###What is it?
Parsleyjs is a JavaScript library to do client side data validations.
It does this in a non-intrusive way via adding a data-* attributes to form fields.
When you define a Django form, you get server side validations for free using
the form field attributes. Django-parsley adds these validations to client side, by tagging your form with data-* attributes.
Add parsley to your INSTALLED_APPS.
parsley provides a single class decorator called parsleyfy. Decorate your Form with parsleyfy to get the validations.
Eg.
from parsley.decorators import parsleyfy
@parsleyfy
class FieldTypeForm(forms.Form):
name = forms.CharField(min_length=3, max_length=30)
url = forms.URLField()
url2 = forms.URLField(required=False)
email = forms.EmailField()
email2 = forms.EmailField(required=False)
age = forms.IntegerField()
income = forms.DecimalField()
Your rendered form's HTML will look like this
<p><label for="id_name">Name:</label> <input data-required="true" data-minlength="3" maxlength="30" type="text" data-maxlength="30" id="id_name" name="name" /></p>
<p><label for="id_url">Url:</label> <input type="text" data-required="true" data-type="url" name="url" id="id_url" /></p>
<p><label for="id_url2">Url2:</label> <input type="text" data-type="url" name="url2" id="id_url2" /></p>
<p><label for="id_email">Email:</label> <input type="text" data-required="true" data-type="email" name="email" id="id_email" /></p>
<p><label for="id_email2">Email2:</label> <input type="text" data-type="email" name="email2" id="id_email2" /></p>
<p><label for="id_age">Age:</label> <input type="text" data-required="true" data-type="digits" name="age" id="id_age" /></p>
<p><label for="id_income">Income:</label> <input type="text" data-required="true" data-type="number" name="income" id="id_income" /></p>
Note the data-* attributes.
You could also do
FieldTypeForm = parsleyfy(FieldTypeForm)
Which is the same thing.
Put this form inside a
<form data-validate="parsley">
{{ form.as_p }}
</form>
Include the parsleyjs and you are good to go.
