Themes

With the django library themes, you are able to include a theme to your django app. It includes an menu-, navigation-, action- and bottombar.

Requirements

Python

You need to ensure that Pillow is available in your python environment.

Integration

Clone the library in your django application.

Configurations in your settings.py

Add the following line to the list INSTALLED_APPS:

    'themes.apps.ThemesConfig',

Configurations in your urls.py

Add the following imports at the top of urls.py,

from django.conf import settings
from django.conf.urls.static import static

the following line to the list urlpatterns:

    path('search/', <your-app>.views.search, name='search'),

and add this lines at the very end (after the definition of urlpatterns:

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Create a view for the search

Add a view to your views.py:

def search(request):
    logger.arning("Search not yet implemented...")
    return HttpResponse("Search not implemented...")

Settings

Replace the STATIC_URL definition in your settings.py with the following lines:

STATIC_ROOT = os.path.join(BASE_DIR, 'data', 'static')
STATIC_URL = 'static/'

MEDIA_ROOT = os.path.join(BASE_DIR, 'data', 'media')
MEDIA_URL = '/media/'

Collect static

Before the static data is available, you need to execute the command


## Usage
### Add a template
Before we can use the theme, we need to create a template. Here we use the file ```<your-app>/templates/app/page.html``` with the following contenet:

{% extends “themes/”|add:settings.page_theme|add:“/base.html” %}

{% block content %} {{ page_content|safe }} {% endblock content %}

In the block content is your content, which will be passed to the template by the variable ```page_content```.

### Use the template in your view
Now you need to adapt your view. Here is an example view using the theme.

from django.shortcuts import render from django.conf import settings

from themes import Context

def example(request, rel_path=“):

context = Context(request)      # needs to be executed first because of time mesurement
#
return render(request, 'app/page.html', context=context)

### Upload the logo
If you havn't created a user yet, you should do so with ```python manage.py createsuperuser ```.

Visit http://127.0.0.1:8000/admin and login with that user. Klick on *Settings* in the *Themes* section and then on the *Settings object (1)*.

Upload a logo with the Upload mechanism of *Page image:* and click *Save*.

### Create a context adaption
From this point on, you can see a blank themed page. With the adaption of the context variable, you are able to define the content of the 3 bars on the top and the page_content itself. The bottom bar will be defined in the django administration page (THEMES->Bottom bars->ADD BOTTOM BAR).

You need to adapt your view method. Add this between the context definition and the return statement:
context_adaption(
    context,
    request,
    title="Additional title",
    rel_path=rel_path,
    page_content=f"<h1> Dummy page</h1>The rel_path is {rel_path}",
)

Here as an example ```context.py```:

import inspect import logging

from django.conf import settings from django.utils.translation import gettext as _

from themes import empty_entry_parameters from themes import gray_icon_url from themes import color_icon_url

logger = logging.getLogger(settings.ROOT_LOGGER_NAME).getChild(name)

BACK_UID = “back” EDIT_UID = “edit” LOGIN_UID = “login”

def context_adaption(context, request, **kwargs):

caller_name = inspect.currentframe().f_back.f_code.co_name
logger.debug("The caller of context_adaption was %s", caller_name)
try:
    context.set_additional_title(kwargs.pop('title'))
except KeyError:
    pass    # no title in kwargs
menubar(context, request, caller_name, **kwargs)
navigationbar(context, request, caller_name, **kwargs)
actionbar(context, request, caller_name, **kwargs)
for key in kwargs:
    context[key] = kwargs[key]
logger.debug("context adapted: %s", repr(context))

def menubar(context, request, caller_name, **kwargs):

bar = context[context.MENUBAR]
bar.append_entry(
    LOGIN_UID,                                          # uid
    _('Settings'),                                      # name
    color_icon_url(request, 'settings.png'),            # icon
    '/app/dummy/settings/page',                         # url
    False,                                              # left
    kwargs.get("rel_path") == "dummy/settings/page"     # active
)
finalise_bar(request, bar)  # Show bar, if empty

def navigationbar(context, request, caller_name, **kwargs):

bar = context[context.NAVIGATIONBAR]
bar.append_entry(
    BACK_UID,                                           # uid
    _('Back'),                                          # name
    gray_icon_url(request, 'back.png'),                 # icon
    'javascript:history.back()',                        # url
    True,                                               # left
    False                                               # active
)
finalise_bar(request, bar)  # Show bar, if empty

def actionbar(context, request, caller_name, **kwargs):

bar = context[context.ACTIONBAR]
bar.append_entry(
    EDIT_UID,                                           # uid
    _('Edit'),                                          # name
    color_icon_url(request, 'edit.png'),                # icon
    '/app/dummy/edit/page',                             # url
    True,                                               # left
    kwargs.get("rel_path") == "dummy/edit/page"         # active
)
finalise_bar(request, bar)  # Show bar, if empty

def finalise_bar(request, bar):

if len(bar) == 0:
    bar.append_entry(*empty_entry_parameters(request))
