Question

I have the following code:

def analytics 
    @user_registrations = User.count(:conditions => ["created_at >= ?", 30.days.ago.to_date], group: "date(created_at)")
    @daily_count = []
    30.times do |day|
      @daily_count << [Date.today - day, @user_registrations['#{Date.today - day}']]
    end
  end

which when run with: <%= simple_format @user_registrations.to_yaml %> produces:

--- !omap 
- '2012-08-23': 11

I want to get the 11 value out and put that in my daily_count array.

How can I do that?

update:

<%= simple_format @user_registrations.to_yaml %>
<%= simple_format @daily_count.to_yaml %>

results in the image:

Just replace:

@daily_count << [Date.today - day, @user_registrations['#{Date.today - day}']]

with:

@daily_count << [Date.today - day, @user_registrations["#{Date.today - day}"] || 0]

Single quotes will cause the #{} escape syntax to be treated as a literal, double quotes cause it to be eval’ed.
