Hello,
I'm using Django ModelForm on add/edit URLs which are both sharing a single
template file. The
code I'm working with is like this:
class WebappAuthorize(models.Model):
institution_name = models.CharField(max_length=32, help_text="Enter your
institution name")
email = models.CharField(max_length=20, help_text="Example,
t...@example.com", default=get_current_user(object(), 'email'))
institution_logo = models.FileField(upload_to=api.file_upload('files',
'logo'),
blank=True, help_text="Upload your institution logo")
institution_url = models.CharField(max_length=50, blank=True,
help_text="Example, http://example.com";)
phone = models.IntegerField(null=True, blank=True, help_text="Enter a
phone number")
class Meta:
db_table = u'authorize'
forms.py
------------
class AuthorizeForm(forms.ModelForm):
class Meta:
model = WebappAuthorize
views.py
------------
def get_current_user(request, **kwargs):
if kwargs['email']:
# select email from User where
request_email = User.objects.filter(email=request.user)
email = request_email.values('email')
edict = email[0]
return edict.get('email')
def authorize(request):
request_user = User.objects.filter(username=request.user)
username = request_user.values('username')
udict = username[0]
u = str(udict.get('username'))
context = {'page_title' : 'Authorize your institution'}
consumer_obj = WebappOauthConsumer.objects.filter(user=u) # get user_id
from user
print consumer_obj
c = consumer_obj.values('user_id')
for i in c:
if i.get('user_id') == u:
return redirect('update-authorize-institution', user=u,
action='update')
if request.method == 'POST':
authorize_form = AuthorizeForm(request.POST, request.FILES)
if authorize_form.is_valid():
print request.POST
ckey = consumer.generate(request.POST.get('institution_name',
''))
if ckey is not None:
oauthconsumer_model = WebappOauthConsumer()
oauthconsumer_model.user = User(u)
oauthconsumer_model.institution_name =
WebappAuthorize(request.POST.get(u'institution_name', ''))
oauthconsumer_model.consumer_key = ckey.get('consumer_key')
oauthconsumer_model.consumer_secret =
ckey.get('consumer_secret')
oauthconsumer_model.created = int(time.time())
oauthconsumer_model.changed = int(time.time())
oauthconsumer_model.save()
return redirect('update-authorize-institution', user=u,
action='update')
else:
print authorize_form.errors
else:
authorize_form = AuthorizeForm()
context['form'] = authorize_form
context['action'] = 'new'
context['consumer'] = consumer_obj.values().order_by('id')
for i in context['consumer']:
p = i
request.session['consumer'] = p
return render_to_response("webapp/authorize.html", context,
context_instance=RC(request))
And the edit view
------------------------
def edit_authorize(request, **kwargs):
context = {'page_title' : 'Update Authorize your institution'}
context['user'] = kwargs['user']
context['action'] = kwargs['action']
print request.session['consumer']
if request.method == 'POST':
authorize_form = AuthorizeForm(request.POST, request.FILES)
oauthconsumer_model.changed = date.today()
oauthconsumer_model.save()
else:
u = WebappOauthConsumer.objects.get(user=kwargs['user']) # Make sure
it returns a single user
authorize_form = AuthorizeForm(data=request.POST,
files=request.FILES, instance=u) # instance of WebAuthorize
context['form'] = authorize_form
return render_to_response("webapp/authorize.html", context,
context_instance=RC(request))
In each of these form fields, I want their values to be set on edit. A fix
I'm working with at the moment
is to store the values in session variables, then print it on the input
value property of each form field in
the template file.
{{ request.session.consumer.institution_name_id}}
<div class="group">
<label for="{{ form.institution_name.name }}"
class="label">{{ form.institution_name.label }}</label>
{% if action == 'update' %}
<input class="text_field" type="text"
disabled="disabled" name="{{ institution_name_id }}" value="{{
request.session.consumer.institution_name_id }}" />
{% else %}
<input class="text_field" type="text" name="{{
form.institution_name }}" value="{{
request.session.consumer.institution_name_id }}" />
{% endif %}
{{ form.institution_name.help_text }}
</div>
<div class="group">
<label for="{{ form.email.name }}" class="label">{{
form.email.label }}</label>
{{ form.email }}
{{ form.email.help_text }}
</div>
For example, on the email field, I want its value prepopulated on edit. I
tried using the default field option
on the model, but there's no easy way of getting logged in user outside
views.py. To provide a workaround,
I created a function in views.py which takes the request object as argument,
then I call the function in
models.py like so:
// in models.py
from webapp.views import get_current_user
email = models.CharField(max_length=20, help_text="Example, t...@example.com",
default=get_current_user(object(), 'email'))
But it seems impossible to import views.py into models.py. I'm getting:
ImportError: cannot import name get_current_user
Please, how can I get such functionality in my template file.
Thanks
