python - 向 django-cms 添加自定义占位符

Question

我正在尝试创建自定义占位符以在网站上添加管理员可编辑的部分。 Django-cms' documentation对于添加它要做什么是非常通用的。

占位符存在于名为联系人 的单独应用中，该应用已添加到settings.py 文件

这是我到目前为止的代码(跳过导入以减少冗长):

模型.py

class ContactsPlaceholder(models.Model):
    phone = models.CharField(max_length=100)
    email = models.CharField(max_length=100)
    address = models.TextField(max_length=700)
    # your fields
    my_placeholder = PlaceholderField('contacts_contactsplaceholder')
    # your methods

    def __unicode__(self):
        return "Contacts Placeholder"

views.py

def contacts(request):
  # Load the the contacts from db
  contactsfields = ContactsField.objects.all()
  contacts_placeholder = ContactsPlaceholder.objects.all() 
  context = {"contactsfields" : contactsfields, "contacts_placeholder" : contacts_placeholder}
  return render(request, "../templates/contacts.html", context) 

def contacts_placeholder_detail(request, id): # is this really useful?
  object = get_object_or_404(ContactsPlaceholder, id=id)
  return render_to_response('../templates/contacts_placeholder_detail.html', {
      'object': object,
  }, context_instance=RequestContext(request))

contacts.html

{% extends "base.html" %}
{% load cms_tags %}
{% block content %}
<div>
  <h1>Contacts</h1>

  {% placeholder "contacts_placeholder" or %}
   <p>Placeholder is empty</p>
  {% endplaceholder %}
</div>
{% endblock content %}

最后，admin.py

class ContactsPlaceholderAdmin(PlaceholderAdminMixin, admin.ModelAdmin):
    # Editable fields
    frontend_editable_fields = ("phone", "email", "address")
    # Form fields order and sections
    fieldsets = [
        (None,{"fields" : ["phone", "email", "address"]})
    ]

admin.site.register(ContactsPlaceholder, ContactsPlaceholderAdmin)

使用此配置，运行后

python manage.py syncdb

I do get "Placeholder is empty" in the html response, and of course the placeholder is not editable using the standard frontend editor, which was the desired behaviour.

Going to 127.0.0.1:8000/admin/ i can see the "Contacts Placeholder" table, however when I click it or try to add items I do get the following error:

OperationalError at /us/admin/contacts/contactsplaceholder/
no such column: contacts_contactsplaceholder.phone

如果contacts() View 通过应用程序钩子(Hook)呈现，然后使用 {% placeholder "contacts_placeholder" %}在模板中将不起作用。

在通过 AppHook 连接到 CMS 的应用程序中使用占位符时，您必须使用 {% static_placeholder "MyPlaceholder" %}而不是通常的 {% Placeholder "MyPlaceholder" %}

如果您有一个应用程序或插件，您在其中创建了一个 PlaceholderField，那么在呈现它的模板中，您需要以下标记；

{% render_placeholder instance.placeholderfieldname %}
