'undefined local variable or method' with render partial rails 5

I want to render a modal form and be able to render it on differents places; hence I want to be able to change the order_id that is required to create a new feedback on server side (I use AJAX).
However, my render partial does not work. I get the following error:
undefined local variable or method `user_order_id' for #<#<Class:0x007fec6be26af8>:0x007fec6bf1b2d8>
any Idea ?
index.html.erb
[...]
<%= render partial: 'feedback_modal', locals: {user_order_id: #user_last_order} %>
[...]
_feedback_modal.html.erb
<%= simple_form_for(#review, method: :post, url: review_path(current_user.id, user_order_id), remote: true) do |f| %>
<%= f.input :rating, collection: [1,2,3,4,5], prompt: "Rate this meal", class: "col-sm-3" %>
<%= f.label :comment, "Your comments" %>
<%= f.text_area :comment, class: "commentaire" %>
<%= f.button :submit ,"Send Feedback", class: "btn" %>
<% end %>
controller:
[...]
#user_last_oder = Order.where(user_id: current_user.id, status: nil).last.id

Issue in Form Validation - Ruby on Rails

I have included validation for my sign up page, but when I load the sign-up page
Error appears. It should show errors after clicking submit button
What i need to do?
My sign-up page
<% if !flash[:notice].blank? %>
<div class="notice">
<%= flash[:notice] %>
</div>
<% end %>
<%= form_for #user,validate: true do |f| %>
<% if !#user.valid? %>
<% if #user.errors.any? %>
<ul class="Signup_Errors">
<% for message_error in #user.errors.full_messages %>
<li>* <%= message_error %></li>
<% end %>
</ul>
<% end %>
<% end %>
<%= f.label("Name:") %>
<%= f.text_field(:user_name, class: "form-control") %></br>
<%= f.label("Email Address:") %>
<%= f.text_field(:email_id, class: "form-control") %></br>
<%= f.label("Password:") %>
<%= f.password_field(:password, class: "form-control") %></br>
<%= f.label("Confirm Password:") %>
<%= f.password_field(:password_confirmation, class: "form-control") %></br>
<%= f.submit("Register",class: "btn btn-primary") %>
<a class="btn btn-primary" style="margin-left:20px" href="/login" >Login</a>
<% end %>
My model where I have included my validations
User.rb
class User < ApplicationRecord
has_many :reviews
has_secure_password
EMAIL_REGEX = /\A[\w+\-.]+#[a-z\d\-]+(\.[a-z\d\-]+)*\.[a-z]+\z/i
validates :user_name, :presence => true, :on => :create, :uniqueness => true, :length => { :in => 3..20 }
validates :email_id, :presence => true, :on => :create, :uniqueness => true, :format => EMAIL_REGEX
validates :password, :presence => true, :on => :create, :confirmation => true #password_confirmation attr
validates :password_confirmation, :presence => true
end
Controller
def new
puts "****Inside New Method******"
#user = User.new
end
def create
puts "****Inside create Method******"
#user = User.new(user_params)
puts #user.user_name
if #user.save
puts "** USER DETAILS SAVED SUCCESSFULLY****"
flash[:notice] = "Registration successful, please login"
flash[:color] = "valid";
redirect_to "/login"
else
flash[:notice] = "Invalid Form"
flash[:color] = "invalid"
end
end
When I load the page, Error appears before clicking the submit button
I have included :on => :create but it doesn't work
please help!!

if !#user.valid? on the form might be causing this. This is not necesarry, since you are only checking if the record is valid in the controller, just before saving your record.
You should also add render :new when the record could not be saved, otherwise you get a view missing error.

Open rails console and try to manually create the user. Is it create or not?
eg:
user = User.new(username: "test", email_id: "test#test.com", password: ...)
and check the validation by using
user.valid!
you will get the error message if validation fails. If no error then save it
user.save!

Getting the individual checkbox value in JQuery

I have several checkboxes and have a JQuery function that I want to print out the value I give each checkbox when I click on the checkbox. However, 1 keeps printing out. I assign each checkbox an item.id based on a primary key from my db using Rails. Here is my code
<script>
$(document).ready(function(){
$('input[type="checkbox"]').on("change", function() {
var hall_id = $(this).val(); // here is where I want to get the value that I assigned to the checkbox
if (this.checked) {
console.log( hall_id );
} else {
console.log( hall_id );
}
});
});
</script>
<%= link_to "Logout", root_path %>
<h1>Hello <%= #user.first_name%> <%= #user.last_name%></h1>
<%= form_for #item do |f| %>
<%= f.label :to_do %>:
<%= f.text_field :to_do %><br />
<%= f.hidden_field :email, :value => #user.email%>
<%= f.submit %>
<% end %>
<% #items.each do |item|%>
<%if item.email == #user.email%>
<%= form_for #item do |f| %>
<%= item.id%>
<%= f.check_box :to_do, :value => item.id%> //This is where I assign the value for the check box
<%= item.to_do%><br />
<% end %>
<%end%>
<%end%>
In the image I am trying to print out the number by the checkbox(item.id), but in the console it only prints out 1

Look at the documentation on the check_box helper method: http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-check_box
Notice that the optional 4th argument is the checked_value which defaults to 1. Here is how you can switch it to the id of your item object:
<%= f.check_box :to_do, :id, {}, item.id %>

Hidden text field to be set to other Text Field value

I have the following form in rails:
<%= form_for :key, :url => delete_keys_path,:html => { :method => :get } do |f| %>
<%= f.label :key_value %>
<%= f.text_field :key_value %>
<%= button_to 'Delete', :class => 'btn',
method: :delete,
data: { confirm: 'Are you sure?' } %>
<% end %>
<%= form_for :key ,:url => unblock_keys_path,:html => { :method => :get } do |f| %>
<%= f.hidden_field :key_value %>
<%= button_to 'Unblock', :class => 'btn',
method: :get %>
<% end %>
<%= form_for :key, url: keep_alive_keys_path, :html => { :method => :get } do |f| %>
<%= f.hidden_field :key_value %>
<%= button_to 'Keep Alive', :class => 'btn',
method: :get %>
<% end %>
I want the user to input a key value and choose specific action based on which button he clicks. Since only one input is needed I set up one text field and other hidden fields
The hidden field must be set equal to value in text field on submit. I know i will have to use JavaScript but how do I do it?

Assign an id to the text field, say "textField", and to the hidden field as well, say "hiddenField".
Now using javascript,
var textFieldElement = document.getElementById("textField");
var hiddenFieldElement = document.getElementById("hiddenField");
var text = textFieldElement.value;
hiddenFieldElement.value = text;

Routing error that appears to have something to do with partials and/or forms

In a Rails 3 application, I have a "table" partial that contains a data entry form table, plus a separate smaller form (mostly hidden fields) below it to clear the table data. I have a third form underneath the partial to add a new column to the table contained in the partial. The page loads fine. The small form to clear the table data works, and refreshes the partial as it is supposed to. BUT, When I submit the add-new-column form, I get this routing error:
ActionView::Template::Error (No route matches {:controller=>"outcome_results", :action=>"clear_table"}):
70: </table>
71: <%= submit_tag "Save" %>
72: <% end %>
73: <%= form_tag url_for(:controller => 'outcome_results', :action => 'clear_table'), :id => "clear_data_table_link", :remote => true do %>
74: <%= hidden_field_tag "subgroup_id", subgroup_id %>
75: <%= hidden_field_tag "outcome_id", #selected_outcome_object.id %>
76: <%= hidden_field_tag "timepoint_id", timepoint_id %>
app/views/outcome_results/_table.html.erb:73:in `_app_views_outcome_results__table_html_erb__204353865_18893424_435027370'
app/controllers/outcome_columns_controller.rb:36:in `block (3 levels) in create'
app/controllers/outcome_columns_controller.rb:35:in `block (2 levels) in create'
app/controllers/outcome_columns_controller.rb:33:in `create'
Line 72 is the end tag of the first (table/data entry) form.
Line 73 is the form tag for my clear-table-data form which works fine on its own - no routing errors there.
My routes.rb is crazy long but contains this line:
match 'projects/:project_id/studies/:study_id/clear_table' => 'outcome_results#clear_table'
The add-new-column form looks like this:
<div id="outcome_column_validation_message"></div>
<%= form_for #outcome_column, :action => :create, :remote => true, :id=>"outcome_columns_form" do |f| %>
<%= hidden_field_tag "outcome_id", !#selected_outcome_object.nil? ? #selected_outcome_object.id : nil %>
<%= hidden_field_tag "subgroup_id", !#selected_timepoint.nil? ? #selected_timepoint : 0 %>
<%= hidden_field_tag "timepoint_id", !#selected_subgroup.nil? ? #selected_subgroup : 0 %>
<div class="field">
Custom Column Title: <%= f.text_field :name %> Description: <%= f.text_field :description %> <%= f.submit "Add Custom Column" %>
<% end %>
and the format section of the "create" action in the "outcome_column" controller looks like this:
respond_to do |format|
format.js {
render :update do |page|
page.replace_html 'outcome_results_table', :partial => 'outcome_results/table'
page['outcome_columns_form'].reset
page.replace_html 'outcome_column_validation_message', ""
end
}
end
I can post more code if it would help... anyone have any ideas about this routing error?
Thanks in advance.

The route would take two arguments: a project_id and a study_id. This is not matching the route because you have not passed through these two parameters to the url_for in your form_tag.
