Subject: Re: [dabo-users] codepad pasted: Error in _getRecord() of dCursorMixin()
AFAIK web2py has its own ORM and is streamlined to use it - ----------------- My comment:-- I respect web2py's DAL. But still it is not as comprehensive as dabo's bizobj. Maybe, DAL (or its equivalent in django) is sufficient for any rudimentary 'blog' or CMS type apps. But when it comes to business class apps like ERP solutions, bizobj is the only lifesaver (for me, at least). One who has worked with vfp's CA class can understand it well. If DAL is a sharp knife, BizObj is a swiss army knife. ----------------- the DAL is a function from web2py, I don't see where it is imported. ----------------- My comment--- You are right. That's what I said in my mail, 'the pasted code on codepad cannot be run standalone' ----------------- Are you sure it is "known" when the error occurs ? ----------------- My comment-- The error in codepad is because the DAL is not imported. My real problem is different (which is given in the original post). While importing parent bizobj, the error occurs. ----------------- How do you plan to use web2py and DABO together ? ----------------- My comment--- I will not break any logic in web2py. Its DAL layer will be untouched. What do I need for constructing a bizobj, connecting to DB & manipulating records? 1) dabo folder & MySQLdb -- I keep a copy of dabo folder it in 'site-packages' folder of web2py. I import the same. MySQLdb is installed already. 2) connection parameters are readily available since I store them in 'session' storage object. e.g. 'session.usrnm' contains login name, 'session.pswd' contains password, etc. 3) This way, bizobjs require only connection parameters. After that, bizobjs functions independently. The resultset is used to populate the widgets on web forms. Values from widgets, after form.accepts:, can be used for saving data in DB via bizobj's full-fledged machinery of methods. ---- -Vineet ----- curious thomas Vineet Deodhar schrieb: Dear John & other list-members, I have pasted the code on http://dabo.codepad.org/FBIoYWUe But it can't be run as it is.

As stated earlier on this list, I am using standalone 'bizobj' class with 'web2py'. I imported the entire dabo folder in my app. Database server is MySQL DB. There is a parent bizobj named as 'statBizObj'; (it has a child bizobj named as 'distBizObj') Upon encountering 'statBizObj.requery()' statement, exception is thrown when it runs 'requeryAllChildren()' method. I debugged via 'PyScripter' & could see that the bizobj can talk to the database & fetch rows.
