Hi,

I cant seem to find the answer to this anywhere so any help/advice is  
appreciated.

Each project has one risk and a risk has a number of has/one belongs to  
assocations. So what i want to do is in my code loop through all the  
associations for a risk and display some field information from each as  
they are pretty similar. So somehting like

\<% for model\_association in project.risks %\>  
\<%= model\_association.model\_name %\>  
\<%= model\_or\_assocation.name %\>  
\<% end %\>

Each association to risk has a filed called name present which i would  
like displayed

Is this possible or whats the best way to something like this?

Ihad to di a bit deeper but found the following in the API

[http://rails.rubyonrails.com/classes/ActiveRecord/Reflection/ClassMethods.html](http://rails.rubyonrails.com/classes/ActiveRecord/Reflection/ClassMethods.html)  
[http://rails.rubyonrails.com/classes/ActiveRecord/Reflection/MacroReflection.html](http://rails.rubyonrails.com/classes/ActiveRecord/Reflection/MacroReflection.html)

reflect\_on\_all\_associations looks like it will do the job

How can i actually i get the value of the object relationship, so the  
code below will output the class name of each association for the risk  
which is a start. So what i want is to display a field value belonging  
to the association

\<% for association in @project.risk.class.reflect\_on\_all\_associations %\>  
\<%= association.name %\>#This will print out the name

```
#So i need to get the association model name where the qoutes are 

```

below  
\<%= @project.material\_risk.“association.name”.field\_value %\>  
\<% end %\>

Can anyone help?
