[GIS] How to set .gdb as Python script tool parameter

arcpyfile-geodatabaseparameterspython-script-tool

I was thinking the Geodataset (as shown in figure 1) would be the right choice if I want to use .gdb as a parameter when using script tool, but it didn't work since I couldn't add my gdb to the box, shown in figure 2. What is the right parameter type I should use here?

Using 10.3.1 ArcGIS Advance License.

The parameter you need is: workspace

At the moment your ToolValidator code is trying to apply a filter list to your first parameter (featureClasses).

You need to add a third parameter of type string (e.g. Region Value), then in your ToolValidator change this

self.params[0].filter.list = sorted(list(set(r.getValue('REGION') for r in rows)))

self.params[2].filter.list = sorted(list(set(r.getValue('REGION') for r in rows)))

You may also want to pull the bit of code that creates the unique list of REGION values out of the def updateParameters(self): block otherwise it will fire every time any of the parameters is altered which could cause performance issues.
