Example: I have 2 on a html page, which is a form (assume it is

The behavior of is_valid I see is:
When submit, the returned errors for the form are:

This field is

You get your boolean if you ``call`` the "is_valid" method.

The webpage shows the form populated with the data, BUT, is_valid() always

This is behavior seems a little strange but other way (errors being

Hi,
At the instant I initialize my form, the errors dict is filled,
although the documentation says, the validation happens after form
instance's is_valid() method is called.
Here is the demonstration:

>>> from blog.models import I

My issue has been solved. I used Dojo widgets in my template instead of
Django widgets. Then those reprinted data were not displayed. But when I
removed Dojo widgets, it is working properly.
Can you suggest an efficient way to integrate Django and Dojo, any links or

Well, if f.bound is True and f.is_valid() is false, f.errors will

However, is_valid is not telling me that the form is correct.

I am confused about the following:
If I get a previous saved record, transform it into a form instance
and then create a form out of it, the data is not valid nor bound (see
below). However, if I print out the form, all fields are populated
correctly.
Am I missing a step?
