If you don't know what that means, your application probably isn't thread-safe. This might cause unexpected behavior if your application or dependencies are not thread-safe. Note that this allows concurrent requests served from the same process using threads. In config/environments/development.rb set config.allow_concurrency = true (default in Rails 4).If you don't want to use Passenger you can also do this: However, Passenger does not allow to use debugger or byebug. The easiest fix for this is to use Passenger Standalone for development, which can spawn multiple worker processes. When using a singlethreaded development server like Thin there is no additional worker process available to deliver those assets.

RAILS PDFKIT HOW TO
There are concepts and formattings that only make sense on paper, so the question is how to implement them if you only have CSS: How to express page breaks, headers, footers, etc. However, you should always have quiet: true to keep your test output and logs clean. You can get a list of supported options by running man wkhtmltopdf. Most options are forwarded to wkhtmltopdf (see below). # disable_smart_shrinking: true, # Enable to keep the pixel/dpi ratio linearĬonfig.wkhtmltopdf = ('vendor/wkhtmltopdf/linux-trusty-amd64/wkhtmltopdf').to_s No_outline: true, # Disable the default outline Load_media_error_handling: 'abort', # Crash early Load_error_handling: 'abort', # Crash early Quiet: true, # No output during PDF generation
