from django.db import models django.contrib.auth.models import user class userprofile(models.model): #esta linea es requerira. linkea userprofile united nations user model user = models.onetoonefield(user) #atributos adicionales about_me = models.textfield(max_length=100,default='',blank=true) experience = models.textfield(max_length=250,default='',blank=true) offers = models.textfield(max_length=110,default='',blank=true)

this template:

{%extends 'base.html'%} {%block content%} {% if user.is_authenticated %} <h1>edita tu perfil</h1> <form id='profile' method='post' action='/edit_profile/'> {% csrf_token %} {{profile.as_p}} <button type='submit'>editar</button> </form> {%endif%} {%endblock%}

thanks before hand

edit:

the error in views.py needed add together instance form, this:

form = userprofileform(data=request.post, instance=profile)

this finish views.py:

def edit_profile(request): try: profile = request.user.userprofile except userprofile.doesnotexist: profile = userprofile(user=request.user) if request.method == 'post': form = userprofileform(data=request.post, instance=profile) if form.is_valid(): form.save() homecoming httpresponse("exito!") else: form = userprofileform(instance=profile) else: form = userprofileform() homecoming render(request, 'editprof.html', { 'form': form})

problem user in userprofile required, not setting user field in userprofileform. database didn't user_id, tried set null on field, field have not not null constraint. can set null=true on field definition in userprofile model, or overwrite save (or is_valid) form method set user automatically, or add together user field userprofileform, or whatever want.
