Create activities for an user with Stream-Framework

I'm trying to setup stream-framework the one here not the newer getstream. I've setup the Redis server and the environment properly, the issue I'm facing is in creating the activities for a user.
I've been trying to create activities, following the documentation to add an activity but it gives me an error message as follows:
...
File "/Users/.../stream_framework/activity.py", line 110, in serialization_id
if self.object_id >= 10 ** 10 or self.verb.id >= 10 ** 3:
AttributeError: 'int' object has no attribute 'id'
Here is the code
from stream_framework.activity import Activity
from stream_framework.feeds.redis import RedisFeed
class PinFeed(RedisFeed):
key_format = 'feed:normal:%(user_id)s'
class UserPinFeed(PinFeed):
key_format = 'feed:user:%(user_id)s'
feed = UserPinFeed(13)
print(feed)
activity = Activity(
actor=13, # Thierry's user id
verb=1, # The id associated with the Pin verb
object=1, # The id of the newly created Pin object
)
feed.add(activity) # Error at this line
I think there is something missing in the documentation or maybe I'm doing something wrong. I'll be very grateful if anyone helps me get the stream framework working properly.

The documentation is inconsistent. The verb you pass to the activity should be (an instance of?*) a subclass of stream_framework.verbs.base.Verb. Check out this documentation page on custom verbs and the tests for this class.
The following should fix the error you posted:
from stream_framework.activity import Activity
from stream_framework.feeds.redis import RedisFeed
from stream_framework.verbs import register
from stream_framework.verbs.base import Verb
class PinFeed(RedisFeed):
key_format = 'feed:normal:%(user_id)s'
class UserPinFeed(PinFeed):
key_format = 'feed:user:%(user_id)s'
class Pin(Verb):
id = 5
infinitive = 'pin'
past_tense = 'pinned'
register(Pin)
feed = UserPinFeed(13)
activity = Activity(
actor=13,
verb=Pin,
object=1,
)
feed.add(activity)
I quickly looked over the code for Activity and it looks like passing ints for actor and object should work. However, it is possible that these parameters are also outdated in the documentation.
* The tests pass in classes as verb. However, the Verb base class has the methods serialize and __str__ that can only be meaningfully invoked if you have an object of this class. So I'm still unsure which is required here. It seems like in the current state, the framework never calls these methods, so classes still work, but I feel like the author originally intended to pass instances.

With the help of great answer by #He3lixxx, I was able to solve it partially. As the package is no more maintained, the package installs the latest Redis client for python which was creating too many issues so by installation redis-2.10.5 if using stream-framework-1.3.7, should fix the issue.
I would also like to add a complete guide to properly add activity to a user feed.
Key points:
If you are not using feed manager, then make sure to first insert the activity before you add it to the user with feed.insert_activity(activity) method.
In case of getting feeds with feed[:] throws an error something like below:
File "/Users/.../stream_framework/activity.py", line 44, in get_hydrated
activity = activities[int(self.serialization_id)]
KeyError: 16223026351730000000001005L
then you need to clear data for that user using the key format for it in my case the key is feed:user:13 for user 13, delete it with DEL feed:user:13, In case if that doesn't fix the issue then you can FLUSHALL which will delete everything from Redis.
Sample code:
from stream_framework.activity import Activity
from stream_framework.feeds.redis import RedisFeed
from stream_framework.verbs import register
from stream_framework.verbs.base import Verb
class PinFeed(RedisFeed):
key_format = 'feed:normal:%(user_id)s'
class UserPinFeed(PinFeed):
key_format = 'feed:user:%(user_id)s'
class Pin(Verb):
id = 5
infinitive = 'pin'
past_tense = 'pinned'
register(Pin)
feed = UserPinFeed(13)
print(feed[:])
activity = Activity(
actor=13,
verb=Pin,
object=1)
feed.insert_activity(activity)
activity_id = feed.add(activity)
print(activity_id)
print(feed[:])

pyral accessing customfield .attributes values from CA Agile Central

I'm super new in development in general. I'm currently building a webapp that get data from Rally/CA Agile Central and put them in a neat table.
My code:
response = rally.get('UserStory', fetch = True, query=query_criteria)
response_defect = rally.get('Defect', fetch = True, query=query_criteria)
story_list = []
if not response.errors:
for story in response:
#print (story.details())
a_story={}
#a_story['State'] = story.State.Name #if story.State else "Backlog"
a_story['State']=story.BusOpsKanban if story.BusOpsKanban else "unassigned"
#a_story['Status']=Story.Status if story.Status else "unassigned"
a_story['id'] = story.FormattedID
a_story['name'] = story.Name
a_story['Opened']=(datetime.strptime(story.CreationDate, '%Y-%m-%dT%H:%M:%S.%fZ').strftime('%Y-%d-%b'))
a_story['Requester']= story.Owner.Name if story.Owner else "unassigned"
a_story['Blocked']= story.Blocked
a_story['Service']=story.c_ServiceNowID
My issue is to get access to the value of the linkid of my customfield (c_ServiceNowID).
When I run a Dict = I see that I have LinkID attributes but when I type
story.c_ServiceNowID.LinkID, I receive an error message telling me there is no such attributes.... How do I access this value using python ?
Thank you

According to the documentation at http://pyral.readthedocs.io/en/latest/overview.html#custom-fields, pyral allows you to reference the field without the c_ prefix
Most Artifact types in Rally can be augmented with custom fields. As of Rally WSAPI v2.0, the ElementName for a custom field is prefixed with ‘c_’. The pyral toolkit allows you to reference these fields without having to use the ‘c_’ prefix. For example, if your custom field has a DisplayName of ‘Burnt Offerings Index’ you can use the String of ‘BurntOfferingsIndex’ in a fetch clause or a query clause or refer to the field directly on an artifact as artifact.BurntOfferingsIndex.

I think what you have should work, unless the ServiceNowID is empty. In that case there will not be a LinkID or DisplayString available on the ServiceNowID object.
If you update your code to check to make sure the Attribute is there, does it work?
if hasattr(story.c_ServiceNowID, 'LinkID'):
a_story['Service']=story.c_ServiceNowID.DisplayString
a_story['Link']=story.c_ServiceNowID.LinkID

Google app engine - Order listed item

I need your help to order listed item.
I am trying to make apps that can send message to his/her friends ( just like social feeds ). After watching Bret Slatkin talk about create microblogging here's my code:
class Message(ndb.Model):
content = ndb.TextProperty()
created = ndb.DateTimeProperty(auto_now=True)
class MessageIndex(ndb.Model):
receivers = ndb.StringProperty(repeated=True)
class BlogPage(Handler):
def get(self):
if self.request.cookies.get("name"):
user_loggedin = self.request.cookies.get("name")
else:
user_loggedin = None
receive = MessageIndex.query(MessageIndex.receivers == user_loggedin)
receive = receive.fetch()
message_key = [int(r.key.parent().id()) for r in receive]
messages = [Message.get_by_id(int(m)) for m in message_key]
for message in messages:
self.write(message)
The first I do a query to get all message that has my name in the receivers. MessageIndex is child of Message, then I can get key of all message that I receive. And the last is I iter get_by_id using list of message key that I get.
This works fine, but I want to filter each message by its created datetime and thats the problem. The final output is listed item, which cant be ordered using .order or .filter
Maybe some of you can light me up.

You can use the message keys in an 'IN' clause in the Message query. Note that you will need to use the parent() key value, not the id() in this case.
eg:
# dtStart, dtEnd are datetime values
message_keys = [r.key.parent() for r in receive]
query = Message.query(Message._key.IN(message_keys), Message.created>dtStart, Message.created<dtEnd)
query = query.order(Message.created) # or -Message.created for desc
messages = query.fetch()
I am unsure if you wish to simply order by the Message created date, or whether you wish to filter using the date. Both options are catered for above.

Magento product creation through SOAP v2

I’m implementing a service in Python that interacts with Magento through SOAP v2. So far, I’m able to get the product list doing something like this:
import suds
from suds.client import Client
wsdl_file = 'http://server/api/v2_soap?wsdl=1'
user = 'user'
password = 'password'
client = Client(wsdl_file) # load the wsdl file
session = client.service.login(user, password) # login and create a session
client.service.catalogProductList(session)
However, I’m not able to create a product, as I don’t really know what data I should send and how to send it. I know the method I have to use is catalogProductCreate, but the PHP examples shown here don’t really help me.
Any input would be appreciated.
Thank you in advance.

You are there already. I think your issue is not able to translate the PHP array of arguments to be passed into Python Key Value pairs. If thats the case this will help you a bit. As well as need to set the attribute set using catalogProductAttributeSetList before you create the product
attributeSets = client.service.catalogProductAttributeSetList(session)
#print attributeSets
# Not very sure how to get the current element from the attributeSets array. hope the below code will work
attributeSet = attributeSets[0]
product_details = [{'name':'Your Product Name'},{'description':'Product description'},{'short_description':'Product short description'},{'weight':'10'},{ 'status':'1'},{'url_key':'product-url-key'},{'url_path':'product-url-path'},{'visibility' :4},{'price':100},{'tax_class_id':1},{'categories': [2]},{'websites': [1]}]
client.service.catalogProductCreate(session , 'simple', attributeSet.set_id, 'your_product_sku',product_details)

suds.TypeNotFound: Type not found: 'productData'
Because the productData format is not right. You may want to change from
product_details = [{'name':'Your Product Name'},{'description':'Product description'}, {'short_description':'Product short description'},{'weight':'10'},{ 'status':'1'},{'url_key':'product-url-key'},{'url_path':'product-url-path'},{'visibility' :4},{'price':100},{'tax_class_id':1},{'categories': [2]},{'websites': [1]}]
to
product_details = {'name':'Your Product Name','description':'Product description', 'short_description':'Product short description','weight':'10', 'status':'1','url_key':'product-url-key','url_path':'product-url-path','visibility' :4,'price':100,'tax_class_id':1,'categories': [2],'websites': [1]}
It works for me.

Google Analytics and Python

I'm brand new at Python and I'm trying to write an extension to an app that imports GA information and parses it into MySQL. There is a shamfully sparse amount of infomation on the topic. The Google Docs only seem to have examples in JS and Java...
...I have gotten to the point where my user can authenticate into GA using SubAuth. That code is here:
import gdata.service
import gdata.analytics
from django import http
from django import shortcuts
from django.shortcuts import render_to_response
def authorize(request):
next = 'http://localhost:8000/authconfirm'
scope = 'https://www.google.com/analytics/feeds'
secure = False # set secure=True to request secure AuthSub tokens
session = False
auth_sub_url = gdata.service.GenerateAuthSubRequestUrl(next, scope, secure=secure, session=session)
return http.HttpResponseRedirect(auth_sub_url)
So, step next is getting at the data. I have found this library: (beware, UI is offensive) http://gdata-python-client.googlecode.com/svn/trunk/pydocs/gdata.analytics.html
However, I have found it difficult to navigate. It seems like I should be gdata.analytics.AnalyticsDataEntry.getDataEntry(), but I'm not sure what it is asking me to pass it.
I would love a push in the right direction. I feel I've exhausted google looking for a working example.
Thank you!!
EDIT: I have gotten farther, but my problem still isn't solved. The below method returns data (I believe).... the error I get is: "'str' object has no attribute '_BecomeChildElement'" I believe I am returning a feed? However, I don't know how to drill into it. Is there a way for me to inspect this object?
def auth_confirm(request):
gdata_service = gdata.service.GDataService('iSample_acctSample_v1.0')
feedUri='https://www.google.com/analytics/feeds/accounts/default?max-results=50'
# request feed
feed = gdata.analytics.AnalyticsDataFeed(feedUri)
print str(feed)

Maybe this post can help out. Seems like there are not Analytics specific bindings yet, so you are working with the generic gdata.

I've been using GA for a little over a year now and since about April 2009, i have used python bindings supplied in a package called python-googleanalytics by Clint Ecker et al. So far, it works quite well.
Here's where to get it: http://github.com/clintecker/python-googleanalytics.
Install it the usual way.
To use it: First, so that you don't have to manually pass in your login credentials each time you access the API, put them in a config file like so:
[Credentials]
google_account_email = youraccount#gmail.com
google_account_password = yourpassword
Name this file '.pythongoogleanalytics' and put it in your home directory.
And from an interactive prompt type:
from googleanalytics import Connection
import datetime
connection = Connection() # pass in id & pw as strings **if** not in config file
account = connection.get_account(<*your GA profile ID goes here*>)
start_date = datetime.date(2009, 12, 01)
end_data = datetime.date(2009, 12, 13)
# account object does the work, specify what data you want w/
# 'metrics' & 'dimensions'; see 'USAGE.md' file for examples
account.get_data(start_date=start_date, end_date=end_date, metrics=['visits'])
The 'get_account' method will return a python list (in above instance, bound to the variable 'account'), which contains your data.

You need 3 files within the app. client_secrets.json, analytics.dat and google_auth.py.
Create a module Query.py within the app:
class Query(object):
def __init__(self, startdate, enddate, filter, metrics):
self.startdate = startdate.strftime('%Y-%m-%d')
self.enddate = enddate.strftime('%Y-%m-%d')
self.filter = "ga:medium=" + filter
self.metrics = metrics
Example models.py: #has the following function
import google_auth
service = googleauth.initialize_service()
def total_visit(self):
object = AnalyticsData.objects.get(utm_source=self.utm_source)
trial = Query(object.date.startdate, object.date.enddate, object.utm_source, ga:sessions")
result = service.data().ga().get(ids = 'ga:<your-profile-id>', start_date = trial.startdate, end_date = trial.enddate, filters= trial.filter, metrics = trial.metrics).execute()
total_visit = result.get('rows')
<yr save command, ColumnName.object.create(data=total_visit) goes here>
