问题 In a Lift application, I’d like to add a special tag which takes the <tbody> part of the next table and adds odd and even classes (for example) to each <tr> tag. Alternating, of course. While I have found a way to add another attribute to all <tr> tags, there are still a few problems left (see code below). First, it doesn’t work. cycle.next is called too often, so in the end, everything is an odd row. Other problems are that the code doesn’t exclude inner tables (so a nested <tr> would be

问题 I'm not very familiar with lift framework and wanted to know if the following use case is possible using lift framework. On server1, Lift is serving REST webservice at following url "/contact/" However, if the client sends request to the following URL https://server1/contact/meet/" then it is not implemented on this specific server but "might" be implemented by another server. Can Lift redirect any such unsupported URLs to some specific server? Eg, in 302 response, can Location be specified

问题 For some reason sbt bails on .11.3 when working with the mongodb-record auth project, and it seems to me that's the only version i can download from the git site. 回答1: The idiomatic way is to specify sbt version in build.properties as sbt.version=0.11.2 But since group id in 0.11.3 was changed from org.scala-tools.sbt to org.scala-sbt , sbt can't resolve older versions. But you still can manually download older version of launcher from typesafe repo. 来源： https://stackoverflow.com/questions

问题 I have a JSON file containing quite a lot of test data, which I want to parse and push through an algorithm I'm testing. It's about 30MB in size, with a list of 60,000 or so elements. I initially tried the simple parser in scala.util.parsing.json, like so: import scala.util.parsing.json.JSON val data = JSON.parseFull(Source.fromFile(path) mkString) Where path is just a string containing the path the big JSON file. That chugged away for about 45 minutes, then threw this: java.lang

问题 I am try to write inside html document. this is my javascript code: <script type="text/javascript">document.write("Hello World!")</script> I am working with chrome and get the following error: Uncaught TypeError: Object # has no method 'write' I tried alert method and it worked. EDIT: this is part of a project in scala/lift that also uses jquery if that may hint something. I suspect document object is redefined. is there a way to know that / to access the original one? 回答1: I had a similar

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . I'm currently developing a web application using PHP, but I'm considering developing the web application using the lift framework instead, because twitter and foursquare have implemented it. I know a few benefits using lift/Scala but, could you guys mention some benefits

问题 Is there a way to make this work (Scala 2.8.1): class A class B def f(implicit b: B) {} implicit val a = new A implicit def aToB(a: A) = new B f(a) // works ok f // error: could not find implicit value for parameter b: B Actually my problem is with Lift's (2.2) dependency injection, i'm trying to convert Vendor[T] to T and implicitly require it in a class constructor without adding imports after each val: object DependencyFactory extends Factory { implicit def vendorToVal[T](vendor: Vendor[T]

问题 Hoping for some guidance. Consider this snippet: val q = (for { (d, o) <- dx innerJoin ox on (_.user === _.id) } yield(d,o)) "div" #> q.map { case (x, y) => { ".dF1 *" #> x.name & ".dF2 *" #> y.id } } in this query, I have two tables, where table "ox" is a list of people, and "dx" is a list of items associated with those people. As it is written, it works good, but I end up creating one row for each item that a person has. So assume three users, first two have two items, and last one has 1, i

问题 I have an external java project that my lift project depends on. I have been able to add the dependency to the classes in that project by adding the following line to my sbt: unmanagedClasspath in Compile += file("[Path to My Project]/classes") But this project also has a lib folder with a set of jars that it references and I cannot figure out what the correct syntax should be to add these dependencies. Have tried the following but it does not work: unmanagedJars in Compile += file("[Path to
