Re: Form errors in ListFormsetView created by adding methods to a ListView.

[VISHESH MANGLA]

 Sorry , I should have posted the template
well, the error is,  hmm, 
suppose you are at  page 1  , now you clicked next and you got to page 2 
and the `post` method is hit. It will get page number as 2. But for  
formset , the initial data will have to be compared with  page "1" s data 
not "2". In the current scenario ,the initial_data  was the page2's but the 
data that was posted was for page 1. So you see the problem? It took me 
quite long to understand this.

  
 


{% extends 'adminuser/portal.html' %} 
{% block main-content %}
{% load my_extra_filters %}
 {% if messages %}
{% for message in messages %}

<div class="alert alert-success" role="alert">{{ message }}</div>
{% endfor %}
 {% endif %}

<form method="post" >

  {% csrf_token %}
  {{ formset.management_form }}

  <table class="table">
    <thead>
      <tr>
        <th scope="col">Name</th>
        <th scope="col">Pan ID</th>
        <th scope="col">Print Report?</th>
      </tr>
    </thead>

    <tbody>
      {% for user_form in formset %}
        {% for user_data in object_list %}
          {% if forloop.counter0 == forloop.parentloop.counter0 %}
              <tr>
                <td>{{user_data.get_full_name.}}</td>
                <td>{{user_data.PAN_ID}}</td>
                {{user_form.PAN_ID}}
                
                <td>{{user_form.print_report_check}}</td>
              </tr>
      
          {% endif %}
        {% endfor %}
    
      {% endfor %}


    </tbody> 
  </table>
