我正在尝试创建一个查询，以从“报价”表返回经过过滤的报价清单。
该代码位于引擎名称“ cpq”内
types / quotation_type.rb
module Cpq
module Types
class QuotationType < ::Cpq::Types::BaseObject
field :id, ID, null: false
field :inc_id, Integer, null: false
field :name, String, null: false
field :description, String, null: true
field :buyer_id, ID, null: true
field :seller_address, String, null: true
field :buyer_address, String, null: true
field :quotation_no, String, null: false
field :updated_at, ::Types::DateTimeType, null: false
end
class QuotationReturnType < ::Cpq::Types::BaseObject
field :success, Boolean, null: false
field :quotation_data, [::Cpq::Types::QuotationType], null: true
field :page, Integer, null: true
field :total, Integer, null: true
field :total_count, Integer, null: true
end
end
end
types / query_type.rb
Cpq::Types::QueryType = GraphQL::ObjectType.define do
name "Query"
field :quotations do
type ::Cpq::Types::QuotationReturnType
argument :id, types.ID
argument :name, types.String
argument :buyer_ids, types[types.ID]
argument :statuses, types[types.String]
argument :page, types.String
argument :page_limit, types.String
argument :sort_by, types.String
...
...
resolve -> (obj, args, ctx) {
quotation_ids = []
quotation_ids << args[:id] if args[:id].present?
name = args[:name]
...
...
return {
success: true,
page: page,
total: total,
total_count: total_count,
data: quotation.as_json(::Cpq::Quotation.as_json_query)
}
}
end
end
但是，在查询“报价”时，出现错误

当我在控制台上尝试时，我意识到，一旦我以前访问过Cpq :: Types :: QuotationType类型，便可以访问QuotationReturnType类。但是，如果我只是尝试访问Cpq :: Types :: QuotationReturnType，则会给我一个错误。可能无法加载它或其他东西。 困惑。请帮忙。 附言我是graphql的新手，因此，如果提到的话，请忽略任何幼稚/多余的代码。
