A simple way to use `jSignature jQuery plugin <https://github.com/brinley/jSignature/blob/master/README.md>`_ in your `Django <https://www.djangoproject.com>`_ 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.
|
||||
* A template filter to render signatures as base64 image urls.

|
||||
==================
|
||||
Installation
|
||||
==================
|
||||
|
||||
::
|
||||
|
||||
pip install django-jsignature
|
||||
|
||||
==================
|
||||
Usage
|
||||
==================
|
||||
|
||||
* Add ``jsignature`` to your ``INSTALLED_APPS``:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# settings.py
|
||||
INSTALLED_APPS = (
|
||||
...
|
||||
'jsignature',
|
||||
)
|
||||
|
||||
* Use provided model field (for easy storage):
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# models.py
|
||||
from django.db import models
|
||||
from jsignature.fields import JSignatureField
|
||||
|
||||
class SignatureModel(models.Model):
|
||||
signature = JSignatureField()
|
||||
|
||||
* In your form template
|
||||
|
||||
.. code-block:: html+django
|
||||
|
||||
{{ form.media }}
|
||||
<form action="" method="post">
|
||||
{{ form }}
|
||||
<input type="submit" value="Save" />
|
||||
{% csrf_token %}
|
||||
</form>
|
||||
|
||||
* Render image from db value in your display template:
|
||||
|
||||
.. code-block:: html+django
|
||||
|
||||
{# yourtemplate.html #}
|
||||
{% load jsignature_filters %}
|
||||
|
||||
<img src="{{ obj.signature|signature_base64 }}" alt="{{ obj }}" />
|
||||
|
||||
|
||||
* 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.
|
||||
|
||||
It is strongly suggested to take example from ``example_project``, which is
|
||||
`located in this repo <https://github.com/fle/django-jsignature/tree/master/example_project>`_
|
||||
|
||||
==================
|
||||
Customization
|
||||
==================
|
||||
|
||||
JSignature plugin options are available in python:
|
||||
|
||||
* Globally, in your settings:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# settings.py
|
||||
JSIGNATURE_WIDTH = 500
|
||||
JSIGNATURE_HEIGHT = 200
|
||||
|
||||
* Specifically, in your form:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# forms.py
|
||||
from jsignature.forms import JSignatureField
|
||||
from jsignature.widgets import JSignatureWidget
|
||||
|
||||
JSignatureField(widget=JSignatureWidget(jsignature_attrs={'color': '#CCC'}))
|
||||
|
||||
Available settings are:
|
||||
|
||||
* ``JSIGNATURE_WIDTH`` (width)
|
||||
* ``JSIGNATURE_HEIGHT`` (height)
|
||||
* ``JSIGNATURE_COLOR`` (color)
|
||||
* ``JSIGNATURE_BACKGROUND_COLOR`` (background-color)
|
||||
* ``JSIGNATURE_DECOR_COLOR`` (decor-color)
|
||||
* ``JSIGNATURE_LINE_WIDTH`` (lineWidth)
|
||||
* ``JSIGNATURE_UNDO_BUTTON`` (UndoButton)
|
||||
* ``JSIGNATURE_RESET_BUTTON`` (ResetButton)
|
||||
|
||||
==================
|
||||
In your models
|
||||
==================
|
||||
|
||||
If you want to store signatures easily, a provided mixin gives a ``signature``
|
||||
and a ``signature_date`` that update themselves:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from django.db import models
|
||||
from jsignature.mixins import JSignatureFieldsMixin
|
||||
|
||||
class JSignatureModel(JSignatureFieldsMixin):
|
||||
name = models.CharField()
|
||||
|
||||
|
||||
==================
|
||||
In your forms
|
||||
==================
|
||||
|
||||
* If you need more precise handling of the form field, you can use it directly:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# forms.py
|
||||
from django import forms
|
||||
from jsignature.forms import JSignatureField
|
||||
|
||||
class SignatureForm(forms.Form):
|
||||
signature = JSignatureField()
|
||||
|
||||
|
||||
* And upon saving, have direct access to the image with ``draw_signature()``
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
# views.py
|
||||
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)
|
||||
|
||||
|
||||
==================
|
||||
Example project
|
||||
==================
|
||||
|
||||
If you want to have a demo of this package, just use the example project:
|
||||
|
||||
.. code-block:: shell
|
||||
|
||||
git clone https://github.com/fle/django-jsignature.git
|
||||
cd django-jsignature
|
||||
python -m venv venv
|
||||
source venv/bin/activate
|
||||
pip install -r requirements.txt
|
||||
pip install -e .
|
||||
cd example_project
|
||||
./manage.py migrate
|
||||
./manage.py createsuperuser
|
||||
|
||||
Fill the user info, launch django with ``./manage.py runserver`` and head over
|
||||
to `http://127.0.0.1:8000/ <http://127.0.0.1:8000/>`_, you can also
|
||||
`login to the admin <http://127.0.0.1:8000/admin>`_ with the credentials your
|
||||
provided.
