Question

I have an object that I save like this in my controller:

@user = User.find(params[:id])

and when it comes time to display it, using HAML, I am trying to do something like this:

[e-mail]_name

but nothing gets rendered. What am I doing wrong? I saw many examples using the @user in a form. Should I do that even though I don’t have a form to create in this case? Or I also saw a lot of places that use the :some_var notation, but I am not certain which approach applies in this case.

Answer 1

Use equal sign instead of minus

= @user.first_name

Minus does not output anything to the HTML, it ignores returned value. Equal sign does emit returned value to the HTML.
