playframework-2.0

问题 this is the route to handle the login POST request: POST /login/submit controllers.Users.loginSubmit(user : String, password : String) this is the login.scala.html: <form method="post" action="???"> <input type="text" name="username" /><br/> <input type="password" name="password" /><br/> <input type="submit" value="Login" /> </form> I got two questions: what should be the value of action? is it "login/submit"? how do you pass this form to be handled in the loginSubmit function? thanks 回答1: If

问题 I am using the playframework 2.0 with scala and I am facing many problem with the @select template. So what I have is a @select field as part of a Form (the Form shouldn't be interesting here): @select( Form("<variable of select 1>"), options = options(<call of function which returns a list>), '_default -> "--- stupid select templates ---", '_error -> Form.globalError ) now i have another select. Important about this one is - I want to fill it from a function, which gets the actual value of

问题 I have a Play project running on Play 2.1.1 . I would like to define a separate and distinct task to jar up only a specific package in my Play project (e.g. just the models package). I do not wish to override the current package tasks as I want to preserve their behaviour. How would I go about creating a custom task based off of the current package task? I've looked at Custom Settings and Tasks in the SBT documentation but these examples are fairly trivial and don't give any examples that use

问题 I'm trying to read a JSON that could have the following parameters coming from the client { "email" : "foobar@gmail.com", "password" : "XXXX", "facebookToken": "XXXXXXXXXXX" } The facebookToken could be Null or Not present, in which case the Email/Password should be filled, and vice versa. I'm having trouble constructing this Reader, here's what I have so far: val loginEmail = ( ( __ \ "email").read[String] and ( __ \ "password").read[String] )((email: String, password: String) => new User

问题 I am accessing SSL secured pages from play app. When the certificate of the page can't be trusted (because it has expired or is self signed or whatever other reason it might be) I would like to extract this information from my call and do some action accordingly. When I access such a page in the browser, it warns me that there is something wrong with the certificate. When I write something like this in play (the https page here has a bad certificate): package controllers import play.api.mvc.

问题 I have the following classes: import play.db.ebean.Model; import javax.persistence.*; @Entity public class A extends Model { @Id private int id; /* Other irrelevant properties */ @OneToOne(cascade = CascadeType.ALL, optional = true) private B b; } import play.db.ebean.Model; import javax.persistence.*; @Entity public class B extends Model { @Id private int id; /* Other irrelevant properties */ @OneToOne(mappedBy = "b") private A a; @OneToOne(cascade = CascadeType.ALL, optional = false)

问题 I need to generate/export a excel file from a table that is generated from a list of objects. I can see that there is a module for Play 1.x but not for Play 2.x and. I found a possible solution but it is written in scala (I think) here: http://aishwaryasinghal.wordpress.com/2012/05/17/generating-excel-in-play-2/ I've tried to implement this but I think my imports doesn't work. import java.io.FileOutputStream; import org.apache.poi.xssf.usermodel.*; import org.apache.poi.xssf.*; import org

问题 Newbie to Heroku here. I've gone through the motions described here: http://www.playframework.org/documentation/2.0.2/ScalaTodoList And I've managed to set up a simple Play app on Heroku. Next up, I've tried uploading my main application which I've been developing on my own station, by going through the same steps as earlier. Uploading and compilation worked, however the app keeps crashing with code 255. Here is are the logs: 2012-08-21T19:07:29+00:00 heroku[slugc]: Slug compilation started

问题 I had to configure the language_in option in the closure compiler to ECMASCRIPT5 to compile the libs Ember, Angular and others it's require ES5... There must be a better way, but I implemented this way: // Build.scala val root = new java.io.File(".") val defaultOptions = new CompilerOptions() defaultOptions.closurePass = true defaultOptions.setProcessCommonJSModules(true) defaultOptions.setCommonJSModulePathPrefix(root.getCanonicalPath + "/app/assets/javascripts/") defaultOptions
