Hello,
I have a model Investor associated with a model User. Now I'm
implementing the registration form.
I want to store the name of the Investor in the Investor model and the
rest of information in the User model. So I have username, password,
name and email.
I have a registration form in order to input this information:
class RegisterForm(forms.Form):
username = forms.CharField(max_length=30)
password = forms.CharField(max_length=20, widget=forms.PasswordInput())
name = forms.CharField(max_length=50)
email = forms.EmailField(max_length=30)
Now I have a view to show this form, retrive the data, validate it and
store it in Investor and in User:
def register_user(request):
register_form = RegisterForm()
message = "User Registration"
if request.POST.get('submit') == 'Register':
postDict = request.POST.copy()
UserForm = forms.form_for_model(User)
user_form = UserForm(postDict)
if user_form.is_valid():
try:
user_form.save()
message = "User registered succesfully"
except:
message = "Database error"
invDict = {}
invDict['name'] = postDict.get('name', '')
invDict['userID'] = user_form.id
InvestorForm = forms.form_for_model(Investor)
iForm = InvestorForm(invDict)
if iForm.is_valid():
try:
i = iForm.save()
message = "User registered succesfully"
return
render_to_response('Authentication/login.html', {
'lForm': LoginForm(),
'message': message })
except:
message = 'Database Error'
user.delete()
else:
message = 'You entered invalid data in the form'
user.delete()
else:
message = "You entered invalid data in the form"
return render_to_response('Authentication/register.html',
{'uForm': register_form, 'message': message})
First of all, I want to say that I do not understand the relationship
between forms and models in Django. A form to ask and a model to
store? How to pass the form data to a model? Have I to pass it in
order to validate?
The problem with this code is that when I do not enter the name field
it says the form is invalid but the name field is optional. And the
second problem is that when I enter invalid data I don't see the
errors in each field.
This is the template used:
{% block title %}Registration form{% endblock %}
{% block content %}
<h3>{{ message }}</h3>
<form action="." method="post" >
<table>
<tr>
<td>Username:</td>
<td>{{ uForm.username }}</td>
<td>{{ uForm.username.errors }}</td>
</tr>
<tr>
<td>Password:</td>
<td>{{ uForm.password }}</td>
<td>{{ uForm.password.errors }}</td>
</tr>
<tr>
<td>Name:</td>
<td>{{ uForm.name }}</td>
<td>{{ uForm.name.errors }}</td>
</tr>
<tr>
<td>Email:</td>
<td>{{ uForm.email }}</td>
<td>{{ uForm.email.errors }}</td>
</tr>
</table>
<input type="submit" name="submit" value="Register" />
</form>
{% endblock %}
