Hey guys,
I got a serious problem with haml. I have used haml in several
projects, so I am no newbie to haml - however I never had an error
like this:
The problem:
Something like this:
#welcome
#show
#create_ideas_area
%p
= link_to 'Create an idea', new_idea_path, :id =>
'create_idea_link'
causes:
ActionView::TemplateError (undefined method `link_to' for
#<ActionView::Base:0xb61dad24>) on line #5 of app/views/welcomes/
show.haml:
2:
#show
3:
#create_ideas_area
4:
%p
5: = link_to 'Create an idea', new_idea_path, :id =>
'create_idea_link'

The problem is helper-specific, something like that:
#welcome
#show
#create_ideas_area
%p
%a{:href => '#', :title => 'foo'}
is rendered without errors.
Note the script/console output in some working project (on the same
machine):
helper.link_to('foo', '#')
=> "<a href=\"#\">foo</a>"
This doesn't work when i "cd" into the project from above and do a
script/console:
helper.link_to('foo', '#')
NoMethodError: undefined method `link_to' for #<ActionView::Base:
0xb6dd3db0>
from (irb):1
The haml gem is not installed system-wide because i use gem bundler,
the line in "Gemfile" reads:
gem "haml" #(which is the same line in all my projects)
"gem bundle" runs through without any errors.
Any idea what's going on here?
How can I debug this further?
