I was trying out forms and created a class and its form
class MyCategory(models.Model):
name=models.CharField(max_length=10)
description=models.TextField(help_text='a description about the
category')
slug=models.SlugField(unique=True,help_text='will be auto generated
from name')
class Meta:
verbose_name_plural="MyCategories"
def __unicode__(self):
return self.name
def get_absolute_url(self):
return ('myapp_category_detail',(),{'slug':self.slug})
get_absolute_url=models.permalink(get_absolute_url)
classMyCategoryForm(ModelForm):
class Meta:
model=MyCategory
I set the slug to be auto generated in admin.py
class MyCategoryAdmin(admin.ModelAdmin):
prepopulated_fields= {'slug':['name']}
ordering=['name']
After that I created an edit view for the class
def edit_category(request,slug):
cat=get_object_or_404(MyCategory,slug=slug)
if request.method=='POST':
form=MyCategoryForm(request.POST,instance=cat)
if form.is_valid():
form.save()
redirect('myapp_category_list')
else:
print 'edit_category::invalid form'
form=MyCategoryForm(instance=cat)
else:
form=MyCategoryForm(instance=cat)
return render_to_response('myapp/edit_category.html',
{'categoryform':form})
In the edit_category.html I displayed the form as
<form method='post' action='{% url edit_category
categoryform.instance.slug %}' >
<table>
{{ categoryform.as_table }}
</table>
<input type='submit' name='Save' />
</form>
When the template is rendered it shows the helptext which I provided
in the model's slugfield.But unlike in the django admin 's edit
page ,the slug is not auto generated when I type in a new name for the
category.
Similarly I tried an add category page.Here also the slug is not auto
generated,even though the helptext says that it will be.I have enabled
javascript for my browser.Do I have to write a javascript for each of
these pages or can I use some script the admin uses?
I am only getting familiar with the basics..so please bear with the
newbish doubts
thanks
harry
