    <p>I'm trying to create a page of my <code>Django 1.5</code> project where users can change their presonal informations. I wrote a form:</p> <pre><code>class UserModify(forms.Form): middleschool = 'MS' highschool = 'HS' university = 'U' blank = '' male = 'M' female = 'F' mastercard = 'MC' maestro = 'M' visa = 'V' americanexpress = 'A' school_choices = ((middleschool, 'Middle School'), (highschool, 'High school'), (university, 'University'), (blank, 'Not Defined'),) sex = ((male, 'Male'), (female, 'Female'), (blank, 'Not defined'),) card_choices = ((mastercard, 'MasterCard'), (maestro, 'Mestro'), (visa, 'Visa/Visa Electron'), (americanexpress, 'American Express'),(blank, 'Not Defined')) password = forms.CharField(label = 'Password', widget=forms.PasswordInput) repassword = forms.CharField(label = ' Reinstert password', widget=forms.PasswordInput) name = forms.CharField(label = 'Name', required=False) surname = forms.CharField(label = 'Surname', required=False) school = forms.ChoiceField(choices = school_choices, required=False, label='What school are you enrolled?', initial = blank) birthdate = forms.DateField(label = 'Birth date', required=False, widget=forms.extras.SelectDateWidget(years=range(1950, 2015))) sex = forms.ChoiceField(choices = sex, required=False, label='Sex', initial = blank) city = forms.CharField(label = 'City', required=False) paypal_info = forms.EmailField(required=False,) card_type = forms.ChoiceField(choices = card_choices, label='Card type', required=False) card_info = forms.CharField(min_length = 16, max_length = 16, label = 'Your card number', required=False,) def clean_repassword(self): repassword = self.cleaned_data['repassword'] password = self.cleaned_data['password'] if repassword != password: raise forms.ValidationError("Verification password different from original password!") widgets = { 'password': forms.PasswordInput(), 'birthdate': forms.extras.SelectDateWidget(years=range(1950, 2014)) } </code></pre> <p>and this is the relative view:</p> <pre><code>def usermodify(request, user): mod_user = User.objects.get(username = user) if request.method == 'POST': form = UserModify(request.POST) if form.is_valid(): cd = form.cleaned_data mod_user.password = cd['password'] mod_user.first_name = cd['name'] mod_user.last_name = cd['surname'] mod_user.save() profile = mod_user.get_profile() profile.school = cd['school'] profile.birthdate = cd['birthdate'] profile.sex = cd['sex'] profile.city = cd['city'] profile.save() return render(request, 'user.html', {'request':request, 'view_user': mod_user, 'view_user_profile': profile}) else: form = UserModify() return render(request, 'user_modify.html', {'form': form, 'request': request, 'modify_user': mod_user}) </code></pre> <p>The form's rendering is as simple as it can get for now:</p> <pre><code>&lt;form action="" method="post"&gt; {% csrf_token %} {{ form.as_p }} &lt;input type="submit" value="Modify"&gt; &lt;input type="reset" value="Reset"&gt; &lt;/form&gt; </code></pre> <p>What I wantetd to do is populate the form by default with the current values in the object so that the User have to change only the one in which is interested and keep the others.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
