I was able to get the script to work. I've written down some notes for a quickstart for anyone else who might be following in my footsteps.

1. Create input and output directores where you will drop and emit files. In my example I used:

/Users/Rob/Documents/galaxy-drop/input
/Users/Rob/Documents/galaxy-drop/output

2. Edit the galaxy-dist configuration script (universe_wsgi.ini) and set:

allow_library_path_paste = true

3. In example_watch_folder.py, comment out line 30 and replace it with:

#library_id = library[0]['id] This causes a "key error : 0"

library_id = library['id']

4. CREATE A SAMPLE Workflow & Dataset:

Start Galaxy
Go to USCS and upload the Exons from chr22 to your clean history file
Use the Text Manipulation tool to select the first 5 lines of the gene exon file
Extract the workflow
RESTART Galaxy (You'll get a 500 Internal Server Error if you try to run this without restarting)
Download the exons file to local

5. In your browser go to: http://localhost:8080/api/workflows and identify the id of the workflow you've just created. Let's assume it is (4b187121143038ff) and that your api_key for admin is (8c25bc83f6f9e4001dd21eb7b64f063f)

6. Run the script:

./example_watch_folder.py 8c25bc83f6f9e4001dd21eb7b64f063f http://localhost:8080/api/ /Users/Rob/Documents/galaxy-drop/input /Users/Rob/Documents/galaxy-drop/output "My API Import" 4b187121143038ff

7. Copy the exons file to /Users/Rob/Documents/galaxy-drop/input when the process is complete the file will be placed in /Users/Rob/Documents/galaxy-drop/output

8. In your browser go to: http://localhost:8080/api/histories locate the recently created history and then navigate to:

http://localhost:8080/api/histories/<history_id>/contents

where <history_id> is the id of the history that was created when you ran the dataset on the last workflow.

This is my result. The second file is the output file.

[
    {
        "id": "0d16186aaff7cbfd", 
        "name": "Galaxy1-[Exons_chr22].bed", 
        "type": "file", 
        "url": "/api/histories/2d9035b3fc152403/contents/0d16186aaff7cbfd"
    }, 
    {
        "id": "81991b32733a4fc4", 
        "name": "top200", 
        "type": "file", 
        "url": "/api/histories/2d9035b3fc152403/contents/81991b32733a4fc4"
]

9. You can navigate to the JSON description of the file in your browser:

http://localhost:8080/api/histories/2d9035b3fc152403/contents/81991b32733a4fc4

and the output file can be downloaded here:
http:localhost:8080/datasets/81991b32733a4fc4/display?to_ext=data

Cheers!

Hi Dannon,

Thanks. I've moved to a full size monitor, apparently my eyes are going!

They key error: 0 seems to be the result of a bug in the code.

print(library)

results in:

{'url': '/api/libraries/4b187121143038ff', 'id': '4b187121143038ff', 'name': 'API Import11'}

So library[0]['id'] doesn't point to anything, resulting in the key error. I changed the code on line 30

library_id = library['id']

This seems to fix the issue. I've now got to the section of code where I am watching the in_folder, but there doesn't seem to be any subsequent activity. I'll post my findings or questions as I make progress or lack thereof.

Cheers,
Rob

It should be set on line 29 as the result of that submit function. Can you add (between 29 and 30) a 'print library' to see what that call actually results in?
Off the top of my head, this might be happening if your user account (that the API key is associated with) isn't an admin account -- only admins can create Data Libraries.

Hi Dannon. Thanks! I had been experimenting with BioBlend and forgot to add the /api/ on the url.

./example_watch_folder.py 8c25bc83f6f9e4001dd21eb7b64f063f http://localhost:8080/api/ /Users/Rob/Documents/galaxy-db/input/ /Users/Rob/Documents/galaxy-db/output/ "API Imports" 2a56795cad3c7db3

However, I am now running into a new error when it tries to create the API Imports folder

Traceback (most recent call last):
File "./example_watch_folder.py", line 87, in <module>
main(api_key, api_url, in_folder, out_folder, data_library, workflow )

File "./example_watch_folder.py", line 30, in main
library_id = library[0]['id']
KeyError: 0

(This is coming from the section that creates 'API Imports' library if it doesn't already exist)
24: for library in libs:
25:      if library['name'] == data_library:
26:         library_id = library['id']
27:  if not library_id:
28:        lib_create_data = {'name':data_library}
29:        library = submit(api_key, api_url + 'libraries', lib_create_data, return_formatted=False)
30:        library_id = library[0]['id']
As I mentioned, I'm not familiar with python, but I can't see where 'library[0]['id']' is set or is in scope, since this seems to be the item in the iterator above this section.
Cheers,
Rob

The second argument there should point to the url of Galaxy's API --
in this case http://localhost:8080/api, I'm guessing.
