Django PDF utils
Project description
A simple django app to generate PDF documents.
Installation
In your settings.py, add pdfutils to your INSTALLED_APPS.
(r’^reports/’, include(pdfutils.site.urls)), to your urls.py
Create a report.py file in any installed django application.
Create your report(s)
Profit!
Note: If you are using buildout, don’t forget to put pdfutils in your eggs section or else the django-pdfutils dependencies wont be installed.
Example report
Reports are basically views with custom methods and properties.
# -*- coding: utf-8 -*-
from django.contrib.auth.models import User
from django.core.urlresolvers import reverse
from django.utils.translation import ugettext as _
from pdfutils.reports import Report
from pdfutils.sites import site
from pdfutils.utils import memoize
class MyUserReport(Report):
title = _('Users')
template_name = 'myapp/reports/users-report.html'
slug = 'users-report'
orientation = 'portrait'
@memoize
def get_users(self):
"""
This method is not necessary, it is used to showcase the
memoize decorator which is included in utils. This prevent
methods from computing their output twice.
"""
return User.objects.filter(is_staff=True)
def get_styles(self):
"""
It is possible to add or override style like so
"""
self.styles.append('myapp/css/users-report.css')
return super(AccountStatementReport, self).get_styles()
def filename(self):
"""
The filename can be generated dynamically and translated
"""
return _('Users-report-%(count)s.pdf') % {'count': self.get_users().count() }
def get_context_data(self):
"""
Context data is injected just like a normal view
"""
context = super(AccountStatementReport, self).get_context_data()
context['user_list'] = self.get_users()
return context
site.register(MyUserReport)The slug should obviously be unique since it is used to build the report URL.
For example, with the default settings and URLs, the URL for report above would be /reports/users-report/.
Example template
<html>
<head>
{{ STYLES|safe }}
</head>
<body class="{% if landscape %}landscape{% else %}portrait{% endif %}">
<ul>
{% for user in user_list %}
<li>{{ user }}</li>
{% endif %}
</ul>
</body>
</html>Some template variables are injected by default in reports:
title
slug
orientation
MEDIA_URL
STATIC_URL
STYLES
Overriding default CSS
Since the default CSS (base.css, portrait.css, landscape.css) are normal static files, they can be overrided from any other django app which has a pdfutils folder in their static folder.
Note: Be sure your applications are listed in the right order in INSTALLED_APPS !
