I'm trying to make an inline Telegram bot that would modify user input in a certain way. Because of that I wanted to answer the query with simple text, but that doesn't seem possible and I'm wondering if it's really not or I'm missing something.
According to Telegram, there's 20 handy result types, yet there doesn't seem to be simple plain text. Is that really the case? How can I achieve my desired result then?
I had the same exact issue and solved it with the InlineQueryResultArticle.
Example code for your OnInlineQuery Method:
// Check for invalid queries
if (e.InlineQuery.Query == null)
return;
if (e.InlineQuery.Query == "")
return;
InlineQueryResultBase[] results = {
new InlineQueryResultArticle(
// id's should be unique for each type of response
id: "1",
// Title of the option
title: "sample title",
// This is what is returned
new InputTextMessageContent("text that is returned") {ParseMode = Telegram.Bot.Types.Enums.ParseMode.Default })
{
// This is just the description shown for the option
Description = "You could also put your output text for a preview here too."
}
};
// Send the response
try
{
// If your method is not async you have to remove the await
await client.AnswerInlineQueryAsync(e.InlineQuery.Id, results);
}
catch (Exception ex)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine($"Error responding to Inline Query! {ex.Message}");
}
Use "InlineQueryResultArticle" and either set the value of "url" to undefined or do not set "url" fileld.

I need some help to figure it our why I am getting error when using macthes API, this is my code:
export async function searchCars(query) {
await connect();
const repository = client.fetchRepository(schema);
const cars = await repository
.search()
.where("make")
.eq(query)
.or("model")
.eq(query)
.or("description")
.matches(query)
.return.all();
return cars;
}
And I am getting this error when making API request
May I ask for help?
Many thanks ~~
I did remove the macthes() API, the whole query works, and I can get results back.
If i add it back, the APi will return redis error ...
Expectation: I would like to do text search which matches the paragraph text, then return the record(s).
Sorry, I think I have figured it our, the issue is we need to ensure the scheme field type must be text rather than string, something like below:
description: { type: "text", textSearch: true },
I am new to flutter and I am sure there is a simple way of doing this. Let me first give you a background. I have 2 tables(collections). The first one store a mapping. Therefore it returns a key based on an id which will be used to query the second table and retrieve the data from firebase.
I have written 2 data models and 2 functions which return Future<> data. They are as follows-
Future<SpecificDevice> getSpecificDevice(String deviceId) {
Future<SpecificDevice> obj =_database.reference().child("deviceMapping").orderByChild("deviceId").equalTo(deviceId).once().then((snapshot) {
SpecificDevice specificDevice = new SpecificDevice(deviceId, "XXXX", new List<String> ());
if(snapshot.value.isNotEmpty){
print(snapshot.value);
snapshot.value.forEach((key,values) {
if(values["deviceId"] == deviceId) {
specificDevice.deviceKey = values["deviceDesc"];
specificDevice.vendorList = List.from(values["vendorList"]);
}
});
}
return specificDevice;
});
return obj;
}
This function gets the mapping deviceId -> deviceKey.
This is the key of record stored in another table. Following is the function for it.
Future<Device> getDeviceDescription(String deviceKey) {
Future<Device> device = _database.reference().child("deviceDescription").once().then((snapshot) {
Device deviceObj = new Device("YYYY", "YYYY", "YYY", "YYYY", "YYYY");
if(snapshot.value.isNotEmpty){
print(snapshot.value);
//Future<SpecificDevice> obj = getSpecificDevice(deviceId);
//obj.then((value) {
snapshot.value.forEach((key,values) {
if(key == deviceKey) { // compare with value.deviceKey instead
print(values["deviceDescription"]); // I get the correct data here.
deviceObj.manual = values["deviceManual"];
deviceObj.deviceType = values["deviceType"];
deviceObj.description = values["deviceDescription"];
deviceObj.brand = values["deviceBrand"];
deviceObj.picture = values["devicePicture"];
}
// });
});
}
return deviceObj;
});
return device;
}
Now both of these functions work. I want to make it work one after the other. In the above function, if I uncomment the lines of code, the data is retrieved properly in the inner function but it returns initial default values set because the values get returned before setting the obj of SpecificDevice.
Here is where I am getting the error. I am calling the second function in FutureBuilder<> code with the above lines uncommented and taking input param as deviceId.
return FutureBuilder<Device>(
future: getDeviceDescription(deviceId),
builder:(BuildContext context,AsyncSnapshot snapshot){... // using snapshot.data in its child.
Here in snapshot.data. would give me YYYY. But it should get me the value from the database.
I am stuck with this for a while. Any help in fixing this? or if what I am trying to do is clear then please suggest me a better way to approach this. Thanks in advance!
The answer is rather simple:
first and foremost - you forgot to use async / await keywords, which will guarantee synchronous data retrieval from the database. Always use them, if you are connecting to any network service
to make one command work after another - use .then((value) {}). It will get data from the first function (which you pass using return) and use it in the second function.
Solved the problem by changing the calling function to -
return FutureBuilder<Device>(
future: getSpecificDevice(deviceId).then((value){
return getDeviceDescription(value.deviceKey);
}),
builder:(BuildContext context,AsyncSnapshot snapshot){
Authenticate with Firebase with a Phone Number (JS) requires a mandatory reCAPTCHA verifier, it takes the ID of the container. For the ID of the container, I am generating a random one -
firebase_recaptcha_container: "recaptcha-container",
firebase_recaptcha_reset: function() {
if (typeof appVerifier != "undefined") {
appVerifier.reset()
appVerifier.clear()
}
let id = loadJS.firebase_recaptcha_container
let newID = loadJS.randomString(10)
$("#"+id).contents().remove()
$("#"+id).prop("id", newID)
loadJS.firebase_recaptcha_container = newID
return newID
}
then requesting for the RecaptchaVerifier and upon receiving I set this as a global variable window.appVerifier .
firebase_recaptcha: function(name_r="default") {
let promiseD = new firebase.auth.RecaptchaVerifier(name_r, {
'size': 'invisible',
'callback': function(response) {
resolve(response)
},
'expired-callback': function(r) {
console.log("expired", r)
},
'isolated' : false
});
return promiseD
},

let container_recaptcha = $utils.firebase_recaptcha_reset()
window.appVerifier = await $utils.firebase_recaptcha(container_recaptcha)
It works totally fine for the very first time. But its a honest mistake for users not to use correct phone number. So for next time, I am doing the same thing again and getting error while generating the RecaptchaVerifier -
reCAPTCHA has already been rendered in this element
Which sadly does not make sense as the new element is totally different and also clear, reset methods were called following the documentation. I am neither using any other reCaptcha on this page. Refreshing the page might be a possible solution but that I really hate. Any insight would be helpful.
Thanks!
Finally found the solution, looks like it was a stupid mistake!
Invoking firebase.auth.RecaptchaVerifier adds new recaptcha scripts, every time! Hence all needed to be done is, calling it once, it does the rest on its own.
This won't get fixed just by implementing recaptchaVerifier.clear() method.
In the callback where you are passing this appVerifier, you'll have to implement the above clear method and add that "recaptcha-container" using ref
The below would be the element in render method:
<div ref={recaptchaWrapperRef}>
<div id="recaptcha-container"></div>
</div>
GenerateCaptcha function:
const generateRecaptcha = () => {
appVerifier = new RecaptchaVerifier(
"recaptcha-container",
{
size: "invisible",
},
authentication
);
Inside submit Callback:
if (appVerifier && recaptchaWrapperRef.current) {
appVerifier.clear();
recaptchaWrapperRef.current.innerHTML = `<div id="recaptcha-container"></div>`;
}
// Initialize new reCaptcha verifier
generateRecaptcha();
Hi i have a noSql db in firebase.
I want to get the object where userId is 288
i'v tried many combinations but i cant figure out how its done.
This is my code so far :
var refTest= database.ref('conversation')
var query = refTest
.orderByChild('messages');
query.on('value', function(data) {
var a = data.val();
console.log(a.messages.userId);
console.log(data.val());
});
This is a image of my "schema"
I'm obviously a noob when it comes to NoSQL. I do understand SQL
All help is appreciated
You can order/filter on a nested value like this:
var refTest= database.ref('conversation')
var query = refTest.orderByChild('messages/userId').equalTo("288");
query.on('value', function(snapshot) {
snapshot.forEach(function(child) {
console.log(child.key);
console.log(child.val());
});
});
The forEach is needed, since there may be multiple child nodes with messages/userId equal to 288.
The key named "messages" doesn't make sense in your schema. Because if you want to have another message under that conversation, then you wouldn't be able to add it with the same key name and you also couldn't add it under "messages" because it would overwrite the other one. My suggestion is to use the push() method for adding a new message. This way you uniquely identify each message.
Regarding your question, an easy to understand way of parsing your schema is this: you loop through each message of each conversation for finding the messages with userID.
refTest.on('value', function(data) {
var conversations = data.val();
for (conversation in conversations){
for (message in conversation) {
if (message.userId == 288) {
// do whatever you need
// and eventually return something to break the loops
}
}
}
}
Of course, you can adapt it based on your needs
hope my first question here is not a stupid one.
Lets say we want to build a chat application with meteor, with logedin and anonymous users. The chat should be filled like that:
var post = {
userId: user._id, // is empty if anonymous user
submitted: new Date().getTime(),
text: chat_message
});
var postId = Posts.insert(post);
The publication could looks like this to make sure that the userId is not transfered
Meteor.publish('getTheChat', function() {
return Post.find({}, {fields: {userId: false});
});
But is there a way to add a field in the returned collection dynamically?
The userId should not be published but a status like "Your_Post","another_logedin_user" or "an_anonymous_user". By having that, I could include some css, so the chat looks a little bit more like WhatsApp or iMessage.
The logic inside the publish method could be something like
if (userId == this.userId) {
status = "Your_Post";
} else if (userId != null) {
status = "another_logedin_user";
} else {
status = "an_anonymous_user";
}
You see, the publication should include different values when called from different users. Is there a way in Meteor.publish?
Thanks for any insight or suggestions
Thank you both for your ideas! But as I had to find out (just for my inward peace) how it is possible inside the publish method server sided, I came, with the help of David's link, to this solution -maybe it will help someone later:
Meteor.publish('getTheChat', function(postId) {
var currentUserId = this.userId;
var ownerUserId = Posts.findOne({'_id':postId}).userId;
var findOptions = {}; // in my final coding these differ for 'chat room owners' and 'normal users'
var transform = function(post) {
if (currentUserId && post.userId == currentUserId) {
post.userId = "posted by you";
} else if (post.userId == null) {
post.userId = "anonym posted";
} else if (post.userId == ownerUserId) {
post.userId = "posted by owner";
} else {
post.userID = "posted by another loged in";
return post;
};
var self = this;
var handle = Posts.find(findOptions).observe({
added: function (document) {
self.added('posts', document._id, transform(document));
},
changed: function (newDocument, oldDocument) {
self.changed('posts', document._id, transform(newDocument));
},
removed: function (oldDocument) {
self.removed('posts', oldDocument._id);
}
});
self.ready();
self.onStop(function(){
handle.stop();
});
By having this I am finally able to overwrite values dynamically.
It looks like you need to add a transform on your Posts collection. You can do this in your publish function (as seen here), but server-side transforms are computationally inefficient and tricky to write. Though they are necessary in cases where only the server could perform the action - e.g. signed URLs. In your case, I'd recommend a standard collection transform which is a filter applied after the documents are fetched.
Unfortunately, this kind of transform would require the userId on the client. I've never seen a case where simply publishing a id could cause a security issue. If you believe this is the case with your app, I'm very interested to know why. If you can overcome this restriction, keep reading...
You can read about transforms in the documentation on collections, and you can see an example on evented mind. Personally I like to use the collection-helpers package for this.
If you try collection-helpers, your transform could look like:
Posts.helpers({
status: function() {
if (this.userId === Meteor.userId()) {
return 'Your_Post';
} else if (this.userId != null) {
return 'another_logedin_user';
} else {
return 'an_anonymous_user';
}
}
});
And then you could use it in your template like:
{{#each posts}}
<p>{{text}} - <span class='status'>{{status}}</span></p>
{{/each}}
Of course, you can also use template helpers to achieve the same result but transforms are more easily reusable across your application.
Sadly, this has been a huge issue for me too, and I am sorry to say, it is not technically possible to just add a field on the publisher's query and use it conveniently in your view. BUT, I have a solution that may work for you. It will also give you an idea of how complex it can become as soon as you want to keep some reactive data private in Meteor.
Server side:
First, create two different publishers: one for the current user's posts, one for all the others:
Meteor.publish('getTheOthersChat', function() {
return Post.find({$ne:{userId: this.userId}}, {fields: {userId: false});
});
Meteor.publish('getTheOwnChat', function() {
return Post.find({userId: this.userId});
});
Client/router side:
Then, subscribe to both of these: what this will do is include the post's userId only when it is the own user's id. If not, it'll be undefined.
Then, we still need to identify the case "anonymously posted" vs "posted by user". For this, you can add another field during the post creation, for example is_anonymous, which you then set to true or false depending on the case if the user is logged in or not. The check would then be:
if (userId) {
status = "Your_Post";
} else if (is_anonymous === false) {
status = "another_logedin_user";
} else {
status = "an_anonymous_user";
}
This solution should work. I know, it is sad to have to come to this kind of means. It makes Meteor look clunky and impractical for tasks that should be dead easy. Such a shame for such a cool framework!
