Hi I’m trying to customize the link_to helper and keep getting this
error,
any suggestion how can I work arround it?
this is the error message:
undefined method link_to' for moduleUserHelper’
this is my users_helper.rb:
module UsersHelper
alias_method :link_to_original, :link_to
alias_method :link_to, :link_to_permission
def link_to_permission(name, options = {}, html_options = nil,
*parameters_for_method_reference)
if @permission
if html_options
html_options = html_options.stringify_keys
convert_options_to_javascript!(html_options)
tag_options = tag_options(html_options)
else
tag_options = nil
end
url = html_escape(options.is_a?(String) ? options :
url_for(options,
*parameters_for_method_reference))
“<a href_1234=”#{url}"#{tag_options}>#{name||url}"
else
link_to_original( name, options,
html_options,*parameters_for_method_reference )
end
end
end
alias_method :link_to_original, :link_to
Isn’t it:
alias link_to_original link_to
or the other way around:
alias link_to link_to_original
but no commas, and no :interns
hi, followed your suggestion, still having the same problem:
NameError in #
undefined method link_to' for moduleUsersHelper’
