Sending Records from a new View

Question

I created a new action knowledges on my controller responsabilities and created a view called nested_knowledges. I made the action , render this view. I put the following code in this view:

    <%= form_tag edit_responsability_path do -%>
            <% for @responsability in Responsability.find(:all)-%>
                <% for knowledge in Knowledge.find(:all) %>
                    <%= check_box_tag "responsability[knowledge_ids][]", knowledge.id, @responsability.knowledges.include?(knowledge)  %>
                    <%= knowledge.nome %>
                    <br/>
                <% end %>
            <% end %>
<div class="actions">
    <%= submit_tag l(:send) %>
    <br/>
</div>

It renders a has_and_belongs_to_many relationship between Responsabilities and Knowledges tables.

I put the form_tag, because if I create the form_for it displays an error. But when I click on my send button, the Knowledges records that Responsability has, it says that there is no route, as in the error below:

Started POST "/responsabilities/1/edit" for 127.0.0.1 at 2014-06-03 12:00:24 -0300

What I need to do to get these records sent?

Answer 1

Better you split that question, you have several questions together in one question.

But, answering the Routes error

if you included in your route.Rb the following line

resources :responsabilities

You have a list of pre-generated routes, in which case you have placed the following path in your form_tag

edit_responsability_path

this path does not have a POST method. will generate something from tp /respo.. /{id}/Edit

If you want to access the controller update method, I suggest doing

<%= form_tag responsability_path, method: :put do -%>

Or if you want to access this route with a post you have to put in Routes.Rb something like.

resources :responsabilities do
  member do
    post 'edit'
  end  
end
