similar to: Want to use a view helper (TextHelper) in a model class

So I''ve googled my brains out, and I see a lot of talk about TextHelper for views, but next to no discussion about cleaning text _before_ it is saved. I figured this had to be asked 4 zillion times, but I''m not finding anything concrete/obvious. Using h is fine as a safety catch, but that alone is not acceptable to me as the means of diffusing the impact of HTML or JS

I am getting nil returned when doing the following: r.highlight(@condition, :field => ''body'') ''r'' is an instance of the a_a_f model. ''body'' is a tokenized saved field. I am running latest ferret and a_a_f trunk. Am I doing something wrong? -- Posted via http://www.ruby-forum.com/.

I tried to use a before_save and use simple_format, it returns and undefined method error. Can I even use these methods within a model? I tried to use auto_link and it failed too. What am I doing wrong? Furthermore, would it be recommended I format text before saving it to the database? Advantages or disadvantages? -- Posted via http://www.ruby-forum.com/.

Hi, This is more of a Ruby question than Rails. I want to autolink url''s in a given string. I''m not great with regular expressions and I wandered if anybody has an example. Thanks.

I''m having trouble succesfully getting access to the ActionView::Helpers::TextHelper.strip_tags method from one of my controllers. If I try to call it directly using ActionView::Helpers::TextHelper.strip_tags I get undefined method `strip_tags'' for ActionView::Helpers::TextHelper:Module What is the preferred way to make ActionView helpers available to a descendant of

I think there''s a logical mistake in ActionViews text_helper.rb. The TextHelper modul defines the methods textilize and textilize_without_paragraph in a begin rescue block that calls require_library_or_gem "redcloth". The problem is, that this call will always fail and the methods will never be defined when you install RedCloth as a plugin under vendor/plugins. That is

Hi I''ve contributed a patch which fixes an incorrect example in the documentation for auto_link in ActionView::Helpers::TextHelper. The example uses truncate in the old style of tuncate(text, length) which no longer works, so I''ve patched it to use the new tuncate(text, :length => n) style.

I''ve checked the Rails documentation but find no mention of link_to ''external url'' or equivalent. Does rails have a built in method to do this? thanks -Lindsay -- Posted via http://www.ruby-forum.com/.

Right now, I have the following in my application controller - and a simliar version is duplicated in test_helper. There must be a better way to include common functionality like this that gets used across layers? Maybe at the very least a way to include it at the class level and instance level with one line? # provide access to text helper at class level def self.text_helper

I''m using simple_format to format and display posted content from users. This content sometimes has urls in it. The problem I''m having is that if the urls are long enough to wrap, they do, but the url gets split with a <br> tag. Then, if the user clicks on the link, only the first, non-wrapped part of the link gets posted to the browser... and that''s an invalid

Hello all, I''m using the sanitize() method from TextHelper in my application, which appears to use the VERBOTEN_TAGS constant to define which tags to escape out from the HTML. I''d like to modify VERBOTEN_TAGS to include some more tags, but I''m not sure where I would place the necessary code in my rails app. Any ideas? Thanks, Kamil -- Posted via

Hey All, I''m attempting to upgrade my app from rails 2.0.2 to 2.3.3. One bit that''s failing is this call here (in /views/projects/show.html.erb) <%= markdown(@project.description) %> That earns me a: uninitialized constant ActionView::Helpers::TextHelper::Markdown On that line. I''m on a rebuilt machine (windows xp, ruby 1.8.6) so I thought it was a

I have a controller that saves info to the DB. It''s based on the AJAX scaffolding code. All I want to do is add a simple_format() function to it before I save a user-edited text field to the DB. TO convert line returns to <br>s, etc. @project_note = ProjectNote.new(params[:project_note]) @project_note.body = simple_format(@project_note.body) Since this happens in a controller,

All, I have a little namespace collision here. I am trying to use both RubyfulSoup (an HTML parser - which I highly recommend by the way) and the ActionView::Helpers::TextHelper class. Within the TextHelper class, there''s an attempt to create a new "Tag" object. However, Tag is also defined in the RubyfulSoup gem and it is _this_ Tag class whose initialize method is

I''m having a problem formatting some text. I have a textarea that I input my text into, which will then be put into an e-mail and sent out. The problem I am having is when there is a single line break. Multiple line breaks work fine (hitting enter twice), but single line breaks don''t seem to work properly. Take the following input: Line1. Line2. Line3. Line4. Using

Hi! I wanna take a stab at implementing better XSS prevention for Rails. This time for real =) I''m wondering what would be the better way, clean everything up with tidy first and then do the rest with regexp or regexp all the way? Anybody done this before? Thanks! Ciao! Florian

I''m a newbie to rails, and really to the whole DRY and MVC thing as well, except where I accidentally fell into things doing it my own way in the past. I''ve got a fairly complex DB structure I want to create an interface for using Rails. Getting simple tables to display, edit, save, not too much problem there. But where I''m having trouble is figuring out where to

Hi, I want to access TextHelper and UrlHelper methods in my model so how i am able to access it ?

E.g. class Xyz include ActionView::Helpers::TextHelper include ActionView::Helpers::UrlHelper Also

You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.<< any ideas ?
