Here is the code, if someone is interested in it :)

def return_noperm_function():
  return {"state": "noperm"}

def check_login(ctx):
  if not function_for_checking_login_and_password():
    ctx.descriptor.function = return_noperm_function
    ctx.in_object = ()

tests.event_manager.add_listener("method_call", check_login)


Don't forget to somehow bypass other events when returning 'noperm' (for example 'method_return_object').

Are you forced to use "SOAPpy" (which I do not know much about)?

If not, you may give "suds" a try. It is a very easy to use
SOAP client with quite good adherence to the respective standards.

If your WSDL calls for XML request documents like the above, "suds"
would give you something similar (you would in addition get
a SOAP envelope with namespace declarations -- as required by the standards).

Message-ID: <CAJNfEdwtZuL+3B4Q3R_HF1rU6cLuyNJoFQ9Swz2mwEcNaaRm_A@mail.gmail.com>

Hello

I'm new to soaplib and web services (which means possible stupid
question ahead ;-) ).

I'm having a problem with soaplib. I've the following function
provided by a web service :

@soap(Integer, Integer, _returns=Integer)
def test(self, n1, n2):
? ? return n1 + n2

The corresponding declaration for the datatypes in the generated WSDL file is

<xs:complexType name="test">
? <xs:sequence>
? ? <xs:element name="n1" type="xs:integer" minOccurs="0" nillable="true"/>
? ? <xs:element name="n2" type="xs:integer" minOccurs="0" nillable="true"/>
? </xs:sequence>
</xs:complexType>
<xs:complexType> name="testResponse">
? <xs:sequence>
? ? <xs:element name="testResult" type="xs:integer" minOccurs="0"
nillable="true"/>
? </xs:sequence>
</xs:complexType>

When I use some IDE (Visual Studio, PowerBuilder) to generate code
from that WSDL file, whatever the IDE, it generates two classes for
test and for testResponse, whose attributes are Strings.

Does anyone know if I can tweak my Python declaration so that I avoid
complexType and obtain real Integer datatype on my client side ?


Thanks

hi,

you're looking for non-wrapped variables. rpclib has the interface in
place to support that, but it's not tested so i'm pretty sure it doesn't
work. i've also looked at soaplib source and don't think soaplib has
support for that at all.

but then, maybe your client should be able to handle this? I know suds
employs some heuristics to detect wrapped vs non-wrapped wsdl documents
and acts accordingly.

hth,

you have the wsgi environment at ctx.transport.req_env.

look at:

WsgiMethodContext documentation at:
http://arskom.github.com/rpclib/reference/server.html

you need to override call_wrapper in either Application or ServiceBase
and do your own exception handling there.

e.g.

class MyException(Fault):
    pass

@classmethod
def call_wrapper(cls,ctx):
    try:
        ServiceBase.call_wrapper(ctx)
    except MyException,e:
        logger.exception(e)
        raise
    except Exception,e:
        raise MyException("Server", "Unknown error")

e.g.

# changed the place of logger.exception where logger = \
# logging.getLogger(__name__)

class MyException(Fault):
    pass

that's how i do what you say in my production deployments. i don't think
that's difficult to do.

see:

Message-ID: <CAHheN2mQSHR_6hm_y-q61F-gv=PeC1vzAGUdP-Tniajq6Lb01A@mail.gmail.com>

Hello Everybody,

I have been using soaplib since a few weeks. One thing caught my eye. Its
the "Date" and "DateTime" data types. I wanted to have a customized
representation/format of the Date object when the xml tree is generated. The
default one is YYYY-MM-DD. But what if I wanted to have YYYY/MM/DD or
DD-MM-YYYY ? I have tried to look for a way I can do it with the existing
soaplib API. Unfortunately I was not able to figure out. Can you please
guide me ? If I know the trick, I can implement it and will send a
pull-request for your review. Please help.

Here is sample code:

from lxml import etree
from soaplib.core.model.primitive import String, Date
from soaplib.core.model.clazz import ClassModel
from soaplib.core.util.model_utils import ClassModelConverter
from datetime import datetime

class FormattedDate(Date):
      '''This is supposed to used for a customized Date display'''
      pass

class Employee(ClassModel):
**      roll = String
      dob = FormattedDate(nillable=False, min_occurs=1, max_occurs=1,
doc='Date of Birth')

emp = Employee()
emp.roll = '001'
emp.dob = datetime.date(datetime.now())
conv = ClassModelConverter(emp)
conv.include_parent = False
conv.include_ns = True
print conv.to_xml()

PS: I haven't tried rpclib <https://github.com/arskom/rpclib>, but I guess
the customizations which I want to achieve for soaplib, might be the same
for rpclib also. If not, can you please clarify ?
Regards,
Nandakishore

Hello Nanda,

The current date format in both soaplib and rpclib respects the SOAP
standard which in turn respects relavant iso standard on encoding
date/time information. So i do not suggest you to alter the way the Date
and DateTime objects are serialized.

That said, you can have a look at:

https://github.com/arskom/rpclib/blob/master/src/rpclib/model/primitive.py#L343

to see how the date object works in rpclib. copy that class, change its
name, alter its from_string and to_string methods to your liking and
voila, you have your own date class.

it's almost the same for soaplib, just a bit more inconsistent. have a
look at:
https://github.com/soaplib/soaplib/blob/master/src/soaplib/core/model/primitive.py#L196

you should alter to_parent_element and from_string methods in a custom
model class that inherits from SimpleType.

hope that helps

Hi,

I'm having problems with a Date value with this context :

class UserUpdate(TableModel, DeclarativeBase):
    __namespace__ = nameSpace
    __tablename__ = 'user_update'

    user_id = Column(sqlalchemy.Integer)
    date = Column(sqlalchemy.Date, nullable=True)
    heure = Column(sqlalchemy.Time)


    @rpc(Int(min_occurs=1, max_occurs=1),
        _returns=Iterable(UserUpdate))
    def tpz_getUserUpdate(ctx, user_id):
        updates =
ctx.udc.session.query(UserUpdate).filter(UserUpdate.user_id ==
user_id).all()
        return updates

I'm using a MySQL database where where those "date" and "heure" column
are respectively DATE and TIME types.

Thus, when calling the WS method above, I get the following error message :
[...]
  File "C:\Python27\lib\site-packages\rpclib-2.4.4_beta-py2.7.egg\rpclib\model\primitive.py",
line 443, in to_string
    if value.days < 0:
AttributeError: 'datetime.time' object has no attribute 'days'

Any ideas how I can fix that ? Thanks

Message-ID: <20111025131547.3918F733@pobox.sk>


Hi,

i'm having problems when returning non-unicode strings which contains unicode characters (i have strings in utf-8 but they are not python unicode):

ValueError: All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control characters

Everything works fine when i convert strings to unicode but i cannot do this with all strings, i don't consider nice and clear to convert all strings just before returning them (i have most of them from MySQL returned by module python-mysql). Is there any way how could rpclib convert this for me before lxml parsing ? Everything is in UTF-8 so it shouldn't be a problem. Thank you.

don't be so sure ;) rpclib is still beta software.

see my comments in the issue tracker.

heh :)

And I thought there must be a good reason there was a Date primitive,
but no Time.  I suppose I should have asked.

utf8 is just one way of encoding unicode data, and i don't want to have
hard-coded encodings in rpclib. when I had to deal with a similar
problem recently, I chose to tweak my db connection (psycopg) to always
return unicode data. i now have peace of mind :) i suggest you to do the
same.

this of course may not suit your needs. there's a hidden _String type in
rpclib.model.primitive in my personal fork. does it work for you? you
can set its encoding to whatever you want using
_String(encoding='whatever').

I can't decide whether it should be left as String or moved to binary
module and renamed to Bytes.

does that help?

yes virtualenv would help, i would not suggest that to a newbie.

here's what you should do:

1) first clone my rpclib repository somewhere. git clone
git://github.com/plq/rpclib.git
2) in your server's main module, right after you import rpclib, add this:

print rpclib.__file__

note the shown file path.

3) in your server's main module, add those to top, before importing
anything rpclib-related:

import sys
sys.path.append('/path/to/the/cloned/rpclib/repo/src')
# (where rpclib is checked out to: /path/to/the/cloned/rpclib/repo)

again, use 'print rpclib.__file__' and note that the file name has changed.

you can switch back to the stable(!) rpclib by commenting the
sys.path.append line.

let me know how this works.

best regards,
burak

Hi Burak !

The dev repo you pointed out works fine as far as these sqlalchmy.Date
and sqlalchemy.Time are concerned :-)
Thanks a lot for the patch !  Do you have some visibility about a release date ?

PS: I think I've found another bug, producing an infinite loop. I'm
going to file a new issue on github about this.

Thanks again

I'm waiting for the fix to the regression introduced in
https://github.com/arskom/rpclib/issues/97 . you can track its progress
at https://github.com/arskom/rpclib/issues/106. i plan to wait a bit
more -- if the author does not show up, i'll release rpclib withot that
patch.

I have finally decided to convert _everything_ to unicode in my code and set all modules to return unicode too (in MySQLdb module, this can be set when doing connection via 'use_unicode' argument).

thnx.
