Rails undefined method 'generated_methods' for nil:NilClass
- by mike
Okay so I was just starting this rails app and generated my first model
ruby script/generate model Grid req:string class:string ctitle:string credits:float grade:string pass:boolean
created my table
rake db:migrate
(in C:/Users/Michael/InstantRails/rails_apps/studentGrid)
== CreateGrids: migrating ====================================================
-- create_table(:grids)
- 0.0150s
== CreateGrids: migrated (0.0150s) ===========================================
and went to the console to add some data to my table
Grid
= Grid(id: integer, req: string, class: string, ctitle: string, credits: float,
grade: string, pass: boolean, created_at: datetime, updated_at: datetime)
Grid.create(:req="Math Elective", :class="Math 111", :ctitle="Calculus I", :credits=3.0)
Pretty standard I thought, but then I get this error and I don't understand why
