SMTPSenderRefused error
by Ruth Mizzi 17 Oct '03

17 Oct '03

Hi, I'm using a mailhost on my site in order to be able to send out emails. When a user registers into the site I want to validate the email address given to confirm, as much as is possible with a not too detailed function, that the address given is valid. Reading through forums I've concluded that all I need to do is to attempt to send a confirmation or test mail to the given address, if an SMTPSenderRefused error is received then I can assumed that there is something wrong with the mail addrees... the python script I'm using is simply: import smtplib try: Anvil_Page.MailHost.send("This is a test", 'ruth(a)ffff.com') except smtplib.SMTPSenderRefused: get_transaction().abort() return "Invalid email address: please press your browser's='back' key and correct it" else: return 0 The only problem is that when I try to test this script the zope login screen comes up and regardless what passwords and logins I try to enter, including the admin one, I end up with the error: "You are not allowed to access SMTPSenderRefused in this context" Any idea what I've got wrong?

And i get only the result of creGraph (the image) I think the problem is in creGraph, with the REQUET.RESPONSE.setHeader('Content-Type', 'image/jpeg') If you call creGraph from the dtml method you're modifying the content-type for the whole HTML page. This will only work if you do something like: <dtml-var header> <img src="creGraph?param=value"> <dtml-var footer> since the image will be retrieved by itself on a separate HTTP request. > Thank you for the explanation, i will try that. try this instead, is the same in python: python script: creGraphParams parameters: REQUEST param_names=['foo', 'bar'] cgurl = '' count = 0 for p in param_names : if count > 0 : cgurl = cgurl + '&' cgurl = cgurl + p + '=' + REQUEST.form[p] count = count + 1 # if there are no errors should return # something like foo=1&bar=25 return cgurl # end of script in the dtml <img src="creGraph?<dtml-var creGraphParams>"> > Yesterday evening, in > place of returning my image from the external method, i return only the > name of an "external file".

Z2.log logs user as Anonymous
by Ruth Mizzi 17 Oct '03

17 Oct '03

Hi, I've got CookieCrumbler installed with my Zope site in order to carry out user authentication. My users can initally register to the site - they are added to the acl_users folder in this step. From then on they can log into the site as registered users.... all works fine till here. The only problem is with my Z2.log... the zope access log. I'd like to use this to gather some statistics about which users log in most frequently etc. What's happening though is that when a user logs into the site and continues browsing through it, the z2.log keeps logging the user as "Anonymous". The only time this changes is when I use the ZMI and in that case the log lists the user as 'admin'. Can anyone tell me what I'm missing? Cheers Ruth

RE: [Zope] Retrieving a set number of entries
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 16 Oct '03

If you're using DTML, then the batch features of DTML are one way to go ... this however will run the entire query every single time you draw the page ... DTML will then figure out the subset of records to display. If you want to make sure the SQL query itself only returns things that you want in a relevant way, then use the LIMIT/OFFSET clause on your SELECT statement. Then simply pass form parameters around (Index to start, and how many records to show), and feed them to the SQL method as necessary, and you're good to go.

We are using Zope 2.6, Python 2.1.3, and the database is in PostGreSQL 7.3.3. The problem I am having is trying to search the database and return a set number of entries. Like how Yahoo! returns 25 possibilities in it's search per page. Or how Google returns 10. I'd like to know how to code it so that a database search returns a set number of entries found, and can make pages with multiple entries if there's more than the set number of entries on a page. Anyone have any ideas? -- Lalo Castro Programmer/Analyst McHenry Library (831) 459-5208 _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Apache + Zope
by Michael Havard 16 Oct '03

16 Oct '03

I'd like to find a good document on how to serve content from Apache and Zope simultaneously. I already have Apache set up with rewrite rules to a ZOPE/Plone installation that serves our dynamic content. I'd like to be able to move our existing legacy content from our IIS server to Apache until that content can be moved up into ZOPE (after some significant clean up). How does one seemlessly integrate the environments? _________________________________________________________________ Concerned that messages may bounce because your Hotmail account has exceeded its 2MB storage limit?
