Re: Hello all & problem with server.py in SIMPLE

2009-11-10T15:57:00Z

Hi Nick,

Thanks for taking a look at it. I have tried patching both the server and client files but they dont seem to work. I attach the patched server file. Could you please send me the final python source for the server. I dont know exactly what went wrong.

All the best,
Javier

Hi All,

I am trying to follow the example programs for pyAMF but I get an error when trying to run the server.py module in the "shared object" example:

invalid syntax in line 56:

I have tried a couple of identing things but without success (I am not a pro in python unfortunately :-)

Thanks in advance:

Re: Make a wish: return Deferred from a WSGI request

2009-11-01T18:50:41Z

Hi,
I have surveyed the combination of the 3 super stars in the world of
Python: "Twisted+Django+pyAMF" for several days.
Because the Django lacks the ability to accept a returned Deferred,
That's the reason the Twisted comes into play.
For long running request, Deferred is a good solution.
Plus, I have no other choice if other funtion returns a Deferred.
Examples like the database connection pool of Twisted.
For all the requests (includes the requests to the pyAMF) which make
calls to the database via the connection pool,
There is no other way to get thing to go without the Deferred.

The perfect combination with current available solution is:

1) WSGI from Twisted.web2 to work with Django.
The reason is that WSGI of Twisted.web does not pass through POST request.
(I thougt that I have followed all the examples I can find from
google, Maybe I missed something)
Which destroy pratical usage of Django. Stuffs like the
administration, authentication of Django got broken.
WSGI from Twsited.web2 works fine.

2) WSGIGateway of pyAMF is great to work with twisted.web2. Except for
aceepting returned Deferred.

I can understand that web2 will be deprecated someday, But I think
there is only one step to the perfect of today.
The Deferred is not in the standard, that's why the Python/Twisted is so unique,
as well as pyAMF will be unique if it can handle the Deferred too.
No matter how, the pyAMF is great. I do appreciate the works you guys have done.

Re: Make a wish: return Deferred from a WSGI request

2009-11-01T13:19:23Z

Hi,

There is a couple reasons why this hasn't been implemented.

1) The WSGI Spec (at least 1.0) does not allow for asynchronous
responses.
2) Twisted supports WSGI out of the box - see twisted.web.wsgi
3) twisted.web2 is deprecated and will be removed at some point.

We did do some investigation into this - check http://pyamf.org/ticket/85
for more info.

Cheers,

Nick

Make a wish: return Deferred from a WSGI request

2009-11-01T04:49:47Z

Hi,

The TwistedGateway accept the expose method to return a Deferred instance.
But the TwistedGateway can not work with twisted.web2.
On the other hand. The WSGIGateway can work with twisted.web2,
but it does not accept the Deferred instance as the returned value.

Which one can I wish:
1) The TwistedGateway to work with web2
2) The WSGIGateway accept the Deferred instance as the returned value
just as the TwistedGateway does?
Or both :)

The reason to use with web2 is because that web2 works better with Django.
The parameters together with a "POST" request can be passed to the
Django through twisted.web2 wsgi implementation.
The twisted.web+Django only works for the "GET" request.

Any suggestion is welcomed.

How to catch the CannotSendRequest?

2009-10-15T00:08:30Z

Hi,

I have an application which utilize pyamf.remoting to
communicate between the server and client.

In the client side, sometimes, the httplib.CannotSendRequest
was thrown when calling the service methods.
(Mostly the server is too busy to handle the request).
My problem is that even I do this:
try:
maybe_failed_method()
except httplib.CannotSendRequest:
pass
the exception still can not be caught.
How can I handle about this?

Thanks in advance.

Hhmm… It's a nice screenshot, and he's got some cool ideas (ie,
storing session state), but I think (as we talked about on IRC), it's
infeasible to use. He uses Python comments to declare types… Which
means you've got to parse the .py files, instead of discovering them
with introspection. That'd lead to brittle code and generally makes me
very weary…

Yup, that's what I'm thinking of.

Well I know how to do all the .py introspection that will be required…
So I think we'll be able to work something out ;)

Re: Automatically generating ActionScript service classes?

2009-10-14T15:49:47Z

There is a big difference between a Service and a Business Delegate. Do you just want a service where a class:

- can be instantiated, and 1 method makes the call, with parameters, in the order they appear in the Python equivalent method

- dispatch a success/error event for the result

- publicly expose the result

If that's acceptable, I can see how this would be nice to not only auto-gen the services, but then write FlexUnit4 tests for them as well to ensure they actually work out of the box.

...the only thing I find hard about the above is parsing .py files. I could do it in AS3, but I suck in Python.

Anyway, I know a bunch of people have done this in Java & PHP; so I while I'd still build an abstraction layer on top of it, it would be a dope feature to have. In order of priority, I'd vote for easier Django model integration like Nick or whoever discussed awhile ago...

Hey,
Has anyone tinkered around with automatically generating ActionScript, given a PyAMF gateway?

I ask because it's sort of annoying to keep my services in sync… And I get jealous when I see the Java and PHP guys click "import web service" and magically get all sorts of helpful code generated for them.

Re: Automatically generating ActionScript service classes?

2009-10-14T15:48:25Z

Hi David!

The only project that I know of which attempts to do such a thing is http://code.google.com/p/pyamfcodegen/

I personally haven't used it but there is a nice screencast from the
author at http://basaratali.blogspot.com/2009/02/python-actinscript-code-gen.html
.

Hth,

Nick

Automatically generating ActionScript service classes?

2009-10-14T15:44:49Z

Hey,
Has anyone tinkered around with automatically generating ActionScript,
given a PyAMF gateway?

I ask because it's sort of annoying to keep my services in sync… And I
get jealous when I see the Java and PHP guys click "import web
service" and magically get all sorts of helpful code generated for them.

Re: Problem with "pyamf.Undefined"

2009-09-19T05:22:27Z

I had the same problem. My simple Django User worked, and any construct without a foreign key. Once I had to load some models, BUT not all their fields, it'd wig out.

On Sat, Sep 19, 2009 at 7:18 AM, Clay Zhong <zjclay@...> wrote:

Hi guys,

Sorry to bother again, but it seems another issue occur with the
pyamf.register_package.

I solved the pyamf.Undefined problem with select all related attributes
when sending response data to front site. But later I found it's not
what I want, because each request, I have to load model's all foreign
attributes even if it's useless. For example, I just want to get a
company basic info, but I have to use:

Company.object.select_related('city', 'city__province')

It seems fine with only one foreign key in company, but what will happen
if the model has many foreign keys and each of them also has other
foreign keys. The lazy loading was totally discarded, it should be a
serious performance issue. Is there any way I can work around? How about
write another plain object instead of using django model directly?

And there's another problem when I use django.contrib.auth.models.User
in my model:

from django.contrib.auth.models import User
class UserProfile(BaseModel):
user = models.ForeignKey(User, unique=True)
phone = models.CharField(max_length=50, blank=True)
cell_phone = models.CharField(max_length=50, blank=True)
title = models.CharField(max_length=100, blank=True)
login_times = models.IntegerField(default=0)
last_login_ip = models.IPAddressField(blank=True)
history = models.XMLField(blank=True)
company = models.ForeignKey(Company)

Here is the traceback:

Re: Problem with "pyamf.Undefined"

2009-09-19T04:18:45Z

Hi guys,

Sorry to bother again, but it seems another issue occur with the
pyamf.register_package.

I solved the pyamf.Undefined problem with select all related attributes
when sending response data to front site. But later I found it's not
what I want, because each request, I have to load model's all foreign
attributes even if it's useless. For example, I just want to get a
company basic info, but I have to use:

Company.object.select_related('city', 'city__province')

It seems fine with only one foreign key in company, but what will happen
if the model has many foreign keys and each of them also has other
foreign keys. The lazy loading was totally discarded, it should be a
serious performance issue. Is there any way I can work around? How about
write another plain object instead of using django model directly?

And there's another problem when I use django.contrib.auth.models.User
in my model:

from django.contrib.auth.models import User
class UserProfile(BaseModel):
user = models.ForeignKey(User, unique=True)
phone = models.CharField(max_length=50, blank=True)
cell_phone = models.CharField(max_length=50, blank=True)
title = models.CharField(max_length=100, blank=True)
login_times = models.IntegerField(default=0)
last_login_ip = models.IPAddressField(blank=True)
history = models.XMLField(blank=True)
company = models.ForeignKey(Company)

Here is the traceback:

Re: A decoding problem with diango

2009-09-16T10:03:37Z

I have done some quick investigation into defaults in Django models, for primitive types:

Given a model:

class TestModel(models.Model):

char = models.CharField(max_length=100)

char_blank = models.CharField(max_length=100, blank=True)

char_null = models.CharField(max_length=100, null=True)

char_blank_null = models.CharField(max_length=100, null=True, blank=True)

char_default = models.CharField(max_length=100, default='foo')

char_default_blank = models.CharField(max_length=100, default='foo', blank=True)

char_default_blank_null = models.CharField(max_length=100, default='foo', blank=True, null=True)

boolean = models.BooleanField()

boolean_blank = models.BooleanField(blank=True)

boolean_default = models.BooleanField(default=False)

boolean_default_blank = models.BooleanField(default=False, blank=True)

null_boolean = models.NullBooleanField()

null_boolean_blank = models.NullBooleanField(blank=True)

null_boolean_default = models.NullBooleanField(default=False)

null_boolean_default_blank = models.NullBooleanField(default=False, blank=True)

integer = models.IntegerField()

integer_blank = models.IntegerField(blank=True)

integer_null = models.IntegerField(null=True)

integer_blank_null = models.IntegerField(null=True, blank=True)

integer_default = models.IntegerField(default=0)

integer_default_blank = models.IntegerField(default=0, blank=True)

integer_default_blank_null = models.IntegerField(default=0, blank=True, null=True)

decimal = models.DecimalField(max_digits=5, decimal_places=2)

decimal_blank = models.DecimalField(max_digits=5, decimal_places=2, blank=True)

decimal_null = models.DecimalField(max_digits=5, decimal_places=2, null=True)

decimal_blank_null = models.DecimalField(max_digits=5, decimal_places=2, null=True, blank=True)

decimal_default = models.DecimalField(max_digits=5, decimal_places=2, default=0.1)

decimal_default_blank = models.DecimalField(max_digits=5, decimal_places=2, default=0.1, blank=True)

decimal_default_blank_null = models.DecimalField(max_digits=5, decimal_places=2, default=0.1, blank=True, null=True)

Creating an instance:

x =TestModel()

print x.__dict__

gives:

{'boolean': False,

'boolean_blank': False,

'boolean_default': False,

'boolean_default_blank': False,

'char': '',

'char_blank': '',

'char_blank_null': None,

'char_default': u'foo',

'char_default_blank': u'foo',

'char_default_blank_null': u'foo',

'char_null': None,

'decimal': None,

'decimal_blank': None,

'decimal_blank_null': None,

'decimal_default': 0.10000000000000001,

'decimal_default_blank': 0.10000000000000001,

'decimal_default_blank_null': 0.10000000000000001,

'decimal_null': None,

'id': None,

'integer': None,

'integer_blank': None,

'integer_blank_null': None,

'integer_default': 0,

'integer_default_blank': 0,

'integer_default_blank_null': 0,

'integer_null': None,

'null_boolean': None,

'null_boolean_blank': None,

'null_boolean_default': False,

'null_boolean_default_blank': False}

Which is what PyAMF is going to use to encode the instance. It all looks pretty sane to me.

It appears that AS3 (correct me if I'm wrong) that uint/int/Number will support 'undefined' so the Django ORM adapter would have to check for 'None' and convert accordingly. Is this sensible?

Not sure if there are any other cases to check for?

Cheers,

Nick

String default so null, which is fine. But int, uint, and Number are NaN... what would the data default to?

It wouldn't be a huge deal, but Django doesn't really give you, at least in my n00b experience, fine grained detail over WHAT it was expecting for a value; the error is like totally unrelated, at least at first glance. There seems nothing wrong with Django requiring something for what it specifically is coded to require for... but that doesn't really make things very agile. If you could coerce it to the nearest default value, by default, that'd be smokin' hawt.

This was intentional to force the Flex client to send a complete model
instance. This 'feature' is run into time and again with lots of
questions on stackoverflow and even workarounds being created like in
Jesse's mail. I can see now that this functionality was a mistake and
it makes sense to not require any static properties on models for all
ORM's (Django, SQLAlchemy, GAE etc.)

I think even the 'required' fields should not be required by PyAMF and
let the relevant ORM handle attributes. What do you think?

I made Blank and Null to true in my Model to allow my Flex VO's to be slack; meaning if no data... then no data. You still get into strange situations where a String is null vs. "", but makes it a ton easier to work with. If not, you spend a lot of data validation on your Flex side. This is ok if you have the time, but if not, Blank + Null to git-r-done.

Hi Thijs,

Here is the traceback:

It works out by Ricardo's way, I change the select_related to Company.objects.select_related('city', 'city__province').all(), it works fine.
Thanks all you guys.

Does this only occur when a request received, rather than responding
to the request?

A full stacktrace would be useful here and any logs/logging that you
may have.

Thanks!
