4.0.0 (2021-01-10)

Changed

drop support for Ruby < 2.5, added support for Ruby 3.0
drop support for Rails < 5.0, added support for Rails 6.1
#398 - Predicate methods have been removed. (how to upgrade)
[#412][] - Filters will now treat blank string values as nil (except string and symbol). (how to upgrade)
#392 - Integer parsing now defaults the base to 10. (how to upgrade)
The inputs method now returns an ActiveInteraction::Input instead of a hash. The ActiveInteraction::Input class still responds to all hash methods.
The object and record filters now only accept an instance of the correct class type or a subclass of the correct class. They no longer allow you to check for included modules. (how to upgrade)
The interface filter will now look for an ancestor of the value passed based on the name of the interface or the value passed in the from option.
The InvalidClassError has been replaced by InvalidNameError.
When introspecting an array filter, the inner filter is referenced by :'0' instead of the singularized version of the array filter name.

Added

Implicit coercion of types are now supported in filters (e.g. to_str, to_int, etc).
The interface and record filters, when used as an inner filter for an array, will have their from/class option set to a singularized version of the array filter name.

Upgrading

Predicate Methods

We've removed the predicate methods that were automatically generated for each input. They would return true if an input was not nil. They can be manually replaced with that same check.

# v3.8
class Example < ActiveInteraction::Base
  string :first_name

  validates :first_name,
    presence: true,
    if: :first_name?

  def execute
    # ...
  end
end

# v4.0
class Example < ActiveInteraction::Base
  string :first_name

  validates :first_name,
    presence: true,
    unless: 'first_name.nil?'

  def execute
    # ...
  end
end

Blank Values Treated As `nil` For Filters

In an effort to improve form support, strings that are blank? will be converted into nil for all filters except string and symbol. Previously, blank strings would have cased :invalid_type errors but they'll now cause a :missing error which should be more form friendly. If the filter has a default, the blank string will cause the default to be used.

class Example < ActiveInteraction::Base
  integer :i
  boolean :b, default: false

  def execute
    [i, b]
  end
end

# v3.8
Example.run(i: '', b: '').errors.details
=> {:i=>[{:error=>:invalid_type, :type=>"integer"}], :b=>[{:error=>:invalid_type, :type=>"boolean"}]}

# v4.0
Example.run(i: '', b: '').errors.details
=> {:i=>[{:error=>:missing}]}

# v3.8
Example.run(i: 0, b: '').errors.details
=> {:b=>[{:error=>:invalid_type, :type=>"boolean"}]}

# v4.0
Example.run(i: 0, b: '').errors.details
=> {}

Example.run(i: 0, b: '').result
=> [0, false] # the default is used for `:b`

Integer Parsing Base Now 10

Integers are parsed using Integer. By default this meant that when strings were parsed, radix indicators (0, 0b, and 0x) were honored. Now we're defaulting the base to 10. This means all strings will be parsed as though they are base 10.

class Example < ActiveInteraction::Base
  integer :x

  def execute
    x
  end
end

# v3.8
Example.run!(x: '010')
# => 8

# v4.0
Example.run!(x: '010')
# => 10

If you want the old behavior that respected the radix you can pass 0 as the base.

- integer :x
+ integer :x, base: 0

With that change, we can see the radix is respected again.

# v4.0.0
Example.run!(x: '010')
# => 8

Object and Record Filter Changes

The object and record filters used to be able to check for included modules in addition to a class type. This has been removed. If you want any object that has a particular module included, you'll need to use the newly expanded interface filter.

3.8.3 (2020-04-22)

Fixed

[486][] valid? returns true if block not called and error added in execute around callback.

3.8.2 (2020-04-22)

Fixed

[479][] Composed interactions that throw errors now show a complete backtrace instead of ending at the run! of the outermost interaction.

3.8.1 (2020-04-04)

Fixed

The implementation for providing a failing interaction on InvalidInteractionError was a breaking API change. It now works without breaking the API.

3.8.0 (2020-02-28)

Added

#477 InvalidInteractionError now provides access to the failing interaction by calling interaction.
#476 Update given? to check for items in an array by passing an index.

3.7.1 (2019-03-20)

Fixed

#455 Switch to BigDecimal() to avoid warnings in Ruby 2.6.
#457 When using an after callback on execute the :if option does not see composed errors.

3.7.0 (2019-02-10)

Added

#454 Support for Rails 6.

Fixed

#435 Errors using the :message option were not properly merged.

3.6.2 (2018-08-21)

Fixed

#411 Cache the result of outcome validations. This also resolves duplicate callbacks on composed interactions.

3.6.1 (2017-11-12)

Fixed

#429 Pass details on translated detailed errors.

3.6.0 (2017-10-20)

Added

#422 A new record filter that accepts an object or calls a finder (e.g. find) for the value passed. This is particularly useful for ActiveRecord objects.
#420 A converter option on the object filter that allows the value passed to be manually converted into an object of the correct type.

3.5.3 (2017-09-28)

Fixed

#425 where given? did not properly handle string keys for hashes with nested content

3.5.2 (2017-06-08)

Fixed

#417 - detailed errors added to :base are now properly merged

3.5.1 (2017-05-11)

Fixed

#415: Reserved input names no longer error. Instead they are ignored. This fixes an issue with Rails 5.1 where :format was part of the params input sent to the interaction.

3.5.0 (2017-03-18)

Added

#408: given? can now check for values in nested hashes within the input

3.4.0 (2016-10-20)

Added

#387: Added an option to the integer filter to allow specification of a base when converting strings.

Fixed

#384: Fixed wrapping compose call in an ActiveRecord transaction.

3.3.0 (2016-09-13)

Added

#383: Allowed ActionController::Parameters as the input to ActiveInteraction::Base.run. Previously only Hash was allowed.

3.2.1 (2016-08-26)

Fixed

#377: Fixed a bug that allowed interactions to define inputs the conflicted with ActiveInteraction::Base's methods.
#370: Improved the French translation. Thanks, @voondo!

3.2.0 (2016-06-07)

Added

#365: Updated boolean filter to accept "on" for true and "off" for false. Thanks, @voondo!

Added

#362: Added translation for Brazilian Portuguese.

Fixed

#364: Fixed a bug that prevented callbacks from being called by composed interactions that failed.

3.1.0 (2016-04-01)

Added

#357: Allowed default lambdas to take an optional filter argument.

3.0.1 (2016-01-15)

Fixed

#349: Merging errors on :base with a message that was a String attempted to translate it.

3.0.0 (2016-01-13)

Changed

#333: Copy symbolic errors when using compose.

Removed

#344: Support for Ruby 1.9.3.
#346: Support for ActiveModel 3.2.

Upgrading

Symbolic errors from composed interactions are now copied to their equivalently named filters on the parent interaction. This can cause some odd cases as noted in the the README.

2.2.0 (2015-12-18)

Added

#336: Added frozen string pragma for Ruby 2.3.

Changed

#332: Changed default lambdas to be evaluated in the interaction's binding.

2.1.3 (2015-10-02)

Fixed

#303: Allowed ActiveRecord associations as inputs to array filters.

Changed

#304: Improved the error message for object filters when the class does not exist.

2.1.2 (2015-09-03)

Fixed

#298: Fixed a bug that raised exceptions when passing invalid nested values.

2.1.1 (2015-08-04)

Fixed

#296: Fixed a bug that silently converted invalid lazy default values to nil instead of raising an InvalidDefaultError.

2.1.0 (2015-07-30)

Added

#295: Added given? predicate method to see if an input was passed to run.

2.0.1 (2015-05-27)

Fixed

#286: Change file filter to check for rewind instead of eof?.
#289: Actually removed model filter, which was deprecated in v1.6.0.

2.0.0 (2015-05-06)

Changed

#250: Replaced symbolic errors with Rails 5-style detailed errors.
#269: Prevented proc defaults from being eagerly evaluated.
#264: Renamed model filter to object.
#213: Remove transaction support. Database transactions will need to be handled manually now.
#214: Results are returned from invalid outcomes.
#164: Changed the hash filter to use hashes with indifferent access.
#236: Changed the file filter to accept anything that responds to eof?.

Security

#215: Rather than symbolizing keys all hashes now use indifferent access. This takes care of potential but unlikely DoS attacks noted in #163.

Upgrading

Please read through the Changed section for a full list of changes.

The contents of the execute method are no longer wrapped in a transaction. You can manually add a transaction if you need it by using ActiveRecord::Base.transaction. We've also removed the transaction method since it no longer has a use.

# v1.6
class Example < ActiveInteraction::Base
  # This is the default.
  transaction true

  def execute
    # ...
  end
end

# v2.0
class Example < ActiveInteraction::Base
  def execute
    ActiveRecord::Base.transaction do
      # ...
    end
  end
end

Symbolic errors should now be added with add instead of add_sym. Additionally, you can view the errors with details instead of symbolic. This aligns with the direction Rails is taking.

# v1.6
class Example < ActiveInteraction::Base
  def execute
    errors.add_sym :base, :invalid
    errors.add_sym :base, :custom, '...'
  end
end
Example.run.errors.symbolic
# => {:base=>[:invalid,:custom]}

# v2.0
class Example < ActiveInteraction::Base
  def execute
    errors.add :base, :invalid
    errors.add :base, :custom, message: '...'
  end
end
Example.run.errors.details
# => {:base=>[{:error=>:invalid},{:error=>:custom,:message=>'...'}]}

In the hash filter we've stopped converting all inputs to symbols and instead we now convert the hash to a hash with indifferent access. This means hash keys will display as strings instead of symbols.

class Example < ActiveInteraction::Base
  hash :options,
    strip: false

  def execute
    options.keys
  end
end

# v1.6
Example.run!(options: { enable: true })
# => [:enable]

# v2.0
Example.run!(options: { enable: true })
# => ["enable"]

We added the ability to return results from invalid interactions. Setting the result to nil was unnecessary. The right way to check for validity is to use valid?. This change allows you to return something from an interaction even if there are errors. This can be very useful when updating an existing record.

class Example < ActiveInteraction::Base
  def execute
    errors.add(:base)
    'something'
  end
end

# v1.6
outcome = Example.run
outcome.valid?
# => false
outcome.result
# => nil

# v2.0
outcome = Example.run
outcome.valid?
# => false
outcome.result
# => "something"

When setting a default with a Proc is is no longer eagerly evaluated.

class Example < ActiveInteraction::Base
  boolean :flag,
    default: -> {
      puts 'defaulting...'
      true
    }

  def execute
    puts 'executing...'
  end
end

# v1.6
# defaulting...
Example.run
# executing...

# v2.0
Example.run
# defaulting...
# executing...
