elabs/pundit: Minimal authorization through OO design and pure Ruby classes - 0 views

authorization rails ruby gem library

shared by 張 旭 on 20 Mar 16 - No Cached
  • The class implements some kind of query method
  • Pundit will call the current_user method to retrieve what to send into this argumen
  • put these classes in app/policies
  • ...49 more annotations...
  • in leveraging regular Ruby classes and object oriented design patterns to build a simple, robust and scaleable authorization system
  • map to the name of a particular controller action
  • In the generated ApplicationPolicy, the model object is called record.
  • record
  • authorize
  • authorize would have done something like this: raise "not authorized" unless PostPolicy.new(current_user, @post).update?
  • pass a second argument to authorize if the name of the permission you want to check doesn't match the action name.
  • you can chain it
  • authorize returns the object passed to it
  • the policy method in both the view and controller.
  • have some kind of view listing records which a particular user has access to
  • ActiveRecord::Relation
  • Instances of this class respond to the method resolve, which should return some kind of result which can be iterated over.
  • scope.where(published: true)

      我想大概的意思就是：如果是 admin 可以看到全部 post，如果不是只能看到 published = true 的 post
  • use this class from your controller via the policy_scope method:
  • PostPolicy::Scope.new(current_user, Post).resolve
  • policy_scope(@user.posts).each
  • This method will raise an exception if authorize has not yet been called.
  • verify_policy_scoped to your controller. This will raise an exception in the vein of verify_authorized. However, it tracks if policy_scope is used instead of authorize
  • need to conditionally bypass verification, you can use skip_authorization
  • skip_policy_scope
  • Having a mechanism that ensures authorization happens allows developers to thoroughly test authorization scenarios as units on the policy objects themselves.
  • Pundit doesn't do anything you couldn't have easily done yourself. It's a very small library, it just provides a few neat helpers.
  • all of the policy and scope classes are just plain Ruby classes
  • rails g pundit:policy post
  • define a filter that redirects unauthenticated users to the login page
  • fail more gracefully
  • raise Pundit::NotAuthorizedError, "must be logged in" unless user
  • having rails handle them as a 403 error and serving a 403 error page.
  • config.action_dispatch.rescue_responses["Pundit::NotAuthorizedError"] = :forbidden
  • with I18n to generate error messages
  • retrieve a policy for a record outside the controller or view
  • define a method in your controller called pundit_user
  • Pundit strongly encourages you to model your application in such a way that the only context you need for authorization is a user object and a domain model that you want to check authorization for.
  • Pundit does not allow you to pass additional arguments to policies
  • authorization is dependent on IP address in addition to the authenticated user
  • create a special class which wraps up both user and IP and passes it to the policy.
  • set up a permitted_attributes method in your policy
  • policy(@post).permitted_attributes
  • permitted_attributes(@post)
  • Pundit provides a convenient helper method
  • permit different attributes based on the current action,
  • If you have defined an action-specific method on your policy for the current action, the permitted_attributes helper will call it instead of calling permitted_attributes on your controller
  • If you don't have an instance for the first argument to authorize, then you can pass the class
  • restart the Rails server
  • Given there is a policy without a corresponding model / ruby class, you can retrieve it by passing a symbol
  • after_action :verify_authorized
  • It is not some kind of failsafe mechanism or authorization mechanism.
  • Pundit will work just fine without using verify_authorized and verify_policy_scoped

Handlebars.js: Minimal Templating on Steroids - 0 views

handlebarsjs.com

javascript mustache jquery template library

shared by 張 旭 on 26 Sep 16 - No Cached
  • Handlebars templates look like regular HTML, with embedded handlebars expressions.
  • don't want Handlebars to escape a value, use the "triple-stash", {{{.
  • Handlebars will not escape a Handlebars.SafeString
  • ...13 more annotations...
  • block helpers are identified by a # preceeding the helper name and require a matching closing mustache, /, of the same name.
  • use Handlebars templates with more raw JSON objects.
  • Nested handlebars paths can also include ../ segments, which evaluate their paths against a parent context.
  • The exact value that ../ will resolve to varies based on the helper that is calling the block.
  • reference the same permalink value even though they are located within different blocks.
  • name conflict resolution between helpers and data fields via a this reference
  • comments will not be in the resulting output.
  • register a helper with the Handlebars.registerHelper method.
  • Helpers receive the current context as the this context of the function.
  • returns HTML that you do not want escaped, make sure to return a new Handlebars.SafeString
  • literal values passed to them either as parameter arguments or hash arguments
  • Handlebars partials allow for code reuse by creating shared templates
  • Handlebars.registerPartial
