No "name" method error but I have a method

Question

  <div class="field">
    <%= f.label :name %><br>
    <%= f.text_area :name %>
  </div>

  <div class="field">
    <%= f.label :content %><br>
    <%= f.text_area :content, :cols =>20, :rows => 20 %>
  </div>

  <div class="actions">
    <%= f.submit %>
  </div>

<%= f.text_area :name %> line is causing the error. When I remove it, it works fine.

Above lines are for when creating a new status...when I click on the "new status" button, error shows up. please help. Thank you!

We need to see the 'form' line, the error, the exact line the error references, the model schema, and the 'new' action from the relevant controller. — Philip Hallstrom, Feb 01 '14 at 07:18
is there any specific cause to define `<%= f.text_area :name %>` twice, in single `form`? — rony36, Feb 01 '14 at 07:58
I suspect your form would be better suited to a text_field for `:name` anyway. Do you actually have a `name` attribute in your model? — Jon, Feb 01 '14 at 09:40
It's not defined twice, I think he just made a mistake when posting the question. — nktokyo, Feb 01 '14 at 10:14
Is "name" permitted in the controller? Rails 4 has new ways of restricting access to fields. — nktokyo, Feb 01 '14 at 10:20

The no method error either means you don't have a name attribute defined in the table, or you don't have the name method in your model

attr_accessor

You have to remember that Rails is basically a bunch of classes all strung together; and models use the attr_accessor ruby method to create the attributes of your objects

The ways you could fix your error are:

Ensure you have a name column (attribute) in your DB
Ensure your model is retrieving said name attribute (you're not using .select())
Use attr_accessor to create a name attribute
Use alias_attribute to create the name attribute from another

Without seeing your other code, this should help:

#app/models/model.rb
Class Model < ActiveRecord::Base
    attr_accessor :name
end
