7, Laboratory introduction module
The laboratory profile module is mainly used to introduce the laboratory profile and the basic information of other laboratories of the college, mainly including the laboratory profile of Binhai college, public teaching multimedia laboratory, public computer laboratory, professional laboratory of computer science department, professional laboratory of electronic science department, professional laboratory of economic management department, professional laboratory of foreign language department Professional laboratories of the Department of law and politics, the Department of environmental science and engineering, the Department of art, the Department of finance, and the Department of management science and engineering. The brief introduction of the laboratory of Binhai university mainly introduces the overall situation of the laboratory, and other laboratories are introduced in detail according to the classification of the laboratory. The business module diagram is as follows:

1. Model design
from django.db import models
from DjangoUeditor.models import UEditorField
import django.utils.timezone as timezone
import time
from loginApp.models import BMXXB,RYXXB

Create your models here.

m_y = (time.strftime("%y"))
m_m = (time.strftime("%m"))

Create your models here.

#(3) Laboratory type table (LABLXB)
class LABLXB(models.Model):
LABLXBH = models.CharField('lab type number ', max_length=2,unique=True)
LABLXMC = models.CharField('laboratory type name ', max_length=50)
XH = models.IntegerField('serial number ', default=0)
SYZT = models.IntegerField('usage status', default=0)
CJSJ = models.DateTimeField('creation time ', default = timezone.now)

class Meta:	
	verbose_name = 'Laboratory type maintenance'
	verbose_name_plural = verbose_name
	ordering = ("-CJSJ",)
	
def __str__(self):
	return self.LABLXMC

#(11) Laboratory information sheet (LABXXB)
class LABXXB(models.Model):
LABLXBH = models.ForeignKey('LABLXB ', on_delete=models.CASCADE,verbose_name =' laboratory type number ')
LABBH = models.CharField('lab number ', max_length=50)

2. Migrate (compile) database
python manage.py makemigrations
3. Create database
python manage.py migrate

4. Create super user
python manage.py createsuperuser

5. Background management design

from django.contrib import admin
from .models import *

Register your models here.

class LABXXBAdmin(admin.ModelAdmin):
style_fields = {'LABMS': 'ueditor'}

admin.site.register(LABXXB,LABXXBAdmin)
admin.site.register(LABLXB)
6. View design

from django.shortcuts import render
from .models import *
from django.core.paginator import Paginator
from django.shortcuts import get_object_or_404
from pyquery import PyQuery as pq

def labinfo(request):
lablxs = LABLXB.objects.all().order_by('-XH')
return render(request,'labinfo.html',{'active_menu':'about','lablxs':lablxs,})

def labs(request,newName):
#Resolve the requested news type
lablxs = LABLXB.objects.all().order_by('-XH')
submenu = newName
strname=''
# print(newName)
# if newName == '1':
# strname = '01'
# elif newName == '2':
# strname = '02'
# elif newName == '3':
# strname = '03'
# else:
# strname = '09'
# print(strname)
strname = newName
lablxbh = LABLXB.objects.get(LABLXBH=strname).LABLXBH
# print(lablxbh)
lablxmc = LABLXB.objects.get(LABLXBH=strname).LABLXMC
# print(lablxmc)

labList = LABXXB.objects.all().filter(LABLXBH=lablxbh).order_by('-CJSJ')
for labxx in labList:
    html = pq(labxx.LABMS)  # Parsing html content using pq method
    labxx.mytxt = pq(html)('p').text()  # Intercept html paragraph text
# paging
p = Paginator(labList, 5)
if p.num_pages <= 1:
    pageData = ''
else:
    page = int(request.GET.get('page', 1))
    labList = p.page(page)
    left = []
    right = []
    left_has_more = False
    right_has_more = False
    first = False
    last = False
    total_pages = p.num_pages
    page_range = p.page_range
    if page == 1:
        right = page_range[page:page + 2]
        print(total_pages)
        if right[-1] < total_pages - 1:
            right_has_more = True
        if right[-1] < total_pages:
            last = True
    elif page == total_pages:
        left = page_range[(page - 3) if (page - 3) > 0 else 0:page - 1]
        if left[0] > 2:
            left_has_more = True
        if left[0] > 1:
            first = True
    else:
        left = page_range[(page - 3) if (page - 3) > 0 else 0:page - 1]
        right = page_range[page:page + 2]
        if left[0] > 2:
            left_has_more = True
        if left[0] > 1:
            first = True
        if right[-1] < total_pages - 1:
            right_has_more = True
        if right[-1] < total_pages:
            last = True
    pageData = {
        'left': left,
        'right': right,
        'left_has_more': left_has_more,
        'right_has_more': right_has_more,
        'first': first,
        'last': last,
        'total_pages': total_pages,
        'page': page,
    }
# print(lablxs)
# print(labList)
return render(
    request, 'labList.html', {
        'active_menu': 'labs',
        'sub_menu': submenu,
        'lablxmc': lablxmc,
        'lablxs':lablxs,
        'labList': labList,
        'pageData': pageData,
    })

def labDetail(request, id):
lablxs = LABLXB.objects.all().order_by('-XH')

mylab = get_object_or_404(LABXXB, id=id)
mylab.VIEWS += 1
mylab.save()
print(mylab)
return render(request, 'labDetail.html', {
    'active_menu': 'labs',
    # 'lablxmc': lablxmc,
    'lablxs':lablxs,
    'mylab': mylab,
})

7. Access routing design
from django.urls import path
from . import views

app_name = 'aboutApp'

urlpatterns = [
path('labinfo / ', views.labinfo, name =' labinfo '), # lab overview
path('labs/str:newName / ', views.labs, name =' Labs'), # lab list
path('labDetail/int:id / ', views.labDetail, name =' labDetail '), # lab details
]
8. Introduction to laboratory template design

{% extends "base.html" %}
{% load static %}

{% block title %}
Introduction to the laboratory of Binhai University
{% endblock %}

{% block content %}

{% endblock%} 9. Template design of laboratory information list

{% extends "base.html" %}
{% load static %}

{% block title %}
{{lablxmc}}
{% endblock %}

{% block content %}

{% endblock %}

10. Laboratory details and formwork design
{% extends "base.html" %}
{% load static %}
{% block title %}
{{mylab.LABLXBH}}
{% endblock %}
{% block content %}

{% endblock %}
