Group,
This might very well be Rails 102 stuff, but it''s doing my little head
in.
Simple request - I want to create a link within my View to fire off a
system call to run an external program.
In this example it''s pretty easy - run a Windows system command that
simply starts something (it''s not what I''m trying to achieve
but it''s
an easy debug method):
def method_to_run
system(''start dir > test.txt'')
end
How the *heck* do I link to this method within my View?
A simple <%= link_to feature, :method => method_to_run %> results in
the following error:
<pre>
undefined local variable or method `method_to_run'' for #<#<Class:
0x46c3248>:0x46c1808>
</pre>
Jason

Reference on link_to here: http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to :method is used for specifying HTTP method such as POST, GET, etc. The parameter that you are passing (method_to_run) is not a valid value for :method. I suggest you define a controller and invoke one of its methods through the link. Example: link_to "Feature", :controller => "mycontroller", :action => "method_to_run" On Tue, Sep 14, 2010 at 9:29 AM, Jason N <freezingkiwis-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Group, > > This might very well be Rails 102 stuff, but it''s doing my little head > in. > > Simple request - I want to create a link within my View to fire off a > system call to run an external program. > > In this example it''s pretty easy - run a Windows system command that > simply starts something (it''s not what I''m trying to achieve but it''s > an easy debug method): > > def method_to_run > system(''start dir > test.txt'') > end > > How the *heck* do I link to this method within my View? > > A simple <%= link_to feature, :method => method_to_run %> results in > the following error: > > <pre> > undefined local variable or method `method_to_run'' for #<#<Class: > 0x46c3248>:0x46c1808> > </pre> > > > Jason > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-talk-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > To unsubscribe from this group, send email to > rubyonrails-talk+unsubscribe-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org<rubyonrails-talk%2Bunsubscribe-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org> > . > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > >-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Of course, I should have known that :method was for the HTTP method. Thanks. I guess i just need to write the correct routes now.
