HTML Templating
|
|
===============
|
|
|
|
pygeoapi uses `Jinja`_ as its templating engine to render HTML and `Flask`_ to provide route paths of the API that returns HTTP responses. For complete details on how to use these modules, refer to the `Jinja documentation`_ and the `Flask documentation`_.
|
|
|
|
The default pygeoapi configuration has ``server.templates`` commented out and defaults to the pygeoapi ``pygeoapi/templates`` and ``pygeoapi/static`` folder. To point to a different set of template configuration, you can edit your configuration:
|
|
|
|
.. code-block:: yaml
|
|
|
|
server:
|
|
templates:
|
|
path: /path/to/jinja2/templates/folder # jinja2 template HTML files
|
|
static: /path/to/static/folder # css, js, images and other static files referenced by the template
|
|
|
|
**Note:** the URL path to your static folder will always be ``/static`` in your deployed web instance of pygeoapi.
|
|
|
|
Your templates folder should mimic the same file names and structure of the default pygeoapi templates. Otherwise, you will need to modify ``api.py`` accordingly.
|
|
|
|
Note that you need only copy and edit the templates you are interested in updating. For example,
|
|
if you are only interested in updating the ``landing_page.html`` template, then create your own version
|
|
of the only that same file. When pygeoapi detects that a custom HTML template is being used,
|
|
it will look for the custom template in ``server.templates.path``. If it does not exists, pygeoapi
|
|
will render the default HTML template for the given endpoint/requuest.
|
|
|
|
Linking to a static file in your HTML templates can be done using Jinja syntax and the exposed ``config['server']['url']``:
|
|
|
|
.. code-block:: html
|
|
|
|
<!-- CSS example -->
|
|
<link rel="stylesheet" href="{{ config['server']['url'] }}/static/css/default.css">
|
|
<!-- JS example -->
|
|
<script src="{{ config['server']['url'] }}/static/js/main.js"></script>
|
|
<!-- Image example with metadata -->
|
|
<img src="{{ config['server']['url'] }}/static/img/logo.png" title="{{ config['metadata']['identification']['title'] }}" />
