@tony.kay: I tried cloning and running the TodoMVC repo but I got the same error as running the server of the tutorial.

user=> (go)

ExceptionInfo please provide a valid file on your file-system  clojure.core/ex-info (core.clj:4593)

I stubbed out the go function in untangled-todomvc/dev/server/user.clj but I still get the same error.

Also I verified via slurping that /usr/local/etc/todomvc.edn has the data.

the atoms for locale are interesting

this means we don't need components to read the :{app,ui}/locale keys, they can just deref the atom

a maybe similar problem: authentication

are the atoms solving just the problem of brevity for tr? i.e. if I'm happy explicitly referring to the auth status in components, can I use read-local without atoms?

oh. https://github.com/omcljs/om/wiki/Thinking-With-Links!

your todo example docs states that server is started at 3000 instead of 3449

forget my last line, just got confused with figwheel and server side stuff

@tomjack: Yeah, use links. The atom is an implementation detail you should not use directly. There is a built-in mutation for setting it via transact!.

If anyone is looking for a contribution to make: automatic server code reload on file change would be nice. I made a stab at it a while ago, but got distracted on other more pressing issues. There are namespace monitoring utils (e.g. see how lein test-refresh works). The trick is not hot-reloading the code that is doing the watching so you don't lose track of things.

I was wondering if server side rendering is in untangled plans for the future (or the present 😄 )

@doddenino: We don't need it here. @anmonteiro did work for that in Om itself, so it should be perfectly compatible.

We're just providing predefined helpers to use Om with, and if we need to add hooks for that kind of thing, be glad to take PR

I see, thanks for the answer!

@tomjack: There is a bug in untangled. @ethangracer is addressing it. We need to actually store :ui/locale in the app state, which got missed...links won't work until we do that, but it is the correct thing to do in order to avoid rendering problems.

It is a trivial patch

Actually, @ethangracer test out a link and see if it does work. The read-local logic might actually work fine for links.

@tony.kay @tomjack just confirmed that links do not work with ui/locale. fix coming shortly

@ethangracer: thanks!

I’m still seeing this error when I try to run the TodoMVC app.

user=> (go)

ExceptionInfo please provide a valid file on your file-system  clojure.core/ex-info (core.clj:4593)

Instructions: Copy resources/config/defaults.edn to /usr/local/etc/

um...forget what you name it

It is in the README

I did that. And verified that the file was there.

server won't start without being configured. That error message is better in the newer untangled-server version

via slurp /usr/local/etc/todomvc.edn has the data

perhaps the README name is wrong. Glance at the code. The name of the config file is a parameter

in the make untangled server

I stubbed out the go function in untangled-todomvc/dev/server/user.clj but I still get the same error.

i’ll double check

that is the correct filename. Make sure it is readable. You might make sure it contains legal EDN

If you are in intellij, you can set an exception breakpoint and examine the problem at the source level

i just tried the same few hours ago, in Cursive, and everything worked as in README

with master branch

Hmm, in todomvc.system namespace did (println (slurp "/usr/local/etc/todomvc.edn”)) and got

{
 :datomic {:dbs {:todo {:url          "datomic:"
                        :schema       "todomvc.migrations"
                        :auto-migrate true
                        :auto-drop    true
                        }}}
 :port    3000}

oh my god

i figured it out

sorry

I was running the repl in the tutorial repo, thinking it was the todomvc repo. Well that was dumb.

It works now.

Thanks, I was just looking at locale as an example. Links worked fine for my authentication problem and I didn't need to change read-local :)

When I add [untangled.datomic.core :refer [build-database]] to my app’s system namespace I get the following exception on boot.

clojure.lang.ExceptionInfo: No reader function for tag db/id
    data: {:file "datomic_toolbox/migration.clj", :line 22}

I suppose it’s happening here. https://github.com/democracyworks/datomic-toolbox/blob/master/src/datomic_toolbox/migration.clj#L22

But the weird thing is I haven’t invoked that build-database function, it just happens automatically on boot.
