Can't mass-assign protected attributes even if I use attr_accessible

Rails
1

Hi,

I’m working on a Rails 3.2.2 application which has JSON APIs and I use a
CLI client for inserting some data. It works fine except for the Author
model. When I try to create a new post (Post belongs_to :author and
Author has_many :posts) I get the following error :

<h1>
  ActiveModel::MassAssignmentSecurity::Error in

PostsController#create

Can’t mass-assign protected attributes: name

I did lots of researches on the topic but I found no working solution
:frowning:

I use attr_accessible to avoid MassAssignent errors and it works for all
others models but not for the “Author” name attribute.

Here is the Author model :

class Author < ActiveRecord::Base
  attr_accessible :name, :email

  extend FriendlyId
  friendly_id :name, use: :slugged

  # some validations

  has_many :posts
  #authlogic
  acts_as_authentic

  # some stuffs
end

Actually, I have disabled whitelist_attributes and it solved my problem
but I suppose that it is not the convenient way to do this (and probably
not a good idea).

My question is : Why the attr_accessible does not work here ? And how
can I solve the problem without disabling the whitelist ?

Thank you,

Revan

I found the solution ! :slight_smile:

The problem was that I used acts_as_taggable_on_steroids plugin which
does not work on Rails 3.2 …

Since “Author” is the only model which has a :name attribute, I thought
that the problem came from Author … but the problem was in the Tag
model (which is in the acts_as_taggable_on_steroid plugin). Indeed, its
:name attribute is not “accessible”.

So, I use the acts_as_taggable_on gem
(GitHub - mbleigh/acts-as-taggable-on: A tagging plugin for Rails applications that allows for custom tagging along dynamic contexts.) which correctly works
on Rails 3.x
