That makes sense. Thank you. --M On Sunday, January 3, 2016 at 8:05:21 AM UTC-6, knbk wrote: > > >>> uf = UsersForm(u) > > Here you are passing the user instance as if it were the POST data. The > form expects a dictionary or None as the first argument. `form.is_bound` > simply checks `data is

Re: ModelForm.is_valid() doesn't work the first time but does the second

>>> uf = UsersForm(u) Here you are passing the user instance as if it were the POST data. The form expects a dictionary or None as the first argument. `form.is_bound` simply checks `data is not None`, which is True in this case. If you want a bound form, you should pass a dictionary with the

Well, it's not supposed to be bound if you don't pass any data to it the "instance" in the ModelForm (if i remember correctly) just sets the initial values for the fields when you render the form in HTML and modifies that instance when you call "save" on the ModelForm. On Sun, Jan 3, 2016 at 1:29

Not studying; I’m working on a website that will be used to register people for an event, but it is my first Django site. I’m aware that I can add to the existing user model, and I may. However, this is just my first attempt to create a model and form and save data to the database. I don’t thi

Re: ModelForm.is_valid() doesn't work the first time but does the second

"First, why does uf.is_valid() return" because you called "uf.is_valid" (note the lack of parenthesis), that's just a reference to the method and does not call it. "Second, why does uf.save() return that stacktrace the first time I call it, but the second time I call it, the object saves? " As f

Re: ModelForm.is_valid() doesn't work the first time but does the second

I'm not sure what could be wrong with the database settings. If I just create an instance of the model and save it, it saves to the database: >>> u.email

Re: ModelForm.is_valid() doesn't work the first time but does the second

Is_valid is working. You have problem with save. Check database setting. 3 січ. 2016 04:18 "Michael Molloy" пише: >ve > This is running in Openshift with Python 3.3 and Django 1.8.4 > > Here's my model: > > class Users(models.Model): > first_nm = models.CharField('First Name', max_length=100)

ModelForm.is_valid() doesn't work the first time but does the second

This is running in Openshift with Python 3.3 and Django 1.8.4 Here's my model: class Users(models.Model): first_nm = models.CharField('First Name', max_length=100) last_nm = models.CharField('Last Name', max_length=100) email = models.CharField('Email Address', max_length=200, unique=
