ok, i am stuck. i have studied run_controller_in and restricted and i
tried some test code attempts and i am stuck. so here is some sample code:
xx2 = """
def lucas53():
harry = (4+16)/2
rtn = dict(harry=harry)
return rtn
"""
and under a web2py controller function:
env = {}
exec xx2 in e
It executes the code in the environment passed to it. If the code adds
objects to the environment, you can grab them from the environment after
execution. Look at the run_models_in, run_controller_in, and run_view_in
functions in compileapp.py to see how it is used.

ok, i see the source code for restricted but its use eludes me a bit. how
do i grab its executed processed output?

Got it. In that case, you can still use exec -- you probably want to wrap
it in a try/except. Here's what web2py does to execute all model,
controller, and view code (using the restricted() function in
restricted.py):
try:
if type(code) == types.CodeType:
ccode = code
yes, you're right, i should be more clear sorry. consider two text fields
in a table. one is called view and the other controller. the view has the
similar syntax we are used to, it is just stored in the table and row. and
the controller, i want to be able to allow myself to enter any type o

You can use template render
from gluon.template import render
html = "{{=name}} {{for x in range(10)}} Hello {{pass}}"
print render(content=html, context=dict(name="Bruno"))

ok, that is fine for simple code execution, but what of the more complex?
how does web2py execute all of that complex code we can embed within a
view? that is what i want to reproduce in my scheme.

You could use the Python exec command to execute the code, but if any of
the code comes from users, this is a very bad idea, as any malicious code
(or even a mere mistake) could do a lot of damage.

what using restricted or snapshot? would that be best and is it visible to
us normal web2py users?
