Bug: NoMethodError: undefined method 'guide_category_id'

[andrewhavens]

There is an application error when you try to create a new guide:

NoMethodError: undefined method `guide_category_id' for #Guide:0x007f1f6f1cd140
app/views/guides/new.html.erb:18 · block in _app_views_guides_new_html_erb__618379928909969980_69886491947920

Looks like it's a problem with the form element:

<%= f.select :guide_category_id, @guide_categories.map { |gc| [gc.name, gc.id] }, {}, {class: 'form-control'} %>

I already ran the database migrations:

Migrating to AddGuideCategoryIdToPosts (20150901091113)
== 20150901091113 AddGuideCategoryIdToPosts: migrating ========================
-- add_column(:posts, :guide_category_id, :integer)

We can't seem to be able to reproduce the issue :/. I even checked out your master on my machine, ran migrations and all, and it seems to be working just fine. And, the build is working, and I think there was a test for exercising this functionality.

The guide_category_id field is a db field, so the only explanation I can think of is that somehow the migration didn't run. Or it ran in a different environment?
