I'm using the standard pattern for handling a POST request form
submission, even though the form is submitted by JavaScript as an
XMLHttpRequest, and the date validation is not working. I added some
logging statements to find the problem and I get the error message
"MyModelForm' object has no attribute 'date' " even though it
definitely has that attribute, as shown in the logs below. Django is
generating the error message for that field in form.errors, but it
never gets put into the field-specific errors such as
form.date.errors. Does anyone know why?
Here's the model and form definition in models.py:
class MyModel(models.Model):
....
date = models.DateField(help_text="Please use the following format:
<em>YYYY-MM-DD</em>.")
....
class MyModelForm(ModelForm):
class Meta:
model = MyModel
exclude = ('user', 'date_added', 'active')
And here's the view:
def addtest(request, region):
if request.method == 'POST': # form submitted or ajax data initial
load..
form = MyModelForm(request.POST) # A form bound to the POST
data
if form.is_valid(): # All validation rules pass
# add entry to database here
else: # initial ajax load or error
if 'loadAll' in request.POST: #ajax load
logging.debug( "initial ajax load")
else:
logging.debug( "form errors found, form is: %s" %
form)
logging.debug( "form errors found: form.errors%s" %
form.errors)
logging.debug( "form.date.errors: %s" %
form.date.errors)
Here is the log output (irrelevant stuff omitted):
form errors found, form is:....
<tr><th><label for="id_date">Date:</label></th><td><ul
class="errorlist"><li>Enter a valid date.</li></ul><input type="text"
name="date" value="02//2009" id="id_date" /><br />Please use the
following format: <em>YYYY-MM-DD</em>.</td></tr>
....
form errors found: form.errors<ul class="errorlist"><li>date<ul
class="errorlist"><li>Enter a valid date.</li></ul></li></ul>
