Add find_by_id method

[theblang]

What are your thoughts on a find_by_id method that would mimic ActiveRecord in that it wouldn't throw an exception if the record is not found?

Good with me :)

Nice suggestion. I'd opt to implement something more along the lines of find_by! that would take any attribute and throw an exception if the record isn't found.

@sirupsen I'll have some time over the next week to work on this. How far down the rabbit hole do you think we should go? I'm tempted to add at least these methods:

#find_by("Field" => "Value") => a single matching record, nil on no match
#find_by!("Field" => "Value") => a single matching record, raises on no match
#where("Field" => "Value", "Other Field" => "Etc") => an array of matching records

And I think it wouldn't be a huge lift to get from there to ActiveRecord-style query chains, like Tea.where("Type" => "Black").order("Name" => "asc").limit(10)

What do you think? Would also love to hear from @Meekohi, @theblang and @cbortz.

I'm happy to go the AR-route. I'm wondering if we can lean on some of the AR-tooling, instead of re-inventing it from the ground up? I'm not super familiar with the APIs there, but e.g. being able to support validations and callbacks from those libraries would be neat.
