I have a page that lists a set of tasks, each with a status field.
I'd like the ability to update the status from this field, through a
pop-up box. Basically, click the link, a little text area box opens,
the user enters the update, clicks save, the box goes away and the
update appears on the page.
I could probably create this, but figured there may be a helper method
out there already.
Sort of. The in_place_editing helpers were removed from Rails core in
2.0 and made into a plugin. Google 'rails in place edit'. There are
several plug-in options.
Note that this is not specifically what you asked for. That is, this
does not generate a pop-up box. There are lots of reasons not to go
that route including pop-up blockers and the removal of 'target=blank
(etc)' from the standards. If you really want a pop-up, you'll have to
roll your own.
