This method was introduced in Rails 6.0. It can be used to take an array
and create a hash where the elements of the array are the indexes of the
hash.
We were using this hack in order to allow `File.new` attachments in
tests files. However, we can use the `fixture_file_upload` helper
instead.
Just like it happened with `file_fixture`, this helper method doesn't
work in fixtures, so in this case we're using `Rack::Test::UploadedFile`
instead.
This fixes a few issues we've had for years.
First, when attaching an image and then sending a form with validation
errors, the image preview would not be rendered when the form was
displayed once again. Now it's rendered as expected.
Second, when attaching an image, removing it, and attaching a new
one, browsers were displaying the image preview of the first one. That's
because Paperclip generated the same URL from both files (as they both
had the same hash data and prefix). Browsers usually cache images and
render the cached image when getting the same URL.
Since now we're storing each image in a different Blob, the images have
different URLs and so the preview of the second one is correctly
displayed.
Finally, when users downloaded a document, they were getting files with
a very long hexadecimal hash as filename. Now they get the original
filename.
Some developers work on CONSUL installations where Spanish and/or
English aren't part of the available locales. In those cases, the
`dev_seed` task was crashing because we were using attributes like
`name_en` and `name_es`.
So we're using attributes for random locales instead.
We're using a proc so we don't have code like this all over the place:
random_locales.map do |locale|
I18n.with_locale(locale) do
phase.name = I18n.t("budgets.phase.#{phase.kind}")
phase.save!
end
end
This would make the code harder to read and would execute a `save!` once
per locale, which would make the task much slower.
We could also avoid the procs writing something like:
def random_locales_attributes(**attribute_names_with_values)
random_locales.each_with_object({}) do |locale, attributes|
I18n.with_locale(locale) do
attribute_names_with_values.each do |attribute_name, (i18n_key, i18n_args)|
value = I18n.t(i18n_key, (i18n_args || {}).merge(language: I18n.t("i18n.language.name")))
attributes["#{attribute_name}_#{locale.to_s.underscore}"] = value
end
end
end
end
And calling the method with with:
random_locales_attributes(name: ["seeds.budgets.name", year: Date.current.year - 1])
However, this code would also be different that what we usually do, we'd
have to apply some magic to pass the `language:` parameter, and the
strings wouldn't be recognized by i18n-tasks, so we aren't sure we're
really gaining anything.
We were very inconsistent regarding these rules.
Personally I prefer no empty lines around blocks, clases, etc... as
recommended by the Ruby style guide [1], and they're the default values
in rubocop, so those are the settings I'm applying.
The exception is the `private` access modifier, since we were leaving
empty lines around it most of the time. That's the default rubocop rule
as well. Personally I don't have a strong preference about this one.

Instead of using I18n for the field texts and forcing the
locale (e.g. `I18n.t('seeds...', locale: :es)`), I'm moving
content out of `config/locales/` and into the seed file.
This is because this content is less about reacting to different
locales (the locale would always be forced so we don't actually
use the main i18n functionality), and more about demonstrating
the "translatable fields" feature.
