Im using middleman to render index.html.erb (int), index.us.html.erb (us), index.br.html.erb (br) to load localized content.
It works fine with all locales except for BR.
I have created locales/br.yml
---
br:
hello: "Hello"
Also, my config.rb file has proper i18n activation.
# Country specific pages ('source/html')
activate :i18n,
:mount_at_root => :int,
:templates_dir => "html",
:langs => [:int, :in, :us, :br]
When I visit http://localhost:4567/br it load int template for br
Also, please note if Im using the build source, it works perfectly fine. But I in development environment while running server with bundle exec middleman BR doesn't load correct template.
Please let me know if you need any more code from my side.

I have a normal Rails layout which is my normal Site.
I want a Button on this page to convert/transform this page into
a PDF file.
I want to do it with this gem:
https://github.com/mileszs/wicked_pdf
I added gem 'wicked_pdf' to my Gemfile, but now how can I convert the actual page?
Here's what I did to use wicked_pdf:
# Gemfile
gem 'wicked_pdf'
gem 'wkhtmltopdf-binary' # if you need the binary too
Then run
$ bundle install
$ (bundle exec) rails g wicked_pdf # generates the initializer
Then you can configure global settings in config/initializers/wicked_pdf.rb as stated in the wicked readme on github.
Rails 4 already knows the pdf mime type, but in older versions you'll probably need to register pdf as a mime type:
# config/initializers/mime_types.rb
Mime::Type.register "application/pdf", :pdf
In your controller
respond_to do |format|
format.html
format.pdf do
render pdf: "your-filename"
end
end
Then you put a view under app/views/<your-view>/<controller-action>.pdf.erb with the content you wan't.
To reference this by a link you can do something like:
= link_to "Get PDF", your_path(format: :pdf)
Does this solve your question?
Please follow the below link. Its a details tutorial, this will make your life easier:
http://dchua.com/2014/10/30/generate-pdfs-with-html-templates-in-rails/
Note
If you don't want to have your pdf views separately and want to use the same html view, then please use
template: invoices/show.html.erb
instead of
template: invoices/show.pdf.erb
I'm trying to make my sinatra app show a custom error page when an error is raised on the server (e.g. an IOError or ArgumentError).
Currently I'm using AJAX to load the results into a certain #results div, but if and when an error arises on the server, I would like an error page to open up on a new page.
Currently, the IOError is shown on the server and a error is seen in the console (the server responded with a status of 500 (Internal Server Error)). Other than that, nothing happens.
I think that I have to play about with the Javascript (as well as the Sinatra::Base class) but I've spent the whole of yesterday and this morning not getting anywhere.
I would be very grateful for any help. I've created an oversimplified version of my app which I have shown below...
Sinatra_app.rb
require 'sinatra/base'
require9 'sinatra'
require 'slim'
# A helper module
module GVhelpers
def create_results(name)
# raise IOError, "There's a problem..."
return "<p>The Server Says 'Hey #{name}'</p>"
end
end
class GVapp < Sinatra::Base
helpers GVhelpers
set :root, File.dirname(__FILE__)
error do
#error = env['sinatra.error']
slim :"500", :locals => {:error => error}
end
get '/' do
slim :index
end
post '/form' do
name = params[:personName]
create_results(name)
end
end
GVapp.run!
index.slim (in views folder)
script src="/jquery.min.js"
script src="/Gvapp.js"
form#sayHey action="/form" method="post"
| Name:
input type="text" name="personName"
br
input type="submit"
#output
500.slim (in views folder)
h1 Oops! Something went Wonky!
p Apologies, there was an error with your request:
strong request.env['sinatra.error'].message
p If the error persists, please contact the administrator.
Gvapp.js (in public folder)
$(document).ready(function() {
$('#sayHey').submit(function(e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: '/form',
data: $('#sayHey').serialize(),
success: function(response){
$('#output').html(response);
}
})
})
})
Sinatra swallows exceptions when run in the development environment by default and shows its debugging error page instead. So, to trigger your custom error handlers, you have to either run the application inside a Rack environment other than development (probably production), or preferably, tell Sinatra to not use its default error handlers in development mode.
Consider the following, standalone Sinatra application example:
require "sinatra"
#disable :show_exceptions
get "/" do
raise RuntimeError.new("boom")
end
error RuntimeError do
"A RuntimeError occured"
end
If you run this application using the default development environment like this:
$ ruby foo.rb
Then you will get Sinatra’s default error page. If you uncomment the disable line in the example, the error handler will be triggered instead, displaying a page containing "A RuntimeError occured". Alternatively, you can, as explained, run the application in an environment other than development as only that one pre-sets the show_exception setting. You can do that by setting the RACK_ENV environment variable:
$ RACK_ENV=production ruby foo.rb
For development purposes, setting RACK_ENV to production is not the correct way of course. Use disable :show_exceptions instead. You can use a configure block as outlined in the Sinatra README to conditionally disable the setting for the development environment.
configure :development do
disable :show_exceptions
end
That behaviour is documented in Sinatra’s documentation on configuration, along with several other useful settings.
I am working in rails 4 and I am trying to authenticate using github. So in my Github application I have this:
URL: http:// localhost:4000
Callback URL: http:// localhost:4000/auth/github/callback
The callback url is the url that Github will try to reach when the authentication is done right?
So why do I get a Github page 404 error when I click on my link:
<%= link_to 'Sign in with Github', '/auth/github' %>
I am working on a localhost development enviroment so that might be the problem?
Also when i type http:// localhost:4000/auth/github/callback on my browser I get an OmniAuth::Strategies::OAuth2::CallbackError
why? I have this in my routes.rb
post 'auth/:provider/callback' => 'home#index'
Is Rails 4 and Omniauth bugged?
(added the space in localhost so stackoverflow accepts my post)
I have github working with the gem omniauth-github
and a file config/initializers/omniauth.rb containing
Rails.application.config.middleware.use OmniAuth::Builder do
provider :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET']
end
However, when I enter http://localhost:3000/auth/github/callback on my browser I also get OmniAuth::Strategies::OAuth2::CallbackError so this shouldn't be the problem.
My config/environment.rb looks like
# Load the rails application
require File.expand_path('../application', __FILE__)
# Load the app's custom environment variables here, so that they are loaded before environments/*.rb
app_environment_variables = File.join(Rails.root, 'config', 'app_environment_variables.rb')
load(app_environment_variables) if File.exists?(app_environment_variables)
...
and my config/app/environment_variables.rb looks like
# OAuth Keys and Secrets
if Rails.env.production?
ENV['GITHUB_KEY'] = 'd1234a3a123a1a3a123c'
ENV['GITHUB_SECRET'] = '1234azer123azer1231209jeunsghezkndaz1234'
else
ENV['GITHUB_KEY'] = 'qsflkjkj685bg554456b'
ENV['GITHUB_SECRET'] = 'qslkfj7757kqfmlsdh675hlfsd587kjfdh687jsd'
end
See Is it possible to set ENV variables for rails development environment in my code? for more details on that.
I have 2 applications registered on github. One app_name-dev with key qsflk..., url http://localhost:3000 and callback url http://localhost:3000/auth/github/callback and one app_name with key d1234a....
Check that you have done that correctly. Maybe try to change localhost to 127.0.0.1.
For me it was Github's new stricter URI matching that was producing a 404 when trying to redirect to http://localhost:3000/auth/github/callback, I solved it by passing the redirect URI as a parameter with Omniauth.
Rails.application.config.middleware.use OmniAuth::Builder do
provider :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET'],
:scope => 'user,public_repo',
:redirect_uri => ENV['GITHUB_REDIRECT']
end
If your on Linux/Mac you can add environment variables from the command line.
$ export GITHUB_REDIRECT=http://localhost:3000/auth/github/callback
Alternatively, you could use something like Foreman that will let you add a .env file which you can use to store your variables in.
Just remember to add the appropriate redirect URI to your production environment's variables, and you're good, to go.
Working on rails, images are not visible and giving error.
Started GET "/assets/home.png" for 127.0.0.1 at 2012-06-19 12:23:24 +0530
Served asset /home.png - 404 Not Found (24ms)
ActionController::RoutingError (No route matches [GET] "/assets/home.png"):
I have used command
rake assets:precompile
production.rb
config.assets.compress = true
config.assets.compile = false
application.rb
config.assets.enabled = true
config.assets.version = '1.0'
Thanks for any help!
Actually you cannot reference your image with /assets/home.png path.
It will work in development mode, but in production all of your assets have a fingerprint in their filename (read this http://guides.rubyonrails.org/asset_pipeline.html#what-is-fingerprinting-and-why-should-i-care-questionmark)
That's why, in assets-pipeline enabled applications you need to reference all of your assets using helper methods. Read this doc to learn about the different helpers available in Ruby, JS and Sass files: http://guides.rubyonrails.org/asset_pipeline.html#coding-links-to-assets
The lack of a fingerprint in the file request suggests that you are running this in development. I am also going to guess that this is an app upgraded from an older version of Rails.
Any images need to be in the folder /assets/images for the pipeline to work.
Also, you do not need to precompile when in development mode.
Delete the public/assets folder, delete the folder tmp/cache/assets, and restart your server.
If this images are in the correct location, it should work.
I am newbe here about Netzke..
I am trying to follow the installation process in the Netzke web
site http://www.netzke.org and also from the git Netzke-core site..
I just download the EXT JS 4.0.2 zip file from Sencha, extract it and try to symbolic link the ext JS code to <railsdir>public/extjs directory..
and with the rails 3.1, I try also to link it to <railsdir>/app/assets/
javascripts and also <railsdir>/app/assets/stylesheets..
But it still does not work, because it doesn't find the file /extjs/resources/css/ext-all.css..
Please can you help which path or directory to link the EXT JS code to?
Linking the /code/sencha/EXT-4.0.2a to public/extjs
, that what I have done, but no success..
set config.assets.debug = false in environment/development.rb file
it will work with Netzke
I'm just newbie for Netzke too. I think your problem with model_name method is that you Use GridPanel without a config model to it. You should do something like this:
<% netzke :some_component, :class_name => "Netzke::Basepack::GridPanel", :model => "YourModel" %>
It should work :)
