I'm using a managed folder to hold a list of unstructured files a dev plugin needs to read in as input

path <- dkuManagedFolderPath("PATHWAYANALYSIS.Genesets")

When I use this dev plugin within the "PATHWAYANALYSIS" project, all is good. When I try and use it within another project I get messages like - 

[2018/07/13-00:25:44.420] [null-out-37] [INFO] [dku.utils]  - > path <- dkuManagedFolderPath("PATHWAYANALYSIS.Genesets")
[2018/07/13-00:25:44.442] [null-err-38] [INFO] [dku.utils]  - Error in dku__check_api_error(resp, "Failed to get Box path") : 
[2018/07/13-00:25:44.443] [null-err-38] [INFO] [dku.utils]  -   Failed to get Box path (HTTP code 500): Managed folder name not found: Genesets in PATHWAYANALYSIS

Can anyone think of a creative way to allow a plugin to read files from one project and run in another project?


Many thanks

Solved my own problem. 

The way to do it is to add another input to your plugin that accepts managed folders ("acceptsManagedFolder": true) https://doc.dataiku.com/dss/latest/plugins/reference/recipes.html

Then read this input in your plugin and use it to get the path for the managed folders

"inputRoles" : [
            "name": "genesets_input",
            "label": "Managed folder of genesets",
            "description": "The list of genesets to use in this analysis",
            "arity": "UNARY",
            "required": true,
            "acceptsDataset": false,
            "acceptsManagedFolder": true

and then in your R recipe code

genesets_input = dkuCustomRecipeInputNamesForRole("genesets_input")
path <- dkuManagedFolderPath(genesets_input[1])

Then share the managed folder with the project that needs it to run the plugin. As a bonus you see the managed folder being included in your flow graph.
