terra-opp 0.4.1

Observatoire Photographique des Paysages

Terralego Backend for OPP module

Requirements

• To handle pictures in templates, please install weasyprint requirement librairies https://weasyprint.readthedocs.io/en/stable/install.html#linux

First, create a data layer for observatory

./manage.py create_observatory_layer -n observatory

Then get the given primary key, for example 10.

Settings needed to be set

TROPP_OBSERVATORY_LAYER_PK=10  # replace by primary key given by command

VERSATILEIMAGEFIELD_RENDITION_KEY_SETS = {
  'terra_opp': [
    ('original', 'url'),
    ('full', 'thumbnail__1500x1125'),
    ('list', 'thumbnail__300x225'),
    ('thumbnail', 'thumbnail__180x120'),
  ]
}

AUTH_USER_MODEL = 'terra_accounts.TerraUser'

Media files

If your project is not using the default django storage, then you must define and set a url fetcher in order to tell weasyprint where to find your media files.

An example of url fetcher using media files from S3 storage :

from django.conf import settings
from terra_opp.renderers import django_url_fetcher


def custom_url_fetcher(url, *args, **kwargs):
   scheme = 'https' if settings.AWS_S3_SECURE_URLS else 'http'
   url_prefix = f"{scheme}://{settings.AWS_S3_CUSTOM_DOMAIN}"

   if url.startswith(url_prefix):
       url = url.replace(
           url_prefix,
           settings.AWS_S3_ENDPOINT_URL + settings.AWS_STORAGE_BUCKET_NAME
       )

   return django_url_fetcher(url, *args, **kwargs)

And then you must refer to this custom url fetcher in your settings. Example if your fetcher is define in custom/fetcher.py:

TROPP_URL_FETCHER = 'custom.fetcher.custom_url_fetcher'

0.4.1 / 2020-08-26

• Removing signals and doing all the logic in the related viewsets

0.4.0 / 2020-07-30

• Warning ! Breaking changes

  • Due to uniformity of storage usages, you need to use file:// schema in your template to access pictures
  • Deprecate defining observatory layer by name.
  • Now you need to define layer pk instead -> TROPP_OBSERVATORY_LAYER_PK.
  • Existing frontend applications should be fixed by TROPP_OBSERVATORY_LAYER_PK=1

• fix picture property

• fix prefetched data as list and not queryset

• fix restframework not listed in setup requirements

• Fix storage usage and make it working with weasyprint with default and custom storages

• add correct dependencies to handle JPG

• allow argument set layer name at creation

• dont block if observatory layer pk not defined, to let ability to create it

• block start without defined correct layer settings

• add and improve configuration checking

• add command to create point layer to used as observatory

• set defined observatory layer by pk and provide info to frontend to avoid expecting hardcoded pk=1 layer for tiles

• PK and corresponding endpoints are auto added to /api/settings to send dynamic configuration to frontend

• Storage bucket is not required anymore.
