Changelog

1.1.1 2021-01-15

  • Add support for Rails 6.1 #108
  • Fix statement cache for has_many through relations #103

1.1.0 2020-08-06

1.0.4 2019-10-30

  • Fix bug introduced in 1.0.3 for delete when table is reference or not distributed

1.0.3 2019-10-28

  • Ensure that when using object.delete, we set the tenant

1.0.2 2019-09-20

  • Compatibility with rails 6
  • Remove support for rails 4.0 and 4.1
  • Fix bug when multiple databases are used

1.0.1 2019-08-27

  • Ensure current tenant is present before adding tenant id filter in DatabaseStatements

1.0.0 2019-07-05

  • Fix RETURNING id for distributed tables with no primary key
  • Include fix for partial select described in issue #34.
    • When doing a partial select without the tenant like Project.select(:name).find(project.id) it would raise ActiveModel::MissingAttributeError (missing attribute: tenant_id)

0.11.0 2019-06-12

  • Fix queries with joins by including the tenant column when current tenant isn't set
    • A common use case is having a filter on the tenant, but MultiTenant.with isn't used like Project.where(account_id: 1).eager_load(:categories). This version fixes the ORM call to include in the join: "project_categories"."account_id" = "projects"."account_id"

0.10.0 2019-05-31

  • Add MultiTenant.without to remove already set tenant context in a block #45 Jackson Miller
  • Fix uninitialized constant X::ActiveRecord::VERSION #42 vollnhals
  • Fix find and find_by caching issues
    • This builds on work by multiple contributors, and fixes issues where the tenant_id would be cached across different tenant contexts for find and find_by methods. This issue was only present with prepared statements turned on
    • Note that the mechanism to solve this is slightly different for Rails 4 and 5:
    • Rails 4: Disable any caching for find and find_by methods
    • Rails 5: Explicitly add the current_tenant_id into the cache key
    • This also ensures that we test both prepared statements on and off on Travis
  • Added method to ensure that the current tenant is loaded #49 Stephen Bussey
    • This is ideal for fully utilizing the ActiveRecord extensions, as they only take effect when the current tenant is not an ID
  • Update loofah and rack to fix security warnings
    • Note that loofah is not a direct dependency of the libary, so this only applies when running the test suite
  • Remove monkey patch that previously disabled referential integrity (DISABLE/ENABLE TRIGGER ALL) #53 Rémi Piotaix
    • This was required for Citus compatibility, but the issue has been fixed in Citus for over a year (citusdata/citus#1080)

0.9.0 2018-06-22

0.8.1 2017-10-06

  • Cast attribute name to a string to avoid double applying tenant clause Ben Olive
  • Allow bulk delete/update with subqueries on joins Kyle Bock

0.8.0 2017-08-16

  • Significant improvements and simplifications of query rewriting
    • Big thanks to Kyle Bock and Ben Olive for (re-)writing this code and verifying it works well
    • This fixes caching issues across multiple MultiTenant.with { } blocks when interacting with the Rails statement cache
  • Drop support for Rails 3.2
    • The arel version used in Rails 3.2 has caused more trouble than its worth - it seems less troublesome to ask any users of this library to upgrade to at least Rails 4.0

0.7.0 2017-07-18

  • Switch back to Relation-based mechanism of hooking into ActiveRecord (this resolves issues for simple queries that didn't get rewritten)
  • Query rewriter improvements
    • Handle OUTER JOIN correctly
    • Correctly rewrite sub-selects
  • Model tenant method: Only return cached object if not loaded
  • Fix support for inherited model classes that only have multi-tenant on a higher level object Aaron Severs #13
  • Sidekiq middleware: Don't automatically perform a find for the tenant object for every job Scott Mitchell #14
  • Fix automatic inverse of on singular associations Kyle Bock #15
  • Fix bug that prevents fast truncate from running Kyle Bock #17

0.6.0 2017-06-09

  • Query rewriter
    • Change hook from per-relation to be pre-SQL statement thats being output
      • This should resolve issues where we added conditions in the wrong place
    • Use table name to model klass registry
  • Improve tests for activerecord-multi-tenant
    • Use lower shard count to speed up tests
    • Drop database cleaner dependency

0.5.0 2017-05-08

  • Write-only mode that enables step-by-step migrations
  • Add tenant_id to queries using rewrite instead of default_scope/unscoped Ben Olive
  • Query monitor that warns you about missing tenant_id
  • Helper for fast truncation
  • Sidekiq middleware

0.4.1 2017-03-23

  • Allow use outside of Rails, e.g. when using Sinatra with ActiveRecord @nathanstitt #5

0.4.0 2017-03-22

  • Infer multi_tenant setting from parent classes @webandtech #6
  • Remove use of global tenant klass variable @webandtech #6
  • Support passing ID values to MultiTenant.with directly @webandtech #6
    • This effectively deprecates with_id, but we'll keep it around for now
  • Remove unnecessary validation for invalid belongs_to association

0.3.4 2017-02-22

  • Expand with_lock workaround to cover lock! as well
  • Enable trigger workaround on Rails 5 as well, otherwise it fails silently
  • Tests: Switch to database cleaner truncation strategy to avoid multi-shard transactions

0.3.3 2017-02-21

  • Avoid warning about multi-column primary keys with Rails 5 #2
  • Fix odd bind errors for has_one/has_many through
  • Add MultiTenant.current_tenant_id= helper method

0.3.2 2017-02-16

  • Support blocks passed into the unscoped method (this fixes reload, amongst other issues)
  • Make with_lock work by adding workaround for Citus #1236 (SELECT ... FOR UPDATE is not router-plannable)

0.3.1 2017-02-13

  • Rails 5 API controller support @mstahl #4
  • Citus 6.1 compatibility

0.3.0 2016-12-30

  • Fix issue with callbacks having TenantIdWrapper instead of the actual object

0.2.1 2016-12-29
