Re: [Zope] Help with session data and redirects

Zope 2.6.1 running under IIS on a Windows 2000 Server, with PCGI. Client browser is IE v5.50.4522.1800 running on Windows 2000 Professional. Also tried with Mozilla 1.0 under Debian. Gathering this info for you made me think about the PCGI interface, and I discovered something interesting. The redirect works great when I'm going direct to Zope port 8080 (not using PCGI). It manifests the initial request problem when using the PCGI interface. In fact, that's why Konqueror worked. I was going direct to port 8080 when I was trying Konqueror.

Thanks, Chris, for the quick reply. I tried both of your suggestions: the random query string and the setHeader statements in the ZPT. They both improved the situation in that requests after the initial one are now returned properly. However, the very first request still returns the "Problem: no session object (redirectTest)" message. By the way, instead of a response.redirect, if I return the page template directly in the script with a statement like "return container['view_session_obj.pt']()", it works perfectly. Unfortunately, I need the redirect because of the way my actual page template works.

To verify, cause the createSessionAndRedirect to generate a "random" query string like this: session = context.REQUEST.SESSION sessionObjName = 'redirectTest' session.set(sessionObjName, sessionText) return context.REQUEST.RESPONSE.redirect(context["view_session_obj.pt"].absolute_url() + '?abc=%s' % context.ZopeTime().timeTime()) This should prevent browsers from returning a cached page.

Help with session data and redirects
by Brad Powell 15 Apr '03

15 Apr '03

I have a problem where session data does not appear to be updated when the setting of the session data is followed by a response.redirect in a Python script. A browser refresh is required to get the correct data displayed. This happens on both Zope v2.5.1 and v2.6.1. It also happens with IE and Mozilla browsers; but, interestingly, it does not occur with the Konqueror browser. This led me to believe it was a browser issue, but no matter what options I try in IE, I cannot get it to work. I thought it might be an issue with the browser cache settings, but, again, no matter what I try I get the same result. I've included a test script and page template that demonstrates this problem. When I go to url "sessionCreateAndRedirect?sessionText=123", I get the message, "Problem: no session object (redirectTest)." If I then refresh the browser, I get "123" displayed, which is the correct response. Subsequent calls to the url with different values for sessionText returns the previous session value, until I do a browser refresh. Any assistance, guidance, wisdom, etc. on this matter would be greatly appreciated. ## Script (Python) "sessionCreateAndRedirect" ##parameters=sessionText ## session = context.REQUEST.SESSION sessionObjName = 'redirectTest' session.set(sessionObjName, sessionText) return context.REQUEST.RESPONSE.redirect(context["view_session_obj.pt"].absolute_url()) ## Page Template "view_session_obj.pt" ## <html> <head> <title tal:content="template/title">The title</title> </head> <body> <tal:block define="global sesObj request/SESSION/redirectTest | nothing"></tal:block> Problem: no session object (redirectTest). session obj contents </body> </html> Brad

>does anybody know how i can make a link that will automatically find >objects and catalog them? so instead of the users doing it manually all >they have to do is click the link. I have a XRONDTMLMethod that makes it automatically every X hours. You could copy the code there in a DTMLMethod and call it when you like (or in a python script, too). This is the piece of code: <dtml-call "catalog.manage_catalogClear()"> <dtml-call "catalog.manage_catalogFoundItems(REQUEST,RESPONSE,URL1,URL1+'/catalog', obj_metatypes=['Folder'])"> 'catalog' is the name of the ZCatalog object, which is located in the same folder as the XRONDTMLMethod. If you want to catalog objects of type 'File', change the 'Folder' for 'File'. Igor Leturia

automate Find and Catalog
by michael.ta�ag 15 Apr '03

15 Apr '03

hi! does anybody know how i can make a link that will automatically find objects and catalog them? so instead of the users doing it manually all they have to do is click the link. Find objects of type: File with ids: <default> containing: <default> expr: <default> modified: <default> where the roles: <default> have permission: <default> If a user does it manually, he only has to select file object types. basically, everything else is the default.

Sending DB data via SESSION manager
by Braun Brelin 14 Apr '03

14 Apr '03

[I originally sent this e-mail to the Zope-DB list, but in reviewing it, this may be more of a question for the general list] Hello, I've built a formulator form that connects to a database to populate many of the fields in the form. I'm using the MySQL DB adapter and I've written a python script to access it and return the data via the SESSION Manager like so... for (key,value) in recordset.items(): context.REQUEST.SESSION.set(key,value) This, however isn't precisely what I want. If I create two separate instances of the formulator form (i.e. I do a copy/paste from the master form object into my own folder more than once) The second form gets the same datavalues automatically rendered into the field as the first form. What I want, instead, is in the SESSION object to set a dictionary where each key would be the form ID and the value would be another dictionary containing the database field values. How do I go about doing this? I tried doing something like this: context.REQUEST.SESSION.set(MyFormsDict,{}) but that fails with an "unhashable type" error. Is what I'm attempting even possible with the SESSION object? Any thoughts? Thanks, Braun Brelin ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
