Description:

djangoodk 1.1.9

django-odk
Django data collection tool using ODK-collect mobile app.
Prerequisite

Django web site up and running
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

Run

$ pip install django-odk
$ python manage.py migrate
$ python manage.py createsuperuser


Add odk and odkdata to your INSTALLED_APPS settings

INSTALLED_APPS = (
...
'odk',
'odkdata',
)


Add LOCALE_PATHS and appropriate language_code in settings

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:


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


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


Convert xlsx file to xml XForm compatible file Thanks pyxform! If it is not working in production (504 Geteway timeout), xml (previously created from XLSForm Online) can be uploaded manually from admin site.


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


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!

Do not forget to add odkdata2 logger specifications in settings.py

Comments/Improvements welcome!
Investigate WQ Framework but I still don't see how to deploy offline forms on smartphone.
