GM - RelatedList Grid

(gmpkg:RelatedListDataGridComponent)

Documentation

GM - RelatedList Grid component is used to display a specified related list based on the assigned layout to the current user. This component requires the permission API Enabled.

Use case: Display a grid of opportunities on the account page.

Specification

The following properties use JSON syntax as part of their configuration: Filter, Aggregate, Default Values, Actions, Related Record Grids, Custom Field Labels, Cell Coloring.

The configuration wizard can be run to generate the required JSON strings for each of these properties. More details on the JSON syntax is available at the following location: w3schools.com - JSON syntax.

Property	Type	Description
recordId	String	recordId to use. Keep this empty if you want to use the current record.
Related List Label *	String	The label defined on the layout page. Set it to Contacts to display the list of contacts on the Account page.
Row Limit *	Integer	The maximum number of rows to fetch. The grid will never go beyond this number of records. The default value is 100.
Page Size *	Integer	The number of rows to fetch per step. If you have a contact related list of 50. If you set the Row Limit to 20 and the Page Size to 10. The first load of the grid will show 10 records and the grid title will be ‘Contacts (10+)’. The ‘+’ sign indicates that there are more records to load. You can fetch more rows using the ‘Load More’ button. The default value is 10.
Enable Pagination	Boolean	Check this option to enable pagination instead of scrolling. Note: this option is not compatible with interactive filters.
Custom Label	String	Override the title of the data grid. This is relevant when the related list is filtered. We can combine the filtering and the custom title to display different grids. You can filter only closed opportunities and set the title to Closed Opportunities.
Custom Icon	String	Customize the data grid icon. All lightning icons are supported. You can get the icon name from https://lightningdesignsystem.com/icons/
Grid Height	Integer	Set the grid height. Set this property if you want to control the height and show up components after the grid. The user has to scroll vertically to see more records. If the value is set 9999, The grid will use the remaining space on the page even if the user resizes the window. This behavior is relevant to build a responsive app page.
Formula Columns	String	JSON string to define formula columns. A formula column is not saved in the database. it's calculated on the fly when the grid is rendered or when the record is edited by the user. The configuration wizard can be used to set this property (See Dynamic Formula guide). The produced configuration can be be adjusted to set the column index of each formula. See the example below: { "name": "ARR9qfzn__f", "fieldApiName": "ARR9qfzn__f", "label": "ARR", "type": "Currency", "JSFormula": "Amount*12", "isClientSide": true, "isJSFormula": true, "digits": "0", "precision": "18", "scale": "2", "index": 2 }

Extra Cell Coloring	String	Extra JSON conditions for cells coloring. This property is useful for complex coloring that go beyond 2000 characters.
Lookup Fields Options	String	JSON string to customize lookup fields. You can define different aspects for each lookup field. Title field : Field ApiName for the title Subtitle field : Field ApiName for subtitle Candidates provider : In some situations, the search is very complex especially for lookup filters.

density	String	Grid density : comfy | compact. Currently the density is applied only to the toolbar. The compact layout is more for inline Grids.

Lightning App Builder support custom labels to dynamically configure any component property. This feature is useful when dealing record types or any property depending on the environment. Below is an example of default values using custom labels:

{
    "RecordTypeId": "{!$Label.Outbound_Contact}"
}

The candidate's provider class should implement a Callable interface. GridMate delegates the candidates search to the given provider:

Callable handler =  (Callable) Type.forName(candidatesProvider).newInstance();
            return (Object[]) handler.call('getLookupCandidates', new Map<String, Object>{
                                              'objectId' => objectId,
                                              'refObjName' => refObjName,
                                              'refFieldName'=> refFieldName,
                                              'searchTerm'=> searchTerm,
                                              'titleField'=> titleField,
                                              'subTitleField'=> subTitleField});

The example below showcase a specific provider for ‘AccountId’ on Case object:

The apex class should be declared as global. If not we will not be able to instantiate the class from the managed package.

global class CaseAccountCandidatesProvider implements Callable {
    global Object call(String action, Map<String, Object> args) {
        if(action=='getLookupCandidates'){
            String query = 'Select Id, Name From Account';            
            String searchTerm = (String)args.get('searchTerm');
            if(searchTerm != null){query += ' Where Name like \'' +  searchTerm + '%\'';}
            query += ' Limit 5';           
            List<Object> items = Database.query(query);                            
            if(items != null && items.size()>0){
                String jsonItems = JSON.serialize(items);
                return (List<Object>)JSON.deserializeUntyped(jsonItems);
            }
            return null;
       }else {throw new ExtensionMalformedCallException('Action not implemented');}
    }
}

Grid Wrapping

GM - RelatedList Grid is an Aura Component and therefore can be wrapped in another component through composition. Below is an example of what could be done:

ContactsGridComponent.cmp

<aura:component
    implements="flexipage:availableForAllPageTypes,force:hasSObjectName,force:hasRecordId"
    access="global"
>
    <gmpkg:RelatedListDataGridComponent
        aura:id="relatedGrid"
        recordId="{! v.recordId }"
        sObjectName="Account"
        relatedListLabel="Contacts"
        onCellChange="{! c.handleCellChange }"
    />
</aura:component>

ContactsGridComponentController.js

({
    handleCellChange: function (component, event, helper) {
        let dataGrid = component.find('relatedGrid');

        let item = event.getParam('item');
        let column = event.getParam('column');
        let value = event.getParam('value');

        if (column.fieldApiName === 'Approval_Status__c') {
            if (value === 'Accepted') {                
                dataGrid.setCellDisplayMode(item.UID, 'Title', 'read');                
            } else {
                dataGrid.setCellDisplayMode(item.UID, 'Title', 'edit');                
            }
        }       
    }
});
