I am trying to create a group chat using the JavaScript SDK, I have registered and configured the authkey etc
Where do I specify the Room JID so that the user will be connected to a particular public room?
Create a group and join the users:
QB.chat.dialog.create({type: 1, occupants_ids: '56,558,12334', name: 'Chat with Bob, Sam, Garry'}, onDialogCreated);
Type = 1, indicate that the dialog is a public group.
Join users after create the group
var dialog_id = '53aac0cd535c12b50600962c';
QB.chat.dialog.update(dialog_id, {name: 'Chat with Garry and John', pull_all: {occupants_ids: [22]}}, onDialogUpdated);
If you want to make it in the user session. To join the group
QB.chat.muc.join(jid, function() {
// callback function
});
QB.chat.muc.leave(jid, function() {
// callback function
});

I'm just learning FaunaDB and FQL and having some trouble (mainly because I come from MySQL). I can successfully query a table (eg: users) and fetch a specific user. This user has a property users.expiry_date which is a faunadb Time() type.
What I would like to do is know if this date has expired by using the function LT(Now(), users.expiry_date), but I don't know how to create this query. Do I have to create an Index first?
So in short, just fetching one of the users documents gets me this:
{
id: 1,
username: 'test',
expiry_date: Time("2022-01-10T16:01:47.394Z")
}
But I would like to get this:
{
id: 1,
username: 'test',
expiry_date: Time("2022-01-10T16:01:47.394Z"),
has_expired: true,
}
I have this FQL query now (ignore oauthInfo):
Query(
Let(
{
oauthInfo: Select(['data'], Get(Ref(Collection('user_oauth_info'), refId))),
user: Select(['data'], Get(Select(['user_id'], Var('oauthInfo'))))
},
Merge({ oauthInfo: Var('oauthInfo') }, { user: Var('user') })
)
)
How would I do the equivalent of the mySQL query SELECT users.*, IF(users.expiry_date < NOW(), 1, 0) as is_expired FROM users in FQL?
Your use of Let and Merge show that you are thinking about FQL in a good way. These are functions that can go a long way to making your queries more organized and readable!
I will start with some notes, but they will be relevant to the final answer, so please stick with me.
The Query function
https://docs.fauna.com/fauna/current/api/fql/functions/query
First, you should not need to wrap anything in the Query function, here. Query is necessary for defining functions in FQL that will be run later, for example, in the User-Defined Function body. You will always see it as Query(Lambda(...)).
Fauna IDs
https://docs.fauna.com/fauna/current/learn/understanding/documents
Remember that Fauna assigns unique IDs for every Document for you. When I see fields named id, that is a bit of a red flag, so I want to highlight that. There are plenty of reasons that you might store some business-ID in a Document, but be sure that you need it.
Getting an ID
A Document in Fauna is shaped like:
{
ref: Ref(Collection("users"), "101"), // <-- "id" is 101
ts: 1641508095450000,
data: { /* ... */ }
}
In the JS driver you can use this id by using documentResult.ref.id (other drivers can do this in similar ways)
You can access the ID directly in FQL as well. You use the Select function.
Let(
{
user: Get(Select(['user_id'], Var('oauthInfo')))
id: Select(["ref", "id"], Var("user"))
},
Var("id")
)
More about the Select function.
https://docs.fauna.com/fauna/current/api/fql/functions/select
You are already using Select and that's the function you are looking for. It's what you use to grab any piece of an object or array.
Here's a contrived example that gets the zip code for the 3rd user in the Collection:
Let(
{
page: Paginate(Documents(Collection("user")),
},
Select(["data", 2, "data", "address", "zip"], Var("user"))
)
Bring it together
That said, your Let function is a great start. Let's break things down into smaller steps.
Let(
{
oauthInfo_ref: Ref(Collection('user_oauth_info'), refId)
oauthInfo_doc: Get(Var("oathInfoRef")),
// make sure that user_oath_info.user_id is a full Ref, not just a number
user_ref: Select(["data", "user_id"], Var("oauthInfo_doc"))
user_doc: Get(Var("user_ref")),
user_id: Select("id", Var("user_ref")),
// calculate expired
expiry_date: Select(["data", "expiry_date"], Var("user_doc")),
has_expired: LT(Now(), Var("expiry_date"))
},
// if the data does not overlap, Merge is not required.
// you can build plain objects in FQL
{
oauthInfo: Var("oauthInfo_doc"), // entire Document
user: Var("user_doc"), // entire Document
has_expired: Var("has_expired") // an extra field
}
)
Instead of returning the auth info and user as separate points if you do want to Merge them and/or add additional fields, then feel free to do that
// ...
Merge(
Select("data", Var("user_doc")), // just the data
{
user_id: Var("user_id"), // added field
has_expired: Var("has_expired") // added field
}
)
)
Hello great people of SO!
I hope you all have a good day and have a good health
Note: I'm not good at SQL
Sorry for bad english, but I will try my best to explain my issue
I'm using Laravel v8.x for my app, and after setting up model relationships, events, queues, etc, now I'm working for SQL
ATM, I have 2 Models,
User
Post
Relationships:
User hasMany Post
User belongsToMany User (Block)
User belongsToMany User (Follow)
Post belongsTo User
Database:
5 record for User
2 record for Block
3 records for Post
Table: (Using faker)
users
[
{ id: 1, name: 'Jonathan Beatrice', username: 'kiana.fay', ... },
{ id: 2, name: 'Lacey Kirlin', username: 'kenna.turner', ... },
{ id: 3, name: 'Alexander Schiller', username: 'cassandra95', ... },
{ id: 4, name: 'Daniel Wickozky', username: 'nkoepp', ... },
{ id: 5, name: 'Maymie Lehner', username: 'frami.felton', ... }
]
block
[
{ id: 1, by_id: 1, to_id: 2 }, // User #1 block user #2
{ id: 2, by_id: 4, to_id: 1 } // User #4 block user #1
]
posts
[
{ id: 1, user_id: 2, body: 'Test post', ... },
{ id: 2, user_id: 5, body: 'Lorem ipsum dolor sit amet ...', ... },
{ id: 3, user_id: 4, body: 'ABCD festival soon! ...', ... },
]
Everything works fine and smooth
Now that I want to implement search system, I have a problem, since I'm not good with SQL
Here's my code
SearchController.php
use ...;
use ...;
...
public function posts(Request $request)
{
// For testing purpose
$user = User::with(['userBlocks', 'blocksUser'])->find(1);
// Get all id of user that $user block
// return [2]
$user_blocks = $user->userBlocks->pluck('pivot')->pluck('to_id')->toArray();
// Get all id of user that block $user
// return [4]
$blocks_user = $user->blocksUser->pluck('pivot')->pluck('by_id')->toArray();
// Merge all ids above (must be unique())
// return [2, 4]
$blocks = array_merge($user_blocks, $blocks_user);
// .../search?q=xxx
$query = $request->query('q');
$sql = Post::query();
// Search for posts that has `posts`.`body` LIKE ? ($query)
$sql->where('body', 'LIKE', "%$query%");
// This is where I got confused
$sql->orWhereHas('user', function ($post_user) use ($blocks, $query) {
$post_user
->whereNotIn('id', $blocks) // Exclude posts that has user and their id not in (x, x, x, x, ... ; $block variable above)
->where('name', 'LIKE', "%$query%") // Find user that has name LIKE ? ($query)
->orWhere('username', 'LIKE', "%$query%"); // or Find user that has username LIKE ? ($query)
});
$sql->orderBy('created_at', 'DESC');
$sql->with(['user']);
$posts = $sql->simplePaginate(10, ['*'], 'p');
return $posts;
}
I run the code, .../search?q=e
Note:
All users has alphabet E in their names
And also all posts has alphabet E in their body
We (as User #1), block User #2, and User #4, block us (User #1)
Result: Controller returned all posts
This is the query when I use DB::enableQueryLog() and DB::getQueryLog()
SELECT
*
FROM
`posts`
WHERE `body` LIKE ?
AND EXISTS
(SELECT
*
FROM
`users`
WHERE `posts`.`user_id` = `users`.`id`
AND (
`id` NOT IN (?)
AND `username` LIKE ?
OR `name` LIKE ?
))
ORDER BY `created_at` ASC
LIMIT 11 OFFSET 0
Goal: Search all posts that has body LIKE ?, OR posts that has user; username LIKE ? or name LIKE ? (But also exclude the user we block and the user that block us
Thanks in advance
If there's any unclear explanation, I will edit it A.S.A.P
If I run on my recent laravel install, with my proposed change for one of your issues, version 7.19.1, I get this query:
SELECT
*
FROM
`posts`
WHERE `body` LIKE ?
OR EXISTS <- line of interest
(SELECT
*
FROM
`users`
WHERE `posts`.`user_id` = `users`.`id`
AND (
`id` NOT IN (?)
AND (`username` LIKE ?
OR `name` LIKE ?) <- extra brackets ive added
))
ORDER BY `created_at` ASC
LIMIT 11 OFFSET 0
Have a look at the line of interest, and compare it with the query your version of laravel is running. The AND EXISTS line is being incorrectly generated by laravel. OrWhereHas isnt behaving correctly in your version, I can't find the release number to see where it was fixed.
Id recommend upgrading to latest if possible, but thats not always an option. I've had a dig around, and it looks like the user in this question here encountered a similar problem:
WhereHas() / orWhereHas not constraining the query as expected
You can try moving your $sql->with(['user']); to before you OrWhereHas clause. I'm not sure if that will change it to OR, but its worth a try.
Second thing, I've added whereNested to your OR clause to ensure the precedence is correct, which adds the extra brackets in the query above, as in you dont want:
(`id` NOT IN (1, 2, 3)
AND `name` LIKE % test %)
OR `username` LIKE % test %
Since then it would include your blocked posts in the exists clause.
So final changes look like this, which I think fufills your description:
$sql->with(['user']); //deleted from original position and move here
$sql->where('body', 'LIKE', "%$query%")->whereNotIn('id', $blocks); //additional line
$sql->orWhereHas('ambience', function ($post_user) use ($blocks, $query) {
$post_user
->whereNotIn('id', $blocks);
$post_user->whereNested(function($post_user) use ($query) { //new bit
$post_user->where('name', 'LIKE', "%$query%")
->orWhere('username', 'LIKE', "%$query%");
});
});
I am working on React Native Razorpay payment gateway integration.
I am using react-native-razorpay.
Code is below:-
Send Params are:-
var options = {
description: "Credits towards consultation",
image: "https://i.imgur.com/3g7nmJC.png",
currency: "INR",
key: "a-----b----ccc-dd",
amount: Math.round(Number(order_total).toFixed(2) * 100),
name: "Product",
prefill: {
email: email ? email : "v#razorpay.com",
contact: mobile ? mobile : "1111111111",
name:
firstname && lastname
? `${firstname} ${lastname}`
: "Razorpay Software"
},
theme: { color: theme.colors.primaryColor },
payment_capture: 1
};
Checkout Method:-
RazorpayCheckout.open(options)
.then(data => {
// handle success
console.log("payment success", data);
if (data && data.razorpay_payment_id) {
orderData.payment = data.razorpay_payment_id;
this.props.payMyOrder(orderData);
}
})
.catch(error => {
// handle failure
this.toast.show(error.description);
});
I am getting only razorpay_payment_id in response but, razorpay_payment_id and razorpay_signature are missing. Also, in Razorpay backend Razorpay Order Id and Order Id are missing.
hey as we can see in the above code options object that you are passing to the checkout you are not passing the order_id, you should pass the order_id as well. Since you are not passing the order_id the same is not getting returned to you after the payment is done. refer to the below link on how to create an order at your server-side.
https://razorpay.com/docs/api/orders/
if you pass the order_id in the request param to the checkout you'll get the order_id and signature as well in the payment response.
Please check the documentation we need to pass the order_id, here.
As per the documentation, once you pass the order_id, then only after payment successful razorpay returns the
razorpay_order_id,razorpay_payment_id and razorpay_signature.
After that you can compare the signature to get acknowledgement of payment success.
Just a note if your id is wrong your razorpaySignature too will not appear
Issue mostly will be because of invalid order Id, the order id received from Backend should be the one backend got from Razorpay.
Something like below should be used at your backend to generate order id (format of order id will be order_<some id>). You can get language based backend implementation at this link
var instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' })
instance.orders.create({
amount: 50000,
currency: "INR",
receipt: "receipt#1",
notes: {
key1: "value3",
key2: "value2"
}
})
I am using pubnub for chat , and using userid as channel to send messages , however when i want to retrieve conversation between two users , i need to get data from both channels, how can i do that?
I have data on both channels e.g. "userAid" and "userBid" but if i query
this.pubnub.history(
{ channel: ['userAid,'userBid'], reverse: true, count: 15 },
(status, res) => {
});```
it does not return any result , if i query with only one channel it works
The History SDK call is generally meant to fetch history from a single channel. If you need to fetch history from multiple channels, you need to use Batch History methods.
Refer to https://www.pubnub.com/docs/react-native-javascript/api-reference-storage-and-playback#batch-history for more details.
An example call might be as follows, but the link above provides a list of all the parameters that can be set. Please note that the fetchMessages method can be used to fetch history from a single channel as well.
pubnub.fetchMessages(
{
channels: ['ch1', 'ch2', 'ch3'],
start: "15343325214676133",
end: "15343325004275466",
count: 25
},
(status, response) => {
// handle response
}
);
It seems history can only get messages from one channel.
Try this:
pubnub.fetchMessages({
channels: ['ch1', 'ch2', 'ch3'],
start: '15343325214676133',
end: '15343325004275466',
count: 15,
}, (status, response) => {
// handle status, response
});
Pubnub docs on getting the history:

hello every one i am new in big commerce.
Now i am updating single page checkout using checkout sdk. every thing work fine till now i am following git hub implementing instructions . But the the problem is after update customer shipping address need to select the shipping option for shipping. I am using this syntax for doing this
const saddress = {
address1: $('#shippingaddress').val(),
address2: "",
city: $('#shippingcity').val(),
company: "",
country: $('#shippingcountry').val(),
countryCode: "AU",
customFields: [],
email: $('#email').val(),
firstName: $('#shippingfname').val(),
lastName:$('#shippinglname').val(),
phone: $('#shippingphone').val(),
postalCode: $('#shippingzip').val(),
stateOrProvince: $('#shippingProvince').val(),
stateOrProvinceCode: $('#shippingProvince').val(),
};
const updateaddress = await
service.updateShippingAddress(saddress);
After complete this action the function return all shipping address details along with the ID column and shipping options available in this address. but the problem is that function return the options and also the shipping address details but no ID column found in that list. that's why i am sending the billing address ID for select shipping option this is my code
const newState = await service.selectShippingOption(billing_ID, Shippingoption_ID);
after that i am going to direct payment options my code is
const payment = await service.loadPaymentMethods();
let paymentmethod=payment.data.getPaymentMethods();
in this function i am getting all the payment options details then i go for payment my code is
wait service.initializePayment({ methodId: 'testgateway' });
const payment = {
methodId: 'testgateway',
paymentData: {
ccExpiry: { month: 10, year: 20 },
ccName: 'BigCommerce',
ccNumber: '4111111111111111',
ccType: 'visa',
ccCvv: 123,
},
};
After complete this function this function return a error
Error: "Your order is missing a shipping method. Please return to the
shopping cart and checkout again."
