simple-form

I have a normal form using simpleform. Now I'd like to add an input that does not have any corresponding field in the model, it will be processed by the controller. I tried <%= simple_form_for @obj do |f| %> <%= f.input :name %> <%= f.input :attr, as: :string %> <-- should just send "attr" as post data <% end %> but this gives a Method not found: attr_not_in_obj error. I could obviously use the standard rails helpers, but then I will miss all of the simpleform HTML around the input, and copying doesn't quite seem right. In short: I'm looking for something like simpleform version of rails tag

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

I am using simple_form gem, I have a countries collection, it work fine when I select the country, and updated record will have the country id stored, but, when I try to edit the record, the chosen country is not selected by default at edit form. Here is the code at edit form: = f.input :country_id, :collection => all_countries Shouldn't simple_form view the selected country from the db ? Have you tried to use the :selected => option? :selected => selected_country_id So, = f.input :country_id, :collection => all_countries, :selected => selected_country_id This will work perfectly !!!

I have a form that is using form_tag and not sure how to use it with the simple_form gem . This is how my form looks: <%= form_tag create_multiple_prices_path, :method => :post do %> <% @prices.each_with_index do |price, index| %> <%= fields_for "prices[#{index}]", price do |up| %> <%= render "fields", :f => up %> <% end %> <% end %> <%= submit_tag "Done" %> <% end %> Can it be done? How would a form_tag change to use simple_form correctly? What about when using it with fields_for ? A Newbie could use some help. Thank you. simple_form is a wrapper around form_for , not form_tag . You can use

I have a basketball app, where a Roster has many Players, and a Player can be on multiple Rosters.(Reason for many-to-many is for a Player-Roster archive) Roster.rb class Roster < ActiveRecord::Base belongs_to :team has_many :rosterizes has_many :players, :through => :rosterizes accepts_nested_attributes_for :players attr_accessible :jersey_number, :team_id, :class_year, :players end Rosterizes.rb (poorly named I know...) class Rosterize < ActiveRecord::Base belongs_to :player belongs_to :roster attr_accessible :player_id, :roster_id end Player.rb class Player < ActiveRecord::Base has_many

I am using simple_form in my Rails application, I tried to add form-horizontal class to my form. <form accept-charset="UTF-8" action="/account/orders" class="simple_form new_order" data-validate="true" enctype="multipart/form-data" id="new_order" method="post" novalidate="novalidate"> When I use html: { class: "form-horizontal" } it change class="simple_form new_order" to class="simple_form form-horizontal" . What should I do to keep new_order class? Vasiliy Ermolovich It's intended behaviour . So if you want to change it you should monkey-patch simple_form_css_class method in this file . it
