Question

Im trying to define a select tag in my view.
My view looks like this:

  <div class="field">
<%= f.label :analyst %><br />
<%= select_tag :sub_category_analyst, options_for_select(analyst_names, :selected =>      @sub_category.analyst || 0) %>

and my model looks likes this:

@@analyst_names = ["", "foo", "bar"]

belongs_to :category
has_many :products

 def analyst_name
    @@analyst_names[analyst.to_i || 0]
  end

 def self.analyst_names
    @@analyst_names
  end

The error when trying to load the page is: undefined local variable or method `analyst_names’

Thanks in advance!

Answer 1

I don’t know what your model is called, so I’ll call it MyModel for now.

In your view, you’re going to want to replace analyst_names with MyModel.analyst_names, because otherwise it thinks analyst_names is a local variable in the view, and then it can’t find that variable.

You might benefit from reading about scope (some links about it are here and here).
