Contentful provides a content infrastructure for digital teams to power content in websites, apps, and devices. Unlike a CMS, Contentful was built to integrate with the modern software stack. It offers a central hub for structured content, powerful management and delivery APIs, and a customizable web app that enable developers and content creators to ship digital products faster.
This library provides rendering capabilities for the RichText field type. It is recommended to be used alongside the Contentful Delivery SDK <https://www.github.com/contentful/contentful.py>.
By default this library will serialize RichText fields into it’s corresponding HTML representation. All behaviour can be overridden to serialize to different formats.

Installation
Install Contentful Rich Text Renderer from the Python Package Index:
pip install rich_text_renderer


Usage
Create a renderer:
from rich_text_renderer import RichTextRenderer

renderer = RichTextRenderer()
Render your document:
renderer.render(document)


Using different renderers
There are many cases in which HTML serialization is not what you want.
Therefore, all renderers are overridable when creating a rich_text_renderer.RichTextRenderer <rich_text_renderer.RichTextRenderer>.
Also, if you’re planning to embed entries within your rich text, overriding the 'embedded-entry-block' option is a must,
as by default it only does <div>str(entry)</div>.
You can override the configuration like follows:
renderer = RichTextRenderer({
'embedded-entry-block': MyEntryBlockRenderer
})
Where MyEntryBlockRenderer requires to have a render(self, node) method and needs to return a string, also it requires to be initialized with a dict containing mappings for all renderers.
An example entry renderer, assuming our entry has 2 fields called name and description could be:
from rich_text_renderer.base_node_renderer import BaseNodeRenderer

# BaseNodeRenderer implements the `__init__` method required.
class MyEntryBlockRenderer(BaseNodeRenderer):
def render(self, node):
entry = node['data']['target']

return "<div class='my-entry'><h3>{0}</h3><p><small>{1}</p></small></div>".format(
entry.name,
entry.description
)


Dealing with unknown node types
By default, this library will treat all unknown node types as errors and will raise an exception letting the user know which node mapping is missing.
If you wish to remove this behaviour then replace the None key of the mapping with a NullRenderer that returns an empty string, or something similar.
An example would be like follows:
class SilentNullRenderer(BaseNodeRenderer):
def render(node):
return ""

renderer = RichTextRenderer({
None: SilentNullRenderer
})
