I am new to both Ruby and ActiveRecord. I currently have a need to modify and existing piece of code to add a date range in the select. The current piece goes like this:
ReportsThirdparty.find(:all, :conditions => {:site_id=>site_id, :campaign_id=>campaign_id, :size_id=>size_id})
Now, I need to add a range, but I am not sure how to do the BETWEEN
or >=
or <=
operators. I guess what I need is something similar to:
ReportsThirdparty.find(:all, :conditions => {:site_id=>site_id, :campaign_id=>campaign_id, :size_id=>size_id, :row_date=>"BETWEEN #{start_date} AND #{end_date}")
Even if this did work, I know that using interpolation here would leave me subject to SQL injection attacks.
I believe you can pass a Range object to ActiveRecord's find and get what you want:
ReportsThirdParty.find(:all,
:conditions => {
:site_id => site_id,
:campaign_id => campaign_id,
:size_id => size_id,
:row_date => start_date..end_date } )
Edit: If you're using Rails 3 you can expect to use something similar to:
ReportsThirdParty.where(
:site_id => site_id,
:campaign_id => campaign_id,
:size_id => size_id,
:row_date => start_date..end_date)
