먼저 Ruby에 대한 지식 부족과이 게시물 전체에서 특정 용어를 오용 할 가능성이 높습니다. 나는 이것에 극단적으로 새로운이고 나는 간신히 모든 것의 걸림 새를 얻고있다.

이 문제의 원인이 될 수있는 어떤 생각의 무리를 얻으려면? 이것은 무엇을 내 database.ysml 파일의 모습입니다 :

편집

이

source 'https://rubygems.org' 

git_source(:github) do |repo_name| 
    repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/") 
    "https://github.com/#{repo_name}.git" 
end 

ruby '2.3.4' 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '~> 5.1.4' 
# Use sqlite3 as the database for Active Record 
group :development, :test do 
    gem 'sqlite3' 
end 

group :production do 
    gem 'pg' 
end 

('sqlite3를'입니다 어디에 코드의 단지 부분을 보여주기 위해) :

이 내 Gemfile 파일의 모습입니다 like :

# SQLite version 3.x 
# gem install sqlite3 
# 
# Ensure the SQLite 3 gem is defined in your Gemfile 
# gem 'sqlite3' 
# 
default: &default 
    adapter: sqlite3 
    pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %> 
    timeout: 5000 

development: 
    <<: *default 
    database: db/development.sqlite3 

# Warning: The database defined as "test" will be erased and 
# re-generated from your development database when you run "rake". 
# Do not set this db to the same as development or production. 
test: 
    <<: *default 
    database: db/test.sqlite3 

production: 
    <<: *default 
    database: db/production.sqlite3 

Answer 1

데이터베이스 및 어댑터를 config/database.yml에 잘못 설정했습니다. 여기

: 당신은 당신의 기본 데이터베이스 어댑터가 sqlite3를 것을 지정하는

default: &default 
    adapter: sqlite3 
    pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %> 
    timeout: 5000 

. 그런 다음 제작 과정에서 다음을 수행합니다.

production: 
    <<: *default 
    database: db/production.sqlite3 

adapter: 값을 절대로 지정하지 마십시오. 즉 default에 설정 한 값인 sqlite3을 사용하고 있음을 의미합니다.

또한 프로덕션 환경에서 사용할 데이터베이스가 당연히 정확하지 않은 db/production.sqlite3임을 지정하고 있습니다. 그것이 말하는 방법, adapter: postgresql를 참조

production: 
    <<: *default 
    adapter: postgresql 
    database: contacts_production 
    username: contacts 
    password: <%= ENV['CONTACTS_DATABASE_PASSWORD'] %> 

:

생산 설정은 더 좋아 보일 것이다? 그러면 기본값보다 우선 적용됩니다. 따라서 생산 (Heroku)에서는 대신 postgresql을 사용하도록 구성됩니다.

물론 database:, username: 및 password: (방금 프로젝트 중 하나에서 가져온 것)이 필요합니다. 이것은 정확하게 정확하지 않을 수도 있습니다. 따라서 조금이라도 소란스럽게해야 할 것입니다.

또한 옵션이있는 경우 모든 환경에 대해 postgresql을 사용해야합니다. 데이터베이스는 미묘한 차이점이 있으며, 서로 다른 환경에서 서로 다른 데이터베이스를 사용하여 마음이 편한 것입니다.
