Hi all, I'm going nuts on a very simple issue. I know what I want but don't know what to tell rails to do so. I have a very common setup for managing contacts. A companies table and a contacts table. As you've guessed it's a one to many relationship. The database is setup with the appropriate foreign keys, the models have been generated and I added the "has_many :contacts" and "belongs_to :company" to the appropriate models Having put scaffolds in place and wanting to add a contact, when saving I get: ActiveRecord::AssociationTypeMismatch in Work#create Company expected, got String (I don't now what "Company" represents in this case (model, column or what not) What I eventually want when adding a contact is having a dropdown list with the company names so the relation is established. I have the agile book, and the example webshop was a very clear. But I can't seem to implement this. Are there any easy online step-by-step tutorials how to go about this, because I'm losing it. Thanx a lot! Regards, Gerard.

Hi all again, Finally getting somewhere. The relationship thingy seems to be nailed. I'm afraid of working with scaffold, because I can't oversee the impact worry I might loose code. So I'll do it the manual way. Nevertheless do I have a question on the code below. The dropdownlist is in place. but now al the fields need to be filled. Since I have 20 fields for a contact. Is it possible to generate the label - text_field - label - text_field - etc. iteration dynamically with a loop. (Seems more managable like that). Here's the catch: The company.id field needs to be ignored because that's already in the drop downlist. <h1>New contact</h1> <form action="/work/create" method="post"> <b>Company</b><br/> <select name="contact[company_id]"> <% @companies.each do |company| %> <option value="<%= company.id %>"> <%= company.name %> </option> <% end %> </select> # From here on <p><label for="contact_firstname">Firstname</label><br/> <%= text_field 'contact', 'firstname' %></p> <p><label for="contact_lastname">Lastname</label><br/> <%= text_field 'contact', 'lastname' %></p> ..... # And another 18 entries like the two up here. </form> Thanx a lot.

It's strange you got such message about Compagny that sit on another table. Please post back your models, and generated controllers & view. attachments are prefered.

So I'll do it the manual way. There's also a manual way but using the right Helpers : http://api.rubyonrails.com/classes/ActionView/Help...
