• Smartphone or tablet with ODK-Collect installed
• XLSForm file with 3 tabs 'survey', 'choices', 'settings'

NEW from version 1.0.2 (xls2xml & create final model)

• Since most of Xforms are using geopoint, the database must be set up with vector geodatabase functionality: PostGIS, Oracle Spatial, SQLite/SpatiaLite
• Java Runtime Environment (JRE) installed $ sudo apt install default-jre for XForm validation used by xlsconv

Installation

LOCALE_PATHS = [os.path.join(BASE_DIR, 'odk', 'locale')]

LANGUAGE_CODE = 'en'
# translated LANGUAGE_CODE: fr

• Add appropriate AUTH_USER_MODEL in settings.py

AUTH_USER_MODEL = 'auth.user'

• For a more interactive app, configure logging as explained in Lincoln Loop and messages as explained in Django

• For logging, add odk and odkdata entry to loggers key of your logging file and adapt handlers according to yours.

    'loggers': {
        ...
        'odk': {
            'handlers': ['console', 'debugger', 'warning', 'error'],
            'level': 'DEBUG' if DEBUG else 'INFO',
            'propagate': False,
        },
        'odkdata': {
            'handlers': ['console', 'debugger', 'warning', 'error'],
            'level': 'DEBUG' if DEBUG else 'INFO',
            'propagate': False,
        },
    }

• Add is_odk_admin and is_odk_user property to your AUTH_USER_MODEL (django.contrib.auth.models file or specific accounts.models)

    @property
    def is_odk_admin(self):
        return self.groups.filter(name='odk-admin').exists()
    @property
    def is_odk_user(self):
        return self.groups.filter(name='odk-user').exists()        

• Add odk.urls to the main urls.py file:

urlpatterns = [
    ...
    path('odk/', include('odk.urls'), name='odk'),
]

• Add menu or buttons to access Available form

# bootstrap5 menu item example
<li><a class="dropdown-item" href="{% url 'odk:xform_list' %}">{% trans "ODK available forms" %}</a></li>

• Add menu or buttons to access Submitted form

# bootstrap5 menu item example
<li><a class="dropdown-item" href="{% url 'odk:xformsubmit_list' %}">{% trans "ODK submitted forms" %}</a></li>

Connect to the Django admin site

• create a group 'odk-admin' with create, read, update access on odk objects
• Associate this group to the appropriate users

Available form: Build, Upload, Convert, Create

Connect to django-odk => Available form => Add and follow 4 steps:

1. Build an XLSForm file with 3 tabs 'survey', 'choices', 'settings' Cfr documentation. Do not forget to add 'today' & 'username' fields in Survey tab!

2. Upload xlsx file (XForm) by clicking on 'Choose file' and Save

3. Convert xlsx file to xml XForm compatible file Thanks pyxform!

From this point, you are ready to go with form encoding on your smartphone!

Follow ODK instructions to configure the connexion to the server

Get, fill-in and submit data using ODK Collect

4. Create Model in odkdata to get submitted data in a model formatted like xlsx form. Thanks xlsconv!! Model creation is done into App odkdata with table name followed by _orig suffix when converted by xlsconv.

Submitted form

Go to Submitted form menu of your server to see submitted data in XML format. On record view, click on Insert button to insert submitted XML data into odkdata.models created on step 4 hereabove.

Several record insert is available through admin interface. Select appropriate records (ie: those without insert date) and choose Insert in odkdata model from action dropdown list and click on 'Send' button.

What next?

Create a new app in you project like odkdata2 with templates, views (importing odkdata.models info) and urls to manage display/map/export-xls/update/analyse submitted data from ODK-Collect!

Comments/Improvements welcome!

Investigate WQ Framework but I still don't see how to deploy offline forms on smartphone.
