That is not important. You cannot assign a value to a variable and
then pass it to an action, you must do it using the url of the link
to. The easiest way is to pass it as a parameter to the url, so the
url will look something like
htttp://localhost:3000/operations/some_action?value=73. You can
easily do this with something like link_to("label",
:controller="operations", :action="some_action", :value=73). Then in
the action in the operations controller the variable params[:value]
will have the value 73.
Note, however, that if in the operations controller all you want to do
is redirect to another action in order to edit an article, for
example, which is what I understood you wanted to do a few posts ago,
then don't go to the operations controller at all, just construct the
correct link so that the button takes you straight to the activities
controller edit action so the edit page is displayed when the button
is clicked.
