djblets.features.templatetags.features¶

Template tags for working with features.

class IfFeatureNode(nodelist_enabled, nodelist_disabled, feature_id, extra_kwargs)[source]¶

Template node for feature-based if statements.

This works mostly like a standard {% if %} tag, checking whether the given feature is enabled and rendering the content between it and the else/end tags only if matching the desired state.

This supports a {% else %}, to allow rendering content if the feature does not match the desired state.

This is used by both the {% if_feature_enabled %} and {% if_feature_disabled %} tags.

render(context)[source]¶

Render the node.

This will determine if the feature is enabled or disabled, and render the appropriate list of nodes to a string.

Parameters

context (django.template.Context) – The context provided by the template.

Returns

The rendered content as a string.

Return type

unicode

if_feature_enabled(parser, token)[source]¶

Render content only if a feature is enabled.

This works mostly like a standard {% if %} tag, checking if the given feature is enabled before rendering the content between it and the else or end tags.

This supports a {% else %}, to allow rendering alternative content if the feature is disabled instead.

It also accepts additional keyword arguments that can be passed to Feature.is_enabled().

Parameters

• parser (django.template.Parser) – The parser being used to parse this template tag.

• token (django.template.Token) – The token representing this template tag.

Returns

The feature checker node to use for the template.

Return type

IfFeatureNode

Example

{% if_feature_enabled "my-feature" user=request.user %}
This will only render if the feature is enabled for the user.
{% else %}
This will only render if the feature is disabled for the user.
{% endif_feature_enabled %}

if_feature_disabled(parser, token)[source]¶

Render content only if a feature is disabled.

This works mostly like a standard {% if %} tag, checking if the given feature is disabled before rendering the content between it and the else or end tags.

This supports a {% else %}, to allow rendering alternative content if the feature is enabled instead.

It also accepts additional keyword arguments that can be passed to Feature.is_enabled().

Parameters

• parser (django.template.Parser) – The parser being used to parse this template tag.

• token (django.template.Token) – The token representing this template tag.

Returns

The feature checker node to use for the template.

Return type

IfFeatureNode

Example

{% if_feature_disabled "my-feature" user=request.user %}
This will only render if the feature is disabled for the user.
{% else %}
This will only render if the feature is enabled for the user.
{% endif_feature_disabled %}
