I am try create a new Module. I define in the first class some columns(type=char) in these are some field names and I want to display these enteries as fields in another class.

But I don't really understand some parts of the following function.

def fields_view_get(self, cr, uid, view_id=None, view_type='form', context=None, toolbar=False,submenu=False):
    result = super(categories, self).fields_view_get(cr, uid, view_id, view_type, context, toolbar,submenu)

What does the next line do? Can I specify here the classes from where the function will read the fields?

school_obj = self.pool.get('sim.categories')
result['arch']
return result

How can I tell the function to get the fields from a specific class and how can I display the result in a form for debugging and testing?

Can you give me a Module name in which a dynamic field view was already realized? I think in post_return from v6 is something that I want. Is this code compatible to v7 or give it a better solution?
