template drop down menu

[sum abiut]

Hi,
need some directions, i need to query the my database and display the
result of the query in the table. to do that i want to use a drop down menu
and get the users to select options from the drop menu on the template.

for example if a user select a word from the drop down menu i want to
filter and query the database base on the option that is selected and then
display the result.

I am confuse on the template side. on the template side how to i know if a
user select a particular option from the drop down before so that i can
perform query base on option that was selected from the template and
display query result base on the respective word that was select.

Cheers,

Re: Installing Django in Window 10

[Oladipupo Elegbede]

Are you sure you don't already have Django installed?

Try to import Django from your Python prompt and see what happens.

If it doesn't throw any error, you have it. If it does, you can do

pip install Django

That should install it.

Ah, yes. This is the other common issue with the tutorial. Many of the code
blocks omit the necessary import statements to keep the examples easier to
read. The expectation is that the reader has at least a basic understanding
of Python and how it references other libraries. Admittedly, they are easy
to forget.

I'm using this is a general solution. Feel free to strike what you don't need.
The basics is that a JSONEncoder knows primitives and how to recurse

It's called Gregorian, not normal. You could use this package:

Or google it to find other solutions.

Re: Authentication backend - serialization

[ludovic coues]

I don't see where in your code the error happen.

With standard python, you can't add a method on your class to make is
JSON serializable. At least to my knowledge. You have to write your
own serializer and instruct the code turning your object into JSON to
use it.

But there are a few easier alternative. For example, model_to_dict (
https://docs.djangoproject.com/en/1.11/_modules/django/forms/models/
). This function will take your model, a list of field then build a
dict. As long as you are not using fancy fields like a DateTimeField,
the dict should be JSON serializable.

Re: django-channels with django-tenant-schemas

[Andrew Godwin]

Does the WebSocket handshake finish? The developer console in a browser
should tell you if it actually opens up or not.

Normal Django middleware shouldn't affect WebSockets as it's a different
networking style, but it's very easy to get WebSockets set up wrong for a
variety of other reasons.

Re: Fetching API data in json format and inserting it into the django local database.

[MOEGAMMAT FAIEEZ WHITE]

I want to get the values and store it. im creating a visualization web 
application for a data collection application which stores the data 
directly to the database.

i am doing the application as a honours project, the data collection 
application is mostly used in under-served communities, and i want to 
provide a free application that allows the admin user to visualize( in the 
form of graphs and charts) the data in their forms. 

another question, is there an option to create a form that is dynamic? for 
example different forms will have different fields.

Re: Installing Django

[Oladipupo Elegbede]

For the Python prompt from CMD and do the following

>>>import Django
>>>Django.VERSION


This should tell you what version of Django you have.

Hi Jani,

i have direct access to the database where the form is stored. I GET 
the data using the imported requests e,g [r = requests.get(url,

So your remote database contains some kind of a form that you want to 
copy to Django database and then represent that form to end user?




so the user would have to input his/her user name and password , and 
the project name for which they want the forms for. i then create a 
model with only certain key value pairs i want from the database..


my main problem is the models.py and the database insertion of the forms.



If it's simple key and value pairs doing that isn't much to code, just 
add two fields that fullfil your requirement.


also i have a python script which fetches my data, i do not know how 
to use views.py to do it.




Same way as in your script, unless fetch is really slow when you need to 
think of asynchronous alternatives.

Secondly you need to decide how to actually fetch that data from

Through RESTful API? Direct access to database? Some proprietary API?

Finally you need to have models and do necessary data
transformations to add data to your local Django database.

But it's not a rocket science. Once you know answers, there are
several tools that can help you to achieve your goal easier.

Re: Fetching API data in json format and inserting it into the django local database.

Hi Jani,

i have direct access to the database where the form is stored. I GET the 
data using the imported requests e,g [r = requests.get(url, 
auth=HTTPBasicAuth('username', 'password'))]

so the user would have to input his/her user name and password , and the 
project name for which they want the forms for. i then create a model with 
only certain key value pairs i want from the database..

my main problem is the models.py and the database insertion of the forms.

also i have a python script which fetches my data, i do not know how to use 
views.py to do it.

Thank you in advance..

Re: Fetching API data in json format and inserting it into the django local database.

[MOEGAMMAT FAIEEZ WHITE]

Hi Jani,

i have direct access to the database where the form is stored. I GET the 
data using the imported requests e,g [r = requests.get(url, 
auth=HTTPBasicAuth('username', 'password'))]

so the user would have to input his/her user name and password , and the 
project name for which they want the forms for. i then create a model with 
only certain key value pairs i want from the database..

my main problem is the models.py and the database insertion of the forms.

also i have a python script which fetches my data, i do not know how to use 
views.py to do it.

Thank you in advance..
Faieez

Solve what? It's telling you Django is already installed.

Re: Fetching API data in json format and inserting it into the django local database.

[Jani Tiainen]

Hi,

First you need to decide how you are going to activate fetch data from 
remote company database.


Is it a button in user interface, django management commant or maybe 
timed task?


Secondly you need to decide how to actually fetch that data from remote 
company database


Through RESTful API? Direct access to database? Some proprietary API?

Finally you need to have models and do necessary data transformations to 
add data to your local Django database.


But it's not a rocket science. Once you know answers, there are several 
tools that can help you to achieve your goal easier.

Authentication backend - serialization

[Alison P]

Hi everyone,

I have written a custom authentication backend, the code is below. It 
allows a user to click "email me a one-time password" on the home page, 
which is saved on the "Person" model (which extends User through a foreign 
key) and then log in with that password. This backend verifies the password 
and then erases it from the database. 
This whole thing works when I put 
SESSION_SERIALIZER='django.contrib.sessions.serializers.PickleSerializer' 
in settings.py, but I don't want that since PickleSerializer is unsafe. 

If I use the default session serializer, I get the following error: 
TypeError at /login/ 

 is not JSON serializable


how do I solve this? Do I need to write a custom serializer, and if yes, 
how? Can I add serialize/deserialize methods on this class, and what 
exactly do they need to do? Do they need to be classmethods or something?

I would really appreciate some help with this. Thanks in advance!

from django.contrib.auth.models import User
from allauth.account.models import EmailAddress
from passlib.hash import pbkdf2_sha256
from api import models
from base.settings import ACCOUNT_PASSWORD_MIN_LENGTH

class OneTimePasswordBackend(object):
def authenticate(self, email=None, one_time_password=None):
if len(one_time_password) < ACCOUNT_PASSWORD_MIN_LENGTH or 
one_time_password==None:
return None
try:
email_obj = EmailAddress.objects.get(email=email)
except EmailAddress.DoesNotExist:
return None
user = email_obj.user
person = models.Person.objects.get(user_account=user)
saved_pw = person.one_time_password
try:
verify = pbkdf2_sha256.verify(one_time_password, saved_pw)
except Exception as e:
print(e)
verify = False
else:
"""reset the one time password"""
person.one_time_password = ""
person.save()
return user
return None

def get_user(self, user_id):
try:
return User.objects.get(pk=user_id)
except User.DoesNotExist:
return None
