how to achieve this Scenario:
admin to select multiple records using a checkbox and click a button to approve selected, which will change the status of the selected items to approved at once. records are like posts.
here is my code:
config/routes:
resources :time_cards do
collection do
get 'management'
put 'approve_multiple'
end
member do
get 'review'
get 'tracking'
patch 'approve_or_reject'
end
end
html:
<%= form_tag({controller: 'time_cards', action: 'approve_multiple'}, method: 'put', id: 'approve_multiple_time_card_form') do %>
<% #time_cards.each do |time_card| %>
<tr>
<% if time_card.status.downcase == 'submitted' %>
<td><%= check_box_tag "time_cards_to_approve[]", time_card.id %></td>
<% else %>
<td> </td>
<% end %>
<td><%= time_card.id %></td>
<td><%= time_card.week_of.to_date.strftime('%B %-d, %Y') %></td>
<td><%= time_card.user.name %></td>
<td><%= time_card.status %></td>
<td><%= output_hours(time_card.time_card_entries) %></td>
<td>
<%= link_to review_time_card_path(time_card) do %>
<% if time_card.status.downcase == 'submitted' %>
<i class="material-icons">edit</i>
<% end %>
<% end %>
</td>
</tr>
<% end %>
<%= submit_tag "Approve Selected", class: 'btn btn-success' %>
<% end %>
controller:
#PUT /time_cards/approve_multiple
def approve_multiple
authorize TimeCard
#time_cards.update_all({status: 'Approved'}, {id: params[:time_cards_to_approve]})
respond_to do |format|
if !#time_cards.errors
format.json { render json: { notice: 'Time cards approved successfully.'} }
format.html { redirect_to redirect_to management_time_cards_path, notice: 'Time cards approved successfully.'}
else
format.json { render json: { error: #time_cards.errors, alert: 'There was a problem approving the time card.'}}
format.html { redirect_to management_time_cards_path, alert: #time_cards.errors}
end
end
end
??? I don't no where it is wrong?
Send these ids to an action like this
Post.where(id: params[:ids]).update_all(approved: true)
params[:ids] is an array of posts' ids
update_all returns the number of the updated records
Ops, I took for granted we were talking about rails but it's never mentioned.

I would like to get all records with their usernames when signed in as Admin. For that my controller code is as below;
amol361s_controller.rb
def index
if current_user.admin
#amol361s = Amol361.all.search(params[:search]).order("created_at ASC")
#users = User.all.amol361s
else
#amol361s = current_user.amol361s.all.search(params[:search]).visible.order("created_at ASC")
end
respond_to do |format|
format.html
format.js
end
end
index.html.erb
<tbody id = "kola">
<% #users.each do |user| %>
<%= user.amol361s.each do |amol361| %>
<tr class="tr-<%= cycle('odd', 'even') %>" id='<%= "tr_#{amol361.id}" %>'>
<% if current_user && current_user.admin %>
<td class="col-1"><%= link_to amol361.date.try(:strftime,'%d/%m/%Y'), edit_amol361_path(amol361) %></td>
<% else %>
<td class="col-1"><%= amol361.date.try(:strftime,'%d/%m/%Y') %></td>
<% end %>
<td class="col-3"><%= span_with_possibly_red_color amol361.description %></td>
<td class="col-1"><%= number_with_precision(amol361.amount, :delimiter => ",", :precision => 2) %></td>
<td class="col-1 neg"><%= number_with_precision(amol361.discount, :delimiter => ",", :precision => 2) %></td>
<td class="col-1 neg"><%= number_with_precision(amol361.paid, :delimiter => ",", :precision => 2) %></td>
<% #balance += amol361.amount.to_f - amol361.discount.to_f - amol361.paid.to_f %>
<% color = #balance >= 0 ? "pos" : "neg" %>
<td class="col-1 <%= color %>"><%= number_with_precision(#balance.abs, :delimiter => ",", :precision => 0) %></td>
<td class="col-1"><%= amol361.delndel %></td>
<td class="col-1"><%= amol361.remark %></td>
<% if current_user && current_user.admin %>
<td class="col-1"><%= link_to "Hide", hide_amol361_path(amol361), method: :put, remote: true, style: "color:#bb7272;" %>
<%= link_to amol361, method: :delete, data: { confirm: "Are you sure?" }, :class => 'delete_item' do %>

Right now I am getting the error as undefined method amol361s' for # User::ActiveRecord_Relation:0x00007f5dec19d088.
So, I am trying to get the records followed by usernames, similar to how we gather records based on month.
Any suggestions are most welcome.
Thank you in advance.
From what I understand, you can simply eager load user records if the current user is admin, like this:
#amol361s = Amol361.includes(:user).search(params[:search]).order("created_at ASC")
If you do this, it will be effective to fetch the user data simply by calling association on each member of this relation, like this:
# example:
#amol361s.first.user.username # or whatever the name of username column is
I'm not sure I understood your question correctly though, cause it's a little bit unclear to me.
I want to use mass-update every operation in a single view, with a single update button. Using this following code, Rails thows this error

<% end %>
Do you have any clue/help about this problem?
Thank you in advance
Edit 1 : adding full stack trace
You need to change the f.check_box for check_box_tag, for instance:
<%= check_box_tag "operation[tag_ids][]", elem.id, operation.tags.include?(elem) %>
The problem in this scenario is that f.check_box is expecting that the value is bounded to the form which in not in this case.
use nested_form gem for this case i think it will work.

I'm very green when it comes to RoR and am having trouble trying to figure out whether my issue is caused by a problem in my model associations or whether I'm just not using the right syntax to access the data.
A user can have many budgets. Each budget is comprised of multiple detail lines. I thought there wasn't a need for the user id in budget_details since it's captured in budget and so can be inferred through the relationship between the three (maybe?!)
In the budget_details index I want to be able to include the users name; I've got it to work in the 'show' view but not the index.
I did use a scaffold to set these up, so I know there's a lot of crud there, I was just trying to do an example before moving to a new project to do it for real.
The actual error is;
NoMethodError in Budget_details#index
Showing C:/Sites/example1/app/views/budget_details/index.html.erb where line #17 raised:
undefined method `name' for nil:NilClass
I can't see why this fails but the show method works? Is is something to do with the scope? ie show is at the single instance level whereas index is at the 'all' level and so it can't find the data in Users?
Any help much appreciated

In your index.html.erb file:
<td><%= #user.name %></td>
You haven't defined #user in your index action - hence the error.
You can avoid this problem and altogether directly pulling #user in the controller for either action, if just use the association:
<td><%= budget_detail.user.name %></td>
And to avoid the performance hit for doing so (N+1), you can eager-load them in your controller using includes:
#budget_details = BudgetDetail.includes(:user).all
However, this association doesn't yet exist - you will need to add a 'has-one-through' relationship to your BudgetDetail class - the reverse of what you did for your User class.
has_one :user, :through => :budget
To summarize:
You should add a user association to BudgetDetail as 'has-one-through'.
Your controller actions should look like this:
def index
#budget_details = BudgetDetail.includes(:user).all
respond_to do |format|
format.html # index.html.erb
format.json { render json: #budget_details }
end
end
def show
#budget_detail = BudgetDetail.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: #budget_detail }
end
end
And in your views don't use #user.name rather:
<%= budget_detail.user.name %>
The error indicates that #user.name errors because #user is nil.
In your controller you currently seem to fetch:
def index
#budget_details = BudgetDetail.all
#users = User.all
end
def show
#budget_detail = BudgetDetail.find(params[:id])
#user = User.find(params[:id]) # THIS WOULD MEAN THAT A USER HAS THE SAME ID AS THE BUDGET_DETAIL
end
As the index action fetches the variables for the index template, you see that you aren't fetching any #userthere, just an #usersvariable that holds all users.
Instead, you should remove the user fetching in both actions, and fetch them in the view through the budget_detail.user association.
def index
#budget_details = BudgetDetail.all
end
def show
#budget_detail = BudgetDetail.find(params[:id])
end
show.html.erb
<p>
<b>Username:</b>
<%= #budget_detail.user.name %>
</p>
<% #budget_details.each do |budget_detail| %>
<tr>
<td><%= budget_detail.user.name %></td>
...
</tr>
<% end %>
I have successfully tried ajax saving in my sample formtastic with ajax form.
The new value is added to the database. But the the problem is in retrieving the list from the database as soon as i save via ajax.
How to do it.?
As soon as I add a new record I want my displaying list to be update. Both the option to add new record and list the data from database is in same page
This is my Index page. The controller and all other created via scaffolding
<h1>Listing samples</h1>
<table>
<tr>
<th><%=t :Name%></th>
<th></th>
<th></th>
<th></th>
</tr>
<% #samples.each do |sample| %>
<tr>
<td><%= sample.name %></td>
<td><%= link_to 'Show', sample %></td>
<td><%= link_to 'Edit', edit_sample_path(sample) %></td>
<td><%= link_to 'Destroy', sample, :method => :delete, :data => { :confirm => 'Are you sure?' } %></td>
</tr>
<% end %>
</table>
<br />
<%= link_to 'New Sample', new_sample_path %>
<br /><br /><br /><br /><br />
<%= semantic_form_for #sample1,:url => samples_path, :remote => true do |f| %>
<%= f.inputs do %>
<%= f.input :name %>
<% end %>
<%= f.actions do %>
<%= f.action :submit, :as => :input %>
<% end %>
<% end %>
When you save via ajax, you may have to change the way your controller responds, kinda like this:
def create
# stuff
respond_to do |format|
format.js
end
end
When you do this, rails would expect you to have created a file named create.js.erb, in which you can manipulate the data of your view(append new content to your table, render a whole new partial with your new object list, etc):
$('#your_list').html(
"<%= escape_javascript(render('your_table_partial')) %>"
);
Or
$('#your_list').append(
"<%= escape_javascript(render('your_item_of_the_table_partial')) %>"
);
These are just examples, i don't know your code enough to write the correct code for you, but you sure can use these as a base for your work.

I implemented destroy functionality using rjs template in rails. i got an error "XML Parsing Error: no element found" when destroy one record from database. is this right my coding?
I used the following versions ruby and rails:
Ruby version: 1.8.7
Rails Version: 2.3.8
Controller file:
def destroy
begin
#task = Task.find(params[:id])
#task.destroy
respond_to do |format|
#format.html { redirect_to(tasks_url) }
format.js
format.xml { head :ok }
end
rescue Exception => e
puts e
end
end
partial template file _task.html.erb:
<tr id="<%= dom_id(task) %>">
<td><%= task.name %></td>
<td><%= task.note %></td>
<td><%= task.priority %></td>
<td><%= link_to 'Show', task %></td>
<td><%= link_to 'Edit', edit_task_path(task) %></td>
<td>
<%= link_to 'Destroy', task, :confirm => 'Are you sure?', :method =>:delete,:remote => :true %>

</table>
<br />
<%= link_to 'New Task', new_task_path %>
destroy.js.rjs file:
page.alert('Hi')
The problem is that the xml format is getting requested from your destroy action, not the js format, and something is trying to parse the empty xml response produced by the format.xml { head :ok } line in the controller. It used to be that you could get away with the empty xml response, but it also looks like you're using unobtrusive javascript, and something somewhere in ujs tries to parse it.
One potential solution is to make a destroy.xml.builder view that produces a simple response, and change your controller action to read format.xml { render :layout => false } or something similar. You can also do some fun things with changing the data type your link is requesting, but I'd recommend avoiding that unless you really want to do something with your js response in destroy.js.rjs.
