Migrations

Django handles the migration of the database very well; however, there are various changes to SEED that may require some custom (manual) migrations. The migration documentation includes the required changes based on deployment and development for each release.

Version Develop

In order to support Redis passwords, the configuration of the Redis/Celery settings changed a bit. You will need to add the following to your local_untracked.py configuration file. If you are using Docker then you will not need to do this.

CELERY_RESULT_BACKEND = CELERY_BROKER_URL

If you are using a password, then in your local_untracked.py configuration, add the password to the CELERY_BROKER_URL. Your final configuration should look like the following in your local_untracked.py file

CELERY_BROKER_URL = 'redis://:[email protected]:6379/1'
CACHES = {
    'default': {
        'BACKEND': 'django_redis.cache.RedisCache',
        'LOCATION': CELERY_BROKER_URL,
    }
}

CELERY_RESULT_BACKEND = CELERY_BROKER_URL
CELERY_TASK_DEFAULT_QUEUE = 'seed-local'
CELERY_TASK_QUEUES = (
    Queue(
        CELERY_TASK_DEFAULT_QUEUE,
        Exchange(CELERY_TASK_DEFAULT_QUEUE),
        routing_key=CELERY_TASK_DEFAULT_QUEUE
    ),
)

Version 3.2.2

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Version 3.2.1

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Version 3.2.0

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Version 3.1.0

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Version 3.0.0

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Version 3.0.0-beta.0

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Version 2.22.0

  • Run ./manage.py migrate.

  • There is a Redis dependency update in this release that requires users and deployments to modify their settings' CACHES config.
    1. Update your dependencies with pip install -r requirements/base.txt
    2. Update the CACHES BACKEND property to django_redis.cache.RedisCache
    3. Update the CACHES LOCATION property to match the redis-py native URL notation for connection strings, including the redis protocol and database number. e.g. redis://localhost:6379/1

    Since the CELERY_BROKER_URL setting must also be in the same format, it may be helpful to configure that setting first and then reference it in the caches LOCATION parameter.

  • See the PR for an example migration.

Version 2.21.0

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Version 2.20.1

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Version 2.20.0

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.
  • There is a single long running migration related to importing census tract disadvantaged community data. This migration should take around 7 minutes to complete.

Version 2.19.0

  • Run ./manage.py migrate.
  • There is a new migration in this release that requires column names to be unique across organization, table_name, and is_extra_data. This migration will fail if there are duplicate column names. If you have duplicate column names, you will need to manually fix them in your database before running the migration. The following steps will help you identify and fix the duplicate column names:
    • Check the organization age to gauge the impact of the change. If it is a deprecated org, impact of the change will be low. Often this issue arose in older organizations when units were not part of the columns. The old mapping columns were not upserts with the units, so typically the columns impacted are the ones with units.
    • Query the seed_column table for the organization and column name displayed on the screen (e.g., organization_id = 300 and column_name = 'Source EUI (kBtu/ft2)'). If there is no table_name set, it is likely an import file column name and can easily be cleaned up without causing issues. In such cases, there will be two rows, and you want to keep the one with the units_pint column set.
    • More complex columns may require deleting or updating the column_id in the seed_columnmapping_* tables. If there is a foreign key constraint with seed_columnmapping_*, take note of the ID you want to remove and the ID you want it to be replaced with (preferably keep the one with units_pint).
    • If the constraint is on seed_columnmapping_column_raw:
      • The field should be an import file column (i.e., no table_name item). Query for the old column in seed_columnmapping_column_raw (e.g., column_name = <old_id>).
      • Replace the old ID with the new one. If it errors because it already exists, then the row can be deleted.
      • Return to the seed_column table and remove the old ID.
    • If the constraint is on seed_columnmapping_column_mapped:
      • The mapped column should have a table_name in the field. If not, it is likely an older organization.
      • If there is no table_name, remove the row from the seed_columnmapping_column_mapped table.
      • Return to the seed_column table and remove the old ID.

  • The migrations should work without additional support. Simply run ./manage.py migrate. There are no manual migrations needed.
  • Note the Important Note in Version 2.7.1 migration below which may require the need to run a "fake" migration

Version 2.7.1

  • There are no special migrations needed for this version. Simply run ./manage.py migrate.

Important Note:

If upgrading from < 2.7.0 to >= 2.7.1 you may encounter a failed migration with 0118_match_merge_link_all_orgs. This is expected if the database is several versions behind, and it effectively reorders migration 118 to run after all other migrations have completed to prepare your database to recognize properties and taxlots across multiple cycles. Run the following code manually to fully migrate:

  1. ./manage.py migrate --fake seed 0118_match_merge_link_all_orgs

  2. ./manage.py migrate

  3. ./manage.py shell

    from seed.lib.superperms.orgs.models import Organization
from seed.utils.match import whole_org_match_merge_link

for org in Organization.objects.all():
    whole_org_match_merge_link(org.id, 'PropertyState')
    whole_org_match_merge_link(org.id, 'TaxLotState')

Version 2.7.0

  • This migration will run a match/merge/pair/link method upon migration. Make sure to run the migration manually and not inside of the docker container using the ./deploy.sh script.
  • Make sure to backup the database before performing the migration.
  • Run ./manage.py migrate.

Version 2.6.1

  • The migrations should work without additional support. Simply run ./manage.py migrate. There are no manual migrations needed for the 2.6.1 release.

Version 2.6.0

Version 2.6.0 includes support for meters and time series data storage. In order to use this release you must first install TimescaleDB.

Docker-based Deployment

Docker-based deployments shouldn't require running any additional commands for installation. The timescaledb installation will happen automatically when updating the postgres container. Also, the installation of the extension occurs in a Django migration.

Ubuntu

sudo add-apt-repository ppa:timescale/timescaledb-ppa
sudo apt update
sudo apt install timescaledb-postgresql-10
sudo timescaledb-tune
sudo service postgresql restart

Max OSX

brew tap timescale/tap
brew install timescaledb
/usr/local/bin/timescaledb_move.sh
timescaledb-tune
brew services restart postgresql

Version 2.5.2

  • There are no manual migrations that are needed. The ./manage.py migrate command may take awhile to run since the migration requires the recalculation of all the normalized addresses to parse bldg correct and to cast the result as a string and not a bytestring.

Version 2.5.1

  • The migrations should work by simply running ./manage.py migrate. There are no manual migrations needed for the 2.5.1 release.

Version 2.5.0

Docker-based Deployment

  • Add the MapQuest API key to your organization.

  • On deployment, the error below is indicative that you need to install the extensions in the postgres database. Run docker exec <postgres_container_id> update-postgis.sh.

    django.db.utils.OperationalError: could not open extension control file "/usr/share/postgresql/11/extension/postgis.control": No such file or directory

  • If you are using a copied version of the docker-compose.yml file, then you need to change 127.0.0.1:5000/postgres to 127.0.0.1:5000/postgres-seed

Development

  • Delete your bower directory rm -rf seed/static/vendors.
  • Delete your css directory rm -rf seed/static/seed/css.
  • Remove these lines from local_untracked.py if you have them.
DEFAULT_FILE_STORAGE = 'django.core.files.storage.FileSystemStorage'
STATICFILES_STORAGE = DEFAULT_FILE_STORAGE
  • Run pip3 install -r requirements/local.txt.
  • Run npm install from root checkout of SEED.
  • If testing geocoding, then sign up for as a MapQuest Developer and create a new MapQuest Key.
  • Add the key to the organization that you are using in development.
  • Update your DATABASES engine to be django.contrib.gis.db.backends.postgis
DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': 'seeddb',
        'USER': 'seeduser',
        'PASSWORD': 'seedpass',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}
  • Run ./manage.py migrate
