Redirect_to problem

Hi all,

I tried to post this yesterday, but it seems to have been lost in the
void,
so reposting.

I’m having a problem with redirect_to preserving the HTTP verb, in this
case PUT, when redirecting.
I send an AJAX PUT request to to an action in TasksController, and want
to
redirect to the show action in the TaskListsController when processing
is
complete like the following:

redirect_to @tasklist, :notice => t(‘successful’)

From the docs I would assume this would sent a GET /task_lists/1, but
instead is sending PUT /task_lists/1, causing the update action to be
called…

Controllers:
class TasksController < ApplicationController
def move_task_down

def move_task_down
@task = Task.find(params[:id])

respond_to do |format|
  if @task.move_lower
    format.html { redirect_to @task.task_list, :notice

=> t(‘task_lists.successfully_moved’) }
else
format.html { redirect_to @task.task_list, :alert =>
t(‘task_lists.error_move_task’) }
end
end
end
end

class TaskListsController < ApplicationController
def show
@task_list = TaskList.find(params[:id], :include => [:tasks])
respond_to |format|
format.html
end
end
def update
# usual update stuff
end
end

Models:
class Task < ActiveRecord::Base
belongs_to :task_list
end

class TaskList < ActiveRecord::Base
has_many :tasks, :order => ‘position asc’, :dependent => :destroy
end

routes.rb:
put ‘tasks/:id/move_down’=> ‘tasks#move_task_down’, :as =>
‘move_task_down’
resources :task_lists

development.log:

Why is the redirect_to using PUT and not GET?
Any advice would be greatly appreciated.

Thanks,

Please paste in the output from rake routes here. I am guessing that the
show of a task_list is somehow scoped to PUT, but I’d be hard-pressed to
guess what that might mean. You might try disambiguating the issue in
your redirect call by using the REST helper:

task_list_path(@task.task_list)

instead of redirecting to the bare object (which I agree, is supposed to
work).
