views.py

def all_book(request):

    a11_book = Book.objects.all()
    # a11_book = a11_book.encode('utf-8').decode('utf-8')
    # a11_book = a11_book.encode(errors='replace')
    return render(request, 'bookstore/all_book.html', locals())

主路由urls.py

from django.contrib import admin
from django.urls import path, re_path, include
from .import views

urlpatterns = [
     # 数据库查询视图，主路由配分发
    path('bookstore/', include('bookstore.urls'))
]

分支路由bookstore/urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('all_book', views.all_book),
]

没有报错，但网页显示不出数据库的数据，前端页面也只是简单地显示{{ book.id }},没有显示参数值，请各位帮帮忙！

view函数里定义的是a11_book，template里面调用的是all_book啊。。。
把template里面所有all_book改为a11_book应该就可以了
如果有用请采纳 谢谢
