ruby on rails - Arel returning count column as string instead of int -

-

i have 3 models: video, tag, , tagging. tags have many videos through taggings.

i have added scope tag includes video count each tag attribute on returned records:

class tag   def self.include_video_count     t = tag.arel_table     v = video.arel_table     joins(:videos).select([t[arel.star], v[:id].count.as("video_count")]).group(t[:id])   end end  tag.include_video_count.first.video_count # => "42"

the problem count attribute being returned string instead of integer.

is there arel method missing specifies type value should returned as?

apparently depends on type of column database returns (which makes sense!)

postgres example returns count string.

so... basically.. you're outa luck (as ;)

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
