I have a form that is creating a ticket model. I am trying to allow
the user to assign employee’s to this newly created ticket model. I
followed the complex form’s railscast, which helped a lot it but it
appears the screencast is for creating two new models, instead of just
creating one model and linking an existing model to it. My problem is
I am just trying to assign employee’s to the ticket model and not
create two new models.
This is the I have so far, which is giving me no errors, it is just
not putting any new data into my employees_tickets table.
TicketsController
class TicketsController < ApplicationController
layout ‘global’
def new @employees = Employee.find(:all) @ticket = Ticket.new @ticket.employees.build
end
def create @ticket = Ticket.new(params[:ticket])
if @ticket.save
flash[:notice] = “Successfully created ticket.”
redirect_to :action => “list”, :controller => “workorders”
else
render :action => ‘new’
end
end
end
Ticket Model
class Ticket < ActiveRecord::Base
has_and_belongs_to_many :employees
end
Employee Model
class Employee < ActiveRecord::Base
has_and_belongs_to_many :tickets
end
Recently I was implementing PDF generation for a project utilizing the
fantastic library Prince XML (http://www.princexml.com). I came across
a blog article with a basic library and helper set for Prince
(http://sublog.subimage.com/articles/2007/05/29/html-css-to-pdf-using-ruby-on-rails
), which provided a great basis. I wanted to make something a little
more generalized and in-keeping the Rails Way, so I have created
‘Princely’, a simple wrapper utilizing much of the code from the
SubImage library but giving it better helpers and pluginizing its
inclusion.
== Installation ==
The first step is to download Prince (Prince - Download Prince 15.1)
and install it on your platform of choice (only Linux and Mac OS X
supported by the plugin at this time). Next, simply install the plugin:
You are now ready to get started using Princely to generate PDF. Note
that Princely is only compatible with Rails >= 2.0
== Usage ==
Princely uses the MimeTypes and respond_to blocks from Rails 2.0 to
add PDF as a render option and a format. Because of this, it’s
incredibly easy to implement a PDF! Simply make your XHTML or XML
template and use pdf as the format (e.g. show.pdf.erb), then add code
similar to this in your controller:
class PagesController < ApplicationController
def show
respond_to do |format|
format.html
format.pdf {
render :pdf => @page.pdf_name,
:template => “show.pdf.erb”, # not required, shown for
example
:layout => false # not required
}
end
end
end
And that’s all there is to it! If you add a .pdf to your properly
routed path, you should be presented with a PDF version of the page
generated by Prince. The README
(http://svn.intridea.com/svn/public/princely/README
) has more detailed usage information.
