1.models.py設定

from django.db import models
from django.contrib.auth.models import User
from django.contrib.auth.models import AbstractUser

class NewUser(AbstractUser):
profile = models.CharField('profile', default='', max_length=256)

    def __str__(self):
return self.username

class 
 
Column(models.Model):
name = models.CharField('column_name', max_length=256)
    intro = models.TextField('introduction', default='')

    def __str__(self):
return self.name

    class Meta:
verbose_name = 'column'
verbose_name_plural = 'column'
ordering = ['name']


class ArticleManager(models.Manager):
 
def query_by_column(self, column_id):
query = self.get_queryset().filter(column_id=column_id)

    def query_by_user(self, user_id):
user = User.objects.get(id=user_id)
        article_list = user.article_set.all()
        return article_list

    def query_by_polls(self):
query = self.get_queryset().order_by('poll_num'
 
)
        return query

    def query_by_time(self):
query = self.get_queryset().order_by('-pub_date')
        return query

    def query_by_keyword(self, keyword):
query = self.get_queryset().filter(title__contains=keyword)
        return query


class Article(models.Model):
objectes = ArticleManager()
    column = models.ForeignKey(Column, blank=True, null=True, verbose_name='belong to')
    title = models.CharField(max_length=256)
    author = models.ForeignKey(NewUser)
    image = models.ImageField(upload_to='img')
    content = models.TextField('content')
    pub_date = models.DateTimeField(auto_now_add=True, editable=True)
    update_time = models.DateTimeField(auto_now=True, null=True)
    published = models.BooleanField('notDraft', default=True)
    poll_num = models.IntegerField(default=0)
    comment_num = models.IntegerField(default=0)
    keep_num = models.IntegerField(default=0)

    def __str__(self):
return self.title

    class Meta:
verbose_name = 'article'
verbose_name_plural = 'article'
@property
def image_url(self):
if self.image and hasattr(self.image, 'url'):
return self.image.url

src="{{ article.image_url|default_if_none:'#' }}"

class Comment(models.Model):
user = models.ForeignKey(NewUser, null=True)
    article = models.ForeignKey(Article, null=True)
    content = models.TextField()
    pub_date = models.DateTimeField(auto_now_add=True, editable=True)
    poll_num = models.IntegerField(default=0)
    def __str__(self):
return self.content


class Poll(models.Model):
user = models.ForeignKey(NewUser, null=True)
    article = models.ForeignKey(Article, null=True)
    comment = models.ForeignKey(Comment, null=True)

2.admin.py設定（設定在後臺的顯示）

from django.contrib import admin
from django.db import models
from django import forms
from .models import Comment, Article, Column, NewUser

class CommentAdmin(admin.ModelAdmin):
list_display = ('user_id','article_id','pub_date', 'content','poll_num')

class ArticleAdmin(admin.ModelAdmin):
formfield_overrides = {
        models.TextField: {'widget': forms.Textarea(
                           attrs={'rows': 41,
'cols': 100
})},
}
    list_display = ('title','pub_date', 'poll_num')

class NewUserAdmin(admin.ModelAdmin):
list_display = ('username','date_joined', 'profile')

class ColumnAdmin(admin.ModelAdmin):
list_display = ('name', 'intro')


admin.site.register(Comment, CommentAdmin)
admin.site.register(Article, ArticleAdmin)
admin.site.register(Column, ColumnAdmin)
admin.site.register(NewUser, NewUserAdmin)

3.forms.py設定

主要設計了評論和上傳的表單

from django import forms
from django.forms import ModelForm
from .models import Article

class CommentForm(forms.Form):
comment = forms.CharField(label='', widget=forms.Textarea(attrs={'cols': '60', 'rows':'6'} ))


class PostForm(ModelForm):
class Meta:
model = Article
        fields = '__all__'

<form action="/image/{{ article.id }}/comment/" method="post">
    {% csrf_token %}
    {{ commentform.as_p }}
    <input class="btn btn-default" type="submit" value="Submit" />
</form>
