I am a rails newbie and am trying to build my first app. I have a jobs  
and categories controller and models respectively.

CONTROLLER:

def new  
@job = Job.new  
@catergory = Catergory.all

```
respond_to do |format|
  format.html # new.html.erb
  format.xml { render :xml => @job }
end

```

end

#THIS IS A group of 10 RADIO\_BUTTONS TO SELECT A CATEGORY FROM. BY  
DEFAULT THE FIRST ONE IS SELECTED. !!!AM STUCK HOW TO WORK  
IT!!!maybe a partial???

\<%= f.label "Category" %\> \<% @job.catergory.each do | f | %\> \<%= f.radio\_button :name, :id %\> \<% end -%\>
# UPLOAD a file for the logo in the controller???

def upload  
uploaded\_io = params[:job][:logo]  
File.open(Rails.root.join(‘public’, ‘images’,  
uploaded\_io.original\_filename), ‘w’) do |file|  
file.write(uploaded\_io.read)  
end  
end

#VIEW FILE views/jobs/new.html.erb

\<% form\_for (@job, :html =\> {:multipart =\> true }) do |f| %\> \<%= f.error\_messages %\>\<%= f.label "title" %\> \<%= f.text\_field :title %\>   
"Senior Ruby Developer" or "HTML5 CSS3 Guru"

I have 2 models Category and Job. How do I make the user select a  
category from a list of radio buttons in the view/jobs/new form. How  
do I then associate the job with the selected Category. Please help.
