Ruby版本:2.0.0p195 Rails:4.2.0beta4
所以我尝试运行rake资产:预编译。 (听起来像一个好主意)我得到以下痕迹:

我正在学习Ruby on Rails,所以请假设我错过了明显的东西。
编辑:
你是对的trueinViso - 我没有在database.yml中指定postgres。我该怎么写?这是database.yml:
# 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
答案 0 :(得分:0)
我做了什么: 我改变了开发数据库以使用postgres'pg'gem。 (这可能没用。我实际上不知道它是否相关)。
最重要的是,在完成上述操作后,我将database.yml更改为(适配器错误“postgresl”:
development:
adapter: postgresql
host: localhost
database: pqqq
username: pqqqq
password: pqqqq
test:
adapter: postgresql
encoding: unicode
database: testdb_pow
pool: 5
username: parseb
password: testtt
比我运行rake asstes:预编译,然后git push heroku master,它工作正常。 (不要忘记在heroku上迁移数据库 - heroku run db:migrate。)
答案 1 :(得分:-1)
您不需要运行rake assets:precompile
。
只需转到config/production.rb
并设置serve_static_assets = true
。
# Disable Rails's static asset server (Apache or nginx will already do this).
config.serve_static_assets = true
当您再次推送到heroku时,资产将起作用。 那是我的解决方案。
