的帖子显示应该分页。。。

由于限制每个帖子内的评论回复不是很多，暂时不对评论进行分页。

直接允许会提示没有权限创建数据库。

I have error when compile with command mix ecto.create Repo

'cl.exe' is not recognized as an internal or external command, operable program or batch file. ERROR: compile failed while processing c:/Users/opami/Desktop/elixir-china/deps/bcrypt: rebar_abort ==> elixir_china ** (Mix) Could not compile dependency :bcrypt, "escript.exe "c:/Users/opami/.mix/rebar"" command failed. You can recompile this dependency with "mix deps.compile bcrypt", update it with "mix deps.update bcrypt" or clean it with "mix deps.clean bcrypt"
How to resolve this error? Thanks

每次都要登录，是我人品不行?

现在还没有统一的404 跟500错误的页面。

类似：

https://ruby-china.org/dsadsd

问题是换行在 Markdown 中默认是被转成空格的, 一般中文论坛都把换行开起来.

编辑器使用了 marked 但没有配置关于换行和 gfm 的选项.
这边引用的资源没有看到出处, 应该是在后边修改就可以的:
https://github.com/jw2013/elixir-china/blob/master/web/templates/layout/application.html.eex#L18

文档:
https://github.com/chjj/marked#usage

marked.setOptions({
  renderer: new marked.Renderer(),
  gfm: true,
  breaks: false,
});

这个PR 0e00ba1 merge后，编辑的时候我们也用Lepture editor了。。。

那东西更新的值没设置对，一直提交的是老的值。。。

这些错误信息目前包括注册时(http://localhost:4000/users):

用户名空白，用户名过短，邮箱空白，邮箱过短，用户名已存在，邮箱已存在。

因为这个是Ecto层的错误信息，我们需要想办法把他中文化。

注意因为登录(http://localhost:4000/signin)的错误信息是我们自己写的，就已经全部中文化了。

完成 @u2 的提议。

暂时我们只考虑现实显示Emoticon。

以后我们可以考虑用At.js来实现编辑的时候输入Emoticon字符能autocomplete和显示带emoticon的提示。

在http://elixir-cn.com/notifications里，添加一个按钮来标记所有的新消息已读。

:)

现在 navbar 挺空的，而且加个简单的页面作为 Wiki，可以引导大家去找到一些资料。以及一些实际的、**特色的问题，比如**的 Hex 源、如何找到一些线下组织（比如 Meetup、微信群、Slack 等信息）

比如“线下活动”，“OTP”，“Erlang”，“Phoenix”，“Hex”，甚至是其他的函数式语言或者并发能力强的语言等，具体可以再想想和讨论一下。

另外感觉 “学习资料” 有点宽泛，感觉现在大家更多是当“分享”在用

比如在主页有“jw2013 于 2015-1-6 15点23分 最后更新”，其实我们想说的是

“jw2013发的帖子 于 2015-1-6 15点23分 最后更新”

应该把所有项目里“xxx 于 2015-1-6 15点23分 最后更新”改为“xxx的帖子 于 2015-1-6 15点23分 最后更新”

不过库的选择有点多：

https://hex.pm/packages?search=oauth

有人有使用过其中某个的经验么？

发现用户名区分大小写。我觉得比较麻烦，登陆容易造成困扰，也容易冒认身份。

不然用户体验很差

0e00ba1

这次merge里的templates有bug导致了这个issue

和原来一样只给管理员显示删除按钮就好了

controller层还是对的 不用改

😭 😭 😭 😭 😭

有人在重写网站吗？

而不是帖子本身的发布时间。。。。

Bug由0abb363

造成

刚才登录论坛，提示用户名不存在，随后添上用户名之后说密码错误。
最后想重新注册提示说邮箱已经占用……
请问怎么解决？

0e00ba1

造成了这个bug

我希望是BSD/MIT

love your work!

i follow the install steps cause errors :

现在如果一个connection他的方法是DELETE，那么/pages/unauthorized会返回500 Internal Service Error.

ElixirChina.PageController 需要添加一个方法，效果是即使用户的请求是DELETE，也要执行

conn
    |> assign_layout(:none)
    |> render "unauthorized"

这个bug现在的表现直接体现在如果你想删除别人的帖子，虽然后端不让你删(是正确的)，但是返回的是500 Internal Service Error. 正确的做法是返回401错误的信息，或者直接redirect到401错误的网页。

美化https://github.com/jw2013/elixir-china/blob/master/web/templates/page/unauthorized.html.eex

不然把secret放在github上会被session hijack

首页被污染了啊

需要升级phoenix_html 版本，升级之后就是一片依赖的报警
【新手上路】所以暂时未解决该问题

现在的textarea只能文字

这也太烂一点了吧。。。。。。

elixir的logger目前只有内置console
需要配file log么
部署的时候 配下logrotate
