ruby on rails 3 - Having a problem with my Model query -

pls have next code in model

letter.count(:id, :conditions => ["language_id = #{lang} , :created_at => '#{start_date.to_date.strftime('%y-%m-%d')}'..'#{end_date.to_date.strftime('%y-%m-%d')}' " ])

i trying count of letters.id of different letters between given dates. error having...

please know doing wrong...thanks

sqlite3::sqlexception: near ">": syntax error: select count("letters"."id") "letters" ("letters".language_id = 1) , (language_id = 1 , :created_at => '2011-05-01'..'2011-05-08

this can much simplified. couple points:

you don't utilize :created_at => ... format within string you need utilize between ? , ? dates. you don't need manually strftime dates, rails handle automatically. in rails 3, preferred way utilize where(...) instead of :conditions hash count(...). you should utilize rails' safe interpolation language_id field too

letter.where("language_id = ? , created_at between ? , ?", lang, start_date.to_date, end_date.to_date).count
