应用程序 Jsignature 正是我所需要的。看起来不错。对我来说不幸的是，我无法让它工作。这个应用程序适合 Django 1.10.5 和 Python 3.5.2 吗？

我使用了示例代码，没有进行任何更改，但我仍然只得到按钮而不是签名字段。

我想做的是：使用来自网站的数据（由用户填写）我创建一个 pdf。为此，我使用 Wea​​syprint 和模板。这一切都很好。现在我也想将来自同一模板的签名添加到 de pdf 中。我怎么做？有人可以帮助我吗？

This is a new project and I only see the safe button:

settings.py:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'jsignature',
]

urls.py:
from django.conf.urls import url
from django.contrib import admin
from django.views.generic import TemplateView


urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^sign/$', TemplateView.as_view(template_name='my_template.html'))
]

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)

forms.py:
from django import forms
from jsignature.forms import JSignatureField


class SignatureForm(forms.Form):
    signature = JSignatureField()

my_template.html:
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    {{ form.media }}
    <form action="." method="POST">
        {% for field in form %}
            {{ field.label_tag }}
            {{ field }}
        {% endfor %}
        <input type="submit" value="Save"/>
        {% csrf_token %}
    </form>
</body>
</html>

保存按钮
