Setting Environment Variables in PyCharm for Django Development

When working with Django projects, it becomes necessary to set environment variables to configure database settings and other parameters. Instead of manually setting these variables or using external bash files, PyCharm offers a convenient way to manage environment variables within its run configurations menu.

To set environment variables in PyCharm:

1. Open the Run Configuration selector located in the top-right corner of the IDE and click "Edit Configurations..."
2. In the configuration window, select the desired Python or Django file from the menu.
3. Find the "Environmental variables" section and click "Edit..."
4. A dialog box will appear where you can add, edit, or remove environment variables.
5. Enter the desired variables and click "OK" to save the changes.

For instance, to set the variables:

export DATABASE_URL=postgres://127.0.0.1:5432/my_db_name
export DEBUG=1

Simply add them to the "Environmental variables" dialog box as key-value pairs:

DATABASE_URL=postgres://127.0.0.1:5432/my_db_name
DEBUG=1

Once configured, the environment variables can be accessed within your code using the os.environ module. For example, to access the value of the DATABASE_URL variable:

<code class="python">import os
print(os.environ['DATABASE_URL'])</code>

By setting environment variables directly in PyCharm's run configurations, you can streamline your Django development process and avoid the need for external configuration management.
