Is it possible to have raw sql like this:

  def find_by_segment_match(source_text_for_lookup, source_lang)
    segments
      .read("set pg_trgm.similarity_threshold TO 0.4;
      SELECT *, SIMILARITY(segments.content, '#{source_text_for_lookup}') AS similarity
      FROM segments
      JOIN translation_records
      ON segments.id = translation_records.source_segment_id
      LEFT JOIN segments AS target_segments
      ON translation_records.target_segment_id = target_segments.id
      WHERE segments.language_id = #{source_lang} AND segments.content % '#{source_text_for_lookup}'
      ORDER BY segments.content <-> '#{source_text_for_lookup}';").map_to(Segment)
  end

and to map it to a entity, in my case Segment. I wanted to use raw sql since I have trouble implementing the LEFT JOIN with Hanami.

How do you go about installing Hanami 2 using gem?
Brandon Weaver

Ohai. One thing that I was always tempted to try for Rails was making a lighter-weight RuboCop AST code migration tool to automate most of the upgrades for folks.

Would that be of much interest here?

Hey friends. Is Hanami suitable for apis? I was pointed to use https://github.com/hanami/api on Twitter but I'm not sure if this is an addon to hanami or a replacement.

I have a question. How do you reset the database in the test environment? I've run into a situation where subsequent tests written while following the tutorials fail because of a Unique constraint on a table.

Regarding my above question of mapping to another entity, I've posted a bit more detailed use case and problem description here: https://discourse.hanamirb.org/t/complex-joins-and-raw-sql-query-problem/687/2. Could someone check and confirm that I'm doing something wrong or is this an issue to report? In short, I need to map a query result to another entity or a Dry::Struct.

@sebastjan-hribar
Just found this workaround: I setup a placeholder entity with a repo and read the raw sql there. It's a prototype so I'll post my answer when I have it fully working.

Hi , I've ran this migration, which completed without errors, but when I run the server below:

Hanami::Model.migration do
  change do
    alter_table :segments do
    add_column :ts_content1, :tsvector, generated_always_as: [to_tsvector: [:simple, :content]]
    end
  end
end

Error:

Hanami::Model::Error: missing attributes in ROM::Relation::Name(segments) schema: :ts_content1

How can I debug this?

Sebastjan Hribar
@sebastjan-hribar
Basically, I can't use inferred schema and I can't use custom schema, since tsvector is not supported data type. Any way around this?
It's frustrating since we're loosing on performance.

Hi!

I'm having Content Security Policy problems with the Hanami 2 template project. Anyone here that could give a hint on what's wrong? :)

I'm trying to getting started with Hanami. We're hopefully going to use it in a new client project soon so we thought we should have a go and see if we can get it up and running.

I'm using a quite recent version of the Hanami 2 template https://github.com/hanami/hanami-2-application-template. I have a slightly different tool set than the one suggested in the readme. So I'm starting the project with the following:

./bin/install hello_hanami
yarn
yarn run start
# in another shell
bundle exec guard --no-notify --no-interactions

The asset server is up and running at localhost:8080. The application server is also up at port 3000 and displays correct content, but it doesn't load any assets. I get errors regarding the Content Security Policy:

Content Security Policy: The page’s settings blocked the loading of a resource at inline (“default-src”).
Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).
Content Security Policy: The page’s settings blocked the loading of a resource at http://localhost:8080/assets/main/public.css (“default-src”).

Hi, I am trying to use Hanami for a production-based API solution. I would like to know if there is any template for API? Something like the web version https://github.com/hanami/hanami-2-application-template. Or are there any thorough resources you want to point me to regarding making API with Hanami?

I'm having some issues trying to utilize a params block in an Action within hanami-2-application-template. If I include the block, I receive an error: NoMethodError: undefined method 'params' for Main::Actions::Characters::New:Class

... digging into the code a bit, it appears that Hanami::Action:Validatable, which includes the params(klass = nil, &blk) definition, is only included in Hanami::Action::StandaloneAction (which itself is included in Haname::Action) if Validatable is already defined: https://github.com/hanami/controller/blob/v2.0.0.alpha6/lib/hanami/action/standalone_action.rb#L55

...it seems to me I just need to add the correct gem to my Gemfile, or require the right library file (hanami/action/validatable?) in the right source file, or something simple like that.

Any help?

I have a question about the Hanami.application global. After digging through the code and testing it seems like this way of keeping a global reference to the app means that you can have only one Hanami instance running at once? So if I wanted to run two Hanami apps mounted at different paths in Sinatra, could I?

I'm not asking because I have that particular use case, but I am trying to solve some of the same problems that Hanami have solved and this is the final thing I'm stuck on. It might not be a problem for Hanami - normally you would just run a single instance anyway. But I'm building a REST API abstraction library and this global reference (if I understand it correctly) means that end users would not be able to have two API libraries based on my abstraction loaded at the same time - they would both try to use the global and get into a conflict, the same way you would if you tried to load two Hanami apps at once now.

Or am I missing something? :slight_smile:

hi, I was wondering if there's still an effort for service object, I remember there was Hanami::Interactor some time ago. but I can't find it in the 2.0 version
Lairan
@alex-lairan

@greenfork Prefer real object domain instead of procedural "service object".

Hanami 2 has a very simple way of creating a rich domain thanks to dry-system.

@alex-lairan thanks, that is new to me! controversial topic indeed :)

@greenfork check out dry monads. I think this is what you searched for.

@alex-lairan Hanami still recommends the functional service object approach, right?
David Silva
@Davidslv
Hello all, I never have used hanami before but today is the day I'm giving it a try. Right now I only have one question: is it possible to start a new project without having mailers added by default? Or should I just delete code, folders and files (is it ok to do that?)
I was hoping I could just do it through the new command like I did with the rest of the options: hanami new pistachio --test=rspec --database=postgres --template=erb
Seb Wilgosz
@swilgosz
@Davidslv If you are trying it for the first time, I would suggest to try Hanami 2 app template. We have view helpers and cli generators missong yet though.
Lairan
@alex-lairan
@wuarmin rich domain does not mean no functional
it means the domain can handle itself without app (controller) and infra (repo/relations)
So thank this you can unit test all your domain without any mock db
Armin
@wuarmin
@alex-lairan rich domain model means that the models contain the logic, right? Anemic model domain means that the models are only data holders that are changed by e.g. service objects. I like the Anemic model domain approach: The side effects happen in the service-objects and the domain can handle itself too. The logic is in the service-objects (synonym of interactor) and the models are passed as parameters. A controller just calls the service-object, e.g. UpdateUser.new.call(user). With this approach you can also unit-test the domain without mocking the db.
Lairan
@alex-lairan

rich domain model means that the models contain the logic

Not in a functional way, you have your data and the module logic is the "owner" of this data.

That is how the rich domain is represented in functional.

Hanami allows us to design our code, takes all the advantages you can.
That's a big step comparatively of Rails that forces us in a MVC + RailswayTM

I'm wandering back into ruby (and looking hard at elixir) after a very long absence. I remember reading a few articles back then that outlined a "better" approach to programming for the web than MVC.. I remember reading that and thinking wow.. they're on to something there.. something that was a lot different than rails but more natural to what the web actually is.. and therefore more performant.. I remember that led me to dry-rb and hanami.. So I guess I'm looking for those type of articles or blog posts again to refresh my memory.. Can anyone point to anything? Maybe this was 2016 or 2017..
zhando
@zhando
I believe the articles or blog posts back then may have mentioned roda as part of this newer approach..

@zhando Perhaps "Railway oriented programming"? Or "Hexagonal Architecture" (though the whole point of that is that it's not web specific)
Damian C. Rossney
@dcr8898_gitlab
@zhando Here's a bunch of links for you! ;-) To start with, taking a bird's eye view of architecture, you might want to read about Hexagonal Architecture (original article by Alistair Cockburn is currently available from the Internet Archive or Wikipedia); or Onion Architecture; but similar ideas are laid out most clearly by Robert C. Martin in his presentations on Clean Architecture (article and excellent talk--you can find other versions of this talk).
Damian C. Rossney
@dcr8898_gitlab
@zhando More specifically, I think you were probably referring to the posts by Tim Riley, now a Hanami and Dry-rb core team member. I would try to read everything he has written, along with anything by Piot Solnica. Here is an article by Tim Riley (possibly the one you are thinking of) and a talk. Here's a dose of Piotr Solnica, but you can read a lot more there. Here's a recent talk he did on Hanami. Obviously, you should seek out talks and articles by Luca Guidi as well.
@zhando It seems clear that Hanami was influenced by Hexagonal/Clean Architecture, both in its approach and the terms it uses (interactors, entities, gateways). Not that these terms are unique, but they are used in Hanami in a way that is consistent with the ideas brought together by Robert C. Martin in his material (he does not claim to be the creator of any of these ideas, but distilled them from several sources to propose a general approach). Good luck!
zhando
@zhando
Thanks everyone! Excellent..

And the Tim Riley articles had to be some of what I was reading back then. Thanks again.
