Can't open file via Python
by Geoff Armstrong 29 Mar '01

29 Mar '01

Hi, I want to open and read a file via Python; but whether I try to do it via a Python method or an external Python script stored in the Zope extensions folder, the result is the same. I'm using this code for a file name I pass in as a parameter: data = open(file, 'r') return data ...and I get this result: Error Type: NameError Error Value: open The Python method has a proxy role of Manager and so does the DTML script which calls it. The same thing happens when I try read or readline. I know Python methods are limited in certain ways; but external scripts? Please help Thanks Geoff Armstrong

RE: DTML documents killing Zope (was RE: [Zope] ZServer dying)

Actually that's not true - it does die sometimes, but more often it hangs.

The application is... complex. I'll try to replicate it the behaviour as a smaller sample tomorrow...

Nothing shows up in the log? Is there a core dump? I can't replicate this using the latest from the 2.3 branch. Could you send me a .zexp? Cheers, Evan @ digicool

Hello Zopers, is there a Product called Tracker like the issue tracker seen on the Zope homepage ? If I search Tracker AND Product, nothing similar is found. Is this product closed to Zope ?

Debugging MySQLDA
by Peter Parnes 29 Mar '01

29 Mar '01

Hi Yet another MySQLDA newbie question :-) Is there a way to get some debug information from MySQLDA? My problem is that select * from mytable always produces nothing from a table containing data (verified by talking with the mysql server directly). It doesn't matter if I test it via the test method on the connection or via a ZSQL method. Please help yet another MySQLDA newbie :-) /P

by Angie 29 Mar '01

29 Mar '01

This problem troubled me for few weeks, i really dont know what and where is goin wrong below is my dtml to display the Previous record <dtml-in b previous size=5 start=query_start> <td ><font class="next25"> <a href="<dtml-var URL><dtml-var sequence-query >query_start=<dtml-var previous-sequence-start-number>" style="text-decoration:none"> Previous <dtml-var previous-sequence-size> record(s)<< </a> </font></td> </dtml-in> 'b' is my search sql method, because i got 2 searching key so i have to create 3 search sql method to search my record inorder to select one from these 3 sql methods i used dtml to select from 3 search sql methods, as follow: <dtml-with "Search"> <dtml-call "REQUEST.set('b','')"> *assign a variable 'b' <dtml-if "_['custname']!='' and _['custid']==''"> * if custname is not empty and custid is empty <dtml-call "REQUEST.set('b', sqlSearchcust3)"> * assign b as sql method named 'sqlSearchcust3' <dtml-elif "_['custid']!='' and _['custname']==''"> * if custid is not empty and custname is empty <dtml-call "REQUEST.set('b', sqlSearchcust2)"> * assign b as sql method named 'sqlSearchcust2' <dtml-elif "_['custid']!='' and _['custname']!=''"> * if custid is not empty and custname is not empty <dtml-call "REQUEST.set('b', sqlSearchcust)"> * assign b as sql method named 'sqlSearchcust' <dtml-elif "_['custid']=='' and _['custname']==''"> <dtml-var "searchallcust"> * call the sql method which select all records. </dtml-if> </dtml-with> so far it can return the correct result for me, but i'm not sure whether is this function affect my Previous record please let me know my problem as soon as possible.

Dimitris, <dtml-in "['Jim', 'Alan', 'Bob']"> hello <dtml-var sequence-item> </dtml-in> NOTE: the <dtml-in "PYTHON EXPRESSIONS ARE IN QUOTATIONS"> also note how sequence-item is NOT in quotes, the sequence-item variable is understood in the DTML namespace but not in the python namespace. if you tried <dtml-var "sequence-item">, your essentially saying, print sequence - item and you will get a NameError. try this: <dtml-call "REQUEST.set('sequence', 2)"> <dtml-call "REQUEST.set('item', 1)"> <dtml-var "sequence-item"> sequence=2 item=1 print sequence - item <dtml-with friends>  <dtml-in ['Jim', 'Alan', 'Bob']>  <dtml-var sequence-item>  </dtml-in> please look at the <a href="http://www.zope.org/Members/michel/ZB/">ZOPE book</a>. its full of goodies. you kinda have to learn a little about python to be productive in ZOPE (dont worry Python is the easiest language I've encountered), but you will constantly trip over Python vs DTML (hurdle 1) and then mastering The Namespace (hurdle 2), then armed with that you can work on your Acquisition (hurdle 3, which cant be fully understood w/o the previous 2 steps, IMO). ~runyaga

Hope this is a simple question... Is there a simple way to change what I'm getting in my webserver log (I'm just using Zope as http server). Specifically, I'd like to get the login IDs in the log entries. ----------------------------- - John Maxwell jmax(a)portal.ca

External program execution - simple solution?
by Danny William Adair 29 Mar '01

29 Mar '01

I want to execute my logfile analyzer from within Zope and then access the result files through LocalFS. The latter part is very easy, of course, and works fine, but is there a simple solution to executing an external program? (lying under INSTANCE_HOME) Thank you very much in advance, Danny
