Apex SDK for Slack Beta

Hi

I am facing an issue in creating YAML file in my VS Code. The requirement is to fetch Page Layout of a custom object in apex and use the field API names and Lables in YAML file (the one we create in .view file in viewdefinitions folder) to create a Record Create Form. 

I wrote the following code to return a List of key value pairs in apex.

    public static List<FieldData>  getHelpdeskLayout() {

        List<FieldData> fieldsList = new List<FieldData>();

        List<Metadata.Metadata> layouts = Metadata.Operations.retrieve(Metadata.MetadataType.Layout, new List<String> {'Helpdesk__c-Helpdesk Ticket Layout'});

        Metadata.Layout layoutMd = (Metadata.Layout)layouts.get(0);

        for (Metadata.LayoutSection section : layoutMd.layoutSections) {

            for (Metadata.LayoutColumn column : section.layoutColumns) {

                if (column.layoutItems != null) {

                    for (Metadata.LayoutItem item : column.layoutItems) {

                        System.debug(item);

                        Map<String, Schema.SObjectField> mfields = Schema.Helpdesk__c.SObjectType.getDescribe().fields.getMap();

                        Schema.DescribeFieldResult fieldResult = mfields.get(item.field).getDescribe();

                        System.debug('fieldResult.getLabel()  ' +fieldResult.getLabel());

                        System.debug('item.field  ' +item.field);

                        FieldData fieldData;

                        if(item.field =='Name')

                        {

                            fieldData = new FieldData(fieldResult.getLabel(), item.field,true,'textInput');

                        }

                        else{

                            fieldData = new FieldData(fieldResult.getLabel(), item.field,false,'textInput');

                        }

                        fieldsList.add(fieldData);                      

                    }

                }

            }

        }

        System.debug('fieldsList  ' +fieldsList);

        return fieldsList;    

    }

Note: FieldData is a wrapper class

global class FieldData {

    global String label;

    global Object value;

    global boolean isRequired;

    global String fieldType1;

    global FieldData(String label, Object value,boolean isRequired,String fieldType1) {

        this.label = label;

        this.value = value;

        this.isRequired = isRequired;

        this.fieldType1 = fieldType1;

    }

}

Following is the YAML file that I created 

description: "This component displays record details in a message"

schema:

  properties:

    headerText:

      type: string

      defaultValue: "Record Details"

dataproviders:

  record:

    definition: "apex__DataProviderSObjectRecord.getHelpdeskLayout"

components:

  - definition: modal

    properties:

      title: "Create Helpdesk Ticket"

      submitLabel: "Create"

    events:

      onsubmit:

        # definition maps to 'ActionDispatcherSubmitRecord' apex class implementing Slack.ActionDispatcher

        definition: "apex__action__ActionDispatcherSubmitRecord"

        properties:

          objectApiName: "Helpdesk__c"

    components:

      - definition: divider

      - definition: iteration

        properties:

          foreach: "{!record}"

          foritem: "record"

        components:

          - definition: input

            properties:

              label: "{!record.label}:"  # label is the field label

              required: "{!record.isRequired}"

            components:

              - definition: "{!record.fieldType1}"

                properties:

                  name: "{!record.value}"   # name should be FieldApiName

I get the error in apex saying "No component was found with definition {!record.fieldType1}"

My goal is to dynamically provide definition (textInput, Numer, datepicker, etc) in the iteration. I can't figure out what I am doing wrong here. 

Hi

I have been trying to set up Salesforce for Slack in my developer account connecting to Slack developer sandbox account. Things are fine with connection and I have a custom flow to send a message from Salesforce to slack using “send message” core action. It is posting link to the record but in slack it just appears as a link and does not unfurl into data and button as shown here.

Any suggestion on how to fix this?

CRUD layout and unfurl slack record layouts are working fine. When I post the same link manually as a user in slack, it works but when posted by the app “Salesforce for slack” by the flow it just remains as a link.

Thanks!
