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 %>

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.
I use the following form_for at one point in my code to display a series of topics for users to select from.
<%= form_for #user do |f| %>
<%= f.collection_check_boxes(:topic_ids, Topic.all.sample(50).each, :id, :topic_name) %>
<%= f.submit %>
<% end %>
When it renders on the page, the boxes are all one-after-the-other. How can I separate them so that there is one check box per line?
from reference here
It is possibly to customize the way the elements will be shown by giving a block to the method as sample below from your code above
<%= form_for #user do |f| %>
<%= f.collection_check_boxes :topic_ids, Topic.all.sample(50).each, :id, :topic_name do |b| %>
<%= b.label(class: "check_box") do %>
<%= b.check_box(class: "check_box") %>
<%= b.object.topic_name %></br>
<% end %>
<% end %>
<%= f.submit %>
<% end %>
You may of course render HTML inside the block:
<%= form_for #user do |f| %>
<%= f.collection_check_boxes :topic_ids, Topic.all.sample(50).each, :id, : topic_name do |b| %>
<div class="my-checkbox-wrapper">
<%= b.label(class: "foo") do %>
<%= b.object.topic_name %>
<%= b.check_box(class: "bar") ></br>
<%end%>
<%= f.submit %>
<%end%>
You can have a look at this example
It is very broad question. In short, using CSS.
For example using Bootstrap 4:
<%= form_for #user do |f| %>
<div class="form-check">
<%= f.collection_check_boxes :topic_ids, Topic.all.sample(50).each, :id, :topic_name, class: 'form-check-input' %>
</div>
<%= f.submit %>
<% end %>
We have a problem to save the values of the radio_buttons of a loop. It doesn't save in an array.
The SavedAnswer model has an has_and_belongs_to_many relation with the MultipleChoiceAnswer model.
This is my code:
<%= form_for #saved_answer do |f| %>
<% #questions.each do |question| %>
<%= collection_radio_buttons(:saved_answer, :multiple_choice_answer_ids , question.multiple_choice_answers, :id, :title) do |c| %>
<%= c.radio_button %>
<%= c.label %>
<% end %>
<% end %>
<%= f.submit "Submit" %>
<% end %>
My output is
Parameters: {"utf8"=>"✓", "authenticity_token"=>"57I9yLZMccvcb3Bn5/pw7kES0c9CUAGs33yCXoS0Urm1Yek/Baz8Hl7fO8Yl/OVZWLKsX7qrwOlqEBoXrGkcxQ==", "saved_answer"=>{ "multiple_choice_answer_ids"=>"1"}, "commit"=>"Submit"}
Thanks in advance!
You have form_for with |f| and collection with |f|.
It's not a good decision, i think. That can cause problems.
If not - write what you receive in params when trying to save.
Just use check boxes for your issue:
<%= form_for #saved_answer do |f| %>
<% #questions.each do |question| %>
<%= check_box_tag "saved_answer[multiple_choice_answer_ids][]", question.id, #saved_answer.multiple_choice_answer_ids.include?(question.id) %>
<%= question.title %>
<% end %>
<%= f.submit "Submit" %>
<% end %>
Refer: http://railscasts.com/episodes/17-habtm-checkboxes?view=asciicast
What I currently have is:
<%= f.label :attachment_uploader, 'Current Attachments:' %>
<%= f.fields_for :data_files do |attachment| %>
<% if !attachment.object.new_record? %>
<%= attachment.label :attachment_uploader, 'Delete: ' + attachment.object.attachment_uploader_url.split("/").last %>
<%= attachment.check_box :_destroy %>
<% end %>
<% end %>
However, if I don't have any attachments the label is still there. For the sake of aesthetics I'd like it to be hidden unless I have attachments.
I was thinking something akin to:
<%= f.fields_for :data_files do |attachment, index| %>
<% if index == 0 %>
<%= attachment.label :attachment_uploader, 'Current Attachments:' %>
<% end %>
#rest of code
<% end %>
But that doesn't work!
I've read about the f.options[:index] in another post, but I couldn't figure it out.
Add an unless empty? condition before fields_for. #object will be the object for which you created the form
<%= f.label :attachment_uploader, 'Current Attachments:' %>
<% unless #object.data_files.empty? %>
<%= f.fields_for :data_files do |attachment| %>
<% if !attachment.object.new_record? %>
<%= attachment.label :attachment_uploader, 'Delete: ' + attachment.object.attachment_uploader_url.split("/").last %>
<%= attachment.check_box :_destroy %>
<% end %>
<% end %>
<% end %>
How do you add a field set to a form_for method?
You can use field_set_tag. For example, using a generic 'user' object
For Rails 2.3.x
<% form_for(#user) do |f| %>
<% field_set_tag 'Name' do %>
<%= f.text_field :first_name %>
<%= f.text_field :last_name %>
<% end %>
<% end %>
And for Rails 3.0.0:
<%= form_for(#user) do |f| %>
<%= field_set_tag 'Name' do %>
<%= f.text_field :first_name %>
<%= f.text_field :last_name %>
<% end %>
<% end %>
You need to have a new object or get an existing object from your dc since it is a 'form for' and then you create a form builder f and call methods on that form builder such as the following:
<% form_for(#object) do |f| %>
<%= f.text_field :method_name %>
<% end %>
