django - 姜戈。'字符串索引必须是整数，而不是 unicode'

Question

当我在管理站点中运行此操作（向选定的人发送电子邮件）时出现错误：

字符串索引必须是整数，而不是 unicode django在线：[p.user_email])

如何解决？

from django.contrib import admin
from myproject.myapp.models import People
from django.core.mail import send_mail

def send_mail(modeladmin, request, queryset):
    for p in queryset:
        send_mail('People information', p.name, p.time, 'mymail@gmail.com'
    [p.user_email])
send_mail.short_description = u'Send e-mail to selected people'

class PeopleAdmin(admin.ModelAdmin):
    list_display = ('name', 'user_email','time')
    actions = [send_mail]

admin.site.register(People, PeopleAdmin)

Answer 1

实际上，您忘记了 之后的逗号'mymail@gmail.com'，因此将其解释为'mymail@gmail.com'[p.user_email]，就好像您试图索引字符串文字一样。
