I don't think you will be able to do this using the built-in MessageSender class as this is just a wrapper which calls a server backend API which doesn't support setting priority:
from dataiku.core import base, flow
import os.path as osp, os, shutil
import json
from dataiku.core.intercom import backend_json_call
class MessageSender():
"""
This is a handle to interact with a message sender
"""
def __init__(self, channel_id, type=None, configuration={}):
self.type = type
self.channel_id = channel_id
self.configuration = configuration
self.channel = None
def _repr_html_(self,):
s = "MessageSender[ <b>%s</b> ]" % (self.channel_id)
return s
def get_channel(self):
if self.channel is None:
self.channel = backend_json_call("integration-channels/get", data={
"id" : self.channel_id
})
return self.channel
def send(self, message, variables={}, project_key=None, **kwargs):
final_params = self.configuration.copy()
final_params.update(kwargs)
final_params['channelId'] = self.channel_id
final_params['message'] = message
if project_key is None or len(project_key) == 0:
project_key = os.environ.get("DKU_CURRENT_PROJECT_KEY", None)
data = {
"projectKey": project_key,
"messaging" : json.dumps({
"type" : self.type,
"configuration" : final_params,
}),
"variables" : json.dumps(variables)
}
return backend_json_call("scenarios/send-message/", data=data, err_msg="Failed to send message")
You can however use the dss-plugin-sendmail, which you can customise at will or even de-pluginise into a custom Python library, and make the required changes on the send_email() function to allow for setting the priority as shown in this SO answer.
