Only the first 10kb or so of each file are saved, then obviously when you try to open them you get the same error as before.

Just info: Bad interaction between session and security
by Jean Jordaan 23 May '03

23 May '03

Hi all I'm posting this in case I can save someone coming later from some grief. I was stumped: playing through a series of forms in my app as manager, everything is fine. But when I login as a different user, Zope raises a KeyError at the final step. This is what I log: ==> var/z2.log <== ------ 2003-05-22T16:43:18 INFO(0) MyDebugLog assessment_add> == state == finish ================------ 2003-05-22T16:43:18 INFO(0) MyDebugLog assessment_add> a_session: {'currentstate': 'finish', 'assessed_path': '/qy/positions/pete_smith_OrganisationPosition_163027/pete_smith_OrganisationPosition_174202', 'assessment_type': 'q_1', 'assessed_type': 'OrganisationPosition'}------ 2003-05-22T16:43:18 INFO(0) MyDebugLog assessment_add> == state == finish ================------ 2003-05-22T16:43:18 INFO(0) MyDebugLog assessment_add> a_session: {'assessment_type': 'q_1', 'currentstate': 'finish'}------ The weird thing is that 'a_session' is only logged *once* for state 'finish' in my script. Yet here it is logged twice in the same second. The first time with all the necessary keys on the session, the next time with keys missing, causing a KeyError. It turns out that a call in my method was accessing an object for which the user doesn't have rights, but Zope showed no trace of this. The result was that Mozilla dropped all authentication info and the request was resubmitted, which triggered the second log: now as an unauthenticated user, without the necessary info on their session. It cost me a good few hours to cotton on .. -- Jean Jordaan http://www.upfrontsystems.co.za

How/where to store information
by Wim Bekker 23 May '03

23 May '03

I want to store some information in a 2x2 array. One index is Products, the other index is Components. The values are revision numbers. Everyday Products, Components and revision numbers can change. Since I'm just a starter, what are the ways to store these variables? Using properties is not the correct way, so I guess using a database? Where can I find the information I need? Wim

Can you tell if it has something to do with the file size? Perhaps the problem files are the only ones over some size, like 64K or whatever. Try saving to disk instead of viewing in the browser - you ought to be able to do that much - then see if the file size is right.

problems with Zope rendering PDF Files
by Williams, Rhian 23 May '03

23 May '03

Hi, Has anyone had problems with Zope not rendering PDF files properly? The pdf files are in a localFS object in Zope and are opened within the browers. Most files are ok but I am recently having problems with a couple of files. I get a "File is damaged and could not be repaired" message when I try to open it within Internet Explorer or Opera. The file is fine when I open it via the acrobat reader. The file is from an external provider so I cannot make changes or try to regenerate the file. Any assistance would be greatly appreciated. Regards, Rhian

Best way of using SMTP server requiring authentication

Mailhost does not appear to make it possible to specify information needed to authenticate to an SMTP server. What is the best way of proceeding when this authentication is required? Thanks!

I did not mean to save it after the browser failed to open the pdf file. I meant to right-click on the hyperlink to the file, and select "Save Link As.." or "Save Target As..." (the exact wording depends on the browser). That would have the browser save the file without trying to display it first. Cheers, Tom P

RE: [Zope] How to access html-objects in DTML or python

When you are creating a page with Zope, there are no "html-objects" to access. They will not exist until the browser displays the page. By this time, Zope has no connection with the page anymore. If you want something to happen in the browser, you will have to write the scripting code to do in _in the browser_. You can have Zope put that code on the page, but Zope cannot interact with the page. The closest you can come to simulating an interaction with Zope is by using another frame. This could be an Iframe embedded in the main page and made invisible by styling. You can load a new page into the frame, and then use Javascript to interact between that frame and the parent page. I doubt that this is what you have in mind, though. (There are browser-specific techniques that you can sometimes use too). Cheers, Tom P

It may have been with Interbase or MySQL. It turned out that I had to use a different format for the connection string. I finally found an example somewhere and it worked when I tried it. Depending on the adapter, often the default string works and you do not need to type one in yourself. Why don't you tell us what database, adapter, version, and OS you are using, along with examples of connections strings that you though should work but do not? Cheers, Tom P
