Django学习笔记（三）

1. 列表显示数据模型的字段

---

polls/models.py

from django.db import models

from django.utils.encoding import python_2_unicode_compatible

@python_2_unicode_compatible       # only if you need to support Python 2

class Question(models.Model):

    # ...

    def__str__(self):

         return self.question_text

@python_2_unicode_compatible    # only if you need to support Python 2

class Choice(models.Model):

     # ...

     def__str__(self):

          return self.choice_text 

---

2. 显示多列数据

---

polls/admin.py

class QuestionAdmin(admin.ModelAdmin):

    # ...

    list_display=('question_text','pub_date')

---

3. 调整数据项的顺序

---

polls/admin.py

from django.contrib import admin

from.models import Question

classQuestionAdmin(admin.ModelAdmin):

    fields=['pub_date','question_text']

    admin.site.register(Question,QuestionAdmin)

---

4. 数据项分组（Group）

---

polls/admin.py

from django.contrib import admin

from .models import Question

class QuestionAdmin(admin.ModelAdmin):

    fieldsets=[

        (None,{'fields':['question_text']}),

        ('Date information',{'fields':['pub_date']}),

    ]

    admin.site.register(Question,QuestionAdmin)
