I get private method `open' called for Rack::File:Class when I rackup. Really can't see where the problem is. Running rack 1.1. Help please...
There is a Rack::File class, which has precedence in your rackup file because of the way Ruby looks up names. This is not the class you are looking for, you want Ruby's own File class. That class can be referenced directly without lookup ambiguity by using the prefix ::
::File.open('public/index.html')

I'm getting an error when attempting to change the :filename of my paperclip attachment to equal an attribute on the class I'm attaching the paperclip file to.
When I use "#{self.company_name}" it errors out. Apparently in this scope, "self" is not Company. When I wrote this line I assumed that self is the instance of Company that I'm uploading this attachment to. Any idea how I can fix this? The Paperclip docs say to use ":filename" but I'd like to use the value of Company.company_name instead.
class Company < ActiveRecord::Base
include AliasAttrs
has_attached_file :company_logo, {
:storage => :ftp,
:path => "/logos/#{self.company_name}",
:url => FTP_CONFIG[:access_host]+"logos/:filename",
:ftp_servers => [
{
:host => FTP_CONFIG[:host],
:user => FTP_CONFIG[:user],
:password => FTP_CONFIG[:pass],
:port => 21 # optional, 21 by default
}
]
}
end
Update
I tried using the advice found in this post: https://robots.thoughtbot.com/paperclip-tips-and-updates
But now I am getting the following error when starting my server:
undefined method `interpolations' for Paperclip::Attachment:Class (NoMethodError)
It looks like the syntax for interpolations has changed. Updated it and it worked. Add the following to your model or create a paperclip.rb file in config/initializers
Paperclip.interpolates :company_name do |attachment, style|
attachment.instance.company_name
end
I have a Middleman app which I am serving using Rack::TryStatic.
Here is the config.ru.
use Rack::TryStatic,
root: 'build',
urls: %w[/],
try: ['.html', 'index.html', '/index.html']
run lambda{ |env|
four_oh_four_page = File.expand_path("../build/404.html", __FILE__)
[ 404, { 'Content-Type' => 'text/html'}, [ File.read(four_oh_four_page) ]]
}
My understanding is that when you use a config.ru with run, map or use
methods, they are converted to a Rack::Builder object.
I've tried wrapping this config in a Rack::Builder object like this:
app = Rack::Builder.new do
use Rack::TryStatic,
root: 'build',
urls: %w[/],
try: ['.html', 'index.html', '/index.html']
run lambda{ |env|
four_oh_four_page = File.expand_path("../build/404.html", __FILE__)
[ 404, { 'Content-Type' => 'text/html'}, [ File.read(four_oh_four_page) ]]
}
end
run app
When I do this, I get the 404 page for all requests.
Why doesn't this work?
It looks like there is a bug in the current released version of TryStatic that has been fixed in master, where the try array is being lost when used in way that causes the middleware to be reinitialized.
You can avoid this by making sure the app only get s initialized once by using to_app:
run app.to_app
or equivalently use app instead of new:
app = Rack::Builder.app do
# ...
I currently have a static website that deploys to Heroku via a Rack app. Here is what my rack file looks like :
use Rack::Static,
:urls => ["/images", "/javascript", "/css", "/favicon.ico"],
:root => "public"
run lambda { |env|
[
200,
{
'Content-Type' => 'text/html',
'Cache-Control' => 'public, max-age=86400'
},
File.open('public/index.html', File::RDONLY)
]
}
I downloaded a config file from New Relic's site, but now I need to implement New Relic. Does anyone know what I need to change in my Rack file from the yml file?
You could try just including the the yml file in the root path of your project.
New Relic is not setup to handle static applications at this point.
I have followed the Heroku guide on deploying static files using Ruby Rack (https://devcenter.heroku.com/articles/static-sites-ruby),
However I am unable to access any HTML file in \public apart from index.html (every URL resolves to the home page)
The config.ru file :
use Rack::Static,
:urls => ["/bootstrap", "/css", "/fonts", "/images", "/js", "/font-awesome"],
:root => "public"
run lambda { |env|
[
200,
{
'Content-Type' => 'text/html',
'Cache-Control' => 'public, max-age=86400'
},
File.open('public/index.html', File::RDONLY)
]
}
I have checked the following posts :
Ruby Rack Heroku: Serving Static Files
How to setup URLs for static site with Ruby Rack on Heroku
Still I am unable to go beyond the index.html page.
While I change the config.ru as shown below ... I get application error
use Rack::Static,
:urls => ["/bootstrap", "/css", "/fonts", "/images", "/js", "/font-awesome"],
:root => "public"
map "/" do
run lambda { |env|
[
200,
{
'Content-Type' => 'text/html',
'Cache-Control' => 'public, max-age=86400'
},
File.open('public/index.html', File::RDONLY)
]
}
end
map "/about" do
run lambda { |env|
[
200,
{
'Content-Type' => 'text/html',
'Cache-Control' => 'public, max-age=86400'
},
File.open('public/about/index.html', File::RDONLY)
]
}
end
Is there a way to map multiple URLs? I have 5-6 pages in my index.html, but unable to access.
Thanks for your help.
You could create a simple controller that just renders these pages. May be easier than trying to bypass the MVC. Let me know if you need help with this :)
Update -----
Example
Controller:
class PublicController < ApplicationController
def index
render "public/index"
end
def about
render "public/about/index"
end
end
Then place your html files in the views folder in the sub-directories specified in the controller.
Also don't forget to add these methods to your routes.rb file in the config directory.
I'm using Middleman to create a static site.
Middleman generates static html files into ./build directory.
Here's the config I'm currently using:
require 'rubygems'
require 'middleman'
require 'rack/contrib/try_static'
use Rack::TryStatic, :root => "build", :urls => %w[/], :try => ['.html']
run Middleman::Application.server
So Middleman is serving the static files right now. How can I make Rack::TryStatic handle the requests directly?
I tried to make it something like
run Rack::TryStatic, :root => "build", :urls => %w[/], :try => ['.html']
But it doesn't work is run only accepts 1 argument. And Rack::TryStatic requires 2 arguments, app and options to initialize, and I don't have any app.
How can I do this?
(And if it matters, I'm deploying to Heroku)
As you’ve noticed, a Rack middleware component such as Rack::TryStatic needs another app to pass requests onto. You could create a simple one to use that for example just returned a 404 response, such as:
app = lambda {|env| [404, {'Content-type' => 'text/plain'}, ['Not found']
run Rack::TryStatic.new app, :root => "build", :urls => %w[/], :try => ['.html']
or equivalently:
use Rack::TryStatic, :root => "build", :urls => %w[/], :try => ['.html']
run lambda {|env| [404, {'Content-type' => 'text/plain'}, ['Not found']]}
If you have your own 404 file, you could use rack-contrib’s Rack::NotFound instead of a custom end point of your own:
use Rack::TryStatic, :root => "build", :urls => %w[/], :try => ['.html']
run Rack::NotFound.new('path/to/your/404.html')
If you weren’t using the :try array of file extensions to try and serve, you could use Rack::File directly. Internally, Rack::TryStatic uses Rack::Static, which in turn uses Rack::File. Unlike TryStatic and Static, Rack::File is a Rack application in its own right, and so doesn’t need a separate app to pass requests to. Your config.ru would then simply be:
run Rack::File.new './build'
although this wouldn’t allow for “bare” requests to be served with the corresponding .html file — all requests would need to specify the whole file name.
