Params dont get passed to the object?

Question

i'm working on a spanish system for a hospital. I got a scaffold named persona.

Well in my controller i got a "new" and a "create" method, like almost always. I can get to the new_persona view (with form) and enter some datas. The problem is now, when i want to create the person i've inserted, i get the following error:

"ActiveRecord::StatementInvalid in Hds::PersonasController#create"

Furthermore it says me that 2 columns cant be null. Sure, i got the mysql-option that null should be false, because i dont want this 2 columns ever to be empty. The problem is that rails rises this error even when i inserted something in those fields. Hope you understand me and can help me. Here the code:

personas_controller new and create:

def new
  @persona = Hds::Persona.new



  respond_to do |format|
    format.html # new.html.erb
    format.json { render json: @persona }
  end
end


def create
    @persona = Hds::Persona.new(params[:persona])

    respond_to do |format|
      if @persona.save!
        format.html { redirect_to @persona, notice: 'Persona was successfully created.' }
        format.json { render json: @persona, status: :created, location: @persona }
      else
        format.html { render action: "new" }
        format.json { render json: @persona.errors, status: :unprocessable_entity }
      end
    end
  end

form:

<%= form_for(@persona, :validate=>true) do |f| %>
  <% if @persona.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@persona.errors.count, "error") %> prohibited this persona from being saved:</h2>

      <ul>
      <% @persona.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

<table class="form_table">
  <tr class="partial_head">
    <th colspan="2">
      <h3>Datos personales</h3>
    </th>
  </tr>

  <tr>
      <div class="field">
        <td><%= f.label :numero_doc %></td>
        <td><%= f.text_field :numero_doc %></td>
      </div>
  </tr>


[...]

</table>

 f.submit

<% end %>

Thanks for the help!! Greetings, CO

Answer 1

I got it, it should be

params[:hds_persona]

in my create-method.

Thank you!
