Forum: Rails I18n Internationalize a Array of strings

Hi, i have a model User. Inside this model i have an Array:
  JOB_CATEGORIES = ['Undergraduate student', 'Graduate student' ,
'Pre-doctoral student', 'Postdoctoral student','Asociate profesor',
'Assistant profesor', 'Research profesor', 'Technician']

Then i use this array in a view in a Drop down select In the user's edit
form.

How can i internalionalize this array?

Hi Andrés,

How about:

en:
  job_categories:
    undergraduate: Undergraduate student
    graduate: Graduate student
    predoctoral: Pre-doctoral student
    postdoctoral: Postdoctoral student
    associate_prof: Asociate professor
    assistent_prof: Assistant professor
    research_prof: Research professor
    technician: Technician


And in your model:

class Job < ActiveRecord::Base

  def translated_job_category
    I18n.t(job_category, :scope => :job_categories)
  end

end

In your helper:

module JobsHelper
  def job_categories
    I18n.t(:job_categories).map { |key, value| [ value, key ] }
  end
end

And in your view:

<%= f.select :job_category, job_categories %>


The helper method creates an array that the select-helper understands.
It saves shortened keys ("undergraduate", "graduate", etc) in the
database, as some sort of enumerable. Be sure to keep those the same
in all languages.

When you want to show which job category an object has, you can do
@job.translated_job_category to get the translated value back.

I hope this helps,

Iain

Worked almost all!!!

The drop down don't show the option that the user save SELECTED in the 
drop
down. This is my view:

<%= profile.select :job_category, job_categories, {:prompt =>
I18n.t("prompt_job_categories")} %>

Thanks

Probably because traslation key is a symbol, when user attr is a string, 
so:

 def job_categories
   I18n.t(:job_categories).map { |key, value| [ value, key.to_s ] }
 end

perfect.
