Not sure what your actual needs are but you can pass instance variables
into the PDF writer just as you can in an normal .erb template/
So anything that you would have done in a normal view file can be done
in the pdf view files.
Try to create it as a standalone first and then integrate it into the
actionlinks of AS.
so I have a print function in my controller:
def some_page
@form = Form.find_by_user_id(current_user.id)
@students = Student.find_by_owner(current_user.id)
end
Inside the page I have several structures typical of a template:
You can call partials:
render :partial=>'hdr_c3', :format => 'pdf', :locals=>{:p_user => @user}
render :partial=>'students', :format => 'pdf', :locals=>{:p_students =>
@students}
You can have loops to access the instance variables defined in the
controller
@students.each do |b|
a_numbers += b.first_name + ": " +
number_to_currency(@form[Form::A_INDEX[n]]) + "\n" unless b.klass_id.nil?
end
You have access to the params[:id] (and everything else in params) to
use in your code
To link to a pdf I use:
<%= link_to(@pdficon+"Print all my personalized Forms", {:action =>
'package', :id => current_user.id, :format => 'pdf'}, :popup =>
Konfig::POPTIONS2) %>
Hope this helps you
