Save（）不使用Codeigniter更新DataMapper中表中的數據

Question

嗨，我是Codeigniter的新手，我已經編寫了代碼來更新一個表數據，但是它在數據庫表中沒有更新，並且是火插入查詢而不是update。

這是我的控制器方法客戶是表

public function editClients($id="")
        {
            Auth::RequireFleetindia();
            $this->template->set("fleet_india");
            $this->template->setData("SelectedTab", "Clients");

            $this->Clientsedit = new Clients();
            $this->Clientsedit->where(array("account_id"=> Auth::get("id"),'ID'=>$id))->get();

            if(isset($_POST['Submit']))
            {   echo $this->Clientsedit->ID;
                $this->load->library('form_validation');
                $this->form_validation->set_rules('clientname', 'Client Name', 'required');
                $this->form_validation->set_rules('address', 'Address', 'required');
                $is_unique='';
                if($this->input->post('clientemail') != $this->Clientsedit->email) 
                {
                       $is_unique =  '|is_unique[clients.email]';

                } 
                $this->form_validation->set_rules('clientemail', 'Client Email', 'required|valid_email'.$is_unique);

                $this->form_validation->set_rules('daily_rate', 'Daily Rate', 'numeric');
                $this->form_validation->set_rules('daily_contract_mileage', 'Daily Contract Mileage', 'numeric');
                $this->form_validation->set_rules('excess_mileage_rate', 'Excess Mileage Rate', 'numeric');
                $this->form_validation->set_rules('daily_contract_time', 'Daily Contract Time', 'numeric');
                $this->form_validation->set_rules('overtime_rate', 'Overtime_Rate', 'numeric');
                $this->form_validation->set_rules('night_shift_rate', 'Night Shift Rate', 'numeric');
                $this->form_validation->set_rules('overtime_incentives', 'Overtime Incentives', 'numeric');
                $this->form_validation->set_rules('taxrate1', 'Tax Rate', 'numeric');
                $this->form_validation->set_rules('taxrate2', 'Tax Rate', 'numeric');



                if($this->form_validation->run() != FALSE)
                {
                    $this->Clientsedit->client_name             =   $this->input->post('clientname');
                    $this->Clientsedit->address                 =   $this->input->post('address');
                    $this->Clientsedit->email                   =   $this->input->post('clientemail');
                    $this->Clientsedit->daily_rate              =   $this->input->post('daily_rate');
                    $this->Clientsedit->daily_contract_mileage  =   $this->input->post('daily_contract_mileage');
                    $this->Clientsedit->excess_mileage_rate     =   $this->input->post('excess_mileage_rate');
                    $this->Clientsedit->daily_contract_time     =   $this->input->post('daily_contract_time');
                    $this->Clientsedit->overtime_rate           =   $this->input->post('overtime_rate');
                    $this->Clientsedit->night_shift_rate        =   $this->input->post('night_shift_rate');
                    $this->Clientsedit->overtime_incentives     =   $this->input->post('overtime_incentives');
                    $this->Clientsedit->taxrate1                =   $this->input->post('taxrate1');
                    $this->Clientsedit->taxrate2                =   $this->input->post('taxrate2');


                    if($this->Clientsedit->save())
                    {
                        echo '<pre>';
                        print_r($this->Clientsedit);
                        echo '</pre>';
                        $this->session->set_flashdata('msg', 'Client Updated');
                        //redirect("fleet_india_client/editClients","refresh");
                    }
                    else
                    {
                        $error = $this->Clientsedit->error->string;
                        echo $error;
                        echo $this->Clientsedit->address ;
                        //redirect("fleet_india_client/editClients","refresh");
                    }

                }
                else
                {
                    //$this->load->view("fleet_india/clients/editClients");
                }
            }
            else

我發現錯誤是數據庫中的表存在問題。 我尚未將主鍵設置為id，這就是為什么它不更新需要為要使用數據映射器更新表中任何記錄的字段設置主鍵的原因。

感謝大家的評論。
