(I'm having some hard time for days to manage to chose a random item
from teh database and to be able to pass it further.)
It is basic operation and i tried several ways all, brought me to the
same problem, params {"id" = "random"} <- the name of the controller
method
controller:
def random # method works checked it in the console. Returns a valid
obj.
@task = Task.find(rand(Task.first.id..Task.last.id))
render "random"
end
random.html.erb
<%= @task %> # i want it to make it work, if i pass manually
lets #say `../random/1` lets say as an example it works it shows me the
memory #location of the object.
error log:
ActionController::ActionControllerError in TasksController#show
Cannot redirect to nil!
