提交表单中动态创建的表

Question

I have a dynamically created table inside a form_for . The table consists of an input field in each row. The number of rows inside the table is not constant (and hence the table is created dynamically).

How do I submit all the fields inside the table and route it to a controller action?

Answer 1

You can customize where send your data with url param in form_for helper.

<%= form_for @article, url: {action: "create"} do |f| %>
...

Submit button will send all your rows at method "create" of ArticlesController

form_for(@article, url: my_custompath_articles_path)
...

your data will be transmitted where declared by my_custompath_articles_path in

config/routes.rb

resources :articles do
  collection do
    post my_custompath
  end
end

and

articles_controller.rb

def my_custompath
  ... your code
end
