WireCloud provides a set of command line tools that can be used from the command line (manually or by scripts) on the folder of the WireCloud instance.
Adds one or more packaged mashable application components into the catalogue. At least one of the following flags:
- redeploy Replace mashable application components files with the new ones.
- users=USERS Comma separated list of users that will obtain access to the uploaded mashable application components
- groups=GROUPS Comma separated list of groups that will obtain access rights to the uploaded mashable application components
- public Allow any user to access the mashable application components.
$ python manage.py addtocatalogue --users=admin,ringo file1.wgt file2.wgt
Allows changing a user’s password. It prompts you to enter twice the password of the user given as parameter. If they both match, the new password will be changed immediately. If you do not supply a user, the command will attempt to change the password whose username matches the current user.
$ python manage.py changepassword ringo
Creates an empty organization. Once created, you will be able to add users to the associated group.
$ python manage.py createorganization
Creates a superuser account (a user who has all permissions). This is useful if you need to create an initial superuser account or if you need to programmatically generate superuser accounts for your site(s).
When run interactively, this command will prompt for a password for the new superuser account. When run non-interactively, no password will be set, and the superuser account will not be able to log in until a password has been manually set for it.
- --noinput Tells Django to NOT prompt the user for input of any kind. You must use --username with --noinput, along with an option for any other required field. Superusers created with --noinput will not be able to sign in until they're given a valid password.
- --username Specifies the login for the superuser.
- --email Specifies the email for the superuser.
The username and email address for the new account can be supplied by using the --username and --email arguments on the command line. If either of those is not supplied,
createsuperuser will prompt for it when running interactively.
$ python manage.py createsuperuser
Rebuilds Haystack indexes used by the search engine of WireCloud. See Haystack documentation for more details.
- --noinput If provided, no prompts will be issued to the user and the data will be wiped out.
$ python manage.py rebuild_index
Rebuilds Haystack indexes used by the search engine of WireCloud. To be removed in Wirecloud WireCloud v1.3.
- --noinput Tells Django to NOT prompt the user for input of any kind.
$ python manage.py resetsearchindexes
Creating WireCloud backups and restoring them¶
Create a backup of your instance folder. For example:
$ tar -cvjf wirecloud-backup.tar.bz2 -C /path/to/your/instance .
Create a backup of your database.
There are several ways for creating backups of the data stored in the database used by WireCloud, each of them with its advantages and disadvantages.
NOTE: Always stop WireCloud before creating a backup for ensuring data consistency.
Database backups using Django¶
Django provides the
loaddata commands that can be used for
creating and restoring backups. Those commands can be used independently of the
database engine used. Moreover, you can create those backups using a given
database engine and restore them using a different one. Run the following
command for creating a backup of your database using Django:
$ python manage.py dumpdata > wirecloud.backup
For restoring the backup you only have to run the
loaddata command, using a
$ python manage.py loaddata wirecloud.backup
NOTE: Backups created using
dumpdatacan only be restored using the same WireCloud version used for creating the backup. If you need to use a different version, restore the backup using the original version and then upgrade/downgrade it.
SQLite3 database backups¶
Creating a backup of a SQLite3 database is as easy as creating a copy of the file where the database is stored. The only thing to take into account is to stop WireCloud before creating the copy to avoid possible inconsistences.
The restoration procedure is as easy as the creation, you only have to make
WireCloud use the copied database file by editing the
settings.py file or by
moving the copied database file to the place expected by WireCloud.
NOTE: Take into account that this means that if you are making a full backup of your WireCloud instance, you don't need an extra step for backing up the database, this backup is already performed by backing up the instance directory.
PostgreSQL database backups¶
You can find more information about how to create PostgreSQL backups in this page. Basically, you have to run the following command:
$ pg_dump <dbname> > wirecloud.backup
Make sure WireCloud is not running before making the backup
You can restore the backup using the following command:
$ psql <dbname> < wirecloud.backup
Upgrading from previous versions¶
- Install the new version of WireCloud
Migrate the database and populate it with any new base component, rebuild the search indexes and collect the new static files by running the following commands:
$ python manage.py migrate $ python manage.py populate $ python manage.py resetsearchindexes $ python manage.py collectstatic --noinput
NOTE: Remember to run those commands using the user serving wirecloud (e.g.
Reload WireCloud (e.g.
$ service apache2 graceful)
You can determine your currently installed version using
$ wirecloud-admin --version 1.0.0
NOTE: It is strongly recommended to perform a full database backup before starting to migrate WireCloud to a new version.
From 1.0.x to 1.1.x¶
NGSI bindings (ngsijs) have been updated to
v1.0.2. This allows WireCloud to
directly use CORS requests when connecting to a
ngsi-proxy. The downside is
that WireCloud is unable to detect the version of ngsi-proxy used, so we had to
drop support for
v1.0.0 and below.
WireCloud 1.1 has changed the schema of the workspace search index, you have to
update this index by running the
resetsearchindexes command. Also, there are
new predefined dashboards, so you have to the
IdM integration has migrated from
social-auth-app-django (see this link for more info
about this change)
From 0.9.x to 1.0.x¶
NOTE: Support for Django 1.6 and Django 1.7 were removed in this version. Please, follow the steps described in the Upgrading to Django 1.7+ section before upgrading to WireCloud 1.0.
You can determine your currently installed version of Django by running the following command:$ django-admin --version 1.9.9
WireCloud 1.0 has changed some url definitions to remove some django warnings,
so you should update your
urls.py file. In particular, you have to change the
... # Catalogue url(r'^catalogue', include('wirecloud.catalogue.urls')), # Proxy url(r'^cdp', include('wirecloud.proxy.urls')), ...
... # Catalogue url(r'^catalogue/', include('wirecloud.catalogue.urls')), # Proxy url(r'^cdp/', include('wirecloud.proxy.urls')), ...
NOTE: If you plan to upgrade to Django 1.10, take into account that there were some deprecations regarding the syntax of the
url.pyfile. We have updated the
urls.pytemplate in WireCloud 1.0 to support Django 1.8-1.10 but if you created your WireCloud instance using an older version, you will have to update it manually. You can find the current template at github
WireCloud 1.0 has also added a search index for workspaces, you have to
initialize it by running the
resetsearchindexes command. The db should be
migrated before running this command.
$ python manage.py migrate $ python manage.py resetsearchindexes
WireCloud 1.0 added some predefined dashboards, so you have to create them by running the following command:
$ python manage.py populate
Also, WireCloud 1.0 provides support for real-time synchronization using web sockets, see the Enabling the real-time synchronization support section for instructions on how to enable it.
From 0.8.x to 0.9.x¶
IdM integration changes¶
FIWARE_PORTALShas been change to be empty by default. You can add the following code into your
settings.pyfile for obtaining the previous behaviour:
from wirecloud.fiware import FIWARE_LAB_PORTALS FIWARE_PORTALS = FIWARE_LAB_PORTALS
FIWARE_PORTALS documentation for more info.
Upgrading to Django 1.7+¶
Wirecloud 0.9.0+ adds support for Django 1.7-1.9 and next version of WireCloud (1.0) will drop support for Django 1.6 and Django 1.7. Moreover, at the time of releasing WireCloud 0.9.0, Django 1.6 and 1.7 were unsupported by the Django community.
The only thing to take into account when upgrading your WireCloud installation to use Django 1.7+ is that you need to migrate your db to Wirecloud 0.9.0 using Django 1.6 and South before upgrading to the new version of Django.
Once migrated the database and installed the new version of Django, run the following command for initializing the Django db migration framework:
$ python manage.py migrate --fake-initial
From 0.7.x to 0.8.x¶
WireCloud 0.8.x migrated FIWARE IdM code to use
python-social-auth instead of
django-social-auth due to the later being deprecated. Please, follow
these instructions if you are using the IdM integration:
pip install python-social-auth)
- Edit your
settings.pymaking the following changes:
urls.pyfile and replace:
url('', include('social.apps.django_app.urls', namespace='social'))
python-social-authmigrations (it uses the same dabase schema than
$ python manage.py migrate default --fake
Now you can remove django-social-auth :). E.g.:
$ pip uninstall django-social-auth
Migrate the user search index¶
WireCloud 0.8.2 updated the information stored in the user search index, so you should run the following command for updating this index:
$ python manage.py resetsearchindexes --indexes=user
From 0.6.x to 0.7.x¶
WireCloud 0.7.x adds support for using Whoosh indexes for searching, as WireCloud 0.6.x didn't use Whoosh, you need to run an extra step when migrating from 0.6.x to 0.7.x for creating a initial version of those indexes:
$ python manage.py resetsearchindexes
