Django自定義表單

修改polls/admin.py

 from django.contrib import admin
from .models import Question, Choice


# Register your models here.


class ChoiceInline(admin.TabularInline):
model = Choice
extra = 3
# Choice對象要在Question後臺頁面編輯，默認提供3個足夠的選項字段


class QuestionAdmin(admin.ModelAdmin):
fieldsets = [
(None, {'fields': ['question_text']}),
('日期信息', {'fields': ['pub_date'], 'classes': ['collapse']}),
]

inlines = [ChoiceInline]

list_display = ('question_text', 'pub_date', 'was_published_recently')

list_filter = ['pub_date']

search_fields = ['question_text']


admin.site.register(Question, QuestionAdmin)
# 建立一個模型後臺類，接着將其做爲第二個參數傳給admin.site.register()

修改polls/models.py

import datetime
from django.utils import timezone
from django.db import models

# Create your models here.
# 在咱們的polls應用程序中，
# 將建立兩個模型：Question和Choice，
# Question有一個問題和一個出版日期,
# Choice有兩個領域：選擇的文本和票數，
# 每一個Choice都關聯一個Question


class Question(models.Model):
question_text = models.CharField(max_length=200, verbose_name='問題文本')
pub_date = models.DateTimeField('出版日期')

def __str__(self):
return self.question_text

class Meta:
verbose_name = '問題'
verbose_name_plural = '問題'

def was_published_recently(self):
now = timezone.now()
return now - datetime.timedelta(days=1) <= self.pub_date <= now

was_published_recently.admin_order_field = 'pub_date'
was_published_recently.boolean = True
was_published_recently.short_description = '最近發佈？'


class Choice(models.Model):
question = models.ForeignKey(Question, on_delete=models.CASCADE)
choice_text = models.CharField(max_length=200, verbose_name='選擇文本')
votes = models.IntegerField(default=0, verbose_name='選票')

def __str__(self):
return self.choice_text

class Meta:
verbose_name = '選擇'
verbose_name_plural = '選擇'
