Django Template field.is_required Work Around

I have a django form that I'm outputing no problem.

My question is with regard to jQuery Validation.

I want to apply jQuery validation to inputs that are required.

I'm using http://docs.jquery.com/Plugins/validation

There's no field.is_required that I can use in the template

so I'm using the help_text and evaluating that in my template.

Just wondering if this is the best way to go about this?

Any advise much appreciated.

Here is:

1) Form Class

class UserDetailsForm(forms.Form):

    city_town = forms.CharField(label='City / Town',max_length=100, required=True, help_text='*')
    state_province = forms.CharField(label='State / Province',max_length=100, required=True, help_text='*')

2) Form output

{% for field in form %}
<开发者_StackOverflowdiv class="fieldWrapper">
{{ field.errors }}
{{ field.label_tag }}: {{ field.help_text }} {{ field }}
</div>
{% endfor %}

3) Form jQuery Validation

// Form Validation Setup
{% for field in form %}
{% if field.help_text == '*' %}
$("input[name='{{ field.html_name }}']").addClass('required');
{% endif %}
{% endfor %}
$("#updateProfileForm").validate();

Is there any better method than the this work around I'm using:

if field.help_text == '*'

I may want to use that field for a tool tip of something later

but for now I'm using an asterisk so I can use it in a loop for jQuery validation

in the template.

Thanks!

When you iterate through a form instance, the __iter__ method returns a BoundField (that handles the rendering and other misc items). This bound field has a field attribute that stores the actual field instance (which does store the required attribute). So you can do

{% if field.field.required %}
    $("input[name='{{ field.html_name }}']").addClass('required');
{% endif %}

Just add this to your model. This will add the class 'required' to your form.

city_town.widget.attrs['class'] = 'required'
