From 60ad836313b15eb8072bfadcbf657d5275754fde Mon Sep 17 00:00:00 2001 From: Martin Brennan Date: Mon, 13 Feb 2023 22:09:57 +1000 Subject: [PATCH] DEV: Chat service object initial implementation (#19814) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a combined work of Martin Brennan, Loïc Guitaut, and Joffrey Jaffeux. --- This commit implements a base service object when working in chat. The documentation is available at https://discourse.github.io/discourse/chat/backend/Chat/Service.html Generating documentation has been made as part of this commit with a bigger goal in mind of generally making it easier to dive into the chat project. Working with services generally involves 3 parts: - The service object itself, which is a series of steps where few of them are specialized (model, transaction, policy) ```ruby class UpdateAge include Chat::Service::Base model :user, :fetch_user policy :can_see_user contract step :update_age class Contract attribute :age, :integer end def fetch_user(user_id:, **) User.find_by(id: user_id) end def can_see_user(guardian:, **) guardian.can_see_user(user) end def update_age(age:, **) user.update!(age: age) end end ``` - The `with_service` controller helper, handling success and failure of the service within a service and making easy to return proper response to it from the controller ```ruby def update with_service(UpdateAge) do on_success { render_serialized(result.user, BasicUserSerializer, root: "user") } end end ``` - Rspec matchers and steps inspector, improving the dev experience while creating specs for a service ```ruby RSpec.describe(UpdateAge) do subject(:result) do described_class.call(guardian: guardian, user_id: user.id, age: age) end fab!(:user) { Fabricate(:user) } fab!(:current_user) { Fabricate(:admin) } let(:guardian) { Guardian.new(current_user) } let(:age) { 1 } it { expect(user.reload.age).to eq(age) } end ``` Note in case of unexpected failure in your spec, the output will give all the relevant information: ``` 1) UpdateAge when no channel_id is given is expected to fail to find a model named 'user' Failure/Error: it { is_expected.to fail_to_find_a_model(:user) } Expected model 'foo' (key: 'result.model.user') was not found in the result object.

Overview

+
+ +

Module to be included to provide steps DSL to any class. This allows to create easy to understand services as the whole service cycle is visible simply by reading the beginning of its class.

+ +

Steps are executed in the order they’re defined. They will use their name to execute the corresponding method defined in the service class.

+ +

Currently, there are 5 types of steps:

+
  • +

    model(name = :model): used to instantiate a model (either by building it or fetching it from the DB). If a falsy value is returned, then the step will fail. Otherwise the resulting object will be assigned in context[name] (context[:model] by default).

    +
  • +

    policy(name = :default): used to perform a check on the state of the system. Typically used to run guardians. If a falsy value is returned, the step will fail.

    +
  • +

    contract(name = :default): used to validate the input parameters, typically provided by a user calling an endpoint. A special embedded Contract class has to be defined to holds the validations. If the validations fail, the step will fail. Otherwise, the resulting contract will be available in context.

    +
  • +

    step(name): used to run small snippets of arbitrary code. The step doesn’t care about its return value, so to mark the service as failed, #fail! has to be called explicitly.

    +
  • +

    transaction: used to wrap other steps inside a DB transaction.

    +
+ +

The methods defined on the service are automatically provided with the whole context passed as keyword arguments. This allows to define in a very explicit way what dependencies are used by the method. If for whatever reason a key isn’t found in the current context, then Ruby will raise an exception when the method is called.

+ +

Regarding contract classes, they have automatically ActiveModel modules included so all the ActiveModel API is available.

+ + +
+
+
+ +
+

Examples:

+ + +

+

An example from the TrashChannel service

+

+ + 
class TrashChannel
+  include Base
+
+  model :channel, :fetch_channel
+  policy :invalid_access
+  transaction do
+    step :prevents_slug_collision
+    step :soft_delete_channel
+    step :log_channel_deletion
+  end
+  step :enqueue_delete_channel_relations_job
+
+  private
+
+  def fetch_channel(channel_id:, **)
+    ChatChannel.find_by(id: channel_id)
+  end
+
+  def invalid_access(guardian:, channel:, **)
+    guardian.can_preview_chat_channel?(channel) && guardian.can_delete_chat_channel?
+  end
+
+  def prevents_slug_collision(channel:, **)
+    …
+  end
+
+  def soft_delete_channel(guardian:, channel:, **)
+    …
+  end
+
+  def log_channel_deletion(guardian:, channel:, **)
+    …
+  end
+
+  def enqueue_delete_channel_relations_job(channel:, **)
+    …
+  end
+end
+ + +

+

An example from the UpdateChannelStatus service which uses a contract

+

+ + 
class UpdateChannelStatus
+  include Base
+
+  model :channel, :fetch_channel
+  contract
+  policy :check_channel_permission
+  step :change_status
+
+  class Contract
+    attribute :status
+    validates :status, inclusion: { in: ChatChannel.editable_statuses.keys }
+  end
+
+  …
+end

+ + +
+

+ + .contract(name = :default, class_name: self::Contract, use_default_values_from: nil) ⇒ Object + + + + + +

+
+ +

Checks the validity of the input parameters. Implements ActiveModel::Validations and ActiveModel::Attributes.

+ +

It stores the resulting contract in context [“contract.default”] by default (can be customized by providing the name argument).

+ + +
+
+
+ +
+

Examples:

+ + + 
contract
+
+class Contract
+  attribute :name
+  validates :name, presence: true
+end
+ +
+

Parameters:

+
    + +
  • + + name + + + (Symbol) + + + (defaults to: :default) + + + — +
    +

    name for this contract

    +
    + +
    • + +
  • + + class_name + + + (Class) + + + (defaults to: self::Contract) + + + — +
    +

    a class defining the contract

    +
    + +
    • + +
  • + + use_default_values_from + + + (Symbol) + + + (defaults to: nil) + + + — +
    +

    name of the model to get default values from

    +
    + +
    • + +
+ + +
+
+ +
+

+ + .model(name = :model, step_name = :"fetch_#{name}") ⇒ Object + + + + + +

+
+ +

Evaluates arbitrary code to build or fetch a model (typically from the DB). If the step returns a falsy value, then the step will fail.

+ +

It stores the resulting model in context[:model] by default (can be customized by providing the name argument).

+ + +
+
+
+ +
+

Examples:

+ + + 
model :channel, :fetch_channel
+
+private
+
+def fetch_channel(channel_id:, **)
+  ChatChannel.find_by(id: channel_id)
+end
+ +
+

Parameters:

+
    + +
  • + + name + + + (Symbol) + + + (defaults to: :model) + + + — +
    +

    name of the model

    +
    + +
    • + +
  • + + step_name + + + (Symbol) + + + (defaults to: :"fetch_#{name}") + + + — +
    +

    name of the method to call for this step

    +
    + +
    • + +
+ + +
+
+ +
+

+ + .policy(name = :default) ⇒ Object + + + + + +

+
+ +

Performs checks related to the state of the system. If the step doesn’t return a truthy value, then the policy will fail.

+ + +
+
+
+ +
+

Examples:

+ + + 
policy :no_direct_message_channel
+
+private
+
+def no_direct_message_channel(channel:, **)
+  !channel.direct_message_channel?
+end
+ +
+

Parameters:

+
    + +
  • + + name + + + (Symbol) + + + (defaults to: :default) + + + — +
    +

    name for this policy

    +
    + +
    • + +
+ + +
+
+ +
+

+ + .step(name) ⇒ Object + + + + + +

+
+ +

Runs arbitrary code. To mark a step as failed, a call to #fail! needs to be made explicitly.

+ + +
+
+
+ +
+

Examples:

+ + + 
step :update_channel
+
+private
+
+def update_channel(channel:, params_to_edit:, **)

 ## Documentation
 
 The Discourse Chat plugin adds chat functionality to your Discourse so it can natively support both long-form and short-form communication needs of your online community.
 
-For documentation, see [Discourse Chat](https://meta.discourse.org/t/discourse-chat/230881)
+For user documentation, see [Discourse Chat](https://meta.discourse.org/t/discourse-chat/230881).
 
-## Plugin API
-
-### registerChatComposerButton
-
-#### Usage
-
-```javascript
-api.registerChatComposerButton({ id: "foo", ... });
-```
-
-#### Options
-
-Every option accepts a `value` or a `function`, when passing a function `this` will be the `chat-composer` component instance. Example of an option using a function:
-
-```javascript
-api.registerChatComposerButton({
-  id: "foo",
-  displayed() {
-    return this.site.mobileView && this.canAttachUploads;
-  },
-});
-```
-
-##### Required
-
-- `id` unique, used to identify your button, eg: "gifs"
-- `action` callback when the button is pressed, can be an action name or an anonymous function, eg: "onFooClicked" or `() => { console.log("clicked") }`
-
-A button requires at least an icon or a label:
-
-- `icon`, eg: "times"
-- `label`, text displayed on the button, a translatable key, eg: "foo.bar"
-- `translatedLabel`, text displayed on the button, a string, eg: "Add gifs"
-
-##### Optional
-
-- `position`, can be "inline" or "dropdown", defaults to "inline"
-- `title`, title attribute of the button, a translatable key, eg: "foo.bar"
-- `translatedTitle`, title attribute of the button, a string, eg: "Add gifs"
-- `ariaLabel`, aria-label attribute of the button, a translatable key, eg: "foo.bar"
-- `translatedAriaLabel`, aria-label attribute of the button, a string, eg: "Add gifs"
-- `classNames`, additional names to add to the button’s class attribute, eg: ["foo", "bar"]
-- `displayed`, hide/or show the button, expects a boolean
-- `disabled`, sets the disabled attribute on the button, expects a boolean
-- `priority`, an integer defining the order of the buttons, higher comes first, eg: `700`
-- `dependentKeys`, list of property names which should trigger a refresh of the buttons when changed, eg: `["foo.bar", "bar.baz"]`
+For developer documentation, see [Discourse Documentation](https://discourse.github.io/discourse/).

+module Chat
+  module Service
+    # Module to be included to provide steps DSL to any class. This allows to
+    # create easy to understand services as the whole service cycle is visible
+    # simply by reading the beginning of its class.
+    #
+    # Steps are executed in the order they’re defined. They will use their name
+    # to execute the corresponding method defined in the service class.
+    #
+    # Currently, there are 5 types of steps:
+    #
+    # * +model(name = :model)+: used to instantiate a model (either by building
+    #   it or fetching it from the DB). If a falsy value is returned, then the
+    #   step will fail. Otherwise the resulting object will be assigned in
+    #   +context[name]+ (+context[:model]+ by default).
+    # * +policy(name = :default)+: used to perform a check on the state of the
+    #   system. Typically used to run guardians. If a falsy value is returned,
+    #   the step will fail.
+    # * +contract(name = :default)+: used to validate the input parameters,
+    #   typically provided by a user calling an endpoint. A special embedded
+    #   +Contract+ class has to be defined to holds the validations. If the
+    #   validations fail, the step will fail. Otherwise, the resulting contract
+    #   will be available in +context[:contract]+.
+    # * +step(name)+: used to run small snippets of arbitrary code. The step
+    #   doesn’t care about its return value, so to mark the service as failed,
+    #   {#fail!} has to be called explicitly.
+    # * +transaction+: used to wrap other steps inside a DB transaction.
+    #
+    # The methods defined on the service are automatically provided with
+    # the whole context passed as keyword arguments. This allows to define in a
+    # very explicit way what dependencies are used by the method. If for
+    # whatever reason a key isn’t found in the current context, then Ruby will
+    # raise an exception when the method is called.
+    #
+    # Regarding contract classes, they have automatically {ActiveModel} modules
+    # included so all the {ActiveModel} API is available.
+    #
+    # @example An example from the {TrashChannel} service

+# = Chat::Endpoint
+#
+# This class is to be used via its helper +with_service+ in a controller. Its
+# main purpose is to ease how actions can be run upon a service completion.
+# Since a service will likely return the same kind of things over and over,
+# this allows us to not have to repeat the same boilerplate code in every
+# controller.
+#
+# There are several available actions and we can add new ones very easily:
+#
+# * +on_success+: will execute the provided block if the service succeeds
+# * +on_failure+: will execute the provided block if the service fails
+# * +on_failed_policy(name)+: will execute the provided block if the policy
+#   named `name` fails
+# * +on_failed_contract(name)+: will execute the provided block if the contract
+#   named `name` fails
+# * +on_model_not_found(name)+: will execute the provided block if the service
+#   fails and its model is not present
+#
+# @example
+#   # in a controller
+#   def create
+#     with_service MyService do
+#       on_success do
+#         flash[:notice] = "Success!"
+#         redirect_to a_path
+#       end
+#       on_failed_policy(:a_named_policy) { redirect_to root_path }
+#       on_failure { render :new }
+#     end
+#   end
+#
+# The actions will be evaluated in the order they appear. So even if the
+# service will ultimately fail with a failed policy, in this example only the
+# +on_failed_policy+ action will be executed and not the +on_failure+ one.
+# The only exception to this being +on_failure+ as it will always be executed
+# last.
