QUESTION
In my viewset, I have given filterset_fields to query the model through an API endpoint. I want to convert the retrieved queryset to a dataframe for processing the data in the model using pandas. For this, I used the django-pandas
's to_dataframe()
method.
Following are the Viewset and the function used in the viewset:
...ANSWER
Answered 2021-Feb-17 at 09:13You use self.queryset
in your method which you have set to StockPriceData.objects.all()
, and do no filtering or pagination on that. Change your method to do those tasks:

On my MacBook (version 10.14.6) I am succesfully running a Django application including TensorFlow and tf-sentencepiece (in particular to use the universal sentence encoder model). When I perform a pipenv lock -r > requirements.txt
I get the following required packages:
ANSWER
Answered 2020-Jan-09 at 09:54I have no skills in Django, but it seems that tensorflow is trying to find a package (with a strange name) and failing.
I'd first suggest to try and fix your docker container setup, and check that pipenv lock -r
yield the same result inside and outside your container.
1) as you said in the commentaries, on the host pc

I am trying to install requirements.txt of a django project and it is giving me the following error:
MySQLdb/_mysql.c(29): fatal error C1083: Cannot open include file: 'mysql.h': No such file or directory

...ANSWER
Answered 2019-Nov-12 at 07:52The problem is you're using a 32-bit version of Python 3.6, for which there aren't wheels (binary versions) for that version of mysqlclient.
You can see here in the package file list that there is a Windows x32 wheel for 1.3.12 – try that.
QUESTION
I am trying to accomplish the following workflow in my Django project:
- Query my database
- Convert the returned queryset to a pandas dataframe in order to perform some calculations & filtering
- Pass the final dataframe to Django REST API Framework
if I understand correctly, I have to use django-pandas for Step 2. and Django REST Pandas for Step 3. I installed both and read the documentaton, but I have no clue how to make it work.
What I have achieved to far is to set up my model, views, serializes and urls to have the original queryset rendered via the Django Rest Framework.
If anyone could give me a hint on how to integrate pandas in this workflow, it would be highly appreciated.
my models.py file
...ANSWER
Answered 2019-Oct-30 at 08:15So i figured it out. First, you need to install django-pandas and django rest framework (but no need to install django REST pandas)
models.py and serializers.py files stay the same as above, but the views file is different
QUESTION
Hi guys I have a problem: I've made my first Django App extensively using pandas in my views.py to load csvs, make some data prep and loading my pickle ML model.
The problem is that all this was working fine until I tested on the deployed app (using nginx and uwsgi) where I got an error No Module named pandas
which, researching seems to be a very common issue due to the fact that Django doesn't allow importing pandas directly.
I saw some Django-pandas frameworks but their documentation is quite cryptic to me.
Can you explain me in a simple way How can I execute those functions in pandas using Django (even with the help of a Django-pandas framework):
...ANSWER
Answered 2019-Jul-30 at 09:37It seems like either you are using virtualenv and pandas seems to be not installed in it or there is conflict in python versions being used.
Have you seen https://www.reddit.com/r/learnpython/comments/9gflmo/import_error_no_module_named_pandas_even_though/ ?
django-pandas is primarily used to interchange django model values to dataframes. I see no reason why pandas should be causing any problems in general.
QUESTION
I have the following dataframe that was created from a Django queryset using Django-Pandas. I think this is important because I can't find a way to set the column index on conversion.
...ANSWER
Answered 2018-Jun-18 at 05:35You'll need pivot_table
(or pivot
) and then a little housekeeping to reorder the axes and levels.

Inheriting from this question which wasn't completed to a workable code solution from what I can tell.
I'm trying to get a very simple wenzhixin/bootstrap-table
to work. I can print the columns
and data
objects to the console - so they work. Here are the code snippets:
ANSWER
Answered 2018-Jun-17 at 06:03After stripping everything down to a bare minimum code - it was clear that the issue is the load order of js

files. The order needs to be global files first, local files second.

QUESTION
I am using django-restframework,pandas,django-pandas to make an api and i am getting the following output
This is the data of a single user and each label represents a column name but I want the output in the following format
can anyone help to get the data in the desired format
My code is
views.py
...ANSWER
Answered 2017-Mar-29 at 13:06This is happening because a
is a pandas.DataFrame
and it corresponds to table, so during serialization it tries to represent all data for each table column. DataFrame
does not know that you have only one value for each column.
Values have to be extracted manually:

Install django-pandas
You can use django-pandas like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
