When I use ActiveAdmin to edit one Agency, I can select a City and associates it to the Agency. The city is linked to the Agency, but the city is all the times duplicated in the database.
My models:
# agency.rb
class Agency < ActiveRecord::Base
has_many :agency_cities
has_many :cities, through: :agency_cities
accepts_nested_attributes_for :cities, allow_destroy: true
end
# city.rb
class City < ActiveRecord::Base
has_many :agency_cities
has_many :agencies, through: :agency_cities
end
# AgencyCity.rb
class AgencyCity < ActiveRecord::Base
belongs_to :agency
belongs_to :city
end
I read the doc of Activeadmin and added the [:id] permit_parameter, but I still have the problem, I'm very confused.
# admin/agency.rb
ActiveAdmin.register Agency do
permit_params :name, :picture,
cities_attributes: [:id, :name, :description, :_destroy]
form do |f|
f.inputs "Agencies" do
f.input :picture, as: :file
f.input :creation_date, label: 'Creation Date'
f.input :name, label: 'Name'
end
end
f.inputs do
f.has_many :cities do |k|
k.input :name, label: 'City',
as: :select,
collection: City.all.map{ |u| "#{u.name}"}
k.input :_destroy, as: :boolean
end
end
f.actions
end
You are trying to associate the existing cities with an agency, so, you should do it this way:
ActiveAdmin.register Agency do
permit_params city_ids: [] # You need to whitelist the city_ids
form do |f|
f.inputs "Agencies" do
f.input :picture, as: :file
f.input :creation_date, label: 'Creation Date'
f.input :name, label: 'Name'
f.input :cities, as: :check_boxes, checked: City.pluck(&:id) # this will allow you to check the city names that you want to associate with the agency
end
end
end
This will allow you to associate the selected cities to the corresponding agency without creating (duplicating) new cities in the database. I think this is what you are looking for :-)
You can check in the generated html that the option values in the city select input are the name of the city (not the id).
Try this way: collection: City.all.map{ |u| [u.name, u.id]}

I have two models/tabels: room and room_location, that have a one on one relation:
class Room < ApplicationRecord
has_one :room_location
end
class RoomLocation < ApplicationRecord
belongs_to :room
end
And this is what i want to do in my form in rooms.rb:
ActiveAdmin.register Room do
menu parent: 'Rooms'
permit_params :name, :description, room_location_attributes: [:address, :city]
form do |f|
f.inputs 'Roomsdata' do
f.input :name, as: :string
f.input :description
f.has_one :room_location do |t|
t.inputs do
t.address
t.city
end
end
f.actions
end
end
end
The has_one doesnt work and if i do has_many, it says relation "room_locations" does not exist
You should write in the params room_location_id instead of attributes
ActiveAdmin.register Room do
menu parent: 'Rooms'
permit_params :name, :description, room_location_id
form do |f|
address_id = ''
cs = params[:id].present? ? Case.find(params[:id]) : nil
unless cs.nil?
address_id = cs.address.id unless cs.address.nil?
end
f.inputs 'Roomsdata' do
f.input :name, as: :string
f.input :description
f.input :room_location_id , :as => :select, :collection => room_location.order(address: :desc).to_a.uniq(&:address).collect {|room_location| [room_location.address, room_location.id] }, selected: room_location_id
f.input :room_location_id , :as => :select, :collection => room_location.order(city: :desc).to_a.uniq(&:city).collect {|room_location| [room_location.address, room_location.id] }, selected: room_location_id
f.actions
end
end
end
I have something like this:
class Actor < ActiveRecord::Base
attr_accessible :name, :actor_movie_relationships_attributes
validates :name
has_many :actor_movie_relationships, autosave: true
has_many :movies, through: :actor_movie_relationships
accepts_nested_attributes_for :actor_movie_relationships
end
And:
class ActorMovieRelationship < ActiveRecord::Base
belongs_to :movie
belongs_to :actor
validates :movie, :actor, presence: true
end
Since Actor can have many movies, I'd like to paginate the ActiveAdmin form that is used to administer these relationships.
Currently I have this form (which is NOT paginated):
form do |f|
tabs do
tab 'Actor' do
f.inputs 'Basic Information' do
f.semantic_errors *f.object.errors.keys
f.input :name
f.input :deleted
end
end
tab 'Movies' do
f.inputs 'List of movies' do
f.has_many :actor_movie_relationships, heading: '', new_record: 'Add a Movie', allow_destroy: true do |a|
a.input :Movie, collection: Movie.dropdown_names_map.call
end
end
end
end
f.actions
end
Any idea how to add pagination to Movies in this form?
I would like to ask how to customize active admin.
I`m making my own blog and creating admin page using active admin gem.
This has many to many relationship with article and tag through article_tag table.
What I want to do is to add tag from article panel and I was able to show tag view in article panel, but it is not working fine.(I can`t update or remove tag after save once)
http://localhost:3000/admin/articles/new
image
I made the many to many relation with Article and Tag model like this.
article.rb
class Article < ActiveRecord::Base
has_many :article_tags
has_many :tags, through: :article_tags
accepts_nested_attributes_for :article_tags, :allow_destroy => true
end
tag.rb
class Tag < ActiveRecord::Base
has_many :article_tags
has_many :articles, through: :article_tags
end
article_tag.rb
class ArticleTag < ActiveRecord::Base
belongs_to :article
belongs_to :tag
end
And I customized active admin like this.
ActiveAdmin.register Article do
permit_params :title, :description, :url, :image_url, :media, article_tags_attributes: [:article_id, :tag_id, :name, :_destroy, :_edit]
form do |f|
# f.semantic_errors *f.object.errors.keys
f.inputs "Admin Details" do
f.input :title
f.input :description
f.input :url
f.input :image_url
f.input :media
f.input :publish
end
f.inputs "Articles" do
f.has_many :article_tags do |t|
t.input :tag
end
end
f.actions
end
end
But after I saved the article with tag once I can`t update tag or delete tag...
Does anyone know how to fix this?
You forgot to permit :id attribute of article_tag object. It is passed when updating/deleting existing nested object.
ActiveAdmin.register Article do
permit_params :title, :description, :url, :image_url, :media, article_tags_attributes: [:id, :article_id, :tag_id, :name, :_destroy, :_edit]
...
end
Im trying to save a post with category relation.
These are my models
class Post < ActiveRecord::Base
has_many :categorizes
has_many :post_categories, :through=>:categorizes
accepts_nested_attributes_for :post_categories
end
class PostCategory < ActiveRecord::Base
has_many :categorizes
has_many :posts, :through=>:categorizes
end
class Categorize < ActiveRecord::Base
belongs_to :post
belongs_to :post_category
end
and in ActiveAdmin post.rb.
ActiveAdmin.register Post do
permit_params :title, :content, post_category_ids:[:id]
index do
selectable_column
id_column
column :title
column :post_category_id
column :created_at
actions
end
filter :created_at
form do |f|
f.inputs "Post Details" do
f.input :title
f.input :content,:input_html => { :class => "tinymce_editor" }
#f.input :post_categories, :as=> :check_boxes#, :collection => PostCategory.all
end
f.has_many :post_categories ,new_record: false do |c|
c.inputs do
c.input :title
end
end
f.actions
end
controller do
defaults :finder => :find_by_slug_url
end
end
I need to see my all categories from post_categories and i should select more than one.
i check in rails console but the post hasnt any category.
Post.First.post_categories equal to []
Try post_category_attributes instead of post_category_ids

I have a nested form in ActiveAdmin for these models (a :class_section has_many :class_dates):
class ClassDate < ActiveRecord::Base
belongs_to :class_section
validates :start_time, :presence => true
validates :end_time, :presence => true
end
and
class ClassSection < ActiveRecord::Base
belongs_to :class_course
has_many :class_dates
belongs_to :location
accepts_nested_attributes_for :class_dates
end
Everything seems to be in the right place when I look at the form. However, when I update a class_date, it doesn't save.
ActiveAdmin.register ClassSection do
permit_params :max_students, :min_students, :info, :class_course_id, :location_id
form do |f|
f.inputs "Details" do
f.input :class_course, member_label: :id_num
f.input :min_students, label: "Minunum Students"
f.input :max_students, label: "Maxiumum Students"
f.input :location
end
f.inputs do
f.input :info, label: "Additional Information"
end
f.inputs "Dates" do
f.has_many :class_dates, heading: false do |cd|
cd.input :start_time, :as => :datetime_picker
cd.input :end_time, :as => :datetime_picker
end
end
f.actions
end
index do
column :class_course
column :location
default_actions
end
filter :class_course
filter :location
show do |cs|
attributes_table do
row :class_course do
cs.class_course.id_num + " - " + cs.class_course.name
end
row :location
row :min_students, label: "Minunum Students"
row :max_students, label: "Maxiumum Students"
row :info, label: "Additional Information"
end
panel "Dates" do
attributes_table_for class_section.class_dates do
rows :start_time, :end_time
end
end
active_admin_comments
end
end
Here is the ActiveAdmin file for ClassDates:
ActiveAdmin.register ClassDate, as: "Dates" do
permit_params :start_time, :end_time, :class_section_id
belongs_to :class_section
end
Can you see a reason why it's not saving properly?
UPDATE: I added the following code to the AA and it seems to work now:
controller do
def permitted_params
params.permit!
end
end
Let me know if there is a better solution. Thanks.
UPDATE 2: There is one lingering problem however. I am unable to delete ClassDates using this form.
You need to permit nested parameters, but you should never use params.permit!. It's extremely unsafe. Try this:
ActiveAdmin.register ClassSection do
permit_params :max_students, :min_students, :info, :class_course_id, :location_id,
class_dates_attributes: [ :id, :start_time, :end_time, :_destroy ]
form do |f|
# ...
f.inputs "Dates" do
f.has_many :class_dates, heading: false, allow_destroy: true do |cd|
cd.input :start_time, :as => :datetime_picker
cd.input :end_time, :as => :datetime_picker
end
end
f.actions
end
# ...
end
The configuration (and permitted_params) of your ClassDate admin panel has nothing to do with the permitted parameters within the ClassSection admin panel. Treat them as separate controllers within the app.
Adding the allow_destroy: true option to the has_many call will add a checkbox to the form to allow you to delete a class time upon form submission.
