Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Control pattern. This pattern splits the view (also called the presentation) into "dumb" templates that are primarily responsible for inserting pre-built data in between HTML tags. The model contains the "smart" domain objects (such as Account, Product, Person, Post) that holds all the business logic and knows how to persist themselves to a database. The controller handles the incoming requests (such as Save New Account, Update Product, Show Post) by manipulating the model and directing data to the view. In Rails, the model is handled by what’s called an object-relational mapping layer entitled Active Record. This layer allows you to present the data from database rows as objects and embellish these data objects with business logic methods. You can read more about Active Record in link:files/vendor/rails/activerecord/README.html. The controller and view are handled by the Action Pack, which handles both layers by its two parts: Action View and Action Controller. These two layers are bundled in a single package due to their heavy interdependence. This is unlike the relationship between the Active Record and Action Pack that is much more separate. Each of these packages can be used independently outside of Rails. You can read more about Action Pack in link:files/vendor/rails/actionpack/README.html.

Hers is a DF for test:
...ANSWER
Answered 2021-Apr-04 at 15:17As I understand it, you want to look at the row before, and see if there are any changes, and continue throughout the dataframe. I believe this can be done by looking at a lag and then filtering down to rows where the lagged value and current value differ. Assuming your dataframe is sorted as in your test, this should work:
