Django 从 1.2.5 升级到 1.3 admin 报错

Question

我正在尝试升级网站运行 django 1.2.5 到 1.3 到目前为止我遇到的唯一错误是在网站的管理部分：

__init__() got an unexpected keyword argument 'field_path'

我认为来自这段代码中的某处：

class EventAdmin(admin.ModelAdmin):
    inlines = [EventArtistsInline, EventGalleryInline, EventRelatedObjectInline, EventPriceInline, SeriesPassInline, EventsInSeriesInline, ]
    save_as = True
    prepopulated_fields = {"slug": ("prefix", "title", "suffix")}
    list_filter = ('start_date', 'is_series')
    search_fields = ['title', 'description', 'intro',]

    def changelist_view(self, request, extra_context=None):
        if request.user.is_superuser:
            self.list_display_links = ['title']
            self.list_display= ['title', 'status', 'start_date', 'end_date', 'hide_artists', 'featured', 'is_series', 'tickets_sold', 'tickets_remaining', 'sold_out']
            self.list_editable = ['featured', 'status', 'hide_artists', 'is_series','sold_out',]
        else:
            self.list_display_links = ['']
            self.list_display= ['title', 'status', 'start_date', 'tickets_sold', 'tickets_remaining', 'sold_out']
            self.list_editable = ['status']
        return super(EventAdmin, self).changelist_view(request, extra_context)

    class Media:
        js = [
            settings.MEDIA_URL+'tiny_mce/tiny_mce.js',
            settings.MEDIA_URL+"filebrowser/js/TinyMCEAdmin.js",
        ]

我该如何解决这个问题？

Answer 1

很难说到底哪里出了问题。

错误是在名为 filterspecs.py 的文件中触发的。我怀疑这可能是因为您有一个未包含在 self.list_display 中的列表过滤器 is_series。

尝试注释掉 list_filter 行，看看是否有任何改变。

list_filter = ('start_date', 'is_series')
self.list_display= ['title', 'status', 'start_date', 'tickets_sold', 
                    'tickets_remaining', 'sold_out']

也可能是后来的django版本修复了一些bug。由于 admin.py 个文件是可选的，您可以在升级过程中删除或重命名它们，直到解决其他问题为止。此错误可能是由更高版本的 django 中修复的问题引起的。

Answer 2

实际上是 start_date 字段导致了问题，我在 models.py 文件中的过滤器 class 中找到了这个 models.py ，并得到了一些帮助 post:

django admin custom list_filter
