database
|
|
|
|
*Sean Griffin*
|

*Grey Baker*, *Norberto Lopes*
|
|
|
|
* The flag `error_on_ignored_order_or_limit` has been deprecated in favor of
|
|
the current `error_on_ignored_order`.
|
|
|
|
*Xavier Noria*
|
|
|
|
* Batch processing methods support `limit`:
|
|
|
|
Post.limit(10_000).find_each do |post|
|
|
# ...
|
|
end
|
|
|
|
It also works in `find_in_batches` and `in_batches`.
|
|
|
|
*Xavier Noria*
|
|
|
|
* 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.
