running template system standalone on django 1.7.1 results in AppRegistryNotReady error

[Oliver Willekens]

I'm running into a problem when I'm trying to use Django's template system 
in a standalone application. Previously, in Django 1.4, I didn't have this 
problem.

As described at configuring the template system in standalone mode 
,
 
I first configure the settings of Django and then call one of the template 
loaders. However, I get an AppRegistryNotReady error:

In [1]: from django.conf import settings

In [2]: settings.configure(**{'TEMPLATE_DIRS': 
('/home/oliver/projects/autodelayv3/templates',), 'TEMPLATE_LOADERS': 
('django.template.loaders.filesystem.Loader',)})

In [3]: from django.template.loader import render_to_string

In [4]: render_to_string('webform.html', {'first_name': 'Oliver'})

Re: Django 1.7 problem

[Andreas Kuhne]

Ok,

What I did was modify how the dbgettext plugin loaded and changed the
registrations of the models.

You shouldn't have this problem without the plugin. Can you get the server
to run without apache? If you just use manage.py runserver?

Andréas

I have posted the entire issue in another post. After that I found your

I m beginner in Django. I have configured Django/Python/ Apache/Mod_wsgi on 
EC2 Amazon Windows instance. I see the similar error. I am not using any 
pluggins. The project is attempt to make Django work on Apache... and it 
not working.

 Indeed there is! See

 django.apps.AppConfig.ready

 Yes, admin.autodiscover now runs in the admin's AppConfig.ready() in
 Django 1.7, so that would have been a good place to start looking :-)

Hi Sarfaraz,

Are you also having problems with the dbgettext plugin? Or is it with
another plugin?

Re: django form field validation and error display

[James Schneider]

You should remove the inner else: clause and the redirect() line. If
is_valid() fails, the last return statement will be used, which will pass
along the bound form in signup_form that was snagged inside of your first
if statement. Mimic the behavior here:
https://docs.djangoproject.com/en/1.7/topics/forms/#the-view

BTW, django.shortcuts.redirect should handle the reverse() for you, so you
can take that out to make your code a bit cleaner. Also, not sure if this
is a copy/paste issue, but I think render() requires that request be sent
along as the first argument, although I don't use FBV's, so don't quote me
on that.

django form field validation and error display

[赵飞]

I want to make a signup page just like:


When user click signup, I want to check the if the two password are the 
same, when not, give a error message after "confirm password".  Here is my 
code:

*forms.py*

























*class SignupForm(forms.Form):username = forms.CahrField(
label=_("username"),max_length=30,)email = 
forms.EmailField(label=_('email'),)password_1 = forms.CharField(
label=_("password"),widget=forms.PasswordInput,)password_2 
= forms.CharField(label=_("password_confirmed"),
widget=forms.PasswordInput,)def clean_password_2(self):
password_1 = self.cleaned_data.get("password_1")password_2 = 
self.cleaned_data.get("password_2")if password_1 and password_2 and 
password_1 != password_2:raise 
forms.ValidationError(_('password confirm failed'))return 
password_2 signup.html*


{% csrf_token %}

{% for field in form %}

{{ field.label_tag }}
{{ field }}
{{ field.errors }}

{% endfor %}



{% trans "Already have accounts?" 
%}
 



*views.py*

def signup_post(request):
if request.method == 'POST':
signup_form = forms.SignupForm(request.POST)

if signup_form.is_valid():
signup_info = signup_form.cleaned_data
username = signup_info['username']
email = signup_info['email']
password = signup_info['password_1']
user = User.objects.create_user(
username=username,
email=email,
password=password)
user.save()
# redirect to main page(not written so far)
else:
# I guess something wrong here, but no idea how to fix it.
return redirect(reverse("accounts:signup"))

else:
signup_form = forms.SignupForm()

return render(reverse("accounts:signup"), {'form': signup_form}) 

Can anyone help me out? 
*Thanks!*

 Hi,

 I have the following pseudo model that I will use as the basis of a 
 modelformset:

 class Entry:
 athlete = ForeignKey(athlete)
 category = ForeignKey(category)
 race_number = IntegerField

 I have a page that displays each athlete's details so the choice of 
 athlete has already been made. I want to add a formset that allows a user 
 to specify a race_number for each of the possible categories available.

 An obvious way would be for there to be one Entry for each 
 athlete/category, but in practise this will result in a large entry table 
 that is only ~10% actual data, with the rest being superfluous rows. I'd 
 prefer to avoid this.

 Let's assume that an athlete is already entered in 2 categories out of 
 a possible 10. The queryset will return the 2 existing entries, and I can 
 use extra=8 to add in the other possibilities. However, I am not yet done. 
 I want to do the following and would like advice on how to accomplish this:

1. The category for each the 8 possible new entries needs to be 
assigned before displaying the form - I already know what they are and 
 want 
to display these categories to the user, leaving the race_number as the 
only input field.
2. The categories have a particular (chronological) order that I 
want respected in displaying the forms to the user, so the 2 existing 
 and 8 
possible new categories need to be interspersed to follow the correct 
 order.
3. When it comes time to save the formset, I want only those 
categories that have been changed by having a race_number assigned or 
removed to be saved. I want the entries where the race_number has been 
removed to remain in the entry table. I think I need a way to detect 
 and 
remove the forms that have not been changed by the user before saving 
 the 
formset.

 Any pointers as to how to do this?

 Thanks!
 R.

porting to 1.7

I have hit a snag and reading the relevant ticket has left me none the 
wiser

RuntimeError: Conflicting 'category' models in application 'smartpages': 
 and .

this is the structure

jade - directories( apache2, bin, jadeempire, lib
jadeempire - directories(jadeempire) files(manage.py)
jadeempire - directories(various apps) files(__init__.py, cp.py, 
settings.py, urls.py, wsgi.py)

>>> import sys
>>> print(sys.path)
['/home/jones124/webapps/jade/jadeempire', 
'/home/jones124/webapps/jade/lib/python2.7/Django-1.7.1-py2.7.egg', 
'/home/jones124/webapps/jade/lib/python2.7', 
'/home/jones124/lib/python2.7', '/usr/local/lib/python27.zip', 
'/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', 
'/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', 
'/usr/local/lib/python2.7/lib-dynload', 
'/usr/local/lib/python2.7/site-packages', 
'/usr/local/lib/python2.7/site-packages/PIL']

I kind of understand that that the model is being addressed twice and under 
1.7 that is now forbidden but where and how I do not know, any help much 
appreciated

Re: how can I choose option price from checkbox option and calculate the sum.

[rdyact]

I tried to like this but still got problem. I think Only thing to do more 
is "How can I link the price value to check option's value?"
What is wrong?  (It's still tough to the newbie.)

 javascript* I put on html file.


$(document).ready(function() {
$("input").click(function(event) {
var total = 0;
$("input:checked").each(function() {
total += parseInt($(this).val());
});
if (total == 0) {
$('#TotalCost').val('');
}
else {
$('#TotalCost').val('$' + total);
}
});
});
   


***  I changed the code in *single.html *as below



{% if product.choice_set.all %}
 {% for item in product.*choice*_set.all %}
   {{ item.name }}{{ 
item.price|capfirst }}Add price 
 {% endfor %}

*Total Choice's Amount* :  
{% endif %}
