如何在Play Framework 2.3中从我的表单反向路由到操作

Question

Good day Everyone,

I am new to Play framework and am trying to get started building an application. Under the app/controllers folders i have created sub packages so i have something like app/controllers/products/ProductController.class .

In my routes.conf file i have added a sample route like this

GET /createproduct controllers.products.ProductController.listAllProducts() POST /createproduct controllers.products.ProductController.createProductDetail()

and i can goto the url http://localhost:9000/createproduct and see a sample view that i created.

My issue now is that i want to add a form to the view and when i try to use the form helper method to POST data to the POST URL above from my new view like this

@helper.form(action = routes.products.ProductController.createProductDetail()) {

i get the error that

value products is not a member of object controllers.routes

All the samples that i saw online only use the route.Application example which is doesnt fit my issue.

So my question is how do i reverse route to this action or route from a view using the Form helper

Answer 1

The valid syntax is:

[full-package-name].routes.[controller].[method]

So in your case it should be

 controllers.products.routes.ProductController.createProductDetail()

controllers.routes is imported implicity, therefore for using with controllers in default package you can short it to:

routes.Controller.action()
