Why IBKR API keeps showing ___ object has no attribute ___? - api

extra information below:
I think the connection is established (I opened TWS and did the right settings for API)
I made the right virtual environment with anaconda
I move all the relevant TWS files to the folder and set up the terminal with the virtual environment there.

Your historicalData method accesses an instance variable named data that hasn't been created. Assuming data is a dictionary, you can create it by adding a line to __init__:
def __init__(self):
EClient.__init__(self, self)
data = {}

ANSYS Mechanical Workbench Scripting - Accessing Parameters

Ansys gurus,
My project is a static structural analysis using ANSYS workbench mechanical. I have created the parametrized geometry (via Design modeler) and material property in workbench, and used ACT scripting to configure the model. However, I don't find too much information on how to access the parameters via ACT scripting.
I have confirmed that the geometric parameters are successfully created in the workbench, e.g.
ID
Paramater Name
Value
Unit
P1
diameter
50
um
The documentation LINK suggests that I can obtain parameter ID using Analysis.GetParameter(), however, the following code didn't work for me and resulted in the error as below.
Code:
STATIC_STRUCTURAL = ExtAPI.DataModel.AnalysisByName("Static Structural")
HEIGHT = STATIC_STRUCTURAL.GetParameter('height')
Error:
Property not found.
Do you have any suggestions on the cause of such error, is it because the Parameters were not imported from workbench "project schematic" to "Model", or the code I tried to retrieve the parameters was incorrect. In either cases, could you advise the correct method to access the parameters? Thank you!

If you want to access a parameter from the "project schematic" page you can create a list. If you than want to do something with this inside of mechanical, you have to send the commands to your model:
# Access the geometric parameters
allParameters = Parameters.GetAllParameters()
for parameter in allParameters:
print parameter.DisplayText
if parameter.DisplayText == 'height':
heigthParameter = parameter
# Loop over all systems in the project
for system in GetAllSystems():
# Get Model Container
model = system.GetContainer(ComponentName="Model")
# edit model component in batch mode
system.Refresh()
model.Edit(Interactive=True)
# code to be sent to ansys mechanical
cmd ='''
here goes your ACT script as string. You have to make sure, that there are no leading spaces or tabs.
'''
# send code and exit mechanical
model.SendCommand(Language='Python',Command=cmd)
model.Exit()
print "Finished script execution."

Repast: how to add and set a new parameter directly from the code instead of GUI

I want to create a parameter that contains a list of string (list of hub codes). This list of string is created by reading an external csv file (this list could contain the different codes depending on the hub codes in the CSV file)
What I want is to find a easy auto way to perform batch runs by each hub code in the list.
So this question is:
1) how to add and set a new parameter directly from the code (during the initialization when reading the CSV) instead of GUI parameter panel?
2) how to avoid manual configuration of hub list in the batch run configuration
Something like this for adding the parameters should work in your ContextBuilder.
Parameters params = RunEnvironment.getInstance().getParameters();
((DefaultParameters)params).addParameter("foo", "Big Foo", Integer.class, 3, false);
You would read the csv file to get the parameter name and value.
I'm not sure I completely understand the batch run configuration question, but each batch run has a run number associated with it
RunState.getInstance().getRunInfo().getRunNumber()
If you can associate line numbers in your csv parameter file with run number (e.g. run number 1 should use line 1, and so on), then each batch run would use a different parameter line.

Running code when mongoengine loads a document

We are trying to run code that modifies a document when it loads as part of schema maintenance. We have a document such as
from mongoengine import Document
from mongoengine.fields import IntField, StringField
class User(Document):
version = IntField(default=0)
name = StringField()
Instances of User are created with version=1 and saved.
Later on, we modify this class as follows:
class User(Document):
version = IntField(default=0)
name = StringField(max_length=20)
Some of the version 1 documents now need to be truncated:
def upgrade_1_to_2(self):
self.name = self.name[:20]
We want to automatically run that function whenever a User is retrieved from the database, and only if version == 1. (Future upgrades would be upgrade_2_to_3(), and so on.)
Where in this API can I put code that runs when a document is retrieved?
Looks like it's a good candidate for the post_init signal and you can do a check there.
See: http://docs.mongoengine.org/guide/signals.html

How can I reference a TestCase property from an AMF request TestStep script in soapUI?

I have a Test Case called "testCaseOne"
It contains three Test Steps:
"AMFrequestOne"
"propertyTransfer"
"AMFrequestTwo"
"AMFrequestOne" creates a database object.
"propertyTransfer" sends the ResponseAsXml to a temporary property in "testCaseOne" called "tempProp".
I need to reference "tempProp" in a script inside of "AMFrequestTwo"
I've tried the following
def temp = testRunner.testCase.getPropertyValue( "tempProp" )
but I get the error "No such property: testRunner for class: Script6" (number increments with tries)
Is this because in an AMF request "Script is invoked with log, context, parameters and amfHeaders variables" and testRunner is not recognized?
I know it seems odd, but is it possible to do this? I'm unable to use a specific xpath property transfer between the two AMF Requests as it's possible for the structure to change and I'm not always looking for the same node.
Used
def temp = context.testCase.getPropertyValue( "tempProp" )
instead of
def temp = testRunner.testCase.getPropertyValue( "tempProp" )
and this works fine.

MsTest, DataSourceAttribute - how to get it working with a runtime generated file?

for some test I need to run a data driven test with a configuration that is generated (via reflection) in the ClassInitialize method (by using reflection). I tried out everything, but I just can not get the data source properly set up.
The test takes a list of classes in a csv file (one line per class) and then will test that the mappings to the database work out well (i.e. try to get one item from the database for every entity, which will throw an exception when the table structure does not match).
The testmethod is:
[DataSource(
"Microsoft.VisualStudio.TestTools.DataSource.CSV",
"|DataDirectory|\\EntityMappingsTests.Types.csv",
"EntityMappingsTests.Types#csv",
DataAccessMethod.Sequential)
]
[TestMethod()]
public void TestMappings () {
Obviously the file is EntityMappingsTests.Types.csv. It should be in the DataDirectory.
Now, in the Initialize method (marked with ClassInitialize) I put that together and then try to write it.
WHERE should I write it to? WHERE IS THE DataDirectory?
I tried:
File.WriteAllText(context.TestDeploymentDir + "\\EntityMappingsTests.Types.csv", types.ToString());
File.WriteAllText("EntityMappingsTests.Types.csv", types.ToString());
Both result in "the unit test adapter failed to connect to the data source or read the data". More exact:
Error details: The Microsoft Jet database engine could not find the
object 'EntityMappingsTests.Types.csv'. Make sure the object exists
and that you spell its name and the path name correctly.
So where should I put that file?
I also tried just writing it to the current directory and taking out the DataDirectory part - same result. Sadly, there is limited debugging support here.
Please use the ProcessMonitor tool from technet.microsoft.com/en-us/sysinternals/bb896645. Put a filter on MSTest.exe or the associate qtagent32.exe and find out what locations it is trying to load from and at what point in time in the test loading process. Then please provide an update on those details here .
After you add the CSV file to your VS project, you need to open the properties for it. Set the Property "Copy To Output Directory" to "Copy Always". The DataDirectory defaults to the location of the compiled executable, which runs from the output directory so it will find it there.
