ActionView is a very useful class, in its own right. But, calling it by itself causes a weird crash, exiting Ruby, without even raising an exception! ruby script/runner "begin; av = ActionView::Base.new; av.render(:inline => ''Hi!''); rescue => e; puts e; end" just crashes Ruby. Same with render(:file => ''template.rhtml'') Why is this? What is the proper way to use ActionView to render a template? -- Posted via http://www.ruby-forum.com/.
Oops. Forgot the "puts". Works fine when rendering inline templates. But I can''t get the same syntax to work to render :file => filename.

I did more testing, and think I may have found a bug: You can use ActionView freestyly to do compile_and_render_template - but, if you give it a file to load itself, Ruby crashes. No exception, no error, just the intepreter exits. (I''m running Windows. Perhaps on Linux it would dump core?). Example: av = ActionView::Base.new t = "/path/to/template/file.rhtml" av.render_file(t, false) # crash -- Posted via http://www.ruby-forum.com/.

Must be a windows issue - I still get a Ruby crash - not even an exception, the intepreter just crashes. What OS are you running?

Basically, when ActionView tries to raise an exception because it can''t find the file to render, if it was invoked freestyle, it crashes rather than produce an error. Only in Windows though. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
