Why this change?
This change supports a property of `type: category` in the schema that
is declared for a theme setting object. Example:
```
sections:
type: objects
schema:
name: section
properties:
category_property:
type: category
```
The value of a property declared as `type: category` will have to be a
valid id of a row in the `categories` table.
What does this change do?
Adds a property value validation step for `type: category`. Care has
been taken to ensure that we do not spam the database with a ton of
requests if there are alot of category typed properties. This is done by
walking through the entire object and collecting all the values for
properties typed category. After which, a single database query is
executed to validate which values are valid.
Why this change?
This commit updates `ThemeSettingsObjectValidator` to validate a
property's value against the validations listed in the schema.
For string types, `min_length`, `max_length` and `url` are supported.
For integer and float types, `min` and `max` are supported.
Why this change?
This change adds property value validation to `ThemeSettingsObjectValidator`
for the following types: "string", "integer", "float", "boolean", "enum". Note
that this class is not being used anywhere yet and is still in
development.
Why this change?
This is a first pass at adding an objects validator which main's job is
to validate an object against a defined schema which we will support. In
this pass, we are simply validating that properties that has been marked
as required are present in the object.
