I have a simple pinterest clone app built and have a basic activity stream setup.
The activity stream only records when a new image is created, when an image is liked, when a new user is created, or when a followed user follows another user.
What I would like to implement and do not know how is accumulation, for example if 2 or more user like a certain image, I would prefer the activity stream to say:
"User 1 and User 2 like image"
Can any one help me achieve this?
The Action models in django-activity-stream could be helpful.
For example, when an Actor performs an action, you could look up if there was recently a similar Verb and Target combination by a different Actor, and then replace that earlier instance with a new one that includes the most recent Actor.

I am trying to create a template in NiFi just like a data ingest template which provide by kylo.
Basically I want to allow user to select input data source it can be database or a file. If he selects file and then database processor should automatically gets disabled.
I have create a template in NiFi and imported it kylo, but while creating feed It does not show the feed input option.
How I can do this.
While registering the template, in the "Input Properties" section, you have to select which properties have to be shown in feed creation UI for user input i.e. Enable "Allow user input?"
Attached the screenshot for reference:
I think the best approach here would be to use the RouteOnAttribute as the step after the Data Source/ Data type is chosen.
This way you don't have to overthink it.
I have been working on Kylo for around 3 months now and surely know a thing or two about it.
While starting a Feed, Kylo asks you for which source you want to start a feed no matter you have a single processor or multiple which can act as a data producer or fetcher. Once you select one and start a feed, rest of the source processors get disabled automatically by Kylo in the resultant deployment of feed.
I'm trying to figure out how to extract or find the name of the user who's performing the deployment of an app on a given OpsWorks stack. For example, in the "Deployments and Commands" section of a stack, the table there displays a history of various deployments with who the deploy user was... etc. I'd like to be able to capture that same user from within my recipe.
It doesn't look like it's something I can grab out of search(:aws_opsworks_app) databag (unless I'm mistaken). Or is there somewhere else I can get this information easily?
It turns out there's a pretty simple way to get it through search(:aws_opsworks_command) databag.
:aws_opsworks_command provides an iam_user_arn attribute which can be massaged to appear as the deployment user's IAM name. An example iam_user_arn string look like arn:aws:iam:555555:user/username
Example:
owc = search(:aws_opsworks_command).first
owc[:iam_user_arn].split(':').last
# => gets us "user/username"

I use camunda 7.2.0 and i'm not very experienced with it. I'm trying to write data about users, who had done something with process instance to database (i'm using rest services) to get some kind of reports later. The problem is that i don't know how to trigger my rest(that sends information to datebase about current user and assignee) when user assignes task to somebody else or claims task to himself. I see that camunda engine sends request like
link: engine/engine/default/task/5f965ab7-e74b-11e4-a710-0050568b5c8a/assignee
post: {"userId":"Tom"}
As partial solution I can think about creating a global variable "currentUser" and on form load check if user is different from current, and if he is - run the rest and change variable. But this solution don't looks correct to me. So is there any better way to do it? Thanks in advance
You could use a task listener which updates your data when the assignee of a task is changed. If you want this behavior for every task you could define a global task listener.
I am developing a integration between a desktop application and Amazon MWS and need to be able to offer users a choice of categories to put the product they are listing into. My problem is that I can't find any way of programmatically getting the current categories from MWS using the API.
Additionally once I have a category reference to use I will need a way to the pull in and add the category specific XML child of ProductData (eg Home, Jewelry, Computers, etc) but they don't seem to be linked in any well defined way. For example, I can't say "if the chosen category is reference nnnnn ask them to populate the Computers specific ProductData", unless I write something myself to map them.
Has anyone else come across these problems and found a workable solution?
Any help appreciated...
I am currently exploring the option of limiting users to only selling products already listed on Amazon but still can't figure out how to pull in the correct category specific XML.
There are various product look-ups but they all seem to work from either my SKU (which will not yet be there) or Amazons ASIN (which I don't yet know)
You can use amazon advertizement api for this.
You have to create account on amazon affiliate programme.From that you have to get security credentials also .
After That go to BrowseNode Tree Page and download root categories list and save it to file or database.From there you get categoryname and their browseNodeId.
Then call BrowseNodeApi to get Child Categories for parent Category.
Please Follow This Link
http://docs.aws.amazon.com/AWSECommerceService/latest/DG/ProgrammingGuide.html
code for calling BrowseNodeApi
SignedRequestHelper helper =
new SignedRequestHelper(appConfig["AWSAccessKey"], appConfig["AWSSecretKey"], appConfig["endpoint"]);
string url = helper.Sign("http://ecs.amazonaws.com/onca/xml?Service=AWSECommerceService&Operation=BrowseNodeLookup&BrowseNodeId=" + value + "&AssociateTag=beginners00-00&Version=2011-08-01");
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
// Get response
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
}
and also download SignatureGenerator class HMAC
My app download all the user's friends pictures.
All the requests are of this kind:
https://graph.facebook.com/<friend id>/picture?type=small
But, after a certain limit is reached, instead of the picture I get:
{"error""message":"(#4) Application request limit reached","type":"OAuthException"}}
Actually, the only way I found to prevent this is to change the server ip (manually).
There isn't a better way?
For the record:
The limit is related to the Graph Api only, and the graph.facebook.com/<user>/picture url is a graph api call that returns a redirect.
So, to avoid the daily limit, simply fetch all the images url from FQL, like:
SELECT uid, pic_small, pic_big, pic, pic_square FROM user WHERE uid = me() or IN (SELECT uid2 FROM friend WHERE uid1=me())
now these are the direct urls to the images, for eg:
http://profile.ak.fbcdn.net/hprofile-ak-snc4/275716_1546085527_622218197_q.jpg
so don't store them since they continuously change.
If it's needed for an online app better way not to download those images, but use an online version, there is couple of reasons for doing so:
Users change pictures (some frequently), do you need an updated version?
Facebook's servers probably faster than yours and friends pictures probably cached within browser of your user.
Update:
Since limit you reach is Graph API call limit, not the image retrieval, another solution that comes to my head just now is using friends connection of user in Graph API and specifying picture in fields argument, eq: https://graph.facebook.com/me/friends?fields=picture, this will return direct URL-s for friends pictures so you can do only one call to get all needed info to download the images for every user...
