You'd better use: from app1.models import Tax hints : - use CamelCase for classes - if app1 is in the same project, then you don't need to reference your project package - else, you'll have to add app1 to your pythonpath anyway - in both cases, you don't want to mention the project package itself - else it will break if you rename the 'myproject' directory, or try to reuse both apps in another project. Reading Python's FineManual(tm), specially the section about modules, packages and imports (in the tutorial) might be a good idea. > and then I: > > tax = models.ManyToManyField(tax) The results of this statement is that the name 'tax' is rebound to the models.ManyToManyField, sus shadowing the binding to the imported 'tax' class in the current class namespace. This may (or not) be the cause of your problem. You may want to search comp.lang.python's archive for posts about name bindings and namespaces in Python. > but it does nto work I can only second Steve's remark on this : "does not work" is almost the worst possible description of a problem. The useful thing to do is to: 1/ post minimal working code exhibiting the problem. 2/ explain clearly what you expected 3/ explain clearly what you got instead. If an exception is raised, please post the *whole* traceback.
