[Answer]-Django post returning token not post data

You need to put the name attribute on the select element, not the option.

But you should probably be using Django’s forms framework, anyway.

As @Daniel told that, You need to add name field to select tag not for option tag,

<select name='customer_id'>
        {% for item in customer %}
        <option value={{ item.customer_id }} >{{ item.customer_name }}</option>
        {% endfor %}
        <input type = 'submit' value='Edit'>
        </select>
