accessing hda "extra files" using python.

[TomRaynor]

Hi everyone,

I have an hda which has a python module inside it that needs to access a '.json' (jscript) file.

Basically there is a line of code in my python module that says something along the lines of:

BLAH = 'C:\Users\Me\Desktop\blah.json'

This string variable then gets passed to a function that does other shit...

As is, this works fine, and executes correctly, however I want to have the '.json' file embedded in the extra files section of my otl instead of being loose on my desktop.

My question is can anyone help me with the pythonic syntax to access the path to the file within the extra files section of the otl?

I currently can't get it to work pick up the file.

I have tried things like:

BLAH = hou.readFile('opdef:./?client_secrets.json')

and

BLAH = hou.hscript('opdef:./?client_secrets.json')

Either I have got these wrong syntactically or they don't work as I have expected.

Any help would be much appreciated!

Cheers

I'd access the it using the hou.HDADefintion's sections() method.

definition = asset.type().definition()
secrets = definition.sections()['client_secrets.json'].contents()

The hou.readFile method does work, however it doesn't understand the relative '.' part for the opdef: call. You need to do the full operator name:

hou.readFile("opdef:/Sop/something?client_secrets.json")
hou.readFile("opdef:/{0}?client_secrets.json".format(asset.type().nameWithCategory()))

Hey Graham,

Thanks for the reply, that is really great stuff. However I believe that the python method that I am using requires the path to the '.json' file rather than the actual contents of it to work...

I believe this is why it worked when I used the explicit path:

BLAH = 'C:\Users\Me\Desktop\blah.json'

Is it possible to get some sort of path to the extra file within the otl so that I can feed it into this method?

Thanks again!

I don't believe so. What module/method are you using with the file path?

[TomRaynor]

I am working on a project where I access website data using the google AP. It is a method called:

flow_from_clientsecrets()

For which the docs can be found here:

https://developers.g...m_clientsecrets

Any thoughts?

Whilst you ponder on that one, I have a couple of another questions I was meaning to ask...

It seems you can only have one "pythonModule" in the scripts section of your otl. Is this true or can we access and run multiple python modules from this location?

If I have some extra python files in either the scripts section of my otl or the extra files section of my otl, is it possible for me to import those modules into the "pythonModule" within my scripts directory so that I can have access to the code contained within them?

Cheers!

Not really. I suspect you'll have to come up with some sort of intermediate copy of the file that gets written out on load or something so that the API call can handle it.

You can store and access additional Python module sections like this

Great, thanks for all the info Graham. Much appreciated!
