do i always have to reload/return render a page to show the errors? if i press go back on browser, i see screens with the error message

2017-10-30 Thread fábio andrews rocha marques

Let's say i have a "register a new user" View and on this page, when the 
user forgets to inform a password or a username, i show a message to him on 
the same page saying "you forgot the password". The way i do this is by 
doing this(on my View.py in a function called cadastrarprofessor):

nomeusuario = request.POST['usuario'] #username
nomesenha = request.POST['senha'] #password
nomeemail = request.POST['email'] #email

if not nomeusuario:
return render(request,'cadastro.html',{'cadastrorealizadocomsucesso': 
False, 'error_message': "informe um usuário", 
'nomeemailcadastro':nomeemail, 'nomesenhacadastro':nomesenha})
elif not nomesenha:
return render(request,'cadastro.html',{'cadastrorealizadocomsucesso': 
False, 'error_message': "informe uma senha", 'nomeemailcadastro':nomeemail, 
'nomeusuariocadastro':nomeusuario})
elif not nomeemail:
return render(request,'cadastro.html',{'cadastrorealizadocomsucesso': 
False, 'error_message': "informe um email", 'nomesenhacadastro':nomesenha, 
'nomeusuariocadastro':nomeusuario})

And my template for this page(cadastro.html) is like this:

Cadastro

{% csrf_token %}
Usuário: 
{% if nomeusuariocadastro %}

{% else %}

{% endif %}


... (DO THE SAME TO SENHA/PASSWORD AND EMAIL)





{% csrf_token %}

{% if cadastrorealizadocomsucesso is True %}cadastro realizado com 
sucesso!{% endif %}
{% if error_message %}{{ error_message }}{% endif %}

So, every time the user forgets to mention a username or email or password 
in this screen, i use render to redirect the user to the same page but this 
time displaying a error_message. Let's say he did forget to fill the 
textfield with a username... he goes back to the same page and sees the 
error message. After that, let's say everything is right and he finally 
registers a new user, he sees "cadastro realizado com sucesso"(sucessfully 
registered new user) and stays on the same page. But when he goes back a 
page(pressing "back" on the browser), instead of going back to the page 
before the cadastro.html, he goes back to the same page cadastro.html but 
displaying the error message for the "you forgot to mention your username". 
I don't want him to go back to the same page with error message, i want to 
make him go back to my main menu. 
Is there a better approach to display error messages on the same page 
instead of using return render like this:
return render(request,'cadastro.html',{'cadastrorealizadocomsucesso': False,
 'error_message': "informe um usuário", 'nomeemailcadastro':nomeemail,
'nomesenhacadastro':nomesenha})
?

Re: QuerySet.extra and ticket #28756

2017-10-30 Thread Tim Graham

You aren't using Value correctly -- it's not for wrapping raw SQL. 
https://docs.djangoproject.com/en/dev/ref/models/expressions/#value-expressions

What I was trying to suggest is that you write your own expression class 
that generates the FIELD(...) SQL.

QuerySet.extra and ticket #28756

2017-10-30 Thread Brandon

In my original ticket (https://code.djangoproject.com/ticket/28756) I 
explained this:

I have reoccurring situation, when in a view.py function I need a queryset 
ordered by a set of identifiers. The order of those identifiers is 
dependent on factors outside of my control. Essentially in my view I am 
using modelformset_factory to generate a modelformset, then the usage of 
that modelformset instance requires queryset. It is that final queryset 
that must be ordered by the identifier whose order is externally determined.
So I use the .extra( ) function like below:

quali_results = ToxicologyCaseQualitativeResult.objects.filter(case_id=case.
id).select_related('test').order_by('test__name')

field_list = ["AMPHS","BARB","BNZ","BE","Ecstasy","METH","6AM","PCP","THC"] 
#Usually 
populated via retrieval of user settings.
if len(field_list) > 0:
field_list = field_list + [q.test.identifier for q in quali_results] 
fields = '"'+'","'.join(str(field) for field in field_list)+'"'
field_sql = "FIELD(`identifier`,"+fields+")"
quali_results = quali_results.extra(select={'field_sql' : field_sql}, 
order_by=['field_sql'])

quali_resultfs = QualitativeResultFormset(queryset=quali_results, prefix=
'quali_results')


This was closed by Tim Graham stating that I should be using "Query 
Expression ", 
which is fine. So the code became this:

from django.db.models import Value, CharField

quali_results = ToxicologyCaseQualitativeResult.objects.filter(case_id=case.
id).select_related('test')

field_list = ["AMPHS","BARB","BNZ","BE","Ecstasy","METH","6AM","PCP","THC"] 
#Usually 
populated via retrieval of user settings.
if len(field_list) > 0:
field_list = field_list + [q.test.identifier for q in quali_results] 
fields = '"'+'","'.join(str(field) for field in field_list)+'"'
field_sql = "FIELD(`identifier`,"+fields+")"
quali_results = quali_results.order_by(Value("FIELD(`identifier`,"+
fields+")",output_field=CharField()))

quali_resultfs = QualitativeResultFormset(queryset=quali_results, prefix=
'quali_results')

Which I agree is could be seen as better, and it doesn't use the 
Querset.extra( ) method. The only problem is that it doesn't work.

The first method generates this SQL:
SELECT (FIELD(`identifier`,"AMPHS","BARB","BNZ","BE","Ecstasy","METH","6AM",
"PCP","THC","AMPHS","BARB","BNZ","THC","BE","Ecstasy","METH","6AM","PCP")) 
AS `field_sql`, `toxicology_toxicologycasequalitativeresult`.`id`, 
`toxicology_toxicologycasequalitativeresult`.`case_id`, 
`toxicology_toxicologycasequalitativeresult`.`test_id`, 
`toxicology_toxicologycasequalitativeresult`.`detection`, 
`toxicology_toxicologycasequalitativeresult`.`result`, 
`toxicology_toxicologycasequalitativeresult`.`concentration`, 
`toxicology_toxicologycasequalitativeresult`.`outcome`, 
`toxicology_toxicologycasequalitativeresult`.`cutoff`, 
`toxicology_toxicologycasequalitativeresult`.`units`, 
`toxicology_toxicologycasequalitativeresult`.`comments`, 
`toxicology_toxicologyqualitativetestreference`.`id`, 
`toxicology_toxicologyqualitativetestreference`.`panel_id`, 
`toxicology_toxicologyqualitativetestreference`.`enabled`, 
`toxicology_toxicologyqualitativetestreference`.`name`, 
`toxicology_toxicologyqualitativetestreference`.`identifier`, 
`toxicology_toxicologyqualitativetestreference`.`analyte_id`, 
`toxicology_toxicologyqualitativetestreference`.`LOB`, 
`toxicology_toxicologyqualitativetestreference`.`LOD`, 
`toxicology_toxicologyqualitativetestreference`.`LOQ`, 
`toxicology_toxicologyqualitativetestreference`.`ULOL`, 
`toxicology_toxicologyqualitativetestreference`.`expression`, 
`toxicology_toxicologyqualitativetestreference`.`true_result`, 
`toxicology_toxicologyqualitativetestreference`.`false_result`, 
`toxicology_toxicologyqualitativetestreference`.`true_outcome`, 
`toxicology_toxicologyqualitativetestreference`.`false_outcome`, 
`toxicology_toxicologyqualitativetestreference`.`concentration`, 
`toxicology_toxicologyqualitativetestreference`.`cutoff`, 
`toxicology_toxicologyqualitativetestreference`.`units`, 
`toxicology_toxicologyqualitativetestreference`.`method`, 
`toxicology_toxicologyqualitativetestreference`.`description` FROM 
`toxicology_toxicologycasequalitativeresult` INNER JOIN 
`toxicology_toxicologyqualitativetestreference` ON (
`toxicology_toxicologycasequalitativeresult`.`test_id` = 
`toxicology_toxicologyqualitativetestreference`.`id`) WHERE 
`toxicology_toxicologycasequalitativeresult`.`case_id` = 239 ORDER BY 
`field_sql` ASC

The second method generates this SQL:
SELECT `toxicology_toxicologycasequalitativeresult`.`id`, 
`toxicology_toxicologycasequalitativeresult`.`case_id`, 
`toxicology_toxicologycasequalitativeresult`.`test_id`, 
`toxicology_toxicologycasequalitativeresult`.`detection`, 
`toxicology_toxicologycasequalitativeresult`.`result`, 
`toxicology_toxicologycasequalitativeresult`.`concentration`,

Hi,

you may need to install sqlite3 for windows and set your PATH to the

channels working in runserver but "Still in CONNECTING state" then "ERR_CONNECTION_TIMED_OUT" in production

2017-10-30 Thread Adam


Hello,

I am following "getting started" in the django channel docs as well as 
"django channels form the ground up" 
https://artandlogic.com/2016/06/django-channels-ground-part-2/  tutorial in 
the django,  using REDIS, NGINX and GUNICORN on digital ocean. 

Based on console errors in the browser, I used this code  modified from 
modified from the docs to test the channel in my browser (JavaScript):

socket = new WebSocket("wss://" + window.location.host + ":8001/chat");

Then the rest is copied directly:

socket.onopen = function() {
socket.send("hello world");
}

// Call onopen directly if socket is already open
if (socket.readyState == WebSocket.OPEN) socket.onopen();

 As the title states, the JavaScript test works on the run server -   
python manage.py runserver 0.0.0.0:8000 but not o the production server.

Here is the terminal response to the run server command:

Performing system checks...

Ok, i finally found where the problem was : the admin class (UserAdmin) of 
my custom user class was in models.py and must be in admin.py.

I found the solution here :

TruncHour with tzinfo throws AmbiguousTimeError

2017-10-30 Thread Vincent T.

I have a model with a datetime field that is filled with UTC datetime 
values (time_aware)

I am trying to aggregate data by hours on another timezone 
('Europe/Paris'). Last sunday at 2am there has been the day-saving-time 
impact to local time.

pytz.exceptions.AmbiguousTimeError: 2017-10-29 02:00:00

The problem is that there is no way to tell django that is_dst is True

here is my query:

additional_data = query \

.annotate(

hour=TruncHour(

'datetime',

tzinfo=pytz.timezone(thermostat.structure.timezone),

output_field=DateTimeField())) \

.values('hour') \

.annotate(

heat=Avg(Case(When(heating=True, then=1), default=0), 
output_field=FloatField()),

cool=Avg(Case(When(cooling=True, then=1), default=0), 
output_field=FloatField())) \

.values(

'hour',

'heat',

'cool')


Do you have some ideas how I could workaround this issue?

Yes, there is my INSTALLED_APPS (it was ok with Django 1.10) :

INSTALLED_APPS = [
#django
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.sites',
'django.contrib.flatpages',
'django.contrib.humanize',
#third-parties

'emoticons',
'form_utils',
'mathfilters',

'blog',
'challenge',
'core',
'django_resource',
'files',
'help',
'mailing',
'questionnaire',

And later :

AUTH_USER_MODEL = 'authex.UserProfile'


Thanks for helping. :)

Re: MultipleChoiceField records down choices as a list, but CharField converts them to a list?

Given your model definition, that means that a Python list object was
converted to a string and stored in a single database field, which means
that you no longer have a list, you have a Python string that looks like a
list.

If your model can have multiple values associated to a single object for a
single field, consider a M2M relationship with a table containing all of
the available options.

This is slightly confusing. Is 'model' a context variable that you are
providing in your view? I'm assuming this refers to the object being pulled
from the DB. If that's the case, then this code is roughly equivalent to
the following:

for x in "['Condo ap'":
print(x)

You likely just need {{ model.property_type }} given your model definition.

Happens a lot in templates when they go too deep with the {% for %} tags.

I think you're intermixing Model fields and Form fields, both of which have
very different functions. I did the same thing when I first started with
Django:

https://docs.djangoproject.com/en/1.11/ref/models/fields/
https://docs.djangoproject.com/en/1.11/ref/forms/fields/

These are not interchangeable as they have different purposes.

It's not necessarily clear what you are trying to do. Your template code
indicates one thing, and your textual description another.

According to your template code, you are simply displaying a static
unordered list of text blurbs on the page, no form elements involved. From
your other descriptions,  you are trying to display a select form control
with multiple options in it. A bit more guidance here would result in a
better answer.
