How to autofill a form template with values stored in database in Django?

Akhil Nadh PC

I would like to fill my edit_post.html with the values already stored in the database . My edit url is http://hostname/edit_Post/960 . "960" corresponds to the item id in my database . I request with that ID to update its contents.

I wann the contents to appear here :-

edit_Post.html

<form id="category_form" method="post" action="/edit_Post/">

    {% csrf_token %}

    {% for field in form.visible_fields %}            
        {{ field.errors }}
        <input type="text" placeholder='{{ field.help_text }}'>
    {% endfor %}

    <input type="submit" name="submit" value="Create Post" />
</form>

urls.py

url(r'^edit_Post/(?P<id>\d+)', 'blog.views.edit_Post'),

forms.py

class addPostForm(forms.ModelForm):
    title = forms.CharField(max_length=128, help_text="Please enter the title ")
    author = forms.CharField(max_length=128, help_text="Please enter the Author ")
    bodytext = forms.CharField(max_length=128,
                               help_text="Please enter the Body",
                               required=False)

    # An inline class to provide additional information on the form.
    class Meta:
        # Provide an association between the ModelForm and a model
        model=posts
        fields = ('title', 'author','bodytext')

finally views.py

def edit_Post(request, id):
    context = RequestContext(request)
    instance=posts.objects.get(id=id)
    form = addPostForm(instance=instance)
    if request.method == "POST":
        form = addPostForm(request.POST,instance=instance)
        if form.is_valid():
            form.save(commit=True)
            confirmation_message = "Post information updated successfully!"
            return HttpResponseRedirect('/home')
        else:
            print form.errors
    else:
        form=addPostForm(instance=instance)
    return render_to_response('edit_Post.html', {'form': form}, context)

my model.py

class posts(models.Model):
    author = models.CharField(max_length = 30)
    title = models.CharField(max_length = 100)
    bodytext = models.TextField()
    timestamp = models.DateTimeField(default=datetime.now, blank=True)

Django would already do this, if you hadn't bypassed its mechanism of outputting fields. In your template you should do this:

{% for field in form.visible_fields %}
    {{ field.errors }}
    {{ field }}
{% endfor %}

If you want to keep the placeholder functionality, add that in the form class itself:

class addPostForm(forms.ModelForm):
    title = forms.CharField(max_length=128, widget=forms.TextInput(attrs={'placeholder': 'Please enter the title'}))
