django - testing a django-admin command using mock

twitter developer api oauth gives bad authentication data, but all good
Trying to get Twitter to authenticate my get request to the new api for recent tweets around a particular topic. I have some issues with the authentication, that I can't seem to pin down. I authenticated my application using a client key and client secret, then authenticated a user and accepted that the app can read and write permissions. With the users authentication token and secret I tried to authenticate to get the data from the newish api and got bad authentication error.

Python-Django-Template and PHP Integration: why not?
Title. I have a project coded in Python using Django as the framework, as well as using Python Django-templates for the frontend for a business. I'm planning to integrate a payment system into it and from what I've seen, most of them are coded in PHP. I've already built a sort of checkout screen using the Django-template that could still slot in the payment screen before finalizing the transaction of the product. (I'm still researching on whether this is the best implementation, or whether I should do alot of redirections) As a PHP newbie, naturally I started researching on how do I go about implementing this(as I dont even know where to start). I came across ('refer to the FAQ on the linked site which LOLs at the idea') a ('it's a terrible idea') few ('it's an awful idea') topics ('Please do not encourage anyone to use PHP inside Django, this is wrong on so many levels') that discourages PHP and Django use. The one thing in common is that none of those ever explain why exactly is it a bad idea... Why? -

Solr and Haystack autocomplete with spaces
I am trying to get an autocomplete / auto-suggest function working, and have encountered a problem with Haystack (latest master) and Solr (6.6.6). I am using Haystack's autocomplete() function, which requires the indexed field to be an EdgeNgram (or Ngram). The autocomplete queries work fine until I have a space and start the beginning of a second word. For example: "st" yields ["Star Wars", "Starlight Express"...] "wa" yields ["Star Wars", "Waterworld"...] "star" yields ["Star Wars", "Starlight Express"...] However, as soon as I get to a space and the start of a second word I get no results: "star w" yields no results From my investigations so far this seems to be because Haystack is converting the two word phrase into an AND based two word query. "star AND w", or (AND: ('title', 'star'), ('title', 'w')). The combination of the AND operator and the second query term "w", which is not a valid stem, means that no results are returned. I could override Haystacks autocomplete to use the OR operator to partially fix this... But, is there a better approach / solution? Ideally I would like the search for "star w" to return "star wars" (and not all films starting with … -
Django/Python Guidance
I am trying to build an e-commerce website using Django, most specifically with the Django-Shop package and I am having some troubles along the way, and I just thought that if I could find a mentor or somebody to help me during the way would be the perfect way for me to learn more and be able to finish the project. And I am willing to pay for that, so if you already used Django-shop for some project or are confident about helping me to build an e-commerce website with normal Django I would be more than happy to work with you. So that you know where I got stuck now, I simply cannot make a new product type based on the BaseProduct model that I have, it seems like a very good idea to kickstart the project using the Django-shop package, but it is very hard to understand it as a whole since there is a lot of code on it already. -
<class ‘decimal.ConversionSyntax’> errors when importing data from a CSV file using Python (tried using CSV and Pandas)
I have a CSV file from a small business that represents their records for about 70,000 orders spread out over about 30 years. My goal is to store this data in a Django project with a DecimalField in the model setup to receive the import. Before trying to store the data in Django I'm first trying to import this data into Python. While most of the records import fine there are about 1 in 1000 that throw off a <class 'decimal.ConversionSyntax'> error during the import. This is causing me to get incorrect data into Python. I need to either fix how it reads the data or fix the problem in the data itself. I have tried both the python csv library and pandas to open the file. I've looked at the csv file in a text editor (SublimeText) and can't find any anomalies with the way the data is stored. I have tried to convert the data to UTF-8 using Microsoft Excel I have attempted to copy the data out of Excel into SublimeText, then back from SublimeText into a new row in Excel (virgin row with no data in it beforehand). None of this has resolved the issue. How … -

Images don't get loaded in production
I am creating a website with Django and has several pictures that are added depending on what I put on the database. In order to host the website online, I used Heroku and used their PostgreSQL database for my online database. For some reason as soon as I upload the images they were there, but after some time they all disappeared. Django knows that the images exist and the URL for that image is also perfectly fine when I right-click the image and click open on a new tab. This is how my website is now... -
Python/Django/MySQL optimisation
Just a logic question really...I have a script that takes rows of data from a CSV, parses the cell values to uniform the data and makes a check on the database that a key/primary value does not exist so as to prevent duplicates! At the moment, the 1st 10-15k entries commit to the DB fairly quick but then it starts really slowing as there are more entries in the DB to check against for duplicates....by the time there are 100k rows in the DB the commit speed is about 1/sec argh... So my question, is it (pythonically) more efficient to extract and parse the data separately to the DB commit procedure (maybe in a class based script or?? Could I add multiprocessing to the csv parsing or DB commit) and is there a quicker method to check the database for duplicates if i am only cross-referencing 1 table and 1 value?? Much appreciated Kuda -

Unable to open downloaded file embedded file link in a webpage because file format or extension is not valid
My client has requested that I embed a link for a downloadable excel in my react/django site and unfortunately the download works whenever I run the site on my local, but after deployment you can successfully download the link, but whenever you open it, excel throws a popup that says "Excel cannot open the file 'filename' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file. I've checked the file in the directory of the build on GAE and the extension is still .xlsx, after the download I still see the .xlsx extension in my downloads folder. I've even tried to convert the excel to a pdf and embed that link, and while that still works on my local, after deployment I get "Failed to open file." I'm not sure if this is actually related to the deployment or some of the config settings in django or react tripping me up similar to how static images need to be specified in the app.yaml. I've searched the documentation on the subject on their site here: https://cloud.google.com/appengine/docs/flexible/python/reference/app-yaml and nothing jumps out to me …
