Rails link from one model to another based on db field?
- by Danny McClelland
Hi Everyone,
I have a company model and a person model with the following relationships:
class Company < ActiveRecord::Base
has_many :kases
has_many :people
def to_s; companyname; end
end
class Person < ActiveRecord::Base
has_many :kases # foreign key in join table
belongs_to :company
end
In the create action for the person, I have a select box with a list of the companies, which assigns a company_id to that person's record:
<%= f.select :company_id, Company.all.collect {|m| [m.companyname, m.id]} %>
In the show view for the person I can list the company name as follows:
<%=h @person.company.companyname %>
What I am trying to work out, is how do I make that a link to the company record?
I have tried:
<%= link_to @person.company.companyname %>
but that just outputs the company name inside a href tag but links to the current page.
Thanks,
Danny
