Updating a form containing array of text fields with has_man

I’ve got a User class and an Employer class set up as follows:

User.rb:
has_many :employers

Employer.rb
belongs_to :user

My tables are as follows:

mysql> select id,first_name,last_name from users limit 5;
±----±-----------±----------+
| id | first_name | last_name |
±----±-----------±----------+
| 711 | Patrick | Stewart |
| 714 | Larry | Davis |

mysql> select * from employers limit 5;
±—±---------±-------------------±-------------------------±-------+
| id | user_id | employer_name | position | months |
±—±---------±-------------------±-------------------------±-------+
| 1 | 711 | Test Company | Administrative Assistant | 12 |
| 2 | 711 | Company 2 | Recruiter |
15|
| 3 | 711 | Apple | Developer | 0 |
| 4 | 711 | test | test position
| 0 |
| 5 | 714 | Google | programmer | 0 |
±—±---------±-------------------±-------------------------±-------+

I’d like to provide a single form with an array of fields for
employer_name,
position and months, so that I can allow a user to update/create their
employer information, but I can’t figure out how to get rails to
automagically create the associations between the user object and the
employer object. Right now my form partial looks like this:

_employers.rhtml:

<%= text_field 'employer', 'employer_name' %> <%= text_field 'employer', 'position' %> <%= text_field 'employer', 'months' %>

but I need some way to add the user’s id to the employer record when
it’s
created. I was hoping I could do something like this:

<%= text_field ‘user’, ‘employer[employer_name][]’ %>

but it doesn’t work… (undefined method `employer[employer_name][]’ for
#User:0x888595c). So it looks like I may have to take care of the
associations and record updating manually, but I just thought I’d check
with
the list to see if there might be something I’m missing.

if anyone has any suggestions, please let me know. Thanks,

Mike
