RE: [Myexperiment-discuss] adding stuff

[Linde, A.E.]

Many thanks, Dave. That's great. I'll have a crack at that next.

<< didn't specify that Graphviz needed to be
installed in my set of instructions>>

Ah, is that why images are missing - didn't think to check the error messages.

Cheers,
Tony.

Hi Tony,

I would suggest doing the 3 stages you are talking about as follows:

1.  You will want to put you sacEndpoint variable in the
environment_private.rb file.  This is in the config directory of the trunk.
As this variable will remain constant whilst myExperiment is running, we
have tended to use the standard naming convention for constants of making
the name all upper case (e.g. SAC_ENDPOINT).

2. You could create you own SKUA javascript file but I sense there is not
too much code so you might as well add it to application.js in the
public/javascripts directory.  A function to load the app I would guess
wold look a bit like the one below.

function loadSkuaApp() {
  var url = "<%= SAC_ENDPOINT %>" //Plus any additional information it can
be passed on loading.
  window.open(url);
}

3. As you said in your email, I think it would be quicker for you figure
out number 3 than for me to explain it.  It would just be a couple of lines
of code in app/views/workflows/show.rhtml.

Also in response to your previous email that I think Don is responding to.
I have just realised that I didn't specify that Graphviz needed to be
installed in my set of instructions.  I have now added it to the latest
version of developers.txt.
