Question

I have two related table in my rails application: ephemerides and ephemeris_shared_attributes.

The first one has an ephemedis_shared_attribute_id column and the seconds has columns as year, yday etc.

An ephemeris_shared_attributes is created automatically when I save an ephemeris but there is no value in it.

How can I add a form field to enter for example year and save it in the ephemeris_shared_attributes table?

Here is my current form:

= form_for @ephemeris do |f|

... 


.field
    = f.label :content
    = f.text_area :content
  .field
    = f.label :locale
    = f.select(:locale,['mg','fr'])
  .actions
    = f.submit 'Save'

Answer 1

You need this line in your model Ephemerides:

accepts_nested_attributes_for :ephemedis_shared_attribute

Then in your form:

= form @ephemeris do |f|
  ...
  = f.fields_for :ephemedis_shared_attribute do |f2|
    .field
      = f2.label :year
      = f2.text_field :year
  ...

Hope I didn’t spoil variables, these ephme…things are a little confusing 😀
