Discovers and caches the Ecto schema module for a given mediable_type string.
This is the inverse of HasMedia.__media_type__/0 — given a string like
"posts", it finds the module (e.g. MyApp.Post) that declared
use PhxMediaLibrary.HasMedia and whose __media_type__/0 returns that
string.
Lookup Strategy
- Check the explicit registry in application config (
:model_registry) - Scan all loaded modules that export
__media_type__/0
Results are cached in :persistent_term for fast repeated lookups.
Explicit Registry
For production deployments where module scanning is undesirable, you can configure an explicit mapping:
config :phx_media_library,
model_registry: %{
"posts" => MyApp.Post,
"users" => MyApp.User
}Summary
Functions
Finds the Ecto schema module that corresponds to the given mediable_type.
Returns the conversions defined on module for the given collection_name.
Functions
Finds the Ecto schema module that corresponds to the given mediable_type.
Returns {:ok, module} on success, or :error if no module could be found.
Examples
iex> PhxMediaLibrary.ModelRegistry.find_model_module("posts")
{:ok, MyApp.Post}
iex> PhxMediaLibrary.ModelRegistry.find_model_module("unknown")
:error@spec get_model_conversions(module(), atom()) :: [PhxMediaLibrary.Conversion.t()]
Returns the conversions defined on module for the given collection_name.
Tries get_media_conversions/1 first (which filters by collection), then
falls back to media_conversions/0 (unfiltered list). Returns [] if the
module doesn't define either function.
Examples
iex> PhxMediaLibrary.ModelRegistry.get_model_conversions(MyApp.Post, :images)
[%PhxMediaLibrary.Conversion{name: :thumb, ...}, ...]
