# Microsoft Graph sample Ruby on Rails app

[![Ruby](https://github.com/microsoftgraph/msgraph-sample-rubyrailsapp/actions/workflows/ruby.yml/badge.svg)](https://github.com/microsoftgraph/msgraph-sample-rubyrailsapp/actions/workflows/ruby.yml) ![License.](https://img.shields.io/badge/license-MIT-green.svg)

This sample demonstrates how to use the Microsoft Graph REST API to access data in Office 365 from Ruby on Rails apps.

> **NOTE:** This sample was originally built from a tutorial published on the [Microsoft Graph tutorials](https://learn.microsoft.com/graph/tutorials) page. That tutorial has been removed.

## Prerequisites

To run the completed project in this folder, you need the following:

- [Ruby](https://www.ruby-lang.org/en/downloads/)
- [SQLite3](https://sqlite.org/index.html)

This sample was written for Ruby 3.1.2.

## Register a web application with the Microsoft Entra admin center

1. Open a browser and navigate to the [Microsoft Entra admin center](https://entra.microsoft.com). Login using a **Work or School Account**.

1. Expand **Identity** in the left-hand navigation, expand **Applications**, then select **App registrations**.

1. Select **New registration**. On the **Register an application** page, set the values as follows.

- Set **Name** to `Ruby Graph Tutorial`.
    - Set **Supported account types** to **Accounts in any organizational directory and personal Microsoft accounts**.
    - Under **Redirect URI**, set the first drop-down to `Web` and set the value to `http://localhost:3000/auth/microsoft_graph_auth/callback`.

1. Choose **Register**. On the **Ruby Graph Tutorial** page, copy the value of the **Application (client) ID** and save it, you will need it in the next step.

1. Select **Certificates & secrets** under **Manage**. Select the **New client secret** button. Enter a value in **Description** and select one of the options for **Expires** and choose **Add**.

1. Copy the client secret value before you leave this page. You will need it in the next step.

## Configure the sample

1. Rename the `./graph-sample/config/oauth_environment_variables.rb.example` file to `oauth_environment_variables.rb`.

1. Edit the `oauth_environment_variables.rb` file and make the following changes.
    1. Replace `YOUR_APP_ID_HERE` with the **Application Id** you got from the App Registration Portal.
    1. Replace `YOUR_APP_SECRET_HERE` with the secret you got from the App Registration Portal.

1. In your command-line interface (CLI), navigate to the `./graph-sample` directory and run the following command to install requirements.

```Shell
    bundle install
    ```

1. In your CLI, run the following command to initialize the app's database.

```Shell
    rake db:migrate
    ```

## Run the sample
