如何通过其他控制者的动作提交表格？

Question

I have form like this:

<%= simple_form_for @category do |f| %>
  <%= f.input :name %>
  <%= f.input :description %>
  <%= f.input :parent_id, collection: @board.subtree, include_blank: false %>
  <%= f.button :submit %>
<% end %>

@category is instance of Board so this :submit tries to run create action from BoardsController . Instead of it, I'd like to run create action from CategoriesController .

How can I do this?

Answer 1

只需添加url选项。

<%= simple_form_for @category, url: category_path(@category) do |f| %>

so yours would look like:

<%= simple_form_for @category, :url => category_path, do |f| %>
 ...
<% end
