Database schema for calendar application -

-

i'm creating calendar application in each date has 1 of 3 states: available, maybe available, , unavailable. trying figure out best schema situation.

one thought might have userdate model field state. problem db have #-of-users- x 365 rows each year - seems grow modestly sized app.

another thought might have default state, , create userdate object when user has signified availability on date different default. seems convoluted though.

has dealt situation before? suggestions on best way go this?

when create new user, not want inserting records next 50 years of life. creating userdate object when there non-default value should do.

you consider storing range of dates user if have lots of consecutive dates same status. example, if unavailable of december, represented single row.

think sort of information want extract database, , how difficult each of possible designs.

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.
