当用户离开评论时,会创建新评论和项目。我试图通过新评论表单将旧项目与新评论相关联,但是无论何时创建新评论,它都会在评论表item_id部分中获取新项目标识符,而不是在新评论表单中显示的旧项目标识符。一次性创建多个模型
型号:
class Item < ActiveRecord::Base
has_one :comment
class Comment < ActiveRecord::Base
belongs_to :Item
评论控制器:
def create
@comment = Comment.new(comment_params)
@comment.create_item (line_id: @comment.line_id, view_dc_id: @comment.view_dc_id, irankdez_id: @comment.item.irankdez_id,
outputs_id: @comment.item.outputs_id, DataKeitimo: Time.current)
if @comment.save
redirect_to line_path(@comment.line_id, line_id: @comment.line_id, view_dc_id: @comment.view_dc_id, irankdez_id: @comment.item.irankdez_id, outputs_id: @comment.item.outputs_id), :flash => {:notice => "New Item is created!"}
else
...
end
end
评论表单视图:
<%= simple_form_for(@comment) do |f| %>
<%= f.hidden_field :item_id,
:value => params[:item_id] %> #passing old item_id over params
<%= f.hidden_field :line_id,
:value => params[:line_id] %>
<%= f.hidden_field :view_dc_id,
:value => params[:view_dc_id] %>
<
<%= f.hidden_field :outputs_id,
:value => params[:outputs_id] %>
<%= f.text_field :body, :required => true %>
<label for="textarea1">Komentaras</label>
<%= f.submit 'Submit', :class => 'btn' %>
<% end %>
请帮助我。
