noneType in Step by step tutorial

[jvandal]

Hi,

 I am following the Step By step Guide to Dabo and I got to the "Taking a Test Run"
This is  my flow.
I looked at  the messages but I didn't find a solution I could understand. I am running the Windows Vista
Any help will be appreciated.
Thanks \
Jim

I'm new at this but just went through the tutorial myself.  The NoneType
error is referring to the fact that ClientBizobj doesn't exist I believe.
 Did you forget to add the following to ../biz/__init__.py perhaps?

from ClientBizobj import ClientBizobj
from HoursBizobj import HoursBizobj


I believe that's covered pretty early in the (excellent) tutorial.

I checked the biz init file and I have those statements included. I have checked this several times. I have the database statement in the db folder. ConsultHours.cnxml
Any other suggestions??

Just to be sure - you must also have  ClientBizobj.py in the ./biz directory
with the following code (as indicated in the tutorial):

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import dabo

class ClientBizobj(dabo.biz.dBizobj):
    def afterInit(self):
        self.DataSource = "clients"
        self.KeyField = "pkid"
        self.UserSQL = """select pkid, clientname, attn, rate, street1, street2,
                city, stateprov, postalcode
                from clients
                """


And of course in Python, case is important in both the name of the
file and the name of the class.

        This is because the framework tried but failed to add your bizobj  
into its namespace. My guess is that you are running the Class  
Designer from where that program is installed, but your application  
directory is somewhere else. Dabo tries to add your bizobjs to its  
application object namespace, so that you can refer to them as  
"self.Application.biz.MyBizClass", but when running under the Class  
Designer, the Application is the designer, not your app.

        Sometimes exiting the Class Designer and re-opening the design helps.  
Otherwise, you'll have to run the Class Designer from your app's home  
directory:

cd \Path\to\my\app
python \Path\to\ide\stuff\ClassDesigner.py ui\MyFormClass.cdxml

HI,
Since the purpose is to run main.py I assume that you are telling me to create the step by step running with the path you indicated. ?
Can I put those in a file (how) and run them or do I need to make those statements every time?

My experience so far with ClassDesigner is that you must run the app from
the directory where your .cdxml file is located.  I ran across this problem
when attaching an image - if, as suggested, you store images under the
"resources" subdirectory, then the paths will only work correctly when doing
as Ed suggests.  If you don't, then you might end up where running main.py
works while editing with ClassDesigner doesn't or vice versa.

I installed Dabo at the c: as C:\dabo-0.9.2-win\Dabo\ide\Classdesigner.py
                                                                       \ projects\Hours\biz,ui,db,other
                                                                        \other files
Is this something that can affect the outcome
Thanks,
Jim

I don't think so.  When testing on Windows (I'm creating an app for OSX,
Linux and Windows), I open a command prompt (start -> run -> cmd.exe) and
then cd into the projects ui directory.  From there I type
c:\path_to_dabo_ide_dir\ClassDesigner.py.
