Blank ActiveAdmin pages - ruby-on-rails

My ActiveAdmin index page for ad_images works fine but new, edit, and view look blank like this...
admin/ad_image.rb looks like this:
ActiveAdmin.register AdImage do
permit_params :name, :url, :imageable_type, :imageable_id
form(:html => { :multipart => true }) do |f|
f.inputs "Ad Image" do
f.input :name
f.input :url, as: :file
f.input :imageable_type
f.input :imageable_id
end
f.actions
end
end
The AdImage model works normally otherwise. Any clue what's going on?
UPDATE
Turns out that "ad_image" conflicts with a formtastic style of the same name... I think? When I remove the "ad_image" class from the form (which is added automatically) everything works fine.
I can give an alias to my ActiveAdmin class like so
ActiveAdmin.register AdImage, as: "ImagesForAds"
... and the form will appear. But now I can't save anything...

Edit admin/ad_image.rb :---
ActiveAdmin.register AdImage do
permit_params :name, :url, :imageable_type, :imageable_id
form do |f|
f.inputs "Ad Image" do
f.input :name
f.input :url, as: :file
f.input :imageable_type
f.input :imageable_id
end
f.actions
end
end

How to show persisted images in ActiveAdmin?

ActiveAdmin automatically pulls up the persisted information for an object when the update form is displayed. It doesn't show the images though - doesn't even show the name in my form - how do I fix this to show the actual image and it's name?
ActiveAdmin.register Art do
permit_params :art_pic_attachments_attributes: [:id, :picture, :_destroy]
form(html: { multipart: true }) do |f|
f.inputs do
f.has_many :art_pic_attachments, allow_destroy: true, heading: 'Images' do |ff|
ff.file_field :picture, required: true, heading: "Pictures"
end
end
f.actions
end
Maybe this wiki article will help. The key is to use an image tag as the input hint.
f.inputs "Attachment", :multipart => true do
f.input :cover_page, :as => :file, :hint => image_tag(f.object.cover_page.url)
f.input :cover_page_cache, :as => :hidden
end

Pass current_admin_user.id into permit_params

In my application I have 2 models: AdminUser, which has_many :announcements, and Announcement, which belongs_to :admin_user. The Announcement table has admin_user_id column in a database.
In app/admin/announcement.rb I have:
ActiveAdmin.register Announcement do
permit_params :title, :body, :admin_user_id
controller do
def new
#announcement = Announcement.new
#announcement.admin_user_id = current_admin_user.id
end
end
form do |f|
f.inputs do
f.input :title
f.input :body, as: :ckeditor
end
f.actions
end
end
Why my controller doesn't work? When I create an announcement through activeadmin, the column admin_user_id is empty. How can I solve this issue?
Just added to a form: f.input :admin_user_id, as: :hidden, and now everything is working.

Active Admin remove certain fields while going for updation

Hi i have an admin page using active admin gem.
thing is while creating a new page i should be able to input name, amount and interval..But while updating only name field must show..other 2 values shouldnt be updated. This is my active admin file. How to make this happen. Thanks in advance
ActiveAdmin.register SubscriptionPlan do
menu priority: 10
permit_params :name, :amount, :interval
index do
selectable_column
default_actions
column :name
column :amount
column :interval
end
form do |f|
f.inputs "Subscription Plan" do
f.input :name
f.input :amount
f.input :interval, as: :select, collection:["week","month","year"]
end
f.actions
end
end
Try this
form do |f|
f.inputs "Subscription Plan" do
f.input :name
if f.object.new_record?
f.input :amount
f.input :interval, as: :select, collection:["week","month","year"]
end
end
f.actions
end

manipulating the h3 title with an activeadmin has_many form

I looked at this question and was able to get set up a has_many form properly.
Here's where I'm at:
f.has_many :related_contents do |rc|
rc.inputs "first configuration" do
#...
end
end
f.has_many :related_contents do |rc|
rc.inputs "second configuration do
#...
end
end
so I want to have different configurations of fields. What I can't figure out is how to set the <h3> that activeadmin generates and sets as the title for the nested fields. I thought something like
f.has_many :related_contents, :title => "first set" do |rc|
would work, but It does not. Does anybody know what I need to do to get this working right?
I assume that changing the <h3> will also change the button that gets generated to add. Is there another option I need to set for that as well?
Add a :heading option to the f.has_many method
f.has_many :related_contents, :heading => "first set" do |rc|
#...
end
To remove the heading altogether, set it to false or nil
$('h3:contains("Related Contents")').hide().first().show();
Not perfect, but it definitely looks better.
you need to follow the next order, i mean, you need to set on first line the "inputs" and then the "has_many" block, I hope this is what you are looking, regards!
form do |f|
f.inputs "details #1" do
f.input :title, :label => "Title"
f.input :description, :label => "Description"
f.input :image, :as => :file, :required => false, :label=>'Image'
end
f.inputs "details #2" do
f.has_many :subdetails do |a|
a.input :description, :label => "Description"
a.input :image, :as => :file, :required => false, :label=>'Image'
end
end
Ok, after have some problems with the title of has_many I could figure out how is the correct way for do it and i think is more cleaner and fancy...
form do |f|
f.inputs "Post" do
f.input :title
f.input :description
end
f.inputs "Comments" do
f.has_many :comments do |a|
a.input :title
a.input :description
end
end
f.buttons
end

activeadmin: adding delete for a nested resource

I have a infrastructure object composed for many datacenters. In the apps/admin/infrastructures.rb I have the following code:
form do |f|
f.inputs "Infrastructure details" do
f.input :name
f.has_many :datacenters do |datacenter_form|
datacenter_form.input :name
end
end
f.buttons
end
I can add datacenters with no problems but I don't know how I can delete it from infrastructure form.
Sep 2017 Update:
Rails 5.1.4, ActiveAdmin 1.0.0
Append :id and _destroy in permit_params along with other attributes from the model e.g. :name in your case. Then provide the :allow_destroy option in f.has_many too. Other requirements remain the same; like adding allow_destroy: true in accepts_nested_attributes_for.
Final look:
ActiveAdmin.register Infrastructure do
permit_params :name, datacenters_attributes: [:id, :_destroy, :name]
form do |f|
f.inputs "Infrastructure details" do
f.input :name
f.has_many :datacenters, heading: false,
allow_destroy: true,
new_record: false do |datacenter_form|
datacenter_form.input :name
end
end
f.buttons
end
end
ActiveAdmin Reference
This worked for me:
i.input :_destroy, as: :boolean
and in the Model remember to add :allow_destroy :
accepts_nested_attributes_for :images, allow_destroy: true
Solved adding the following line:
datacenter_form.input :_destroy, :as => :boolean, :required => false, :label => 'Remove'
The code looks like:
form do |f|
f.inputs "Infrastructure details" do
f.input :name
f.has_many :datacenters do |datacenter_form|
datacenter_form.input :name
datacenter_form.input :_destroy, :as => :boolean, :required => false, :label => 'Remove'
end
end
f.buttons
end
If you cant destroy the object nested. You need to put :_destroy in your app/admin/object.rb permit_params
permit_params :id,:name, :cod, :_destroy
I hope this will be helpful (I've changed my code to suit your example, so I hope there are no typos here):
form do |f|
f.inputs "Infrastructure details" do
f.input :name
f.has_many :datacenters do |datacenter_form|
datacenter_form.inputs :datacenters do
datacenter_form.input :name
end
datacenter_form.buttons do
link_to "Delete", admin_datacenter_path(datacenter_form.object), method: "delete", class: "button" unless datacenter_form.object.new_record?
end
end
end
f.buttons
end
and the controller method should be defined in datacenters.rb
controller do
def destroy
#datacenter = Datacenter.find(params[:id])
#datacenter.destroy
redirect_to edit_admin_retailer_path(#datacenter.infrastructure)
end
end
This should work:
datacenter_form.label :_delete
datacenter_form.check_box :_delete
This adds a checkbox for each nested object which will delete the object if checked.
Don't forget to add the following to your parent model
has_many :child_name, :dependent => :destroy
