ruby-on-rails - Rails Graphql 解决错误 : wrong number of arguments (given 1, 预期 3)

Question

我使用 graphql 创建了新的 Rails 应用程序，但在 6 个月以上的指南中遇到了很多问题。我怀疑 graphql-ruby 变化得相当快。

所以我在 resolve 方法中的最后一个问题:

module Types
  class QueryType < Types::BaseObject
    graphql_name "Root Query"
    description "The query root of this schema"

    field :allProducts, [ProductType], null: false do
      resolve ->(_obj, _args, _ctx) { Product.all }
    end
  end
end

错误:

wrong number of arguments (given 1, expected 3)

我使用的是最新版本:

gem "graphql", "~> 1.9.0.pre1"

但是 1.8.* 出现同样的错误

好的，那个resolve 东西不再起作用了。下一个代码工作正常:

class QueryType < Types::BaseObject
  graphql_name "RootQuery"

  field :categories, [Types::CategoryType], null: false

  def categories
    Category.all
  end
end
