Re: RelatedObjectDoesNotExist: User has no vendor

coming because of `vendor = request.user.vendor`
you have attached user to vendor so you can access user from vendor by doing
`user = vendor.created_by` but you can not access vendor from user

Re: Using ORM to retrieve values (REAL) from SQLite database to round to 2 decimal places

[Lalit Suthar]

That's great the way you found the workaround :D

We can also try writing raw sql queries to use sql functions
https://docs.djangoproject.com/en/2.2/topics/db/sql/#executing-custom-sql-directly
But that has some security issues since we have to pass a search parameter
into it.

Re: help on autologging users after signup

[lalit suthar]

It is not returning the "login success" message because you are using 
`APIView` parent class and that does not have create() method so your code 
inside create() won't get executed. You have to move that code to post() 
method. https://www.cdrf.co/ is a good reference to find out different 
Parent class's and their supported methods.

Re: CSS not linking with HTML

[lalit suthar]

read this https://docs.djangoproject.com/en/2.2/intro/tutorial06/ and check 
how you are giving paths. Also after loading the page on your browser go to 
"View Page Source" and click on the CSS file link and check if the file is 
opening or not.

Hi there! 
make these couple of changes 

1) from django.core.serializers.json import DjangoJSONEncoder 
2) dump3 = json.dumps(chart3, cls=DjangoJSONEncoder)

in different format then the chart is expecting.
What are you using for drawing the chart? can I see the code inside
"summarizedchart.html"

Re: use of annotate in django query

not sure but maybe this can work inside views replace
chart = {
  'chart': {'type': 'column'},
  'title': {'text': 'Previous statistics'},
  'xAxis': {'replist': replist},
  'series': [arriva_days]
}
with
chart = {
  'chart': {'type': 'column'},
  'title': {'text': 'Previous statistics'},
  'xAxis': {'categories': replist},
  'series': [arriva_days]
}

Re: Support for moving a model between two Django apps #24686

[lalit suthar]

We had a similar problem and we resolved it by moving all the models into a 
separate internal python package. 
We can have a separate app in our django project also for writing models 
only and all other apps import models from there.

Re: ProgrammingError - relationship does not exist

you can try this

if that also doesn't work and you are working on a personal project then
you can try deleting your db, migration files and re running migrations

Re: Help

[Lalit Suthar]

You should send a custom frontend url to the users, appending the
parameters required.
Now your frontend will received that and send a POST request with the
params received to your DRF backend
There you can verify the parameters and change the password

Re: cannot get value(foreign key) after using distinct()

since you are using .first() in the query, it will return only 1 object so
I don't think using a for loop our 'category' in template will work

Re: Modeform Foreign key column not working

is `ConnectionTypes` a foreign key to `ConnectionDetails`?
in that case you don't need to put it as a field in form, it will be added 
automatically in the form.

Sum, Count works when we try to get sum/count for a column,
for this case you can try something like this

count = 0
for val in user.__dict__.values():
if val == "YES":
count += 1
return count

Re: Use previously requested data in another request

[Lalit Suthar]

We can save that in any django model in ajax() request if possible.

You can check if you have modified `SESSION_COOKIE_AGE` (
https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-SESSION_COOKIE_AGE
)
if it is too less that might be the reason.

Re: Exported filtered by date data in django

[Lalit Suthar]

`filter_val1` and `filter_val2` are coming from POST request so they are in
`string` format.
But the `created_at` field of the `EXPENSES` table is in `datetime` format.
This is why the result of the filter() is coming as empty.

The query will run fine when the 2 values compared are in the same format
of data.
Same like we can not add 3 apples and 2 bananas.

Convert the `filter_val1` and `filter_val2` in datetime before passing them
in the query.
Refer:
https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior

Re: Handling url in class based views.

[Lalit Suthar]

you can get that slug value from kwargs

def get(self, request, *args, **kwargs):
slug = self.kwargs.get("slug")

also if you like to pass it in the context you can override get_context_data

refer: https://ccbv.co.uk/
to know more about class based views you can refer to this playlist from
video number 36

Re: Multiple Templates in single list view

[Lalit Suthar]

we can go like

```

class Manager(...):
def get_context_data(self, **kwargs):
context = super() 
context["open_tickets"] = Ticket.objects.filter(status="OPEN")
context["accepted_tickets"] = Ticket.objects.filter(status="ACCEPTED")
context["completed_tickets"] = Ticket.objects.filter(status="COMPLETED")
return context
```

Re: Re-write an application from Turbogear to Django.

in the database and once all the apis are ready. We can easily pick React
part.

 Every time i try running it on the command prompt, i get relocated to 
 my visual studio of manage.py file that states this:

 #*!/usr/bin/env python*
 *"""Django's command-line utility for administrative tasks."""*
 *import os*
 *import sys*


 *def main():*

 *"forget to activate a virtual environment?"*
 *) from exc*
 *execute_from_command_line(sys.argv)*


 *if __name__ == '__main__':*

 A step in the right direction will be super helpful for me.

Re: order_by on the basis of time difference (updated_at - created_at)

[Lalit Suthar]

won't be possible like this, It will be easy if you have another entry in
models which stores the difference between updated and created.
You can update that field whenever an object is updated. And then can run
order_by on that field directly

Re: Negated filtering by lookup expression sent via url query

[Lalit Suthar]

you can write custom filtering classes and methods using Django filters.
There you can define fields and methods according to your use case
example:

Re: Best approach for audit logging in Django.

[Lalit Suthar]

Hi Sencer, signals will be helpful only if you are auditing on certain
models
but if you are trying to audit a set of views then middleware will be a
better choice since that will be more manageable

Re: DRF question

[Lalit Suthar]

I would also suggest keeping Django views as it is and writing new views
for your APIs
maybe you can create another file named apiviews.py and then write new APIs
with help of your present views
refer: https://www.django-rest-framework.org/api-guide/views/
