Question

当我想用ActiveAdmin删除用户时，我收到以下错误：

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" = $1

我通过添加has_many :recherches, dependent: :destroy来修复此问题，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Recherche类有关，但我找不到问题的来源。是控制器吗？该模型？还有什么吗？

Answer 1

假设您的信息，由于此代码：

has_many :recherches, dependent: :destroy

... Rails试图将复数'recherches'变成一个单独的'recherch'，这不是你班级的名字 - 'Recherche'，正如你所说的那样。在这种情况下，您必须覆盖Rails的命名约定：

# config/initializers/inflections.rb

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

Admin :: Users＃index中的NameError
