Re: Calling a WSGI application from an action

WebOb specifically tries to reconstruct it, but not for file uploads (simply because I didn't get around to it, because it's harder to construct than a simple POST form). And maybe what you are encountering is this same issue. Hi Ian, thanks a lot for answering my message. One thing I don't understand, is why the POST body gets deconstructed in the first place. I don't have a deep understanding of WSGI yet, but I thought one of its advantages was to allow developers to build arbitrary chains of middlewares and applications that are not aware of each others. So how come Pylons is modifying the POST body in such a way that it can't be used by subsequent WSGI component in the chain? I had a similar problem when mounting Trac inside a Pylons application as a controller. Apparently, at some stage environ['wsgi.input'] was consumed hence POST requests were seen blank by Trac once they reached it. I solved it using this piece of middleware [1] stacked closest to the server [2] to cache input in a regular temporary file so it can be 'rewound' before passing the request to Trac [3]. Hope it helps, Alberto [1] http://beta.toscawidgets.org/trac/twWebSite/browser/twwebsite/lib/inputsaver.py [2] http://beta.toscawidgets.org/trac/twWebSite/browser/twwebsite/config/middleware.py#L99 [3] http://beta.toscawidgets.org/trac/twWebSite/browser/twwebsite/controllers/tracdelegate.py#L16 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

paste.registry as a standalone EGG
Hi, Are there any plans to pull paste.registry out of the Paste distribution into a separate one? I've recently removed Paste's dependency from ToscaWidgets in favor of smaller WebOb and ended up copying the registry.py module almost verbatim which is certainly sub-optimal. I believe the registry is useful enough outside of paste and fits with the general trend of breaking Paste up into smaller pieces. As far as I can tell, paste.registry only needs Paste for the threadlocal (is 2.3 support still needed?) and an import from eval_exception inside get_request_id which could be conditional. If I get a pointer into a way to best remove these deps. I'll gladly do the grunt work of creating a new distribution, graft the registry back into the paste namespace (with a setuptools' namespace packages) and contribute it back. Regards, Alberto -- the humbleness of a warrior is not the humbleness of a beggar. The warrior lowers his head to no one, but at the same time, he doesn't permit anyone to lower his head to him. The beggar, on the other hand, falls to his knees at the drop of a hat and scrapes the floor for anyone he deems to be higher; but at the same time, he demands that someone lower than him scrape the floor for him ... I know only the humbleness of a warrior, and that will never permit me to be anyone's master.

There aren't, mostly because the registry has always made me a little uncomfortable. Usually when separating things out, I like to review the code and have a certain sense that the code is as simple and understandable as it can be. I don't feel like paste.registry is at that point, though of course I would like it to be. I'm not exactly sure what would make it simpler. -- Ian Bicking : [EMAIL PROTECTED] : http://blog.ianbicking.org --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Calling a WSGI application from an action
2008/6/2 Ian Bicking [EMAIL PROTECTED]: You need code that takes req.POST and turns it into the serialized body, so that the WSGI app you are calling can reconstruct that body. I understand that Pylons parses the body of the POST request and turns into a Python data structure. In particular, any uploaded file gets turned into a cgi.FieldStorage. What I need to do is convert it back to its serialized version. Am I correct so far? Then where should I set the serialized version so that it can be used by oher WSGI apps? It seems that request.POST can't be assigned a new value. You'd put a new file-like object into wsgi.input, like: from cStringIO import StringIO environ['wsgi.input'] = StringIO(serialized_body) Great, I managed to make it working. I'll try to get my head around webob and add it there. Thanks a lot. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

AW: How to pass image?
-Ursprüngliche Nachricht- Von: pylons-discuss@googlegroups.com [mailto:[EMAIL PROTECTED] Im Auftrag von deezee Gesendet: Dienstag, 3. Juni 2008 23:05 An: pylons-discuss Betreff: How to pass image? Hello everybody! I'm pretty new in Pylons world - today i downloaded and installed software. So, some stupid question: How to send (simplest way) image from PIL to template (browser) without saving file? I'm playing around helloworld sample, but i want to see picture instead of text. I can generate one by PIL, and send by c.image, but till now i just have PIL.Image.. marker, no image itself. In PHP it's quite simple, don't believe something newer is more complicated.. Inside of the controller action: 1. you generate a image with PIL 2. you convert the stuff to string with a certain format (I do this with reportlab charts like: binaryStuff = drawToString(d, 'png')) 3. you set the content header to the corresponding format (response.headers['Content-type'] = 'image/png') 4. you return the string (return binaryStuff) This controller action is only for serving the image requests! In you HTML (maybe generated by MAKO) you have to have a img - tag which points to the controller action. For example: - action index - serves HTML, and returns HTML with img src=/picture1 - action picture1 - serves PNG pictures A very rough draft, but hopefully points you to the right direction.
