Since v4.0.13

Available in: v4.0.13 v4.1.16 v4.2.9 v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

assert_migration(relative, *contents, &block)

Asserts a given migration exists. You need to supply an absolute path or a path relative to the configured destination:

assert_migration "db/migrate/create_products.rb"

This method manipulates the given path and tries to find any migration which matches the migration name. For example, the call above is converted to:

assert_file "db/migrate/003_create_products.rb"

Consequently, assert_migration accepts the same arguments has assert_file.

Parameters

relative req
contents rest
block block
