Пользователь сохраняет текст в форме со словом «café» (обратите внимание на «é»). При загрузке страницы #show, отображающей этот текст, я получаю сообщение Encoding::CompatibilityError с сообщением incompatible character encodings: UTF-8 and ASCII-8BIT.Получение «несовместимых кодировок символов: UTF-8 и ASCII-8BIT» при отображении введенного пользователем символа ASCII-8BIT
Ошибка может дублироваться в консоли:
> r = Report.find(123) # load the record
> r.update(:comments => "café")
=> true
> r.comments
=> "caf\xC3\xA9"
> r.comments.encoding
=> #<Encoding:ASCII-8BIT>
> r.comments.encode("UTF-8")
Encoding::UndefinedConversionError: "\xC3" from ASCII-8BIT to UTF-8
from (irb):11:in `encode'
Отображение поля на странице #show (<%= r.comments %>) производит ошибку.
Что кодировка не UTF-8, но ASCII-8BIT, кажется неправильной, поскольку кодировка столбца базы данных установлена в UTF-8, а множество конфигураций приложений определяют кодировку как «UTF-8».
В идеале, «é» отображается так, как он был введен без каких-либо ошибок, но на данный момент я бы согласился только на то, чтобы избежать ошибки. Кажется, все мои формы (десятки) восприимчивы к этому.
Есть ли способ отображать символы ASCII-8BIT?
Принудительное кодирования (<%= string.force_encoding("UTF-8") %>) дает желаемый результат, избегая ошибку и отображаются символы, которые привели к следующему обходному пути:
Временного решения
# /config/initializers/active_record_extension_force_encode_read_attribute.rb
module ActiveRecordExtensionForceEncodeReadAttribute
def read_attribute(attr_name)
attribute = super
attribute.is_a?(String) ? attribute.force_encoding("UTF-8") : attribute
end
end
# include the extension
ActiveRecord::Base.send(:include, ActiveRecordExtensionForceEncodeReadAttribute)
Это чувствует себя неправильно по нескольким причинам, но работает.
Моя установка
Я использую mysql2 камень. Столбцами базы данных являются все типы данных UTF-8, TEXT. Я следил за предложениями, чтобы объявить кодировку UTF-8 для моего приложения (через How to fix ActionView::Template::Error (incompatible character encodings: ASCII-8BIT and UTF-8)).
Параметры выглядеть следующим образом
Parameters: {"utf8"=>"✓", "authenticity_token"=>"my_auth_token=", "commit"=>"Save", "report"=>{"comments"=>"café "}}
Ошибка Encoding::CompatibilityError in WeekendManagerReports#show (вид) с сообщением: incompatible character encodings: UTF-8 and ASCII-8BIT и получает отмечается в представлении, где я печатаю атрибут:
<%= @report.comments %>
