Manages user follows for bloggers.
This resource represents follow relationships where users can follow bloggers to stay updated with their content. Each follow links a user to a specific blogger and tracks when the follow occurred and notification preferences.
The unique constraint on follower_user_id and blogger_id ensures each user can only follow a specific blogger once. The notification_enabled field allows users to control whether they receive notifications about the blogger's new content.
This resource has no multitenancy of its own, so a follow may only name a blogger of the site
it is made for — see MishkaCmsCore.Runtime.Resources.Validations.TenantIsolation — and
:by_blogger lists only the followers of a blogger of the site it is asked on, and gives a site
user nothing on any site but its own — see MishkaBlog.Resources.Preparations.SiteAskedOn.
Database-level constraints ensure data integrity with cascade deletes when bloggers or users are
removed.
Summary
Functions
Apply the full GuardedStruct pipeline (sanitize → validate → derive →
main_validator) to attrs and return either {:ok, transformed_attrs}
or {:error, errors}. Wire this into an Ash.Resource.Change to plug
guardedstruct rules into Ash's changeset pipeline.
O(1) lookup of a field's compile-time metadata by name. Returns
nil for unknown fields.
Compile-time-baked MapSet of every field name owned by the
guardedstruct block. Used by GuardedStruct.AshResource.Change
to decide, in O(1), whether a key in changeset.atomics
belongs to the pipeline.
Validates that the keys in the provided input are valid for at least one action on the resource.
Same as input/1, except restricts the keys to values accepted by the action provided.

Functions
Apply the full GuardedStruct pipeline (sanitize → validate → derive →
main_validator) to attrs and return either {:ok, transformed_attrs}
or {:error, errors}. Wire this into an Ash.Resource.Change to plug
guardedstruct rules into Ash's changeset pipeline.
The function is named __guarded_change__ because it does more than
validate — it can also transform values (trim, downcase, slugify,
auto-fill, etc.) before they reach the data layer.

nil for unknown fields.

Validates that the keys in the provided input are valid for at least one action on the resource.
Raises a KeyError error at compile time if not. This exists because generally a struct should only ever
be created by Ash as a result of a successful action. You should not be creating records manually in code,
e.g %MyResource{value: 1, value: 2}. Generally that is fine, but often with embedded resources it is nice
to be able to validate the keys that are being provided, e.g
Resource
|> Ash.Changeset.for_create(:create, %{embedded: EmbeddedResource.input(foo: 1, bar: 2)})
|> Ash.create()Same as input/1, except restricts the keys to values accepted by the action provided.
