Update form from another scaffold - ruby-on-rails

Question

I am trying to update a record from the view of another scaffold, the problem is that it sends me the following error:
No route matches {:action=>"update", :controller=>"pedidosliberados"}
I'm showing one form per record
this is my form:
<% #pedidosliberados.each do |pedidoliberado| %>
<tr id="pedido_liberado_<%= pedidoliberado.id %>">
<td class="component_name_body_col"><%=pedidoliberado.try(:Client)%></td>
<td class="component_name_body_col">
<%= form_for(pedidoliberado, :method => :put, remote: true, :url => {:controller =>'pedidosliberados', :action => 'update'}, html: {class: "form-horizontal "}) do |f| %><!--ajax-->
<%= f.text_field :Status, value: "1" %>
<%= submit_tag "Actualizar", class: "btn btn-primary"%>
<% end %>
</td>
</tr>
<% end %>
my route:
resources :pedidosliberados
my action update from controller pedidosliberados:
def update
respond_to do |format|
if #pedidoliberado.update(pedidoliberado_params)
format.html { redirect_to #pedidoliberado, notice: 'Pedidoliberado was successfully updated.' }
format.json { render :show, status: :ok, location: #pedidoliberado
format.js {}
else
format.html { render :edit }
format.json { render json: #pedidoliberado.errors, status: :unprocessable_entity }
format.js {}
end
end
end

Answer 1

The problem is that you are using an incomplete route, that is /update; you need to add the id of the object to be updated, something like /update/12 where 12 is the id of the object. So in your code you could remove the :url attribute and you will be fine.
So your view, now should look like this:
<% #pedidosliberados.each do |pedidoliberado| %>
<tr id="pedido_liberado_<%= pedidoliberado.id %>">
<td class="component_name_body_col"><%=pedidoliberado.try(:Client)%></td>
<td class="component_name_body_col">
<%= form_for(pedidoliberado, :method => :put, remote: true, html: {class: "form-horizontal "}) do |f| %><!--ajax-->
<%= f.text_field :Status, value: "1" %>
<%= submit_tag "Actualizar", class: "btn btn-primary"%>
<% end %>
</td>
</tr>
<% end %>
This works because rails automatically assigns the correct controller and action for your object (when using REST routes).
UPDATE
If you want to explicity assign the url, then use :url like you are doing, but adding :id (remember, you need to specify the id of the object to be updated). So, your form should look something like this:
<%= form_for(pedidoliberado, method: :put, remote: true, url: { controller: 'pedidosliberados', action: 'update', id: pedidoliberado.id }, html: { class: "form-horizontal " }) do |f| %>
