Rails 在与 datetime 相同的数据类型“period_end”上对多个模型进行排序

Question

So far I have this for the sorting

sets = Array.new
sets += current_user.experiences.period_end + current_user.educations.period_end
sets.sort! do |current_user.experiences, current_user.educations| 
  current_user.experiences.period_end <==> current_user.educations.period_end
end

with this for the models

class Experience < ApplicationRecord
    attr_accessible :period_end

...
class EducationExperience < ApplicationRecord
    attr_accessible :period_end
...

And in the display on HTML I'd like to make an if statement to see if it's an experience or an education experience to change the color of the text.

Answer 1

You don't need to make if statements, just set proper class name to each container respectively. For example (using Slim):

div(class="#{model_name.class.to_s.underscore}")
 = model_name.desired_property

Your div will have class experience or education_experience respectively and you can adjust styles for them. Cheers
