form_for update method - ruby-on-rails-3

Question

On a page I have task listed out. I want to put a form for that task as an update to complete that task. I have the following code as a form_for:
<%= form_for :event, :action => :update, :id => event.id do |f| %>
<%= f.check_box :complete %>
<%= f.submit 'Complete %>
<% end %>
With this code I want it to edit the event with the id in the url and complete the event. What it does it creates a new event instead. Any ideas?
Event Controller:
class EventsController < ApplicationController
layout 'events', :except => 'edit'
# GET /events
# GET /events.json
def index
#events = Event.order("events.initials ASC, events.priroty ASC")
#archived = CompleteEvent.order("complete_events.created_at ASC")
respond_to do |format|
format.html # index.html.erb
format.json { render json: #events }
end
end
# GET /events/1
# GET /events/1.json
def show
#event = Event.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: #event }
end
end
# GET /events/new
# GET /events/new.json
def new
#event = Event.new
#users = ['BG', 'BD', 'MB', 'AF', 'RA', 'JM']
#name = ['Brad Garrison', 'Brian Davis', 'Matt Broach', 'Alan McFarland', 'Russell Anderson', 'Jason Milam']
respond_to do |format|
format.html # new.html.erb
format.json { render json: #event }
end
end
# GET /events/1/edit
def edit
#event = Event.find(params[:id])
#users = ['BG', 'BD', 'MB', 'AF', 'RA', 'JM']
#name = ['Brad Garrison', 'Brian Davis', 'Matt Broach', 'Alan McFarland', 'Russell Anderson', 'Jason Milam']
end
# POST /events
# POST /events.json
def create
#event = Event.new(params[:event])
respond_to do |format|
if #event.save
user = #event.name
Notifier.task_created(user).deliver
format.html { redirect_to #event, notice: 'Event was successfully created.' }
format.json { render json: #event, status: :created, location: #event }
else
format.html { render action: "new" }
format.json { render json: #event.errors, status: :unprocessable_entity }
end
end
end
# PUT /events/1
# PUT /events/1.json
def update
#event = Event.find(params[:id])
#save = #event.update_attributes(params[:event])
#complete = CompleteEvent.new(:initials => #event.initials, :name => #event.name, :event_name => #event.event_name, :complete => #event.complete, :event_description => #event.event_description, :comment => #event.comment)
respond_to do |format|
if #event.update_attributes(params[:event])
if #event.complete == true
user = #event.name
#save
#complete
#complete.save
#event.destroy
format.html { redirect_to :controller => :events, :action => :index}
format.json { head :no_content }
elsif #event.complete == false
Notifier.task_updated(user).deliver
format.html { redirect_to :controller => :events, :action => :index}
format.json { head :no_content }
end
end
end
end
# DELETE /events/1
# DELETE /events/1.json
def destroy
#event = Event.find(params[:id])
#event.destroy
respond_to do |format|
format.html { redirect_to events_url }
format.json { head :no_content }
end
end
end

Answer 1

In edit.html.erb (or your partial that is rendered in edit.html.erb) use:
<%= form_for #event do |f| %>
You generally do not need to specify the action, since it is inferred from the URI path, and Rails knows the id for the model object is #event.id.

Answer 2

What I was missing was that my form was in a loop. Therefore when I was calling the form_for #event it couldn't see outside of that loop. I had the function take on the variable of event.
<% #events.each do |event| %>
......
......
<% form_for event do |f| %>
.....
<% end %>
