I have a model that transitions through several states throughout its lifecycle. As the model transitions between states, field attributes change. For example, when in a 'draft' state, some fields of the model are invisible. When in an 'open' state, some fields are readonly.

Right now, all of this view logic is contained within a single view. Consequently, the xml is difficult to read and it is easy to make mistakes in setting field attributes. It seems a better approach would be to have a separate view defined for each model state; however, to do this I would need to know how to select a view based off of a model's state.

How might I implement the conditional selection of views based off of a model's state?

you can use odoo server actions. for eg:

<record model="ir.actions.server" id="print_instance">
    <field name="name">Res Partner Server Action</field>
    <field name="model_id" ref="model_res_partner"/>
    <field name="code">
        if object.some_condition():
            action = {
                "type": "ir.actions.act_window",
                "view_mode": "form",
                "res_model": object._name,
                "res_id": object.id,
            }
    </field>
</record>

so according to the state you just call the action with particular view id. To know more about calling an action with perticular view id refer this link.

Thanks for your response.

There is still a great deal that I don't understand regarding actions in Odoo. The documentation covers their API, but its difficult to understand how and when to use them. For example, the documentation you linked describes a server action as allowing "...triggering complex server code from any valid action location." But I don't know what a "valid action location" is.
