django-admin（day1）

提供一个学员管理系统，有一个前台页面展示现有学员，并供新学员提交申请，一个后台负责处理。

django在渲染前端页面时，会根据settings.py中的APP的顺序查找templates，如果不同的app中含有相同的html文件，则会按顺序进行渲染

# models.py

from django.db import models

# Create your models here.


class Student(models.Model):
    SEX_ITEMS = {
        (1, '男'),
        (2, '女'),
        (0, '未知'),
    }

    STATUS_ITEMS = {
        (0, '申请'),
        (1, '通过'),
        (2, '拒绝'),
    }

    name = models.CharField(max_length=128, verbose_name='姓名')
    sex = models.IntegerField(choices=SEX_ITEMS, verbose_name='性别')
    profession = models.CharField(max_length=128, verbose_name='职业')
    email = models.EmailField(verbose_name='邮箱')
    qq = models.CharField(max_length=128, verbose_name='QQ')
    phone = models.CharField(max_length=128, verbose_name='电话')

    status = models.IntegerField(choices=STATUS_ITEMS, default=0, verbose_name='审核状态')

    create_time = models.DateTimeField(auto_now=True, editable=False, verbose_name='创建时间')

    def __str__(self):
        return '<Student: {}>'.format(self.name)

    class Meta:
        verbose_name = verbose_name_plural = '学员信息'

# admin.py

from django.contrib import admin
from .models import Student

# Register your models here.

class StudentAdmin(admin.ModelAdmin):
    list_display = ('id', 'name', 'sex', 'profession', 'email', 'qq', 'phone', 'status', 'create_time')
    list_filter = ('sex', 'status', 'create_time')
    search_fields = ('name', 'profession')

    fieldsets = (
        (None, {
            'fields': (
                'name',
                ('sex', 'profession'),
                ('email', 'qq', 'phone'),
                'status'
            )
        }),
    )


admin.site.register(Student, StudentAdmin)

# views.py

from django.shortcuts import render
from .models import Student

# Create your views here.


def index(request):
    students = Student.objects.all()
    return render(request, 'index.html', {'students': students})

在admin，如果数据库表中的字段含有choice参数，Django会自动条用get_status_display方法，所以不用配置

在前端页面中，如果要调用含有choice参数的对象，则要调用get_Field_display方法

{# index.html  #}

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h1>学院列表</h1>
    {% for student in students %}
        <li>{{ student.name }} - {{ student.get_status_display }}</li>
    {% endfor %}
</body>
</html>
