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 to get a file upload view.

Re : Re : [Zope3-Users] Uploading files
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.

Re : Re : [Zope3-Users] Uploading files
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.

Thanks Stephan, could you indicate me another way to upload files ?

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.
