问题 I have a particular set of views relating to one of my controllers, whereby I want any call to *_path or *_url to append a set of parameters. Is there some magic method I can override that will let me do this? I have no idea where in the Rails code the *_path or *_url methods are even handled. Edit for clarity: I'm looking for a way to do this such that I don't have to modify every link in every view where this needs to occur. I don't want every coder who touches this set of views to have to

问题 Is there a way to pass all ant command-line parameters as properties to a java task ? For example : ant -Dprop1=value1 -Dprop2=value2 ... -file build.xml myTarget <target name="myTarget"> <java classname="MyClass"> <sysproperty ... all properties> </java> </target> So the started jvm will have all properties passed from the ant command-line.

问题 I made an extensive search but I couldn't find any example about this. I have a .NET variable of type TimeSpan and I need to put it into an IntervalDayToSecond record of an Oracle DB.

问题 I have normal Scala class I am wanting to refactor to become an immutable case class. As I'm needing the class to be well-behaved in Set operations, I want all the Scala compiler automatically generated methods provided on a case class. IOW, I am wanting to avoid having to write these various methods; equals , hashCode , toString , etc., as that is very error prone. And I am needing to do this for a raft of classes, so I need a general solution, not just a specific solution anomalous quick

If there

问题 Eclipse has an option in Java Compiler tab: Store information about method parameters (usable via reflection) If I checked on the option. I am able to get method parameter via Parameter API.
