@sebastjan-hribar

This is my first part of my yesterday's question. I've removed the gem list:

I'm experiencing a really odd issue. I'm getting TypeError at no implicit conversion of Integer into String for this line: session[:session_start_time] + @validity_time.to_i < Time.now. This started on a development branch where the only change that might impact this is the gemfile or gemfile.lock. On master, session[:session_start_time] is a NilClass and on the development the session[:session_start_time] is a String class. I did delete the gemfile.lock on the development and ran a fresh bundle install. The session[:session_start_time] is set as Time.now.
I've checked Tachiban and irb for the comparison and it runs fine, as well as on the master branch.

Now for the solution:
I've found the culprit. It was hanami 1.5.0. Reverting it back to hanami 1.3.0 solves the problem. Now I don't know, does this qualify for an issue for Hanami or Tachiban?

This issue in hanami-api about using scope with path parameters feels a bit lonely. hanami/api#29
Maybe you can leave a comment what you think about it? Do you think it's valid?

Yo guys, quick question. Does hanami2(rom, sequeel) support psql yet?
When I run:

bundle exec hanami db create_migration apples

I get:

/src/vendor/bundle/ruby/3.0.0/gems/hanami-cli-2.0.0.alpha3/lib/hanami/cli/commands/db/utils/database.rb:32:in `block in []': psql is not a supported db scheme (RuntimeError)

Hi, where do partials take context from? What I need exactly is iterate over an array in a template and use partial to render the individual element with context inside that cycle. How do I do that? I didn't find any references to that in docs but only to using partials on their own.

How do I get the id for foreign key without calling find on that association? I have video belong to location. If I call video.find(id) I get both .location and .location_id to be nil and I can't do a consecutive location.find because of that. How do I do this?

1 reply

I don't use aggregated call for that because I need to extract info from 2 associations and apparently you can't do 2 calls like aggregate(:location).where(id: id).map_to(Video).one in a single call — one of them doesn't seem to update parent object. or am I doing something wrong with this?

class VideoRepository < Hanami::Repository
  associations do
    belongs_to :location
    has_one :video_info
  end

  def find_with_location(id)
    aggregate(:location).where(id: id).map_to(Video).one
  end

  def find_with_info(id)
    aggregate(:video_info).where(id: id).map_to(Video).one
  end

  def find_with_info_and_location(id)   # this function doesn't populate location nor location_id
    aggregate(:location).where(id: id).map_to(Video).one
    aggregate(:video_info).where(id: id).map_to(Video).one
  end
end

Hanami::Model.migration do
  change do
    create_table :videos do
      primary_key :id

      foreign_key :location_id, :locations, null: false
    end
  end
end

Hanami::Model.migration do
  change do
    create_table :locations do
      primary_key :id
    end
  end
end

Hanami::Model.migration do
  change do
    create_table :video_infos do
      primary_key :id

      foreign_key :video_id, :videos, null: false, on_delete: :cascade
    end
  end

Hi everyone, first time here and with a question! I am trying to integrate Webpack (with Babel) for react using the hanami-webpack and hanami-assets gem, but I got into some trouble with import statements.

In my application.html.erb file, i use the <%= javascript 'index' %> helper that points to my index.js file in assets, which works fine when it's pure Javascript and does not have any import statements. However, when i try to import React, it throws an error: "Uncaught SyntaxError: Cannot use import statement outside a module"

One of the solutions i found online is to put "type"="module" to package.json to ensure that all .js files are seen as modules and not CommonJS - I tried doing it, but it lead to another error with my Webpack.config.js file, which is using 'require' instead of import. I changed the file extension to Webpack.config.cjs, which resolved the error the server was throwing, but I am still stuck with 'Cannot use import statement outside of module'

Does anyone know how to solve this? Is there a good example of how to integrate React with Hanami? Thanks!

Hey everyone, hope you are enjoying your holidays - just fyi, after several days of tinkering with trying to integrate React as the frontend with Hanami, I came up with a basic setup that I am hoping is useful to see for anyone who is new and would like to do the same thing - I gave up on Webpack because it was unnecessarily complicated, could not get hot reload to work and the compile times were pretty long - so I used ESbuild instead. Here is a repo with a template you can use: https://github.com/glemin5011/react_on_hanami

Just be aware that it does not have any installer or anything, so things such as .env files etc. are not really transferrable to new projects - this repo is more of a demo / guide

Edit: This is for Hanami v1.3.5

Hey, I have this code in the views/application.rb:

def current_user_roles
      UserRepository.new.find(session[:current_user]).roles
 end

where the current_user is the user's ID. However, the view has no access to the session. How can I bypass this? The use case is limiting the displayed items as per user roles.

Hey Hanami experts, I've just cloned the template repo for Hanami 2, followed the steps for setting up, but when it came time to setup a new migration, I ran into the following error:

`method_missing': undefined method `session_secret' for #<Hanami::Application::Settings:0x000055af322964b8 @config=#<Dry::Configurable::Config values={}>> (NoMethodError)

If I run precompile before the build and don't run precompile with compose then I get the Internal Server Error.
If I run precompile in a running container the assets are again not served.

I have the option to serve static assets set to true in my .env.production.

I am really expecting a lot from Hanami 2.0 and I am willing to use it right now. Do you think I can use it for 4 now?

For a personal use (where service can be stopped for a week)
For a community with known people (where service can be stopped for one day)
For a within-company communication tool (where service can be stopped after work)
For a large community with unknown people (where service can be stopped for a few hours)
For a service to customers (where service should not be stopped)

My concern is whether Hanami 2.0 updates are what Hanami 2.0 users can follow. Is there any way for Hanami users to follow API changes and directory structure changes? But some people are already using V2 for production apps, which means my concerns are just concerns.

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.
