This articles covers how I was able to get the managed attributes from an object, and then get the public and managed attributes from an object. There used to be an __members__ method, but that has been depreciated according to http://docs.python.org/lib/specialattrs.html. Really, I hope there is a better way to do this, but I can’t seem to find it (let me know).
Quick Answer (for managed attributes only):
class dumb:
def dummy():
pass
def attributes(o):
print "object:", o
print "Initialized attribute values:"
step=0
for var in dir(o):
vartype=-1
exec("vartype = type(o."+str(var)+")")
if not(var in o.__dict__) and not(vartype == type( dumb.dummy)) and not("__" == var[:2]):
value = -30
exec("value = o."+str(dir(o)[step]))
print '%40s' % var +": "+ str(value)
step += 1
When changing websites, I was trying to use Apache’s RedirectMatch to send all documents from one domain to another domain. I used code that I found on other websites, but I found that it didn’t do what I wanted.
What I wanted was for a user to put in http://www.olddomain.com/a_file.html and be redirected to http://newdomain.com/a_file.html. I wanted it to do that for each file, and I didn’t want to specify a redirect for each file. I didn’t want to use mod_rewrite because I wanted to give the 301 redirect for Search Engine Optimization (SEO) reasons.
Quick Answer: use RedirectMatch permanent ^(.*)$ http://www.newdomain.com$1 in a .htaccess file in your old domain.
