django-dynamic-template 0.2.0

Django app for content-type–scoped dynamic templates with NamedID slugs

django-dynamic-template

Django app for content-type–scoped dynamic templates: store DTL fragments in the database, address them with a named_id slug (django-namedid), inject optional related querysets and a structured object dict into each fragment.

Requirements

• Python ≥ 3.10
• Django ≥ 3.2
• django-namedid (declared in pyproject.toml; VCS pin until stable wheels are available)

Installation

From the repository root (editable install recommended for local work):

pip install -e .

Add the app and dependencies you need:

INSTALLED_APPS = [
    # ...
    "dynamic_template",
]

Optional: django-boosted (admin preview), django-richtextfield (TinyMCE-style widget) — see pyproject.toml [project.optional-dependencies] dev.

Concepts

Piece	Role
DynamicTemplate	label, content_type, named_id, template (richtext), plus model_fields, annotate_fields, fields shaping object in the fragment
DynamicRelationContext	Related queryset (manager + filters), same three JSON fields per row; rows are tuples of dicts in the fragment
{% dyntpl %}	Loads a template by named_id, merges context, evaluates relation contexts, then replaces object with a plain dict

• model_fields: ORM column names (empty → all concrete fields on the model).
• annotate_fields: list of annotation aliases already on the queryset / instance — this app does not call .annotate(); your manager or view must provide them.
• fields: extra Python names resolved with getattr (@property, class attributes, methods).

Filters on relations: filter_spec (resolved from object + template context) and filter_literal (static ORM kwargs). See docs/purpose.md for full detail.

Template tag

{% load dyntpl %}

{% dyntpl "my-block-named-id" %}
{% dyntpl tpl_id obj=article %}
{% dyntpl tpl_id ctype=Product obj=product %}

• obj=: must match the template’s content_type.
• ctype=: disambiguates when the same named_id exists for several models.
• Other keyword arguments are merged into the inner fragment context.

In the fragment, use {{ object.name }}, {% for row in article %}{{ row.title }}{% endfor %}, {{ rows|length }} (not .count on querysets).

Settings (optional)

# Import path to a widget class for the template field in admin
DYNAMIC_TEMPLATE_RICHTEXT_WIDGET = "djrichtextfield.widgets.RichTextWidget"

Development

pytest

pyproject.toml sets DJANGO_SETTINGS_MODULE=tests.settings and pythonpath=["src"].

Apply migrations for the bundled test project:

PYTHONPATH=src DJANGO_SETTINGS_MODULE=tests.settings python manage.py migrate
