class ArticlePost(models.Model):
author = models.ForeignKey(User, on_delete=models.CASCADE)
title = models.CharField(max_length=200)
slug = models.SlugField(max_length=500)
column = models.ForeignKey(ArticleColumn, related_name="article_column", on_delete=models.CASCADE)
body = models.TextField()
created = models.DateTimeField(default=timezone.now())
updated = models.DateTimeField(auto_now=True)
class Meta:
ordering = ("title",)
index_together = (("id", "slug"),) #对id,slug字段建立索引
def __str__(self):
return self.title
def save(self, *args, **kargs): #重写save
self.slug = slugify(self.title) #实现slug
super(ArticlePost, self).save(*args, **kargs)
def get_absolute_url(self):
return reverse("article:article_detail", args=[self.id, self.slug]) #获取某篇文章的url
在article/forms.py中创建表单
class ArticlePostForm(forms.ModelForm):
class Meta:
model = ArticlePost
fields = ("title", "body")

@login_required(login_url="/account/login")
@csrf_exempt
def article_post(request):
if request.method == "POST":
article_post_form = ArticlePostForm(data=request.POST)
if article_post_form.is_valid():
cd = article_post_form.cleaned_data
try:
new_article = article_post_form.save(commit=False)
new_article.author = request.user
new_article.column = request.user.article_column.get(id=request.POST["column_id"])
new_article.save()
return HttpResponse("1")
except:
return HttpResponse("2")
else:
return HttpResponse("3")
else:
article_post_form = ArticlePostForm()
article_columns = request.user.article_column.all() #通过创建ArticleColumn建立的外键参数related_name='article_column'查找对应数据
return render(request, "article/article_post.html", {"article_post_form": article_post_form, "article_columns": article_columns})
在article/urls.py中设置url
