Sean Griffin a45363a2fb Always prefer class types to query types when casting group 
When `group` is used in combination with any calculation method, the
resulting hash uses the grouping expression as the key. Currently we're
incorrectly always favoring the type reported by the query, instead of
the type known by the class. This causes differing behavior depending on
whether the adaptor actually gives proper types with the query or not.
After this change, the behavior will be the same on all adaptors -- we
see if we know the type from the class, fall back to the type from the
query, and finally fall back to the identity type.

Fixes #25595

Raw Blame History

  • Using group with an attribute that has a custom type will properly cast the hash keys after calling a calculation method like count. Fixes #25595.

    Sean Griffin

  • Fix the generated #to_param method to use omission: '' so that the resulting output is actually up to 20 characters, not effectively 17 to leave room for the default "...". Also call #parameterize before #truncate and make the separator: /-/ to maximize the information included in the output.

    Fixes #23635.

    Rob Biedenharn

  • Ensure concurrent invocations of the connection reaper cannot allocate the same connection to two threads.

    Fixes #25585.

    Matthew Draper

  • Inspecting an object with an associated array of over 10 elements no longer truncates the array, preventing inspect from looping infinitely in some cases.

    Kevin McPhillips

  • Removed the unused methods ActiveRecord::Base.connection_id and ActiveRecord::Base.connection_id=.

    Sean Griffin

  • Ensure hashes can be assigned to attributes created using composed_of. Fixes #25210.

    Sean Griffin

  • Fix logging edge case where if an attribute was of the binary type and was provided as a Hash.

    Jon Moss

  • Handle JSON deserialization correctly if the column default from database adapter returns '' instead of nil.

    Johannes Opper

  • Introduce ActiveRecord::TransactionSerializationError for catching transaction serialization failures or deadlocks.

    Erol Fornoles

  • PostgreSQL: Fix db:structure:load silent failure on SQL error.

    The command line flag -v ON_ERROR_STOP=1 should be used when invoking psql to make sure errors are not suppressed.

    Example:

    psql -v ON_ERROR_STOP=1 -q -f awesome-file.sql my-app-db

    Fixes #23818.
