I am using a 'Custom Datatable' solution in order to modify picklist values within a datatable. Project code may be referenced here:
https://live.playg.app/play/picklist-in-lightning-datatable
I have made changes so that I can retrieve data from the custom object: Payment__c, and I am attempting modify the picklist values for the Payment_Status__c field. My 'debugging' method has been to create numerous console.log statements to verify data during the updating process. Picklist values are currently hardcoded (have not figured out how to dynamically pull from SF yet). Inline edit of individual cells works fine, and I am able to save those values as well (though changes are not reflected until I perform a manual page refresh). Picklist selection is working, but I am unable to save the currently selected picklist value in the datatable.
I believe that the intended trigger event for picklist selection changes--'valueselect', is not being fired, and the handleSelection method is not receiving this event when a new picklist selection is made.

As this is my first time working with Lightning Web components, I would greatly appreciate any assistance you may provide. Thanks in advance.
I was able to get this custom data table component working for something I am developing to effectively bind records as rows. Here 2 differences I notice:
I did not include onvalueselect and oncellchange methods for the component html declaration, only the onpicklistchanged.
You may want to use your custom server side controller method instead of the built-in uiRecordApi->updateRecord one. Something tells me this may not play nice with row data from the data table. In my implementation, I was simply able to pass the draftValues over to the server side method which has a single parameter of list of sObject:
async saveRecords(event){
const updatedFields = event.detail.draftValues;
this.draftValues = [];
this.showSpinner = true
try{
await saveRelatedRecords({sObjs: updatedFields}) // server side save
.then((result) => {
this.updateMessage = result;
})
this.showSpinner = false;
if(this.updateMessage == 'success'){
this.showToast('Success', 'Record(s) Updated', 'success');
} else{
this.showToast('Error', this.updateMessage, 'error');
}
await refreshApex(this._wiredRecordData);
this.unsavedData = this.records;
} catch (error) {
this.showSpinner = false;
this.showToast('Error while updating or refreshing records', error.body.message, 'error');
}
}
In regards to your data not refreshing, I suggest you wire your getPayments method so that you can always get a fresh set from the server side, rather than trying to keep track of and maintain data changes on the client side, something like:
_wiredRecordData;
#wire(getRelatedRecords)
relatedRecords(getRecsResult){
const { data, error } = getRecsResult;
this._wiredRecordData = getRecsResult;
if(data){
this.records = data;
}
}
Then after your success toast in your save method, you can use
await refreshApex(_wiredRecords); and lwc knows to rerender based on the wiring (or at least I think that's how it works.)
Lastly, here is the server side controller method I have to dynamically generate column header information so it does not need to be hard coded into the component. However I did need to modify the custom component a bit to include a new "fieldapi" attribute so that the client side method knows what field to set for the changed value during the onpicklistchanged action.
#AuraEnabled(cacheable=true)
public static String getColumnHeaders(String sObjAPI, String fieldAPIs)
{
List<ColumnHeaderInfo> colHeaders = new List<ColumnHeaderInfo>();
Schema.DescribeSObjectResult sObjDesc = Schema.getGlobalDescribe().get(sObjAPI).getDescribe();
Boolean objIsUpdateable = sObjDesc.isUpdateable();
Map<String, Schema.SObjectField> objFields = sObjDesc.fields.getMap();
for(String field: fieldAPIs.split(','))
{
if(!objFields.keySet().contains(field.toLowerCase())){
continue;
}
Schema.DescribeFieldResult fieldDesc = objFields.get(field).getDescribe();
if(!fieldDesc.isAccessible()){
continue;
}
ColumnHeaderInfo colHeader = new ColumnHeaderInfo();
colHeader.label = fieldDesc.getLabel();
colHeader.fieldName = fieldDesc.getName();
colHeader.editable = fieldDesc.isUpdateable() && sObjDesc.isUpdateable();
colHeader.type_x = fieldDesc.getType().name().toLowerCase();
if(colHeader.type_x == 'picklist')
{
colHeader.type_x = 'picklist';
List<Schema.PicklistEntry> picklistValues = fieldDesc.getPicklistValues();
colHeader.typeAttributes = new TypeAttributes();
colHeader.typeAttributes.options = new List<Option>();
for(Schema.PicklistEntry ple: picklistValues)
{
Option opt = new Option();
opt.value = ple.getValue();
opt.label = ple.getLabel();
colHeader.typeAttributes.options.add(opt);
}
colHeader.typeAttributes.context = new FieldName();
colHeader.typeAttributes.context.fieldName = 'Id';
colHeader.typeAttributes.value = new FieldName();
colHeader.typeAttributes.value.fieldName = fieldDesc.getName();
colHeader.typeAttributes.fieldapi = fieldDesc.getName();
}
// multi-select picklist fields not supported so make them read-only
if(colHeader.type_x == 'multipicklist'){
colHeader.editable = false;
}
colHeaders.add(colHeader);
}
return JSON.serialize(colHeaders).replaceAll('type_x', 'type');

I have a vue application where I am displaying information inside of vuetify chips. When I want to click on a specific chip I want the console to log the value inside it. I tried accessing the array which the information originate from but I am getting an undefined error. Could someone look at my code and tell me what is wrong with it?
html:
<v-chip-group
v-model="selection"
active-class="deep-purple--text text--accent-4"
mandatory
>
<v-chip
v-for="(time, i) in dateTimeArray"
:key="time"
:value="time.startTime+' | '+time.endTime"
#click="pushSelected()"
>
{{ time.startTime +" : "+ time.endTime }}
</v-chip>
</v-chip-group>
Script:
export default {
name: "MeetingAdminComponent",
data : ()=>({
singleSelect: false,
selection: "",
dateTimeArray:[],
availableTimes: [
],
}),
created() {
this.getAvailableMeetingTimes()
},
methods:{
getAvailableMeetingTimes() {
var pageURL = window.location.href;
var lastURLSegment = pageURL.substr(pageURL.lastIndexOf('/') + 1);
axios.get("http://localhost:8080/api/voterAvailableTime/findBy", {
params: {
meetingName: lastURLSegment,
}
})
.then(response => (this.availableTimes = response.data)
)
},
getTimesFilteredByDate() {
var pageURL = window.location.href;
var lastURLSegment = pageURL.substr(pageURL.lastIndexOf('/') + 1);
var selectedDate = this.selectedDate
axios.get("http://localhost:8080/api/voterAvailableTime/find", {
params: {
meetingName: lastURLSegment,
date: selectedDate
}
})
.then(response => (this.dateTimeArray = response.data))
},
pushSelected(){
console.log(this.availableTimes.startTime+ " " + this.availableTimes.endTime)
}
}
};
</script>
Pass the current item as parameter to the method :
<v-chip
v-for="(time, i) in dateTimeArray"
:key="time"
:value="time.startTime+' | '+time.endTime"
#click="pushSelected(item)"
in methods:
pushSelected(item){
console.log(item.startTime+ " " + item.endTime)
}
While I am trying to add this JSON data into Database then it is giving me the above Error!
var tax_setting = '{ "total_tax_settings": { "charge_tax": ' + this.taxInfoRadioButton +
', "tax_settings" : [' +
'{ "tax_name": ' + this.taxName +
', "tax_rate": ' + this.taxRate +
', "tax_included_in_price": ' + this.taxIncludeInPrice + ' } ]}}';
Radio Button of this JSON:
<v-radio-group v-model="taxInfoRadioButton">
<v-radio color="primary" label="Do not charge tax on purchases" value="1"></v-radio>
<v-radio color="primary" label="Charge tax on purchase" value="2"></v-radio>
</v-radio-group>
data() {
return {
taxInfoRadioButton: '1'
}
}
Text Field:
<v-text-field name="taxName" label="Tax Name" id="taxName" v-model="taxName"></v-text-field>
data() {
return {
taxName: ''
}
}
Tax Rate is also same as above.
Select Option in JSON:
<v-select hide-details v-bind:items="willTaxInclude" v-model="taxIncludeInPrice" label="Select" single-line menu-props="bottom" ></v-select>
data() {
return {
willTaxInclude: [
{ text: "Yes", value: 1 },
{ text: "No", value: 0 }
],
taxIncludeInPrice: '0',
}
}
Parse it in JSON format:
var tax_setting = JSON.parse(tax_setting);
I am passing this data to Database using axios
axios.post('/api/data/user/save-business-settings', {
tax_setting: tax_setting,
}).then((res) => {
console.log(res);
}).catch((err) => {
console.log(err);
})
What is the problem I can't figure out Actually. Please help me.
The number #1 rule to keep in mind when working with JSON is...
NEVER ROLL YOUR OWN JSON
JSON is best created by first creating the object you want to serialise, then passing that to JSON.stringify(). Since you're using Axios, you don't even have to do that since Axios does it for you; you simply pass it the object you want POSTed.
const tax_setting = {
total_tax_settings: {
charge_tax: this.taxInfoRadioButton,
tax_settings: [{
tax_name: this.taxName,
tax_rate: this.taxRate,
tax_included_in_price: this.taxIncludeInPrice
}]
}
}
axios.post('/api/data/user/save-business-settings', { tax_setting })
.then(...)
I am using Bootstrap Vue and would like to add a column dynamically or only show the column if some condition is met in the data. I'm trying to understand scoped slots and whether this is the direction I should take with a formatter callback function. Ideally I would like to add a column "Version 2" only if it is available in the data. I'm not sure where to start.

I think this is something, you are looking for:
<b-table :items="items" :fields="fields">
<template v-for="field in dynamicFields" v-slot:[`cell(${field.key})`]="{ item }">
</b-table>
in scripts:
this.dynamicFields.push({key: 'someTestKey', label: 'Dynamic Label'})
My component vue.js is like this :
<script>
export default{
name: 'CategoryBsSelect',
template: '\
<select class="form-control" v-model="selected" required>\
<option v-for="option in options" v-bind:value="option.id" v-bind:disabled="option.disabled">{{ option.name }}</option>\
</select>',
//props: {list: {type: String, default: ''}},
mounted() {
this.fetchList();
},
data() {
return {
selected: '',
options: [{id: '', name: 'Pilih Kategori'}]
};
},
methods: {
fetchList: function() {
this.$http.post(window.BaseUrl+'/member/category/list').then(function (response) {
//this.$set('list', response.data);
console.log(JSON.stringify(response.body))
Object.keys(response.body).forEach(function (key) {
console.log(key)
console.log(response.body[key])
this.$set(this.options, key, response.body[key]);
}, this);
});
},
}
};
</script>
The result of console.log(JSON.stringify(response.body)) :
{"20":"Category 1","21":"Category 2","22":"Category 3"}
I want display the response on the value of select. But when executed, on the console exist error like this :
TypeError: Cannot read property 'id' of undefined
Is there anyone who can help me?
The issue you are having is the final this.options variable is an hash nat an array, which should be an input to select element, you can modify you code inside fetchList method like following:
Object.keys(resp).forEach((key) => {
console.log(key)
console.log(resp[key])
this.options.push({
id: key,
name: resp[key]
})
});
