[Zope-dev] ZDiscussions

[Pearson, Brian Edward (GEA, 056278)]

> All,
> 
> Have been trying to add File Attachment functionality to the ZDiscussions
> Product.  Thus far, I have modded the ZDiscussions.py file, specifically
> the ZDItem class's __init__ method, to accept one extra parameter called
> file.  The corresponding DTML-Method (postForm) within the ZDiscussion
> object has been modded to include a FILE input field.
> 
> To facilitate the file handling, I am using the Squishfile.py module.  All
> is working well, and via a new def attachment(self) method that was added
> to the ZDiscussion.py module, I am able to return the file to the browser.
> 
> Herein lies the problem.  How can I reference the file via an HREF?  With
> the following DTML:
> 
> <dtml-if attachment> 
> 	<b>Hello there</B>
> 	<tr><th bgcolor="#d0d0f0" align=left>Attachment:</th><td>
> 	<dtml-in attachment>		
> 		<A HREF="./<dtml-var file_name url_quote>">  
> 		<IMG SRC="<dtml-var SCRIPT_NAME >/<dtml-var icon >"
> HEIGHT=16  
> 		  WIDTH=16 BORDER="0" ALT="Click to download
> attachment"></A>    
> 		<A HREF="./<dtml-var file_name url_quote>">  
> 		<dtml-var file_name></A>   
> 		<dtml-var file_kbytes>KB (<dtml-var file_bytes> bytes)<BR>  
> 	</dtml-in attachment></td>
> </dtml-if>
> 
> This of course references the file object as
> absolute_url/ZDItem_id/file_name.  This same reference url is used in the
> Squishdot product when displaying a link the user may click on to download
> the file.  However, in my implementation it is not referencing the file.
> 
> The only way to reference the file is to use <dtml-var attachment>, which
> means that the file will be streamed to the user as soon as they click on
> the message thread, obviously not the way I would like to handle the
> situation.
> 
> Do I need to include the file object as a property of the message?  I
> thought by including the file object during the creation (__init__) method
> of ZDItem this would be handled.
> 
> Any/all assistance would be greatly appreciated.  Also, if I am crazy for
> doing this please let me know.  Perhaps a new ZDiscussion already exists
> that supports attachments?
