Create a dependency for a field variable in ModelBuilder?

Question

I'm sure this is quite simple, but I'm missing something. I want to provide the option to select a field in a model. I have added a field variable, but I don't see any way to provide a layer to populate the fields.

In the tool's properties, I can see this as a parameter, but the 'Dependency' option is unresponsive.

How does one plug a layer into a field variable?

Thank you,

Randy McGregor

I have a model that asks for the route id field after the route features have been chosen. Should be a drop-down, but I can't get it to work as a dropdown, so you have to type the name of the field in.

Hi Ed, do you have any update on this functionality? I'm running ArcGIS Pro 3.5 and have found that I'm still not able to set up field dependencies. I've got a ton of experience with Python scripting, but for simple workflows, I prefer to use model builder because I'm building tools for a larger team and would like these simple workflows to be easily maintained by staff that aren't so familiar with scripting. It seems like this is a pretty core feature if Esri would like to offer Model Builder as a viable alternative to scripting in Python. Thanks for looking in to it!

Thank you Ed,

I have quite a bit of experience with Python and have set up dependencies successfully with it. This was my first time trying to set one up with ModelBuilder 🙂
