redirect using a form - ruby-on-rails

Question

this form (views/workers/_form.html.erb) redirects me to the index of tasksadmins, after I push the 'create tasksadmin' button.
I want it to redirect me to "workers/index" and change the button to 'update the task'.
how can I do that please?
<%= form_for(#tasksadmin) do |f| %>
<% if #tasksadmin.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#tasksadmin.errors.count, "error") %> prohibited this tasksadmin from being saved:</h2>
<ul>
<% #tasksadmin.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%= f.hidden_field :admin_mail, :value => #tasksadmin.admin_mail %>
<%= f.hidden_field :worker_mail, :value => #worker_mail %>
<%= f.hidden_field :task, :value => #tasksadmin.task %>
<div class="field">
<%= f.label :done %><br />
<%= f.check_box :done %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
and this is my workers_controller:
class WorkersController < ApplicationController
# GET /workers
# GET /workers.json
def index
#tasks_worker = Tasksadmin.where(:worker_mail => "alon.shmiel#gmail.com")
respond_to do |format|
format.html # index.html.erb
format.json { render json: #workers }
end
end
# GET /workers/1
# GET /workers/1.json
def show
#task_worker = Tasksadmin.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: #worker }
end
end
# GET /workers/new
# GET /workers/new.json
def new
#worker = Worker.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: #worker }
end
end
# GET /workers/1/edit
def edit
#tasksadmin = Tasksadmin.find(params[:id])
#worker_mail = "alon.shmiel#gmail.com"
end
# POST /workers
# POST /workers.json
def create
#worker = Worker.new(params[:worker])
respond_to do |format|
if #worker.save
format.html { redirect_to "#worker", notice: 'Worker was successfully created.' }
format.json { render json: #worker, status: :created, location: #worker }
else
format.html { render action: "new" }
format.json { render json: #worker.errors, status: :unprocessable_entity }
end
end
end
# PUT /workers/1
# PUT /workers/1.json
def update
#worker = Tasksadmin.find(params[:id])
respond_to do |format|
if #worker.update_attributes(params[:worker])
format.html { render action: "index", notice: 'Worker was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: #worker.errors, status: :unprocessable_entity }
end
end
end
# DELETE /workers/1
# DELETE /workers/1.json
def destroy
#worker = Tasksadmin.find(params[:id])
#worker.destroy
respond_to do |format|
format.html { render action: "index" }
format.json { render json: #worker }
end
end
end

Answer 1

In your controller, you have to redirect to the appropriate path like so:
def update
redirect_to "workers/index"
end
I would suggest using path helpers so if you have your routes set up as resources, you can do this:
redirect_to workers_path
As for changing the the button text, just change it to:
f.submit("update the task")

Answer 2

You create a form for an object #tasksadmin, which in your WorkersController#edit is set as follows:
#tasksadmin = Tasksadmin.find(params[:id]
This means that that parameter contains an object of class Tasksadmin, if you let rails build the path for the a Tasksadmin, it will send you to the TasksadminsController#update, and that is why your code does not work. You never get to the WorkersController#update. Check your logs to verify that.
Let me be very clear about this: you should not edit Tasksadmin objects in the WorkersController.
I do not understand why you would do that.
