当字段输入（'float'，'integer'，'monetary'）时，我试图将运算符“between”添加到odoo12ee中。
我正试图覆盖widget domainleaf中的函数_getoperatorsfromtype，但它不起作用，知道吗？

odoo.define('custom_module.DomainLeaf', function(require) {
    "use strict";
    var DomainLeaf = require("web.DomainSelector");
    var Widget = require("web.Widget");

    var core = require("web.core");
    var _t = core._t;
    var _lt = core._lt;

    var operator_mapping = {
        "=": "=",
        "!=": _lt("is not ="),
        ">": ">",
        "<": "<",
        ">=": ">=",
        "<=": "<=",
        "ilike": _lt("contains"),
        "not ilike": _lt("does not contain"),
        "in": _lt("in"),
        "not in": _lt("not in"),

        "child_of": _lt("child of"),
        "parent_of": _lt("parent of"),
        "like": "like",
        "not like": "not like",
        "=like": "=like",
        "=ilike": "=ilike",
        "between": _lt("is between"),

        // custom
        "set": _lt("is set"),
        "not set": _lt("is not set"),
    };
    console.log("Module Loaded");

    var DomainLeaf = DomainLeaf.include({
        template: 'DomainLeaf',
        _getOperatorsFromType: function(type) {
            var operators = {};

            switch (type) {
                case "boolean":
                    operators = {
                        "=": _t("is"),
                        "!=": _t("is not"),
                    };
                    break;

                case "char":
                case "text":
                case "html":
                    operators = _.pick(operator_mapping, "=", "!=", "ilike", "not ilike", "set", "not set", "in", "not in");
                    break;

                case "many2many":
                case "one2many":
                case "many2one":
                    operators = _.pick(operator_mapping, "=", "!=", "ilike", "not ilike", "set", "not set");
                    break;

                case "integer":
                case "float":
                case "monetary":
                    operators = _.pick(operator_mapping, "=", "!=", ">", "<", ">=", "<=", "ilike", "not ilike", "set", "not set", "between");
                    break;

                case "selection":
                    operators = _.pick(operator_mapping, "=", "!=", "set", "not set");
                    break;

                case "date":
                case "datetime":
                    operators = _.pick(operator_mapping, "=", "!=", ">", "<", ">=", "<=", "set", "not set");
                    break;

                default:
                    operators = _.extend({}, operator_mapping);
                    break;
            }

            if (this.options.operators) {
                operators = _.pick.apply(_, [operators].concat(this.options.operators));
            }

            return operators;
        },

    });
});

我没有收到任何错误，除了继承函数的行为没有改变外，其他一切都正常。我已将.js文件添加到assets_后端，模块已正确加载，但函数未被覆盖。
