Question

我正在为公司网站实施新闻通讯应用程序。我的目标是允许“未来”网站管理员直接从管理员处发布新闻稿。

为此，我编写了以下代码：

models.py

from django.db import models
from ckeditor.fields import RichTextField

class NewsletterSubscription(models.Model):
    datetime = models.DateTimeField(auto_now_add = True)
    email = models.EmailField(max_length=128)

    class Meta:
        verbose_name = 'Iscritto Newsletter'
        verbose_name_plural = 'Iscritti Newsletter'

    def __unicode__(self):
        return self.email

class Newsletter(models.Model):
    EMAIL_STATUS_CHOICES = (
        ('Draft', 'Draft'),
        ('Pubblicata', 'Pubblicata')
    )
    subject = models.CharField(max_length=250)
    body = RichTextField()
    email = models.ManyToManyField(NewsletterSubscription)
    status = models.CharField(max_length=10, choices=EMAIL_STATUS_CHOICES)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

    def __unicode__(self):
        return self.subject

我想知道是否可以在 NewsletterAdminForm 中添加一种按钮，该按钮可以触发电子邮件。

admin.py

from django import forms
from django.contrib import admin
from .models import NewsletterSubscription, Newsletter
from ckeditor.widgets import CKEditorWidget

class NewsletterSubscriptionAdmin(admin.ModelAdmin):
    list_display = ('email', 'datetime', )

class NewsletterAdminForm(forms.ModelForm):
    body = forms.CharField(widget=CKEditorWidget())
    class Meta:
        model = Newsletter
        fields = '__all__'

class NewsletterAdmin(admin.ModelAdmin):
    form = NewsletterAdminForm

admin.site.register(NewsletterSubscription, NewsletterSubscriptionAdmin)
admin.site.register(Newsletter, NewsletterAdmin)

在此先感谢您提供的帮助。

要在管理面板中获取按钮，您只需创建一个方法即可返回html：

class NewsletterAdmin(admin.ModelAdmin):
    ...

    readonly_fields = ['send_mails']

    def send_mails(self, obj):
        url_red = 'url_of_your_view_to_send_mails'
        return format_html(
            '<a class="button" href="{}">Send</a>&nbsp;',
            url_red,
        )

然后将其渲染为管理页面中的按钮，该页面会将GET请求发送到视图提供的url，您可以在其中定义所有逻辑并发送邮件。请将此自定义字段包含在 fields 属性中。

希望有帮助。
