Banana specific Django View Mixins

To fit our specific requirements we created Django View Mixins that extend the default behavior. They are used in various views in the banana app.

The mixins

class banana.views.mixins.DatasetMixin

Mixin view that adds the ‘dataset’ request variable to the context.

class banana.views.mixins.FluxViewMixin

Mixin view that adds the ‘flux_prefix’ request variable to the context.

class banana.views.mixins.HybridTemplateMixin

Assigns a default template_name, and checks the request for a format.

If the format specified in the querystring is json or csv, this will change the content_type and template_name accordingly.

If template name is not explicitly set, we assign one based on the object or model in the view. We derive the template path as:

<app_label>/<object_name.lower()><template_name_suffix><extension>

where template_name_suffix is something like ‘_list’ or ‘_detail’ (inherited from the Django standard class views) e.g.:

banana/extractedsource_list.html

banana/extractedsource_detail.html

class banana.views.mixins.SortListMixin

View mixin which provides sorting for ListView.
