Find_by_sql sanity check

Rails
1

Hi everyone,

I’m doing a find_by_sql to do a paginated list of a users’ friends’
recipes, but I keep getting an error with my find_by_sql line (Wrong
number of arguments 0 for 1). Is there anything I’m obviously doing
wrong?

    query = "select r.*
      from recipes r, friends_users f
      where r.user_id = f.friend_id and f.user_id = ?
      order by r.date_added desc
      limit #{offset}, #{per_page}"
    @friends_recipes = Recipe.find_by_sql[query, params[:id]]

Let me know if it’s something simple I’ve missed. I can’t figure it
out!

Thanks a lot,

Dave

@friends_recipes = Recipe.find_by_sql[query, params[:id]]

should be…

@friends_recipes = Recipe.find_by_sql(query, params[:id])

I believe…

I tried that as well, and I get an error (Arguments 2 for 1). I can’t
seem to figure out how to give it the right number of arguments, even
though it looks right to me! Frustrating… :slight_smile:
