Can anyone offer any advice? You should search the (searchable) list archive. You will find at least one thread that discusses this issue. You may also find a HowTo at zope.org. Dieter

Can't be! You can use REQUEST in a PythonMethod, too. Either pass it explicitly as parameter or use "self.REQUEST" to access it. Dieter

Zope is not getting MySQL SELECT results ...
by Gerald Gutierrez 23 Jan '01

23 Jan '01

Hi all. I have set up, in a clean Zope installation, a MySQL database adapter. My connection string is "test test test", indicating a user test with password test connection to the test database. The adapter indicates that it can connect to the database, and I can send queries to the database. CREATE TABLE, INSERT, UPDATE, and other queries work just fine through the "test" tab of the adapter management interface, but it does not seem to be able return any data through a SELECT query. This does not work in the "test" table nor in a SQL method. Using a query, such as "select * from test", it always replies with: -------------------------------------------- There was no data matching this My Query query. SQL used: select * from test -------------------------------------------- I know the queries are reaching the database, because if I give it a bogus command, it gives me an error, and if I give it a command that affects the data, I can see that reflected in the database itself with MySQL's "mysql" client. So what is a problem here? As another test, I tried out the MySQL-python module; it works just fine. I'm using Python 2.0, Zope 2.3b2, ZMySQLDA 1.2.0, MySQL-python 0.3.0. Thanks for any help. Gerald.

PythonScript bug?
by Tim Moore 23 Jan '01

23 Jan '01

I have a small python script method which works fine unless I bind the Namspace to a variable (even if I don't actually use the variable), which causes a MemoryError that appears to be due to deep (infinite?) recursion in the __render_with_namespace__ method (Bindings.py, line 355).

This must be "NameError 'attach_file'", right? > Do you know a solution to this? because when I dont specify anything in a > field zope just dont know about it... Apparently, browsers behave differently. My Netscape 4.7 interpretes an empty file control as successful and sends the corresponding name/value pair (with empty value). To handle both behaviours, you can use: <dtml-unless "REQUEST.form.has_key('attach_file') and attach_file.filename">  </dtml-unless> Dieter

But > what if there are more (or less) elements in path_to_handle? The easiest answer to these types of questions are recursive functions. You may use a "dtml-in", too. Like that: <dtml-call "REQUEST.set(curr__,lfs)"> <dtml-in path_to_handle> <dtml-call "REQUEST.set(curr__,curr__[_['sequence-item']])"> </dtml-in> <dtml-var "curr__.fileids"> Dieter

Property sheet feature request
by Tim Moore 23 Jan '01

23 Jan '01

It would be nice to be able to reorder properties in a sheet, maybe using something like the "First" button in the views screen. I'd submit a patch myself, but I'm still figuring all this out so it would hopefully be quicker for someone else more familiar with the code to add that. thanks! -- Tim Moore

Re: ZClasses and "title" property
by Aaron Louie 23 Jan '01

23 Jan '01

I think the problem goes deeper than that. Zope 2.3x no longer allows the setting or creation of any property called "title" for new ZClasses. Period (At least, not in the same way it used to). Try it for yourself. If you follow the steps in the "ZClass Properties" How-to (http://www.zope.org/Members/lstaffor/zProperties) you'll find that Zope 2.3x gives a "The id 'title' is invalid--it is already in use" error when you try to create a property called "title". Fine, you say, it's already there by default, right? Finish out the How-To, setting all the proper permissions, modifying the addForm and the constructor to accomodate your other properties. Then try creating an instance of your new class and setting the 'title' property through the addForm. The title will not be set when you hit 'Add'. The field will remain empty... Of course, the How-To above worked just fine in 2.2.5. Doesn't work anymore. There is no longer any default place to set the title in a new ZClass and the title property cannot be set thru DTML. (Haven't tried it in Python yet) Is this a bug or am I missing something? ajl >> I guessed it was something like this, so this leads me to two followup >> questions. >> >> 1) I'd be happy to use the built-in title property assuming that it >> won't cause some kind of problem.
