I'm trying to setup a simple messaging system between two users, x and y.
x views domain.com/user/:_id (where_id is user y)
x clicks message
x goes to domain.com/message/:_id (where _id is for the message thread if exists in messageCollection - query where to:user y's id and from:user x's id)
else
x goes to domain.com/message/newMessage
the newMessage is where I would like to pass user y's id, but preferable without a url param.
Is this possible through iron-router? Also, would this be the best design to do something like a private message in meteor.
Thanks
You can use a global variable for this. For example, before you route the user to the newMessage-page, set newMessageReceiverId = 'user_y_id'. I don't think Iron-Router has support for this ( I can't see the reason you want to avoid it).

I've been trying to solve this for three days and none pf the solutions I've found online seem to work, so I am going to have to ask for help.
I want to create a Telegram "Group Chat" to be used by members of a club I'm in. I created the chat named with the initials of the club, like: "ABCD" and added some members. Now I want to automate the sending of occasional messages to the group for all members to see. Weather forecast, random photograph from our gallery, etc.
Using #BotFather I created a bot called "ABCDbot" and noted the token for that bot. Now I have two "ABCD"s on my browser left side-panel. Selecting one gives me "ABCD bot" and selecting the other gives me "ABCD 123 members".
Using a perl script and LWP I can send a photo using
#!/usr/bin/perl -w
use feature 'say';
use LWP;
my $api = LWP::UserAgent->new ();
my $chat_id = '1234567890';
my $photo = '/home/user/gallery/photo999.jpg';
my $response = $api->post(
"https://api.telegram.org/bot<ABCDbot's token>/sendPhoto",
[ 'chat_id' => $chat_id,
'caption' => 'Photo Randomly Selected by the gallery',
'photo' => $photo,
],
'Content_Type' => 'form-data',
);
if ($response->is_success) {
say "Response..... Success!";
} else {
say "Response..... Failure!";
}
This works, providing I give it a legitimate chat_id and a legitimate file to send.
But the trouble is: I can't find the chat_id for the group chat with 123 members! Every method I've tried now proves to be obsolete or simply doesn't return the desired chat_id for the ABCD group chat. I can get my own chat ID or that of individual members of the group, or of the bot itself, and can successfully send photos, messages, etc to those destinations, but I just can't send anything to the group.
Can anybody walk me through the process of getting the chat_id for my group chat? Or direct me to a document describing an up-to-date, working method for obtaining same?
Assistance much appreciated.
Method 1 (WebZ)
This is based on JayeshRocks's question with some extra steps to make the ID work with Bot API. Thanks to him first.
Login to Telegram WebZ.
Open the chat you want to get its ID.
Your browser's address should look like https://web.telegram.org/z/#-1527776602.
Remove the protocol, domain and path keeping the anchor so your result looks like #-1527776602.
Replace "#-" with "-100" so it looks like -1001527776602.
You can now use your final result which should look like -1001527776602.
Method 2 (Private Supergroups)
If the chat is a private channel/supergroup, you can do the following:
Copy a link of a message. (It will look like https://t.me/c/1527776602/1002.)
Remove the protocol and domain name, so it looks like c/1527776602/1002.
Remove the first and last path, so it looks like 1527776602.
Append "-100" to the beginning of the result, so it looks like -1001527776602.
You can now use your final result which looks like -1001527776602.
Method 3 (Third-Party Bots)
If you trust 3rd party bots, there are many of them. A known one is #MissRose_bot which you can add it to your group and use its /id command. Another one is #usinfobot which works inline and only for public chats.
To get a telegram group ID you need to open the group on https://web.telegram.org/z/ when you do so click on the group you want to gain the ID of then if you look at the URL it will say something like https://web.telegram.org/z/#-1234567 and the numbers there is the ID of the telegram group!
Hope this helps
I'm working with the SAFE stack (https://safe-stack.github.io/) and through the example dojo. It's great so far.
I'd like to extend the example to include a button to login/auth via Google. So I looked at an example on the Google website (https://developers.google.com/identity/sign-in/web/build-button). And then I had a look how to do authentication using ASP.NET (https://learn.microsoft.com/en-us/aspnet/core/security/authentication/social/google-logins?view=aspnetcore-2.1&tabs=aspnetcore2x) As a result I ended up confused as to how to integrate this into a SAFE project. Can someone tell me what they would do? SHould I be trying to use ASP.NET Identity or should I be using the JWT approach? I don't even know if they are the same since I'm very new to web frameworks.....
The other question I have is how would one inject raw Javascript into the client side of a SAFE project. The google example above shows raw JS/CSS/HTML code? Should I be injecting that as is or should I look in React for some button that does this and map that idea back through Fable?
Setting up OAuth
The easiest way to use Google OAuth is to wait until the next release of Saturn, at which point Saturn will include the use_google_oauth feature that I just added. :-) See the source code if you're interested in how it works, though I'm afraid you can't implement this yourself with use_custom_oauth because you'll run into a type error (the underlying ASP.NET code has a GoogleOptions class, and use_custom_oauth wants an OAuthOptions class, and they aren't compatible).
To use it, add the following to your application CE:
use_google_oauth googleClientId googleClientSecret "/oauth_callback_google" []
The last parameter should be a sequence of string * string pairs that represent keys and values: you could use a list of tuples, or a Map passed through Map.toSeq, or whatever. The keys of that sequence are keys in the JSON structure that Google returns for the "get more details about this person" API call, and the values are the claim types that those keys should be mapped to in ASP.NET's claims system. The default mapping that use_google_oauth already does is:
id → ClaimTypes.NameIdentifier
displayName → ClaimTypes.Name
emails[] (see note) → ClaimTypes.Email
Those three are automatically mapped by ASP.NET. I added a fourth mapping:
avatar.url → `"urn:google:avatar:url"
There's no standard ClaimTypes name for this one, so I picked an arbitrary URN. Caution: this feature hasn't been released yet, and it's possible (though unlikely) that this string might change between now and when the feature is released in the next version of Saturn.
With those four claim types mapped automatically, I found that I didn't need to specify any additional claims, so I left the final parameter to use_google_oauth as an empty list in my demo app. But if you want more (say you want to get the user's preferred language to use in your localization) then just add them to that list, e.g.:
use_google_oauth googleClientId googleClientSecret "/oauth_callback_google" ["language", "urn:google:language"]
And then once someone has logged in, look in the User.Claims seq for a claim of type "urn:google:language".
Note re: the emails[] list in the JSON: I haven't tested this with a Google account that has multiple emails, so I don't know how ASP.NET picks an email to put in the ClaimTypes.Email claim. It might just pick the first email in the list, or it might pick the one with a type of account; I just don't know. Some experimentation might be needed.
Also note that third-party OAuth, including GitHub and Google, has been split into a new Saturn.Extensions.Authorization package. It will be released on NuGet at the same time that Saturn's next version (probably 0.7.0) is released.
Making the button
Once you have the use_google_oauth call in your application, create something like the following:
let googleUserIdForRmunn = "106310971773596475579"
let matchUpUsers : HttpHandler = fun next ctx ->
// A real implementation would match up user identities with something stored in a database, not hardcoded in Users.fs like this example
let isRmunn =
ctx.User.Claims |> Seq.exists (fun claim ->
claim.Issuer = "Google" && claim.Type = ClaimTypes.NameIdentifier && claim.Value = googleUserIdForRmunn)
if isRmunn then
printfn "User rmunn is an admin of this demo app, adding admin role to user claims"
ctx.User.AddIdentity(new ClaimsIdentity([Claim(ClaimTypes.Role, "Admin", ClaimValueTypes.String, "MyApplication")]))
next ctx
let loggedIn = pipeline {
requires_authentication (Giraffe.Auth.challenge "Google")
plug matchUpUsers
}
let isAdmin = pipeline {
plug loggedIn
requires_role "Admin" (RequestErrors.forbidden (text "Must be admin"))
}
And now in your scope (NOTE: "scope" will probably be renamed to "router" in Saturn 0.7.0), do something like this:
let loggedInView = scope {
pipe_through loggedIn
get "/" (htmlView Index.layout)
get "/index.html" (redirectTo false "/")
get "/default.html" (redirectTo false "/")
get "/admin" (isAdmin >=> htmlView AdminPage.layout)
}
And finally, let your main router have a URL that passes things to the loggedInView router:
let browserRouter = scope {
not_found_handler (htmlView NotFound.layout) //Use the default 404 webpage
pipe_through browser //Use the default browser pipeline
forward "" defaultView //Use the default view
forward "/members-only" loggedInView
}
Then your login button can just go to the /members-only route and you'll be fine.
Note that if you want multiple OAuth buttons (Google, GitHub, Facebook, etc) you'll probably need to tweak that a bit, but this answer is long enough already. When you get to the point of wanting multiple OAuth buttons, go ahead and ask another question.
I want to build a realtime quiz game which randomly matches two players (according to their winning rate if they are logged in). I've read through the book Discover Meteor and have a basic understanding of the framework, but I just have no idea of how to implement the matching part. Anyone know how to do that?
if you want to match users who have scores close to each other, you can do something like this : mongodb - Find document with closest integer value
The Meteor code for those Mongo queries is very similar, but there are some subtle differences that are kind of tricky. In Meteor, it would look something like this :
SP // "selected player" = the User you want to match someone up with
var score = SP.score; // selected player's score
var queryLow = {score: {$lte:score},_id:{$ne:SP._id}};
var queryHigh = {score:{$gte:score},_id:{$ne:SP._id}};
// "L" is the player with the closest lower score
var L=Players.findOne(queryLow,{sort:{score:-1},limit:1});
// "H" is the player with the closest higher score
var H=Players.findOne(queryHigh,{sort:{score:1},limit:1});
so, now you have references to the players with scores right above and right below the 'selected player'. In terms of making it random, perhaps start with a simple algorithm like "match me with the next available player who's score is closest" , then if it's too predictable and boring you can throw some randomness into the algorithm.
you can view the above Meteor code working live here http://meteorpad.com/pad/4umMP4iY8AkB9ct2d/ClosestScore
and you can Fork it and mess about with the queries to see how it works.
good luck! Meteor is great, I really like it.
If you add the package peppelg:random-opponent-matcher to your application, you can match together opponents like this:
On the server, you need to have an instance of RandomOpponentMatcher like this:
new RandomOpponentMatcher('my-matcher', {name: 'fifo'}, function(user1, user2){
// Create the match/game they should play.
})
The function you pass to RandomOpponentMatcher will get called when two users been matched to play against each other. In it, you'll probably want to create the match the users should play against each other (this package does only match opponents together, it does not contain any functionality for playing games/matches).
On the client, you need to create an instance of RandomOpponentMatcher as well, but you only pass the name to it (the same name as you used on the server):
myMatcher = new RandomOpponentMatcher('my-matcher')
Then when the users is logged in and which to be matched with a random opponent, all you need to do is to call the add method. For example:
<template name="myTemplate">
<button class="clickMatchesWithOpponent">Match me with someone!</button>
</template>
Template.myTemplate.events({
'click .clickMatchesWithOpponent': function(event, template){
myMatcher.add()
}
})
When two different logged in users has clicked on the button, the function you passed to RandomOpponentMatcher on the server will get called.
One implementation might be as follows:
A user somehow triggers a 'looking for game' event that sets an attribute on user.profile.lookingForGame to true. The event then makes a call to a server side Meteor method which queries for all other online users looking for games.
From there you it really depends on how you want to handle users once they 'match'.
To determine all online users, try using the User Status package:
https://github.com/mizzao/meteor-user-status
Once added, any online user will have an attribute in the profile object of 'online'. You can use this to query for all online users.
I am using linked-in j library.
I am able to connect with linked-in but when i go for details for the profile of current user then i get whole Person object but this object only contain the values of first name, last name and headline.And other values are null.
But when i go to my linked-in public profile their i can see the skills, college etc.
My application have full access.
I think you never set ProfileField's in enum
Please try like this,
Set<ProfileField> propertiesToFetch = EnumSet.of(ProfileField.ID,
ProfileField.FIRST_NAME, ProfileField.LAST_NAME,
ProfileField.HEADLINE, ProfileField.PICTURE_URL,
ProfileField.DATE_OF_BIRTH, ProfileField.PHONE_NUMBERS,
ProfileField.MAIN_ADDRESS, ProfileField.INDUSTRY,
ProfileField.EDUCATIONS, ProfileField.LANGUAGES_LANGUAGE_NAME,
ProfileField.SKILLS_SKILL_NAME,
ProfileField.CERTIFICATIONS_NAME, ProfileField.POSITIONS_TITLE,
ProfileField.POSITIONS_COMPANY_NAME,
ProfileField.POSITIONS_COMPANY);
Person profile = client.getProfileForCurrentUser(propertiesToFetch);
I am designing an infopath (Change Request) form:
1)How can i add a text box that automaticaly increments to the next number when a new form is created (adding a new Change Request form to the form library).
2)How do i retrieve information from an existing form to the new form.
NOTE: The field is not inside a repeating table. I need to generate the next Change Request number on each new Change Request form.
TIA!
There is no build-in way to do this, but there are several ways to achieve what you want (Database query or SPList query). But this kind of request somehow smells like a workaround for an other problem.
Common cases for increasing numbers are:
unique IDs
count the Requests
make referable by external list (same as ID)
make IDs guessable (time stamps are not)
If you need an ID: In most cases you are not forced to use integer IDs. Simply use the form title as a natural ID. (e.g. customer + timestamp)
If you need guessable IDs, you need them because an external system wants to access or refer to the request. In that case try to change the pull-direction into a push-direction (e.g. by using workflows) or let your other system provide a "getID" function that can be called by your form to obtain a known ID (no guessing needed).
Anyway - for me, it looks like you want to achieve this to solve some other problem. Maybe there are different solutions for that problem too?
You could enter a token in your text-titles on the form where you want autonumbering, such as #num#, and then use javascript or jquery to find those tokens and replace them with incremented numbers.
The drawback to this is that if you exported the list to excel, the tokens would not get translated to numbers. But it is a good solution for on-screen rendering.
Use Firebug to figure out the class of the container housing your autonumber tags.
Maybe you could do something like this:
function TokenReplacement(){
var ClassName = 'ms-formlabel';
var elements = new Array();
var elements = document.getElementsByTagName('td');
var numerator=0;
//Now do find and replace on everything else
for(var e=0;e<elements.length;e++){
thiselement = elements[e];
if(thiselement.className == ClassName){
//autonumber the questions by replacing the #num# token
if(thiselement.innerHTML.search('#num#') > -1){
numerator++
var replacenum = "<b>" + numerator + ". </b>";
thiselement.innerHTML = elements[e].innerHTML.replace('#num#',replacenum);
}
}
}
}
