ruby on rails - Nested attributes not being inserted into table -

i have situation 1 of nested fields being passed parameters not being inserted table.

my model company has_one :incorporation. incorporation has, right anyway, 1 field, nested company form follows

<%= simple_form_for @company, url: url_for(action: @caction, controller: 'incorporations'), html: {id:"incorporationform"}, remote: false, update: { success: "response", failure: "error"} |company| %>     ...     <%= company.simple_fields_for :incorporation |f| %>         <div class="padded-fields">             <div class="form_subsection">                 <%= f.input :trademark_search, as: :radio_buttons, label: 'would trademark search , provide advice regarding issues identify in relation name have selected?', input_html: { class: 'form-control radio radio-false' } %>             </div>         </div>     <% end %>     ... <% end %> 

the new , create methods in controller follows

def new     @user=current_user     @company = @user.companies.build     @incorporation = @company.build_incorporation     @action = "new"     @caction = "create"     @remote=false end  def create     @snapshot="incorporation"     @company = current_user.companies.build(company_params)     @incorporation = @company.build_incorporation      if @company.save         current_user.companies << @company         if params[:final_submit]             redirect_to incorporations_index_path         else             redirect_to edit_incorporation_path(@incorporation), notice: "successfuly saved incorporation info."         end     else         render 'new', notice: "something went wrong; form unable saved."     end end 

the problem when select 1 of radio buttons in simple fields, log shows data sent parameters:

 parameters: {"utf8"=>"✓",..., "company"=>{..."incorporation_attributes"=>{"trademark_search"=>"0"}},...} 

but not being inserted table. instead, new entry inserted company_id, id, created_at , updated_at, of accurate. there no invalid parameter errors or that.

my strong params this:

def company_params         params.require(:company).permit(:id, :name,...,incorporation_attributes: [:title, :trademark_search, :user_id, :employee_stock_options, :final_submit, :submit, :_destroy],...) end 

so somehow parameters not linking table insertion (if makes sense). might going on here?

thanks ideas.

ok, there missing code, think issue here:

@company = current_user.companies.build(company_params) @incorporation = @company.build_incorporation 

in first line create company model incorporation model (which present in company_params). second line overrides incorporation model new 1 without data. since incorporation belongs_to company, initial 1 data discarded.

solution: remove second line entirely , work.

other errors:

you not need line:

current_user.companies << @company 

@company has been build on current_user.companies scope, meaning belongs current_user. not cause visible bugs, it's waste of time server.

you missing id within incorporation_attributes - means never able update or delete data via nesting attributes (and have _destroy field, assume @ point).
