Save user input (string) in Watson assistant - ibm-cloud

I'm building a chat-bot application based on IBM Watson. I need to save the user input into a variable.
I searched the web and I only found tutorials where the input must be of entity sys-(number, day, time, location, person).
In my dialog I ask the user about his identifier. This identifier should be an alphanumerical string.
How can I do so?

User input can be accessed as a String by this expression: <?input.text?>

Take a look at this IBM Cloud solution tutorial that creates a chatbot. It uses identifiers for emails, URIs and conferences.
I see two options for your case:
Define an entity type "identifier" and use a pattern in its definition. The pattern would be the alphanumerical regular expression. For a slot, assign the entity of "identifier" as necessary input.
Use the value of the input variable. Thereafter, extract the identifier by applying string methods.
To access the actual value in a detected entity, use the value property. See the Watson Assistant docs on entity properties for the full syntax and examples.

How to access Method Names from source object in Rule Definition

In our implementation of the Rules Engine we have a test form similar to Rule Test Form on the online demo on "Business Rules Engine Demo". What we would like to do is conditionally show only the Test Fields for the items in use in the rule. We are doing this by grabbing the rule.definition JSON from the ruleeditor then look for the items which we can conditionally create using AngularJS's ng-if directive. This works great with Fields. If the user selects a method, our method of parsing the string is failing. What it appears is the Field Names are stored in the JSON as plain text however the Method Names are not. Is there a way we can configure the control to either A not encrypt the method names or is there a way that we can tap into the encryption to identify if a method is in use in our rule? Thanks in advance.
Methods and actions can have overloads which the Code Effects rule editor supports. Therefore, we can't have multiple menu entries with the same name. Instead, we use a signature hash on all in-rule methods and rule actions regardless of whether it has an overload or not to make them unique on the client.
You need to have either the Full Source or the Editor Source license in order to change the code to either stop that hashing, or tap into the process, or implement it your own way. You don't have that option with any other Code Effects perpetual license.

IBM Watson Assistant: Regular expressions with context variables

I am gathering some context variables with slots, and they work just fine.
So I decided to do in another node of the conversation, check if one of these context variables is a specific number:
I was thinking on enabling multi-responses and check if, for example $dni:1 (it is an integer, pattern of 1 integer only), or if it is 2 or 3:
But this is not working. I was trying to solve it for some days with different approaches but I really cannot find a way through it.
My guess is that a context variable has a value, and you can print it to use it like responding with the user's name and stuff like that (which indeed is useful!), but comparing values is not possible.
Any insights on this I can receive?
Watson Assistant uses a short-hand syntax but also supports the more complex expressions. What you could do is to edit the condition in the JSON editor. There, for the condition, use a function like matches() on the value of the context variable.
Note that it is not recommended to check for context variables in the slot conditions. You can use multi-responses. An alternative way is to put the check into the response itself. There, you can use predicates to generate the answer.
<? context.dni==1 ? 'Very well' : 'Your number is not 1' ?>
You can nest the evaluation to have three different answers. Another way is to build an array of responses and use dni as key.
Instead of matching to specific integers, you could consider using the Numbers system entity. Watson Assistant supports several languages. As a benefit, users could answer "the first one", "the 2nd option", etc., and the bot still would understand and your logic could still route to the correct answer.

How to call google map api using swift 4?

My issue is a, I need only restaurant, bar using google API.
If you need code i'm send you.
this is my base url:- "https://maps.googleapis.com/maps/api/place/"
nearbyURLFragment :- let nearbyURLFragment = "nearbysearch/json?key=%#&location=%f,%f&rankby=distance&type=restaurant,bar"
a single type of proper working.
but here is I'm not getting a proper result.
Quoting the Google API Docs,
Restricts the results to places matching the specified type. Only one
type may be specified (if more than one type is provided, all types
following the first entry are ignored).
The only workaround of this would be to define one in the keyword attribute however this will return very inconsistent results.
The best way to do this is to do two separate API calls with differing types.

DialogFlow: Alphanumeric (fixed length) parameter in Intents and #sys.any type

I have an intent in DialogFlow that accepts an input/parameter from the user for validation purposes. The parameter is of fixed length and is alphanumberic (e.g. ABC1234). It is a random ID different for different users. The data input is validated at the backend using a webhook call.
In order for the input value to be accepted, I have to set the type of the parameter as #sys.any. It does work and the value is passed through to webhook for validation. But since this intent has no "Input contexts", the next intents are never triggered because each input from the user is evaluated to#sys.any.
What I need is a type that accepts custom value. But I can't find any.
Here is screenshot for the intent:
Also note that the next intent that doesn't get triggered has the "In context" = authentication
And user says expressions like book me. Due to #sys.any in the intent above, book me causes the above intent to trigger.
This question has similar requirements but no answers: DialogFlow - Improve entity/parameter recognition for alphanumeric parameters
Also: https://discuss.api.ai/t/alphanumeric-support/2572
So after some digging, I had to change the approach. That is, #sys.any is not the way to go. Instead of alpha-numeric, I opted to use the numeric part of the input param (last four digits) and handled any duplication at the server end/webhook. The type I used instead is #sys.number-sequence.
I still had to handle the contexts in a way that any input of number-sequence doesn't trigger this intent.
This is not possible on Dialogflow. You can achieve that in your webhook with a regular expression for example.

API.AI Intent won't save when adding Required Action

I'm trying to create a chat bot that will help users search up motorcycles.
I'm new to API.AI and have set up my entities and their synonyms, my intent and user expressions, as well as references to the entities (#engineSize, #make, #bikeType).
My problem is when I try to add a required action and prompt, and then try to save the intent, I get the following message:
"The following entities reference each other and form an infinite loop: [engineSize]."
Initially I thought I was using the references wrong in the user expressions. I deleted every reference except for one expression which uses all three entities.
I can't figure out what I'm doing wrong. Any help would be greatly appreciated, thanks! Pix below for further details.
EDIT: I fixed one of the issues of trying to pass a template expression as an example. However, I still get the same error message. I will replace and update my image links to include the edits.
Annotated User expressions
Required Actions
Interestingly enough, the answer to this post would have been difficult to find because the problem was in defining my entities.
In the entity definitions, I included an #ref to the entity itself. ie the bikeType entity contained #bikeType as one of its definitions.
This is not to be mistaken with the User Expressions. As long as the user expression is marked as a Template (the entire line is denoted with an '#' on the far left, as opposed to a large " ), there should be no issues.
Edited for clarity to get at root problem
In the provided user input examples you give the intent, you are supposed to provide general examples and then highlight any text belonging to an entity to map where entities appear in user's inquiries.
In your case, you have input the actual entity reference '#engineSize' as an example belonging to the engineSize entity, creating a self reference.
A proper provided user example would look like:
Also note though that if you are just using entities to store generic information like numbers, addresses, times, etc. it generally makes far more sense to use prebuilt system entities for those categories than create a custom entity, for example #sys.number-integer might be exactly what you need
It looks like you need to get a firmer understanding of entities, for which I would recommend the documentation:
