Question

I am trying to use formtastic to make a form where I can enter an :opposition choose a :venue and a :team and then be presented with a list of players that I am able to check off to select them for the

I have got the form set up so it renders correctly however when submitted it does not save any information and just reloads the page.

My code is at my github here: https://github.com/jpknegtel/st_francis

models

This concerns the following models:

player

 has_many :player_fixtures
 has_many :fixtures, :through => :player_fixtures

fixtures

 has_many :player_fixtures
 has_many :players, :through => :player_fixtures

PlayerFixture

belongs_to :player
belongs_to :fixture

controller

def create
@fixture = Fixture.new(params[:fixture])
if @fixture.save
  flash[:notice] = "Fixture Created"
  redirect_to(:action =>'list')
else
  flash.now[:error] = "Could not save fixture. Please re-enter information"
  render('new')
end
end

def new
 @fixture = Fixture.new
end

form

<%= semantic_form_for :fixture do |f| %>
 <%= f.inputs do %>
  <%= f.input :opposition  %>
  <%= f.input :team, :as => :select, :collection => Team.all %>
  <%= f.input :venue, :as => :check_boxes, :collection => Hash[Venue.all.map{|b| [b.name, b.id]}]%>
  <%= f.input :players, :as => :check_boxes, :collection => Hash[Player.all.map{|b| [b.full_name, b.id]}], :required => true  %>
<% end %>
<%= f.actions do %>
 <%=  f.action :submit, :as => :button %>
 <%=  f.action :cancel, :as => :link %>
<% end %>
<% end %>

So when the form is submitted now nothing is passed. When looking at the web brick server nothing gets submitted but the page just gets reloaded.

It is possible to insert the records using rails console.

EDIT: I can now see this when submitted.

Answer 1

My guess is massassignment. You need to allow rails to update some attributes via massassignment.

Add this line to your fixtures model:

attr_accessible :players_attributes, :opposition, :team_id, :venue_id, :date

This allows rails to set these attributes via new and update_attributes methods.

See the rails guide on security for more information.
