Before this patch, column names could only be passed as a positional
argument when no other options were supplied:
remove_index :reports, :report_id
Passing column names positionally along with other options would fail:
remove_index :reports, :report_id, unique: true
# => ArgumentError: wrong number of arguments (given 3, expected 1..2)

* Allow column names to be passed to `remove_index` positionally along with other options.
|
|
|
|
Passing other options can be necessary to make `remove_index` correctly reversible.
|
|
|
|
Before:
|
|
|
|
add_index :reports, :report_id # => works
|
|
add_index :reports, :report_id, unique: true # => works
|
|
remove_index :reports, :report_id # => works
|
|
remove_index :reports, :report_id, unique: true # => ArgumentError
|
|
|
|
After:
|
|
|
|
remove_index :reports, :report_id, unique: true # => works

|
|
* Call `while_preventing_writes` directly from `connected_to`.
|
|
|
|
In some cases application authors want to use the database switching middleware and make explicit calls with `connected_to`. It's possible for an app to turn off writes and not turn them back on by the time we call `connected_to(role: :writing)`.
|
|
|
|
This change allows apps to fix this by assuming if a role is writing we want to allow writes, except in the case it's explicitly turned off.
