python Help with classes

[António Ramos]

hello i tested this simple code outside web2py

class a():

    def a1(self):

        temp=getattr(eval("b")(), "b1")('testing result')

        return temp

    

class b():

    def b1(self,param):

        s=somevar2.somesubvar1

        return param

print a().a1() 

if i remove s=somevar2.somesubvar1 the code prints "'testing result'" otherwise i get this error

global name 'somevar2' is not defined

I´m using this kind of code with virtual fields like this

db.py

from wf_validates import Validate

db.define_table(

"status",

...

Field.Virtual('isavailable', lambda row: Validate().status('status','isavailable',row,db)),

)

wf_validates.py

class Validate(object):

def status(self,table,field,row,db):

wf=db.workflows(id=row[table]["workflow"])["workflow"]

cb=getattr(eval(wf)(), table+"_"+row[table]["title"].replace(" ","_"))('xx',db)

return cb

class Ficheiros(object):

def status_Draft(self,row,db):

session=current.session

return True

here session=current.session is the offending line probably because session is not available.

So far so good.

The problem is that it does not throw any error and i was chasing it for too many time until i discovered it because the field "isavailable" was not created but the row object was created.

Why web2py does not generate an admin error with

global name 'session' is not defined  ???

Regards

this is my real code in wf_validates.py

from gluon import current

class Validate(object):

def status(self,table,field,row,db):

wf=db.workflows(id=row[table]["workflow"])["workflow"]

if wf in ["Ficheiros","Load","Pessoa"]:

cb=getattr(eval("Ficheiros")(), "status"+"_"+"Draft")('xx','db')

return cb

else:

return ""

class Ficheiros(object):

def status_Draft(self,row,db):

db.log.insert(msg="status_draft")

session=current.session

this_time=datetime.datetime.utcnow() +datetime.timedelta(hours=-1)#session.utc)

check_time=this_time.replace( hour=18, minute=0, second=0, microsecond=0 )

return this_time>check_time

return True

What is the traceback?

[António Ramos]

There is no traceback. the record is returned like this  if i remove  session=current.session

<Row {'completion': '0', 'help': 'This document is still in Draft.\r\nYou should send it to Approval', 'workflow': 4L, 'workflow_comment': <Set (workflow_comment.step = 8)>, 'titleenter': 'Review', 'title': 'Draft', 'titleaction': 'Draft', 'entities_extra': <Set (entities_extra.status = 8)>, 'entities': <Set (entities.status = 8)>, 'rgb': '#00c0ef', 'rules': <Set (rules.step = 8)>, 'details': 'Person', 'id': 8L, 'isavailable': True, 'icon': 'fa-user', 'button': 'btn-info btn-xs', 'color': 'bg-blue'}>

but if i have 

session=current.session inside the  status_Draft  function  i get this result 

<Row {'completion': '0', 'help': 'This document is still in Draft.\r\nYou should send it to Approval', 'workflow': 4L, 'workflow_comment': <Set (workflow_comment.step = 8)>, 'titleenter': 'Review', 'title': 'Draft', 'titleaction': 'Draft', 'entities_extra': <Set (entities_extra.status = 8)>, 'entities': <Set (entities.status = 8)>, 'rgb': '#00c0ef', 'rules': <Set (rules.step = 8)>, 'details': 'Person', 'id': 8L, 'isavailable': True, 'icon': 'fa-user', 'button': 'btn-info btn-xs', 'color': 'bg-blue'}>

there is no "isavailable"

What is the traceback?

[Jim S]

there is no "isavailable" 

Yes there is.  Did you paste the wrong result?   'isavailable' is True in the second result set too.
