django adding quotes on subsequent submits - django

Question

Here's the goal: when the user submits the form, use one view to send the submitted data to the database, then redirect back to the form, but with the data pre-populated. This is mostly working, but something about my implementation is wrapping extra quotes around the string. For now, I'm just using a super-simple form, btw. I enter Billy, and the pre-pop is: "Billy", if I click submit again, it comes back as: "\"Billy\"", then "\"\\\"Billy\\\"\"", and so on (as far as I have tested, anyways.
relevant views are:
def editUsers(request):
if request.method == 'POST':
# create a form instance and populate it with data from the request:
form = usersForm(request.POST)
# check whether it's valid:
# process the data in form.cleaned_data as required
# redirect to a new URL:
name = json.dumps(form.data['user_name'])
request.session['editUserName'] = name
# call out to limboLogic.py to update values
test = name
return redirect('../users')
# if a GET (or any other method) we'll create a blank form
else:
return redirect('../users')
from .forms import *
def users(request):
form = None
if 'editUserName' not in request.session:
# create a blank form
form = usersForm()
else:
# form = equipmentForm(initial='jim') - used to make sure I was branching the if/else correctly
form = usersForm(initial={'user_name':request.session['editUserName']}, auto_id=False) #limboLogic.GetUserInfo(name))
return render(request, 'limboHtml/UserManagement.html', {'form': form})
form is simply:
class usersForm(forms.Form):
user_name = forms.CharField(label='New User\'s name', max_length=100)
and the template is:
{% extends "base.html" %}
{% block content %}
<div class="row">
<p>This is the user management page</p><br>
<form action="/edit/users.html" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="OK">
</form>
<br><p class="bold">This is below the form</p>
</div>
{% endblock %}
thoughts?

I can't quite say what the intracies are here, but the problem involves the fact that I was using a json class. I used this site as a guide and managed to fix the problem. note that the key aspect is inside the second if:
name = form.cleaned_data['user_name'] works fine,
name = json.dumps(form.data['user_name']) does not
the whole function as it now stands:
def editUsers(request):
if request.method == 'POST':
# create a form instance and populate it with data from the request:
form = usersForm(request.POST)
# check whether it's valid:
# process the data in form.cleaned_data as required
# redirect to a new URL:
if form.is_valid():
name = form.cleaned_data['user_name']
# name = json.dumps(form.data['user_name'])
request.session['editUserName'] = name
# call out to limboLogic.py to update values
test = name
return redirect('../users')
# if a GET (or any other method) we'll create a blank form
return redirect('../users')
