如何从 Django 管理员触发芹菜任务?

Question

>我有一个名为Publication的模型，我想在 Django Admin 中的列表视图中添加一个按钮，该按钮将允许触发 Celery 任务。

admin.py：

from django.contrib import admin
from .models import Publication

class PublicationAdmin(admin.ModelAdmin):
change_list_template = "variants/admin_publication_list.html"
def update(self, request):
# trigger task
# redirect to admin list
admin.site.register(Publication, PublicationAdmin)

variants/admin_publication_list.html：

{% extends 'admin/change_list.html' %}
{% block object-tools %}
<li>
<a href="/admin/variants/publication/update/">
Update
</a>
</li>
{{ block.super }}
{% endblock %}

但是，当我按下按钮时，我只收到通知：

ID 为"update"的发布不存在。也许它被删除了？

方法名称update或路由名称update过于通用，有时被框架自动使用，请尝试命名它以匹配您的功能。revoke-publications或sync-publications.

admin.py：

from django.contrib import admin
from django.urls import path
from django.http import HttpResponseRedirect
from .models import Publication
from .tasks import your_celery_task
@admin.register(Publication)
class PublicationAdmin(admin.ModelAdmin):
change_list_template = "variants/admin_publication_list.html"
def get_urls(self):
urls = super().get_urls()
my_urls = [
path('update-publications/', self.publication_update),
]
return my_urls + urls
def publication_update(self, request):
result = your_celery_task.delay("some_arg")
self.message_user(
request,
f"Task with the ID: {result.task_id} was added to queue. Last known status: {result.status}"
)
return HttpResponseRedirect("../")

variants/admin_publication_list.html：

{% extends 'admin/change_list.html' %}
{% block object-tools %}
<div>
<form action="update-publications/" method="POST">
{% csrf_token %}
<button type="submit">Run Celery Task</button>
</form>
</div>
<br />
{{ block.super }}
{% endblock %}
