I am creating a system that stores cards using Ruby/Rails/HAML - In this case there is a Card class that has many Colours (this is also a class). When creating and editing a card I am using the Cocoon gem to allow me to dynamically add colour associations. The problem I am having is that in the Card model, a card is limited to having a maximum of 5 colours. Yet the interface allows adding of unlimited colours resulting in an error. Is there a way in Cocoon to limit the number of associations that can be added to a form, so that this limit is not exceeded? This is the code for a form to add

I am using the bootstrap date picker to enable selection of dates in a form using simple_form_for. For example <%= f.input :payment_date, as: :string, input_html: { class: "datepicker" } %> My date picker uses the format of dd-mm-yyyy I would like to set today's date as the default value in the form using simple_form_for, any ideas on how I can do that? juanpastas <%= f.input :payment_date, as: :string, input_html: { class: "datepicker", value: Time.now.strftime('%d-%m-%Y') } %> Another format to it is: (working with active admin gem) f.input :date, as: :date_picker, :input_html => { :value =>

I've found similar StackOverflow questions here and here but still can't get this to work. I'm using Rails 3.2.8, SimpleForm 2.0.4, and Twitter Bootstrap 2.1.1 (via the bootstrap-sass gem 2.1.1.0). The user should be able to add a contact from a modal popup window. If there are validation errors, they should appear inline, just as if the user were using a non-modal version of the form (red border around field, error message next to field). I load the modal like this: <a data-toggle="modal" data-target="#new-contact-modal">Go modal!</a> Here is the Bootstrap modal, which calls the same contacts

I am using RoR and I am using the Simple_Form gem for my forms. I have an object relation whereby a User can have multiple Roles, and during creation, the admin can select which Roles to apply to the new User. I would like the Roles to have their checkbox on the left, and their name on the right in a horizontal arrangement. // "box" Admin // instead of the current // "box" Admin // My current code to show the Roles is this. <div class="control-group"> <%= f.label 'Roles' %> <div class="controls"> <%= f.collection_check_boxes :role_ids, Role.all, :id, :name %> </div> </div> The part I am most

I have a simple_form input field that looks like this: <%= f.input :particular_users, collection: @all_users, input_html: { class: 'multiselectuser', multiple: true} %> When I leave multiple: true off, the form submits the chosen value for the parameter :particular_users and I can see the value when debugging using "raise params.inspect". However when I leave the multiple: true option there, no vales get passed for the parameter :particular_users. What am I doing wrong? EDIT: I can not use the association input because :particular_users is a virtual attribute and has no relationship. I want

I'm trying to figure out how to set the selected option of a select box generated by SimpleForm . My code is along the lines of: <%= simple_form_for(@user) do |f| %> <%= f.association :store, default: 1 %> Of course the default: 1 part does not work. TIA Use the following: selected: 1 You can now use the following: <%= f.association :store, selected: 1 %> 来源： https://stackoverflow.com/questions/10441061/how-to-set-default-selected-value-for-rails-simpleform-select-box
