What is OnModelCreating?
The DbContext class has a method called OnModelCreating that takes an instance of ModelBuilder as a parameter. This method is called by the framework when your context is first created to build the model and its mappings in memory.
How do I run a .PY file in ArcGIS?

How do I use the iterate feature classes iterator in ModelBuilder?
After adding the Iterate Feature Classes iterator to ModelBuilder, follow these general steps: Specify an input workspace, such as a geodatabase, to iterate through every feature class in that workspace. Specify a wildcard and feature type (in the example, only polygon feature classes with a name starting with the letter I will be included).
What is the use of for iterator in Python?
