I was looking into the generic views that existed and I hoping that this view would work for me. I expect that the view will display current model as an editable form. But I am having issues, I get some odd exception. Can someone that has experience please help me?
-- UpdateView
- class django.views.generic.edit.UpdateView
A view that displays a form for editing an existing object, redisplaying the form with validation errors (if there are any) and saving changes to the object. This uses a form automatically generated from the object's model class (unless a form class is manually specified).
Ancestors (MRO)
This view inherits methods and attributes from the following views:
- django.views.generic.detail.SingleObjectTemplateResponseMixin
- django.views.generic.base.TemplateResponseMixin
- django.views.generic.edit.BaseUpdateView
- django.views.generic.edit.ModelFormMixin
- django.views.generic.edit.FormMixin
- django.views.generic.detail.SingleObjectMixin
- django.views.generic.edit.ProcessFormView
- django.views.generic.base.View
Attributes
- template_name_suffix
The UpdateView page displayed to a GET request uses a template_name_suffix of '_form'. For example, changing this attribute to '_update_form' for a view updating objects for the example Author model would cause the default template_name to be 'myapp/author_update_form.html'.
- object
When using UpdateView you have access to self.object, which is the object being updated.
Example myapp/views.py:
from django.views.generic.edit import UpdateView from myapp.models import Author class AuthorUpdate(UpdateView): model = Author fields = ['name'] template_name_suffix = '_update_form'
Example myapp/author_update_form.html:
<form action="" method="post">{% csrf_token %} {{ form.as_p }} <input type="submit" value="Update" /> </form>
