Example for using tesla-mongo-connect

This is a very simple example for how to use mongo-db using the tesla-mongo-connect addon to tesla-microservice.

Running it

To start the application you can either use

• a mongo-db running on localhost (or whatever you change the config to in [default.properties](ls resources/default.properties)). Then you can start the application with lein run

• an embedded mongodb provided by embongo. Start the application with lein embongo run.

What is happening?

First some data is written into the collection testcol during starting up the system in example_system.clj:

(mongo/update-upserting! (:mongo started) "testcol" {:_id "myId"}
                             {:_id  "myId"
                              :foo  "bar"
                              :info "This was upserted into mongo in example-system.clj"})

The project contains a very simple page, which is dependent on :mongo in tesla-mongo-connect. If you call http://localhost:8080/example the data is read out of mongo and rendered into the html-response in page.clj:

(mongo/find-one-checked! (:mongo self) "testcol" {})
