I have a Image Media Set that feeds into Pipeline builder. The pipeline pulls meta data from the image along with builds out some other static columns and produces a dataset. This part works great. But I want to be able to add images to the Media Set through Workshop. I figured out that I can do this through the ‘media upload’ widget, but it wants a function-backed action output, which I do not need. It says that I should “For single item uploads that do not need to trigger a function-backed Action, use the Button Group to open an Action form to perform the upload.” But I cannot figure out how to do this through the Button Group widget. Any advice on how to do this?
Hey!
Yep, here is what you have to do:
- Firstly, in Ontology Manager, create an object with a property of type “Media reference” (I suppose you already have that)
- Then, create a new action type which modify the object and select the new media reference property to appear in the form (don’t forget to verify that the type of the parameter is media reference)
- Finally, add a button group widget in your Workshop module, create a new button, and, in the button settings, select the new action to be executed on click
Here are some screenshots of the three steps for you to better understand:
I hope you find this helpful. Feel free to ask if you have any question.
