Well first I will say that I am a little bit upset with Ember lack of documentation (or up-to-date information) and clear explanations (an advice to people who write documentations : people who read it do not have the same knowledge as you).
Since you’re using :profil_id, to what model are You linking here? Use…
{{#linkTo 'profil' this}}{{name}}{{/linkTo}}
Edit:
I would advise You to use full emberjs, instead of min. version. Difference between debug messages is obvious:
Uncaught TypeError: Cannot read property ‘__ember1376604573025_meta’ of undefined
vs
Assertion failed: Cannot call get with ‘id’ on an undefined object.
Sorry, I still don’t understand why. I expected profil_id to link to an App.Profil object. Apparently documentation was updated and gives an example that is different from what I had first. Well, ok I should have give a look since
I already use full emberjs and I don’t know why my object is undefined without this.
