Problems encountered when working on projects:

Each div is output by the loop variable:

{% for key,value in formextenddetail %}

{{ key }}< ;/div>

{% endfor %}

But I want two divs in one row, use

...

This look

Because I am responsible for the front-end, I am not very familiar with views. I want to control them directly in the template. After searching, I found that there is no need to directly use multiplication, division or mod calculation, which is embarrassing.

Easy to know, Django template addition:

{{ value|add:10}}

value=5, then 15 is returned. Django template subtraction:

{{value|add:-10}}

value=5, then -5 is returned. This is easier to understand. Subtraction is to add a negative number. Django template multiplication:

{% widthratio 5 1 100 %}

The above code means: 5/1 *100, returns 500, widthratio requires three parameters, it will use parameter 1/parameter 2 * parameter 3, so if you want to perform multiplication, just set parameter 2 = 1 to perform Django template division

{% widthratio 5 100 1 %}

The above code means: 5/100*1, returns 0.05, just set the third parameter to 1.

But these methods are very troublesome to use for remainder division.

Solution: divisibleby tags!

Use Django’s divisibleby tag to implement it, as follows:

{% for each in somelist %}

{% if forloop.counter|divisibleby:2 %}

{% else %}

{% endif %}

{% endfor %}

The meaning of the

divisibleby tag is to use the following parameters to remove it, and all the exceptions are True, otherwise it is False.

So, my code changed to:

{% for key,value in formextenddetail %}
{% if forloop.counter|divisibleby:'2' %}
< td style="width: 50%" >

{{ key } }

{{ value }}

{% else %}

{% endif %}
{% endfor %}

{{ key }} {{ value }}

This solution can also be used for line breaks and style changes, etc.!
