strip_tag开发者_如何学Cs works for me in my view page, but not in my model (i'm using it in a before_save function)
You can also access helpers in your models like this:
ActionController::Base.helpers.strip_tags(text)
ActionView::Base.full_sanitizer.sanitize(your_html_string)
This will work for you. Or you can define a helper like:
def strip_html_tags(string)
ActionView::Base.full_sanitizer.sanitize(string)
end
And then use this like:
strip_html_tags(your_html_string)
To remove some specific tags pass additional parameters. Source: Sanitize Rails API Dock
So, I didn't like any of these solutions as i'd rather keep view functionality out of my models. So instead I used a decorator (like https://github.com/drapergem/draper) and was then able to use the helper method short cut h.strip_tags
.
The poor man's truncator:
my_string[0, 145]
It will work in a model without having to call helper methods from ActionController::Base. It won't add the elipsis for you, but that's probably easy to fix...
strip_tags
is a helper method and helpers aren't available inside models as a rule.
You might want to look at using something like the sanitize gem instead
