From c09a4fd23d7d52552132edde7ad155f366c560b8 Mon Sep 17 00:00:00 2001 From: Tongfei Gao Date: Sat, 18 May 2019 20:58:22 +0800 Subject: Allow specify fixtures to be ignored Allow specifying what fixtures can be ignored by setting `ignore` in fixtures YAML file: # users.yml _fixture: ignore: - base base: &base admin: false introduction: "This is a default description" admin: <<: *base admin: true visitor: <<: *base In the above example, "base" fixture will be ignored when creating users fixture. This is helpful when you want to inherit attributes and it makes your fixtures more "DRY". --- activerecord/CHANGELOG.md | 4 ++ activerecord/lib/active_record/fixture_set/file.rb | 6 ++- activerecord/lib/active_record/fixtures.rb | 45 ++++++++++++++++++++-- activerecord/test/cases/fixtures_test.rb | 27 +++++++++++++ activerecord/test/fixtures/other_books.yml | 26 +++++++++++++ activerecord/test/fixtures/parrots.yml | 8 +++- 6 files changed, 111 insertions(+), 5 deletions(-) create mode 100644 activerecord/test/fixtures/other_books.yml (limited to 'activerecord') diff --git a/activerecord/CHANGELOG.md b/activerecord/CHANGELOG.md index 366032c734..7f2071189b 100644 --- a/activerecord/CHANGELOG.md +++ b/activerecord/CHANGELOG.md @@ -1,3 +1,7 @@ +* Allow specifying fixtures to be ignored by setting `ignore` in YAML file's '_fixture' section. + + *Tongfei Gao* + * Make the DATABASE_URL env variable only affect the primary connection.
