Django 批量保存图片文件 自定义上传方法

1.前端通过formData的方式批量增加图片或文件

        for (var i = 0; i < form_img_list.length; i++) {
            formData.append('image_file', form_img_list[i]);
        }

 

AJAX写法

    $('#submit_save_b').click(function (e) {
        //formData 增加值
        e.preventDefault()
        console.log(form_img_list,33333);
        for (var i = 0; i < form_img_list.length; i++) {
            formData.append('image_file', form_img_list[i]);
        }

        formData.append('advertiser', $('#base_username_id').text());
        formData.append('campaign_name', $('#adv_name_value').val());
        formData.append('campaign_id', $('#adv_plan_value').val());
        formData.append('data', $('#adv_des_value').val());
        formData.append('title', $('#adv_title_value').val());
        formData.append('ad_imp_type', $('#ad_imp_type').val());
        formData.append('landing_url', $('#adv_landing_value').val());
        formData.append('enable', 1);
        formData.append('remove_img_list', remove_img_list);

        console.log(formData);

        var checkText = $("#id_select_ad_campaing").find("option:selected").text();
        if (checkText == '请选择广告计划：') {
            alert('请选择广告计划');
            return false;
        }

        var csrftoken = getCookie('csrftoken');
        $.ajax({
            cache: false,
            type: 'POST',
            data: formData,
            url: '/advertisement_list/',
            traditional: true, //为必须内容 　　
            //dataType:'json', //data为json时必须
            processData: false, //为必须内容
            contentType: false, //为必须内容
            success: function (data, textStatus, jqXHR) {
                console.log(data);
                if (jqXHR.status == 201) {
                    $('.page-content').fadeOut(300,function(){
                        $('.center').fadeIn(300)
                    })
                    show_list_table();
                    $('#Adver_Cell_Modal').modal('hide');
                    form_ad_campaing_reset();
                }

            },
            beforeSend: function (xhr, settings) {
                xhr.setRequestHeader("X-CSRFToken", csrftoken);
            },
            error:function(data){
                console.log(222)
            }
        });
    });
