xml() error when BEAUTIFY globals()

[Lars]

Hi,

Everything is in the title : I try to have a BEAUTIFY look at copy.copy(globals()) and I get an xml error line 131 in html.py :

data is empty for : return data.xml()

Why can't we beautify globals() ?

Thank you

Maybe because .xml() method of various web2py class in gluon.html and is intent to be used over markup type languages not python language :

https://github.com/web2py/web2py/blob/master/gluon/html.py#L548

You can search for "def xml(" on this page to see all the differents implementation...

BEAUTIFY is not designed to take the entire global environment. The problem is that globals() includes all of the web2py HTML helper classes. Because BEAUTIFY is itself an HTML helper, it is serialized by recursively processing its components. The serialization process checks whether a given component has a callable "xml" attribute, and assuming such an attribute is an instance method, it attempts to call .xml(). The problem is the helper classes themselves do have a callable "xml" attribute, but it is not actually an instance method in that case (it is simply an attribute that belongs to the class itself) -- so calling it generates an exception.

You might try something like:

BEAUTIFY({k: v for k, v in globals().iteritems() if not hasattr(v, 'xml')})

But you're probably asking for trouble attempting to display the entire global environment.

Thanks Anthony, clearer than my explanation.

I went for something even simpler : I bypass BEAUTIFUL.. I just wanted a view with everything named :

def my_beautify(component):
    t = TABLE()
    if isinstance(component, dict):
        for k, v in component.iteritems():
            if v is None or isinstance(v, (bool, str)):
                t.append(TR([str(k), str(v), ' ']))
            else:
                t.append(TR([str(k), repr(v), str(dir(v))]))
    return t

Thanks to both of you ! :)
