Send JSON Graph Data from Django

I’m trying to write a Django application to deal with my finances. I’ve got a nice page listing various transactions, but I thought it’d be nice to have a graph too, to see where I actually am on the spot. To do this, I’ll need two components: A JSON sender from Django A receiver and […]

Build a Django Docker Image with Cx-Oracle

TL;DR: Don’t use alpine images. There’s a glibc issue. We added a cx-oracle dependency to one of our django apps. As the previous image was just an alpine basic (python) image we needed to put in place a process to build the new image. Initially, I’ve tried to use the same alpine image (oh, the […]

DRF: What is ‘source’ in Fields?

For a couple of days I’ve been trying to de-serialise a JSON to a model. My problem is the model and the JSON have different fields, mainly to keep the model pythonic and independent of a specific JSON source. So… I’ve been trying to use the source parameter for each Field in my serialiser to […]

Timestamp to DateTime Serializer Field for DRF

I’m currently trying to deserialize JSON data to a Django model. This is quite straight forward for most numeric fields, but I have a DateTime field which is stored as a timestamp in the original JSON. At first, I thought I should read the timestamp as an integer and convert it through post-processing. Then, after […]

Save Pandas DataFrame as Django Model

TL;DR: use bulk_upload coupled with a comprehension to speed up loading. Initially, I started to convert the data frame to a Model object row by row and save it. While easy, it’s also arguably the slowest method to load records, because the save() call performs a commit. Then I looked up how to save pandas […]

You have access to blocks, include/import features, loops etc. This post is a simple exercise in loading some templates. Prerequisites I’ve been using Eclipse IDE, but you can use whatever you prefer. I’ve created a maven project and […]

Change a django password manually

The other day I’ve been confronted with a strange situation: I forgot the admin password for a django application. I was playing with installing my own pypi repository, I’ve configured and deployed a test application and, after a couple of weeks, I forgot the password. I tried several times bu I knew that I used […]

Python classes to generate CSS

A while ago I got fed up with CSS and its cumbersomeness. As my poison of choice is python, I was thinking it would be quite useful to have a bunch of classes capable of generating CSS automatically in python. One could have a base class, a set of properties, a name-value dictionary and a […]

Formless Step in FormWizard

Sometimes you’d need to show a purely informational page as part of a FormWizard. As far as I could see, there are two solutions to the problem: If the info is something like a summary, you have it available in the “success” page (the one after the wizard is finished) Alternatively, you can make it […]
