Django ImportError: No module named admin
As a result of attempting to update admin.py of one of my Django apps, I
now get a Server Error (500) that has brought my site down. When I import
admin from django.contrib, I get the following traceback:

Django Forms vs Angularjs
I am a new comer to Django. Last four weeks I have been working on web application purely created with Django framework. I realized that Django forms are very cumbersome to use. I'd rather have DRF (rest framework) and just angularjs form. I am sure alot users will bombard me tons of oppositions. I'd like to hear the oppositions and critics maybe I am missing some points and knowledge. Thanks, -- You received this message because you are subscribed to the Google Groups "Django users" group.

You won't be modifying the model. Just the form.
You need to tell Django to render the form using the css clases you want.
There are a few ways of doing that. One is Fred's way:
phone = forms.CharField(
required = True,
max_length = 50,
label = u'',
widget = forms.TextInput(
attrs={
'class' : 'form-control',
}
)
You can also do a custom template. So instead of letting Django render the
form, you code the html yourself.
This is, instead of:
{{ form.as_p }}
do something like:
{% csrf_token %}
...
My favorite is to install django-crispy-forms, but may be overkill at the
moment since you are just learning Django. If you are comfortable using
modules/third-party apps, your template will be:
{% load crispy_forms_tags %}
{% crispy form %}

Norberto

Re: Forms in Django
Stanislav (aka Stanley?),
As my company motto says: "Glad to be of service!".
I'm very impressed with Django. It's a mature product that does
a good job of:
"Making simple things easy, and complex things possible"
It has good simple default behaviors, but also hooks that you
can use to drill down to more detail when necessary.
For example, in my Django templates, I sometimes use:
{{form}}
but sometimes have to resort to:
{{ form.first_name }}
{{ form.last_name }}
{{ form.phone }}
and occasionally even:
{{ form.first_name.value }}
{{ form.first_name.label }}
{{ form.first_name.errors }}
{{ form.last_name.value }}
{{ form.last_name.label }}
{{ form.last_name.errors }}
{{ form.phone.value }}
{{ form.phone.label }}
{{ form.phone.errors }}
Similarly, in my Django ModelForms, I sometimes use:
class PersonModelForm(forms.ModelForm):
class Meta:
model=Person
but sometimes have to resort to:
class PersonModelForm(forms.ModelForm):
class Meta:
model=Person
fields = ['first_name', 'last_name', 'phone',]
and occasionally even:
class PersonModelForm(forms.ModelForm):
class Meta:
model=Person
exclude = ['middle_name',]
or take over a field explicitly as:
phone = forms.CharField(
required = True,
max_length = 50,
label = u'',
widget = forms.TextInput(
attrs={
'class' : 'form-control',
'id' : 'my_custom_HTML_id',
'placeholder' : 'Phone',
}
),
)
or even give up on doing it all declaratively and do something
more dynamic in the __init__() of the Form, as:
def set_placeholders_from_labels(form):
for field in form.fields.itervalues():
field.widget.attrs['placeholder'] = field.label
class PersonForm(forms.Form):
def __init__(self, *args, **kwargs):
super(Donate2Form, self).__init__(*args, **kwargs)
set_placeholders_from_labels(self)
self.fields['amount'].widget.attrs['placeholder'] = ""
if some_special_reason():
self.fields['amount'].initial = "100"
keep_enabled = ['first_name','last_name']
if some_mode_where_we_need_some_fields_disabled():
for field in self.fields:
if field not in keep_enabled:
self.fields[field].widget.attrs['disabled'] = True
And with validation of user-entered data, I can declare many
validation rules on the declarations of the fields, and can do
validation programmatically in the clean_field_name() methods
and the overall clean() method. Or can even use the clean()
method of the Model instead of the clean() method of the form.
The ORM has similar hooks. I can use it simply, to get() and
save() models from and to the DB. Or can do fancier queries.
Or can drop down into raw SQL if necessary.
And I can use middleware to inject all sorts of useful functionality
into the HTTP request/response cycle, to change or add to the
default behavior, add caching of DB data, Django templates,
and fully assembled Django pages, etc.
And I can hook into Django "signals" for more sophisticated
needs.
Very powerful!
And I've found the community to be extraordinarily friendly and
helpful also.
Enjoy!
