How do I increment elapsed time without refreshing the page

I need the elapsed_time to be updated every second, but it only updates when refreshing the page. I am using setTimeout in the script. I need the counter to be updated every second in the script below the following code:
shifts_controller.rb
class User::ShiftsController < ApplicationController
before_action :authenticate_user!
before_action :set_shift, only: %i[show edit update destroy]
# GET /shifts or /shifts.json
def index
#shifts = current_user.shifts.order(id: :desc)
#shift = current_user.shifts.where(clock_out: nil).where.not(clock_in: nil).first
end
# GET /shifts/1 or /shifts/1.json
def show; end
# GET /shifts/new
def new
#shift = Shift.new
end
# POST /shifts
def create
#shift = Shift.new(user: current_user) # quando criar ja liga ao id
respond_to do |format|
if #shift.save
format.html do
redirect_to action: 'index', user_id: current_user,
notice: 'Shift was successfully created.'
end
else
format.html { render :new, status: :unprocessable_entity }
end
end
end
# GET /shifts/1/edit
def edit; end
# PATCH/PUT /shifts/1
def update
#shift.set_clock_out
respond_to do |format|
if #shift.save
format.html do
redirect_to action: 'index', user_id: current_user,
notice: 'Shift was successfully updated.'
end
else
format.html { render :edit, status: :unprocessable_entity }
end
end
end
# DELETE /shifts/1 or /shifts/1.json
def destroy
#shift.destroy
respond_to do |format|
format.html do
redirect_to action: 'index', user_id: current_user,
notice: 'Shift was successfully destroyed.'
end
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_shift
#shift = Shift.find(params[:id])
end
# Only allow a list of trusted parameters through.
def shift_params
params.require(:shift).permit(:clock_in, :clock_out, :user_id, :user_name)
end
end
index.html.erb
<div class='container'>

</div>
<script>
(function timer () {
document.getElementById("time").innerHTML = "<%=elapsed_time%>";
setTimeout(timer, 1000); // recalls the function after 1000 ms
})();
</script>

Rails 6 Drag and Drop ( Sortable )

I have problem with my HTML sortable update in rails 6. I drag and drop some portfolio images through web page and that is working good but when i want to update the web page with updated position i got NoMethodError (undefined method `each' for nil:NilClass):
I use this script for HTML Sortable
https://github.com/jordanhudgens/devcamp-portfolio/blob/master/app/assets/javascripts/html.sortable.js
portfolio_controller:
class PortfoliosController < ApplicationController
before_action :set_portfolio_item, only: [:edit, :show,:update, :destroy]
layout "portfolio"
access all: [:show, :index, :angular], user: {except: [:destroy, :new, :create, :update, :edit]}, site_admin: :all
def index
#portfolio_items = Portfolio.by_position
end
def sort
params[:order].each do |key, value|
Portfolio.find(value[:id]).update(position: value[:position])
end
head :ok
end
def angular
#angular_portfolio_items = Portfolio.angular
end
def new
#portfolio_item = Portfolio.new
3.times { #portfolio_item.technologies.build }
end
def create
#portfolio_item = Portfolio.new(portfolio_params)
respond_to do |format|
if #portfolio_item.save
format.html { redirect_to portfolios_path, notice: 'Your Portfolio item is now live.' }
else
format.html { render :new }
end
end
end

end
def update
respond_to do |format|
if #portfolio_item.update(portfolio_params)

end
end

end
def portfolio_params
params.require(:portfolio).permit(:title,
:subtitle,
:body,
technologies_attributes: [:name]
)
end
end
routes.rb:
Rails.application.routes.draw do
devise_for :users, path: '', path_names: { sign_in: 'login', sign_out: 'logout', sign_up: 'register'}
resources :portfolios, except: [:show] do
put :sort, on: :collection
end
get 'angular-items', to: 'portfolios#angular'
get 'portfolio/:id', to: 'portfolios#show', as: 'portfolio_show'
get 'about-me', to: 'pages#about'
get 'contact', to: 'pages#contact'
resources :blogs do
member do
get :toggle_status
end
end
root to: 'pages#home'
end
Here is my portfolio.js :
var ready, set_position;
ready = void 0;
set_position = void 0;
set_position = function() {
$(".card").each(function(i) {
$(this).attr('data-pos', i + 1);
});
};
ready = function() {
set_position();
$('#sortable').sortable();
$('#sortable').sortable().bind('sortupdate', function(e, ui) {
var updated_order;
updated_order = [];
set_position();
$(".card").each(function(i) {
updated_order.push;
({
id: $(this).data('id'),
position: i + 1
});
});
$.ajax({
type: 'PUT',
url: '/portfolios/sort',
data: {
order: updated_order
}
});
});
};
$(document).ready(ready);
_portfolio_item.html.erb :
<div class="card" data-id="<%= portfolio_item.id %>">
<%= image_tag portfolio_item.thumb_image unless portfolio_item.thumb_image.nil? %>
<p class="card-text">
<span>
<%= link_to portfolio_item.title, portfolio_show_path(portfolio_item) %>
</span>
<%= portfolio_item.subtitle %>
</p>
</div>
Thank you for your helps!

The only place I see an each statement is in the sort method of your PortfoliosController.
params[:order].each
You need to set your params[:order] or prevent this error from happening by checking if it is set. You could use the save navigation operator:
params[:order]&.each
Or you could check if the order parameter is set with the present? method.
if params[:order].present?
params[:order]&.each

No template found for SomeController#create rendering head :no_content

I am building a rails app that creates a like(create) or unlike(destroy), on a link click with a remote: true ajax request
The Post goes through and the transaction is committed but the the js response is not going through and I receive a Error in the server console
No template found for ForumThreads::ForumPosts::LikesController#create, head :no_content
the view structure is
forum_threds/show.html.haml
....
= render #forum_thread.forum_posts
....
to render a view of every post that is in the thread
than
forum_posts/_forum_post.html.haml
....
%div{id: "fourm_post_#{forum_post.id}" }
= render partial: "forum_posts/likes", locals: { post: forum_post }
....
which is rendering
forum_posts/_likes.html.haml
- if user_signed_in? && current_user.likes?(post)
= link_to "UnLike", forum_post_likes_path(post), method: :delete,
remote: true
- else
= link_to "Like", forum_post_likes_path(post), method: :post, remote:
true
and my controller is
class ForumThreads::ForumPosts::LikesController < ApplicationController
before_action :authenticate_user!
before_action :set_forum_post
before_action :set_forum_thread
def create
#forum_post.likes.where(user_id: current_user.id).first_or_create
respond_to do |format|
format.js
format.html { redirect_to #forum_thread}
end
end
def destroy
#forum_post.likes.where(user_id: current_user.id).destroy_all
respond_to do |format|
format.js
format.html { redirect_to #forum_thread}
end
end
private
def set_forum_thread
#forum_thread = ForumThread.find(#forum_post.forum_thread_id)
end
def set_forum_post
#forum_post = ForumPost.find(params[:forum_post_id])
end
end
With remote: false this works as expected with the page reload but when i put remote: true I receive the no template error
my file structure for the views
forum_threads/
show.html.haml
forum_posts/
show.html.haml
_likes.html.haml
likes/
create.js.erb
destroy.js.erb
and the create.js.erb and destroy.js.erb
$("#forum_post_<%= forum_post.id %>").html(<%= j render
'forum_posts/likes' %>);
but i know that this file isn't even being called
is there a way from the format.js that i may be able to call the file i need directly? or something?

Update nested form attribute with a iteration

I'm currently trying to use the nested form with cocoon, is awesome !! But I'm facing to an interrogation and I don't know which way I should take.
Relations :
Ranch have Cows
Ranch have Productions
Production have nested form Iproductions
What I'm trying to do now is implement my iteration |c| into each of my iproductions:cow_id elements
My code:
(My_form production)=
<%- #cows.each do |c| %>
<div class="row">
<div class="col-md-12">
<div id="Order">
<%= f.simple_fields_for :iproductions do |ip| %>
<%= render 'iproductions_fields', f: ip, cow: c %>
<%end%>
<div class="Order_links">
<%= link_to_add_association c.name, f, :iproductions, cow: c, class: "btn btn-default" %>
</div>
</div>
</div>
</div>
(My iproductions_fields)=
<div class="form-inline clearfix">
<div class="nested-fields">
<%= f.input :cow_id, :input_html => { :cow_id => :cow } %>
<%= f.input :quantity, input_html: {class: "form-input form-control"} %>
<%= link_to_remove_association "Supprimer", f, class: "form-button btn btn-default" %>
</div>
</div>
(My productions_controllers)=
class ProductionsController < ApplicationController
before_action :authenticate_user!
skip_before_action :configure_sign_up_params
before_action :set_ranch
before_action :set_production, except: [:create, :new, :show]
before_action :set_production2, only: [:show]
# GET /productions

#productions = Production.all
end
# GET /productions/1
# GET /productions/1.json
def show
#iproductions = Iproduction.where(id: params[:production_id])
end
# GET /productions/new
def new
#production = #ranch.productions.build
#cows = #ranch.cows
end
# GET /productions/1/edit
def edit
#cows = #ranch.cows
end
# POST /productions
# POST /productions.json
def create
#production = #ranch.productions.create(production_params)
#production.update(date: Date.today)
#cows = #ranch.cows
respond_to do |format|
if #production.save
format.html { redirect_to ranch_production_path(#production.ranch_id, #production), notice: 'Production was successfully created.' }
format.json { render :show, status: :created, location: #production }
else
format.html { render :new }
format.json { render json: #production.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /productions/1
# PATCH/PUT /productions/1.json
def update
respond_to do |format|
if #production.update(production_params)
format.html { redirect_to ranch_production_path(#production.ranch_id, #production), notice: 'Production was successfully updated.' }
format.json { render :show, status: :ok, location: #production }
else
format.html { render :edit }
format.json { render json: #production.errors, status: :unprocessable_entity }
end
end
end
# DELETE /productions/1
# DELETE /productions/1.json
def destroy
#production.destroy
respond_to do |format|
format.html { redirect_to ranch_productions_path(#production.ranch_id), notice: 'Production was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_ranch
#ranch = Ranch.find(params[:ranch_id])
end
def set_production2
#production = Production.find_by(id: params[:id])
end
def set_production
#production = #ranch.productions.find_by(id: params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def production_params
params.require(:production).permit(:name, :ranch_id, :created_at, :date, iproductions_attributes: [:id, :date, :cow_id, :quantity, :_destroy])
end
end
My real view , so I would like to Assign each iproduction with the button which generate the iproductions_fields
So if you have any idea of which way I can try to achieve this goal, you're welcome,
Thanks in advance

Rails 3 - JSON of nested models not returning as expected

I'm trying to set up a javascript front in that is consuming JSON from a Rails backend.
The only problem is, when I have nested models in Rails, I'm not sure if the JSON being returned is in the correct format.
I have a Post model and a Comment model. A Post has many Comments. Each model has a 'title' and 'content' field.
Here's where my problem is so far...
1) When I visit the url: http://localhost:3000/posts.json I get the expected output:
> [{"content":"My first
> post","created_at":"2012-02-07T18:56:16Z","id":1,"title":"Hello","updated_at":"2012-02-07T18:56:16Z"},{"content":"More
> crap","created_at":"2012-02-07T21:30:51Z","id":2,"title":"My 2nd
> Post","updated_at":"2012-02-07T21:30:51Z"}]
2) If I put in this url: http://localhost:3000/posts/1/comments/4.json I also get the expected:
> {"content":"that's
> nice","created_at":"2012-02-07T20:57:16Z","id":4,"post_id":1,"title":"cool","updated_at":"2012-02-07T20:57:16Z"}
3) But... if I put in a url like this: http://localhost:3000/posts/1/comments.json
it returns null.
I don't have access to the JSON version of the list of Comments associated with the Post.
Using the standard Rails views, I can do full CRUD with the nesting no problem, but do I need to do something different from the way Rails normally passes the JSON back in order to consume it on the client side?
EDIT
I'm assuming you may need to see the controller code for the comments controller. Here it is:
class CommentsController < ApplicationController
before_filter :get_post
respond_to :html, :xml, :json
def index
#comments = #post.comments.all
respond_with (#comment)
end
def show
#comment = #post.comments.find(params[:id])
respond_with(#comment)
end
def new
#comment = #post.comments.build
respond_with(#comment)
end
def edit
#comment = #post.comments.find(params[:id])
end
def create
#comment = #post.comments.build(params[:comment])
respond_to do |format|
if #comment.save
format.html { redirect_to([#post, #comment], :notice => 'Comment was successfully created.') }
format.xml { render :xml => #comment, :status => :created, :location => #comment }
format.json { render :json => #comment, :status => :created, :location => #comment }
else
format.html { render :action => "new" }
format.xml { render :xml => #comment.errors, :status => :unprocessable_entity }
format.json { render :json => #comment.errors, :status => :unprocessable_entity }
end
end
end
def update
#comment = #post.comments.find(params[:id])
respond_to do |format|
if #comment.update_attributes(params[:comment])
format.html { redirect_to(#comment, :notice => 'Comment was successfully updated.') }
format.xml { head :ok }
format.json { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => #comment.errors, :status => :unprocessable_entity }
format.json { render :json => #comment.errors, :status => :unprocessable_entity }
end
end
end
def destroy
#comment = #post.comments.find(params[:id])
#comment.destroy
respond_to do |format|
format.html { redirect_to(post_comments_url) }
format.xml { head :ok }
format.json { head :ok }
end
end
protected
def get_post
#post = Post.find_by_id(params[:post_id])
redirect_to root_path unless #post
end
end

def index
#comments = #post.comments.all
respond_with (#comment)
end
You didn't assign to #comment.
