Trying to extend ActionView::Helpers::FormBuilder

由 泄露秘密 提交于 2019-12-01 07:47:17
问题 I am trying to DRY up some code by moving some logic into the FormBuilder. After reading the documentation about how to select and alternative form builder the logical solution for me seemed to be something like this. In the view <% form_for @event, :builder => TestFormBuilder do |f| %> <%= f.test %> <%= f.submit 'Update' %> <% end %> and then in app/helpers/application_helper.rb module ApplicationHelper class TestFormBuilder < ActionView::Helpers::FormBuilder def test puts 'apa' end end end

How do I pass an array to fields_for in Rails?

问题 I want to use fields_for on a subset of records in an association. I have a Month model, which has_many :payments . But in my form in my view I only want to have fields_for some of those payments. For example: - fields_for @month.payments.large This doesn't work. Can I pass a set of records to fields_for , rather than the usual symbol ( fields_for :payments ) approach? 回答1: You can add additional association for large payments, for example: class Month < ActiveRecord::Base has_many :payments

I have a formbuilder form with a multiple choice list of countries.
