Ive seen some other questions, but none of them seem to help.

Basically here is my controller:

  def append
  y = Post.find(params[:id])
  y.tags_will_change!
  y.tags.push(params[:x].to_i)
  y.save!
  Post.find(params[:id]).tags
redirect_to root_path
    end

and I get this error, PG::InvalidTextRepresentation at /posts/22/append ERROR: array value must start with "{" or dimension information.

Request parameters
{"x"=>"9", "controller"=>"posts", "action"=>"append", "id"=>"22"}

Note: tags is defined as an integer type array => true (i.e. an integer array)

Post model migration:

class AddTagsToPosts < ActiveRecord::Migration
  def change
    add_column :posts, :tags, :integer, array: true, default: []
  end
end

from schema.rb :

  create_table "posts", force: :cascade do |t|

t.integer  "tags",          default: [],              array: true

Ive checked the other answers on here, but none seemed to help.

Show your Post model migration.. – Arup Rakshit Feb 19 '15 at 08:10
and are you getting On rails console can you try `p = Post.first` `p.tags.class` `p.tags.push(2)` – Sonalkumar sute Feb 19 '15 at 08:14
show the full file from your schema.rb file for the Post model. – Arup Rakshit Feb 19 '15 at 08:22
