"Undefined Attribute Method"

Rails
1

I couldn’t find any other source to solve my problem, so I’m posting
here I have a controller “candidates”

class CandidatesController < ApplicationController
def new
@candidate = Candidate.new
end
end

A table model called candidate with lots of validations.

I create my new.html.erb and whenever I try to open it I get this
error message:

undefined method `define_attribute_methods’ for nil:NilClass

Extracted source (around line #3):

1:

Yeni Basvuru


2:
3: <% form_for @candidate do |t|%>
4:

5: <%= t.label :name,“Isim”%>
6: <%= t.text_field :name%>

Please help me out!

I’d say that the most likely problem is that you’ve managed to define
a method (or have an attribute with a name) that clashes with a
standard ruby or activerecord method.
Do you have a method or column named class by any chance?

I have these:

t.string “school”
t.string “class”

That would be a yes then.

That “class” attribute is probably your problem.
