Overriding view declaration

[Thierry Florac]

Hi,

I created a view in a first package.

In another package (which is an optional extension of the first one), I need to create another view but with the same name and the same settings as the previous one but with another class which inherits from the first one.

By default, this raises a "pyramid.exceptions.ConfigurationConflictError" exception: Conflicting configuration actions!

So how can I "override" or "replace" a view declaration? Eventually, can I "unregister" a view declaration before registering the new one?

Best regards,

T. Florac

Basically if each view is registered from some call within a config.include'd function then if you establish an appropriate include-chain then you can override one call from the other.

def include_orig(config):

    config.scan('.orig_pkg')

def include_override(config):

    config.include(include_orig)

    config.scan('.override_pkg')

def main(...):

    # do not config.include(include_orig) here, instead include the override

    # otherwise they would be siblings and thus no clear chain

    config.include(include_override)

Now pyramid will have a chain that says specifically that the override is "closer" to your main than orig and thus its directives should win.
