ping了好几次，都是这个IP

应该是这样：HttpResponse是类，http是包，django是模块

@AbosFreeman 加油加油：）

貌似现在很多不能打开的情况，上海这边是可以打开的

我大概知道怎么做就行了，不用死记。很多api真想用时，查一下具体用法 就行啦

在__init__.py里 写的东西 在整个package里共享 的

@george.guo.chen 应该没有吧，上海这边打开正常

form没有和model绑定，你可以自己设置任何字段进行处理，ModelForm则是和model绑定的，例如你的表单是生成 一篇文章，那么这个form和文章 model绑定就可以了。 一般来说，使用比较多的是 ModelForm

Forms created from forms.Form are manually configured by you. You're better off using these for forms that do not directly interact with models. For example a contact form, or a newsletter subscription form, where you might not necessarily be interacting with the database.

Where as a form created from forms.ModelForm will be automatically created and then can later be tweaked by you. The best examples really are from the superb documentation provided on the Django website.

forms.Form:

Documentation: Form objects Example of a normal form created with forms.Form:

from django import forms

class ContactForm(forms.Form):
    subject = forms.CharField(max_length=100)
    message = forms.CharField()
    sender = forms.EmailField()
    cc_myself = forms.BooleanField(required=False)

forms.ModelForm:

Documentation: Creating forms from models Straight from the docs:

If your form is going to be used to directly add or edit a Django model, you can use a ModelForm to avoid duplicating your model description.

Example of a model form created with forms.Modelform:

from django.forms import ModelForm

# Create the form class.
class ArticleForm(ModelForm):
    class Meta:
        model = Article

This form automatically has all the same field types as the Article model it was created from.

@haixe 是啊

顶~

是不是 语言文件 没编译好？

@xxer 什么问题？

@xxer 把目录删除掉，重新安装下试试

@huangturen2007 嗯，记下 了：）

scripts下面 没有django-admin.py 你是如何 运行命令的。。。肯定会报错啊

你需要给更多一点的信息，

外键的使用，例如：

employee = Employee(first_name="Name", last_name="Name")
employee.type_id = 4
employee.save()

http://stackoverflow.com/questions/2846029/django-set-foreign-key-using-integer

在你的例子里，就是先生成 一个img对象，得到id,然后设置在data对象里就行了

@greenpointan 嗯嗯，回头整个。 嗯嗯，国内的域名比较坑爹。 本社区就部署在东京，哈哈。。

赞啊。我是不是应该写个页面 来推荐优秀的开源django项目？

另外，域名怎么没有申请一个？

使用 file.name

class PDFUpload(models.Model):
    user = models.ForeignKey(User, editable=False)
    desc = models.CharField(max_length=255)
    file = models.FileField(upload_to=upload_pdf)

{% for download in downloads %}
    <div class="download">
        <div class="title">{{download.file.name}}</div>
        <div class="size">{{download.file.size}} bytes</div>
        <div class="desc">{{download.desc}}</div>
    </div>
{% endfor %}

编辑器问题给你私信了哈

"all": ("my_styles.css",)

https://docs.djangoproject.com/en/1.7/topics/forms/media/#form-asset-paths

CSS文件和JS文件的路径不对，你试着修改一下看看

@From_scratch_2012 赞哈

@shanyuze1029 当然可以啊

重新 启动一下？

You can't rely on it, but you can try the request.META['REMOTE_HOST'] or request.META['HTTP_HOST'] from the META dictionary of the request :

A standard Python dictionary containing all available HTTP headers. Available headers depend on the client and server, but here are some examples:

- REMOTE_HOST -- The hostname of the client.
- HTTP_HOST -- The HTTP Host header sent by the client.

@shanyuze1029 windows下没玩过啊。。windows不靠谱的

@alexkh 都是自己写的python脚本啦，然后用crontab定时就好了。我的任务都比较简单，没用框架。
