Question

django的新手。我试图修改模型以在同一行上获得2个字段。阅读关于https://docs.djangoproject.com/en/2.1/ref/contrib/admin/的文档之后我在admin.py中尝试了以下操作：

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News和NewsDisplay，因为它们可以正常工作。

将NewsAdd添加到admin.site.register（）后，立即出现以下错误：

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

我敢肯定，我在这里遗漏了一些非常简单的东西，但是不能靠我自己解决。有人可以帮忙吗？

这应该是单个ModelAdmin类。

admin.site.register有两个参数：Model类和适当的ModelAdmin类。您正在尝试传递三个非法的参数。

list_display，search_fields和fieldsets可以合并为一个类定义。

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)

如何使用字段集而不会引起Registry（）错误？
