Then in the view I want to display some bio: <em><%= @user.bio.title %></em><br /> <%= @user.bio.city %><br /> <%= @us...

Until a week ago I was happily coding html.erb files in Notepad++ with syntax highlighting. Then my hard drive crashed. I reinstalled Notepad++ on my new system but when I open my html.erbs, only a few of them are highlighting properly. I think the problem might be that most of these files are being considered 'normal text files', whe...
I have some trivial markup that looks like the following: <li class="someclass"> <=% t'model.attr' %> </li> Is there a trivial way to comment that out? Just wrapping <!-- --> around the block will still leave the ruby code available to the template. This means I have to comment out the HTML and Ruby specific code separately. What's...
My goal is to highlight <basename>.<extension>.erb files as I would highlight <basename>.<extension> files. As a first pass, I'm fine with supporting <basename>.<filetype>.erb, which I tried to do with au BufNewFile,BufRead *.erb setf <afile>:r:e But this doesn't seem to be working. What should I be doing? ...

How can I print data, usually html, in erb? Sometimes it is just impossible to do everything in the controller, like so print "you are funny" in a red div, with a big structure and print "you are hilarious" in a blue div with simple structure I cannot store them in a variable in the controller n then print it in erb and the <%= %> ...
In Rails 3, when a scaffold is generated for instance for a 'Category' the will be a categories_path (and a edit_category_path(@category), ...) used in the erb views. This is not a variable that can be found anywhere and probably is generated. However in my case, for a different entity, Article, I first generated the model and then the ...
How would you port this front-end logic from erb to jsp/jstl? <%= error_messages_for :foo %> Is there any Java library that does something similar? ...
I want to render an HTML-EMail and send it to our customers using some ERB Templates. The basic code I am using: ERB.new("newsletter.html.erb").result(binding) doesn't allow me to add partials to the html.erb-File. I would love to move the header and footer to a partial and use the render :partial-Method in that call. Is this possib...
I'm a big Haml/Sass fan. Right now I work with a designer who prefers Erb and doesn't speak Haml. I find that working with Erb is slowing me down considerably, and it doesn't seem fair that he should have to pay for that time (he's the client & I'm paid hourly). The erb->haml converter works quite well these days, but I don't know if t...

I'm just getting started with Ruby and Ruby on Rails, so excuse me if this is a simple question. I've noticed that in some ERB files, there is a difference to using <%= %> and <% %>, but what is the difference? Thanks! ...
in ruby you can do conditional block like so block do |n| puts n end if foo == bar which would translate into erb as <% block do |n| %> <%= n %> <% end if foo == bar %> is there a way to achieve this in haml other than wrapping the block in a condition? ...
I have no trouble making typical AJAX calls to and from Rails(3) with JSON objects and jQuery-rails (jQuery library plus a special rails.js file). In one controller, though, I want to RETURN some JSON in an erb template (create.js.erb) after an AJAX call. I've tried every combination of things in the controller (@object.to_json, '[{"co...
