[Zope] dtml-let and product
I have a simple test Zope product inheriting from Cacheable, PropertyManager and SimpleItem. Say I have a dtml method at http://myzopeinstance.com/testdtml with contents I'd like "myvar" to be available in the__call__ method of testproduct. I don't know how to do that. Here's my testproduct __call__ method: def __call__(self, client=None, REQUEST=None, **kw): foo="1. client:"+str(client)+"" \ +"2. REQUEST:"+str(REQUEST)+"" \ +"3. kw:"+str(kw)+"" \ +"4. getattr(..REQUEST..):"+str(getattr(self, "REQUEST", None))+"" \ +"5. getattr(..client..):"+str(getattr(self, "client", None))+"" \ +"6. getattr(self, myvar...):"+str(getattr(self, "myvar", None))+ "" \ +"7. aq_get(self, myvar...):"+str(aq_get(self, "myvar", None))+ "" return foo >From poking around I was expecting "myvar" to be accessible somewhere from >that list either directly or as an attribute of one of the objects, but it's >not. Every call (via a web browser) displays None for every line except #4, >the getattr(self, "REQUEST", None) statement. Containment acquisition works more or less the way I would expect, i.e. if myvar is a dtml method in the same folder then the text "hello world" shows up on lines 6 and 7. (I don't understand though why the REQUEST object is always None; I thought when a DTML method calls another object the client and REQUEST parameters are passed in.) I'd appreciate it if someone can explain to me how things work and what I'm doing wrong. Looking for last minute shopping deals? Find them fast with Yahoo!

[Zope] dtml-let + 'expr=' possible?
Hi, I have one quick question about the 'let' tag; gives me the value 'class52225'. Is there anyway I can use the 'let' tag to push this onto the namespace stack? I was thinking something *like*; The python method, classcode_to_table, takes in a string, alters it and returns it. This is going to be an argument for some ZSQL methods and some Python methods.

[Zope] dtml-let and quoting(?) or forcing to string
All, I've just setup a test Zope installation. So far, very impressive. I'm using a Postgresql database containing a network hierarchy (basically, a table with a "network" column, and a "parentnet" column). I'm trying to display this with a tree view, using the following DTML: Where the network "0/0" is the pseudo-parent of every other network. The problem is, python (or DTML, I don't know) interprets this as a divide by zero, and it fails. The other alternative "0.0.0.0/0" also fails: Expression (Python) Syntax error: invalid syntax , for tag , on line 15 of test_html (I'm doing all this through the web management interface). I'm not familiar with Python (yet - the book is on it's way) but in the command-line interpreter, this works fine: >>> "0.0.0.0/0" '0.0.0.0/0' >>> "0/0" '0/0' >>> I need to cast the value to dtml-let to a string. How? I know how to do this in Perl/C/Java/Pascal, but it's not obvious to me why this isn't working.

Explanation: Python distinguishes between expressions which can be "eval"ed and commands which can be "exec"ed. Assignments are commands, as are definitions, if, for, while constructs. Zope uses "eval" to evaluate expressions in DTML-tags. "eval" raises a SyntaxError when confronted with a command.

Re: [Zope] dtml-let help
I tried the same thing, it doesn't work (or at least, I haven't found a way to
make it work).
What I do now is use REQUEST.set('totalActive',0 ) and
REQUEST.get('totalActive') when I need the value. The other alternative is to
write it in a python method.

Luis.
