I have a method in a controller file that I want activated only when a  
button is pressed. That what i do

#index.html.erb#

\<%= button\_to ‘Export POINT’, :controller =\> ‘my\_controller’, :action =\>  
‘create\_file\_txt’ %\>

#my\_controller.erb#

def create\_file\_txt  
.  
.  
end

#init.rb#

permission :view\_button\_exp, {:controller =\> :my\_controller, :action =\>  
:create\_file\_txt}, :require =\> :member
