Having trouble adding a hyperlink to a datatable

Question

I have a Django app that uses jQuery DataTables for a list view of items. Now I am trying to add a hyperlink to the first element of the table which is the primary key for the model I am displaying. The intent is for the link to take you to a detail view for the model instance. I have what I think should work but it is giving me "undefined" for each item in the datatable and throws an error when you click on it. I think it just isn't picking up the ID of the model instance.

I've tried any variation of the render function that I can think of but I'm new to javascript so I'm a bit lost. I am pretty confident that my app will work once I get this sorted out.

Here is my html:

{% extends "app/layout.html" %}
{% block content %}

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="utf-8" />
    <title>Part Requests</title>

</head>


<body>

    <h1>Part Orders</h1> 
    <a class="btn btn-info" style="float:right" href="{% url 'New_Order' %}">&nbsp; New Part Order &nbsp;</a>
    <br /><br />
    <div class="table-responsive">
        <table id="PartOrders" class="table table-hover">
            <thead>
                <tr>
                    <th>Order #</th>
                    <th>Priority</th>
                    <th>Part Number</th>
                    <th>Part Description</th>
                    <th>Quantity</th>
                    <th>Order Date</th>
                    <th>Unit Name</th>
                    <th>UIC</th>
                    <th>End Item</th>
                    <th>Reason For Order</th>
                </tr>
            </thead>
        </table> 
    </div>

and here is my models in case that helps:

class PartOrder(models.Model):
    id = models.AutoField(primary_key=True)
    Priority = models.CharField(max_length=20, choices=(('AOG','AOG'),('Rush','Rush'),('Planned','Planned')))
    PartNumber = models.CharField(max_length=35)
    PartDescription = models.CharField(max_length=200)
    SerialNumber = models.CharField(max_length=35)
    UnitOfMeasure = models.CharField(max_length=35)
    Quantity = models.PositiveIntegerField(validators=[MinValueValidator(1)])
    OrderDate = models.DateTimeField(auto_now=True)
    UnitName = models.CharField(max_length=35)
    UIC = models.CharField(max_length=6)
    ShippingAddress = models.CharField(max_length=200)
    TimeSinceNew = models.CharField(max_length=35)
    EndItem = models.CharField(max_length=20, choices=(('UH-72A','UH-72A'),('44301-10-7 Hoist','44301-10-7 Hoist')))
    AircraftSN = models.CharField(max_length=7)
    AircrafTime = models.DecimalField(max_digits=5, decimal_places=2)
    Engine1SN = models.CharField(max_length=12)
    Engine1_TSN = models.DecimalField(max_digits=5, decimal_places=2)
    Engine2SN = models.CharField(max_length=12)
    Engine2_TSN = models.DecimalField(max_digits=5, decimal_places=2)
    ReasonForOrder = models.CharField(max_length=200)
    RequestedBy = models.CharField(max_length=35)

    class Meta:
            ordering = ['Priority']

Answer 1

I think, you should refer to the first argument of render callback:

render: function (data, type, full) => `<a href="/order/${data.path}">${data.id}</a>`

Other than that, I would recommend to use DataTables option ajax rather than wrapping your code with your own $.get() success callback - it would give you more flexibility and better integration with DataTables API;
DataTables/jQuery files are normally included in <head> section of the page;
Plain table header appearing before all the necessary files are loaded may look annoying, so you may set DataTables initialization target node as simple as:

<table id="PartOrders" class="table table-hover"></table>

DataTables will populate that for you (including header, you simply need to change columns.name option for columns.title )
