Use jSignature jQuery plugin in your django projects

Project description

A simple way to use jSignature jQuery plugin in your Django projects.

It provides:

  • A form field and a form widget to handle jquery plugin through a Django form;
  • A model field to store a captured signature;
  • A mixin adding two fields (signature / signature_date) in any of your Django models.
Latest PyPI version Build status Coverage status


For now:

pip install django-jsignature


  • Add jsignature to your INSTALLED_APPS:
  • Use provided form field and widget:
from django import forms
from jsignature.forms import JSignatureField

class SignatureForm(forms.Form):
    signature = JSignatureField()
  • In your template
{{ }}
<form action="." method="POST">
    {% for field in form %}
        {{ field.label_tag }}
        {{ field }}
    {% endfor %}
    <input type="submit" value="Save"/>
    {% csrf_token %}
  • Render image after form validation:
from jsignature.utils import draw_signature
from myapp.forms import SignatureForm

def my_view(request):
    form = SignatureForm(request.POST or None)
    if form.is_valid():
        signature = form.cleaned_data.get('signature')
        if signature:
            # as an image
            signature_picture = draw_signature(signature)
            # or as a file
            signature_file_path = draw_signature(signature, as_file=True)
  • By default, jSignature is made to work outside of admin, requiring that you include the jQuery library in your <head>.

    If you want to use jSignature in the Django admin site, set the JSIGNATURE_JQUERY setting to admin. Otherwise if set to any url pointing to jQuery, it will be automatically included.


JSignature plugin options are available in python:

  • Globally, in your settings:
  • Specifically, in your form:
from jsignature.forms import JSignatureField
from jsignature.widgets import JSignatureWidget

JSignatureField(widget=JSignatureWidget(jsignature_attrs={'color': '#CCC'}))

Available settings are:

  • JSIGNATURE_BACKGROUND_COLOR (background-color)
  • JSIGNATURE_DECOR_COLOR (decor-color)


If you want to store signatures, provided mixin gives a signature and a signature_date that update themselves:

from django.db import models
from jsignature.mixins import JSignatureFieldsMixin

class JSignatureModel(JSignatureFieldsMixin):
    name = models.CharField()
