I've created a form that allows a user to edit a datum in a model.
However, when a user performs an edit, django adds that value as a new
datum rather than editing the existing datum in the database. Any idea
what's wrong?
#Model
#################################################################
class Recipe(models.Model):
recipe_name = models.CharField(max_length=100,
verbose_name='Recipe Name')
ingrediants = models.TextField(blank=True,
verbose_name='Ingrediants')
instructions = models.TextField(blank=True,
verbose_name='Instructions')
external_url = models.URLField(blank=True, verbose_name='External
URL')
cuisine = models.ForeignKey(Cuisine)
course = models.ForeignKey(Course)
image = models.ImageField(blank=True, upload_to='img2/')
thumbnail = models.ImageField(blank=True, upload_to='img/thumbs/')
one_liner = models.CharField(max_length=100, blank=True,
verbose_name='Comments')
tag_list = models.ManyToManyField(Tag, blank=True,
verbose_name='Tags')
user = models.ForeignKey(User)
def __unicode__(self):
return self.recipe_name
class Admin:
pass
#ModelForm ####################################################
class RecipeForm(ModelForm):
class Meta:
model = Recipe
exclude = ('user','thumbnail','tag_list')
# View that creates form
####################################################
def testForm(request, recipe_id):
r = Recipe.objects.get(pk=recipe_id)
f = RecipeForm(instance=r)
return render_to_response('chef/test-form.html', {'form':f})
# View that processes form
##################################################
def editConfirm(request):
f = RecipeForm(request.POST, request.FILES)
if not f.errors:
modified_recipe = f.save(commit=False)
modified_recipe.user = User.objects.get(id=1) #placeholder
until I add users; necessary for FK relation
modified_recipe.save()
return render_to_response('chef/edit-confirm.html', {'recipe':
modified_recipe})
else:
msg = 'Form not valid'
return render_to_response('chef/error.html', {'msg':msg})
# Template w/Form ######
<html><head>
<title>Add New Recipe</title>
<link rel="stylesheet" type="text/css" href="/media/style/style.css" /
>
</head><body>
<table> <form enctype="multipart/form-data" method="post" action="/
chef/edit-confirm/" method="post">
{{ form.as_table }}
<tr>
<td><input type="submit" value="Save Changes"></td>
<td><input type="submit" value="Cancel"></td>
</tr>
</form></table>
</body>
</html>
Thanks all!
