I'm currently working on implementing an ajax request to delete a "budget" (known as "orçamento" in Portuguese). These budgets are associated with a "cadastre", where each cadastre can have multiple budgets. Below, you can find the components involved:
orcamentos_controller.rb
.
.
.
def destroy
@cadastro = Cadastro.find(params[:cadastro_id])
@orcamento = @cadastro.orcamentos.find(params[:orcamento_id])
@orcamento.destroy
respond_to do |format|
format.js { head :ok }
end
end
def index
@cadastro = Cadastro.find(params[:cadastro_id])
@orcamentos = @cadastro.orcamentos.paginate(page: params[:page], per_page: 10)
end
.
.
.
index.html.erb
... <%= render "orcamentos_lista" %> ...
_orcamentos_lista.html.erb
<table class="table">
<% @orcamentos.each do |orcamento| %>
<tr id="remove_orcamento_<%= orcamento.id %>">
<td>
<%= link_to "Orçamento nº #{orcamento.id}, registrado em #{orcamento.created_at.strftime("%d/%m/%Y")}", "#", class: "list-group-item", type: 'button'%>
</td>
<td>
<%= link_to "Excluir", orcamento, method: :destroy, remote: true %>
</td>
</tr>
<% end %>
</table>
<% content_for :js do %>
<% @orcamentos.each do |orcamento| %>
$('#remove_orcamento_<%= orcamento.id %>').bind('ajax:success',
function(){
$('#orcamento_<%=orcamento.id%>').remove();
}
);
<% end %>
<% end %>
routes.rb
.
.
.
resources :cadastros do
resources :orcamentos
end
.
.
.
An error that I encounter is
undefined method orcamento_path for #<#<Class:0x007f5f39757930>:0x007f5f39cf1eb8><%= link_to "Excluir", orcamento, method: :destroy, remote: true %>As I am still learning Ruby and Rails, please forgive any coding mishaps or mistakes.
