我有一個管理操作,從我的數據庫中打開一個pdf對象,並更新與該行關聯的某些字段。我將如何讓管理頁面在執行操作後自動顯示對這些字段的更改,就像預安裝的刪除管理操作一樣?我已經嘗試過使用HttpResponseRedirect作爲解決方法,但一直未能與我的響應對象一起工作 - 只有一個或另一個工作。有沒有簡單的方法讓頁面自動刷新?預先感謝任何指導!Django自定義管理操作自動更新/刷新管理頁面
from django.contrib import admin
from django.contrib.auth.models import User
from djangostuff.pdf.models import ABC
from django.http import HttpResponse, HttpResponseRedirect
import datetime, time
class ABCAdmin(admin.ModelAdmin):
actions = ['print_selected_pdf']
def get_user(self):
return '%s'%(self.user.username)
def create_pdf(self, request, queryset):
response = HttpResponse(mimetype="application/pdf")
response['Content-Disposition'] = 'attachment; filename=form.pdf'
for obj in queryset:
response.write(obj.form)
rows_updated = ABC.objects.filter(pk=obj.pk).update(user=request.user,pdf_printed="1",request_time=time.strftime("%H:%M:%S"),request_date=datetime.datetime.today())
if rows_updated == 1:
message_bit = "1 form was"
else:
message_bit = "%s forms were" % rows_updated
self.message_user(request, "%s successfully printed." % message_bit)
return response
#HttpResponseRedirect("/admin/pdf/abc")
def print_selected_pdf(self, request, queryset):
# prints the pdfs for those that are selected,
# regardless if the pdf_printed field is true or false
qs = queryset.filter(pdf_printed__exact=0)
return self.create_pdf(request, qs)
print_selected_pdf.short_description = "Print Selected PDF"
get_user.short_description='Printed By'
list_display=('form_no',get_user,'request_date','request_time','pdf_printed')
admin.site.register(ABC, ABCAdmin)
