I'm trying to get started with active admin. I have this models:
class Client < ActiveRecord::Base
has_many :direcctions
validates :empresa, :presence => true
validates :fono, :presence => true
validates :giro, :presence => true
accepts_nested_attributes_for :direccionts
end
class Direction < ActiveRecord::Base
belongs_to :client
has_one :city
accepts_nested_attributes_for :city
end
class City < ActiveRecord::Base
belongs_to :direction
end
In my Activeadmin.register block for Client I have:
ActiveAdmin.register Cliente do
form do |f|
f.inputs do
f.input :empresa
f.input :fono
f.input :giro
end
f.inputs "Direcciones" do
f.has_many :directions do |j|
j.input :direction
# j.inputs "Ciudad" do
# j.has_one :ciudads do |r|
# r.input :city
# end
# end
end
end
f.buttons
end
end
With this i cant add multiple directions to one cliente, but i can't show the inputs to add a city to a Direction... how can i do that?? and this don't work to.. i have also this error when i try to create a client:
unknown attribute: client_id
Thanks in advance...
ActiveAdmin uses Justin French's Formtastic gem, so you can use that DSL directly in your forms, for example:
f.inputs "Direcciones" do
f.semantic_fields_for :directions do |j|
j.input :direction
j.inputs "Ciudad" do
j.semantic_fields_for :ciudads do |r|
r.input :city
end
end
end
end

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
See more here.
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.
