So I’m not even sure if I’ll be able to properly explain what I’m
trying to do, but I’ll do my best.
Let’s say that I have two models: Document and Option.
A Document has many Options (and, by extension, an Option belongs to a
Document).
Each document may have a different number of options, hence why I made
it a separate model.
Each document has the following fields: “name” and “content”.
Each option has the following fields (aside from the obvious
“document_id”): “name”, “hint”, and “value”.
I would like to create a form for a document, with nested fields for
that document’s options. The tricky part is that I would like to use
the fields listed above in my builder, for instance for the hint or
label.
I’m sorry if I’m not making myself very clear. I’ve tried to put
together an example with pseudo code for what I would like to do. I’ve
put what I want to have appear as follows expected value.
<% semantic_form_for @document do |f| %>
<% f.inputs do %>
<%= f.input :name %>
<%= f.input :content %>
<% end %>
<% f.inputs :name => ‘Option #%i:’, :for => :options do |c| %>
<%= c.input :value, :label => option “name” field, :hint =>
option “hint” field %>
<% end %>
<% f.buttons do %>
<%= f.commit_button ‘Submit’ %>
<% end %>
<% end %>
For example, let’s say my document has the following three options:
Option 1:
name = “color”
hint = “Please provide the color name.”
value = “”
Option 2:
name = “brand”
hint = “Please provide the brand name.”
value = “”
Option 3:
name = “age”
hint = “How old are you?”
value = “”
I’d like the form to provide the label for each of the three options
using the “name” field, and then use the “hint” field to provide the
form input hint. If I understand things correctly, at the very least,
my example should already store the user input for each option in the
“value” field.
Here are my models in case you need them:
Document.rb:
class Document < ActiveRecord::Base
has_many :options, :dependent => :destroy
accepts_nested_attributes_for :options
end
Option.rb:
class Option < ActiveRecord::Base
belongs_to :document
end
I would really appreciate any help or suggestions.
