We already know how to use for, if-else, filter and url template tags in Django. We can also create custom template tags in Django if any requirement is not getting fulfilled with existing tags.
Here we are introducing you with 5 Django template tags which are lesser-known and used by beginner Django developers.
1. lorem
This template tag is used to insert random lorem ipsum Latin text in the template. This is useful when you want to show the sample data instead of blank space.
This tag accepts 3 optional parameters: count, method, and random.
The count is the number of words or paragraphs to produce. The method can have values w for words, p for HTML paragraphs and b for plain-text paragraphs. When the third parameter, random, is used, the text is generated randomly instead of using lorem ipsum text.
Refer to this Django template fiddle for example and demo.
2. templatetag
Double curly braces are used to display variables in Django templates. What if you want to display just curly braces in template. For this to achieve we can use templatetag template tag.
3. cycle
This tag accepts the variable number of arguments and outputs the next argument each time this tag is called. Once all arguments have been called, loop restarts from the starting.
We can use variables or string or a mix of both as arguments for this tag.
Refer to this Django template fiddle for example and demo.
<!-- mylist is {"mylist":["Line 1","Line 2","Line 3","Line 4","Line 5","Line 6"]} -->
{% for item in mylist %}
<div style="color:{% cycle 'red' 'green' 'blue' 'yellow' %}">
{{item}}
</div>
{% endfor %}
Output:
