我试图在不刷新页面的情况下添加喜欢/不喜欢的功能，但是我无法设置逻辑 这是我的models.py文件代码
from django.db import models
# Create your models here.
class EmployeeDetail(models.Model):
emp_fname = models.CharField(max_length=50, default="")
emp_lname = models.CharField(max_length=50, default="")
emp_uname = models.CharField(max_length=100, default="")
emp_email = models.EmailField(max_length=254, default="")
emp_password = models.CharField(max_length=100, default="")
emp_dob = models.DateField(max_length=50, default="")
emp_doj = models.DateField(max_length=50, default="")
emp_designation = models.CharField(max_length=100, default="")
emp_salary = models.IntegerField()
emp_leaves = models.IntegerField()
emp_contact = models.CharField(max_length=12, default="")
emp_photo = models.ImageField(upload_to="employee/images", default="")
def __str__(self):
return self.emp_fname
class Post(models.Model):
emp_id = models.ForeignKey(EmployeeDetail, on_delete=models.CASCADE)
title = models.CharField(max_length=255)
slug = models.CharField(max_length=150)
content = models.TextField()
author = models.CharField(max_length=15)
timeStamp = models.DateTimeField(auto_now_add=True)
likes = models.IntegerField(default=0)
dislikes = models.IntegerField(default=0)
def __str__(self):
return self.title + ' by ' + self.author
class Preference(models.Model):
user_id = models.ForeignKey(EmployeeDetail, on_delete=models.CASCADE)
post_id = models.ForeignKey(Post, on_delete=models.CASCADE)
value = models.IntegerField()
date = models.DateTimeField(auto_now_add=True)
def __str__(self):
return str(self.user_id) + ':' + str(self.post_id) + ':' + str(self.value)
我的urls.py代码在这里吹
from django.urls import path
from .import views
urlpatterns = [
path('', views.login, name='Login'),
path('logout', views.logout, name='Logout'),
path('employee/home/', views.home, name='Home'),
path('employee/manageuser/', views.manageuser, name='manageuser'),
path('employee/blank/', views.blank, name='blank'),
path('employee/font_awesome/', views.font_awesome, name='fontawesome'),
path('employee/map_google/', views.map_google, name='map google'),
path('employee/not_found/', views.not_found, name='map google'),
path('employee/register/', views.register, name='Registration'),
path('employee/employee_profile/<int:id>', views.employee_profile, name='Employee Profile'),
path('employee/delete_employee/<int:id>', views.delete_employee, name='Delete Employee'),
path('employee/edit_employee/<int:id>', views.edit_employee, name='Edit Employee'),
path('employee/create_post/', views.create_post, name='Create Post'),
path('employee/blogpost/<slug:slug>', views.blogpost, name='Blog Post'),
path('employee/blogpost/<int:post_id>/preference/userpreference', views.postpreference, name='postpreference')
]
我在这里看到了views.py文件代码
from django.shortcuts import render, redirect
from .models import EmployeeDetail, Post, Preference
from django.http import HttpResponse
from django.contrib import messages
# Create your views here.
def create_post(request):
if request.session.has_key('emp_uname'):
name = request.session['emp_uname']
query = EmployeeDetail.objects.filter(emp_uname=name)
if request.method == "POST":
title = request.POST.get('title')
slug = request.POST.get('slug')
eid = request.POST.get('eid')
euname = request.POST.get('ename')
content = request.POST.get('content')
empid = EmployeeDetail.objects.get(id=eid)
post = Post(emp_id=empid, title=title, slug=slug, content=content, author=euname)
# print(post.emp_id.id)
post.save()
return redirect('/employee/home')
else:
return render(request, 'create_post.html', {'query': query})
else:
messages.error(request, 'You have to login First')
return redirect('/')
def blogpost(request, slug):
if request.session.has_key('emp_uname'):
name = request.session['emp_uname']
query = EmployeeDetail.objects.filter(emp_uname=name)
postslug = Post.objects.filter(slug=slug)
return render(request, 'blogpost.html', {'postslug': postslug, 'query': query})
else:
messages.error(request, 'You have to login First')
return redirect('/')
def postpreference(request, postid):
return render(request, 'blogpost.html', context)
并且我在这里有blogpost.html文件，该页面中还包含特定的博客详细信息和“喜欢/不喜欢”链接，当有人喜欢/不喜欢这里的详细代码时，我不想刷新此页面
