Upgrading Weblate¶
Docker image upgrades¶
The official Docker image (see Installing using Docker) has all upgrade steps integrated. There are no manual step besides pulling latest version.
Generic upgrade instructions¶
Before upgrading, please check the current Software requirements as they might have
changed. Once all requirements are installed or updated, please adjust your
settings.py to match changes in the configuration (consult
settings_example.py for correct values).
Always check Version specific instructions before upgrade. In case you are skipping some versions, please follow instructions for all versions you are skipping in the upgrade. Sometimes it’s better to upgrade to some intermediate version to ensure a smooth migration. Upgrading across multiple releases should work, but is not as well tested as single version upgrades.
Примечание
It is recommended to perform a full database backup prior to upgrade so that you can roll back the database in case upgrade fails, see Backing up and moving Weblate.
Upgrade configuration file, refer to
settings_example.pyor Version specific instructions for needed steps.Upgrade database structure:
./manage.py migrate --noinput
Collect updated static files (mostly javascript and CSS):
./manage.py collectstatic --noinput
Update language definitions (this is not necessary, but heavily recommended):
./manage.py setuplang
Optionally upgrade default set of privileges definitions (you might want to add new permissions manually if you have heavily tweaked access control):
./manage.py setupgroups
If you are running version from Git, you should also regenerate locale files every time you are upgrading. You can do this by invoking:
./manage.py compilemessages
Verify that your setup is sane (see also Production setup):
./manage.py check --deploy
Restart celery worker (see Background tasks using Celery).
Version specific instructions¶
Upgrade from 2.x¶

Upgrading from Python 2 to Python 3¶
Примечание
Weblate will support Python 2 util 4.0 release currently scheduled on April 2020. This is in line with Django dropping support for Python 2.
Weblate currently supports both Python 2.7 and 3.x. Upgrading existing installations is supported, but you should pay attention to some data stored on the disk as it might be incompatible between these two.
Things which might be problematic include Whoosh indices and file based caches. Fortunately these are easy to handle. Recommended upgrade steps:
Backup your Translation Memory using
dump_memory:./manage.py dump_memory > memory.json
Upgrade your installation to Python 3.
Delete Translation Memory database
delete_memory:./manage.py delete_memory --all
Restore your Translation Memory using
import_memory../manage.py import_memory memory.json
Recreate fulltext index using
rebuild_index:./manage.py rebuild_index --clean --all
Cleanup avatar cache (if using file based) using
cleanup_avatar_cache../manage.py cleanup_avatar_cache
It is recommended to throw away your caches.
Migrating from other databases to PostgreSQL¶
If you are running Weblate on other dabatase than PostgreSQL, you should migrate to PostgreSQL as that will be the only supported database backend in the 4.0 release. The following steps will guide you in migrating your data between the databases. Please remember to stop both web and Celery servers prior to the migration, otherwise you might end up with inconsistent data.
Creating a database in PostgreSQL¶
It is usually a good idea to run Weblate in a separate database, and separate user account:
# If PostgreSQL was not installed before, set the master password
sudo -u postgres psql postgres -c "\password postgres"
# Create a database user called "weblate"
sudo -u postgres createuser -D -P weblate
# Create the database "weblate" owned by "weblate"
sudo -u postgres createdb -O weblate weblate
Configuring Weblate to use PostgreSQL¶
Add PostgeSQL as additional database connection to the settings.py:
DATABASES = {
'default': {
# Database engine
'ENGINE': 'django.db.backends.mysql',
# Database name
'NAME': 'weblate',
# Database user
'USER': 'weblate',
# Database password
'PASSWORD': 'password',
# Set to empty string for localhost
'HOST': 'database.example.com',
# Set to empty string for default
'PORT': '',
# Additional database options
'OPTIONS': {
# In case of using an older MySQL server, which has MyISAM as a default storage
# 'init_command': 'SET storage_engine=INNODB',
# Uncomment for MySQL older than 5.7:
# 'init_command': "SET sql_mode='STRICT_TRANS_TABLES'",
# If your server supports it, see the Unicode issues above
'charset': 'utf8mb4',
# Change connection timeout in case you get MySQL gone away error:
'connect_timeout': 28800,
}
},
'postgresql': {
# Database engine
'ENGINE': 'django.db.backends.postgresql',
# Database name
'NAME': 'weblate',
# Database user
'USER': 'weblate',
# Database password
'PASSWORD': 'password',
# Set to empty string for localhost
'HOST': 'database.example.com',
# Set to empty string for default
'PORT': '',
}
}
Create empty tables in the PostgreSQL¶
Run migrations and drop any data inserted into the tables:
python manage.py migrate --database=postgresql
python manage.py sqlflush --database=postgresql | psql
Dump legacy database and import to PostgreSQL¶
python manage.py dumpdata --all --output weblate.json
python manage.py loaddata weblate.json --database=postgresql
Migrating from Pootle¶
As Weblate was originally written as replacement from Pootle, it is supported
to migrate user accounts from Pootle. You can dump the users from Pootle and
import them using importusers.
