- Throw your stuff into an instance variable, or pass it in using hash syntax, "new var name (for use in view)" => "what you want to pass to the view"
- using the <%(=) %> tags
- it comes in as a hash, and its called params
- data submitted through a form
Not all the key/value pairs in the params hash will be from a form, but yes data from a from will also be passed through in the params hash
