밤새 PostgreSQL 설치 실패... Claude가 20분 만에 Rails 시스템 완성시킨 비결

PostgreSQL을 로컬에 설치하려고 하는데 계속 실패합니다.
권한 문제와 설정 오류가 반복됩니다.

다른 대안이 있을까요?

명리학 데이터를 Rails로 관리하고 싶습니다.

데이터 구조:
- Profile (기본 정보): 310건
- Wonkuk (원국, 사주): Profile당 1개
- Daeun (대운): Profile당 평균 5-8개
- Sewun (세운): Profile당 연도별 10개

JSON 데이터를 Rails 모델로 정규화하는 방법을 알려주세요.

data_310.json 파일을 Rails DB에 import하고 싶습니다.

JSON 구조:
{
  "tables": {
    "profiles": [...],
    "wonkuk": [...],
    "daeun": [...],
    "sewun": [...]
  }
}

UUID로 연결된 관계를 Rails ID로 변환하는 방법을 포함해서
Rake task를 만들어주세요.

Rails로 데이터베이스 만들어줘

명리학 데이터를 Rails로 관리하고 싶습니다. 

[JSON 구조 첨부] 

이 데이터를 정규화된 5개 테이블로 설계해주세요. 
Profile이 중심이고, Wonkuk은 1:1, Daeun은 1:N 관계입니다.

# UUID → record_number 매핑 테이블 생성
profile_uuid_map = {}
json_data['tables']['profiles'].each do |p|
  profile_uuid_map[p['profile_id']] = p['record_number']
end

# 사용할 때
record_number = profile_uuid_map[uuid]
profile = Profile.find_by(name: record_number)

begin
  Profile.create!(data)
  success += 1
rescue => e
  puts "Failed: #{data['name']} - #{e.message}"
  failed += 1
end

print "." if (index + 1) % 50 == 0
