Question

我试图将数组的一个元素设置为不同的对象。但是，编译器正在删除MyCollection运算符。为什么这样做呢？我该如何解决它？

示例代码：

编译此代码段时我遇到的编译器错误是：

struct IntContainer
{

    IntContainer(const int value) :
    value(value)
    {
    }

    IntContainer() :
    IntContainer(0)
    {
    }

    const int value;
};

int main(int argc, char** argv)
{

    IntContainer intContainers[3];
    IntContainer newIntContainer(420);
    intContainers[0] = newIntContainer; // <-- Causes compiler error

    return 0;
}

编译器通常会免费为您提供<field name="inherit_id" ref="product.product_template_form_view_invoice_policy" />和复制构造函数，但是当一个类包含2017-10-03 13:19:11,524 21646 ERROR miningsearchesuk werkzeug: Error on request: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/werkzeug/serving.py", line 180, in run_wsgi execute(self.server.app) File "/usr/lib/python2.7/dist-packages/werkzeug/serving.py", line 168, in execute application_iter = app(environ, start_response) File "/usr/lib/python2.7/dist-packages/odoo/service/server.py", line 249, in app return self.app(e, s) File "/usr/lib/python2.7/dist-packages/odoo/service/wsgi_server.py", line 184, in application return application_unproxied(environ, start_response) File "/usr/lib/python2.7/dist-packages/odoo/service/wsgi_server.py", line 170, in application_unproxied result = handler(environ, start_response) File "/usr/lib/python2.7/dist-packages/odoo/http.py", line 1308, in __call__ return self.dispatch(environ, start_response) File "/usr/lib/python2.7/dist-packages/odoo/http.py", line 1282, in __call__ return self.app(environ, start_wrapped) File "/usr/lib/python2.7/dist-packages/werkzeug/wsgi.py", line 591, in __call__ return self.app(environ, start_response) File "/usr/lib/python2.7/dist-packages/odoo/http.py", line 1463, in dispatch odoo.registry(db).check_signaling() File "/usr/lib/python2.7/dist-packages/odoo/__init__.py", line 52, in registry return modules.registry.Registry(database_name) File "/usr/lib/python2.7/dist-packages/odoo/modules/registry.py", line 59, in __new__ return cls.new(db_name) File "/usr/lib/python2.7/dist-packages/odoo/modules/registry.py", line 82, in new odoo.modules.load_modules(registry._db, force_demo, status, update_module) File "/usr/lib/python2.7/dist-packages/odoo/modules/loading.py", line 335, in load_modules force, status, report, loaded_modules, update_module) File "/usr/lib/python2.7/dist-packages/odoo/modules/loading.py", line 237, in load_marked_modules loaded, processed = load_module_graph(cr, graph, progressdict, report=report, skip_modules=loaded_modules, perform_checks=perform_checks) File "/usr/lib/python2.7/dist-packages/odoo/modules/loading.py", line 156, in load_module_graph _load_data(cr, module_name, idref, mode, kind='data') File "/usr/lib/python2.7/dist-packages/odoo/modules/loading.py", line 95, in _load_data tools.convert_file(cr, module_name, filename, idref, mode, noupdate, kind, report) File "/usr/lib/python2.7/dist-packages/odoo/tools/convert.py", line 845, in convert_file convert_xml_import(cr, module, fp, idref, mode, noupdate, report) File "/usr/lib/python2.7/dist-packages/odoo/tools/convert.py", line 915, in convert_xml_import obj.parse(doc.getroot(), mode=mode) File "/usr/lib/python2.7/dist-packages/odoo/tools/convert.py", line 796, in parse self.parse(rec, mode) File "/usr/lib/python2.7/dist-packages/odoo/tools/convert.py", line 799, in parse self._tags[rec.tag](rec, de, mode=mode) File "/usr/lib/python2.7/dist-packages/odoo/tools/convert.py", line 695, in _tag_record f_val = self.id_get(f_ref) File "/usr/lib/python2.7/dist-packages/odoo/tools/convert.py", line 782, in id_get res = self.model_id_get(id_str, raise_if_not_found) File "/usr/lib/python2.7/dist-packages/odoo/tools/convert.py", line 788, in model_id_get return self.env['ir.model.data'].xmlid_to_res_model_res_id(id_str, raise_if_not_found=raise_if_not_found) File "/usr/lib/python2.7/dist-packages/odoo/addons/base/ir/ir_model.py", line 1075, in xmlid_to_res_model_res_id return self.xmlid_lookup(xmlid)[1:3] File "<decorator-gen-5>", line 2, in xmlid_lookup File "/usr/lib/python2.7/dist-packages/odoo/tools/cache.py", line 87, in lookup value = d[key] = self.method(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/odoo/addons/base/ir/ir_model.py", line 1064, in xmlid_lookup raise ValueError('External ID not found in the system: %s' % xmlid) ParseError: "External ID not found in the system: product.product_template_form_view_invoice_policy" while parsing /home/dominic.pain/miningsearchesuk/src/python/msuk_sales/views/views.xml:3, near <record model="ir.ui.view" id="view_product_template_form_inherited"> <field name="name">MSUK view product template form</field> <field name="model">product.template</field> <field name="inherit_id" ref="product.product_template_form_view_invoice_policy"/> <field name="arch" type="xml"> <xpath expr="//field[@name="project_id"]" position="before"> <field name="project_templates"/> </xpath> </field> </record>成员时，生成operator=是没有意义的，因为您无法执行对const成员的分配。

您可以编写自己的，但仍然无法为operator=成员分配值。

为什么删除=运算符，我该如何解决它？
