Having a really aggravating problem using Managed Metadata in SP2010 where I can get a Taxonomy Session, Term Store and Term set fine, but when I try to retrieve a term from the term set, I get a TermStoreOperationException which says that it "failed to read from or write to database".
Does anyone have any idea as to why I can get the Term Set but not the terms? I can't quite understand why when they all reside in the same database I can get the set but not the terms within it.
The code I'm using is below:
TaxonomySession txSession = new TaxonomySession(site, true);
TermStore termStore = txSession.DefaultSiteCollectionTermStore;
TermSet termSet = termStore.GetTermSet(TermSetId);
TermCollection termCollection = termSet.GetTerms("My Term", true); //exception thrown on this line.
Any ideas or insight or solutions would be really appreciated.
Thanks heaps!
I managed to get around this by getting the Term just by using the indexer on the Term Set:
TermSet termSet = termStore.GetTermSet(txField.TermSetId);
Term myTerm = termSet.Terms["My Term"]);
I'm not sure why .GetTerms() doesn't work - it might be because SP2010 is still not RTM and it's meant to be an internal method, or some other mysterious reason beyond my comprehension...

I'm currently building a new moodle plugin. I'm using add_moduleinfo and update_moduleinfo. To add a new attandance atictivity in a course and update it later on.
Sadly I'm facing the issue that update_moduleinfo always throws an "invalid course module id" error. I already checked the cm entry in my database to ensure im using the right module instance.
I dont really know what to do.
$cm = get_coursemodule_from_instance($moduleName, $activityID, $course->id);
$moduleinfo = update_moduleinfo($cm, $moduleinfo, $course); <-- Error
Thats how I try to update the entry.
I also found that post. Didn't help anything.
Moodle - Invalid course module ID
I found the issue myself:
$moduleinfo->introeditor['format'] = FORMAT_HTML;
$moduleinfo->introeditor['text'] = "INTRO TEXT";
$moduleinfo->coursemodule = $cm->id;
list($cm, $moduleinfo) = update_moduleinfo($cm, $moduleinfo, $course, null);
In order to use this function the above mentioned properties need to exist in order to perform a update.
I am trying to call the language detection method of the translate client api from pyspark for each row in a file.
I created a map method as the following but the job seems to just freeze with no error. If I remove the call to the translate API it executes fine. Is it possible to call Google client API methods within pySpark map ?
mapping method to do translation
def doTranslate(data):
translate_client = translate.Client()
# Get the message information
messageId = data[0]
messageContent = data[6]
detectedLang = translate_client.detect_language(messageContent)
r = []
r.append(detectedLang)
return r
Figured it out!! your question led me in the right direction. thanks!
Turns out I was getting an exception from the call because I was going past the default quota for sizes of messages. I added a try/except block and determined this was the problem. Then cutting the message size down (I am just testing so dont want to mess with the quota) fixed the issue.
I have a strange MEF problem, I tested this in a test project and it all seems to work pretty well but for some reason not working in the real project
This is the exporting code
public void RegisterComponents()
{
_registrationBuilder = new RegistrationBuilder();
_registrationBuilder
.ForTypesDerivedFrom(typeof(MyType))
.SetCreationPolicy(CreationPolicy.NonShared)
.Export();
var catalog = new AggregateCatalog();
catalog.Catalogs.Add(new AssemblyCatalog(typeof(MyType).Assembly, _registrationBuilder));
var directoryCatalog = new DirectoryCatalog(PathToMyTypeDerived, _registrationBuilder);
catalog.Catalogs.Add(directoryCatalog);
_compositionContainer = new CompositionContainer(catalog);
_compositionContainer.ComposeParts();
var exports = _compositionContainer.GetExportedValues<MyType>();
Console.WriteLine("{0} exports in AppDomain {1}", exports.Count(), AppDomain.CurrentDomain.FriendlyName);
}
exports count is 0 :( Any ideas why?
IN the log file I have many of this
System.ComponentModel.Composition Information: 6 : The ComposablePartDefinition 'SomeOthertype' was ignored because it contains no exports.
Though I would think this is ok because I wasn' interested in exporting 'someOtherType'
UPDATE: I found this link but after debuging over it I am not wiser but maybe I m not following up properly.
Thanks for any pointers
Cheers
I just had the same problem and this article helped me a lot.
It describes different reasons why a resolve can fail. One of the more important ones is that the dependency of a dependency of the type you want to resolve is not registered.
What helped me a lot was the the trace output that gets written to the Output window when you debug your application. It describes exactly the reasons why a type couldn't be resolved.
Even with this output. you might need to dig a little bit, because I only got one level deep.
Example:
I wanted to resolve type A and I got a message like this:
System.ComponentModel.Composition Warning: 1 : The ComposablePartDefinition 'Namespace.A' has been rejected. The composition remains unchanged. The changes were rejected because of the following error(s): The composition produced multiple composition errors, with 1 root causes. The root causes are provided below. Review the CompositionException.Errors property for more detailed information.
1) No exports were found that match the constraint:
ContractName Namespace.IB
RequiredTypeIdentity Namespace.IB
Resulting in: Cannot set import 'Namespace.A..ctor (Parameter="b", ContractName="namespace.IB")' on part 'Namespace A'.
Element: Namespace.A..ctor (Parameter="b", ContractName="Namespace.IB") --> Namespace.A --> AssemblyCatalog (Assembly="assembly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=...")
But I clearly saw a part for Namespace.IB. So, in the debugger, I tried to resolve that one. And I got another trace output. This time it told me that my implementation of Namespace.IB couldn't be resolved because for one of its imports there was a missing export, so basically the same message as above, just with different types. And this time, I didn't find a part for that missing import. Now I knew, which type was the real problem and figure out, why no registration happened for it.
I have some code which was working at one point but no longer works, which strongly suggests that the redmine configuration is involved somehow (I'm not the redmine admin), but the lack of any error messages makes it hard to determine what is wrong. Here is the code:
#!/usr/bin/env ruby
require "rubygems"
gem "activeresource", "2.3.14"
require "active_resource"
class Issue < ActiveResource::Base
self.site = "https://redmine.mydomain.com/"
end
Issue.user = "myname"
Issue.password = "mypassword" # Don't hard-code real passwords :-)
issue = Issue.find 19342 # Created manually to avoid messing up real tickets.
field = issue.custom_fields.select { |x| x.name == "Release Number" }.first
issue.notes = "Testing at #{Time.now}"
issue.custom_field_values = { field.id => "Release-1.2.3" }
success = issue.save
puts "field.id: #{field.id}"
puts "success: #{success}"
puts "errors: #{issue.errors.full_messages}"
When this runs, the output is:
field.id: 40
success: true
errors: []
So far so good, except that when I go back to the GUI and look at this ticket, the "notes" part is updated correctly but the custom field is unchanged. I did put some tracing in the ActiveRecord code and that appears to be sending out my desired updates, so I suspect the problem is on the server side.
BTW if you know of any good collections of examples of accessing Redmine from Ruby using the REST API that would be really helpful too. I may just be looking in the wrong places, but all I've found are a few trivial ones that are just enough to whet one's appetite for more, and the docs I've seen on the redmine site don't even list all the available fields. (Ideally, it would be nice if the examples also specified which version of redmine they work with.)
I'm trying to better understand common strategies regarding results and errors in Celery.
I see that results have statuses/states and stores results if requested -- when would I use this data? Should error handling and data storage be contained within the task?
Here is a sample scenario, in case it helps better understand my objective:
I have a geocoding task that goeocodes user addresses. If the task fails or succeeds, I'd like to update a field in the database letting the user know. (Error handling) On success I'd like the geocoded data to be inserted into the database (Data storage)
What approach should take?
Let me preface this by saying that I'm still getting a feel for Celery myself. That being said, I have some general inclinations about how I'd go about tackling this, and since no one else has responded, I'll give it a shot.
Based on what you've written, a relatively simple (though I suspect non-optimized) solution is to follow the broad contours of the blog comment spam task example from the documentation.
app.models.py
class Address(models.Model):
GEOCODE_STATUS_CHOICES = (
('pr', 'pre-check'),
('su', 'success'),
('fl', 'failed'),
)
address = models.TextField()
...
geocode = models.TextField()
geocode_status = models.CharField(max_length=2,
choices=GEOCODE_STATUS_CHOICES,
default='pr')
class AppUser(models.Model):
name = models.CharField(max_length=100)
...
address = models.ForeignKey(Address)
app.tasks.py
from celery import task
from app.models import Address, AppUser
from some_module import geocode_function #assuming this returns a string
#task()
def get_geocode(appuser_pk):
user = AppUser.objects.get(pk=appuser_pk)
address = user.address
try:
result = geocode_function(address.address)
address.geocode = result
address.geocode_status = 'su' #set address object as successful
address.save()
return address.geocode #this is optional -- your task doesn't have to return anything
on the other hand, you could also choose to decouple the geo-
code function from the database update for the object instance.
Also, if you're thinking about chaining tasks together, you
might think about if it's advantageous to pass a parameter as
an input or partial input into the child task.
except Exception as e:
address.geocode_status = 'fl' #address object fails
address.save()
#do something_else()
raise #re-raise the error, in case you want to trigger retries, etc
app.views.py
from app.tasks import *
from app.models import *
from django.shortcuts import get_object_or_404
def geocode_for_address(request, app_user_pk):
app_user = get_object_or_404(AppUser, pk=app_user_pk)
...etc.etc. --- **somewhere calling your tasks with appropriate args/kwargs
I believe this meets the minimal requirements you've outlined above. I've intentionally left the view undeveloped since I don't have a sense of how exactly you want to trigger it. It sounds like you also may want some sort of user notification when their address can't be geocoded ("I'd like to update a field in a database letting a user know"). Without knowing more about the specifics of this requirement, I would it sounds like something that might be best accomplished in your html templates (if instance.attribute value is X, display q in template) or by using a django.signals (set up a signal for when a user.address.geocode_status switches to failure -- say, by emailing the user to let them know, etc.).
In the comments to the code above, I mentioned the possibility of decoupling and chaining the component parts of the get_geocode task above. You could also think about decoupling the exception handling from the get_geocode task, by writing a custom error handler task, and using the link_error parameter (for instance., add.apply_async((2, 2), link_error=error_handler.s(), where error_handler has been defined as a task in app.tasks.py ). Also, whether you choose to handle errors via the main task (get_geocode) or via a linked error handler, I would think that you would want to get much more specific about how to handle different sorts of errors (e.g., do something with connection errors different than with address data being incorrectly formatted).
I suspect there are better approaches, and I'm just beginning to understand how inventive you can get by chaining tasks, using groups and chords, etc. Hope this helps at least get you thinking about some of the possibilities. I'll leave it to others to recommend best practices.
