declarative translation in List and Show views

[EBIHARA, Yuichiro]

Hi,

My model has a "status" column to store the status of approval.
The value can be one of "A" for approved, "R" for rejected and "P" for pending.
I'd like to let users choose a value from a select list and I added
the following lines in my controller.

config.columns[:status].form_ui = :select
config.columns[:status].options = {:options => [["Approved", "A"],
["Rejected", "R"], ["Pending", "P"]]}

It works in Update view as I expect.
Now I want the translated string ("Approved", "Rejected", "Pending")
to be displayed in List and Show views, too.
Is it possible to implement it "declaratively", instead of using field override?

Thanks in advance,

ebi

Hi,

I usually do that:

class MyModel
  STATUSES = [
    [human_attribute_name('approved'), 'A'],
    [human_attribute_name('rejected'), 'R'],
    [human_attribute_name('pending'), 'P']
  ]
end

class MyController
  active_scaffold do |config|

    config.columns[:status].form_ui = :select

    config.columns[:status].options = MyModel::STATUSES
  end
end

module MyControllerHelper
  def status_column record
    MyModel.human_attribute_name record.status
  end
end

But I has too much code and I don't know another way. This works like a enum field, I never thinked about simplify that before.

I will wait for other's users suggestions.

Gabriel,

Thank you for your reply.
Your idea looks better than my current implementation.

By the way, I have validates_inclusion_of command in my model as follows.

class MyModel < ActiveRecord::Base
  validates_inclusion_of :status, :in => ["A", "R", "P"]
end

If I defined STATUSES as Gabriel proposes, it would be no longer DRY.
Does anyone have a good idea to keep things DRY?

Thanks,

ebi

Change :in => ["A", "R", "P"] with STATUSES.collect{|string, key| key}

@Yuichiro

I made a small helper for AS to solve this. I will convert this into a plugin soon, but for now this could be useful.

You need to create a initializer file with this content: http://pastie.org/private/7bwdwqwc7jemz1aharpa

Then you use like I said:

class Model
  VALUES = [
    [human_attribute_name('one'), 'one'],
    [human_attribute_name('two'), 'two'],
  ].freeze
end

class Controller
  active_scaffold do |config|
    config.columns[:name].form_ui = :enum
    config.columns[:name].options = Model::VALUES
  end
end


And you dont need to create a helper to parse the column. The helper was I made will do it using the options value.

I made the plugin, look here: http://github.com/sobrinho/as_enum_column
