Admin::Users#index 中的名称错误

NameError in Admin::Users#index

当我想使用 ActiveAdmin 删除用户时,出现以下错误:

PG::ForeignKeyViolation: ERROR: update or delete on table "users" violates foreign key constraint "fk_rails_18841639d7" on table "recherches" DETAIL: Key (id)=(5) is still referenced from table "recherches". : DELETE FROM "users" WHERE "users"."id" = 

我通过添加 has_many :recherches, dependent: :destroy 解决了这个问题,但现在我收到以下错误:

NameError in Admin::Users#index


Showing /home/charles/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/bundler/gems/activeadmin-0a5a15b88bff/app/views/active_admin/resource/index.html.arb where line #2 raised:

uninitialized constant User::Recherch

这两个错误都与 class Recherche 有关,但我找不到问题的根源。是控制器吗?该模型?还有什么吗?

根据您的信息假设,由于此代码:

has_many :recherches, dependent: :destroy

...Rails 试图将复数 'recherches' 变成单数 'recherch',这不是您的 class - 'Recherche',如你所说。在这种情况下,您必须覆盖 Rails' 命名约定:

# config/initializers/inflections.rb

ActiveSupport::Inflector.inflections do |inflect|
  inflect.irregular 'recherche', 'recherches'
end
