Hello!
Thank to Alan Etkin in the spanish group for:
[http://groups.google.com/group/web2py/browse_thread/thread/

+input#1dc875d27dab5c87]
I asked [https://groups.google.com/forum/#!topic/web2py/pcHQx0gV0mo]
This is the solution
## record's id
id = 1
code = db.codigo[id].el_codigo
## the solution
code = code.replace('\r','')
Question:
I feel that this code works but is not quite correct!?
In case you want to reproduce the experiment:
1. Copy to db.py:
db.define_table('codigo', Field('el_codigo', 'text'))
2. Open appadmin and in db.codigo insert:
##
from gluon import *
def testFunc(globales=''):
##redirect('testImportCode')
##redirect('index')
cont = globales['testtable']()
return dict(cont=cont)
##return "spam from database! works!"
class testClass:
def testMethod(self):
return "eggs from database"
3.Remember the recors's id
4. Copy to default.py:
##
def farg():
code = \
"""
def testFunc():
return "spam from farg!"
class testClass:
def testMethod(self):
return "eggs from farg!"
"""
return code
def testtable():
table = SQLTABLE(db(db.codigo.id>0).select())
return table
##
## call this function
##
def testImportCodeFromDataBase():
# Example
## change this id
id = 1
code = db.codigo[id].el_codigo
## the solution
code = code.replace('\r','')
## experimen
##code = code.replace('\r\n','<-br->')
m = importCode(code,"test")
## Atention:
##
## import copy
## arg = copy.copy(globals())
arg = globals().copy()
spam = m.testFunc(globales=arg)
o = m.testClass()
eggs = o.testMethod()
cont = DIV(P(m), P(spam), P(o), P(eggs))
##cont = code
return cont
def importCode(code,name,add_to_sys_modules=0):
"""
Import dynamically generated code as a module. code is the
object containing the code (a string, a file handle or an
actual compiled code object, same types as accepted by an
exec statement). The name is the name to give to the module,
and the final argument says wheter to add it to sys.modules
or not. If it is added, a subsequent import statement using
name will return this module. If it is not added to sys.modules
import will try to load it in the normal fashion.
import foo
is equivalent to
foofile = open("/path/to/foo.py")
foo = importCode(foofile,"foo",1)
Returns a newly generated module.
"""
import sys
import imp
module = imp.new_module(name)
exec code in module.__dict__
if add_to_sys_modules:
sys.modules[name] = module
return module
5. run [...]/default/testImportCodeFromDataBase
Can someone switch on the light.PLEASE.
