Original Post:
please help solve the problem.
There is a table users:
id :integer, autoincrement
name :string
gender_id :integer
There is a table genders:
id :integer, autoincrement
gender_name :string
model User:
class User < ActiveRecord::Base
belongs_to :gender
end
model Gender:
class Gender < ActiveRecord::Base
has_many :users
end
I need the gendername. I try to do so:
<% @users.each do |user| %>
<div class="col-xs-6"><%= user.name %></div>
<div class="col-xs-2"><%= user.gender_id %></div>
<% end %>
the result is output number, but I need to gendername
p.s.
so I tried:
<div class="col-xs-2"><%= user.gender.gender_name %></div>
in this case receives the following error message:
undefined method `gender_name' for nil:NilClass
Dear All,
I think that this post raises interesting issues regarding the gathering of
a user's gender. The developer is evidently not requiring user indication
of gender, and has problems in the event of null. Perhaps that matter is
optional. If so, why didn't the developer provide an option for "User
Declines" as an example. But generally I think this matter is very
important. We exist in the 21st Century where a request for gender must be
done with sensitivity. What is the convention in this matter?
Thanks,
Liz
