What is the difference between a User and a GuildMember in discord.js?
(2 answers)
Closed 2 years ago.
Im trying to add a command to my bot, said command will display the avatar of whoever is mentioned. For example
>pfp #user1 would display user1's avatar.
However my code is returning an error of message.member.displayAvatarURL(); is not a function
let member = message.mentions.members.first();
if(member){
message.member.displayAvatarURL();
}
What would be the appropriate syntax to execute this?
displayAvatarURL is a function on User, not GuildMember.
You can either get the user from the member like this:
message.member.user.displayAvatarURL();
or just directly use the author property:
message.author.displayAvatarURL();

How can I use optional chaining with arrays and functions?
(6 answers)
Closed 3 months ago.
I fetched data from an API and I get this :
An array of arrays containing objects and properties containing the details of songs.
The issue is when i try to access the uri property, I get "Cannot read properties of undefined (reading '1')" with the code below :
const songTitleEl = chartData.map(data =>(
<ChartSongs key={data.key} audio={data?.hub?.actions[1]?.uri}/>
))
It should be working perfectly but it isn't and for the life of me I can't figure why.
actions could be null. Need the ? to check if index exists
<ChartSongs key={data.key} audio={data?.hub?.actions?.[1]?.uri}/>

How to add items to a spinner in Android?
(11 answers)
Closed 2 years ago.
I have a spinner where the contents are from an Array in Strings.xml. However I would like to be able to let the user add items to the array. Can anyone help and let me know if there is a way to do this?
Many thanks
ArrayAdapter has a method add(object) as seen here: ArrayAdapter | Android Developer
For example:
fun addItem(item: T) {
arrayAdapter.add(item)
// Refreshes the view to reflect the changes applied to arrayAdapter
arrayAdapter.notifyDataSetChanged()
}

Nodejs: url.parse issue with arrays inside query
(2 answers)
Closed 6 years ago.
I'm working in a MEAN app, in which I want to pass an array value to url and fetch values from mongodb. Actually it's a lat and lng. My url should look like:
http://localhost:8080/search?type=latlng&value=[0.123, 0.456]
And have to fetch data related to that lat lng. How to do that?
You cannot pass literal array objects in the URL like you propose. There are workarounds however. You must either separate the data into {key}={value} pairs within the URL, or use a POST request.
GET: http://localhost:8080/search?type=latlng&lat=0.123&lng=0.456
http://localhost:8080/search?type=latlng&coords[]=0.123&coords[]=0.456
POST: http://localhost:8080/search
data: { type: 'latlng', value: [0.123, 0.456] }

Determine whether an array contains a value [duplicate]
(18 answers)
Closed 7 years ago.
I have array of name:
$scope.myArray with some values.
Now I want to check an Item is present in array or not,
If it is not present then I want to push that item into array and If that item is already in array then I don't want to push it.
Please tell me how to do this ?
if($scope.myArray.indexOf(item) === -1) {
$scope.myArray.push(item)
}
You can read about indexOf for more details. Also, checkout underscore js for some readily available functions.

AuthComponent: Difference between allowedActions and allow()?
What is the difference between using the method
$this->Auth->allow()
and setting the variable
$this->Auth->allowedActions ?
I can't find any information about setting the allowedActions array where I expected to find it (http://book.cakephp.org/view/1251/Setting-Auth-Component-Variables) - but it exists in the API at http://api13.cakephp.org/class/auth-component.
Can someone please explain which different circumstances I should use them?
