amazon s3 - Rails AWS-SDK: Set Expiration Date for Objects -


in rails app, allow users upload images directly s3, creates temporary file gets automatically deleted after image record saved in database.

instead of automatically deleting image after record saved, i'd set expiration date file on s3 automatically gets deleted after period (say 24 hours).

i've seen documentation on how set expiration date on bucket (http://docs.aws.amazon.com/awsrubysdk/latest/aws/s3/bucketlifecycleconfiguration.html), want folder within bucket have files automatically removed.

does have suggestions how it?

s3 = aws::s3.new(:access_key_id => env['aws_access_key_id'], :secret_access_key => env['aws_access_key']) foldername = @image.s3_filepath.split("/")[5] folder_path = 'uploads/' + foldername s3.buckets[env['aws_bucket']].objects.with_prefix(folder_path).each( #set expiration date header here)

you set lifecycle configuration on bucket itself, not each individual object. using rest api you'd write out xml configuration (there's field prefix let's apply lifecycle config keys prefixed it) , put bucket.

converting on ruby sdk, looks example is doing want; first parameter of add_rule appears prefix.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
