Re: How to show a list of products as checkboxes?

Thank you. crispy_forms are on my list, but I'm trying to learn Django's forms first.

You may want to look at Django crispy forms as a way to simplify form creation and layout;

For example, handling of checkboxes:

My model:

class Product(models.Model):
    descr = models.CharField(max_length=100)
    cost = models.DecimalField(max_digits=5, decimal_places=2)

For every row stored in the table represented by this model, in the template I would like to render the description and a checkbox so that the user can check it if he wants to buy it.

Product 1 <input type=checkbox name=prodName1 value='Y'/>
Product 2 <input type=checkbox name=prodName2 value='Y'/>Product 2 <input type=checkbox name=prodName3 value='Y'/>

I can't figure out how to do that. I would be happy to manually render the form fields as checkboxes, but I don't know how to get the field id in the template.

For example, 

{% for field in form %}

<div id="{{ field.auto_id }}_container">

    <div>
      <label for="{{ field.auto_id }}">{{ field. }}:</label> <input id="id_test1" name="test1" type="checkbox" />
    </div>
      <!--
    <div id="id_test1_errors">

    </div>
    -->
  </div>


    {{ field.help_text }}
    <div>
      {{ field.label_tag }} {{ field }}
    </div>
  {% endfor %}

If this were java, I would write something like this in the jsp:

<c:forEach var="row" items="${products.result.rows}">
<input type=checkbox name='<c:out value=${row.id}/>' value='Y' /> <c:out value=${row.descr} />
</c:forEach>
But I don't know how to do that with Python and Django. 

And I may be coming at this totally wrong, so if that is the case, please feel free to tell me how I should be trying to do this.

Thank you,
