![]() ![]() It is worth going through the list of files that is ignored and resolve them (and auto upgrade the types of other files see initial setup above). This is because sometimes Rails allows very dynamic code that Sorbet does not believe it can typecheck. ![]() #214 Tips & Tricks Look for # typed: ignore filesīecause Sorbet's initial setup tries to flag files at whichever typecheck level generates 0 errors, there may be files in your repository that are # typed: ignore. In addition to requireing sorbet-rails, you must also runīundle exec rake rails_rbi:custom, which will produce the RBI for these runtime features. Add type alias, eg Model::RelationType, to represents any type of relation of a model.Ĭontroller: use TypedParams to convert controller parameters to a typed structure.By default, relation classes like User::ActiveRecord_Relation, User::ActiveRecord_AssociationRelation are private Model: The gem provides some helper method to a model to make type-checking easier: Instructions specify that sorbet-rails should be placed in the :default Provide additional features when required. In addition to features provided by the static generator, sorbet-rails can If there is a (sorbet) sig written for perform, it will use the same sig for perform_* methods. The job classes matching the signature of the perform method of the job. It will generate perform_later and perform_now methods for This Rake task generates an RBI file defining _path and _url methods for all named routes in routes.rb: Note: require_typed and fetch_typed are deprecated in favor of TypedParams. If this feature is supported by sorbet in the future, it will be easy to codemod to be TypedParams.extract(.)! part from your code. However, sorbet doesn't support defining a method that accept a type and return an instance of the type. Ideally, the API can be simply TypedParams.extract!(.). Note: The API ! may seem verbose, but necessary to support this feature. If it fails to coerce the params into the right type, an ActionController::BadRequest exception will be raised with the coercion context for debugging. The attributes plucked is based on props defined in the T::StructĬlass M圜oolController MyActionParams # T.reveal_type(typed_params.show) => T.nilable(T::Boolean) end end Sorbet-rails provides pluck_to_tstruct method as a replacement that returns an array of T::Struct instead. However, it doesn't have any type information: it doesn't have type information (or name) of the attribute plucked. The pluck method in Rails is a performant way to query value without instantiating ActiveRecord objects. We also add following methods to make type-checking easier: Check out the plugins section below if you are interested. It is possible to add custom RBI generation logic for your custom module or gems via the plugin system. Scopes on Relation, but not class methods.The generation task currently creates the following signatures: ![]()
