Change Cell Color Conditional Formating Django HTML
I have a table in my HTML view that I want the cell background to change when a certain value is within the cell. Here is a screenshot of my table in HTML. The values are populated with a simple for loop within my Django views. Attached you will see the css and HTML. On the top of the table, you will see the legend. For example if the value in any td tag == 6 , make cell background rgb(1, 109, 167). That's what I'm trying to accomplish.

Html Button wrapped with anchor tags redirecting to ancor tag URL instead of button Onlick property
I have an HTML code in my Django project. I used an anchor tag to wrap a button. The anchor tag has its own href and the button also has an onclick property that when pressed will lead to a different destination. see code below <article class="card-group-item"> <header class="card-header"><h4 class="title">Links </h4></header> <div class="filter-content"> <div class="list-group list-group-flush"> <a href={{ add_drug_disposal_url }} class="list-group-item">Drug Disposal form <button class="button" onclick={{ add_drug_disposal_upload_url }}> <i class="fa fa-upload"></i> </button> </a> <a href={{ add_chain_of_custody_url }} class="list-group-item">Chain of custody <button class="button" onclick={{ add_chain_of_custody_upload_url }}> <i class="fa fa-upload"></i> </button> </a> <a href={{ add_drug_disposal_url }} class="list-group-item">Incident and Temperature Excursion Report <button class="button" onclick={{ add_incident_report_upload_url }}> <i class="fa fa-upload"></i> </button> </a> </div> <!-- list-group .// --> </div> </article> <!-- card-group-item.// --> how can I make sure that the button onclick will trigger when the button is pressed and not that of the anchor tag? note that all URLs are being picked by the template from the view just fine -

Django 4 with sqlite3 JSONField creating a "TEXT" column instead of "JSON"
I'm using Django 4 with SQLite3 database (although I will use mysql in production). I have a model such as this: class Video(models.Model): title = models.CharField(max_length=180) meta = models.JSONField(default=dict) I would expect that the column type of "meta" should be "JSON", but actually the migration creates it as a "TEXT" column and then encodes/decode the json data as a string. This is a problem because you lose JSON field capabilities (such as updating only certain keys, not updating the entire encoded string). From reading it appears that sqlite3 supports JSON field type, so how can I force Django to use it? -

Pass variable to tables2?

Hot Reload with django template and react?
Is hot reloading possible while mounting react components into our Django template?
