Question

So i’ve got three models

"Text" has_many :statistics, :as => :loggable
"Document" has_many :statistics, :as => :loggable
"Statistic" belongs_to :loggable, :polymorphic => true
"Company" has_many "Documents"/"Texts"

now i want to get different restults, f.e.

• get the total count of statistic objects of all text/document objects of a company
• get the total count of statistic objects of all text/document objects of a company
  this month
• get the first five Texts/Documents of a company with the most statistic
  objects
• get the first five Texts/Documents of a company with the most statistic
  objects this month

this month is related to the creation date of the statistic object.

i really have no idea how to achieve this. i tried different things in the rails console but without luck.

company.texts
company.documents

any ideas how to do this?
thanks in advance. please leave a comment if something is unclear.

Answer 1

The first 2 are pretty simple.

get the total count of statistic objects of all text/document objects

Statistic.where(:loggable_type => "Text").where(:loggable_id => company.texts)

get the total count of statistic objects of all text/document objects this month

Statistic.where('created_at between ? and ?', 1.month.ago, Time.now).where(:loggable_type => "Text").where(:loggable_id => d.texts).count

get the first five Texts/Documents of a company with the most statistic objects

ids = Statistic.select("COUNT(*) AS count_all").where(:loggable_type => "Text").where(:loggable_id => company.texts).group(:loggable_id).order("count_all desc").limit(5).size
Text.where(:id => ids)

get the first five Texts/Documents of a company with the most statistic objects this month

ids = Statistic.select("COUNT(*) AS count_all").where('created_at between ? and ?', 1.month.ago, Time.now).where(:loggable_type => "Text").where(:loggable_id => d.texts).group(:loggable_id).order("count_all desc").limit(5).size
Text.where(:id => ids)
