rails: fields_for and collection - ruby-on-rails

i would like to use an additional collection for a fields_for. this collection should hold all the possibilities to be used in fields_for.
Lets say I have a person with tasks that will happen regularly each week on the same day. In the person form, i should have an entry for each day, even if there are not yet any saved tasks. I tried:
<% form_for(#person) do |f| %>
...
<% f.fields_for :tasks, #weekdays do |task_fields| %>
<%= weekday.name %>:
<%= project_fields.text_field :name %>
<% end %>
<% end %>
now there should be for each weekday a text field to enter the name of the task of that day. for example weekday.name = "monday" and task.name = "drinking coffee", task.weekday_id = 1

You are not iterating through the week_days. You should do like this:
<% #weekdays.each_with_index do |weekday, i| %>
<% f.fields_for :tasks do |task_fields| %>
<%= weekday.name %>:
<%= task_fields.text_field :name %>
<%= task_fields.hidden_field :weekday_id, :value => (i + 1) %>
<% end %>
<% end %>
If you have a table 'weekdays', then hidden_field value should be weekday.id
Edit: July 30
I think I completely messed up this answer. Let me try to improve it.
<% f.fields_for :tasks, #weekdays do |task_fields| %>
<%= weekday = task_fields.object %>
<%= weekday.name %>:
<%= task_fields.text_field :name %>
<%= task_fields.hidden_field :weekday_id, :value => weekday.id %>
<% end %>

Save Question(s) form with one submit button

In my rails app I have a questions view that renders all the questions in a poll. I want to make sure that all the questions rendered can be submitted using 1 submit button.
If that's not possible, how can I render one question after another until there are no more quesitons?
The front-end code goes:
poll_question.html.erb:
<% #poll.questions.each do |qst| %>
<%= render "questions" , qst: qst%>
<p style="color: red"><%= notice %></p>
<hr>
<% end %>
Render partial _questions.html.erb:
<%= form_with model: qst.question_results.build, url: question_question_results_path(qst) do |f| %>
<% qst_type = qst.poll.voting_type %>
<% option_length = qst.options.count %>
<%= f.hidden_field :question_id, value: qst.id %>
<%= f.hidden_field :option_id, value: qst.options.first.id %>
<h3> <%= qst.title %></h3>
<h6> <%= qst.description %> </h6>
<ul>
<% qst.options.each do |option| %>
<%= f.fields_for :question_result_ranks, f.object.question_result_ranks.build do |rank_f| %>
<%= rank_f.hidden_field :option_id, value: option.id %>
<%= option.title %>
<%= rank_f.select :rank, options_for_select((1..option_length).step(1)) %><br>
<% end %>
<% end %>
</ul>
<div>
<%= f.submit "Save Answer" %>
</div>
<% end %>
Here is my routes.rb
resources :users do
resources :polls
# Questions
resources :questions, shallow: true do
resources :options
resources :question_results
patch "/create_question_results", to: "questions#create_question_results", as: "create_question_results"
end
end
Edit: These views are not rendered under the Poll and Question Controller, They are rendered under the session module which has no relationships in the model.
If you want to submit all the questions with one click, you should use a nested form.
Main template poll_question.html.erb:
<%= form_with model: #poll do |form| %>
<%= form.fields_for :questions do |f| %>
# This block renders a collection of partials.
<%= render 'question', f: %>
<% end %>
<%= form.submit 'Save' %>
<% end %>
Question form _quiestion.html.erb:
<% qst = f.object %>
<% qst_type = qst.poll.voting_type %>
<% option_length = qst.options.count %>
<%= f.hidden_field :question_id, value: qst.id %>
<%= f.hidden_field :option_id, value: qst.options.first.id %>
<h3> <%= qst.title %></h3>
<h6> <%= qst.description %> </h6>
<ul>
<% qst.options.each do |option| %>
<%= f.fields_for :question_result_ranks, f.object.question_result_ranks.build do |rank_f| %>
<%= rank_f.hidden_field :option_id, value: option.id %>
<%= option.title %>
<%= rank_f.select :rank, options_for_select((1..option_length).step(1)) %><br>
<% end %>
<% end %>
</ul>
And don't forget to add accepts_nested_attributes_for :questions in your poll model.

rails: how to update multiple records using "accepts_nested_attributes"

Let's say I have a cat model and a life model. And let's say a cat (#cat) has_many lives, and a cat accepts_nested_attributes for a life.
Now, if I wanted to update 7 lives (#lives) at once, using one form_for(#cat), how would that form look like? This is what I've tried, but in this form only the attributes for the last life are passed to the params hash:
<%= form_for(#cat) do |f| %>
<% #lives.each do |life| %>
<%= f.fields_for(life) do |l| %>
<%= l.input :date_of_birth, as: :date %>
<% end %>
<% end %>
<%= f.submit %>
<% end %>
You need to build the attributes in your controller
#cat = Cat.find(<criteria>)
#cat.lives.build
In your example, you have a loop inside a loop. Try this:
<%= form_for(#cat) do |f| %>
<%= f.fields_for(:lives) do |l| %>
<%= l.input :date_of_birth, as: :date %>
<% end %>
<%= f.submit %>
<% end %>

fields_for not nesting attributes

I have this form:
<%= form_for(:quiz_responses, url: quiz_responses_path) do |f| %>
<%= f.hidden_field :name, value: #survey.name %>
<%= fields_for :questions do |ff| %>
<% #questions.each do |question| %>
<ul>
<%= ff.hidden_field "#{question_counter}", value: question.content %>
<%= ff.label question.content %>
<%= fields_for :answers do |fff| %>
<% question.answers.each do |answer| %>
<%= fff.hidden_field "#{answer_counter}", value: answer.content %>
<% answer_counter += 1 %>
<%= fff.label answer.content %>
<%= f.radio_button("user_answer[#{user_answer_counter}]", answer.content) %>
<% end #questions.answers.each do %>
<% end #fields_for answers %>
<% user_answer_counter += 1 %>
</ul>
<% question_counter += 1 %>
<% end ##questions.each do %>
<% end #fields_for questions %>
<%= f.submit %>
<% end #form_for%>
My wanted result is that I get a params hash with :quiz_responses containing a :questions hash, and each question value inside that hash contains an :answers hash containing answers. But this is what I see:
where there's a questions hash containing all the questions and a separate answers hash containing all the answers, and somehow user_answeris inside quiz_responses. How do I fix this mess?
You need to call fields_for on your form object like this:
<%= form_for(:quiz_responses, url: quiz_responses_path) do |f| %>
# ...
<%= f.fields_for :questions do |ff| %>
# ...
<%= ff.fields_for :answers do |fff| %>
# ...

Using form_for with Awesome Nested Set

I have a Comment model with the acts_as_nested_set enabled, but when I try to do something like this (for nested comments), i receive the error "comment_comments_path not found", presumably because the default pathing doesn't work with Awesome Nested Set. How do I get around this?
<%= form_for([#comment, #comment.children.build]) do |f| %>
<%= f.text_area :content, :placeholder=>'What do you think?'%>
<%= f.submit 'Submit Reply'%>
<% end %>
I also tried this:
<%= form_for(#comment) do |f| %>
<% #comment.children.each do |sub| %>
<%= f.fields_for :children, sub do |child| %>
<%= child.text_area :content, :placeholder=>'What do you think?'%>
<%= f.submit 'Submit Reply'%>
<% end %>
<% end %>
<% end %>
but it didn't generate a textbox for me to type in.
You're very close, yeah you have to build it first then have fields for, so this:
<% #comment.children.build %>
<%= form_for([#comment]) do |f| %>
<%= f.fields_for :children do |child| %>
<%= child.text_area :content, :placeholder=>'What do you think?'%>
<% end %>
<%= f.submit 'Submit Reply'%>
<% end %>
<% end %>
This will have a form for all existing children + the new one. If you want only a form for a new child then you'll want this instead:
<%= form_for([#comment]) do |f| %>
<%= f.fields_for #comment.children.build, :children do |child| %>
<%= child.text_area :content, :placeholder=>'What do you think?'%>
<% end %>
<%= f.submit 'Submit Reply'%>
<% end %>
<% end %>

A different label for each iteration

in the following code, I want to assign a different label to the text field for each iteration.
<%= f.field_for :skills do |s| %>
<li>
<label>Skills</label>
<%= s.text_field :name %>
</li>
<% end %>
How can I do that?
Here is my controller code, where I create three different skill objects:
def edit
3.times{resource.skills.build}
render_with_scope :edit
end
You could do something like this:
<% counter = 0 %>
<%= f.fields_for :skills do |s| %>
<li>
<%= s.label :name, "Skill #{counter}" %>
<%= s.text_field :name %>
<% counter = counter + 1 %>
</li>
<% end %>
It is preferred to use s.label :name, since that will make sure when you click the label, the text-box will get the focus. But the value of the label can be overruled, as i did here.
I am not quite sure what else you could mean with changing the label for each item, so if you could make that clearer.
Hope this helps.
Just scope the label to s:
<%= f.field_for :skills do |s| %>
<li>
<%= s.label :name, 'Skills' %>
<%= s.text_field :name %>
</li>
<% end %>
I think that should do it.
