I have a question about hanami v2.

I use hanami/interactor now with hanami v1, but I found hanami/interactor was removed from hanami v2.
https://github.com/hanami/utils/blob/main/CHANGELOG.md#v200beta1---2022-07-20

Does Anyone know why hanami/interactor was removed?
And how we should change the old interactor? (For example we think we'll change expose to attr_reader and error! method to raise. Is it the right way in hanami v2? ref: https://docs.hanamirb.org/1.3.3/hanami/interactor)

It looks like templating is just up to the end user to figure out? I don't see any docs in 2.0 regarding the view layer, just response.body = <your problem> ?

Not that templating engines are hard to setup, just wondering if I missed something pre-decided or built in

Seb Wilgosz

@swilgosz

Templating is not done for 2.0, will be added with 0ersistance in 2.1. for now yes, You need to figure it out, but I will prepare a tutorial very soon on Hanami Mastery

Hi guys, I was trying Hanami 2.0 and faced an issue with the dev server port configuration. This is a new project, with no modifications after running hanami new bookshelf.

$ bundle exec hanami version
v2.0.0

$ HANAMI_PORT=5000 bundle exec hanami server

For some reason hanami server doesn't react to changes in env variables or changes to the .env file. While with puma it's working as expected.

I am trying to add Rack::Static middleware to my Hanami 2.0 app but am encountering error while starting server.

# config/app.rb

# frozen_string_literal: true

require "hanami"

module StartupTemplate
  class App < Hanami::App
    config.middleware.use Rack::Static, urls: ["/css", "/images"], root: "public"

Checking the source code https://github.com/hanami/hanami/blob/beb60078bc9a5e84ba77946f2823ee12f7f6d0dc/lib/hanami/slice/routing/middleware/stack.rb#L94 the *args is expected to be an optional Array. And the specs at https://github.com/hanami/hanami/blob/beb60078bc9a5e84ba77946f2823ee12f7f6d0dc/spec/integration/rack_app/middleware_spec.rb doesn't illustrate any middleware accepting keyword args as middleware's option. So is it that Hanami doesn't support middlewares accepting keyword args?

Hi! Congratulations to everyone on the 2.0 release, I've been waiting for it for a very long time!

I decided to test Hanami 2.0 and did everything according to the documentation from A to Z. I reached the configuration of middleware body_parser.
I just wanted to add my own JSON body parser, like Oj. I looked and did as described in the documentation, but got an error in the RSpec tests.

NoMethodError:
       undefined method `empty?' for #<OjParser:0x0000000101363df8>

                 return DEFAULT_BODY_PARSERS if parser_specs.empty?
                                                            ^^^^^^^

I saw that the empty? method is missing somewhere and added it to my custom parser. But I don't understand where it is being called from.

The working version of the code looks like this:
But I'm not sure if this fix is in the right place.

# config/app.rb

config.middleware.use :body_parser, OjParser.new

# lib/oj_parser.rb

class OjParser
  def mime_types
    ['application/json']
  end

  def parse(body)
    Oj.load(body) unless body.empty?
  end

  # dummy method
  def empty?
    false
  end
end

I created pull request for guide, but we need to find a place in the code where to fix it:

Hey there, in an Hanami::Action::Params is it possible to use rules?

oh nevermind, rules is embedded in params block

Michael Baldry

@mikebaldry

Next question - I'm injecting a dependency in to my Params with include Deps['utils.email_validator'], but I notice in my spec, I just pass that dependency in on the initializer along with the param keys. What's to stop them conflicting and user input overriding a dependency?

Michael Baldry

@mikebaldry

and back to the previous question, the rules block doesn't seem to get called at all

Michael Baldry

great work by the way!

Hello,

In my Hanami 2.0 application have some questions regarding settings and app config. Please refer the code below.

# config/settings.rb

# frozen_string_literal: true

module StartupTemplate
  class Settings < Hanami::Settings
    # Define your app settings here, for example:
    #
    # setting :my_flag, default: false, constructor: Types::Params::Bool

    setting :database_url, constructor: Types::String

    def production_log_level
      determine_production_log_level
    end

    private

    def determine_production_log_level
      @use_as_production_log_level ||= LogUtil::LOGGER_METHODS[0]
    end
  end
end

# lib/startup_template/log_util.rb

# auto_register: false
# frozen_string_literal: true

module StartupTemplate
  module LogUtil
    extend self

    LOGGER_METHODS = [
      :debug,
      :info,
      :warn,
      :error,
      :fatal
    ].freeze
  end
end

# config/app.rb

# frozen_string_literal: true

require "hanami"

module StartupTemplate
  class App < Hanami::App
    config.actions.content_security_policy[:default_src] = "'self'"

    # ======== STARTS: LOGGER CONFIG

    config.logger.formatter = :json
    config.logger.stream = root.join("log").join("#{Hanami.env}.log")

    environment(:production) do
      config.logger.level = settings.production_log_level
    end

    # ======== ENDS: LOGGER CONFIG
  end
end

When starting the console for development env it loads without any errors. However when starting the console for production env it doesn't load and shows error uninitialized constant

startup_template$ HANAMI_ENV=production bundle exec hanami c

  from /home/jignesh/.rvm/gems/ruby-3.1.2@startup-template-hanami-2-0/g

Doing some trial and error I found the culprit to be following in StartupTemplate::App

  environment(:production) do
    config.logger.level = settings.production_log_level
  end

If I replace settings.production_log_level with a hardcoded value say :info then the production console loads successfully.

Which makes me ask: Is it that the "determined settings" (as in custom method in StartupTemplate::Settings involving some logic using other classes in lib/startup_template folder) cannot be used for assigning to a configuration value in StartupTemplate::App? If yes, then one question which puzzles me is why that same thing doesn't cause error when loading development env console?

Hi there. I've just read https://hanamirb.org/blog/2022/11/22/announcing-hanami-200/ , and I have a question: how does the concept of "slices" differs from "domain" (as in DDD)?

@danblack1800_twitter there is ongoing discussion on forum related to this https://discourse.hanamirb.org/t/discussion-of-app-structure-for-2-1/759/6

Hey folks, thank you for the great framework! Got a question about a proper way of including development-only libraries for specific environments.

I want to use pry-byebug library in development and test environments and have it available globally so I don't have to require it each time I wanna use binding.pry e.g.:

# someplace in the app ...
# this
binding.pry

# not this
require 'pry-byebug'; binding.pry

Here's what I have now.

Gemfile

group :development, :test do
  gem "pry-byebug"
end

config/app.rb

require "hanami"
require "pry-byebug" if Hanami.env?(:development, :test)

module Bookshelf
  class App < Hanami::App
    # ...
  end
end

This works, but I was just wondering whether there is a more Hanami-idiomatic way of doing this? Having to specify in both the Gemfile AND in the config/app.rb that I want it only for those environments seems non-ideal.

Thank you.

Hi there!

I'm trying to get the endpoint of a RecognizedRoute as stated in: https://github.com/hanami/router#testing

But what I'm getting instead of a String is a Proc that when called with env executes the actual request.

Am I doing something wrong?
Is there any other way of getting the human readable action/route from a Request?

Thank you!

Hey, I've added some scoped routes with nested params like so:

    scope "secrets" do
      get "/", to: "secrets.index"
      post "/", to: "secrets.create"
      patch ":id", to: "secrets.update"
      delete ":id", to: "secrets.destroy"

      scope ":secret_id/parts" do
        post "/", to: "parts.create"
        delete "/:id", to: "parts.destroy"
      end
    end

but I'm getting 404 when I call the DELETE /secrets/:secret_id/parts/:id path. The hanami routes output displays it correctly as DELETE /secrets/:secret_id/parts/:id parts.destroy. I've disabled all additional headers but it still cannot be resolved, however if I specify the route outside the scope as delete "/secrets/:secret_id/parts/:id", to: "parts.destroy" it is resolved successfully, how do I organize routes within scopes if I have multiple nested objects to query? Thanks!

The lib/bookshelf/persistence/relations/books.rbdoes exist, though. Any idea? Thanks!

Hi community!

I have some great news for all of us that are using Hanami and Appsignal!

This autumn, my team started building a production application in Hanami 2. We wanted to use Appsignal for monitoring so we reached out to the Appsignal team to ask them to add support for Hanami. Yesterday I got these news from their team:

"Hi Hannes 👋 We released ruby gem version 3.3.0, which supports Hanami 2."

Changelog with mention about Hanami 2 support: https://github.com/appsignal/appsignal-ruby/blob/main/CHANGELOG.md#330

A getting started guide: https://docs.appsignal.com/ruby/integrations/hanami.html

Hello,

I am unable to use Custom Types defined in lib/types.rb. For e.g. in my Hanami 2.0 application I modified that file in following manner:

require "dry/types"

module StartupTemplate
  Types = Dry.Types

  module Types
    # Define your custom types here

    # Reference: https://dry-rb.org/gems/dry-validation/1.8/schemas/#using-custom-types
    StrippedString = Types::String.constructor(&:strip)
  end
end

and then tried to access it from hanami console and encountered error:

startup_template$ hanami c
startup_template[development]> StartupTemplate::Types::StrippedString
NameError: uninitialized constant StartupTemplate::Types
from (pry):1:in `__pry__'

Then I tried to use that custom type in a dry-validation contract like following:

module StartupTemplate
  module ServiceObject
    module CreateDoctor
      class Validate < Dry::Validation::Contract

        params do
          # TODO: Using a Custom type defined in lib/types is not working.
          #required(:name).value(::StartupTemplate::Types::StrippedString)
          #required(:qualification).value(::StartupTemplate::Types::StrippedString)

          required(:name).filled(:string)
          required(:qualification).filled(:string)
        end

      end
    end
  end
end

and accessing a page which should invoke that validation I encountered following error:

Puma caught this error: uninitialized constant StartupTemplate::Types

          required(:name).value(::StartupTemplate::Types::StrippedString)
                                                 ^^^^^^^ (NameError)

Can anybody help me in figuring out where is the problem?

On another note at https://dry-rb.org/gems/dry-types/1.2/getting-started/ following can be seen

module Types
 include Dry.Types()
end

however in Hanami 2.0 default generated lib/types.rb file looks like following:

require "dry/types"

module StartupTemplate
  Types = Dry.Types

  module Types
    # Define your custom types here
  end
end

Why this difference?

Also the type registration illustrated at https://dry-rb.org/gems/dry-schema/1.10/advanced/custom-types/ how can I leverage it in my Hanami 2.0 application?

Hey, I have a pending problem in my template with the prompt for select: select :client_id, clients_for_select, options: {prompt: (I18n.t :gm_contact_new_prompt_select_client)}. The problem is that the prompt is not displayed as the "prompt". Rather the first value in client list is shown as selected:

clients_for_selectis just an ordinary hash. Any idea why it doesn't display the prompt?

Hello. :wave: What is the right way to render a partial from an action? Here's how I'm currently doing it:

...but what I'd really like to do is delete the view and template steps assuming I can render a partial directly from the action?

Hello. I'm having some trouble with binding.pry in an Action ... If I place a binding.pry breakpoint inside of handle, the pry output is displayed in the hanami server console output, but it does not provide an interactive repl, and the execution constinues without actually breaking. Any thoughts as to how I can get an interactive REPL from a breakpoint within an action?

:point_up: Hanami 2 application

Hello,

Is there any know issue with Hanami 2.0 about 405 Method Not allowed error for routes defined with PATCH and DELETE? For e.g.
I defined following routes

scope "doctors" do
  patch "/:id", to: "doctors.update", as: :update_doctor
  delete "/:id", to: "doctors.remove", as: :remove_doctor
end

and submitting my Edit form with following hidden param in it:

<input type="hidden" name="_method" value="PATCH">

my request doesn't end up in my Update action and I see a 405 Method Not allowed error.

Following is the output of Rack env I obtained by putting debug statement at https://github.com/hanami/router/blob/v2.0.1/lib/hanami/router.rb#L101.
It can be seen in that the REQUEST_METHOD is received as POST instead of expected PATCH for route doctors/1.

I have found fix for hanami/api#29, PR: hanami/router#248

@/all I have built a startup template web application based on Hanami 2.0. The application has CRUD operations implemented for a model (or business entity) and the CRUD operations are accessible through a front-end. The repository can be found at https://github.com/jiggneshhgohel/startup_template. In the README.md in that repository I have added all necessary details. Hoping that this effort will help anybody wanting to start/experiment with Hanami 2.0 avoiding any boilerplate setup. This is a courtesy contribution of mine to the awesome community. Thanks.
