I've looked for this exhaustively on StackOverflow and Google but found no answer to help me out, so I'm asking this though I know the subject has been hardly discussed here.
I have a HABTM relation between Contests and Subjects, my log shows de array of id's when posting a new contest or editing an existing one, but it simply doesn't record anything in my postgres DB.
I'm using ActiveAdmin 1.0 and Rails 4
Below follows my code:
class Contest < ActiveRecord::Base
attr_accessor :subjects_ids
has_and_belongs_to_many :subjects
belongs_to :examination_board
belongs_to :bureau
belongs_to :role
belongs_to :degree
belongs_to :career
end
class Subject < ActiveRecord::Base
attr_accessor :contests_ids
has_many :questions
has_and_belongs_to_many :contests
end
ActiveAdmin.register Contest do
permit_params :name,
:year,
:state,
:city,
:examination_board_id,
:role_id,
:degree_id,
:career_id,
:bureau_id,
subjects_ids: [:id]
# scope :states
index do
column "Nome", :name
column "Banca Examinadora", :examination_board
column "Matérias" do |subject|
div :class => 'subjects' do
subjects = ['yo','la','ho'].join(', ')
end
end
actions
end
form do |f|
f.semantic_errors
f.inputs
f.input :subjects, as: :check_boxes, collection: Subject.all
f.actions
end
end
My log:

I appreciate any suggestion, thank you all!
Well, it turns out that I was not far from making it. My only problem was this line:
subjects_ids: [:id]
I shouldn't have put that ":id" plus the correct name is "subject_ids".
That's it, it works like a charm now.

I am implementing counter_cache concept to my Forums app. It is working fine for one model that has a simple belongs_to association but not working for a polymorphic association.
My app structure is like this. I have 3 models, Forum, Post and Comment.
class Forum < ApplicationRecord
has_many :posts
end
Post Model:
class Post < ApplicationRecord
belongs_to :forum, counter_cache: true
has_many :comments, as: :parent
end
Comment Model:
class Comment < ApplicationRecord
belongs_to :parent,polymorphic: true, counter_cache: true
has_many :comments, as: :parent
end
My Comments Model is basically a polymorphic one, so a comment can belong to a post or a comment can belong to another comment (in this way it will be considered a reply of a comment)
I have a posts_count field in Forum model which is working fine and auto-incrementing and decrementing is working.
I also have a comments_count field in Post model.
Whenever a new comment is created, the comments_count field is incremented in the associated Post.
But when I try to create a comment whose parent (polymorphic association) is another comment (so basically a reply of a comment), I hit an error:

ActiveModel::MissingAttributeError (can't write unknown attribute `comments_count`):
What am I missing here? Any hint would be really appreciated, Thanks!!
I have got it working by removing counter_cache: true from Comment model and defining my own methods for increment and decrement of the counter in Comment model. So here is my final Comment model:
class Comment < ApplicationRecord
belongs_to :parent,polymorphic: true,touch: true
has_many :comments,dependent: :destroy,as: :parent
after_create_commit { self.parent_post.increment!(:answers_count,1) }
after_destroy { self.parent_post.decrement!(:answers_count,1) }
def parent_post
(self.parent if parent_type == "Post") || self.parent.parent
end
end
If anyone comes up with another answer please post it here. Thanks.
The counter_culture counter cache gem supports polymorphic associations natively: https://github.com/magnusvk/counter_culture
I cannot seem to find out why my has_many record will not save. I've test with has_one in the models and it works fine but when I change it to has_many it doesn't work. I've check a few simular stackoverflow posts and I seem to have this correct but it doesn't work. Nested form in activeadmin not saving updates & ActiveAdmin Form not saving nested object
This is for Rails version 5.1.0.alpha and Activeadmin version 1.0.0.pre4
I do not get any errors nor do I see the nested object get created though I see the params when I create an object here is the output

I was able to patch by adding in ActiveAdmin.register
controller do
def create
#section = AbqDistricts::District.create!(permitted_params[:abq_district].as_json)
redirect_to admin_faq_sections_path, notice: "Section was successfully created!"
end

This is just a patch. Notice and the only way it worked is if I used .as_json
it would not work with to_json or just the params alone

Finally installing gem locally in rails 5 application works for me.
instead of using github path
gem 'activeadmin', github: 'activeadmin'
i have used following activeadmin version.
gem 'activeadmin', '~> 1.0.0.pre4'
The best way to overcome this is for you to override the activeadmin create action, you can do something like this
controller do
def create
#course = Course.new(permitted_params[:course])
super
end
end
I have three models, Team, Player and TeamMembership. TeamMembership defines the many-to-many relationship between Team and Player. When creating a new Team, the user gets 11 dropdown menus, each containing all the available players. However, a Player can only have a single membership with a Team, which is what I want to validate.
class Player < ActiveRecord::Base
has_many :team_memberships
has_many :teams, :through => :team_memberships
end
class Team < ActiveRecord::Base
has_many :team_memberships
has_many :players, :through => :team_memberships
accepts_nested_attributes_for :players, :team_memberships
validates_associated :team_memberships
end
class TeamMembership < ActiveRecord::Base
belongs_to :team
belongs_to :player
validates_uniqueness_of :player_id, scope: :team_id
end
# GET /teams/new
def new
#team = Team.new
11.times { #team.team_memberships.build }
end
<%= f.fields_for :team_memberships do |team_memberships_form| %>
<%= team_memberships_form.label :player_id %>
<%= team_memberships_form.select(:player_id, options_from_collection_for_select(#Player.available, :id, :name)) %>
<br />
<% end %>
When trying to create a new team, the following appears in the dev log. (Edited down to only 3 players for brevity)

As can be seen, because of the way I save the records through accepts_nested_attributes_for, validation does not reflect the actual SQL which will run.
How do I get the behaviour that I want?
Worked around this by adding a custom validation method to the Team model.
validate :unique_players
def unique_players
player_ids = team_memberships.map { |ft| ft.player_id }
if player_ids != player_ids.uniq
errors.add(:team_memberships, "must have unique players.")

Completed 500 Internal Server Error in 669ms
ArgumentError (too few arguments):
app/controllers/dogs_controller.rb:7:in `format'
app/controllers/dogs_controller.rb:7:in `create'
Don't know why this is true since I have in my model:
class Dog < ActiveRecord::Base
attr_accessible :name, :category_ids
belongs_to :user
has_many :categorizations
has_many :categories, :through => :categorizations
accepts_nested_attributes_for :categories
validates :name, :presence => true
validates :user_id, :presence => true
end
As you can see the join table is Categorizations:
class Categorization < ActiveRecord::Base
belongs_to :dog
belongs_to :category
belongs_to :cat
belongs_to :mouse
end
And I select the categories desired on the form. Here's the model:
class Category < ActiveRecord::Base
attr_accessible :name
belongs_to :user
has_many :categorizations
has_many :dogs, :through => :categorizations
has_many :cats, :through => :categorizations
has_many :mouses, :through => :categorizations
validates :name, :presence => true, :uniqueness => true
before_validation :downcase_name
private
def downcase_name
self.name = self.name.downcase if self.name.present?
end
end
For some strange reason it still assigns the categories when looking in the database but this may be causing other issues i'm having. What could be the problem?
UPDATE
Here is my Dog form:
<%= form_for(#dog, :remote => true) do |f| %>
<%= f.label :name, "Name" %>
<%= f.text_field :name %>
<%= f.label :category, "Categories" %>
<%= f.select :category_ids, Category.all.collect {|c| [c.name, c.id]}, {}, { :multiple => true, } %>
<% end %>
Still get the Mass-assignment error when I try:
attr_accessible :name, :category_ids
WARNING: Can't mass-assign protected attributes: category_id
attr_accessible :name, :category_id, :category_ids
# It says this for each category I want to put on the Dog.
WARNING: Can't mass-assign protected attributes: category_id
attr_accessible :name, :category_id
WARNING: Can't mass-assign protected attributes: category_ids
UPDATE 2
I was able to get rid of the ArgumentError though by adding the respond_to for the controller action:
def create
#dog = current_user.dogs.new(params[:dog])
respond_to do |format|
if #dog.save
format.js
else
format.js
end
end
end
If add 2 or more categories to the Dog ( in this case 3) . It adds them in the database and does mass assign them but server keeps saying this in the log:

Is this a problem if it's technically working?
You have an extra s here:
class Dog < ActiveRecord::Base
attr_accessible :name, :category_ids
...
category_id is a column on the dogs table, So, just remove it:
class Dog < ActiveRecord::Base
attr_accessible :name, :category_id
I needed to change this:
#dog = current_user.dogs.new(params[:dog])
To this instad:
#dog = current_user.dogs.build(params[:dog])
And then it started to work for me.
