jquery-datatables | Jquery datatables ruby gems for assets pipeline | Application Framework library

I have created jQuery DataTables Checkboxes, now my problem is I cannot show the multiple checkboxes to select in the data table. I have tried to add a Checkboxes extension for the jQuery DataTables library that provides a universal solution for working with checkboxes in a table. But the error shows me the message is Script error Hope someone can point out which one I am getting error. Thanks.

Below is my sample coding:

I have the html table with 5 column as date which I want to convert the date format if the data is not empty.I'm using moment.js for date format.

Now date format is converted perfectly but empty column displays invalid date.So I want to check if the cell is not empty I have tried as JS fiddle

I have cloned an existing project and trying to run it in my system. Since this is the first time I don't have any Gemfile.lock file in my directory. I tried running bundle install and the following errors occur:

I'm getting error with every solution I can find, my scope is just declare a DataTables() object in my index.js. I ended up the first time initialization with the basic setup in their getting-started page: https://webpack.js.org/guides/getting-started/ After this i run npm run build and it worked. Done that, I followed the instruction on this git repo: https://gist.github.com/marcstober/c34bb4bdf7ef622cb24d6675723749bd#file-jquery-datatables-webpack I don't understand what can I have wrong, I just followed as showed in the linked resources. Just to completeness I paste my files. webpack.config.js

I have a Jquery Datatable with the datatable select addon -- https://www.gyrocode.com/projects/jquery-datatables-checkboxes/.

I am using checkbox to multi-select the row, this is the setting:

I am trying to add data based on the parent row to the child row. When I click on expand all, I want to be able to add data to the child based on the parent. When I click on the button all the rows open but the container is only added to the first row with the information of the last row on the current page of the datatable

Here is my example:

I have a button which I need to be hidden or visible based on whether any checkbox in my dataTable is checked or not,

Background: I am using simple_form to render nested attributes of an association in rails. I have applied jquery-datatables gem on the edit form for the nested association using simple_fields_for.

My model is:

This is the datatable script that creates the datatable. Checkbox target is 0, so the first column of each row is always a checkbox. That checkbox inherits an {{id}} that was sent via django views.

I want to somehow send those ids back via URL to a view, so i can see the student Ids I have seleced in datatable.

It would be really great if someone knows how to get this done in Javascript. The Ids are currently printed-> console.log(PostData) when the button is clicked. Help much apprecciated!:)
