hi..need help..

Here are the model :


class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    slug = models.SlugField(max_length=50, unique=True, help_text='Unique Value for Article page URL, created from title.')
    is_publish = models.BooleanField(default=False)
    categories = models.ManyToManyField(Category)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
   
    class Meta:
            db_table = 'post'
            ordering = ['-created_at']
            verbose_name_plural = 'Posts'
           
    def __unicode__(self):
        return self.title
   
    @models.permalink
    def get_absolute_url(self):
        return ('article_post', ())


here are my view :

def myadmin_change_post(request, template_name='blog/admin/change_post.html'):
    try:
        id= request.GET.get('id','4')
    except ValueError:
        id=1
    #post = get_object_or_404(Post,pk=id)
    post = Post.objects.get(pk=id)
    form = AdminPostForm(initial=post)
    return render_to_response(template_name,locals(),context_instance = RequestContext(request) )

here are the template :
{% extends "myadmin/index.html" %}

{%block content %}
<br /><br />
<table class="formtable">
<form action="" method="post">
{% csrf_token %}
    <tbody>
    {% for field in form.visible_fields %}
            {% if forloop.first %}
                {% for hidden in form.hidden_fields %}
                {{ hidden }}
                {% endfor %}
            {% endif %}
            <tr class="{% cycle 'altRow' 'evenRow' %}">
                <td>{{ field.label_tag }}</td>
                <td>{{ field }}
                    {{ field.errors }}
                </td>
            </tr>
    {% endfor %}
    </tbody>
</table><input type="hidden" name="next"  value="{{ reuest.path }}">
<input type="submit" value="Submit" />
</form>
</table>

{% endblock %}

The problem is, when in the view, the form is unbound the page display .
when i bound the form like this :

form = AdminPostForm(initial=post)  => generate error in template
but when    
form = AdminPostForm() => No error but the field all empty

What i intend to do is, edit the data in the form, which like change form/edit form.
any clue for this error..
the error are :

This line: 
    form = AdminPostForm(initial=post)

should be
    form = AdminPostForm(instance=post)

Hi Daniel,

i change it to instance, but still got other errors :


def myadmin_change_post(request, template_name='blog/admin/change_post.html'):
    try:
        id= request.GET.get('id','4')
    except ValueError:
        id=1
    #post = get_object_or_404(Post,pk=id)
    post = Post.objects.get(pk=id)
    form = AdminPostForm(instance=post)

    return render_to_response(template_name,locals(),context_instance = RequestContext(request) )

the form :

class AdminPostForm(forms.Form):
   
   
    cat_choices = [('private','private')]

    title = forms.CharField(widget=forms.TextInput(attrs={'size':'20','value':'','class':''}),label='Title')
    content= forms.CharField(widget=forms.Textarea(attrs={'cols':'40','rows':'5'}),label='Content')
    slug = forms.CharField(widget=forms.TextInput(attrs={'size':'20','class':''}),label='Slug')
    is_publish = forms.BooleanField(label='Publish')
    categories = forms.ChoiceField(choices=cat_choices)
    created_at = forms.DateTimeField(widget=forms.DateTimeInput(),label='Created at')
    modified_at = forms.DateTimeField(widget=forms.DateTimeInput(),label='Modified at')

any clue where the error migh be..

      Your form is not a model form, and so you cannot pass instance=post.
      Since it is just a regular form, you should pass a dictionary of
      values, with the keys of the dictionary being the names of the fields.

      If the form is representing a model, you should be using a model form.

      Cheers

      Oh i see..

      i read the manual, the django book, no such information about that..
      oh my..better update the manual there..

      thanks for your quick explanation then, i think not a good way to manualy assign a dictionarry to the form, not like in the documentation / book of django. now i get it.

      Thanks

      The Django Book is a useful general introduction; but now more than 2
      years old. In a framework like Django, which is under constant
      development, such old information gets out-of-date very fast. Tom
      correctly pointed you to the docs; and that is really the best place
      to work from now that you are doing specific development.
