link_to - Going Back without knowing the action name.
Hi,
I have a bunch of link_to''s in my code that are simple Back buttons that
should basically just go to the previous request. Is there a way of doing
this without specifying the action to execute? The problem is, sometimes I
may render the same view through separate actions so I wouldn''t know which
action to go back to.
Thanks.

adding an onclick option to link_to method
Hello,
I''m trying to use the rail link_to to open a popup window and then
print the popup window at the same time. Is there a way to add
another "onclick" option to tell the popup to print? I know how to do
this in javascript but not sure how to use the rails help to do it. I
also am aware that the link_to_function method is used to call a
javascript function.

Rails: View specs and implicit parameters in link_to()
Hi all,
I''ve been cleaning up our routing file, and removed the default
map.connect ":controller/:action" route.
It''s thrown up a bunch of sloppy mistakes, which is great, but I also
think I''ve found a problem with the view specs.
We have a generic navbar partial which is rendered in the index page
of several different controllers. The navbar contains

link_to :post true Newbie question
Hi All,
I am attempting to use a link_to helper to perform a form post using the
following construct:
<%= link_to ''Save'', {:action =>''create''}, :post => true %>
What I find is the parameters passed to the webserver are empty. My
model validation stuff triggers indicating the fields in question are
empty too. This is to create a new DB entry so no

session[:return_to] for going back.
Hi,
Is session[:return_to] something Rails maintains to quickly go back to the
previous uri without having to keep track of the action name? Or, do we
have to actually set it in our actions?
Thanks.

How to extend a helper using plugin?
Hello,
I''m facing this problem while trying to extend the parse_redmine_links
helper method in Redmine-1.1.0 (Rails-2.3.5) from my plugin.
My idea is to use alias_method_chain so the extended version could
call the original version and adjust the result to it''s liking.
Anything I''ve tried so far exposes this behavior: the first render of
a page uses the extended

How-to spec this helper method?...
Hey gang,
I have this dead-simple method defined in a helper:

''category'', :object => Category.new

Where, and mostly how, would I spec this? I haven''t been able to find

helper spec not finding rails core helpers
Hi,
My helper specs were going ok until I added a call to a rails
DateHelper method in one of my helpers
http://api.rubyonrails.com/classes/ActionView/Helpers/
DateHelper.html#M000574
The helper runs fine from my view templates, just dies in the spec test.
I boiled my question down to a simple (not too useful) example. I''m
not sure what I''m missing.
