Herokuのは、sqlite3のをサポートしていないよう

マイdatabase.ymlのは、あなたのdatabase.ymlファイルで

# SQLite version 3.x 
# gem install sqlite3 
# 
# Ensure the SQLite 3 gem is defined in your Gemfile 
# gem 'sqlite3' 
# 
default: &default 
    adapter: sqlite3 
    pool: 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

は、PostgreSQLを使用するために、生産DBを変更します。

たとえば：あなたはdefualt値を含めているので、それはsqliteのように設定なっている。このコードでだから

production: 
    database: example_production 
    adapter: postgresql 
    host: localhost 
    password: 

Answer 2

あなたはこのコード

default: &default 
    adapter: sqlite3 
    pool: 5 
    timeout: 5000 

で、デフォルトのデータベースとしてのsqliteを設定しています、 herokuではsqliteを使用できないため、herokuでは動作しません。

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

database.ymlファイルの本番データベースの値を変更する必要があります。

production: 
    adapter: postgresql 
    pool: 5 
    timeout: 5000 
    database: app_name
