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
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
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
python manage.py dumpdata > wirecloud.backup
For restoring the backup you only have to run the
loaddata command, using a clean database:
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
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 rebuild_index python manage.py collectstatic --noinput
> **NOTE**: Remember to run those commands using the user serving wirecloud (e.g. `su wirecloud`)
- 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 1.2.x to 1.3.x¶
WireCloud 1.3 has done minor changes to the search index schemas, so you have to update search indexes by running the
rebuild_index command. Also, there are new versions of the predefined dashboards and widgets, so you have use to the
populate command to update them.
From 1.1.x to 1.2.x¶
WireCloud 1.2 has moved from directly use Whoosh for using search indexes to use Haystack for managing search indexes.
Although Haystack has support for using Whoosh as search index backend, the schema used for the search indexes are
different. You have to incorporate Haystack configuration into your
settings.py file and rebuild them by running the
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 use to the
IdM integration has migrated from
social-auth-app-django (see this link
for more info about this change)
