That's right - I expect that it could be useful for a few products. I can see XMLDocuments having a default of 'text/xml', but I suspect that a lot of products won't really have to care. Things that have no real similarity to conventional "pages" (like database connection objects, etc.) are probably useless to a robot that works with "pages" anyway, so they are better off sending a default non-committal response like "application/octet-stream".

Re: [Zope] Q: Accessing ZSQL methods from Python
by Dieter Maurer 08 Jun '00

08 Jun '00

a.wacknitz(a)francotyp.com writes: > my question is what type or value is returned by a ZSQL method that is > invoked from Python? ZSQL methods return "Shared.DC.ZRDB.Results.Results" instances. Such an instance essentially behaves like a sequence of objects each describing one result row. These objects have been set up such that a column value can be accessed as attribute with the column name. Thus, "results[i].column" gives the value of "column" of the i.th row. How to determine, how "Null" values are recognized, is less a Zope than a database adapter question. I would expect, that most (if not all) database adapters will map SQL Null to None. However, even some well established SQL databases do not treat Null standards-conform but represent it as the empty string. Then, the database adapter has no chance to map this to None but must use '', too. Dieter

Re: [Zope] Help on synchronous methods?
by Dieter Maurer 08 Jun '00

Craig Allen writes: > How can I synchronize external method completion with DTML method invocation? > [and do I need to?] A single request is executed by a single thread. Inside this thread, all invocations are serial (and therefore synchronized). Different requests may be executed by different threads. The operations in different threads are usually not synchronized. You may use services of the Python threading module (in external methods) to provide explicite synchronization. Dieter

Re: [Zope] Several users having problem accessing field names of a ZSQL Method

It tells you, that "SQL.names" is the problem. Because, you did not enclose it in "...", it is treated as a variable name (i.e. equivalent to <dtml-in name="SQL.names">) and such a variable does not exist ==> KeyError. What you probably wanted was: <dtml-in "SQL.names"> Note the double quotation marks. In this case, "SQL.names" is not treated as a variable name but as a Python expression. Probably, this will not work, either. There are 2 further problems: 1. "SQL" must probably be called 2. "names" is a method and not an attribute; it must be called, too. Try something like: <dtml-let result=SQL>  <dtml-in "result.names()"> <dtml-let .... vvalue="result[0][_['sequence-index']]"> .... Dieter

dtml-tree with data from multiple tables
by Lance Kurisaki 08 Jun '00

08 Jun '00

I'd like to generate a tree with data from different SQL tables depending on the tree level. In other words, the first level data comes from one table, second level comes from another. How can the branches_expr expression determine what the current tree level is? Can I pass a parameter to let me know the current level? I tried the following, but it didn't work... <dtml-tree id=name branches_expr="child_lookup(_['tree-level'])"> Thanks, Lance __________________________________________________ Do You Yahoo!? Yahoo!
