Provides layout related code for use in Armstrong and Django projects.

arm_layout provides you with tools to help streamline displaying content from within your application.

To load the template tags, add the following line (generally at the top of your template):

{% load layout_helpers %}

Once you have loaded the layout_helpers, you can use the render_model template tag to display a given model like this:

{% render_model some_model "full_page" %}

some_model is a variable in your template that is a model instance and the string "full_page" is the name of your "layout". render_model looks for a template named layout/<app_label>/<model>/<layout>.html to determine what to use to display your model instance.

render_model goes one step further, however. It is smart enough to walk through the inheritance of the model to determine if there are any other models that have the layout that can be used. For example, if some_model was an instance of armstrong.apps.articles.models.Article which inherits from armstrong.apps.content.models.Content, render_model looks for the following templates, in this order:

["layout/articles/article/full_page.html",
 "layout/content/content/full_page.html", ]

You have access to the entire template context inside the full_page.html template. You also have a new variable called object which represents the model instance that you provided to render_model. That variable is only available inside the layout template and temporarily overrides any context variable called object. Once render_model is finished, it restores the original context.

You can install the latest release of armstrong.core.arm_layout using pip:

pip install armstrong.core.arm_layout

Make sure to add armstrong.core.arm_layout to your INSTALLED_APPS. You can add this however you like. This works as a copy-and-paste solution:

INSTALLED_APPS += ["armstrong.core.arm_layout", ]
