Get parent id in django-mptt - django

I am using django-mptt and jquery-treetable.
I am printing my objects with:
<table>
{% for node in nodes %}
<tr>
<td>{{ node }}</td>
</tr>
{% endfor %}
</table>
In jquery-treetable the <tr> element should have some attributes to identify which rows are children of which rows.
It needs to have the following setup
<table>
<tr data-tt-id="1">
<td>Parent</td>
</tr>
<tr data-tt-id="2" data-tt-parent-id="1">
<td>Child</td>
</tr>
</table>
but I can't seem to find the right template variables to identify the children correctly. I have only found node.id, node.tree_id, node.level, node.lft, and node.rght.

If your nodes are MPTTModels then you should have a 'parent' relationship to 'self'. Assuming that is the case, you should be able to get the parent id by doing:
node.parent.id

Jinja2 Repeats Table Rows When Reloading Page

I have a 'dashboard' page that comes up after a user selects a project that they'd like to inspect the details on. Some of these details are displayed in a table format. Below is a portion of the Jinja2 template:
`
{% if release_container.nreleases > 0 %}
<table class="table table-bordered">
<thead>
<tr>
<th scope="col">Name</th>
<th scope="col">Date Created</th>
<th scope="col">Status</th>
<th scope="col">Date Released</th>
</tr>
</thead>
<tbody>
{% for rh in release_container.release_history %}
<tr>
<td>{{rh.name}}</td>
<td>{{rh.creation_date}}</td>
<td>{{rh.status}}</td>
<td>{{rh.release_date}}</td>
</tr>
{% endfor %}
</tbody>
</table><!--ends table-->
{% endif %}
`
If I reload the page, or click on a link and then come back to the page, the same data will get appended. As an example, here's the HTML from a 'fresh' load, which is what I should look like after a reload as well:
`
<tbody>
<tr>
<td>v0.1</td>
<td>2022-11-10</td>
<td>False</td>
<td>2022-11-10</td>
</tr>
<tr>
<td>v0.2</td>
<td>2022-11-17</td>
<td>False</td>
<td>2022-11-17</td>
</tr>
</tbody>
`
But this is what it looks like when the page is reloaded:
`
<tbody>
<tr>
<td>v0.1</td>
<td>2022-11-10</td>
<td>False</td>
<td>2022-11-10</td>
</tr>
<tr>
<td>v0.2</td>
<td>2022-11-17</td>
<td>False</td>
<td>2022-11-17</td>
</tr>
<tr>
<td>v0.1</td>
<td>2022-11-10</td>
<td>False</td>
<td>2022-11-10</td>
</tr>
<tr>
<td>v0.2</td>
<td>2022-11-17</td>
<td>False</td>
<td>2022-11-17</td>
</tr>
</tbody>
`
What do I need to do in order to stop this from happening? I presume this is some kind of cache setting?
Thank you in advance for any assistance.
I've debugged the code by printing out the lengths of the various arrays to see if they change on reload, thinking that the data was being appended to the array, but the length remains '2', even though 4 different entries are rendered.
EDIT
A commenter asked to see the view code. At this point in time, it's a huge function that generates the containers that get passed to the template (which is just one template amongst half a dozen that gets passed), and I'll be refactoring that code shortly into more palatable bites, but hopefully the snippet below provides more context:
for release in releases:
rhistory_container = ProjectDashboardReleaseHistoryContainer()
rhistory_container.rid = release.id
rhistory_container.name = release.name
rhistory_container.creation_date = release.created
rhistory_container.status = release.is_active
release_container.release_history.append(rhistory_container)
"""
"""
return render_template('project_home.html',parent_container=parent_container,release_container=release_container,testing_container=testing_container,reqs_container=reqs_container,sw_container=sw_container,hw_container=hw_container)

How to get date input from table created using for loop in django?

So I have passed a context from views.py to my html template.
I have created a html table using 'For Loop' in the following way and also added a column with input date field.
<table class="table">
<thead style="background-color:DodgerBlue;color:White;">
<tr>
<th scope="col">Barcode</th>
<th scope="col">Owner</th>
<th scope="col">Mobile</th>
<th scope="col">Address</th>
<th scope="col">Asset Type</th>
<th scope="col">Schhedule Date</th>
<th scope="col">Approve Asset Request</th>
</tr>
</thead>
<tbody>
{% for i in deliverylist %}
<tr>
<td class="barcode">{{i.barcode}}</td>
<td class="owner">{{i.owner}}</td>
<td class="mobile">{{i.mobile}}</td>
<td class="address">{{i.address}}</td>
<td class="atype">{{i.atype}}</td>
<td class="deliverydate"><input type="date"></td>
<td><button id="schedulebutton" onclick="schedule({{forloop.counter0}})" style="background-color:#288233; color:white;" class="btn btn-indigo btn-sm m-0">Schedule Date</button></td>
</tr>
{% endfor %}
</tbody>
Now I would like to get that date element value in javascript, but its proving difficult since I am assigning a class instead of id(as multiple elements cant have same id).
I tried in the following way but its not working. The console log shows no value in that variable.
<script> //i is the iteration number passed in function call using forloop.counter0
function schedule(i){
var deldate = document.getElementsByClassName("deliverydate");
deldate2 = deldate[i].innerText;
console.log(deldate2); //log shows no value/empty
console.log(i); //log shows iteration number
</script>

Nested table rows in Vue

There has been several versions of this question, but I've found a specific scenario I can't get my head around. I have this template on a parent element:
<tbody>
<tr is="tree-item" v-for="item in children" :item="item"></tr>
</tbody>
So far so good. The child element is:
<tr v-on:click="toggle" class="{{ classes }}">
<td class="name">
{{ item.tree_item_heading }}
</td>
</tr>
<tr v-show="isLoaded" is="tree-item" v-for="item in grandChildren" :item="item"></tr>
It's a recursive form line, so if the first tree-item has children, they will render as tree-item too. Although it shows up fine, it is rendered as a Fragment Instance, hence the v-show property gets ignored.
Any idea on how to solve this?
Cheers
You could try using multiple tbody tags for your parent loop:
<tbody v-for='item in children'>
<tr is="tree-item" :item="item"></tr>
<tr v-show="isLoaded" is="tree-item" v-for="gItem in item.children" :item="gItem"></tr>
</tbody>

Display table data django

I want to display data from a table in a table; to retrieve the object I used the foreign key to retrieve the object (person depending on the project)
I have two tables: person & project.
class person (models.Model)
project =models.ForeignKey('plat_project.Project', blank=True,related_name='project')
pourcentage = models.IntegerField()
sum = models.IntegerField()
class project
...
in the views :
in the display function :
PersonneProject=PersonneProjet.objects.all(projet=project)
response['Listeperson']=PersonneProject
And the template :
{% for p in Listeperson %}
<tr>
<td style="text-align:center">{{ i }} </td>
<td style="text-align:center">{{ p.pourcentage}}% </td>
<td style="text-align:center">{{ p.sum }}€ </td>
</tr>
{% endfor %}
I have two problems:
I can not display the data on my chart
How to increment the i 1
You'll need to provide more information about your view function to fix the first problem (how and what are you returning from this function? Note also your typo in projet=project), but you get the loop counter with forloop.counter:
<td style="text-align:center">{{ forloop.counter }} </td>
(or forloop.counter0 if you want zero-based indexes).

Doctrine2 Nested Set rendering as a table with indentation

I have categories structure (using Gedmo Nested Tree extension for Doctrine2) like in the example:
https://github.com/Atlantic18/DoctrineExtensions/blob/master/doc/tree.md#tree-entity-example
The question is how to display all the tree as a table like this:
<table>
<tr>
<td>Category-1 name</td>
<td>Category-1 other data</td>
</tr>
<tr>
<td>Category-2 name</td>
<td>Category-2 other data</td>
</tr>
<tr>
<td><span class="indent">---</span>Subcategory-2-1 name</td>
<td>Subcategory-2-1 other data</td>
</tr>
<tr>
<td><span class="indent">---</span><span class="indent">---</span>Subcategory-2-1-1 name</td>
<td>Subcategory-2-1-1 other data</td>
</tr>
<tr>
<td>Category-3 name</td>
<td>Category-3 other data</td>
</tr>
</table>
Another words, I need to get the tree as a plain list with Level param in 1 query.
I found a way to get the list only as array (getNodesHierarchy), but I need to have it as a collection like if I called findAll()
Found the solution:
class CategoryRepository extends NestedTreeRepository
{
public function getTreeList()
{
return $this->getNodesHierarchyQuery()->getResult();
}
}
