View helper is not html safe

[romaslmd]

Hi,
found this thing recently:

rails (4.2.1)
material_icons (2.0.1)
bootstrap-material-design (0.2.2)

(note: only on production env)
RAILS_ENV=production

# views/.../_action.html.slim
button.btn[type="submit"]
  = material_icon.search.md_18

output was a link with raw inner html as text

<button class="btn" type="submit"><i class="material-icons md-18 ">search</i></button>

but with

# views/.../_action.html.slim
button.btn[type="submit"]
    = material_icon.search.md_18.to_s.html_safe

all worked fine.

Hello @romaslmd,

When you use the helper, it returns an instance of MaterialIcon model. When to render it into the view, to_s method is called. This method uses content_tag, a helper provided by ActionView. Returned string of this method is html_safe, as you can see in ActionView::Helpers::TagHelper line 146.

The problem can come from Slim template engine, I will check it. Can you tell me the version of Slim?

Thanks!

slim (3.0.6)
slim-rails (3.0.1)

@Angelmmiguel
U r right, problem related to Slim.
probably best option is to use double equal sign in view:

== material_icon.search

Okey @romaslmd. I will close this issue and add a section in README. However, I will investigate it to report this if it's a Slim bug.

Thanks!
