Alternates template

Example of a generic alternates template:

{% extends "layout.html" %}
{% block content %}
    <h1>{{ register_name }} Linked Data API</h1>
    {% if class_uri %}
        <h3>Alternates view of a <a href="{{ class_uri }}">{{ class_uri }}</a></h3>
    {% else %}
        <h3>Alternates view</h3>
    {% endif %}
    {% if instance_uri %}
        <h3>Instance <a href="{{ instance_uri }}">{{ instance_uri }}</a></h3>
    {% endif %}
    <p>Default profile: <a href="{{ request.base_url }}?_profile={{ default_profile_token }}">{{ default_profile_token }}</a></p>
    <table class="pretty">
    <tr><th>View</th><th>Formats</th><th>View Desc.</th><th>View Namespace</th></tr>
    {% for v, vals in profiles.items() %}
            <tr>
                <td><a href="{{ request.base_url }}?_profile={{ v }}">{{ v }}</a></td>
                <td>
                {% for f in vals['formats'] %}
                    <a href="{{ request.base_url }}?_profile={{ v }}&_format={{ f }}">{{ f }}</a>
                    {% if loop.index != vals['formats']|length %}<br />{% endif %}
                {% endfor %}
                </td>
                <td>{{ vals['namespace'] }}</td>
                <td>{{ vals['comment'] }}</td>
            </tr>
    {% endfor %}
    </table>
{% endblock %}

The alternates profile template is shared for both a Register’s alternates profile as well as a class instance item’s alternates profile. In any case, since a RegisterRenderer class and a Custom Renderer class both inherit from the base class Renderer, then they can both easily render the alternates profile by calling the base class’ pyldapi.Renderer.render_alternates_profile() method. One distinct difference is that pyLDAPI will handle the alternates profile automatically for a RegisterRenderer whereas a Custom Renderer will have to explicitly call the pyldapi.Renderer.render_alternates_profile().

Example usage for a Custom Renderer:

# context: inside a 'custom' Renderer class which inherits from pyldapi.Renderer

# this is an implementation of the abstract render() of the base class Renderer
def render(self):
    # ...
    if self.profile == 'alternates':
        return self.render_alternates_profile() # render the alternates profile for this class instance
    # ...
