Rails: duplicating information into another model if conditions met -

i've got list of articles checkboxes on form. when box checked, body of selected article copied 1 of x text areas.

should user want make change body of article in text area need send change through controller new rails model (called edit).

i have record being created, need application record changes new edit record. here's relevant controller code:

new

def new   @template = template.find(params[:template])   @article_count = @template.pages-1   @doc = doc.new   @doc.template_id = @template.id   @doc.user_id = current_user.id   @articles = current_user.brand.articles   respond_to |format|     format.html     format.json { render json: @doc }   end end 

create

def create   @doc = doc.new(params[:doc])   respond_to |format|     if @doc.save       #make editable version       if current_user.brand.try(:editable?)         @doc.articles.each |article|           @edit = edit.new           @edit.name = article.name           @edit.video = article.video           #something here bodies of text areas           @edit.article_id = article.id           @edit.doc_id = @doc.id           @edit.user_id = current_user.id           @edit.save         end       end       @doc.create_activity :create, owner: current_user       format.html { redirect_to share_url(@doc.user.ftp, @doc) }       format.json { render json: @doc, status: :created, location: @doc }     else       format.html { render action: "new" }       format.json { render json: @doc.errors, status: :unprocessable_entity }     end   end end 

and here's code makes text areas in view.

<% @article_count.times |article| %>   <div id="edit<%= article %>" class="tab-pane <%= "active" if article == 0 %>">     <%= text_area_tag("edit[#{article}][body]") %>   </div> <% end %> 

records created each article, can't seem able save edits text areas. it's kind of nested-form arrangement. @ appreciated. cheers!

i've solved breaking form 2 pages: 1 handles selection, second editing. given doc has many edits, method made part 2 of form:

def edit_content   @doc = doc.find(params[:id])   if !@doc.edits.exists?     @doc.articles.reverse.each |article|       @doc.edits.build(:body => article.body)     end   end end 

hope helps someone.
