15. Let us understand what we wrote in edit_contact.html in django project

 edit_contact.html

===================

<h1>add contact</h1>
<form action="{% url 'contacts-new' %}" method="post">
  {% csrf_token %}

  <ul>
  {{ form.as_ul }}

  </ul>
<input id='save_contact' type="submit" value="save"/>

    
</form>
<a href="{% url 'contacts-list' %}">back to list</a>

 so let us see what we wrote here 

<h1>add contact</h1>
====================

this is heading tag no special if we now the html tags

 
<form action="{% url 'contacts-new' %}" method="post">

======================================================

this is form tag but let see in deep that is 

action =""

we know what is action attribute in form tag where we will write the page which we want to display

but here we wrote like 

action="{% url 'contacts-new' %}"

so ,,,,,, let us think some think else..... ie.,   

{%%},,,,, ok what is this ?????? any idea

the answer for this is django template tags

so first  we will see what is template tags.......

 so in django we will use variable,tags,filters and decorators....

Django default built in:

{} is variables

{variable | variable condition} is filters

{%%} is tags

let see with filter and tags in next post......
