@lonniev berg is pretty big so I agree with @gotar that it could feel overwhelming a bit
We just need a Todo app or a blog app examples. Something very basic but complex enough to show off some important features

@dnd
is there any kind of built in predicate to check whether a field is true or not? I have a form that has a valid? method, and rather than make a custom predicate or something, I was hoping something already existed to do it in a generic way
Christopher Dennl-Ortega Arrieta
@cdennl
or do you mean truey?@dnd
truey? doesnt exist built in
Piotr Solnica
@solnic
@dnd there’s bool? and true? and false?
@cdennl no need for truthy/falsy because coercion will turn values into booleans prior validation :)
Christopher Dennl-Ortega Arrieta
@cdennl
@solnic I know, was just a reply to dnd

@dnd
@timriley yeah. true? was what I was looking for. I needed to nest the schema, and I just brainfarted. Thanks

If there are any dry-view users here, you might be interested to check out dry-rb/dry-view#18 - it should hopefully make a big improvement to those #locals methods that might’ve become sprawling in a few places

Happy New Year all. After a few days away, I am returning to look at dry-web. I came across the dry-web-skelton raygun template. This seems to be a good way to "terraform" an empty directory into a new project planet ready for app colonization. While I begin to grok the piece parts of the dry-rb ecosystem, I'm still wary to start just adding files here and there while not sure of the expected conventions. Is there a dry-web-roda generate entity MY_NEW_ENTITY generation script that helps one seed a new entity into the terraformed directories? For example, if I have just raygunned out a new dry-web-roda app from the skeleton, what's the next step to, say, add a route and view for a first-pass-do-nothing entity of "Tweets"? (This is likely all very evident for someone very familiar with the whole stack, conventions, and traditions but isn't evident to a newcomer or, at least, to me.)

@lonniev I've been switched off over Christmas and new year, returning this week!! I've got a couple of demo apps that use trailblazer 1.0 and dry-validation. Reform/Rom integration is a work in progress at the moment. You should check out the trailblazer channel and see if anyone has any working Rom examples. Also if your only just starting out definitely checkout trailblazer 2.0. It's awesome as is its creator @apotonick :heart_eyes_cat:

@lonniev
@fran-worley My angst is that I have to compare and contrast all the competing frameworks to try to spot what I gain or lose by working with one versus the other. I like the dry-web-roda, dry-system, dry-transaction, and rom-rb piece parts. Do I lose one or more of these if I choose TRB to get some convention? Or are we talking about supersets here where TRB is everything I find in dry-web-skeleton plus the crutch of convention that I seek? Am I afraid to adopt the very thing I seek?
Fran Worley
@fran-worley
Trailblazer isn't a framework in itself so you should be able to adopt what you please. The caveats being that currently we don't officially support ROM and you might find that dry transaction and trailblazers operations are so similar that you choose one or the other.
Lonnie VanZandt
@lonniev
Often, the best way is to just try something. TRB has a nice set of documentation and even an ebook. Is there a just-do-it raygun template or gem or thor generator that populates an empty directory with all of TRB2 and its starter app? I want the live local code so that I can simply surf that code rather than working through the hard reading and mental assimilation process.
Lonnie VanZandt
@lonniev
BTW I come to the party without Rails baggage and with no intention of first adopting Rails. Reading a bit, I see that the typical use case for TRB is a developer already using Rails, wanting to improve their situation. I'm in a green field looking for a way to explore dry-web, hoping to avoid ActiveRecord. This is why I'm looking around for the dry-web-roda entity or TRB generators.

@mindseyeblind
So I'm in the process of converting my Rails stack to use dry-validations, and I just had one question: how do I handle conditional validations? Do I just use an if block?
Christopher Dennl-Ortega Arrieta
@cdennl
@lonniev Im using Rails + TRB2 + Dry-v, using sequel instead of AR and using Cells instead of AV
Fran Worley
@fran-worley
@lonniev trailblazer is not a framework in itself, rather it's a series of gems - the main ones being Reform - form objects, operations to make sense of business logic and processes (similar to dry transaction) - that you can incorporate what you want and need into your project whatever your framework or ORM. I've got apps in Sinatra that use elements of trailblazer and an app (no framework so to speak) that uses Roda for routing, Sequel as an ORM, dry-validations and types for validations and coercions with trailblazer gems to bring it all together.
@lonniev hey, we won’t have generators for things like entities mostly because dry-web is not a full stack framework that ships with such concepts
we can have generators for some things though, like roda routes or transaction skeletons

@lonniev could you start a thread on discuss.dry-rb.org? it’s a better place to ask such questions

Hi dry! Looks like I've got some reading to do here...
Newbie Q: Is there anything such as justinfrench/formtastic#1197 as part of the dry collection? If not are there show stoppers in intergrating them?
Tim Riley
@timriley
@paradisaeidae Looks lke Formtastic is built for Rails. We don’t have our own form builder gem right now, but there are ones like Reform that integrate fairly well with dry-rb gems like dry-validation.
MarkT
@paradisaeidae
Thanks Tim!
Looks like there are some options: "Many are successfully using other ActiveModel-like ORMs and objects (DataMapper, MongoMapper, Mongoid, Authlogic, Devise...) but we're not guaranteeing full compatibility at this stage. Patches are welcome!"
Christopher Dennl-Ortega Arrieta
@cdennl
@paradisaeidae trailblazer formular is a nice form builder gem which works nicely with dry-v (and reform), I use it by myself and it is developed by @fran-worley

@georgemillo
dry-web-roda generate app admin
No value provided for required options '--umbrella'
what is umbrella supposed to be?
ohhh wait I see
the name of my parent app so it knows what namespace to wrap things in
(right?)
George Millo
@georgemillo
second mystery: I managed to generate my Admin app, but couldn't figure out how to actually get it mounted in my roots
got it working now by editing system/my_app_name/application.rb to the following:
module MyAppName
  class Application < Roda
    route do |r|
      r.on 'admin' do
        r.run Admin::Application.freeze.app
      end

      r.run Main::Application.freeze.app
    end
  end
end
am I doing it right?

@georgemillo looks good to me

third mystery: how did I manage to misspell 'routes' above, when I have to deal with that word all day every day as a web developer?
I don't know how to English

I’m a bit confused with Dry Struct….

It used to be in drytypes: Dry::Types::Struct now its on its own so change to Dry::Struct, right?

What stupid thing am I doing here:

class CreateClientForm < Dry::Struct
  module Types
    include Dry::Types.module
  end

  attribute :name, Types::Form::String
end

which appears to not find “String” constant…

specs in dry struct do:

attribute :name, ‘coercible.string’
is this how I should change things?

Maybe this should be Types::Coercible::String ??
that seems to work… hmmm

I just assumed all ‘form’ values here so use that, but perhaps I should read more closely descriptions of each….

Adam Davies
@adz

…in
http://dry-rb.org/gems/dry-validation/comparison-with-activemodel/
trying to understand

    option :account
    def unique?(attr_name, value)

and how it’s params line up with

schema.with(object: user_account).call(input)

1) is that ‘object’ key special? I thought it would be ‘account’
2) i guess that the ‘unique?’ method gets curried, so ‘value’ comes in…
but a little down”
required(:email).filled(scoped_unique?: :email, scope?: { active: true })
seems to pass in as a key “scope?:” but receive it as a positional arg… ok i guess… if i have it straight

Adam Davies
@adz

Just to report back… seems like that doc is wrong. Probably was specialised for ‘account’ then generalised to ‘object’ but not fully.

I think it should be something like:

      option :record

      def unique?(attr_name, value)
        record.class
        .where.not(id: record.id)
        .where(attr_name => value)
        .empty?
      end
