Zope将URL映射到视图

Question

I am debugging large Zope application, and no experience with Zope Framework. I am trying to find code which is called requests.

All I know, that pages are generated by calls to instances of Products.Five.browser.BrowserView , but how to know which of them will be called? How zope maps URLs to views?

Answer 1

I think you want to know which View is called for a specific URL. In all instances of Zope applications I ever came across there are files named configure.zcml in the main folder of the application, in which you can start to look how the parts are fitted together.

If it is not apparent where to look for, you can start in one of the following places:

• in the instance location ( INSTANCE_HOME ) of your application, there is possibly a etc/package-includes/ path, with one ore more .zcml-files in it ("config slugs") which list packages where zope looks for configure.zcml -files

• all directories below $INSTANCE_HOME/Products are searched for configure.zcml -files

There you look for sections like this::

<browser:page
    for="*"
    permission="zope2.View"
    name="this_is_an_url_name"
    class="package_name.module_name.ClassName"
    />

which maps an URL to an View.

Also, heads up :-) Zope has some learning curve, but it is powerful.
