Set "Replacement Reason" when replacing part of one to one relationship

[onepoint0]

Hi Devs,

I am working on espo version 8.2.2.

I have a one to one relationship set up between a Device and Camera. When I replace the camera on the device I want to make the user set a reason for replacement which I'll then save into a device history table that I have created in the backend. I have a custom saver (eg FieldProcessing with a SaverInterface) set up that creates the device history records.

To make the user enter the replacement reason I have extended the views/modals/select-records view and instead of just closing it on select, I am opening a second modal which asks for a replacement reason (this is called in the select listener in setupList):

define('custom:default-filter/select-mmx-camera', ['views/modals/select-records'], function (Dep) {

  return Dep.extend({

    className: 'dialog dialog-record',

    backdrop: true, // 'static', true, false

    data: function () {
      var data = Dep.prototype.data.call(this);
      console.log('custom cam select data ',data);
      return data;
    },

    setup: function () {
      Dep.prototype.setup.call(this);
      // par = this.getParentView().model;
      console.log(`my camera select.js this = `,this);
    },

    setupList() {

      const viewName = this.getMetadata().get('clientDefs.' + this.scope + '.recordViews.listSelect') ||
        this.getMetadata().get('clientDefs.' + this.scope + '.recordViews.list') ||
        'views/record/list';

      const promise = this.createView('list', viewName, {
        collection: this.collection,
        fullSelector: this.containerSelector + ' .list-container',
        selectable: true,
        checkboxes: this.multiple,
        massActionsDisabled: true,
        rowActionsView: false,
        layoutName: this.layoutName,
        searchManager: this.searchManager,
        checkAllResultDisabled: !this.massRelateEnabled,
        buttonsDisabled: true,
        skipBuildRows: true,
        pagination: this.getMetadata().get(['clientDefs', this.scope, 'listPagination']) || null,
      }, view => {

        this.listenToOnce(view, 'select', model => {
          if ( model.get(`isInUse`) == 1 ) {  
            Espo.Ui.error( `${model.get('name')} is attached to another Device. Please select another camera.`, true);
        } else {
          console.log(`in open reason modal`);
          this.reasonModal(model);
        }
          // this.trigger('select', model);
          //   this.close();
        });

        const fetch = () => {
            this.whenRendered().then(() => {
                Espo.Ui.notify(' ... ');
                this.collection.fetch()
                    .then(() => Espo.Ui.notify(false));
            });
        };

        view.getSelectAttributeList(selectAttributeList => {
          if (!~selectAttributeList.indexOf('name')) {
              selectAttributeList.push('name');
          }
          const mandatorySelectAttributeList = this.options.mandatorySelectAttributeList ||
              this.mandatorySelectAttributeList || [];
          mandatorySelectAttributeList.forEach(attribute => {
              if (!~selectAttributeList.indexOf(attribute)) {
                  selectAttributeList.push(attribute);
              }
          });
          if (selectAttributeList) {
              this.collection.data.select = selectAttributeList.join(',');
          }
          fetch();
        });
      });
      this.wait(promise);
    },

    reasonModal: function (model) {
      this.createView('reasonModal', 'custom:service-replace-part-reason-dialog', {
        title: 'Add reason',
      }, view => {
        view.render();
        view.listenToOnce(view, 'done', response => {
          console.log(`get parent view `,this.getParentView());
          this.getParentView().model.set('replacementReason',response.replacementReason);
//            model.set('replacementReason',response.replacementReason);
            console.log(`reason response = `,model);

            this.trigger('select', model);
            this.close();
         })
      });
    }
  });
});​

The second modal works and gets the reason.

But I have two problems - one is that I can't figure out how to pass the reason back to the parent view - I have done it here in the reasonModal function using

          this.getParentView().model.set('replacementReason',response.replacementReason);

I can see the value in the parent view on the device model but it feels like a bad hack as it doesn't belong there.

The second is that even when I do that, the replacement reason is not on the entity when it gets to the saver in the back end. I suspect this is because it's not a real field on the entity as defined in entityDefs, but I can't find any way to pass extra data to the saver.

Does anyone know how I can pass the reason back to the parent view from the modal and then make it accessible in the saver in the back end?

Cheers,
