太好了，老师说的非常详实，还有原代码对比，在CSDN还有极客报了好几个课程，到目前第一次能够体验了“跟上课程”的感觉，泪目( Ĭ ^ Ĭ )，谢谢老师。

为什么评论都不回复

老师，在views.py文件中 for job in job_list: job.city_name = Cities[job.job_city] job.type_name = JobTypes[job.job_type] 上边循环里头，两边的job是同一个对象么？

和老师代码一样 但是提示找不到joblist.html

你好老师,我按照你写的html代码以及view.py,urls.py(两个),也重启了服务,但是打开joblist页面提示Server Error,可以打开admin页面,下面是我在本节新增改动的内容,麻烦你看看帮忙解答一下,谢谢. jobs/templates/base.html <!-- base.html --> <h1 style="margin:auto;width:50%;">字节科技开放职位</h1> <p></p> {% block content %} {% endblock %} jobs/templates/joblist.html {% extends 'base.html' %} {% block content %} 终于等到你,期待加入我们,用技术去探索一个新世界 {% if job_list %} <ul> {% for job in job_list %} <li>{{job.type_name}} <a href="/job/{{ job.id }}/" style="color:bule">{{ job.job_name }}</a> {{job.city_name}} </li> {% endfor %} </ul> {% else %} <p>No jobs are available.</p> {% endif %} {% endblock %} {% endblock %} jobs/urls.py from django.conf.urls import url from jobs import views urlpatterns = [ # 职位列表 url(r"^joblist/", views.joblist, name="joblist") ] jobs/views.py from django.shortcuts import render # Create your views here. from django.template import loader from django.http import HttpResponse from jobs.models import Cities, JobTypes from jobs.models import Job def joblist(request): job_list = Job.objects.order_by('job_type') template = loader.get_template('joblist.html') context = {'job_list': job_list} for job in job_list: job.city_name = Cities[job.job_city][1] job.job_type = JobTypes[job.job_type][1] return HttpResponse(template.render(context)) recruitment/urls.py from django.conf.urls import url, include from django.contrib import admin from django.urls import path, re_path from django.views.static import serve from recruitment.settings import STATIC_ROOT urlpatterns = [ url(r"^", include('jobs.urls')), path('admin/', admin.site.urls), re_path('static/(?P<path>.*)', serve, {'document_root': STATIC_ROOT}), ]

老师 我的html渲染城市和职位类型还是显示数字 是什么原因呢 views.py from Jobs.models import Job,JobType,JobCity from django.shortcuts import render from django.template import context, loader from django.http.response import HttpResponse # Create your views here. def joblist(request): job_list = Job.objects.order_by('job_type') template = loader.get_template('job_list.html') for job in job_list: job_city = JobCity[job.job_city][-1] job_type = JobType[job.job_type][-1] print(job) context = { 'job_list':job_list } return HttpResponse(template.render(context)) job_list.html {% extends 'base.html' %} {% block content %} 终于等到你，期待你的加入，一起去探索一个新的世界 {% if job_list %} <ul> {% for job in job_list %} <li>{{ job.job_type }} <a href="/job/{{ job.id }}" style="color: blue">{{ job.job_title }}</a> {{ job.job_city }}</li> {% endfor %} </ul> {% else %} <p>暂无开放的职位列表</p> {% endif %} {% endblock %}

吕老师为什么我第七课完全照着您的代码，可是最终页面并没显示职位的内容？只是显示了默认值

老师您好，在最好的页面展示中我这边实际效果在在页面中并没能顺利输出职务内容，而是 输出了 “No jobs are available” 默认值。应该是job_list 的值没能顺利传入至html中。已经检查了python代码 views.py, 在文件里面是顺利取到了job_list. views.py from django.shortcuts import render # Create your views here. from django.shortcuts import render from django.http import HttpResponse from django.template import loader from jobs.models import Cities, JobTypes from jobs.models import Job def joblist(request): job_list = Job.objects.order_by('job_type') template = loader.get_template('joblist.html') context = {'lob_list': job_list} for job in job_list: job.job_type = JobTypes[job.job_type][1] print(job.job_type) job.city_name = Cities[job.job_city][1] print(job.city_name) return HttpResponse(template.render(context)) base.html <!--jobs/templates/base.html--> <!-- base.html--> <h1 style="margin:auto;width:50%;">招聘招聘</h1> <p></p> {% block content %} {% endblock %} joblist.html {% extends 'base.html' %} {% block content %} 终于等到你, 期待加入. {% if job_list %} <ul> {% for job in job_list %} {% comment %} <li>{{job.type_name}} <a href="/job/{{ job.id }}/" style="color:blue">{{ job.job_name }}</a> {{job.city_name}} </li> {% endcomment %} <li>{{job.type_name}} <a href="/job/{{ job.id }}/" style="color:blue">{{ job.job_name }}</a> {{job.city_name}} </li> {% endfor %} </ul> {% else %} <p>No jobs are available</p> {% endif %} {% endblock %}

django 的自定义模版中写{%%},跟以前jsp一样，太难看了。写页面还是得用前端框架比较好。

请问一下老师，为按照老师这个代码自己另外写了一个应用，大部分代码都是没变，只是有些变量和一些名称变了，但是在调用objects.order_by这个方法的时候出错，我写的那个class不能调用，提示local variable 'XXX' referenced before assignment.
