Load objects using __import__

[MindClass]

I load objects from a file (to django framework _but it's a python
question_).

1) Before I used this
from project.I18n.mo dels import *

And to load the object
c1 = Country(name="A fghanistan")

But the problem is that there is to edit 'project' manually.

2) So I setup the environment and import the module:
project_directo ry = os.path.abspath ('')
project_name = os.path.basenam e(project_direc tory)
os.environ['DJANGO_SETTING S_MODULE'] = "%s.setting s" % project_name
sys.path.append (os.path.dirnam e(project_direc tory))
module = __import__('%s. I18n.models' % (project_name), {}, {},
[''])
sys.path.pop()

It's all correct until here and to checking it I run:
print i18n_module
<module 'project.I18n.m odels' from
'/home/lala/django/project/I18n/models.pyc'>

print i18n_module.Cou ntry
<class 'project.I18n.m odels.Country'>

But when I load the object I get
SyntaxError: invalid syntax

c1 = <module 'project.I18n.m odels' from
'/home/lala/django/project/I18n/models.pyc'>.Co untry(name="Afg hanistan")

Any idea?

It looks like you're running generated code somewhere, but passing the
module itself rather than the name of the module to the code generator
by mistake. Perhaps you're execing some code that you pass the module
name to? Something like this?

exec 'c1 = %s.Country(name ="Afgahanstan") ' % module_name

You seem to be erroneously using the module itself, not the module
name.

That's about all I can help without more information.


P.S. if you are doing that, consider using getattr instead of exec.

c1 = getattr(module, Country)(name=" Afgansitan")

Re: Load objects using __import__

Indeed before reading your message I solved it doing:

model_name = Country
mod = eval('i18n_modu le.%s' % model_name)
c1 = mod(name="Afgha nistan")
exec c1

but I'll use getattr as you say. Thanks
