Template tag for requesting views in templates (Django)

Project description

A template tag for making simulated GET requests to Django application view functions. The HTTP response can be displayed in the given template.

Variations of usage of viewssi:

{% viewssi %}
{% viewssi arg,arg2,kwarg=val %}
{% viewssi arg,arg2,kwarg=val as var %}
{% viewssi arg,arg2,kwarg=val get p1=v1,p2=v2 as var %}

The first argument is the path to a view function to call. If the view requires args and/or kwargs, pass them as the second token in the tag. args and the values of kwargs are resolved to template variables unless they are quoted.

The view doesn’t have to be exposed in a URL configuration. Essentially any function can be called that accepts one argument (the request) and returns a django.http.HttpResponse object.

You can pass a GET query string by including a get token in the tag followed by key=value pairs. Parameter values are also resolved to template variables unless they are quoted.

If the as <template-variable-name token of the tag is provided, the view’s response is assigned to the given template variable. Otherwise, the response content is returned in place.

When the response is assigned to a template variable, the http response is represented as a HttpResponseProxy object which contains a template-useable interface for fetching the response code, headers, and content. Examples:

{% ifequal response.status_code "200" %}
{{ response }}
{% endifequal %}

HttpResponseProxy behaves is a dict-like object. The http response headers are set as the dict items and their names are transposed for use in templates, i.e. ‘Content-type’ becomes ‘content_type’. For example:

{% ifequal response.content_type "text/html" %}
{% endifequal %}
