Are truncate and raw mutually exclusive methods in ruby?

I am trying to do this truncate raw(@some_text), length: 300 . When the text exceeds the limit of 300 characters I see html tags in the text.

I need to truncate and implement html(tags prepended and appended) properties in the text. Is there any other way to do the same? Thanks in Advance.

Here's code we use for this:

#app/helpers/application_helper.rb
def clean(content, length)
    body = sanitize(content, tags: [])
    truncate(body, length: length, separator: " ")
end

If you put that into a helper, you can call: clean(@some_text, "300")

This should work raw(@some_text.slice(0,300))

Try this to both truncate and remove html tags from the text....

truncate(strip_tags(@some_text), :length => 300)

Your problem is by truncating you'll be removing the closing tags. You're basically going to need to strip all the tags if you need to truncate it.
