I want to get the values of checkbox and return it to request.POST

{% for flow in data.flows %}
    <div style="margin-bottom:-27px">
        <div class="w3-bar">
               {% csrf_token %}
               <input type="checkbox" id="{{flow.0}}" name="precedent" value="{{flow.0}}"><label for="scales" >  {{flow.0}} - {{flow.1}}</label>

                   <br>
                <br>
        </div>
    </div>
 % endfor  %}
