I have been trying to add a new table to the database. Now, I have created
the table and I am going through conductor API to populate/update it. I have
defined some function to achieve the task. There function are defined in conductor
and db api, along with in conductor.manage and db.sqlalchemy.api. When I try
to run the system it says
AttributeError: 'ConductorAPI' object has no attribute 'xxxxxx'
while the function is properly defined in Conductor API as well as manager and
db.API. I back traced the flow of the code and it looks like the code reaches till
conductor.api. The function at the conductor API is defined as:
"""In class LocalAPI"""
def xxxxxx(self, context, node_id, values):
return self._manager.xxxxxx(context, node_id, values)
Now, after this it gives the error. Though the function is present in conductor.manager.
Please help me find out why am I getting this error.
So, I figured it out. You also need to add the interface to the conductor.rpcapi and now it's working fine!

So I'm playing with Twilio Studio, and building a sample IVR. I have it doing a web request to an API that looks up the customer based on their phone number. That works, I can get/say their name to them.
I'm having trouble with the next step, I want to do another http request and pass the 'customer_id' that I get in webrequest1 to webrequest2, but it almost looks like all the web requests fire right when the call starts instead of in order/serialized.
It looks sorta like this;
call comes in, make http request to lookup customer (i get their customer_id and name)
split on content, if customer name is present, (it is, it goes down this decision path)
do another http request to "get_open_invoice_count", this request needs the customer_id though and not their phone number.
From looking at the logs it's always got a blank value there, even though in the "Say" step just above I can say their customer_id and name.
I can almost imagine someone is going to say I should go use a function, but for some reason I can't get a simple function to do a (got) get request.
I've tried to copy/paste this into a function and I kind of think this example is incomplete: https://support.twilio.com/hc/en-us/articles/115007737928-Getting-Started-with-Twilio-Functions-Beta-
var got = require('got');
got('https://swapi.co/api/people/?search=r2', {json: true})
.then(function(response) {
console.log(response)
twiml.message(response.body.results[0].url)
callback(null, twiml);
})
.catch(function(error) {
callback(error)
})
If this is the right way to do it, I'd love to see one of these ^ examples that returns json that can be used in the rest of the flow. Am I missing something about the execution model? I'm hoping it executes step by step as people flow through the studio, but I'm wondering if it executes the whole thing at boot?
Maybe another way to ask this question is; If I wanted to have the IVR be like
- If I know who you are, i send you down this path, if I know who you are I want to lookup some account details and say them to you and give you difference choices than if you are a stranger.
---- how do you do this?
You're right -- that code excerpt from the docs is just a portion that demonstrates how you might use the got package.
That same usage in context of the complete Twilio Serverless Function could look something like this:
exports.handler = function(context, event, callback) {
var twiml = new Twilio.twiml.MessagingResponse();
var got = require('got');
got('https://example.com/api/people/?search=r2', { json: true })
.then(function(response) {
console.log(response);
twiml.message(response.body.results[0].url);
callback(null, twiml);
})
.catch(function(error) {
callback(error);
});
};
However, another part of the issue here is that the advice in this documentation is perfectly reasonable for Functions when building an app on the Twilio Runtime, but there are a couple of unsaid caveats when invoking these functions from a Studio Flow context. Here's some relevant docs about that: https://support.twilio.com/hc/en-us/articles/360019580493-Using-Twilio-Functions-to-Enhance-Studio-Voice-Calls-with-Custom-TwiML
This function would be acceptable if you were calling it directly from an inbound number, but when you use the Function widget within a Studio flow to return TwiML, Studio releases control of the call.
If you want to call external logic that returns TwiML from a flow, and want to return to that flow later, you need to use the TwiML Redirect widget (see "Returning control to Studio" for details).
However, you don't have to return TwiML to Studio when calling external logic! It sounds like you want to make an external call to get some information, and then have your Flow direct the call down one path or another, based on that information. When using a Runtime Function, just have the function return an object instead of twiml, and then you can access that object's properties within your flow as liquid variables, like {{widgets.MY_WIDGET_NAME.parsed.PROPERTY_NAME}}. See the docs for the Run Function widget for more info. You would then use a "Split Based On..." widget following the function in your flow to direct the call down the desired branch.
The one other thing to mention here is the Make HTTP Request widget. If your Runtime Function is just wrapping a call to another web service, you might be able to get away with just using the widget to call that service directly. This works best when the service is under your control, since then you can ensure that the returned data is in a format that is usable to the widget.
I'm a beginner in Ionic and Firebase. To learn using ionic+firebase, I'm writing a RandomQuote app to fetch a random entry from Firebase. A reload() method is called when I click a reload button, and the random quote is displayed as expected.
However, I also want the quote to display when the app is loaded, i.e., before I click the reload button. I call the reload() method in the constructor but it doesn't work. I have tried to search for answers on the web but cannot find anything that I could understand. Not sure if I'm searching the wrong keywords or in the wrong domains.
The following is the reload() method that I put in my FirebaseProvider class and called from my home.ts:
reload(){
this.afd.list('/quoteList/').valueChanges().subscribe(
data => {
this.oneQuote = data[Math.floor(Math.random() * data.length)];
}
)
return this.oneQuote;
}
Can anyone give me some hints? Or any pointer to useful books / materials for beginners will also be highly appreciated. Thank you very much.
Data is loaded from Firebase asynchronously. This means that by the time your return statement runs this.oneQuote doesn't have a value yet.
This is easiest to say by placing a few log statements around your code:
console.log("Before subscribing");
this.afd.list('/quoteList/').valueChanges().subscribe(
data => {
console.log("Got data");
}
)
console.log("After subscribing");
When you run this code, the output is:
Before subscribing
After subscribing
Got data
This is probably not what you expected. But it completely explains why your return statement doesn't return the data: that data hasn't been loaded yet.
So you need to make sure your code that needs the data runs after the data has been loaded. There are two common ways to do this:
By moving the code into the callback
By returning a promise/subscription/observable
Moving the code into the callback is easiest: when the console.log("Got data") statement runs in the code above, the data is guaranteed to be available. So if you move the code that requires the data into that place, it can use the data without problems.
Returning a promise/subscription/observable is a slightly trickier to understand, but nicer way to doing the same. Now instead of moving the code-that-needs-data into the callback, you'll return "something" out of the callback that exposes the data when it is available. In the case of AngularFire the easiest way to do that is to return the actual observable itself:
return this.afd.list('/quoteList/').valueChanges();
Now the code that needs the quotes can just subscribe to the return value and update the UI:
reload().subscribe(data => {
this.oneQuote = data[Math.floor(Math.random() * data.length)];
}
A final note: having a reload() method sounds like an antipattern. The subscription will already be called whenever the data in the quoteList changes. There is no need to call reload() for that.
I am trying to place a date time picker in my form. However, I get an error that says Invariant Violation, Target is not in the DOM. I am very new to javascript as well as meteor and react. What does this error mean and how can I fix it?
Here is the code: https://gist.github.com/drwofle21/8cffed99312711ddfb3f
As the comment on the Gist said "document.getElementsByClassName("calendar") Will return an array, not single node."
That array contains a list of nodes that you can loop through. Best thing to do is console log it out and see what it's actually returning and how you can best handle it.
I have a local package with the following code
#articleSubmitMethodCallbacks = []
articleSubmitMethodCallbacks.push(addThumbnailOnSubmit)
This works and returns an array with a function in.
Then I have a method called articleInsert
In that method I have the following code
article = articleSubmitMethodCallbacks.reduce(((result,currentFunction)->
return currentFunction (result)
), article)
Now for some reason, every time I call this method, articleSubmitMethodCallbacks stays an empty array, even though before it ran it has the function in it. It somehow gets reset, any idea why this happens?
Okay strange answer but here it goes, apparently it has something to do with the naming articleSubmitMethodCallbacks that interferes with something inside Meteor.
If I use any other array name, it works perfect. To be clear I didn't overwrite articleSubmitMethodCallbacks anywhere and in fact the code above was the only reference to it in the whole project.
in Flex 3.2 Having troubles converting remote object result to specific object on client side in modules.
For example I have VIPSAdmin module.
it has function
private function doResult(event:ResultEvent):void {
var data_:Array = ArrayUtil.toArray(event.result);
var result:ResultDTO = data_[0] as ResultDTO;
if(!result.isError()) {
trace(result.result);
vipsAdminDTO = result.result as VIPSAdmin;
compId= vipsAdminDTO.compId; // second time dying here
}
}
Function invoked when I get data from remote objet.
First time all great,when I unload this modeule and load it again:
data_[0] as ResultDTO;
Performs fine, but
vipsAdminDTO = result.result as VIPSAdmin;
vipsAdminDTO always null!
Even when
trace(result.result);
produces [object VIPSAdmin]
What a heck I missing here!? Looks like it just cannot do
result.result as VIPSAdmin;
even when trace and debug says it is instance of VIPSAdmin
I've figured out what is the problem, problem is that when I first instantiate something in module then in main app, somehow classes are not alined even that they are identical !
So solution is to make a fake instance in application class first, then if you use that same class to make an instance in module it will work!
I do it very simple in my main application class I just added:
VIPSAdmin;
This seems to create some sort of ghost instance, which I belie will be pickup by GC later, but will build tables of instances properly! Which solved my problem.
Not sure if this is appropriate solution ! but it sure works.
