Re : Re : [Zope3-Users] Uploading files

2006-06-20 Thread Stéphane Brault
Hi all,
 I'm sorry to bother you with what must be a simple problem but I still can't 
see
 how to upload files with zope 3. If ajax is not a good way to go, how should I 
go ?
 I just need that to upload csv files which I parse to update my database 
(MySQL) and
 to upload image files.
 
 Thanks, 
 
 Stéphane

You could use the Bytes() -schema whose InputWidget is a file upload field by 
default.
The content class or adapter for your form should look like this:

class IMyClass(Interface):
   [...]
   csv=Bytes(
   [...]
   )

class MyClass(object):
   [...]
   get_file(self):
  [... put database code here that returns a csv file - if you like ...]
   set_file(self,data):
  [... data contains you file's content. process it as you like ...]
   csv=property(get_file,set_file)

Just use an editform to get a file upload view.

Regards,

Frank

Re : Re : [Zope3-Users] Uploading files

2006-06-05 Thread Stéphane Brault
Thanks Tarek,
 
 in fact I just need a simple thing:
 the user upload a text file which I then parse and update a database. I also 
need to let the user upload images which I then put in a folder (this will 
probably be done with ftp).
 So my main concern is to let the user upload text files, which I don't need to 
save. I'm sure I only need a simple thing to do but I don't know the 
techniques. Also if there's no simple way in ajax, I don't mind going another 
way, I still need to know how to do it though.

While I hate AJAX with a passion, you could certainly do this. If JS has a way 
to access a local file once it has been selected, then you can use the 
XmlHttpRequest class to PUT the file on the server, for example. I certainly 
would not use JSON for this task.

You cannot upload file directly in javascript, because it can't reach
the file system to get the file (it's all about security)

the recipe is to use an IFrame in your form, to get back the hand into
the client,
then do what you need to do on client side while your file is beeing
uploaded.

What your precise use case ?
