Which credentials should I put in for Google App Engine BulkLoader at development server?

Question

I would like to ask which kind of credentials do I need to put on for importing data using the Google App Engine BulkLoader class

appcfg.py upload_data --config_file=models.py --filename=listcountries.csv --kind=CMSCountry --url=http://localhost:8178/remote_api vit/

And then it asks me for credentials:

Please enter login credentials for localhost

Here is an extraction of the content of the models.py, I use this listcountries.csv file

class CMSCountry(db.Model):
  sortorder = db.StringProperty()
  name = db.StringProperty(required=True)
  formalname = db.StringProperty()
  type = db.StringProperty()
  subtype = db.StringProperty()
  sovereignt = db.StringProperty()
  capital = db.StringProperty()
  currencycode = db.StringProperty()
  currencyname = db.StringProperty()
  telephonecode = db.StringProperty()
  lettercode = db.StringProperty()
  lettercode2 = db.StringProperty()
  number = db.StringProperty()
  countrycode = db.StringProperty()

class CMSCountryLoader(bulkloader.Loader):
  def __init__(self):
    bulkloader.Loader.__init__(self, 'CMSCountry',
                           [('sortorder', str),
                            ('name', str),
                            ('formalname', str),
                            ('type', str),
                            ('subtype', str),
                            ('sovereignt', str),
                            ('capital', str),
                            ('currencycode', str),
                            ('currencyname', str),
                            ('telephonecode', str),
                            ('lettercode', str),
                            ('lettercode2', str),
                            ('number', str),
                            ('countrycode', str)
                            ])
loaders = [CMSCountryLoader] 

Every tries to enter the email and password result in "Authentication Failed", so I could not import the data to the development server.

I don't think that I have any problem with my files neither my models because I have successfully uploaded the data to the appspot.com application.
So what should I put in for localhost credentials?
I also tried to use Eclipse with Pydev but I still got the same message :(
Here is the output:

Thank you!

EUREKA: I found the way to use the bulkloader.py tool without having to manually enter login credentials.

Here are the 2 steps:

---

Set your app.yaml file up. Example:

- url: /remote_api
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
  login: admin

You should put it BEFORE your - url: .* line in app.yaml, otherwise you will never access the /remote_api url.

Note that I've left the login: admin part, as removing it is a VERY BAD practice, since you might deploy that into production...

---

2 Launch this command (adapt it to your needs).

echo 'XX' | python2.5 ../google_appengine/bulkloader.py --dump --kind=NAMEOFMODEL --url=http://localhost:8080/remote_api --filename=FILENAME --app_id=APPID [email protected] --passin .

The trick is to use the combination of those 2 parameters:

• --email= (you can put whichever email address you want, I use [email protected])
• --passin

Specifying --email= will suppress the "enter credentials" prompt, and --passin will allow to read the password from stdin (that's where the echo 'XX' | comes into play!)

---

Enjoy!

P.S.: Don't forget to vote so that Google can provide an easier to use way to do that: Issue 2440.
