Re: [Rails] finding function defenition

[Ariel Juodziukynas]

One thing you can do is use a gem like byebug, put a breakpoint above the
code you want to find it's location and use this:

method(:name_of_method).source_location

if you put a breakpoint inside your routes.rb and call:

method(:get).source_location

it returns something like:

./gems/actionpack-6.0.2.2/lib/action_dispatch/routing/mapper.rb, 711

Than you can check the source on github

https://github.com/rails/rails/blob/v6.0.2.2/actionpack/lib/action_dispatch/routing/mapper.rb#L711

It doesn't always work, you can have methods generated on the fly using
define_method for example I'm not sure source_location gives you the right
source there.

Re: [Rails] On polymorphic associations with has_many through, is it possible to pull in multiple source types with one query?

[Ariel Juodziukynas]

I'm not sure if you can have all that with a single AR query, I think you
need a custom query (I would use a UNION query an I think AR doesn't
support that)

Re: [Rails] Is it worth switching to Postgresql?

[Ariel Juodziukynas]

Sorry, using different db on different environment is not something I'm
recommending, it was just to point out that the transition should be really
easy. I do think it's faster to prototype using sqlite as long as it fits
the needs, but in a more mature projects I would use the same db everywhere
so I can use all the features I need.

I didn't have that many projects with postgres to talk about upgrading
versions and those things, but personally I never had issues with MySQL
either.

About encodings and collations, I guess it depends on the error but if you
have encoding or collation errors I guess the problem is the configuration
of your tables and the input and not the actual db, you may encounter
problems with any db if you try to handle incompatible encodings at the
same time.

I've used PgAdmin, but didn't try others to compare or recommend anything.

One more thing you can do if you don't want to struggle with updates,
version, etc, is to use docker maybe, you just run the image on any system
and you can replicate the actual production environment anywhere.

Re: [Rails] Is it worth switching to Postgresql?

[Ariel Juodziukynas]

Usually ActiveRecord takes care of most of the differences, and
postresql has a lot of similarities with mysql. I guess it would be a
different call if you ask about learning a completely different db engine
like mongo or graphql, but learning postgresql shouldn't take too much time
knowing MySQL, at least to be proficient. I even have a project that I used
sqlite to prototype and postresql when deploying it to heroku for tests and
I had to do nothing to make it work on both databases thanks to AR.

Also, heroku prefers postrgres for example and heroku is really popular for
rails hosting.

Each worker runs on a process. When you run the "ps" command on linux

Re: [Rails] Why do basic forms not work in Rails 6 without binding events to each form?

[Ariel Juodziukynas]

I understand your complain, what I'm saying is that I have some rails 6
projects using form_for remote and form_with and I didn't have to bind to
the ajax events. rails-ujs and jquery_ujs both expect you to render a view
with .js format and both libraries executes your response's javascript.

Are you rendering a js view when you process the unsubscribe action? what
does you action do? what do you respond to the user from your server? you
have to tell rails what to do when you submit the form, how are you telling
rails what to do?

Re: [Rails] Why do basic forms not work in Rails 6 without binding events to each form?

[Ariel Juodziukynas]

I have a few rails 6 projects and remote forms works out of the box with no
event binding. Can you reproduce that problem with a clean rails app? maybe
you have some other js messing up rails' ajax handers.

Re: [Rails] do i need associations to use fields_for

[Ariel Juodziukynas]

accepts_nested_attributes_for explicitly checks for associations to exist
https://github.com/rails/rails/blob/f33d52c95217212cbacc8d5e44b5a8e3cdc6f5b3/activerecord/lib/active_record/nested_attributes.rb#L340

fields_for does not require accepts_nested_attributes_for to be defined,
but it won't behave the same without that, you can inspect the generated
html on both cases

Re: [Rails] Why do basic forms not work in Rails 6 without binding events to each form?

[Ariel Juodziukynas]

It doesn't say you that you HAVE to bind all the ajax events. It explicitly
says that you "probably" want to do that if you "probably" want to do
something other than just submitting the form.

Re: [Rails] how do i append an image to a dom element using javascript

[Ariel Juodziukynas]

The client part requires javascript, the backend part requires no
javascript, I strongly recommend you read this
https://guides.rubyonrails.org/action_cable_overview.html

Sometimes it looks like you just ask questions without reading about the
subject you try to use. The official guide shows you what file goes where.

Re: [Rails] activestorage user.avatar.attached? in javascript

In your case, you CAN'T call "user.avatar.attached?" inside
app/javascript/channels/room_channel.js.erb because it's a request
dependant object.

Re: [Rails] activestorage user.avatar.attached? in javascript

[Ariel Juodziukynas]

Although you can use .js.erb extension for any .js file you have to
understand WHEN that erb gets executed to understand what you can do with
it.

Assets with .erb extension are compiled to JS code during the assets
precompilation process, you can't put request dependant code (current_user,
instance variables, request controller/action, etc) inside an .js.erb asset
file because it's an isolated process (assets are compiled into one final
static .js bundle).

You can put request dependant code on .js.erb VIEWS because views are
executed when they are needed for each request.

Not all js files are used the same way, you can use .erb extension to have
ruby code but have to take into account the context to understand what
variables you have access to.

[Ariel Juodziukynas]

You can't, you need the .erb extension to execute ruby code.

Re: [Rails] //= require stylesheet with webpacker

[Ariel Juodziukynas]

"//= require ..." is Sprocket's syntax (most known as rails' assets
pipeline), not webpacker's. If you really want to handle CSS assets with
webpacker you should start by reading this
https://github.com/rails/webpacker/blob/master/docs/css.md

Re: [Rails] ActiveRecord find ignores extra characters after numeric id. ?

[Ariel Juodziukynas]

I guess you are calling ensure_canonical_url before_action BEFORE
set_blog_post before_action, so it's not already set.

I guess you have something like:

before_action :ensure_canonical_url, only: :show
before_action :set_blog_post, only: :show

swap both lines if so.

Re: [Rails] ActiveRecord find ignores extra characters after numeric id. ?

[Ariel Juodziukynas]

I insist, show your code, show the complete error stacktrace, show the log.
I can imagine what you are trying to do and from the (little) code you show
it should work so something else is messing things up but you are showing
barely any relevant code.

Re: [Rails] ActiveRecord find ignores extra characters after numeric id. ?

[Ariel Juodziukynas]

find method doesn't care about the to_param method, it just takes the
parameter you use, I guess it calls "to_i" and uses that integer to query
the id column

Why don't you show your code, the stacktrace, the logs or anything? I
suggest you read something like stackoverflow's guidelines on how to ask,
you posts are usually really hard to understand and a lot of information is
missing

Re: [Rails] ActiveRecord find ignores extra characters after numeric id. ?

[Ariel Juodziukynas]

>From the docs:
https://apidock.com/rails/v6.0.0/ActiveRecord/FinderMethods/find

Person .find
("31-sarah")
# returns the object for ID = 31

In your case, if you are using find, it should search for record with id =
18

Re: [Rails] how to pass data to javascript in div.content_tag

[Ariel Juodziukynas]

data attributes (data-something on an html tag) are accessed using the
"dataset" property of javascript's HTMLElement element
https://developer.mozilla.org/en-US/docs/Web/API/HTMLOrForeignElement/dataset
, that "received(data)" sounds like a callback from a promise or ajax call
to me, that's a totally different thing.

Camel case has two variants: first letter can be lower or upper case (camel
case with capital first letter is also known as PascalCase)

I respond via emails, I guess you delete the post on the google groups page
but the email is already sent.

Re: [Rails] how to pass data to javascript in div.content_tag

[Ariel Juodziukynas]

No, the first line is ruby and the convention is snakecase so it's ok you
use underscores, the second line is html and the attributes syntax is
hyphen, when you access that data attribute with javascript it will be
dataset.conversationWithId as camelcase. You should write using the
convention of the language you are using, then each language takes care of
converting it.

Re: [Rails] Re: [rails] devise-in18n messages not localized

[Ariel Juodziukynas]

>From the code you can see it uses internationalization
https://github.com/plataformatec/devise/blob/098345aace53d4ddf88e04f1eb2680e2676e8c28/app/controllers/devise_controller.rb#L182

You can do something like this on an initializer so override the I18n
lookup method to print each key it tries to find, maybe you can
debug what's going on:

# config/initializers/debug_18n.rb

module I18n
module Backend
class Simple
# Monkey-patch-in localization debugging
# Enable with ENV['I18N_DEBUG']=1 on the command line in server startup, or
./config/environments/*.rb file.
#
def lookup(locale, key, scope = [], options = {})
init_translations unless initialized?
keys = I18n.normalize_keys(locale, key, scope, options[:separator])

puts "I18N keys: #{keys}"

keys.inject(translations) do |result, _key|
_key = _key.to_sym
return nil unless result.is_a?(Hash) && result.has_key?(_key)
result = result[_key]
result = resolve(locale, _key, result, options.merge(:scope => nil)) if
result.is_a?(Symbol)

puts "\t\t => " + result.to_s + "\n" if (result.class == String)

result
end
end
end
end
end

I don't rember where I took that code from to give the credit.

Now you can check that's actually trying to translate (from the code it's:
some_resource_name.some_message)

Re: [Rails] rails 6 where to put javascript files

[Ariel Juodziukynas]

If you have a file inside /packs called application.js that has a line
"import Something from '../some_js'", webpacker will include the code from
"some_js.js" inside the resulting bundle "application.js".

Re: [Rails] bootstrap nav vs div class: nav

[Ariel Juodziukynas]

The "nav" tag provides more meaning, I guess bootstrap just checks the
class "navbar" so it doesn't care if you used a div or a nav, but in terms
of semantics, a nav tag if better for a navigation bar as the name suggests.

Re: [Rails] rails 6 where to put javascript files

[Ariel Juodziukynas]

There's a section specifying where to put js files on the documentation
https://github.com/rails/webpacker#paths. You can put the files anywhere,
if you put them inside the packs folder webpacker will create bundles using
those files, if you put them elsewhere wenpacker will bundle them inside
the packs that require them.

You shouldn't have files inside pack except for the bundles/packs you'll

Re: [Rails] Re: access images in stylesheets with webpacker and rails 6

[Ariel Juodziukynas]

Webpacker provides an `asset_pack_path` method
https://github.com/rails/webpacker#usage

I guess you'll need to use a .css.erb file in order for that to work.

# something.css.erb

.search_button {
  background: url('<%= asset_pack_path('images/search.png') %>');
}

Lately you are asking A LOT of questions about webpacker for images and
CSS, you don't really HAVE to change from Sprockets to Webpacker to update
to rails 6, in fact, if you start a new rails app, it uses webpacker only
for javascript assets, it's still using sprockets for css and images by
default. Of course you are free to use webpacker for everything but maybe
you have to follow webpack guidelines and start messing with loaders, check
the webpack guide on packing images and using it for background image for
example https://webpack.js.org/guides/asset-management/#loading-images

Re: [Rails] No folder under node_modules after install packages with yarn

[Ariel Juodziukynas]

Yarn creates the folder on the directory you run that command. Also it's ok
the folder is not inside the packs folder, webpacker creates bundles for
any file inside the packs folder, you shouldn't have files other than the
packs/bundles you'll link on your html.

Re: [Rails] snippet duplicates fields x 8

[Ariel Juodziukynas]

I'm not really sure what's your intention and what's the state of the @item
instance. And I have to admit your namings are really confusing
"item.item_item_properties" looks too repetitive, are `iip` and
`item_item_property` on both loops the same class? does @item have all the
item_item_properties?

I think I would do

<%= f.fields_for :item_item_properties do |iip| %>
  
<%= iip.label iip.item_property.name
<http://item_item_property.item_property.name/> %>
<%= iip.hidden_field :item_property_id, value: iip.item_property_id %>
<%= iip.text_field  :text_value, value: iip.text_value %>
  
<% end %>

But I'm not sure that's your intention.

Also, a TD inside a DIV is not valid HTML, it will brake your template

Re: [Rails] snippet duplicates fields x 8

Your form_for uses the @item? if so you are already looping through it's
item_item_properties, yo don't need to loop again inside fields_for, you
already have iip defined, that's why you have everything multiplied

Form_with does an ajax request by default, use form_for or add local: true
as an option or respond with a js view.

The form looks ok, the parameters on the request too, it's impossible to
tell you something else if you have nothing on the logs (rails and the

Re: [Rails] form not loading for get request

[Ariel Juodziukynas]

It's normal that rails adds a hidden field with the name `utf8` and a check
as the value, when you submit a form using GET the hidden field goes there
with the other fields, there's nothing wrong there.

You should have some error on the console if something is not working, that
`utf8` parameter is ok.

Re: [Rails] How do I load schema in rails 6

[Ariel Juodziukynas]

What do you mean that you have an error en your schema.rb? When you run a
migration, rails dumps the current database schema (rails db:schema:dump).
Maybe you have some merge conflict if you are using source control and
someone fixed the conflict wrong, but the file shouldn't have errors since
it's just a dump of the actual running database's schema.

You have all the db: tasks (run `rails -T | grep 'db:' to list all)
including running the migrations, those are the only commands to change
your database schema using rails.

Re: [Rails] How do I load schema in rails 6

[Ariel Juodziukynas]

You were trying to reload the schema, db:schema:load requires an empty
database, I guessed you were OK with removing the data. db:reset it's just
a shortcut for drop > create > schema:load > seed.

Why do you want to load the schema if you already have data and you don't
want to lose it? that makes no sense, if you already have data then you
already have the schema loaded.

Re: [Rails] sass-rails

[Ariel Juodziukynas]

sass/scss files shouldn't be linked by your website, these files have to be
compiled into standard .css files with sprockets, webpacker or any other
sass compiler.

Usually, if you use sass-rails (or sassc-rails on newer rails version) or
webpacker, both gems should take care of compiling the assets for you with
proper configuration.

Re: [Rails] where do i put rails 6 stylesheets

[Ariel Juodziukynas]

Rails 6 supports both sprockets (the assets pipeline) and webpacker by
default, you can use any of those. You can use app/assets/stylesheets as of
previous rails versions that didn't have webpacker or you can follow
webacker's readme on CSS
https://github.com/rails/webpacker/blob/master/docs/css.md

Re: [Rails] build with nested forms

[Ariel Juodziukynas]

@item.item_item_properties.item_property_id is wrong,
@item.item_item_properties is a collection, use `
iip.object.item_property.name` and `iip.object.item_property_id` instead.

imagine @item.item_item_properties is something like an array
[item_item_property1, item_item_property2], you can't call
`item_property_id` on an array, you have to call it on one of the items
inside it, and that "iip" variable, if you call `.object` on it you get
that item from within the array.

Re: [Rails] need help with carrierwave - multiple vs single file upload

[Ariel Juodziukynas]

If you need extra fields for each attachment then you need an extra model
to store that data and the carrierwave file for each file you upload. Given
the name of the model "FolderAttachment" it looks like that's the model and
that it shouldn't have multiple files, it looks like there should be
multiple FolderAttachments with only one file each.

[Ariel Juodziukynas]

I mean: multiple files can be zero or more, it includes the possibility of
having only 1 file attached.

[Ariel Juodziukynas]

I don't think you can use the same attribute name for single and multiple
attachments at the same time. What you can do is to always have multiple
files and attach only one file when you get a single file upload. I don't
understand the use case of your idea.

Re: [Rails] need help with carrierwave - multiple vs single file upload

[Ariel Juodziukynas]

I think your problem is here

<%= form.file_field :files, multiple: true, name:
"folder_attachments[files][]"  %>

use "folder_attachment[files][]", note "folder_attachment" singular, not
plural since the form is for a single folder_attachment (and that's on your
folder_attachment_params method)

Re: [Rails] need help with carrierwave - multiple vs single file upload

Also, use "mount_uploader" singular for the single file and
"mount_uploaders" plural for the multiple files

Re: [Rails] build method

[Ariel Juodziukynas]

If you have:
item has_many item_item_properties
item_item_property belongs_to item_property

then you can add a relationship on the item model

has_many :item_properties, through: :item_item_properties

Then you'll be able to call @item.item_properties to loop through the
ItemProperty objects associated to that Item object.

Now, you say @item.item_item_properties.pluck(:item_property_id) returns an
empty array, that's because the Item does not have associated properties
and pluck does an SQL.

Re: [Rails] build method

You can do @item.item_item_properties.each do |item_item_property| and
handle that object inside the loop, I'm not sure why would you expect that
item_item_properties relationship to return key, value pairs. I don't
understand what you want to achieve, maybe you are trying to do it on the
wrong path.

Re: [Rails] build method

[Ariel Juodziukynas]

@item.item_item_properties returns a collection of objects, you are calling
a method on something array-like, it makes no sense.

If you want to get all the item_property_ids you can
do @item.item_item_properties.pluck(:item_property_id) for example. I'm not
sure what you want to achieve.

Re: [Rails] build method

[Ariel Juodziukynas]

Use `.size` instead of `.count`. "count" does a database query and since
you only built the element the COUNT db query will return 0. "size" knows
what to do if the association is already initialized so it will return "1"
in your case (and if it's not already loaded it will run a COUNT db query).

Re: [Rails] auction site listings table

[Ariel Juodziukynas]

Read about the `fields_for` helper on actionview and the
`accepts_nested_attributes_for` macro on activerecord to handle nested
forms (fields_for to create the form, accepts_nested_attributes_for so
activerecord handles the associated objects creation).

https://api.rubyonrails.org/classes/ActionView/Helpers/FormBuilder.html#method-i-fields_for
https://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html#method-i-accepts_nested_attributes_for

Re: [Rails] error using direct path url vs ok when navigating by mouse

[Ariel Juodziukynas]

You are using `redirect_to request.referrer` and referrer is nil if you
enter the url by hand.

Use `redirect_back fallback: root_path` instead.

Re: [Rails] Internationalization of stylesheets

[Ariel Juodziukynas]

Do the style for each locale differ a lot?

Personally, I would use a class or attribute to se the language on the body
or the html element and put all languages on the same file and add the
language as the selector for the things that should be different. It the
difference is little you shouldn't have any problem with the size since
minification and gzip compression should be enough.

If the styles are too different, I'm not sure.

Do you see any error on the browser's console? first thing I notice
just simple looking at it is it's missing all the ; at the end of the
lines, maybe you have a syntax error on the browser's dev tools

Re: [Rails] upgrade to rails 6

[Ariel Juodziukynas]

You are mixing webpack with yarn. The only use of yarn is to download
javascript packages from https://yarnpkg.com/lang/en/ to your app's
node_modules folder. Webpacker is a gem that uses Webpack which is an
assets manager/packer solution similar (but with conceptually
different approach) to Sprockets (known as the rails' assets pipeline).
Both Webpack and Sprockets can use the node_modules folder to find the
required files.

You can use webpacker or sprockets on rails projects, you can even use both
at the same time, the only difference between rails 5 and 6 is that 5
defaults to sprockets and 6 defaults to webpacker *for new projects*. You
don't *have* to migrate to webpack if you don't want to, you should be able
to upgrade to rails 6 without using webpack and everything should work as
before.

Yarn won't create the /packs folder, webpacker should do that, maybe you
didn't configure webpacker correctly or you didn't run the webpacker
compiler. I suggest you follow the official webpacker guide to understand
it https://github.com/rails/webpacker#installation

Re: [Rails] upgrade to rails 6

You shouldn't need to do that, you could use yarn to manage JavaScript
dependencies with rails 5 too. Also the assets pipeline still works the
same way with rails 6, only webpacker is the default now, but you can keep
the old behaviour

Re: [Rails] how do i add rows to the associations table in a has_many_through relation

[Ariel Juodziukynas]

I think you can actually do @physician.patients << @patient on some cases
where your join model does not require anything else, but in that case it's
more common to use a has_and_belongs_to_many association instead, if you
use a has_many :through you usually want more data on the join model so you
need to use the code on the previous response

Re: [Rails] Re: get request to new action using form instead of link causes param is missing or the value is empty error

[Ariel Juodziukynas]

https://apidock.com/ruby/Hash/fetch

fetch tries to get the value from a hash given a key, the second parameter
is a fallback in case the key does not exist on the hash (params), in your
case, if params[:item] does not exist, it returns {} so the next .fetch
won't fail. now the second .fetch tries to get the value for the key
:item_type, if it does not exist y returns "false". fetch is used when you
have optional keys on a hash and you need a fallback in case the key is not
present

Re: [Rails] auction site listings table

[Ariel Juodziukynas]

You were asking a way to store different values, I thought you wanted to
preserve the type (so you can distinguish 1 from "1" when you read the
record).

If you think strings are enough for your requirements just use a string
column, if you want to use one column to store values but preserve the
original type you have to serialize the value somehow (that's the is_a?...
when serializing and the case when casting).

Another option is to use two columns: one for the stringified value and one
for the original type so you can parse that again.

Re: [Rails] auction site listings table

[Ariel Juodziukynas]

The easiest but too big is a text columns so you can use
activerecord' serialization of attributes to save anything you want on a
text field and activerecord will handle casting.

You could use a string column if you know your values won't be too big
(VARCHAR(255)) and you know what types you want to accept and handle
serialization yourself like:

def value=(something)

Re: [Rails] Re: Deep Nesting Help

[Ariel Juodziukynas]

I'm not sure I understand what's the problem, where exactly do you have
doubts?

I'd suggest you first refactor that super ugly nested loops and ifs:
- remove the unnecesarry if's
DdCategory.all.each do |category|
  # If the Category is active, build it
  if category.is_active?

can't you handle that is_active? with a scope?

- the blocks for category.dd_items and subcategory.dd_items looks almost
the same, I think you can reuse some code there

- move complex logic to other methods to clean that up, like:

item.dd_subitems.each do |subitem|
  newitem.dd_detail_subitems.create!(dd_detail_item_id:
newitem.id, title: subitem.title, has_check: subitem.has_check, has_value:
subitem.has_value, has_note: subitem.has_note, item_check:
subitem.item_check, item_value: subitem.item_value, item_note:
subitem.item_note)
end

could be a method on newitem like "add_subitem_from(subitem)" that does
that create but you'll have less clutter to simplify your logic to
understand it better

Re: [Rails] auction site listings table

[Ariel Juodziukynas]

Another option (if your database accepts it, like postgres or newer MySQL
versions) is to use a column with JSON or JSONB type. You could have a json
object with all property/value pairs. I'm not sure about performance,
indexing, etc on JSON columns though.

I'm not sure what are the categories you are talking about now, you mean
the "auction type"?

You'll have to have many many millions of auctions in order to make the
auction_properties tables too large (if your ID is an int, you have 2,000
MILLION ids to use, if you use bigint I don't even know that number, you'll
need really good indexes though haha), and even if you ever get near some
critical situation you could split table by auction type or something like
that. I doubt it's something you have to worry about right now, you'll have
a lot of more important things to improve before reaching that.

Re: [Rails] auction site listings table

[Ariel Juodziukynas]

Personally, I would do this:

auctions table
(with the basic shared information of all auctions and an "auction type"))

properties table
property_name (like network, carrier, publisher, etc)
auction_type (like cellphone, book, etc)

auctions_properties
auction_id
property_id
value

That way you can have any number of auction types with any number of
specific properties with just 3 tables.

Note that the "value" column would be some string variation (VARCHAR, CHAR,
TEXT, etc) depending on your needs, maybe you want to redesign it a little
if you want to store different types. Like if you want to store an integer
(and retrieve an integer) you'll have to save the original type and reparse
it (you could use serialization but that requires a TEXT column and maybe
you can't use that many space)

Re: [Rails] Carrierwave multiple file uploads

[Ariel Juodziukynas]

It adds the "[]" so the parameter is an array (if you don't add that,
params[:avatar] will be only one file and not an array). I'm not sure why
but the helper does not infer that, you have to be explicit on that.

`has_many_attached :files` actually sets to has_many relationships:
`has_many :files_attachments` and `has_many :files_blobs`, you could use
those has_many relationships to use on your user's has_many :through

Re: [Rails] has_many & build & first_or_create

[Ariel Juodziukynas]

I don't understand what your are actually trying to do with that.

"@p" is an instance of the Project class, "find_or_crate" is a method on
active record relations, what do you expect "@p.find_or_create" to do? I
guess you can define your own instance method on Project class to do
whatever you want

what's the use of "@pt = @p.tasks.build(params)" on your example?

Re: [Rails] Unable to connect my ruby ​​on rails APP to a SVN repository

[Ariel Juodziukynas]

You have no blank space between USER and "--password". Also add the option
"--verbose" to the comend to see more info of the request. Are you sure the
command works? I mean, I don't see how it's related to ruby nor rubyonrails.

Re: [Rails] ActionText always wraps content in

Just define your own partial in your app's app/view folder and it will be
used instead of that default partial.

Re: [Rails] @ gem cocoon - how do i

[Ariel Juodziukynas]

Let's say you have a user that has many books, if you want to hace some
book prefilled just do

@user.books.build(title: something, year: someyear)

As long as you don't reload the relationship, the books will be on the user
(just not persisted) and `fields_for :books` will iterate over them

You can give a try to my gem for dynamic nested fields, I'd really
appreciate it :D https://rubygems.org/gems/vanilla_nested (it's similar to
cocoon but weight less than 10%, and it has no dependencies like cocoon
that adds a lot of gems and depends on jquery)

Re: [Rails] Rails 5.2 Custom Credentials — generally accepted way to segregate environments?

[Ariel Juodziukynas]

H I don't know if heroku lets you add custom commands during deploy,
I've only used it for tests. If it does, you could have two files on your
source credentials.yml.enc.prod and credentials.yml.enc.dev and during
deploy just rename on of them depending on the environment you are (mv
config/credentials.yml.enc config/credentials.yml.enc). It you can't add
custom command then I don't know haha.

Re: [Rails] Rails 5.2 Custom Credentials — generally accepted way to segregate environments?

[Ariel Juodziukynas]

Rails 6 will have this feature https://github.com/rails/rails/pull/33521

For Rails 5.2, personally, I wouldn't add the file to the source control. I
would do this steps:

1- run rails credentials:edit locally
2- add the credentials for production and save
3- upload the file to your hosting at /home/user/your_app/shared/config/
4- configure capistrano to symlink that file on each deploy (at
config/deploy.rb)

set :linked_files, fetch(:linked_files, [])+%W{config/credentials.yml.enc}

Now, on each deploy, capistrano runs a task that adds some symlink to the
current release pointing to /shared so they are kept between releases. Your
file /home/user/your_app/current/config/credentials.yml.enc will actually
be a symlink to /home/user/your_app/shared/config/credentials.yml.enc. You
can just have that on production, use one on development and add it to the
.gitignore file so it doesn't conflict with the symlink.
