I have a model called account which has_many :options. I want to create a form in which i can list all the options with a checkbox at the side, so the current account can select the options he/she wants inside a form so I can create the has_many relation.
This is what i have
def index
#account = current_account
#options = ['Op 1', 'Op 2', 'Op 3', 'Op 4']
end
and for the view:
<%= form_for(#account, url: options_path) do |f| %>
<% #options.each do |op| %>
<div class="checkbox">
<%= f.check_box(?????, {:multiple => true}, op, nil) %>
</div>
<% end %>
<%= f.submit class: 'btn btn-default' %>
<% end %>
This is obviously not working and I'm pretty sure this is not the right way to achieve what I want to do, so any help would be appreciated.
You could use fields_for:
<%= form_for(#account, url: options_path) do |f| %>
<%= fields_for :options do |options_form| %>
<% #options.each do |option| %>
<div class='checkbox'>
<%= options_form.label option do %>
<%= options_form.check_box option %> <%= option %>
<% end %>
</div>
<% end %>
<% end %>
<%= f.submit class: 'btn btn-default' %>
<% end %>
And in your params, you will get values like: params[:account][:options]['Op1'] with value '1' for true and '0' for false.

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 am trying to save parent as well as child object at the same time using accepts_nested_attributes_for
Code in controller's new method:
def new
#project = Project.new
#project.instances.build
end
and form looks like this:
<%= simple_form_for(#project) do |f| %>
<%= f.input :name %>
<%= link_to "Add New Instance", new_project_instance_path(#project), id: "new_link", remote: true %>
<% end %>
The route entry for this is:
resources :projects do
resources :instances
end
And the fields that need to be displayed instances/_form.html.erb:
<%= form.simple_fields_for :instances do |i| %>
<%= i.input :user_id %>
<%= i.input :password %>
<%= i.input :service_url %>
<% end %>
The issue here project_id being :nil, it is giving error:
No route matches {:action=>"new", :controller=>"instances", :project_id=>nil} missing required keys: [:project_id]
I need to somehow call <%= render 'cdd_instances/form', form: f %>, so that the fields get rendered below the Project details, how should I implement this?
I think your #project is null you have to pass like:
new_project_instance_path(project_id: (#project || ''))
In this case you are not able to pass non-persisted #project to create this link_to url.
I believe you are looking for something like: cocoon.
<%= simple_form_for #project do |f| %>
<%= f.input :name %>
<h3>Instances</h3>
<div id="instances">
<%= f.simple_fields_for :instances do |instance| %>
<%= render 'instance_fields', f: instance %>
<% end %>
<div class="links">
<%= link_to_add_association 'add instance', f, :instances %>
</div>
</div>
<%= f.submit %>
<% end %>
Cheers!
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 %>
I have a parent class Car and the /cars/show page lists all of the reviews associated with it. The reviews can be voted on. I am having some difficulty getting the :votes_count to update by JavaScript.
/votes/create.js.erb
$("#votes").html("<%= review.votes_count %>") // this does not work
/cars/show
<% #car.reviews.each do |review| %>
<p id='votes'><%= pluralize(review.votes_count, 'vote') %></p>
<% if current_user %>
<%= form_for(#vote, :remote => true) do |f| %>
<%= f.hidden_field "review_id", :value => review.id %>
<%= f.hidden_field "user_id", :value => current_user.id %>
<%= f.submit "vote" %>
<% end %>
<% end %>
<br />
<%= review.content %>
<% end %>
create.js.erb
<% #car.reviews.each do |review| %>
$("#review_<%= review.id %>").html("<%= pluralize(review.votes_count, 'vote') %>");
<% end %>
On a single page I might have a single Video and then checkboxes to add multiple dogs to it. Easy enough (as follows)...
View:
<%= check_box_tag "video[dog_ids][]", dog.id %>
Controller:
params[:video][:dog_ids] ||= []
But what I can't figure out how to do is have multiple videos, each with multiple dogs.
I currently have this:
<% #videos.each do |video| %>
<%= fields_for "item[]", video do |f| %>
<%= f.hidden_field :id, :index => nil %>
<%= f.text_field :title, :index => nil%>
<%= f.text_area :body, :index => nil %>
<% video.dogs.each do |dog| %>
<%= check_box_tag "item[][video[dog_ids][]]", dog.id %>
<% end %>
<% end %>
<% end %>
But when I do that, dogs_ids is always nil when it's submitted.
Any idea what I'm doing wrong?
Such a setup with fields_for "item[]" and f.text_field :title, :index => nil produces:
<input id="item__name" name="item[][title]" size="30" type="text" value="vid1">
This indicates that the checkbox name should be item[][dog_ids][].
A working example:
<% #videos.each do |video| %>
<%= fields_for "item[]", video do |f| %>
<%= f.text_field :title, :index => nil %>
<% video.dogs.each do |dog| %>
<%= check_box_tag "item[][dog_ids][]", dog.id %> <%= Dog.name %>
<% end %>
<br>
<% end %>
<% end %>
This produces result in params:
{"item"=> [
{"title"=>"vid1", "dog_ids"=>["1", "2"]},
{"title"=>"vid2", "dog_ids"=>["2"]},
{"title"=>"vid3", "dog_ids"=>["2", "3"]}
]}
