New React Element Factories and JSX

In React 0.12, we're making a core change to how React.createClass(...) and JSX works.

If you're using JSX in the typical way for all (and only) React components, then this transition will be seamless. Otherwise there are some minor breaking changes described below.

The Problem

If you import live data into Google Docs spreadsheets using the importdata function and you want to force a refresh at a certain interval, but you also want to ensure that some cache-busting goes on, append a querystring that's the epoch time value that the refresh occurs, so for a sheet that should grab new data every hour you could force an update like this:

importData("http://example.com/data.csv?" & hour(googleclock()) & ")")

But the url requested looks like this: http://example.com/data.csv?11 if the refresh happened at 11am. The next day at 11, the url will be the same, so there's a chance you may get cached data. To get around this, use an epoch time-based refresh. The formula:

=((date(year(googleclock()),month(googleclock()),day(googleclock())) & " " & time(hour(googleclock()), 0, 0)) - DATE( 1970;1;1))*86400

gives you the epoch timestamp for the time at the current hour. If you wanted the timest

First-use of the message template

<% renders messages/_message.html.erb %>
<%= render @messages %>

Form submitting via Ajax

<%= form_for @project.messages.new, remote: true do |form| %>
 ...

Description
