如何使用字段集而不会引起注册表()错误

Question

django新的。我试图修改模型以在同一行上获得2个字段。阅读了https://docs.djangoproject.com/en/2.1/ref/contrib/admin/之后我在admin.py中尝试了以下内容：

from django.contrib import admin
from .models import *

# Register your models here.
class NewsAdd(admin.ModelAdmin):
    fieldsets = [
        (None, {
            'fields': ('field1'('field2','field3'),'field4','field5','field6','field7')})]
class NewsDisplay(admin.ModelAdmin): 
    list_display = ('nick','hosty','msg','info','specjalista','od','do') 
    search_fields = ('nick','hosty','msg','info','specjalista','od','do') 
admin.site.register(News, NewsDisplay, NewsAdd)

请不要介意admin.Site.Register中的新闻和新闻播放。

一旦将newsadd添加到admin.Site.Register（），我会收到以下错误：

    admin.site.register(News, NewsDisplay, NewsAdd)
TypeError: register() takes from 2 to 3 positional arguments but 4 were given

我敢肯定，我在这里错过了一些非常简单的东西，但无法独自解决。任何人请帮助？

这应该是一个ModelAdmin类。

admin.site.register有两个参数：Model类和适当的ModelAdmin类。您正在尝试通过三个非法的论点。

list_display，search_fields和fieldsets可以在单个类别定义中组合。

class NewsAdmin(admin.ModelAdmin):
    fieldsets = [
        (None, {
            'fields': ('field1'('field2','field3'),'field4','field5','field6','field7')})]
    list_display = ('nick','hosty','msg','info','specjalista','od','do') 
    search_fields = ('nick','hosty','msg','info','specjalista','od','do') 
admin.site.register(News, NewsAdmin)
