Added Email Alert Functionality

[kunalsz]

I had already implemented the email alerting functionality but given the new Alert classes ,I have reimplemented it.
In reference to the issue #126

Changes made

• Google's SMTP service has been implemented. This requires an app password and your email address to send emails
• A new file inside impossible_travel/alerting is created email_alerting.py to send the emails to a specific address using Django's send_email functionality
• tests are created to check if the email is sent correctly or not

Outcomes

• emails are generated successfully when tests are ran
• test is getting failed even when the email is being recieved in the reciever's mailbox. The issue can be with the @patch functionality implemented in the tests/test_alert_email.py. Will work on this.

placeholders are left in the place of actual email addresses and app password

Looking forward for your insights and advices !

Looks good to me. Tommorrow We are going to fix the github action linter bug (it is on our side, I've already checked) and merge the PR

[ManofWax]

Hi @kunalsz, can you run linters and formatters as documented here? https://github.com/certego/BuffaLogs/blob/main/CONTRIBUTING.md

[kunalsz]

@ManofWax sure, I'll do that and update you.

[kunalsz]

Hi @ManofWax , there were some problems in linting on my side. I have fixed them and linted code. Please review it.

Hi @kunalsz , linters have been fixed in the PR #146. So, please align your feature branch with the develop one and resolve the conflicts with your code

[kunalsz]

@Lorygold I will align my code with the updates soon.

Hi @kunalsz, there's an error in your test:

  File "/home/runner/work/BuffaLogs/BuffaLogs/buffalogs/impossible_travel/tests/test_alert_email.py", line 42, in test_email_args
    self.assertEqual(email.from_email, "BuffaLogs Alerts SENDER_EMAIL_ADDRESS")
AssertionError: 'BuffaLogs Alerts SENDER_EMAIL_ADRESS' != 'BuffaLogs Alerts SENDER_EMAIL_ADDRESS'
- BuffaLogs Alerts SENDER_EMAIL_ADRESS
+ BuffaLogs Alerts SENDER_EMAIL_ADDRESS

Before committing, you can run tests locally launching > ./manage.py test in order to check if the tests pass.

@Lorygold I have fixed that error but I am facing this error which is not originating from my code

This can be fixed by updating this code in buffalogs/impossible_travel/tasks.py

TO
s.aggs.bucket("login_user", "terms", field="user.name.keyword", size=10000)

Should I proceed with that ?

It's an error that is present only in your workspace, so probably I think that you didn't load the template on Elasticsearch, running:

> cd config/elasticsearch/
> ./load_templates.sh

Please, commit again to: s.aggs.bucket("login_user", "terms", field="user.name", size=10000)
