Why So Scared » Ruby on Rails http://www.whysoscared.com A blog about; Programming, Music and Random Stuff Thu, 10 Jun 2010 02:43:11 +0000 http://wordpress.org/?v=2.8.5 en hourly 1 select_tag / select input into my database rails http://www.whysoscared.com/select_tag-select-input-into-my-database-rails/ http://www.whysoscared.com/select_tag-select-input-into-my-database-rails/#comments Tue, 22 Dec 2009 16:59:50 +0000 Juo http://www.whysoscared.com/?p=346 In my posts form the input to the model can only be Dog or Cat, I’ve constructed the following code and assumed it would work, however the information input into the select_tag box was never going into my database.

<% form_for(@post) do |f| %>

    <%= f.label :title %><br />
    <%= f.text_field :title %>

    <%= f.label :source %><br />
    <%= select_tag :source,  options_for_select([ "Dog", "Cat") %>

    <%= f.submit 'Create' %>

<% end %>

I finally got this to work by using;

1
 
<%= f.select(:source, options_for_select({ : Dog =>'Dog',:Cat =>'Cat'} %>

If you put the options in a hash then they will be output in a random order, to output the options in a chosen order they need to be put into an array, this left me with the following code.

View

<%= f.label :source %><br />
<%= f.select(:source, options_for_select(@source)) %>

@source = [['Dog'],['Cat'],]
