[Zope] Displaying a pdf file.

[David Hassalevris]

Michael,

Could you be more specific?  What is it *exactly* you cannot do?
Your question raises alot of issues.

if you just want to know what do once you have access to the correct pdf then do something like (roughly in code)

*yourExternalPythonScript*
def someName(self,REQUEST,RESPONSE):
      parent = self.aq_parent
      res = parent.yourZsql(pdf_id = REQUEST[pdf_id])  # get the pdf from your DB
      record = res.dictionaries()
      for n in record:
          pdf = record['PDF']
      
      RESPONSE.setHeader('Content-Type','application/pdf')
      RESPONSE.setHeader('Content-Length',len( pdf ))
      RESPONSE.write( pdf)

*the calling dtml script that displays the pdf*
<dtml-call "REQUEST.set('pdf_id',pdf_id)">
<dtml-call "yourExternalPythonSCript(PARENTS[0],REQUEST,RESPONSE)">

  Subject: [Zope] Displaying a pdf file.


  Hello,

  What is the best way to display a pdf file in a zope application.  I may select the file from an oracle database of get it from a file system.  I'm not sure at the moment.

  My Zope Bible book shows how to upload a pdf file from a filesytem then view it.  But in my case the pdf I want to view is based on an ID entered by the user.  There may be many different pdf and I can't upload them all.

  I want to be able to 
    1) if the the pdf is on server then
           view (\docs\my.pdf)  using the correct application type

  or
    2) if I select the pdf from an oracle table (stored as a BLOB)
         <dtml-in sql-get_pdf>
               somehow display the pdf
         </dtml-in>

  Thanks for your help

  Mike Guerrero
