快速迭代完善应用

设置Django Admin模型显示的字段

class JobAdmin(admin.ModelAdmin):list_display = ("job_name", "job_type", "job_city", "creator", "created_date", "modified_date")admin.site.register(JobAdmin)

设置Django Admin新增/修改时不需要手动编辑的字段

class JobAdmin(admin.ModelAdmin):exclude = ("creator", "created_date", "modified_date")
admin.site.register(JobAdmin)

设置Django Admin创建/修改人为当前登录用户

class JobAdmin(admin.ModelAdmin):def save_model(self, request, obj, form, change):obj.creator = request.usersuper().save_model(request, obj, form, change)
admin.site.register(Job, JobAdmin)

添加自定义页面

• 列表页时独立页面，使用自定义的页面
• 添加如下页面
  • 职位列表页
  • 职位详情页
• 匿名用户可以访问
