How do you discover model attributes in Rails

Question

I am finding it difficult to easily see what attributes properties exist on all of my model classes since they are not explicitly defined in my class files   To discover model attributes  I keep the schema rb file open and flip between it and whatever code I m writing as needed   This works but is clunky because I have to switch between reading the schema file to pick up attributes  the model class file to check methods  and whatever new code that I m writing to call attributes  amp  methods     My question is  how do you discover model attributes when you re analyzing a Rails codebase for the first time   Do you keep the schema rb file open all the time  or is there a better way that doesn t involve jumping between schema file  amp  model file constantly
