get rid of research mode. And it needs some tidy up.
SQS fails if the message body is over 256kb. Normally our messages are
quite small, but if we're using the new save-api-email task with an
email that has a large body, we can get over that limit. If so, handle
the exception and fall back to the existing code path (saving to the
database and sending a deliver-email task, which only has a notification
id.
Instead of saving the email notification to the db add it to a queue to save later.
This is an attempt to alleviate pressure on the db from the api requests.
This initial PR is to trial it see if we see improvement in the api performance an a reduction in queue pool errors. If we are happy with this we could remove the hard coding of the service id.
In a nutshell:
- If POST /v2/notification/email is from our high volume service (hard coded for now) then create a notification to send to a queue to persist the notification to the db.
- create a save_api_email task to persist the notification
- return the notification
- New worker app to process the save_api_email tasks.
By adding `force=True` to request.get_json() the mime type is ignore. If the data is not valid json the method will return a `BadRequestError` we catch that and throw our own error with a clear error message "Invalid JSON supplied in POST data".
If the json is valid return the json data or an empty dict if None is passed in.
This PR improves the error messages if the json is invalid, previously, the error message was "None object type" message which is not very helpful.
Updated the DAO methods which return a single SMS sender and all SMS senders
to only return the non-archived senders. Changed the error raised in the Admin
interface from a SQLAlchemyError to a BadRequestError.
Updated the DAO methods which return a single email reply_to address and
all reply_to addresses to only return the non-archived addresses.
Changed the type of error that gets raised when using the Admin
interface to be BadRequestError instead of a SQLAlchemyError.
Adds support for a new personalisation value type: file upload.
File uploads are represented as a dictionary with a "file" key and
a base64-encoded file data as the key's value:
```
personalisation={
'field1': {'file': '<base64-encoded file contents>'}
}
```
Post notification endpoint checks the request personalisation data
looking for the file uploads in personalisation data. If any are
found and the service has permissions to upload documents the files
are sent to document download API and personalisation values are
replaced with the URLs returned in the document download response.
A fake document URL is returned for simulated notifications, no
documents are stored in Document Download.
Multiple files can be uploaded for one notification by providing
a file upload in more than one personalisation field.
and the client reference. It could confuse the client consumer so best
to remove it from the response altogether.
* Respond with only the notification_id and client_reference
* Updated the test to check for the response without the template
The template in precompiled is only used internally and cannot be
accessed from the UI. It could confuse the client consumer so best to
remove it from the response altogether.
* Remove the template from the dict before returning it and therefore
ensuring it still stays similar to letter
* Updated the test to check for the response without the template
We were already counting the billable units in PDFs that we generate.
We are now also counting the number of billable units in pre-compiled letters
and saving the result.
Pre-compiled letter endpoint uploads PDF contents to S3 directly
instead of creating a letter task to generate PDF using template
preview.
This moves some of the utility functions used by existing letter
celery tasks to app.letters.utils, so that they can be reused by
the API endpoint.
