I have Users who need to answer some questions upon registering. Users has_many Questions through an Answers join table. I am just trying figure out how to create the form on the Users#new action. I am using simple_form. Here is my DB Schema:
ActiveRecord::Schema.define(:version => 20120831144008) do
create_table "answers", :force => true do |t|
t.integer "user_id"
t.integer "question_id"
t.text "response"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
add_index "answers", ["user_id", "question_id"], :name => "index_answers_on_user_id_and_question_id"
create_table "questions", :force => true do |t|
t.string "title"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
create_table "users", :force => true do |t|
t.string "first_name"
t.string "last_name"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
end
So on the users#new page, I am looping through the question titles, and need to create a text area below each question and have it get created. here is what I have for a form so far, it doesn't work and probably wont help much for a solution but.
<%= simple_form_for(@user) do |f| %>
<%= f.input :first_name %>
<%= f.input :last_name %>
<%= f.input :email %>
<%= f.input :phone %>
<%= f.input :organization %>
<%= f.input :primary_contact %>
<%= f.association :answers, collection: @questions %>
<% @questions.each do |question| %>
<div>
<strong><%= question.title %></strong>
<%= text_field_tag 'questions[]' %>
</div>
<% end %>
<%= f.button :submit %>
<% end %>
Solution
I was able to get this to work, not sure if this is the absolute correct way but it's not completely ugly. In my controller I have @user.answers.build and in my simple_form I loop through questions, and create an answer field with the required data filled in.
<% Question.all.each do |question| %>
<%= f.simple_fields_for :answers do |a| %>
<div>
<strong>
<%= question.title %>
</strong>
<%= a.hidden_field :question_id, value: question.id %>
<%= a.input :response, label: false %>
</div>
<% end %>
<% end %>
