Example using GridFS to store loan documents

We need a way to upload loan documents, so we add a file upload HTML element to the maintenance.html template. We also add a loop that displays the currently uploaded documents for this borrower:

<tr><th class="th-right">Loan Documents Stored</th>
    <td class="td-left">
        {% for name in loan_docs %} <br>{{ name }}  {% endfor %}
    </td>
</tr>
<tr>
    <th class="th-right">Upload Loan Document</th>
    <td class="td-left"><input type="file" name="loan_doc" /></td>
</tr>

In the view logic (/path/to/repo/www/chapter_10/maintenance/views.py), we add the following to the payments() method. If there is a borrowerKey value available, we import GridFS and os, and retrieve borrower information (discussed earlier):

    if borrowerKey :
        from gridfs import GridFS
        import os
        borrower = userSvc...
