Hi Andreas
I cant find a dedicated mailing list for django-rest-interface so I am
posting here for the time being. I am not quite sure if I am doing something
wrong or not, but I can happily GET and DELETE objects but I am having
trouble getting PUT and POST to work, and your examples don't really go into
details about how and where the REST client should PUT/POST too..
I have the following (simplified) model:
class Device(models.Model):
MacAddress = models.CharField(primary_key=True, maxlength=12)
SerialNo = models.CharField(maxlength=20)
def __str__(self):
return str(self.MacAddress)
def save(self):
super(Device, self).save() # Call the "real" save() method.
syslog.syslog('Saving data for: ' + self.MacAddress)
def delete(self):
syslog.syslog('Deleting: ' + self.MacAddress)
super(Device, self).delete() # Call the "real" delete() method.
def post(self):
syslog.syslog('Updating: ' + self.MacAddress)
super(Device, self).post() # Call the "real" post() method.
def put(self):
syslog.syslog('Adding: ' + self.MacAddress)
super(Device, self).put() # Call the "real" delete() method.
In urls.py I have:
device_resource = Collection(
queryset = Device.objects.all(),
permitted_methods = ('GET', 'POST', 'PUT', 'DELETE'),
receiver = XMLReceiver(),
responder = XMLResponder(paginate_by = 10)
)
urlpatterns = patterns('',
(r'^xml/device/(.*?)/?$', device_resource),
)
I have written a simple client using "restclient". You can see it works here
for GET and DELETE:
# ./atclient -g 000000000001
Processing MAC: 000000000001
<?xml version="1.0" encoding="utf-8"?>
<django-objects version="1.0"><object pk="000000000001"
model="provisioning.device"><field type="CharField"
name="SerialNo">000000000001</field></object></django-objects>
# ./atclient -d 000000000001
Deleting MAC: 000000000001
Object successfully deleted.
However trying to PUT a new object fails..
# ./atclient -a 000000000001
Adding MAC: 000000000001
<?xml version="1.0" encoding="utf-8"?>
<django-error><error-message>404 NOT
FOUND</error-message><status-code>404</status-code></django-error>
I see the PUT arriving at the web server:
[10/Sep/2007 15:03:50] "PUT /xml/device/ HTTP/1.1" 404 142
What exactly should I PUT, and to what url to make it add an object into the
database?
My client code currently looks like:
#! /usr/bin/python
import sys
import getopt
from restclient import GET, POST, PUT, DELETE
urlBase = 'http://127.0.0.1:8000/xml/device/'
def GetMac(macId):
response = GET(urlBase + macId.lower() + '/')
print response
def DelMac(macId):
response = DELETE(urlBase + macId.lower() + '/', async=False)
print response
def PostMac(macId):
response = POST(urlBase + macId.lower() + '/', async=False)
print response
def AirTiesPutMac(macId):
response = PUT(urlBase, async=False)
print response
if __name__ == '__main__':
def print_usage():
usage = "Usage: atclient -g MacAddress"
print usage; sys.exit()
try: opts, args = getopt.getopt(sys.argv[1:], 'a:d:g:u:')
except getopt.GetoptError: print_usage()
opts = dict(opts)
try: mode = opts.keys()[0]
except IndexError: print_usage()
if mode == '-g':
print "Getting MAC: " + opts['-g']
GetMac(opts['-g'])
elif mode == '-d':
print "Deleting MAC: " + opts['-d']
DelMac(opts['-d'])
elif mode == '-a':
print "Adding MAC: " + opts['-a']
PutMac(opts['-a'])
elif mode == '-u':
print "Updating MAC: " + opts['-u']
PostMac(opts['-u'])
I would appreciate any help you can give.
Thanks in Advance
