Default Model Selection

When Lektor encounters a content file it needs to decide which data model to use for figuring out how to handle the fields. In the ideal case the content file contains _model field which will point explicitly to a model. However if a model was not defined it's picked automatically.

Lektor will attempt to load a few models and will pick the first that exists. If no model exists at all then Lektor calls back to the special none model which is empty other than for system fields.

1. If a model is defined for children by the parent model then it's used. For more information about this feature see Children & Pagination.
2. The ID of the page is attempted as model name next.
3. If it still does not match anything, it will try the default page model.
4. If that also does not match, it falls back to the special none model which is always empty.
