django-templateselector ======================= :author: Keryn Knight :version: 0.2.5 .. |travis_stable| image:: https://travis-ci.org/kezabelle/django-template-selector.svg?branch=0.2.5 :target: https://travis-ci.org/kezabelle/django-template-selector .. |travis_master| image:: https://travis-ci.org/kezabelle/django-template-selector.svg?branch=master :target: https://travis-ci.org/kezabelle/django-template-selector ============== ====== Release Status ============== ====== stable (0.2.5) |travis_stable| master |travis_master| ============== ====== .. contents:: Sections :depth: 2 What it does ------------ Provides a new model field, ``fields.TemplateField`` which allows for selection of a specific `Django`_ template using a nice form field (``fields.TemplateChoiceField``) and a nicer widget (``widgets.TemplateSelector``) than the standard ``<select>`` dropdown. Example ^^^^^^^ Below is a screenshot of the admin widget, without any thumbnails set up for each template, because I'm too lazy for that. .. image:: https://raw.github.com/kezabelle/django-template-selector/master/screenshot.png :alt: Example Use case -------- Imagine you have a ``Page`` model, and you want to allow admins or page authors to choose from a range of templates for the page to use, you could do this:: from django.db import models from templateselector.fields import TemplateField class MyPage(models.Model): title = models.CharField(max_length=100) # ... template = TemplateField(match='^myapp/mypage/layouts/.+\.html$') which would allow them to select any HTML file Django could find in the appropriate directory. Available functionality ----------------------- These fields are really the only public API. There's obviously other stuff, if you care to rummage around. ``TemplateField`` ^^^^^^^^^^^^^^^^^ Extends CharField, and requires a ``match`` argument which ought to be a string version of a regular expression. The ``match`` will be used to filter the possible choices. Optionally also takes a ``display_name`` argument, which is a callable (or ``dotted.string.path.to.one``) that takes a given string (the selected template path) and returns a nice name for it. The nice name is available as ``get_<fieldname>_display``, `for consistency with Django`_ The default form field for ``TemplateField`` is ... ``TemplateChoiceField`` ^^^^^^^^^^^^^^^^^^^^^^^ Has the same arguments as ``TemplateField``, and can be used independently in all forms if you want to not use the model field. The form field, when rendered with the ``TemplateSelector`` widget, will try and show a preview image for each template, by attempting to load a ``100W x 120H`` image from your staticfiles. Given a template name of ``path/to/template.htm`` it will try and load ``path/to/template.htm.png`` prefixed by whatever your ``STATIC_URL`` is. If no file exists, a placeholder image is shown as a fallback. Both this and the ``TemplateField`` make use of... ``nice_display_name`` ^^^^^^^^^^^^^^^^^^^^^ This function is the default callable for the ``display_name`` arguments on the ``TemplateField`` and ``TemplateChoiceField``, it tries to provide some flexibility and sensisble defaults; specifically: * If your project defines a ``TEMPLATESELECTOR_DISPLAY_NAMES`` setting which is a dictionary like ``{'path/to/template.html': "my awesome template"}`` then the name ``"my awesome template"`` will be shown by preference. * If not set, or no key match is found, the function will take the *file name* (not the path!) without *any extension* and will attempt to make a pretty, readable name of it by replacing most non-alphabet characters with spaces, so the template ``test/app/hello_world.html`` would become ``Hello world`` Supported Django versions ------------------------- The tests are run against Django 1.11 on Python 2.7, and 3.5. The widget uses the Django 1.11 template-based-rendering, so won't work on previous versions. Possibly it'll just default back to a normal radiobox? I dunno. Installation and usage ---------------------- Installation ^^^^^^^^^^^^ You can use `pip`_ to install the ``0.2.5`` version from `PyPI`_:: pip install django-templateselector==0.2.5 Or you can grab it from `GitHub`_ like this:: pip install -e git+https://github.com/kezabelle/django-template-selector.git#egg=django-template-selector Configuration ^^^^^^^^^^^^^ To get the ``TemplateSelector`` widget to display correctly, you *will* need to add ``templateselector`` to your project's ``INSTALLED_APPS``. You may also wish to configure ``TEMPLATESELECTOR_DISPLAY_NAMES = {}`` to provide nice names (see `nice_display_name`_) Usage ^^^^^ For using the `TemplateField`_, try something like this:: from django.db.models import Model from templateselector.fields import TemplateField class MyPage(models.Model): template = TemplateField(match='^myapp/mypage/layouts/.+\.html$') For using the `TemplateChoiceField`_ without using the Model field, you'd do something like:: from django.forms import Form from templateselector.fields import TemplateChoiceField class MyForm(Form): field = TemplateChoiceField(match="^myapp/[0-9]+.html$") To get the widget's CSS, don't forget to use ``{{ form.media }}`` in your template! Altering the widget choice size ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If you'd like to modify the dimensions used for each option in the widget (eg: you have landscape template thumbnails instead of portrait) you'll need to override the following CSS classes:: .templateselector-list-item { width: ???; } .templateselector-label input { top: ???; } .templateselector-thumb { width: ???; height: ???; } You can probably use the ``#id_FIELDNAME`` for a given field to provide the necessary specificity. You may need to provide a wrapper element if you re-use the same model/form attribute name (eg: ``{{ myform.selected_file }}``) for multiple things with different dimensions::  <div class="myform-wrapper">{{ myform.selected_file }}</div>  <div class="myapp-wrapper">{{ mymodelform.selected_file }}</div> Running the tests ^^^^^^^^^^^^^^^^^ If you have a cloned copy, you can do:: python setup.py test If you have tox, you can just do:: tox Running the demo ^^^^^^^^^^^^^^^^ A barebones demo is provided. It assumes you're using something like `virtualenv`_ and `virtualenvwrapper`_ but you can probably figure it out otherwise:: mktmpenv --python=`which python3` pip install -e git+https://github.com/kezabelle/django-template-selector.git#egg=django-templateselector Then probably:: cd src/django-templateselector python demo_project.py runserver The index page ``/`` will show you a normal version of the selection widget, while ``/admin/tests/mymodel/add/`` will show the slightly customised version for the standard `Django`_ admin.

One day I'll get sdist working again! 0.2.2 ^^^^^^ * |META| Still trying to master automatic deployment from Travis. No functionality change since ``0.2.0`` 0.2.1 ^^^^^^ * |META| Automatic deployment of new releases from Travis mostly worked, but the ``sdist`` is in poor shape (see commit ``44ad2a1542f2f61a73de84e0f7213bccfdb6f265``) so I've disabled that for now. Wheels are better anyway, right? No functionality change since ``0.2.0`` 0.2.0 ^^^^^^ * |FIX| prevent the "same" template showing up more than once in the widget, which wouldn't be possible when using ``get_template`` (`#1`_) * |NEW| If the form field (``TemplateChoiceField``) has only **one** valid template option, and the form is unbound (ie: its an **add** form or whatever) then pre-select the valid choice. Only happens if the field has ``required=True`` * |NEW| using the ``get_<fieldname>_display`` as a value in a ```ModelAdmin.list_display`` will now allow for sorting by the underlying value in the database. (`#2`_) * |NEW| if the ``<fieldname>`` is used as part of a ``ModelAdmin.list_filter`` it will show the nice display names of any used templates, rather than their internal path representation. (`#3`_) 0.1.1 ^^^^^^ * |META| First release on PyPI. 0.1.0 ^^^^^ * |META| Initial development. .. |FIX| replace:: **BUGFIX:** .. |NEW| replace:: **FEATURE:** .. |META| replace:: **MISC:** .. _#1: https://github.com/kezabelle/django-template-selector/issues/1 .. _#2: https://github.com/kezabelle/django-template-selector/issues/2 .. _#3: https://github.com/kezabelle/django-template-selector/issues/3 .. _system check: https://docs.djangoproject.com/en/stable/topics/checks/
