Hi, I have a model which contains a parent and several children.

The parent has a computed field "product_remaining", which is updated from the modification of a different field in any of the children ("lot_qty").

The field "product_remaining" is shown in a tree for all children, using a "related" field in the children's model.

Everything is working fine, except that the tree only updates the "product_remaining" field in the row for which the modification has been done, and it does not update any other line.

Furthermore, if I click to modify a line which has not been updated by a previous change, and leave without modify it, the line gets updated correctly.

Is any way to update/refresh all the affected lines in the tree view, and not only the one where the change has been made?

I am using Odoo v10.

Here is the relevant code:

Python:

class Te2PackLotOperation(models.TransientModel):
    _name = 'te2.pack.lot.operation'
    parent_id = fields.Many2one('te2.pack.product.operation', readonly=True, ondelete='cascade')
    product_id = fields.Many2one('product.product', 'Product', related='parent_id.product_id')
    product_qty = fields.Float('Total', readonly=True, related='parent_id.product_qty')
    product_remaining = fields.Float('Remaining', readonly=True, related='parent_id.product_remaining')
    lot_id = fields.Many2one('stock.production.lot')
    lot_qty = fields.Float('Done')
    packing = fields.Char('Packing')
    @api.onchange('lot_qty')
    def onchange_lot_qty(self):
        rec = self._origin
        rec.write({'lot_qty': self.lot_qty})

class Te2PackProductOperation(models.TransientModel):
    _name = 'te2.pack.product.operation'
    product_id = fields.Many2one('product.product', 'Product', readonly=True)
    product_qty = fields.Float('Total', readonly=True)
    product_remaining = fields.Float('Remaining', readonly=True, compute='_product_remaining_get')
    lot_ids = fields.One2many('te2.pack.lot.operation', 'parent_id')
    @api.one
    @api.depends('lot_ids', 'lot_ids.lot_qty')
    def _product_remaining_get(self):
        already_done = 0
        for lot in self.lot_ids:
            already_done += lot.lot_qty
        self.product_remaining = self.product_qty - already_done

XML:

        <record id="te2_stock_picking_advanced_view_form" model="ir.ui.view">
            <field name="name">te2.pack.operation.form</field>
            <field name="model">te2.pack.product.operation</field>
            <field name="arch" type="xml">
                <form string="Advanced Stock Picking">
                    <field name="lot_ids">
                        <tree editable="bottom" create="false" delete="false"
                              decoration-danger="product_remaining!=0" decoration-success="product_remaining==0"
                              default_order="product_id">
                            <field name="product_id"/>
                            <field name="product_qty"/>
                            <field name="product_remaining"/>
                            <field name="lot_id"
                                   domain="[('product_id','=', product_id)]"
                            />
                            <field name="use_date"/>
                            <field name="lot_qty"/>
                            <field name="packing"/>
                            <button name="add_lot" string="Lot Split" type="object" icon="fa-list"/>
                        </tree>
                    </field>
                    <footer>
                        <button name="save" string="Save" type="object" class="oe_highlight" />
                        <button string="Cancel" class="oe_link" special="cancel"/>
                    </footer>
                </form>
            </field>
        </record>

Ok, after some digging, I have managed to solve the issue by extending the JavaScript classes.

If somebody is interested, the code is as follows:

odoo.define('te2_base', function(require) {
  "use strict";

  var core = require('web.core');

  //The ListView. This view is used by the one2many field (see below)
  var One2ManyUpdateAllListView = core.one2many_view_registry.get('list').extend({
    init: function(viewmanager) {
      var result = this._super.apply(this, arguments);
      //Register to the save event
      this.on("save:after", this, this.reload_all_records);
      return result;
    },

    //Similar to "reload_record" from "list_view.js", but supporting an array of records, and moving the
    //100ms delay to the end of the operation, instead of one delay per record.
    reload_records: function (records, options={}) {
        var self = this;
        var fields = this.fields_view.fields;

        if (!options || !options.do_not_evict) {
            //This is from "form_relational_widgets.js".
            // Evict records from cache to ensure it will be reloaded correctly
            records.each( function (record) {
                self.dataset.evict_record(record.get('id'));
            })
        }

        return this.dataset.read_ids(
            records.map(function (record) {return record.get('id')}),
            _.pluck(_(this.columns).filter(function (r) {
                    return r.tag === 'field';
                }), 'name'),
            {check_access_rule: true}
        ).then(function (upd_records) {
          records.each(function (record) {
            var values = upd_records.find(function (upd_r) {return upd_r['id'] == record.get('id')});
            if (values == undefined) {
              self.records.remove(record);
            } else {
              // _.each is broken if a field "length" is present
              for (var key in values) {
                  if (fields[key] && fields[key].type === 'many2many')
                      record.set(key + '__display', false, {silent: true});
                  record.set(key, values[key], {silent: true});
              }
              record.trigger('change', record);
            }
          });

          var def = $.Deferred();
          setTimeout(function() {
              def.resolve();
          }, 100);
          return def;
        });
    },
    reload_all_records: function () {
      return this.reload_records(this.records);
    },
  });

  //The Field. We should override the listview used by the field, so it uses our custom view.
  var FieldOne2ManyUpdateAll = core.form_widget_registry.get('one2many').extend({
    init: function() {
      var result = this._super.apply(this, arguments);
      this.x2many_views.list=One2ManyUpdateAllListView;
      return result;
    }
  });

  //Register the new field, so we can use it from our XML files
  core.form_widget_registry.add('te2_tree_update_all', FieldOne2ManyUpdateAll);

  //Make the classes available for other modules.
  return {
    One2ManyUpdateAllListView: One2ManyUpdateAllListView,
    FieldOne2ManyUpdateAll: FieldOne2ManyUpdateAll
  };
});

And it can be used just by adding the widget attribute to the field tag (note: it should be added to the "field" tag, not to the "tree" tag):

<field name="lot_op_ids" options='{"always_reload": True}' widget="te2_tree_update_all">

Best regards,

Ruben
