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 :
