    1. COThats Kinda similar to what I was thinking. It seems that using something like `property :role, Enum[ :client, :worker, :manager ]` would basically give me what you described in one line. My understanding is that something can only be _one_ Enum at a time. _(ie. `user.role = :worker` would overwrite whatever the current value of :role)_ Whereas a `Flag` can hold any of the defined values as a property. I get `Enum`, but I don't understand the relationships of `Flag` _(ie. How would one set & unset particular values of `Flag`? *(can they be unset once set?)* )_

    2. COThanks that actualy helped alot. For some reason it just wasn't clicking from reading the Docs and other people's examples. I'm just haveing one last problem. Let's say that each model also has a name value, tree_name, apple_name, seed_name. I would like to be able to find by that name. ie. `Tree.get('Wanda')` but if I add `:key, => true` to tree_name `Tree.get('Wanda')` tells me attribute error 1 for 2. `Tree.get(1, 'Wanda')` returns `< @Id = 1, @tree_name = "Wanda">`. I read te Docs and thought that adding the `:key, => true` could be added to any property to make it a key value.

    3. COIdeally, I would like to be able have something like `.client?` and have that return `true` or `false`. So that I can do something like `if @ura.client?`. _(I'm fine with figuring out the code for that on my own, I'm just trying to get a handle on the best way to represent that information.)_

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
