pow很棒,但是我的应用程序中的很多东西都假设是https,通过它们并添加"if not dev environment"会很痛苦.是否可以让pow服务https？
我曾经这样做过:
Foo.find_by_bar('a-value')
我现在可以这样做:
Foo.where(:bar => 'a-value').limit(1).first
这是推荐的吗？这是最好的方法吗？我应该继续使用"旧的"方式,因为它仍然是有用的语法糖,或者是否有更好的方式我现在可以做到这一点,这将支持链接和所有其他好东西？
当HTTP状态代码为302时,如何使用cURL获取目标URL？
<?PHP
$url = "http://www.ecs.soton.ac.uk/news/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$html = curl_exec($ch);
$status_code = curl_getinfo($ch,CURLINFO_HTTP_CODE);
if($status_code=302 or $status_code=301){
$url = "";
// I want to to get the destination url
}
curl_close($ch);
?>
我正在尝试检查我的RESTful控制器中的新操作是否设置了所需Object类型的实例变量.看起来非常典型,但执行它时遇到了麻烦
客户控制器
def new
@client = Client.new
end
测试
describe "GET 'new'" do
it "should be successful" do
get 'new'
response.should be_success
end
it "should create a new client" do
get 'new'
assigns(:client).should == Client.new
end
end
结果是...
'ClientsController GET 'new' should create a new client' FAILED
expected: #,
got: # (using ==)
这可能是因为它试图比较两个不同的活动记录实例.那么,我如何检查控制器是否设置了一个包含Client模型新实例的实例变量.
如果您已将对象上传到Amazon S3存储桶,那么如何使用API更改元数据？可以在AWS管理控制台中执行此操作,但不清楚如何以编程方式完成此操作.具体来说,我在Python中使用boto API并且从阅读源代码可以清楚地看出,使用key.set_metadata只能在创建对象之前工作,因为它只会影响本地字典.
我正在尝试使用DelayedJob并且作业失败,在数据库中出现以下错误:

有什么建议怎么处理吗？
在Rails控制器中,我可以像这样设置一个cookie:
cookies[:foo] = "bar"
并指定"安全"(https-only)标志如下:
cookies[:foo, :secure => true] = "bar"
:secure默认为false.如何在应用程序范围内默认使用cookie？
这是在Rails 2.3.8上
我在我的模型中使用此正则表达式来验证用户提交的URL.我不想强迫用户输入http部分,但是如果它不在那里,我想自己添加它.
validates :url, :format => { :with => /^((http|https):\/\/)?[a-z0-9]+([-.]{1}[a-z0-9]+).[a-z]{2,5}(:[0-9]{1,5})?(\/.)?$/ix, :message => " is not valid" }
知道我怎么能这样做吗？我对验证和正则表达式的经验很少..
当我说布局时我并不仅仅意味着视图,我生成那些.在我自己的邮件上,我正在使用默认布局.我在SomeMailer.rb文件中定义
#some_mailer.rb
class SomeMailer < ActionMailer::Base
layout 'sometemplate'
我是否可以通过某种方式为Devise Mailer等人做到这一点？
