Add link on edit form for activeadmin - ruby-on-rails-5

I need to add a link/button in the middle of the form in ActiveAdmin. I try to add action for has_multiple fields but it doesn't work:
form
..
f.has_many :colors, sortable: :position, sortable_start: 1 do |a|
a.input :name
a.action :cancel, :as => :link, :url => "/path"
end
end

Perhaps something like this?
f.has_many :colors, sortable: :position, sortable_start: 1 do |a|
a.input :name
div do
link_to("My custom action", custom_path(:some_parameter => a.object.id), :method => :post)
end
end

password value does not appear inside textbox on edit

I have a non-user model and it has attrs/db-columns, as "password" and there is one more "other password", for both when edited that object, their value do not appear inside textboxes
I did not find any suspicious code inside activeadmin-0.5.1 which would cause this.
Any hints?
Even if I use defaults or put the following, I get the same result
form do |f|
f.inputs "Details" do
f.input :user, :as => :select
f.input :type, :input_html => { :disabled => 'disabled' }
f.input :password
f.input :extra
f.input :other_password
end
f.actions
end
Seems like some filter on any field being edited having 'password' in its name ?
This is most likely due to formtastic's inferred field types, turning any field matching 'password' to be of type :password. Try setting those inputs using the :as => :string option:
form do |f|
f.inputs "Details" do
f.input :user, :as => :select
f.input :type, :input_html => { :disabled => 'disabled' }
f.input :password, :as => :string
f.input :extra
f.input :other_password, :as => :string
end
f.actions
end

Rails 3 - how to assign the value to nested attributes before calling save in update action

Models associations are
document.rb
has_many :sections
accepts_nested_attributes_for :sections, :allow_destroy => :true, :reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } }
section.rb
belongs_to :document
has_many :paragraphs, :dependent => :destroy
has_many :contents :through => :paragraphs
validates :user_id, :presence => { :message => "Must be filled" }
paragraph.rb
attr_accessible :user_id, :section_id, :content_id
belongs_to :section
belongs_to :content
validates :user_id, :section, :content, :presence => { :message => "Must be filled" }
paragraphs table just like a intermediate table for sections and contents and I want to save records in documents, sections and paragraphs table using single submission.
So I designed form as like
_form.html.erb
<%= form_for #document, :validate => true do |f| %>
<%= f.error_messages %>
<%= f.text_field :name %>
<% f.fields_for :sections do |builder| %>
<%= builder.text_field :name %>
<%= builder.select :content_ids .... {:multiple => true} %>
<% end %>
<% end %>
example parameters when submiting the form
{"document"=>{"name"=>"sdf", "sections_attributes"=>{"0"=>{"name"=>"sdf", "description"=>"sdf", "_destroy"=>"0", "content_ids" => ["1", "2"]}}, "commit"=>"Update Document", "id"=>"3"}
In additionally, I am updating current_user's id to user_id column of paragraphs table.
update
#document = Document.find(params[:id])
#document.attributes = params[:document]
#document.sections.each {|section|
section.user_id = current_user.id
section.paragraphs.each {|paragraph| paragraph.user_id = current_user.id}
}
if #document.save!
# success
else
render :action => 'edit'
end
I got "Validation failed: User Must be filled".
Is validation triggered when assigning attributes using object.attributes= as above

undefined method `has_many' for Formtastic

I'm getting this error :
undefined method `has_many' for #<Formtastic::SemanticFormBuilder:0xb410d4c>
It work when I use it like this :
ActiveAdmin.register Ressource do
form do |f|
f.inputs do
f.input :offer_id, :as => :hidden
f.input :name
f.input :category, :include_blank => false, :collection => Category.order('place ASC').all, :member_label => :to_label
f.input :description, :input_html => {:class => 'editor'}
f.input :price
end
f.has_many :roles do |app_f|
app_f.inputs do
if not app_f.object.id.nil?
app_f.input :_destroy, :as => :boolean, :label => "Supprimer l'utilisateur du lot"
end
app_f.input :user, :member_label => :to_label, :label => 'Assigné le lot'
app_f.input :name, :include_blank => false
end
end
f.buttons
end
end
But it doesn't work in a partial, i need to call the has_many method by a different way or something else ?
ActiveAdmin extends formtastic with some useful helpers such as has_many (lib/active_admin/form_builder.rb in the activeadmin gem).
Unfortunately, these helpers are not available by default in your templates.
Here are two options:
If you don't need the extra has_many functionality (it looks like active_admin adds some javascript to make it easy to add a new record to the collection), then you can use stock formtastic. This example should work fine in the activeadmin file as well as in a partial:
ActiveAdmin.register Ressource do
form do |f|
# ...
f.inputs :for => :roles do |app_f|
# ...
app_f.input :name, :include_blank => false
end
f.buttons
end
end
Use the ActiveAdmin form builder explicitly:
<%= semantic_form_for [:admin, #resource], builder: ActiveAdmin::FormBuilder do |f| %>
<!-- ... -->
<%= f.has_many :teachers do |app_f| %>
<%= app_f.inputs do %>
<!-- ... -->
<% end %>
<% end %>
<%= f.buttons %>
<% end %>
I hope this helps.
There is a solution
form :html => {:multipart => true} do |f|
end
Or, if you want to use partial:
<%= active_admin_form_for [:admin, #resource] ,:html => {:multipart => true} do |f|%>
<% end %>

How to handle multiple nested resources in ActiveAdmin?

I'm using ActiveAdmin (0.4.0) with Rails (3.1.1).
I can't find a nice way/hack to handle multiple nested resources.
Considerer 3 models as:
class Program < ActiveRecord::Base
has_many :knowledges, :dependent => :destroy
end
class Knowledge < ActiveRecord::Base
belongs_to :program
has_many :steps, :dependent => :destroy
end
class Step < ActiveRecord::Base
belongs_to :knowledge
end
And the ActiveAdmin resources:
ActiveAdmin.register Program do
end
ActiveAdmin.register Knowledge do
belongs_to :program
end
ActiveAdmin.register Step do
belongs_to :knowledge
end
In routes.rb:
namespace :admin do
resources :programs do
resources :knowledges do
resources :steps
end
end
end
Here's the urls for the index of the programs, the knowledges and the steps :
http://localhost:3000/admin/programs
http://localhost:3000/admin/programs/1/knowledges
http://localhost:3000/admin/programs/1/knowledges/1/steps
No problem for the "Knowledge" admin but the "Step" admin don't keep the nested context.
For example, when I use filters in steps#index I'm redirected to:
http://localhost:3000/admin/knowledges/1/steps?params...
But it must have been:
http://localhost:3000/admin/programs/1/knowledges/1/steps?params...
Same problem when I create a new resource:
http://localhost:3000/admin/knowledges/1/steps/new
Instead of:
http://localhost:3000/admin/programs/1/knowledges/1/steps/new
Same problem with the breadcrumb... etc...
What I've tried so far in app/admin/steps.rb:
ActiveAdmin.register Step do
belongs_to :knowledge
config.clear_action_items!
action_item :only => :index do
link_to('Create Step', new_admin_program_knowledge_step_path(knowledge.program.id, knowledge.id))
end
index do
column :id
column :knowledge
column :title
column "Actions" do |step|
link_to("Voir", admin_program_knowledge_step_path(step.knowledge.program, step.knowledge, step), :class => "member_link show_link") +\
link_to("Editer", edit_admin_program_knowledge_step_path(step.knowledge.program, step.knowledge, step), :class => "edit_knowledge member_link edit_link", :id => "knowledge_#{dom_id(knowledge)}") +\
link_to("Supprimer", admin_program_knowledge_step_path(step.knowledge.program, step.knowledge, step), :class => "member_link delete_link", :method => :delete, :confirm => "Delete?")
end
end
filter :id
filter :title
filter :subtitle
filter :stage_type
filter :order_by
filter :created_at
filter :updated_at
form :partial => "form"
end
And in app/views/admin/steps/_form.html.erb I must use the activeadmin formbuilder:
<%= semantic_form_for(resource, :url => admin_program_knowledge_steps_path(resource.knowledge.program, resource.knowledge), :builder => ActiveAdmin::FormBuilder) do |f|
f.inputs "Step" do
f.input :knowledge, :as => :hidden
f.form_buffers.last << f.template.content_tag(:li, f.template.content_tag(:label, "Knowledge")+f.template.content_tag(:p, f.object.knowledge.title))
f.input :title
f.input :order_by
end
f.buttons
end %>
Well... I'm stuck.
How to handle this nicely? Any clues appreciated...
Well, the solution is pretty simple...

end

Adding name value with link_to

I'm using a link_to to create an object in my Rails 3 app. Searching has given me the proper way to use link_to with the :post method, but I'm wondering if using link_to to pass in a name value for my object as well. Here is my link:
<%= link_to "Todo text", {:controller => "profiles", :action => "create_inside", :method => :post}, :class => "button white" %>
My profiles_controller.rb:
def create_inside
#todo = Insidetodo.new
#todo.save!
if #todo.save
redirect_to #profile.todo, :notice => 'Todo successfully added.'
else
render :action => 'new'
end
end
My todo.rb model:
class Todo < ActiveRecord::Base
has_and_belongs_to_many :profiles
validates :name, :presence => true
end
Is there a way to add in :name => "#{#user.profile.todotext}" to the link_to so that it passes and saves? I don't know if it's creating properly because at the moment when I click a link_to I get a validation error - Validation failed: Name can't be blank.
For passing name in the link_to
<%= link_to "Todo text", {:controller => "profiles", :action => "create_inside", :name => "#{#user.profile.todotext}", :method => :post}, :class => "button white" %>
and the controller must be
def create_inside
#todo = Insidetodo.new(:name => params[:name])
if #todo.save
redirect_to #todo.goal, :notice => 'Todo successfully added.'
else
render :action => 'new'
end
end
But the link_to will pass the name parameter in url only(like Todo text).
If you want the name not to be sent in the url, you might want to use a form and use a submit button instead of the link as it is representing an action and not a link.
<%= form_tag(:controller => "profile", :action => "create_profile") do -%>
<%= hidden_field_tag :name, #user.profile.todotext %>
<%= submit_tag "Todo Text" %>
<% end -%>
