django-import-export 显示model verbose_name
安装并配置django-import-export
pip install django-import-export pip install django-simpleui
配置settings.py
# settings.py
INSTALLED_APPS = (
'simpleui',
'import_export',
)
建立model
from django.db import models # Create your models here. # 商品表 class commodity(models.Model): name = models.CharField(max_length=225, verbose_name="商品名称", blank=True, default="") desc = models.TextField(verbose_name="商品描述", blank=True) class Meta: verbose_name_plural = "商品表" def __str__(self): return self.name
生成数据库迁移
python manage.py makemigrations
python manage.py migrate
配置 admin.py
from django.contrib import admin from app import models from import_export import resources from import_export.admin import ImportExportModelAdmin from django.apps import apps admin.site.site_header = "XXX后台管理" admin.site.site_title = "XXX后台" # Register your models here. class commodityResource(resources.ModelResource): def __init__(self): super(commodityResource, self).__init__() field_list = models.commodity._meta.fields self.vname_dict = {} for i in field_list: self.vname_dict[i.name] = i.verbose_name # 默认导入导出field的column_name为字段的名称，这里修改为字段的verbose_name def get_export_fields(self): fields = self.get_fields() for field in fields: field_name = self.get_field_name(field) # 如果我们设置过verbose_name，则将column_name替换为verbose_name。否则维持原有的字段名 if field_name in self.vname_dict.keys(): field.column_name = self.vname_dict[field_name] return fields def after_import(self, dataset, result, using_transactions, dry_run, **kwargs): print("after_import") def after_import_instance(self, instance, new, **kwargs): print("after_import_instance") class Meta: model = models.commodity skip_unchanged = True report_skipped = True fields = ("id", "name", "desc") @admin.register(models.commodity) class AppTypeAdmin(ImportExportModelAdmin): list_display = ("name", "desc") list_display_links = ("name", "desc") search_fields = ('name', 'desc') model_icon = "fa fa-tag" list_per_page = 50 resource_class = commodityResource def save_model(self, request, obj, form, change): super().save_model(request, obj, form, change)
运行效果图如下:
点击导入页面如下:
实现思路如下:
通过重写导入页面,在应用目录(app)下-->templatetags-->apptags.py
配置settings.py
libraries 节点
TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')] , 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], 'libraries': { 'apptags': 'app.templatetags.apptags' }, }, }, ]
apptags.py
from django import template from django.apps import apps register = template.Library() # 这一句必须这样写 @register.simple_tag(takes_context=True) def import_head_tag(context): verbose_names = [] fieldlists = context.dicts[3]["fields"] opts = str(context.dicts[3]["opts"]).split(".") for f in fieldlists: fields = apps.get_model(opts[0], opts[1])._meta.fields for fs in fields: if (str(fs).split(".")[-1] == str(f)): verbose_names.append(fs.verbose_name) break return "，".join(verbose_names)
重写django-import-export 导入页面,在项目templates下新建 admin-->import_export--> import.html
import.html代码如下 将{{ fields|join:", " }} 替换成 apptags.py 定义的 import_head_tag 方法即可
