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

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

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
I keep receving an error on my home page saying
'undefined method `company' for nil:NilClass'
for the first line of the following code displayed below. I am not really sure on how to fix this. I have two Controllers for both companies and customers because I am creating a two-sided marketplace.
When the user clicks the logo at the top instead of being redirected to the welcome page, the login page is being rendered since the home page is the root_path but I am using devise for before_action authenticate is being used.
<% if((current_user.company) || (current_user.customer)) %>
<%= render 'pages/welcome' %>
<% else %>
<% if current_user.is_company %>
<%= render 'companies/form', company: #company%>
<% else %>
Here is the home.html.erb file with the code which is the root_path
<% if((current_user.company) || (current_user.customer)) %>
<%= render 'pages/welcome' %>
<% else %>
<% if current_user.is_company %>
<%= render 'companies/form', company: #company%>
<% else %>
<%= render 'customers/form', customer: #customer%>
<% end %>
<% end %>
Here is my companiesController

end
it just says that the current_user is nil, you need to make sure that the user is logged in to use current_user.company
The log is giving you details as to why the company is returning a nil. The company requires an object in it for the page to load properly. But that is not so because no user is logged in for the company to have an object to return.
<% if((current_user.company) || (current_user.customer)) %> <%=
render 'pages/welcome' %> <% else %>
<% if current_user.is_company %> <%= render 'companies/form',
company: #company%> <% else %>
is returning a nil because no user is logged in.
You can first check if there is a user logged in and then render
something before this to prevent the error page
<% if(current_user) <% if((current_user.company) ||
(current_user.customer)) %>
<%= render 'pages/welcome' %> <% else %>
<% if current_user.is_company %>
<%= render 'companies/form', company: #company%> <% end %> <% else %> render something here <% end %>
Or simply log in to make sure this does not return a nil. But the first fix is the most ideal.
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:

<%= link_to_add_association c.name, f, :iproductions, cow: c, class: "btn btn-default" %>
</div>
</div>
</div>
</div>

<div class="form-inline clearfix">
<div class="nested-fields">
<%= f.input :cow_id, :input_html => { :cow_id => :cow } %>

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
I am trying to use cocoon gem to build nested forms.
I have models for Organisation, Package::Bip and Tenor.
The associations are:
Organisation
has_many :bips, as: :ipable, class_name: Package::Bip
accepts_nested_attributes_for :bips, reject_if: :all_blank, allow_destroy: true
Package::Bip (polymorphic)
belongs_to :ipable, :polymorphic => true, optional: true, inverse_of: :bip
has_one :tenor, as: :tenor
accepts_nested_attributes_for :tenor, reject_if: :all_blank, allow_destroy: true
Tenor (polymorphic)
belongs_to :tenorable, :polymorphic => true, optional: true
The forms have:
In my organisations/_form.html.erb, I have:
<%= f.simple_fields_for :bips do |f| %>
<%= f.error_notification %>
<%= render 'package/bips/bip_fields', f: f %>
<% end %>
<%= link_to_add_association 'Add another intellectual property resource', f, :bips, partial: 'package/bips/bip_fields' %>
In my bip_fields.html.erb nested form, I have:
<%# if #package_bips.tenor.blank? %>
<%= link_to_add_association 'Add timing', f, :tenor, partial: 'tenors/tenor_fields' %>
<%# end %>
<%= f.simple_fields_for :tenor do |tenor_form| %>
<%= f.error_notification %>
<%= render 'tenors/tenor_fields', f: tenor_form %>
<% end %>
Javascript
The cocoon docs suggest adding a js file to specify association-insertion-node as a function. In my tenor_subform.js I have:
$(document).ready(function() {
$(".add_tenor a").
data("association-insertion-method", 'append').
data("association-insertion-node", function(link){
return link.closest('.row').next('.row').find('.tenor_form')
});
});
Controllers
In my organisation controller, I have:
def new
#organisation = Organisation.new
#organisation.bips
end
Note: I'm not sure if I need to add another line to my new action to create the organisation.bip.tenor instance. I'm also unsure if im supposed to add has_one through association on the organisation.rb that references the tenor.
def organisation_params
params.fetch(:organisation, {}).permit(:title, :comment,
bips_attributes: [:id, :status, :_destroy,
tenor_attributes: [:id,:commencement, :expiry, :_destroy]
],
In my tenor controller, I have:
def tenor_params
params.require(:tenor).permit( :commencement, :expiry)
end
ERRORS
I am not sure if I need to add tenor actions to the organisation controller (the ultimate parent of bip which in turn is the parent of tenor).
When I save all of this and try it, I get an error that says:
unknown attribute 'tenor_id' for Tenor.
When I see other SO posts with this error, its often because the :id attribute hasn't been whitelisted in the parent class. I have done that.
Can anyone see what I've done wrong?
Tenor controller
class TenorsController < ApplicationController
before_action :set_tenor, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!
# after_action :verify_authorized
def index
#tenors = Tenor.all
# authorize #tenors
end
def show
end
def new
#tenor = Tenor.new
# authorize #tenor
end
def edit
end
def create
#tenor = Tenor.new(tenor_params)
# authorize #tenor
respond_to do |format|
if #tenor.save
format.html { redirect_to #tenor }
format.json { render :show, status: :created, location: #tenor }
else
format.html { render :new }
format.json { render json: #tenor.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if #tenor.update(tenor_params)
format.html { redirect_to #tenor }
format.json { render :show, status: :ok, location: #tenor }
else
format.html { render :edit }
format.json { render json: #tenor.errors, status: :unprocessable_entity }
end
end
end
def destroy
#tenor.destroy
respond_to do |format|
format.html { redirect_to action: :index }
format.json { head :no_content }
end
end
private
def set_tenor
#tenor = Tenor.find(params[:id])
# authorize #tenor
end
def tenor_params
params.require(:tenor).permit(:express_interest, :commencement, :expiry, :enduring, :repeat, :frequency)
end
end
You has_one relation is wrongly declared. Because you say as: :tenor makes it look for a tenor_id.
You have to declare it as follows:
has_one :tenor, as: :tenorable
Your model does not see the id of nested_attr.Add :inverse_of => #{model}.
Example:
class Tenor < ActiveRecord::Base
has_many :traps, :inverse_of => :bips
end
For more information look this or this documentation.
I'm new in rails and I'm trying to build a web app, but I encounter the limits of my abilities.
I have a classic app with user who have posts, and to put this post in public, I create a model and a controller Online.
That I'm trying to do now, It's to change the boolean :push(from Online) in false if a new Online is created with the same post_id as before.
So if I push again my post 2, the previews Online associated with the post 2 will update their :push in false.
Well, if you have any ideas about that, let me know !
Thanks

Thanks for your times !!
You probably would put it into the controller action where you can use
YourModel.where(post_id: params[:post_id]).update_all(push: false)
or something similar. It kind of depends what you want to do if you create more than 2 items with the same post_id
