mò $á¸Ec@s d„Zdfd„ƒYZdS(cCsdS(s7 Add an external method to an 'ObjectManager'. In addition to the standard object-creation arguments, 'id' and title, the following arguments are defined: function -- The name of the python function. This can be a an ordinary Python function, or a bound method. module -- The name of the file containing the function definition. The module normally resides in the 'Extensions' directory, however, the file name may have a prefix of 'product.', indicating that it should be found in a product directory. For example, if the module is: 'ACMEWidgets.foo', then an attempt will first be made to use the file 'lib/python/Products/ACMEWidgets/Extensions/foo.py'. If this failes, then the file 'Extensions/ACMEWidgets.foo.py' will be used.

The function is defined in an external file. This file is treated like a module, but is not a module. It is not imported directly, but is rather read and evaluated. The file must reside in the 'Extensions' subdirectory of the Zope installation, or in an 'Extensions' subdirectory of a product directory. Due to the way ExternalMethods are loaded, it is not *currently* possible to import Python modules that reside in the 'Extensions' directory. It is possible to import modules found in the 'lib/python' directory of the Zope installation, or in packages that are in the 'lib/python' directory. cCsdS(s¦ Change the External Method. See the description of manage_addExternalMethod for a description of the arguments 'module' and 'function'. Note that calling 'manage_edit' causes the "module" to be effectively reloaded. This is useful during debugging to see the effects of changes, but can lead to problems of functions rely on shared global data. N((RRRtREQUEST((Rt manage_edit@s cOsdS(s¦ Call the External Method. Calling an External Method is roughly equivalent to calling the original actual function from Python. Positional and keyword parameters can be passed as usual. Note however that unlike the case of a normal Python method, the "self" argument must be passed explicitly. An exception to this rule is made if: - The supplied number of arguments is one less than the required number of arguments, and - The name of the function's first argument is 'self'. In this case, the URL parent of the object is supplied as the first argument. N((targstkw((Rt__call__Os(t__name__t __module__t__doc__Rt__constructor__tNoneRR (((RR+s  N(RR(RR((Rt?s
