[英]readonly_fields returns empty value in django inlined models
i am new in django framework, in my current try, i have two models (Client and Facture). 我是django框架的新手,在我目前的尝试中,我有两个模型(客户端和Facture)。 Facture is displayed as a TabularInline in client change view. 在客户端更改视图中,外观以TabularInline的形式显示。
i want display a link for each inlined facture object to download the file. 我想为每个内联的制造对象显示一个链接以下载文件。 so i added a custom view that download the facture file, but dont know how to link to it 所以我添加了一个自定义视图,该视图下载了制造文件,但是不知道如何链接到该文件
class Client(models.Model):
...
class Facture(models.Model):
client = models.ForeignKey(Client, on_delete=models.CASCADE)
numero = models.IntegerField(unique=True, default=rand_code)
...
and in the admin.py: 并在admin.py中:
class FactureInline(admin.TabularInline):
model = Facture
extra = 0
readonly_fields = ('numero', 'dl_link')
def DLFacture(self, request, obj):
...
response.write(pdf)
return response
def get_urls(self):
urls = super(FactureAdmin, self).get_urls()
from django.conf.urls import url
download_url = [
url(r'^(?P<pk>\d+)/download/$', self.admin_site.admin_view(self.DLFacture), name="download"),
]
return download_url + urls
def dl_link(self, obj):
from django.core.urlresolvers import reverse
return reverse("admin:clients_facture_download", args=[obj.pk])
admin.site.register(Facture, FactureAdmin)
class ClientAdmin(admin.ModelAdmin):
inlines = [
FactureInline,
]
admin.site.register(Client, ClientAdmin)
i get the following error: 我收到以下错误:
Reverse for 'clients_facture_download' with arguments '(1,)' and keyword arguments '{}' not found. 0 pattern(s) tried: []
all works fine when i change the reverse url to 当我将反向网址更改为时,一切正常
reverse("admin:clients_facture_change", args=[obj.pk])
so any one could help me know how to reverse the download view and if i am doing thinks right ? 所以任何人都可以帮助我知道如何反转下载视图,并且如果我在做的话认为正确吗?
thanks for any help 谢谢你的帮助
I would think you need to reverse the order in the url: 我认为您需要颠倒网址中的顺序:
url(r'^download/(?P<pk>\d+)$', self.admin_site.admin_view(self.DLFacture), name="download"),
]
Firstly, you are using name='download'
, but trying to reverse clients_facture_download
. 首先,您使用的是name='download'
,但尝试撤消clients_facture_download
。
I would try changing the url from 我会尝试从更改网址
url(r'^(?P<pk>\d+)/download/$', self.admin_site.admin_view(self.DLFacture), name="download"),
to 至
url(r'^(?P<pk>\d+)/download/$', self.admin_site.admin_view(self.DLFacture), name="clients_fracture_download"),
Secondly, InlineModelAdmin does not have a get_urls
method. 其次,InlineModelAdmin 没有 get_urls
方法。 You should move it to your ClientAdmin
class. 您应该将其移至ClientAdmin
类。
