I'm building an app, where users can give comments by just leaving their email to the comment. I want them to be able to register directly from there, by a link with their email adress as a param (like: <%= link_to register_path(:email => @comment.email %> ) - so there is no existing user record yet. this should be done by applying a value to the form.input field via the :value option. But the following code doesn't work! <%- if params[:email] -%> <%= f.input :email, :required => true, :value => params[:email] %> <%- else -%> <%= f.input :email, :required => true %> <%- end -%> I had a look

I'm trying to customise a ActiveAdmin form for a Recipe model that has a has_many relationship with Step. class Recipe < ActiveRecord::Base has_many :steps end class Step < ActiveRecord::Base acts_as_list :scope => :recipe belongs_to :recipe end I have the following in my ActiveAdmin file with relation to this: form do |f| f.has_many :steps do |ing_f| ing_f.inputs end end The following error is thrown when I try to load the form: undefined method `new_record?' for nil:NilClass I've isolated it so far to the has_many method but I'm lost past this.

I'm creating a multi-part form in the style that Ryan Bates describes here: http://railscasts.com/episodes/217-multistep-forms http://asciicasts.com/episodes/217-multistep-forms (text-based version) To summarize, I have one view (with a bunch of partials for each form step), and the form variables are stored in a session when the user clicks a next button and a different part of the form is displayed. One of my form steps allows the user to upload several images via the Paperclip gem. The problem with that is that Rails is trying to upload the image data to the session, which is returning

I'm trying to build a form, with formtastic, inside an active_admin model. The problem is I need a certain script tag and other raw HTML stuff directly inside or around the form. I'm doing it with the normal form block: form do |f| f.inputs :name => "User Details", :for => :user do |user_form| user_form.input :first_name, :required => true ... How do I embed a simple div tag right in between? Or even a script tag? I thought about using a render :partial , but I want to know if the above method is possible first. Thanks! You can insert a div or javascript like this: f.form_buffers.last <<

I would like to make a dynamic select option via Activeadmin 's formtastic like so: form do |f| f.inputs "Exam Registration Details" do f.input :user_id, :as => :select, :collection => User.where(:admin => 'false') #selects user from list. WORKING f.input :student_id, :as => :select, :collection => Student.joins(lessons: :user) #collection of students will change to students who have lessons with chosen user. NOT WORKING, returns all students who have lessons. f.input :lesson_id, :as => :select, :collection => Lesson.joins(:student, :user) #collection of lessons will change to reflect lessons

using simple_form we can change class of a label using: label_html => {:class => "myclass"} but how do we do the same when dealing with checkboxes? simple_form assigns the default class of collection_check_boxes Is there a way to change this default class? I wanted to give an update to this answer in case someone comes here looking for a way to do this as I did. You can give the label a class with this option :item_wrapper_class => 'class_goes_here' Here is a full example: = user.input :resident, :collection => [["In the U.S", true],["Outside the U.S.", false]], :label_method => :first, :value
