Configure Your MongoDB Connection

Specify target database in connection string

When connecting to an Atlas cluster, you must specify the database that you want to interact with as the default database in your connection string. You must add the database name to your connection string after the hostname.

The following example specifies the sample_restaurants target database in a sample connection string:

mongodb+srv://user0:pass123@mongo0.example.com/sample_restaurants

Specify connection in mongoid.yml

At the root level of your project, create a config directory. Then, create a file in this directory called mongoid.yml.

Paste the following configuration into the mongoid.yml file, making sure to replace the <connection string> placeholder with your connection string that references the target database:

development:
  clients:
    default:
      uri: <connection string>

After completing these steps, your Sinatra web application is ready to connect to MongoDB.
