How can I allow <source> tags through rails 4 sanitize?

由 自闭症网瘾萝莉.ら 提交于 2020-01-15 03:41:07
问题 I've been using the sanitize method in a Rails 4 app to scrub a page which displays html that users generate to prevent unsafe things like script injection. So I have a view that looks like: sanitize @user_input Right now I'm having issues when uses are entering video tags with a source tag under it like so: <video><source src="foo.bar"></video> Unfortunately it looks like sanitize is stripping out the source tag so videos are no longer working. How do I use sanitize so it allows source tags?

问题 I am looking to use ActionView::Helpers::NumberHelper from a Ruby script. What all do I need to require etc.? 回答1: ~> irb ruby-1.9.2-p180 :001 > require 'action_view' => true ruby-1.9.2-p180 :002 > ActionView::Base.new.number_to_currency 43 => "$43.00" 回答2: As of Rails 3.2.13, you can do the following: class MyClass include ActionView::Helpers::NumberHelper def my_method ... number_with_precision(number, precision: 2) ... end end You might need to require 'action_view' too.

问题 I want to render dropdown list in form with images as options. How to achieve this in rails3? 回答1: I like the msdropdown.

Rails form_tag form writing - with non-active record model

由 ♀尐吖头ヾ 提交于 2019-12-08 16:29:35
问题 I'm somewhat of a Rails newbie. I'm writing a couchrest-rails app, so am not using activerecord for this model. I just figured out that that means that form_for(@model) won't work. I'm trying to work out how to use form_tag -- but most of the examples don't involve new & create actions. This is wrong: <h1>New article</h1> <% form_tag new_article_url(@article), :method => :post do |f| %> <%= f.error_messages %> <p> <%= f.label :title %><br /> <%= f.text_field :title %> </p> <p> <%= f.submit
