Question

我收到此错误，但仅限于生产，并且仅在编辑特定记录时。它不会在开发中发生，也不会发生在任何其他记录中。不仅如此，模板中没有UTF字符，en.yml中没有UTF字符，记录也没有UTF字符！我可以查看/显示记录正常。

HAML

      .input-group
        - us = Country.find_by code: 'US'
        =cf.collection_select :country_id, [us] + Country.all, :id, :name, {prompt: t('company.country')}, class: 'form-control'
        .input-group-addon.required *

除了'Saint-Barthélemy'和'SãoTomé和Príncipe'之外，各国没有任何UTF字符。但是，我仍然可以编辑其他记录并列出所有国家/地区。

我在

中尝试了解决方案

ActionView::Template::Error (incompatible character encodings: UTF-8 and ASCII-8BIT)（我没有使用request。）
incompatible character encodings: ASCII-8BIT and UTF-8（模板中没有UTF。）
Error: Incompatible character encodings: UTF-8 and ASCII-8BIT（我设置NLS_LANG = AMERICAN_AMERICA.UTF8。）

他们都没有奏效。我也试过

  class Application < Rails::Application
    config.encoding = "utf-8"

我正在使用Heroku，Postgres，HAML和Rails 5.0.6。

Answer 1

我将本地服务器连接到生产数据库并尝试编辑记录。我用-#注释掉整个部分，直到它加载并缩小到.description字段，这肯定不是错误消息中的内容。我使用Web调试器打印出字段

>>  @user.company.description
=> "... world\xE2\x80\x99s largest ..."
>>  @user.company.description.encoding
=> #<Encoding:ASCII-8BIT>

我看到它不是UTF-8编码。（但奇怪的是它会在#show中显示它。我将问题跟踪到自定义类型

class Company < ApplicationRecord
  @@encrypted_fields = [:name, :phone, :address1, :address2, :ein, :bank, :url, :description]
  @@encrypted_fields.each do |ef|
    attribute ef, :encrypted

class EncryptedType < ActiveRecord::Type::Text
  # called when loading from DB
  def deserialize(value)
    value.decrypt.force_encoding('utf-8') unless value.nil?

我在解密后添加.force_encoding('utf-8')，现在可以正常使用。

没有UTF字符的HAML模板错误：ActionView :: Template :: Error（不兼容的字符编码：ASCII-8BIT和UTF-8）
