Here is the code I use to generate a select list of Companies.
<%= f.association :company, :collection => Company.order('name ASC'), :label => "Company: ", :include_blank => false %>
Now the table is pre-populated with a special record "id:1, name:none", I want to exclude this record as a selectable option in the select list that's generated. How can I go about accomplishing this?
Thanks!
Try this
<%= f.association :company, :collection => Company.where("id != 1").order('name ASC'), :label => "Company: ", :include_blank => false %>
Or
In the controller
#companies = Company.where("id != 1").order('name ASC')
In the view
<%= f.association :company, :collection => #companies, :label => "Company: ", :include_blank => false %>

I am new to ruby on rails and active admin, I need to create check boxes for registration fees. while I checked, the value from checkbox is not saved to the database. can anyone help me ??
form do |f|
f.inputs do
f.input :name, label: "Student Name"
f.input :dob,:label => "Date of Birth"
f.input :age,:label => "Age"
f.input :gender, as: :radio, :label => "Gender", :collection => [ "Male", "Female"]
f.input :reg_fee, :as => :check_boxes, :collection => RegChargeSetup.all.map{|v| ["#{v.reg_fee}"]}
end
f.actions
end
From your code, you are taking array of arrays, instead you should take array of strings,
So, change
f.input :reg_fee, :as => :check_boxes, :collection => RegChargeSetup.all.map{|v| ["#{v.reg_fee}"]}
to,
f.input :reg_fee, :as => :check_boxes, :collection => RegChargeSetup.all.map{|v| "#{v.reg_fee}"}
form do |f|
f.inputs do
f.input :name, label: "Student Name"
f.input :dob,:label => "Date of Birth"
f.input :age,:label => "Age"
f.input :gender, as: :radio, :label => "Gender", :collection => [ "Male", "Female"]
f.input :reg_fee, :as => :check_boxes, :collection => RegChargeSetup.all.map{|v| "#{v.reg_fee}"}
end
f.actions
end
I have a simple form:
<%= f.input :type, :required => true, :collection => ["Nonprofit","School","Company"], :hint => "Note: nonprofits will need to provide proof of nonprofit status", :input_html => { :value => params['type'] } %>
<%= f.input :name, :label => "Organization" %>
<%= f.input :first_name %>
<%= f.input :last_name %>
<%= f.input :email %>
A user gets to this page through a url like http://www.website.com/org/signup?type=Company
I can use this format to enter a value into a field like name or email, but can't figure out how to pass the param to the drop down.
I've already tried a few things including changing :value to :selected or :option but nothing seems to work.
Alright, figured it out! Posting here for future use.
<%= f.input :type, :required => true, :collection => ["Nonprofit","School","Company"], :hint => "Note: nonprofits will need to provide proof of nonprofit status", :selected => params['type'] %>
The trick is to drop the :input_html part and just use
:selected = > params['type']
Hope that helps someone in the future!
In our rails 3.1.4 app, there are user (parent) and user_levels (child) models.
class User < ActiveRecord::Base
attr_accessible :name, :login, :password, :user_levels_attributes, :as => :role_new
has_many :user_levels
ccepts_nested_attributes_for :user_levels, :allow_destroy => true, :reject_if => proc { |a| a['position'].blank? }
validates_associated :user_levels
end
class UserLevel < ActiveRecord::Base
belongs_to :user
validates_presence_of :position
end
The position column in user_level has to be filled. If it is not, both user and user_levels should NOT be saved. The problem with the above is that it always causes error of "position can't be blank" even there is a position value in the params.
{"utf8"=>"✓",
"user"=>{"name"=>"tester ceo",
"login"=>"testceo",
"update_password_checkbox"=>"[FILTERED]",
"password"=>"[FILTERED]",
"password_confirmation"=>"[FILTERED]",
"user_levels_attributes"=>{"1339886115748"=>{"position"=>"ceo"}}},
"commit"=>"Save"}
After deleting user_levels_attribues, the model saves user into users table no matter what kind of user_levels is filled int. We did extensive online search and haven't found a solution yet. For example, if validates_presence_of :user_levels is added to the user model, then none of the user levels can be saved or updated, even with a valid position.
Any suggestion about how to implement the orchestrated saving/updating of two associated models? Thanks so much.
UPDATE:
_user_level.html.erb:
<div class="fields">
<%= f.input :position, :collection => return_position, :prompt => "Choose position",
:label => false, :include_blank => true, :selected => i_id %>
<%= link_to_remove_fields "remove", f %>
</div>
_form_new.html.erb:
<%= simple_form_for #user do |f| %>
<%= f.input :name, :label => 'name：' %>
<%= f.input :login, :label => 'login：', :hint => '6 digits ' %>
<%= f.input :password, :label => 'password：', :hint => '6digits', :input_html => {:id => 'new_user_password'} %>
<%= f.input :password_confirmation, :label => 'confirmation：' %>
<%= f.input :user_type, :label => 'user type：', :collection => return_user_type, :include_blank => true %>
position：
<p><%= link_to_add_fields "Choose position", f, :user_levels %></p>
<p><%= f.button :submit, 'Save' %></p>
<% end %>
Here is the method to add position field:
#add user position in system user creation
def link_to_add_fields(name, f, association)
new_object = f.object.class.reflect_on_association(association).klass.new
fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder|
render :partial => association.to_s, :locals => {:f => builder, :i_id => 0}
end
link_to_function(name, "add_fields(this, \"#{association}\", \"#{j fields}\")")
end
JS file:
function add_fields(link, association, content) {
var new_id = new Date().getTime();
var regexp = new RegExp("new_" + association, "g")
$(link).parent().before(content.replace(regexp, new_id));
}
I think you need to remove the :reject_if and change validates_associated :user_levels to validates_presence_of :user_levels.
In a form in active admin, the fields expand horizontally across the page according to the size of the window. If it's a big monitor, there is a lot of "unused" space to the right.
How can I add a "column" (NOT a side bar) to the right of the page so that I will end up with a 50% width section of the form on the left and a 50% width section of the form on the right?
I need this because I have lots of fields.
This is what my form partially looks like right now...
form do |f|
f.inputs "Shipment Details" do
f.input :file_number
f.input :customer, :label_method => :company_name
f.input :shipper, :label_method => :company_name
f.input :broker, :label_method => :company_name
end
f.inputs "Places" do
f.input :place_of_origin, :as => :select, :collection => Place.find(:all, :order => "city", :select => "city").map(&:city)
f.input :place_of_loading, :as => :select, :collection => Place.find(:all, :order => "city", :select => "city").map(&:city)
f.input :place_of_delivery, :as => :select, :collection => Place.find(:all, :order => "city", :select => "city").map(&:city)
f.input :via, :as => :select, :collection => Place.find(:all, :order => "city", :select => "city").map(&:city)
end
f.inputs "Carrier" do
f.input :carrier, :label_method => :company_name
f.input :mode, :as => :select,
:collection => ["Air", "Air Collect", "Air Prepaid", "FCL", "FTL", "LCL", "LTL", "TBA"]
f.input :mbl, :label => "MBL"
f.input :hbl, :label => "HQL"
f.input :vessel
f.input :container
end
f.buttons
end
It's pretty simple, you can give each section of your inputs a CSS class, then you would modify active_admin.css.scss (or just .css) so it would float your forms to the correct place, as well as give them a correct width, etc.
EDIT: looking for this: http://diminishing.org/extending-formtastic-with-a-sprinkle-of-jquery (If this works I'll answer my own question)
I've started to create an in and out type habtm (has many and belongs to many) form through formtastic. However I would like it to be more flexible to the user, meaning if you select a name on one side you either click a button that moves it right away (ajax on click) or after the form is submitted
(I'm using formtastic with this, but it doesn't have to in anyones examples)
What I am struggling with is the javascript, in and out buttons..

I'll be using jquery to fix this problem:
