I've finally figured it out after weeks of troubleshooting and here's how I
do it.
In the original post, my views takes in the request from form1 and renders
it to form2. I would get the dreadful "Management Form Data is Missing"
error no matter what I did and it led to asking a bunch of questions on
here. I decided to isolate the 2 forms to see if that rendered. It took a
few tries before getting both forms and templates to work separately. What
I noticed was form1.html's action was equal to "none" which was what I
wanted. It would render and posted the form with the errors to itself
without redirecting to another page. I then discovered that the address
was still hooked to form1 instead of form2 after it had rendered. In
another word when form1 rendered the data to form2, the address was still
on userinfo/form1.html when it should have been userinfo/form2.html in
order for action to call the correct form in views. The magic that I used
to fix the issue was *HttpResponseRedirect*. I saved the data retrieved
from form 1 in a session and recovered it from beginning of form 2. I used
session to render data from form 2 instead of rendering directly from form
1.
*Changes to form1 in views.py*
- Save the data in a session for access in different part of views
- Re-direct to form2 instead of render data from form1
def form1 (request):
...
if formset.is_valid ():
location = request.POST ['site']
data = formset.cleaned_data
request.session ['names'] = data
return HttpResponseRedirect ('form2')
...
*Changes to form2 in views.py*
- Retrieve data from session
- Do something with data from form2. For my case, I merged both
dictionary into one.
def form2 (request):
data = request.session ['names']
...
if checkbox_formset.is_valid ():
for i, form in enumerate (checkbox_formset.cleaned_data):
data [i].update (form) # This will give me a list of name
dictionary with the checkbox appended
context = {'data': data}
return render (request, 'userinfo/success.html', context)
else:
checkbox_formset = CheckBoxFormSet (prefix = 'checkbox')
context = {'checkbox_formset': checkbox_formset, 'data': data,
'location': location}
return render (request, 'userinfo/form2.html', context)
*form2.html*
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
{% load staticfiles %}
<link rel="stylesheet" type="text/css" href="{% static
'userinfo/style.css' %}" >
<title>Confirmation</title>
</head>
<body>
<h2>Submitted Entries:</h2>
<form action="form2" method="POST">{% csrf_token %}
<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th class="center">Location</th>
<th class="center">Overwrite</th>
<th class="center">Index</th>
</tr>
{% for info in data %}
<tr>
<td>{{ info.first_name }}</td>
<td>{{ info.last_name }}</td>
<td class="center">{{ location }}</td>
{{ checkbox_formset.management_form }}
<td class="center"><label for="id_checkbox-{{ forloop.counter0
}}-overwrite"></label>
<input id="id_checkbox-{{ forloop.counter0 }}-overwrite"
name="checkbox-{{ forloop.counter0 }}-overwrite" type="checkbox"/></td>
<td class="center">{{ forloop.counter0 }}</td>
</tr>
{% endfor %}
</table>
<p><input type="submit" value="Confirm">
<a href="{% url "addname" %}">
<button type="button">Cancel</button>
</a></p>
</form>
</body>
</html>
All there's left to do is create a template for success.html
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>Success</title>
</head>
<body>
<h2>Submitted Entries:</h2>
<ul>
{% for info in data %}
<li>{{ info.first_name }} {{ info.last_name }} {{
info.overwrite }}</li>
{% endfor %}
</ul>
<p><a href="{% url "addname" %}">Add more names</a></p>
</body>
</html>
Hope this will help some stragglers. Nevertheless, thanks to Bernardo for
helping me all along.
