ProvisionException: Unable to provision - scala

Question

I got this error while trying to integrate postgresql into my play app:
ProvisionException: Unable to provision, see the following errors:
1) No implementation for play.api.db.slick.DatabaseConfigProvider was bound.
while locating play.api.db.slick.DatabaseConfigProvider

My application.conf
slicks.dbs.default.driver="slick.driver.PostgresDriver$"
slicks.dbs.default.dataSourceClass="slick.jdbc.DatabaseUrlDataSource"
slicks.dbs.default.db.default.driver = org.postgresql.Driver
slicks.dbs.default.db.default.url = "jdbc:postgresql://localhost:5000/aleksander"
slicks.dbs.default.db.default.user = postgres
slicks.dbs.default.db.default.password = "lelelel"
The parts with the injection
class EntryRepo #Inject()(protected val dbConfigProvider: DatabaseConfigProvider) {...}
class Entries #Inject()(entryRepo: EntryRepo) extends Controller {...}
I've been following the play-slick3 template from activator. I tried to follow the template as close as possible but the error still persists

Answer 1

I had similiar issue and I was using Play 2.5.x.
In their new application.conf their code convention has changed from simple toggling to more "JSONish" formatting (called HOCON).
db {
foo
}
And you may be tricked into thinking that you should put
slicks.dbs.default.driver="slick.driver.PostgresDriver$"
slicks.dbs.default.dataSourceClass="slick.jdbc.DatabaseUrlDataSource"
slicks.dbs.default.db.default.driver = org.postgresql.Driver
slicks.dbs.default.db.default.url ="jdbc:postgresql://localhost:5000/aleksander"
slicks.dbs.default.db.default.user = postgres
slicks.dbs.default.db.default.password = "lelelel"
inside those db {} braces. However, after pulling my hairs for over 6 hours I found out that putting db configuration code OUTSIDE those braces solves my problem. You may have fallen into similiar trap.
Of course you can use this in jsonic fashion like this:
slicks.dbs.default.db { /* your slick configuration */}
