#db/id[:db.part/db] throws an exception

[edw...@kenworthy.info]

I'm following the Clojure Cookbook recipe for defining a schema in datomic.

One of the forms is: #db/id[:db.part/db] but this generates an exception "clojure.lang.ExceptionInfo: No reader function for tag id :: {:column 25, :line 27, :type :reader-exception}"

Can anyone offer any insight?

Yeah, we shouldn't be telling you to use reader literals like that. Preferred is a call to (d/tempid ...). I'm updating the code now (https://github.com/clojure-cookbook/clojure-cookbook/blob/master/06_databases/6-11_schema.asciidoc)

I've tried that already but then Clojure complains about there being an uneven number of elements in a map.

Curious though: did the original code ever actually work? Is it something that was deprecated?

Have to say I am happy if that's the case, the original seemed unnecessarily arcane where as a standard function call is obvious.

Strangely making the change to my code didn't fix it (I got an exception about an uneven number of elements in a map) but copying and pasting your code -once I'd fixed the half dozen bracket and brace errors that have been introduced- it does work.

Ta.

There are still some errors in there. My bad. Someone came in with a pull request and I'll test it works. 

Generally all the code should have worked originally--I tested every recipe--but I may have missed one or two.
