Question

我有this架构。它似乎是多对多的，但它是由EclipseLink生成的，带有这些模型

    public class LancamentoContabil implements Serializable {
     // objects 
    }

    public class MovimentacaoContabil implements Serializable, CheckPeriodo {
     @OneToMany(cascade={CascadeType.ALL}, orphanRemoval=true)
     @OrderBy("tipo DESC")
     private List<LancamentoContabil> lancamentos = newArrayList();
   }

我将这些类映射到Rails项目中使用：

class LancamentoContabil < ActiveRecord::Base
  self.table_name = 'lancamentocontabil'

  belongs_to :conta, class_name: 'PlanoConta'
  belongs_to :empresa
end

class MovimentacaoContabil < ActiveRecord::Base
  self.table_name = 'movimentacaocontabil'

  belongs_to :empresa

  has_and_belongs_to_many :lancamentos, foreign_key: 'movimentacaocontabil_id', 
                          class_name: 'LancamentoContabil', association_foreign_key: 'lancamentos_id',
                          join_table: 'movimentacaocontabil_lancamentocontabil'

end

当activerecord尝试保存MovimentacaoContabil时，我收到此错误：

ActiveRecord::StatementInvalid Exception: PG::NotNullViolation: ERROR: null value in column "movimentacaocontabil_id" violates not-null constraint 可以找到完整的sql here

我不知道这里发生了什么......欢迎任何想法

activerecord无法保存在关联表上
