How to render a ruby file (which in my case returns a pdf document) for example:
get "/pdf" do
#locals = {some_locals_hash}
headers({'Content-Type' => 'application/pdf',
'Content-Description' => 'File Transfer',
'Content-Transfer-Encoding' => 'binary',
'Content-Disposition' => "attachment;filename=\"test.pdf\"",
'Expires' => '0',
'Pragma' => 'public'})
ruby :test, :layout => false, :locals => #locals
end
I know Tilt does not have ruby template. For now I put all content in a *.haml file like:
-# PDF file description
:ruby
pdf = Prawn::Document.new(
... docs settings)
... docs content
end
= pdf.render()
and I render it with haml :template ...etc...
Truth is, I only need this for syntax highlighting, my editor does not properly highlight embedded ruby code in haml files :(. So if it's to complicated don't bother...
I managed with a Tilt template
module Tilt
class RubyTemplate < Template
def prepare
end
def evaluate(scope, locals, &block)
super(scope, locals, &block)
end
def precompiled_template(locals)
data.to_str
end
end
register 'rb', RubyTemplate
end
and with a helper method
helpers do
def ruby(*args)
render(:rb, *args)
end
end
I't sure this is the best way, but at least is working :)

I am newbie in ruby and working on making performance automation framework using using 'ruby-jmeter' gem (provided by flood.io)
I have made following files structure
Where payload.rb and request.rb contains my common utility methods . Which I am calling from test.rb
(test.rb would be going to be written by QA ppl)
Performance Automation Framework Structure
request.rb (lying under 'common' folder)
require 'ruby-jmeter' #(Consider any 3rd party gem )
require 'rubygems'

'Accept-Encoding' => 'gzip, deflate'
}
return commonHeaderHashMap
end
end
end

I have a directory of existing files which I need to migrate into my rails app as part of a legacy migration. Essentially I need to upload these files manually and save a new record for them in the database. I haven't quite found the proper way to do this. Currently I have the following in a rake task:
#attachments.each do |attachment|
begin
new_attachment = Attachment.new
#attachment_file_path = "/home/username/Attachments/" + attachment.Filename
file = File.open(#attachment_file_path)
new_attachment[:file] = new_attachment.file.store!(file)
# Map old record fields to new
new_attachment.attributes = {
:project_id => attachment.ProjectID,
:name => attachment.Description,
:user_id => attachment.UserId,
:created_at => attachment.CreatedDate,
:updated_at => attachment.LastModifiedDate
}
new_attachment.save!
puts "Attachment added successfully "
rescue => error
puts "Error migrating Attachment: #{error}"
end
end
attachment.rb
class Attachment < ActiveRecord::Base
mount_uploader :file, FileUploader
end
uploader:
class FileUploader < CarrierWave::Uploader::Base
include CarrierWave::RMagick
include CarrierWave::MimeTypes
process :set_content_type
storage :fog
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
def extension_white_list
%w(jpg jpeg gif png pdf doc docx txt)
end
version :thumb do
process resize_to_fit: [152, nil]
end
def default_url
ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
end
protected
def image?(new_file)
if new_file.content_type == nil
return false
else
new_file.content_type.include? 'image'
end
end
end
This does not work currently. The file never gets uploaded, and occasionally I get the following error:
Failed to manipulate with rmagick, maybe it is not an image? Original Error: no decode delegate for this image format
In this instance, the file is a '.doc' file.
What is the correct way to open a local file and upload it manually via Carrierwave?
Any help is appreciated.
Try this
#attachments.each do |attachment|
begin
options = {
:project_id => attachment.ProjectID,
:name => attachment.Description,
:user_id => attachment.UserId,
:created_at => attachment.CreatedDate,
:updated_at => attachment.LastModifiedDate,
:file => File.new(File.join("/home/username/Attachments/",attachment.Filename))
}
new_attachment = Attachment.new(options)
new_attachment.save!
puts "Attachment added successfully "
rescue => error
puts "Error migrating Attachment: #{error}"
end
end
Perhaps that would do for you as carrierwave would internally call store! for you
Question?
Failed to manipulate with rmagick, maybe it is not an image? Original Error: no decode delegate for this image format
Not sure what are you trying to over here because you have define an image? method which is not specified in condition also is that something that you want the content_type to be only present for image file
if no perhaps only the process call would work
process :set_content_type
if yes then perhaps you have to do something like this
process :set_content_type , :if => :image?
def image?(new_file)
%w(jpg jpeg gif).include?(new_file.extension)
end
Hope this help
EDIT based upon the comment
try this just used the condition same logic
version :thumb ,:if => image? do
// your code
end
When i am running shoes.rb file, which contains code to install gem, it throws error.
Undefined method setup for Shoes:Class
Code:
Shoes.setup do
gem 'activerecord' # install AR if not found
require 'active_record'
require 'fileutils'
ActiveRecord::Base.establish_connection(
:adapter => 'postgresql',
:dbfile => 'shoes_app'
)
# create the db if not found
unless File.exist?("shoes_app.sqlite3")
ActiveRecord::Schema.define do
create_table :notes do |t|
t.column :message, :string
end
end
end
end
class ShoesApp < Shoes
require 'note'
url '/', :index
def index
para 'Say something...'
flow do
#note = edit_line
button 'OK' do
Note.new(:message => #note.text).save
#note.text = ''
#result.replace get_notes
end
end
#result = para get_notes
end
def get_notes
messages = []
notes = Note.find(:all, :select => 'message')
notes.each do |foo|
messages << foo.message
end
out = messages.join("n")
end
end
Shoes.app :title => 'Notes', :width => 260, :height => 350
The problem was using Shoes4, where the setup method was unimplemented.
Shoes4 now implements Shoes.setup for backwards compatibility reasons but you don't really need it, so it doesn't do anything except for printing a warning that you should rather do gem install gem_name instead of using Shoes.setup.
I'd like to be able to create template functions in Sinatra HAML templates that themselves contain haml. Is there any way to do this or something similar? It'd be cool if it could work with markdown too.
foo.haml
def foo(x)
%h2 something
%p something about #{x}
%h1 Herp de derp
= foo("mary")
= foo("us")
Cheers!
Actually, you can do something like this:
# app.rb
require 'sinatra'
require 'haml'
helpers do
def foo(name)
haml = <<-HAML
#hello_block
Hello, #{name}
HAML
engine = Haml::Engine.new(haml)
engine.render
end
end
get '/' do
haml :index
end
# index.haml
= foo 'World'
Function is close, what you really need is what's known as a partial. These are predefined templates that you can place inside other views. For instance, you may have a comment partial to display a comment's author, timestamp, content, etc. You can then render this partial for each of the comments on a particular post.
Essentially, you'll end up with the following
# _foo.haml.erb
%h2 somthing
%p= x
# index.haml.erb
%h1 Herp de derp
= render :partial => "foo", :locals => { :x => "mary" }
= render :partial => "foo", :locals => { :x => "us" }
I have come across a issue when writing some sinatra code I have the follow block of code
begin
# do stuff here
rescue SomeException::Class => ex
flash.now[:err] = "some error " + ex.message
ensure
erb :content, :layout => :mainlayout
end
The problem I have is the erb output is only partially rendered, mainlayout.erb is rendered, however, content.erb doesn't get included. I have used the same erb line in other parts of the application and they work fine.
The following actually works and is a work around that I am currently using
begin
# do stuff here
erb :content, :layout => :mainlayout
rescue SomeException::Class => ex
flash.now[:err] = "some error " + ex.message
erb :content, :layout => :mainlayout
end
Any ideas to why this isn't completing when under ensure? I would like to use it as its more elegant.
try to use return erb :content, :layout => :mainlayout read more about ensure here - http://blog.leshill.org/blog/2009/11/17/ensure-with-explicit-return.html
