Yes, I have. I suppose you talk about the dtml document calling <dtml-in expr="childLookup(parentBranch = 'Main')"> It makes no difference. I'm doing all testing as a manager. It seems I have to return an object of a type Zope already knows, something like Results objects returned by ZSQLMethods...but to be honest, I haven't completely figured out how to create my own Results object and it seems a bit of a roundabout way of doing it... andres@corrada.com wrote:

So, have you tried proxying the dtml object as manager to see if the authorization problem goes away?

This is the setup:

**childLookup (python method):**

branches = context.childBranchesLookup(BranchParent = parentBranch) tags = context.childTagsLookup(BranchName = parentBranch) #these above are ZSQL results...

result = context.createNodeObj(branchResult = branches, tagResult = tags)

return result

**createNodeObj (external method, calling createNodeObj):**

class _dummy: def __init__(self, name): self.name=name

def createNodeObj(branchResult, tagResult): c = [] for branch in branchResult.dictionaries(): c.append(_dummy(branch["BranchName"])) for tag in tagResult.dictionaries(): c.append(_dummy(tag["CVSTagNo"])) return c

So the idea is to call childLookup, which passes ZSQL results on to createNodeObj, and createNodeObj generates a list of objects and returns it. I know, I know I could've done it with an external method only...I only learnt that too late. Now I can't work with the resulting list of objects in Zope!

for instance:

<dtml-in expr="childLookup(parentBranch = 'Main')"> <dtml-var name> </dtml-in>

results in:

'Authorization failed. Retry? ' popup in my browser. Then cancelling I get the following trace:

Zope Error

Zope has encountered an error while publishing this resource.

Sorry, a Zope error occurred.

So can't I return a list of objects from an external method?

How will one then get the example of dtml-tree with external methods shown in http://www.zope.org/Members/anthony/tree-coding-tricks to work?

Thanks!

You might take I look at Codebase from Sequitor. Apparently they have made available a python interface. Try http://www.codebase.com/search/ HTH, David Otto Pichlhoefer wrote:

Hello,

I have the following problem. My Zope sits on a Linux machine in a small network with several NT installations. I need to access some Clipper files that reside on one of the NT machines.

No odbc for the rescue. Any ideas from the gurus how to accomplish this?

Thanks,
