I'm experimenting with a Conversation where I would like to modify the output in a couple of different ways:
different output for speech or text
different output depending on the tone of the conversation
It looks like I can add extra output details which make it through to the client ok. For example, adding speech alongside text...
{
"output": {
"speech": {
"Hi. Please see my website for details."
},
"link": "http://www.example.com",
"text": {
"Hi. Please see http://www.example.com for details."
}
}
}
For the tone, I wondered about making up a custom selection policy, unfortunately it seems to treat it the same as a random selection policy. For example...
{
"output": {
"text": {
"values": [
"Hello. Please see http://www.example.com for more details.",
"Hi. Please see http://www.example.com for details."
]
},
"append": false,
"selection_policy": "tone"
}
}
I could just add a separate tone-sensitive object to output though so that's not a big problem.
Would there be any issues adding things to output in this way?
You can definitely use the output field to specify custom variables you want your client app to see with the benefit that these variables will not persist across multiple dialog rounds (which they would if you would add them to the context field).
Now currently there is no "easy" way how to define your custom selection policy (apart from the random and sequential supported by the runtime right now) - but you could still return an array of possible answers to the client app with some attribute telling the client app which selection policy to use and you would implement this policy in the client app.

I created a Json Server Database like this:
"Time":
[
{
"id":1,
"name":
[
{
"id":1,
"checkin":
[
{
"id":1,
"date":"123",
"time":"123"
},
{
"id":2,
"date":"123",
"time":"123"
}
]
},
{
"id":2,
"checkout":
[
{
"id":1,
"date":"123",
"time":"123"
}
]
}
]
}
]
I don't want to get the entire Database and go through it. I just want to tell the Database where exactly my Object is and have it returned.
How would I call the call for example the first Check-in Object?
I use the Angular HttpClient like this:
this.http.get(endpoint, JSON.stringify(time), this.httpOptions))
So I need the Exact Endpoint in a format like: endpoint/id/id or similar
I imagined it like this: endpoint/time/1/1
With output:
[
{
"id":1,
"date":"123",
"time":"123"
}
]
If this is not possible please tell me anyways.
PS: The question from this thread is essentially the same as mine. Also the JSON documentation doesn't real help either, it just says you need custom routes for multilayer JSON strings but not how to implement these routes.
I'm not sure if I understand correctly where you are returning the data from. If you meant json-server, just look at the documentation (here) and then you could use an endpoint like "/posts?Id=2"
However, if you mean your own API, which does not have an endpoint that returns one record, e.g. by its ID, the only convenient solution is to create a service that will map the result from the server and return the desired value.
You can do all this in one place, but for clearer code, I recommend dividing it into:
service that will download data from the server
service that will map the data on the basis of a given parameter
component that will display the data
Below is a working example on Stackblitz.
example
Note that in the app-component I pass the ID 32 to the method from the mapping service as the parameter. The mapping service then calls a method that sends the request for all the data.
The important thing is that all data is returned to the application, not just one record. If the API you are using does not provide such an endpoint, it is not possible to return only one record.
Apparently a request like I wanted to call is still not possible. The only way to come close is to fake it with custom Routes and flattening the JSON structure like in this old thread.
I am using a Blumix free account to develop a chat-bot using watson conversation.
How do I add a clickable URL in the response, or automatically call a URL in browser?
I have edited the "advanced response" using the suggestions as described on this page but could not get it work.
How can I achieve that?
I don't know if I understood your question correctly, but.. if you wants add some url inside flows Conversation Service (IBM Watson), try it:
1º: Add the url with tag <a target> and href= your URL inside flows. See the example:
JSON:
"output": {
"text": "This is a link <a target=\"_blank\" href= \"https://www.choosemyplate.gov\">Food and nutrition Guide</a>.\n<br/><br/>Talk to you later, bye for now!"
},
2º See that it did not work inside the Conversation, because it will be your browser that will render the html.
3º If you open with your browser, it works, see:
See that the link is showing up, and this will work for other things in html, like button, for example...
But if you can: based on user input should access a url:
This is done by using two features: Context.request skip_user_input
A request is a special context variable that has args, name and result. It is used to tell the calling app that it should do some action based on this variable.
Setting skip_user_input is optional. In many cases, you might want to execute some business logic in your application and then provide its results via result. Setting skip_user_input to true, will tell Watson Conversation to not wait for input from the user. Thus, your condition on the next node should be based on the content inside result.
{
"output": {},
"context": {
"request": {
"args": {
"url_to_invoke": "your_url"
},
"name": "Call_A_URL",
"result": "context.response"
},
"skip_user_input": true
}
}

I'm working with this list videos example for GAE and if you try to run it on that page you can see that there's no next_page_token
I've even tried to self.response.out.write(next_page_token) and got None.
For example purposes I've submitted Channel name to be Google (which surely has more than 50 videos). I only get 50, no token that I can see, no pagination indication or anything like that.
What am I missing here?
Please advise,
Thanks a lot
Here is the first request pre-filled for you. Click execute at the bottom:
https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.channels.list?part=snippet%252CcontentDetails&forUsername=Google&_h=1&
Following that result and hitting the next api in the code,
https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.playlistItems.list?part=snippet&maxResults=50&playlistId=UUK8sQmJBp8GCxrOtXWBpyEA&_h=3&
Clicking execute on that shows that nextPageToken set. Either the code example from Google has a bug in it, or it is a copy paste error somewhere.
EDIT:
There is a bug in the code sample provided.
playlistitems_response looks similar to this:
{
"kind": "youtube#playlistItemListResponse",
"etag": "\"eYE31WLho912TfxEBDDRSwEQ5Ms/vUtg-sAFafmsExy-5XOvaMIfVN0\"",
"nextPageToken": "CDQQAA",
"prevPageToken": "CDIQAQ",
"pageInfo": {
"totalResults": 1634,
"resultsPerPage": 2
},
"items": [{...}]
}
The nextPageToken is being extracted like playlistitems_response.get('tokenPagination', {}).get('nextPageToken') when it
should read playlistitems_response.get('nextPageToken').
I have a successful connection setup between a FTP site and dropbox using a azure logic app. But while setting it up it kept just downloading the file then, since I had the next step wrong, deleting.
In a test environment this is annoying. In production, pretty awful.
Here is the code I am using on the action part:
"operation": "UploadFile",
"parameters": {
"FilePath": "#{triggers().outputs.body.FilePath}",
"content": {
"Content": "#{triggers().outputs.body.Content}",
"ContentTransferEncoding": "None"
},
"overwrite": true
},
Is there anything I can do so that if it fails it leave the file on the server?
I'm not 100% sure what you mean, but I will give it a try. Maybe you can reformulate the question if I misinterpret you.
But yes, there exists "conditions" in Logic Apps which can be used. If you are new to Logic Apps I'd suggest you use "designer view" and you can then click "Add condition to be met". This would visualize a text box in which you can formulate conditions. For instance:
#equals({your data}, bool('true'))
To check if some value is true, or something similar to check if data is null.
I'm currently writing an administrative interface using the Loopback Angular SDK. After having dug through the documentation and code, I'm still no wiser as to how to include the user's roles in the response. It's causing me real headaches on the frontend because I'm not yet experienced enough with Angular to figure out how to enforce a role check on each of my states (I'm using UI-Router).
client: /auth.js
// Log the user in
$scope.doAuth = function() {
$scope.hasError = false;
$scope.busy = true;
$scope.loginResult = User.login({include: 'roles'}, $scope.credentials,
function wasSuccessfulAuth(authResponse) {
$scope.busy = true;
$rootScope.isAuthenticated = true;
$rootScope.user = authResponse.user;
$location.path('dashboard');
},
function wasFailedAuth(authResponse) {
$timeout(function() {
$scope.hasError = true;
$scope.authError = authResponse.data.error.message || 'Unknown error';
$scope.busy = false;
}, 1000);
}
)
}
server: /common/models/user.json
{
"name": "user",
"plural": "Users",
"base": "User",
"properties": {
},
"relations": {
"roles": {
"type": "belongsTo",
"model": "RoleMapping",
"foreignKey": "principalId"
}
},
"acls": [],
"methods": []
}
So this works in the API explorer, I have the routes I'd expect with an object that has a relation, but I can't seem to get any further than that... All that gets returned is the standard user login stuff (id, accessToken, email, etc) The docs seem to run cold when I get this far but I'd have thought this would have been a common use case?
This is a bit of a showstopper for me.
It's actually surprisingly easy to solve this problem using LoopBack: this is where "model scopes" come in very handy -- including the default scope which I find extremely useful for this type of situation.
First, a brief explanation of model scopes:
A model scope is like a saved query or "view", that allows you to specify a built-in filter for any query for that scope. For example, if you set the default scope to a valid filter, every single query (of any kind) against your model will have this filter applied!
This can get you in a heap of trouble, but there's one use-case that's pretty safe (all other things equal) and actually addresses your question perfectly: when I said a scope lets you give a valid filter, it turns out filters aren't just where clauses, but also include, limit, etc.
So to solve your problem, you simply need a default scope on your User model that includes whatever you need to include. For your example:
Simply add a scope object to your common/models/user.json:
{
"name": "user",
"plural": "Users",
"base": "User",
"scope": {
"include": [
"roles"
]
},
"properties": {
},
"relations": {
"roles": {
"type": "belongsTo",
"model": "RoleMapping",
"foreignKey": "principalId"
}
},
"acls": [],
"methods": []
}
By adding a default scope with an "include", LoopBack will automatically embed the object(s) of the related model based on the named relation (just like if you added it in your query -- which as discussed, is not possible, or at least not easy, in this case).
One caveat: since Role and RoleMapping are built-in models and are surely marked as non-public, I am not actually sure whether you can include them directly (but for a different reason than above). I haven't worked enough with ACLs (yet), but presumably there's more complexity around access controls especially in related models.
So, whereas my example code above explain the mechanics of doing the include here, the policy concern may slow you down (I'd be curious to know if they do).
That said, however, I guess you could add a derived model (from RoleMapping) that you make public (just like you did for user), and use it instead everywhere (including in the relation to/from user) -- hopefully that's clear (let me know if not).
In conclusion: If you add a default scope to your derived user model, to do the include for you, the AngularJS service wrapper (built by lb-ng) will be none the wiser (the include all happens on the backend):
$scope.loginResult = User.login($scope.credentials,
function wasSuccessfulAuth(authResponse) {
console.log('Related models are here: ', authResponse.roles,
authResponse.user);
...
In other words, the resulting model will contain an array, .roles[], containing the related roles to this user (based on your relation definition), and .user with the entire user model right there!
This latter point is unclear but I'm confident in that, because I did exactly the above but with a different related model that I know works. And to my surprise, user was included as well, since that's explicitly requested by the LoopBack $resource wrapper (the one created by lb-ng). So, in fact, you don't have do a separate query to get the user -- it's already there! There's no API that I see when using the $service wrapper, to get at that built-in include and change it; I guess that's what was posted in a comment above.
Hope this is helpful.

User.login returns AccessToken instance. To get user role, you should make separate request to fetch user, including role.
