We have a section of our site delivering online classifieds which are imported from text file into a Microsoft Access2000 DB and retrieved using ZSQL methods connecting to Access with a ZODBC adapter. Works fine. Most of the expensive ZSQL methods are cached in the Advanced tab. To make the switch to MySQL, I copied the whole Classifieds folder and renamed it. Then created a MySQL connection to the new database and went into each ZSQL method and pointed them to the new MySQL DA. I checked the caches and they are still there. Problem: Even for one user while testing, the site section is VERY SLOW. Our admin says while monitoring the MySQL DB the connections go way up and it loads up the server. Question: Are the caches 'moving' along with the ZSQL methods when the DB connection was changed? Grasping at straws but it should be faster than using Access. The other site we converted to MySQL from Access did not have the problem and never thought to check the caches...it just worked and was much faster. Any ideas or am I just missing something?

Hi Everyone,

Hello

I am fairly new to Zope and I need some assitance on something that I know is fundamental so please don't beat up on me too bad ;-)

I haven't been a member of this list for too terribly long, but the folks here seem to be pretty darn friendly.

I am try to open a file with a Python Script in Zope for content manipulation. This is a text file, I basically want to read a number, operate on it and write it back out. However when I try to get my file handle I get;

You are going to need to use an External Method (or a Product) for this. The Zope based Python scripts only offer a "safe" subset of Python. Opening files on the filesystem is not a part of this "safe" subset.

file=open("/home/chris/misernumber", "r+")

Zope Error

Zope has encountered an error while publishing this resource.

Error Type: NameError Error Value: global name 'open' is not defined

I tried creating the file as a Zope object but I get the same error. Again I know this is fundamental. If ya'll can help me with this, or at least point me to some documentation it would be deeply appreciated.

There probably is a way to do this with Zope objects, but it wouldn't be using open(). There is a whole slew of methods for manipulating Zope objects, check the Zope API section in the Zope Book. Depending on what you are actually trying to do there might be a more Zope-like way of accomplishing it than with the External Method hammer, but without knowing what you are trying to do it is hard to guess what that more Zope-like thing should be.
