I like Prepopulate. I like to have that pseudo-RESTful way of preloading a form to minimize the amount of work a user has to do to get to the point of submitting a form. But I also like clean URLs. This post reviews in detail a technique to use a single prepopulated nodereference field to prepopulate a bunch of other fields based on that reference. Since Prepopulate’s recent 2.0 release, it because a whole lot more difficult to use the Form API to work magic on what it provides.
I use this in conjunction with nodereference to tailor node forms for their relationship with the referenced node.
