Microsoft-and-Google-OAuth-2.0-with-email-read-access

(1) Project Setup:

-> The project is based on Django, a high-level web framework written in Python.
-> We use Django to create a web application that will allow users to sign in with their Google and Microsoft accounts.
-> The project has a folder structure with the standard Django app setup.

(2) Authentication with Google:

-> The login_with_google view handles the initial step of the Google OAuth 2.0 authentication flow. It redirects the user to Google's authorization page.
-> After granting access, the callback view handles the callback from Google. It fetches the user's Google credentials and stores the access token in the user's session for later use.
-> The user's Gmail account (email) is saved in the database and associated with the Django user.

(3) Authentication with Microsoft:

-> Although the code for Microsoft authentication is not shown in the provided views, it is implied that you are using the django-microsoft-auth library to handle Microsoft OAuth 2.0 authentication.
-> Similar to Google authentication, the user's Microsoft account is saved in the database and associated with the Django user.

(4) Listing Gmail Accounts:

-> The gmail_accounts view fetches all the Gmail accounts saved in the database and displays them on the gmail_accounts.html template.
-> This template shows a list of Gmail accounts, and the user can click on a specific Gmail account to view its incoming emails.

(5) Fetching Incoming Emails for a Gmail Account:

-> The gmail_incoming_mails view fetches the last 100 incoming emails for the selected Gmail account and sorts them by date in descending order.
-> It uses the Gmail API to interact with the Gmail mailbox and fetch the emails.
-> The emails are displayed on the gmail_incoming_mails.html template.

(6) Parsing and Displaying Email Data:

-> For each incoming email, the view fetches detailed information like sender name, sender email, subject, and body from the email payload.
-> The parse_date function parses the date string obtained from the email headers to a Python datetime object.
-> The view renders this information in a formatted manner on the template.

(7) Templates:

-> There are several templates used in the project, such as login.html, thank_you.html, gmail_accounts.html, gmail_incoming_mails.html, microsoft_incoming_mails.html, gmail_account_not_found.html, and no_emails_found.html.
-> These templates use Bootstrap CSS and JS for better UI and styling.

(8) Session and Access Tokens:

-> The project uses Django's session framework to store the user's access token for later use during API requests to Google and Microsoft.
-> The access token is stored in the user's session and retrieved when needed to make API calls.

Overall, the project allows users to sign in with their Google and Microsoft accounts, lists the Gmail accounts associated with the user, and fetches the last 100 incoming emails for a selected Gmail account. It also displays the emails in a formatted manner with sender details, subject, and body content. The UI is enhanced using Bootstrap for better styling and responsiveness.
