Ticket #800 (enhancement)

It would be nice if we could specify a default error template file.

Simply changing _cperror.py lines 276-280 CP_303:

    # Replace the default template with a custom one?
    error_page_file = cherrypy.request.error_page.get(code, '')
    if error_page_file:
        try:
            template = file(error_page_file, 'rb').read()

to this:

    # Replace the default template with a custom one?
    error_page_file = cherrypy.request.error_page.get(code, '')
    # If there's no custom one for that error number, is there a default?
    if not error_page_file:
        error_page_file = cherrypy.request.error_page.get(0, '')
    if error_page_file:
        try:
            # If it's a Python file, import everything from it.
            if error_page_file.split('.')[-1].lower() == 'py':
                exec('from %s import *' % error_page_file.split('.')[0])
                if 'kwargs_update' in locals():
                    kwargs.update(kwargs_update)
            # Otherwise, it's just a template in a file.
            else:
                template = file(error_page_file, 'rb').read()

Would change things:

• Defining a default error page handler (where N is the error page number):
  • 'error_page.N': 'error_config.py', or
  • 'error_page.N': 'error_config.foo'
• If N is 0, the error_page template will be used in place of the built-in default.
• Custom error pages are imported if they end in ".py". Otherwise they are read in.
• Imported pages can include a kwargs_udpate dictionary which will be included in the kwargs, if present.

This is completely backwards compatible.
