error trying to migrate in postgres

[ashton]

I'm trying to make a migration in postgres, I'm following the getting started and using the integreation with leiningen:

{:aliases {"migrate"  ["run" "-m" "investtrack.scripts.migration/migrate"]
            "rollback" ["run" "-m" "investtrack.scripts.migration/rollback"]}}

(ns investtrack.scripts.migration
  (:require [ragtime.jdbc :as jdbc]
            [ragtime.repl :as repl]))

(defn load-config []
  {:datastore  (jdbc/sql-database "jdbc:postgresql://postgres@localhost/investtrack")
   :migrations (jdbc/load-resources "migrations")})

(defn migrate []
  (repl/migrate (load-config)))

(defn rollback []
  (repl/rollback (load-config)))

Runing the command: $ lein migrate I get the following error:

Try changing your load-config function to:

(defn load-config []
  {:datastore  (jdbc/sql-database {:connection-uri "jdbc:postgresql://postgres@localhost/investtrack"})
   :migrations (jdbc/load-resources "migrations")})

[ashton]

changed to:

(defn load-config []
  {:datastore  (jdbc/sql-database {:connection-uri "jdbc:postgresql://localhost/investtrack?user=postgres"})
   :migrations (jdbc/load-resources "migrations")})

because the URI with user@host wasn't working, but I got the same error:

Could you run lein deps :tree on your repository? Perhaps there's a dependency issue.

If there's no problems with the dependencies, can you create a small project that replicates this error?

[ashton]

Here is the dependency tree:

Possibly confusing dependencies found:
[korma "0.4.0"] -> [org.clojure/java.jdbc "0.3.5"]
 overrides
[ragtime "0.7.2"] -> [ragtime/jdbc "0.7.2"] -> [org.clojure/java.jdbc "0.5.8"]

Consider using these exclusions:

[weavejester]

There's a dependency warning:

Possibly confusing dependencies found:
[korma "0.4.0"] -> [org.clojure/java.jdbc "0.3.5"]
 overrides
[ragtime "0.7.2"] -> [ragtime/jdbc "0.7.2"] -> [org.clojure/java.jdbc "0.5.8"]

Korma is forcing an older version of java.jdbc to be used. Try adding in an explicit dependency to your project file:

[org.clojure/java.jdbc "0.5.8"]

I'm also getting an error when trying to migrate with Postgres but the issue is different from Ashton's.

The error I'm getting with running lein migrate is:

My integration with Leiningen is also similar to Ashton's but my project.clj is:

   [ragtime "0.8.0"]

@albertchan I was having the same issue, changing [postgresql "9.3-1102.jdbc41"] for [org.postgresql/postgresql "42.2.5"] dependency solved that.
