Hello guys I'm working on a project with Nodejs, Handlebars and Mysql and i want to ask something. I have 2 routes, /page1 and /page2. In /page1 im doing UPDATE and SELECT queries. One of table's column i want it to redirect to /page2 in a label without refresing, is it possible to do that?
Page 1 is 'home'

I'm creating a Accounting Web System using Nodejs and Express with Handlebars (.hbs), while using Bootstrap as my main Frontend toolkit. I have a dynamic table with each row consisting of information and three buttons. With delete button ("eliminar"), I'm adding a modal to verify that the user actually wants to delete information instead of by accident.
However, when inserting the modal into my handlebar, the information no longer belongs to its appropriate row but rather the first row from the query object rendered into the handlebar. My code looks like this:
<table class="table table-bordered">
<thead class="thead-dark text-center">
<tr>
<th scope="col">Tipo ID</th>
<th scope="col">Tipo Codigo</th>
<th scope="col">Tipo Descripcion</th>
<th scope="col">Acciones</th>
<th scope="col">Usuario</th>
{{!-- <th scope="col">Tiempo Creado:</th> --}}
</tr>
</thead>
<tbody class="text-center">
{{#each tipoparametro}}
<tr>
<th scope="row">{{this.tipoparid}}</th>
<td>{{this.tipoparcodigo}}</td>
<td>{{this.tipodescripcion}}</td>
<td class="text-center">
<a href="/viewuser/{{this.tipoparid}}" type="button" class="btn btn-outline-info btn-small"><i
class="bi bi-eye"></i>Ver</a>
<a href="/edituser/{{this.tipoparid}}" type="button" class="btn btn-outline-primary btn-small"><i
class="bi bi-pencil"></i>Modificar</a>
<a href="/delete/{{this.tipoparid}}" type="button" class="btn btn-outline-danger btn-small"
value={{this.tipoparid}} data-bs-toggle="modal" data-bs-target="#staticBackdrop"
data-target={{this.tipoparid}}><i class="bi bi-person-x"></i>Eliminar - {{this.tipoparid}}</a>
</td>
{{!-- New --}}
<!-- Modal -->
<div class="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1"
aria-labelledby="staticBackdropLabel" aria-hidden="true" value={{this.tipoparid}}>
<div class="modal-dialog text-center">

</div>
</div>

</tr>
{{/each}}
</tbody>
</table>
Is there a simplified way to pass the unique identifier this.tipoparid into the modal so I can obtain the correct info from each row and not from the first all the time?
It's important for me to output the information inside the modal according to its row.
I am not exactly sure what the issue is but I have this code in my project that once I select a date it will bring up a table with the name of students in my classroom but Django keeps telling me that there isnt NoReverseMatch. i have double check and everything is fine but not sure why it not working.

class.pk is not defined so it tries to call url with 0 arguments while it needs only one.
Using Bootstrap 4 I can create a list of list-items. Each list-item contains a text and a button with an icon. The icon is taken from Fontello.
On mobile screens (XS media) sometimes the button does not take the icon as button-content. The result is a very small button that does not contain the icon. This looks like on a mobile device:
On Chrome on my Desktop (F12, XS device) the result is as expected.
A diagnosis is: When I add a number of rows, then vertical size of the list-item gets smaller. Adding 10 items, and the list-item is just a few mm high! So, the size of the list-item gets less high, the button gets less high. Has this to do with 'flexbox'?
Why is this so? I know that when you omit to put anything (or any text) in the button, the button will remain very small. How to repair this?
The code for the button (inside Angular 6)
<ul class="list-group" id="cachesOnHikeList">
<li class="list-group-item d-flex flex-row" *ngFor="let cacheonhike of cachesonhike">
<div class="flex-grow-1">{{ cacheonhike.name| slice:0:22 }}</div>
<button type="button" class="btn btn-warning btn-sm" (click)="removeGeocache( cacheonhike.gcid)"><i class="icon-cancel-circled"></i></button>
</li>
</ul>
The 'cachesOnHikeList' CSS class is:
#cachesOnHikeList {
/*max-height: 250px;*/
max-height:35vh;
overflow:auto;
overflow-y:scroll;
}
Plan-B does not work either. This code (with 2 characters added as button text) produces the same results:
<button type="button" class="btn btn-warning btn-sm px-1"
(click)="removeGeocache( cacheonhike.gcid)"> <i class="icon-cancel-circled"></i> </button>
Plan-C: Adding a 'real' character as button text does not help. The 'X' is shown below the small button. The button is similar to the ones on the screenshot.
<button type="button" class="btn btn-warning btn-sm px-1 font-weight-bold"
(click)="removeGeocache( cacheonhike.gcid)">X</button>
The problem of the small buttons may be caused by (my/the) use of flexbox in combination with a scrollable list-groups
Solution 1:
Replace the flexbox solution with the BS4 grid.
<ul class="list-group" id="cachesOnHikeList">
<li class="list-group-item" *ngFor="let cacheonhike of cachesonhike">
<div class="row">
<div class="mr-auto">{{ cacheonhike.naam | slice:0:22 }}</div>
<button type="button" class="btn btn-warning btn-sm font-weight-bold col-2 col-sm-1 px-1" (click)="removeGeocache( cacheonhike.gcid)">X</button>
</div>
</li>
</ul>
Solution 2: responsive BS4 table
Using a Bootstrap 4 table that is Responsive. In this case the width of the columns is determine automatically by Bootstrap.
<div class="row mt-2">
<div class="listMaxEntries">
<div class="table-responsive">
<table class="table table-bordered">
<thead>
<tr>
<th>GcId</th>
<th>Naam</th>
<th class="d-none d-sm-table-cell">Type</th>
<th class="d-none d-md-table-cell">Actief</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let geocache of geocachesPage.geocaches"
(click)="saveGeocacheInApplicationDataAndEditIt( geocache)">
<td>{{ geocache.gcid | slice:0:9 }}</td>
<td>{{ geocache.naam }}</td>
<td class="d-none d-sm-table-cell">{{ geocache.type }}</td>
<td class="d-none d-md-table-cell">{{ geocache.actief }}</td>
</tr>
</tbody>
</table>
</div>
</div>
</div>
Solution 3: BS4 table with Flexbox.
Using this solution you can specify the column widths. In this case the row height is good!
<div class="row mt-2">
<div class="listMaxEntries">
<table id="productSizes" class="table">
<thead>
<tr class="d-flex">
<th class="col-3 col-md-2">GcId</th>
<th class="col-9 col-sm-7 col-md-5">Name</th>
<th class="col-sm-3 d-none d-sm-table-cell">Type</th>
<th class="col-md-2 d-none d-md-table-cell">Actief</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let geocache of geocachesPage.geocaches" class="d-flex"
(click)="saveGeocacheInApplicationDataAndEditIt( geocache)">
<td class="col-3 col-md-2">{{ geocache.gcid | slice:0:9 }}</td>
<td class="col-9 col-sm-7 col-md-5">{{ geocache.naam }}</td>
<td class="col-sm-3 d-none d-sm-table-cell">{{ geocache.type }}</td>
<td class="col-md-2 d-none d-md-table-cell">{{ geocache.actief }}</td>
</tr>
</tbody>
</table>

Enjoy Bootstrap 4 -- what a very nice package!
Here am trying to append a dependent drop down based on value drop down (you can see in my HTML code for value drop down).I have wrote a onchage method to get appear dependent dropdown in html.Here i have dependent drop down for only three(i.e, Services Performed, Products Sold, Gross Retail) selected values of my values dropdown. Now am getting the dependent dropdowns, but when i have change the another drop down i.e, 2nd or 3rd ...etc dropdown ,then the previous drop down is getting disappear and latest changed dropdown value is getting appear.
so, please help me to solve it.
