[PythonReports-users] Adding a Field to Detail band

[Werner F. B. <wer...@fr...>]

When I do:

1. Click on "New Template"
2. create "data"

 >>> data = ds.query(db.Cellarbook).all()
 >>> data
[Cellarbook(storagelocation=None), Cellarbook(storagelocation=None), 
Cellarbook(storagelocation=None), Cellarbook(storagelocation=None), 
Cellarbook(storagelocation=None), Cellarbook(storagelocation=None), 
Cellarbook(storagelocation=None), Cellarbook(storagelocation=None), 
Cellarbook(storagelocation=None)]

3. Click on "New Field"
4. Click within "Detail" band I get this exception:

wx._core.PyAssertionError: C++ assertion "Assert failure" failed at

Any hints on what I am doing wrong?

Robin and Alex,

I had a reply from both of you, I'll copy both lists on this.

Quote of Alex's reply:

I have wxPropertyGrid installed as separate module:
http://wxpropgrid.sourceforge.net/

I will give this a try and see, I assume you use version 1.4?

Yes, 1.4.15.

I have just got mail from author of the editor.  He did not reproduce 
the exception (neither did me), but he thinks he nailed the problem 
down.  The exception is about duplicate name, and the assertion fails 
when we add a category named "data" when there already is a field named 
"data" in category "field".

It looks like a bug in wxPropertyGrid: logically, field names and 
category names would go to different name spaces.

And you get the exception because you use development version of 
wxPython which has assertions enabled.

End Quote

This is what I get when I run it with 1.4.15 installed into wxPython 
2.8.12 in the prop grid, so it confirms that there is problem with 
duplicate name, hopefully fix will make it into 2.9.5:-) .

Starting with 2.9 all builds will have assertions enabled by default, 
and IMO it is wrong to ever turn them off for wxPython.  If something 
triggers an assertion then it means that the calling code has done 
something wrong and it is much nicer to get an exception raised than to 
silently ignore it or possibly crash.

Is there a ticket for it in wx's Trac?  I think 2.9.5 is coming pretty 
soon so it may not make it in unless Jaakko jumps on it right away.

I believe this is fixed with
