I have this structure of code and for some reason hash is overrinding hash

    audiencias = Documento::Audiencia.obter_audiencias_por_periodo(orgao_id, data_inicial, data_final)
audiencias.each do |audiencia|
  ano = audiencia.dth_audiencia.year
  mes = audiencia.dth_audiencia.month - 1
  dia = audiencia.dth_audiencia.day
  hora = audiencia.dth_audiencia.hour
  situacao = audiencia.pendente?

  calendario_hash['calendario_status'] = {} if calendario_hash['calendario_status'].nil?
  calendario_hash['calendario_status'][ano] = {} if calendario_hash['calendario_status'][ano].nil?
  calendario_hash['calendario_status'][ano][mes] = {} if calendario_hash['calendario_status'][ano][mes].nil?
  calendario_hash['calendario_status'][ano][mes][dia] = {"pendente"=> situacao} if calendario_hash['calendario_status'][ano][mes][dia].nil?
  calendario_hash['calendario_status'][ano][mes][dia][hora] = {} if calendario_hash['calendario_status'][ano][mes][dia][hora].nil?

  audiencia = JSON.parse(audiencia.to_json(:only => [:id, :desc_audiencia, :dth_audiencia, :finalizada, :nr_processo_judicial], :include => {:objeto_tramitacao => {:only => [:id, :nr_objeto_tramitacao, :referencia]}, :audiencia_tipo => {:only => [:id, :nm_audiencia_tipo]}}))
  situacao = Documento::Audiencia.find_by_id(audiencia['audiencia']['id']).pendente?
  audiencia['audiencia']['pendente'] = situacao
  calendario_hash['calendario_status'][ano][mes][dia][hora]['audiencias'] = []
  calendario_hash['calendario_status'][ano][mes][dia][hora]['audiencias'] << audiencia['audiencia']
end

I want to know if have some way to hash not override other hash in this structure [EDIT] Example: Day 28 could have different audiências in same hour

   2021=>{
    8=>{
        28=>{
            15=>[
                {
                    "id"=>56,
                     Audiência 
                },
                {
                    "id"=>59,
                      Audiência 
                }
            ]
        }
    }
}

}

CodePudding user response：

hash will obviously override if there is same key present in hash. You're using a loop to generate the hash. In the middle of the loop, the calendario_status key is same for all audiencia. Also, ano, mes, dia can be same for different audiencia. use uniq key. I would prefer to do it like this way:

audiencias.each do |audiencia|
  ano = audiencia.dth_audiencia.year
  mes = audiencia.dth_audiencia.month - 1
  dia = audiencia.dth_audiencia.day
  hora = audiencia.dth_audiencia.hour
  situacao = audiencia.pendente?

  calendario_hash['calendario_status'] ||= {}
  calendario_hash['calendario_status'][ano] ||= {}
  calendario_hash['calendario_status'][ano][mes] ||= {}
  calendario_hash['calendario_status'][ano][mes][dia] ||= {"pendente"=> situacao}
  calendario_hash['calendario_status'][ano][mes][dia][hora] ||= {}

  audiencia = JSON.parse(audiencia.to_json(:only => [:id, :desc_audiencia, :dth_audiencia, :finalizada, :nr_processo_judicial], :include => {:objeto_tramitacao => {:only => [:id, :nr_objeto_tramitacao, :referencia]}, :audiencia_tipo => {:only => [:id, :nm_audiencia_tipo]}}))
  situacao = Documento::Audiencia.find_by_id(audiencia['audiencia']['id']).pendente?
  audiencia['audiencia']['pendente'] = situacao
  calendario_hash['calendario_status'][ano][mes][dia][hora]['audiencias'] ||= []
  calendario_hash['calendario_status'][ano][mes][dia][hora]['audiencias'] << audiencia['audiencia']
end

This way, we've always a uniq key audiencia.id in the hash.

I know you're expecting to override some value as you mentioned in the comment { "calendario_status"=>{ 2021=>{ 8=>{ 10=>{ 16=> {}}. But think, if in the middle of the expecting hash, mes value is same for two audiencia, then the whole calendario_hash['calendario_status'][ano][mes] will be override, which is not expected, right?
