Newbie problem with template path
I am having a problem to understand the path where the engine looks for
the files included with the !json and !code macros.
More exactly: I am having a
{
"_id": "_design/example",
"_rev": "11-4ca79b908a6278eeb8d4d5e2e6488fb5",
"views": {
"foo": {
"map": "function(doc){ emit(doc._id, doc._rev+'QQQ')}"
}
},
"shows": {
"my": "function(req, doc) {
// !json templates.edit
return template(templates.edit,{}) ; }"
}
}
and
http://localhost:5984/mydatabase/_design/example/_view/foo
as expected. However
http://localhost:5984/mydatabase/_design/example/_show/my
produces a
{"error":"normal","reason":"{gen_server,call,\n
[couch_query_servers,\n
{ret_proc,{proc,<0.21518.0>,<<\"javascript\">>,\n
{couch_os_process,prompt},\n
{couch_os_process,set_timeout},\n
{couch_os_process,stop}}}]}"}
I am having a non-empty
{
"_id": "_design/template/_show/my",
"_rev": "2-7051cbe5c8faecd085a3fa619e6e6337"
}
but this does not seem to help here. Moreover, where do I place the
template content into this object ?
I never got that part working so probably it is just a very stupid
newbie error...

The first (CommonJS require) made it into 0.11 and I've just commented on the second with the correct way to load templates (the _design doc is available as the "this" object in _show _list etc functions).
Thanks for bringing these to my attention. I've closed them both.

OK, after a little more digging, I found some JIRA issues that seem to
be related:
https://issues.apache.org/jira/browse/COUCHDB-658
"Add CommonJS style modules to the view server" — I imagine this would
be useful for loading a templating library.
https://issues.apache.org/jira/browse/COUCHDB-693
"require function - add support for requiring plain html/xml files in
addition to only javascript" — this seems it would be the mechanism
for loading the templates themselves.
They are both marked as open and unassigned, so I assume neither made
it in to 0.11. Since 0.11 is supposed to be a feature freeze for 1.0,
I suppose that means that these features will be post-1.0?

Back in February, Clemens pasted this from an email from Chris:

Now that 0.11 has been released, I'm wondering if this happened? I
can't seem to find any documentation on such a feature.
Thanks!

No, I am not.
I got a reply from Chris which pointed out that issue - and as a
consequence of this my issue got solved today at (local time) noon. :-)
Since his reply didn't make it to the list I provide the essentials here
for the benefit of others - since this was the missing link for me.
Thanx again !

Ahh. the key is that you need to use `couchapp push` to upload your
design doc to the couch.
when it's pushed, the couch should have:
shows : {
my : {
"
function(doc) {
var templates = {
edit : "TEXT"
}
return templates.edit;
}
"
...
CouchDB itself has no idea about //!json, it's all in the toolchain.
(We're working on changing this but the syntax will be proper javascript
instead of a macro. This will be in 0.11 and will make it easier for you.)
Couchapp push is required. Without it of course you could just put the
template into your function by hand, but that's no fun.

To confirm...
You *are* using couchapp to generate your design doc, keeping the view and
show funcs in files, and the included files in the same couchapp area?

I replied to this on the CouchApp list, but it somehow didn't go
through. Lemme see if I can dig it out of buffer or something and
repost it. But not till after I walk the dogs.
The gist is to have it all in one design doc, so it replicates
properly. See the source layout of http://github.com/jchris/taskr/ for
examples.
