我似乎为我的用户身份验证设置了Devise,并设置了:确认选项.

当我在浏览器中运行它时,一切似乎运行良好,我注册,转到我的rails s控制台中的服务器日志中显示的确认URL .

但是,当我尝试将以下内容添加到我的db/seed.rb时

User.create!(:username => 'haar', :email => 'haar@example.com', :password => 'password', :password_confirmation => 'password')

并运行 rake db:setup --trace

我收到以下错误:

我使用ZSH作为我的终端shell,虽然我已经编写了几个函数来自动执行特定任务,但我从来没有尝试过任何需要我目前所需功能的东西.

我最近使用Jekyll重新编写了一个博客,我希望自动生成博客文章,最后使用像scp这样的东西将新生成的文件上传到我的服务器.

我对ZSH中的变量绑定/用法略感困惑; 例如:

DATE= date +'20%y-%m-%d'
echo $DATE

按照我的预期正确输出2011-08-23.

但是当我尝试:

DATE= date +'20%y-%m-%d'
FILE= "~/path/to/_posts/$DATE-$1.markdown"
echo $FILE

它输出:

2011-08-23
blog.sh: line 4: ~/path/to/_posts/-.markdown: No such file or directory

当运行我想要的博客标题时(忽略字符串需要被操纵以使其更友好的URL并且路径路径/不存在的事实)

即博客"博客标题",输出:

2011-08-23
blog.sh: line 4: ~/path/to/_posts/-blog title.markdown: No such file or directory

为什么在打印$ FILE的调用之上打印$ DATE而不是$ FILE中包含的字符串？

我有一个rails应用程序,最初使用Paperclip进行文件上传,但是,当我看到CarrierWave显然在表格重新显示时有一个"持久上传"类型功能时,我决定尝试一下.

在我看来,我有以下几点:

= f.input :attachment
= f.hidden_field :attachment_cache

如果表单验证失败并重新显示,则正确缓存文件,但是当我更正验证错误并重新提交时,不会处理附件.

我最近加入了一个项目，每个客户都有自己的自定义 HTML 内容，用于发送给其客户的电子邮件。

它通过将内容插入带有自定义标签的字符串中来实现此目的，然后通过在邮件程序中设置 body 属性来发送，如下所示：

mail(:from         => from_email,
     :reply_to     => from_email,
     :to           => to_email,
     :subject      => subject,
     :body         => (html_text.empty?) ? plain_text : html_text,
     :content_type => (html_text.empty?) ? 'text/plain' : 'text/html',
    )

要添加的一项功能是包含内嵌图像；但是 - 通过手动将 content_type 设置为“text/plain”或“text/html”，电子邮件无法正确呈现，并且图像也无法正确附加（整个电子邮件的 content_type 似乎很混乱）： 。

删除此显式 content_type 后，图像会正确附加，但不会显示内联图像（使用附加图像将占位符替换为 image_tag），因为内容似乎不会被解释为 HTML，例如电子邮件的内容是：

Dolor eligendi doloremque et.
<img alt="Signature Image" src="cid:5225b25b53818_b4213fc5ce0349d0975f@localhost.mail" />

如何让电子邮件将内容正确解释为 HTML，而不弄乱内嵌图像内容类型？
