如果是，则使用Django模板在HTML内进行其他操作

Question

I have a Django project that consists of many html pages.

I want to add an if else condition inside my html tag to return "None" whenever the time stamp = 0000-00-00 00:00:00 and return the time when it's not. My code is shown below, I used a tag to get the time in date format.

<td>{{ table.start_time|date:"Ymd G:i:s"}}</td>

Answer 1

I just used another tag:

<td>{{ table.start_time|date:"Ymd G:i:s"|default:"None"}}</td>

Thanks all!!

You can do this with the ifequal template tag.

{% with table.start_time|date:"Y-m-d G:i:s" as start_time %}
    {% ifequal start_time "0000-00-00 00:00:00" %}None{% else %}{{start_time}}{% endifequal %}
{% endwith %}

Answer 3

You can try:

{% with table.start_time|date:"Y-m-d G:i:s" as time_stamp %}
    {% if time_stamp != "0000-00-00 00:00:00" %}
        <td>{{ time_stamp }}</td>
    {% endif %}
{% endwith %}

There is no if-then control explanation in HTML, or whatever other programming capacities. HTML is a markup dialect. Writing computer programs isn't conceivable.

Css will permit you to pick between styles in light of classes and IDs.

You can do this sort of thing with JavaScript, yet you can keep it straightforward with CSS.
