Play framework template automatically imports models._ among other things

由 北战南征 提交于 2019-12-21 02:51:32
问题 It seems like in Play framework templates, there is an implicit "@import models._" and "@import play.api.data.Form" because my code: @(title: String)(myForm: Form[User]) <!DOCTYPE html> <html> .... </html> works without having to put explicit import statements after the first line. This issue has been raised in the past: https://groups.google.com/d/msg/play-framework/7FT68jd5asU/xYF0VNySJYcJ What other classes/objects are implicitly imported? 回答1: You're right, Play Framework automatically

Less Verbose way of generating Play 2's javascript router

由 妖精的绣舞 提交于 2019-12-20 12:32:35
问题 Currently I define my app's javascript router in a fairly verbose way def javascriptRoutes = Action { implicit request => import routes.javascript._ Ok(Routes.javascriptRouter("jsRoutes")( Login.method1,Login.Method2, OtherController.method1,OtherController.method2, //[...] )).as("text/javascript") } What I really would like to do is to create a javascriptRouter with all of the routes in the routes file, so I don't have to manually update the javascriptRoutes definition each time I add a new

How to pass raw html to Play framework view?

由 痴心易碎 提交于 2019-12-20 10:25:33
问题 I'm trying to pass a simple URL to a view within a play framework app, however when passed as a string, the & in the url is changed to & which causes the URL to not work. If I change the argument to Html, i.e @(url: Srting) to @(url: Html) , then I get an error when I try to pass the url as string to view.render() method. How can I convert the url into Html and pass it as that? 回答1: To prevent the default escaping that happens for dynamic content on views you need to wrap the String with

Using Eclipse with Play Framework 2.0

由 扶醉桌前 提交于 2019-12-20 09:23:52

A similar question: Debug Playframework 2.0 in Eclipse The answer to that question did not have specific enough instructions for me to know how to follow. 回答1: Question 1: After you have eclipsified,

Play! framework - database issue with Evolutions

由 烂漫一生 提交于 2019-12-20 09:20:00
问题 I'm using Play! framework 2.0 and I'm stuck on an annoying issue involving the database. Suppose I have a User (extends Model ) class which has few attributes ( first_name , last_name , email , password etc). At some point I want to add a new attribute, lets say last_ip (it doesn't really matter what it is). So, I add the attribute to the User class, compile and run. The thing is: I get this red alert about database changes (obviously) which asks me to press "APPLY CHANGES" (if I remember

Get rid of Scala Future nesting

由 天涯浪子 提交于 2019-12-20 08:30:00
问题 Again and again I am struggling when a function relies on some future results. This usually boils down to a result like Future[Seq[Future[MyObject]]] To get rid of that I now use Await inside a helper function to get a non-future object out and reduce the nesting. It looks like this def findAll(page: Int, perPage: Int): Future[Seq[Idea]] = { val ideas: Future[Seq[Idea]] = collection.find(Json.obj()) // [...] ideas.map(_.map { // UGLY? idea => { // THIS RETURNED A Future[JsObject] before val
