Đường ray không thể khởi động khi serve_static_assets bị vô hiệu hóa trong sản xuất

Question

Trang web hoạt động tốt cho đến khi tôi thêm config.serve_static_assets = false vào sản xuất của mình.rb. Sau đó, tôi chỉ có được điều này:

demosite.com(master)$ RAILS_ENV=production rails s 
WARNING: Use strings for Figaro configuration. false was converted to "false".

Cụ thể trong development.rb của tôi, tôi có các thiết lập liên quan đến tài sản:

# Disable Rails's static asset server (Apache or nginx will already do this). 
config.serve_static_assets = false 

# Do not fallback to assets pipeline if a precompiled asset is missed. 
config.assets.compile = false 

# Generate digests for assets URLs. 
config.assets.digest = false 

Bất kỳ trợ giúp sẽ được đánh giá cao.

Answer 1

Vấn đề là dòng này trong engine.rb của tôi (Tôi đang chạy một công cụ đường ray trong đá quý tùy chỉnh).

app.middleware.insert_before(::ActionDispatch::Static, ::ActionDispatch::Static, "#{root}/public") 

Tôi bọc đường với điều này câu lệnh if và bây giờ tất cả mọi thứ đang làm việc:

if Rails.application.config.serve_static_assets 
    app.middleware.insert_before(::ActionDispatch::Static, ::ActionDispatch::Static, "#{root}/public") 
end
