Usage

Jinja utilities for Invenio applications.

Quick start

This section presents an example of the Invenio-Formatter features. In this section we will create a simple page with a time formatter and a shields.io badge.

First, let us create a new template page on which we will render some text, and save it to some location (e.g.: /home/myuser/templates/index.html)

{% set mydate = mydate|from_isodate -%}
Today is {{ mydate.strftime('%Y-%m-%d') }}

Your book: {{ badge_svg('isbn','9780399547331')|safe }}

Create a new Flask application and set some configuration for badge generation:

>>> from flask import Flask
>>> app = Flask('TestApp', template_folder='/home/myuser/templates')
>>> app.config.update(FORMATTER_BADGES_ALLOWED_TITLES=('isbn', 'ISBN', ))
>>> app.config.update(FORMATTER_BADGES_TITLE_MAPPING={'isbn': 'ISBN',})

Note

By default the template_folder is the directory templates at the root of your flask application.

load the Invenio-Formatter extension and run the application:

>>> from invenio_formatter import InvenioFormatter
>>> ext_fmt = InvenioFormatter(app)
>>> app.run() 

You should now be able to access the index page with formatted date and badge examples at http://localhost:5000.

Badges endpoints

In addition of generating an image of a shield badge, a badge-rendering endpoint is also available for easy embedding on other websites.

You can modify the template as follows:

{% set mydate = mydate|from_isodate -%}
Today is {{ mydate.strftime('%Y-%m-%d') }}

Your book (with badge URL: ):
    <img src="{{ url_for('invenio_formatter_badges.badge',
     title='isbn', value='9780399547331', ext='svg') }}"></img>

Your badge will be visible on the page as before, and also directly accessible at http://localhost:5000/badge/ISBN/9780399547331.svg.
