Django ModelForm. Select a valid choice. That choice is not one of the valid choices
I have a Model and a ModelForm. The ModelForm has a dependent dropdown list implemented with JQuery. Whenever I try to save the ModelForm in my views, I get an error saying that the choice that I have selected is not valid.

Django Rest Framework - Envelope a Paginated Response
I want to wrap an paginated response in an envelope.

Define FileField upload_to directory in Django model

Django raw sql insert query in triple quotation: Django interprets null values from ajax request data as None column
I am working on a Django/React project. Using DRF, I am throwing an API route for performing SQL queries in my PostgreSQL database. But I am having issues with my current code setup. I have setup my INSERT query in the API as raw queries (using cursor) enclosed in a triple quote multi-line string """INSERT...""", then format my values using string formatting %s. In my API, I capture each request body into a variable. Everything works fine if all request data are filled. But, if it is null, Django obviously assigns None to the variable. Now back to my sql query, Django will treat the null %s as None and as a table column instead of a correct null value, thus throwing a ProgrammingError column "none" does not exist. Here are sample codes: React Frontend const [lastName, setLastName] = useState('') const [firstName, setFirstName] = useState('') const [middleName, setMiddleName] = useState('') const [nameExtn, setNameExtn] = useState('') const [sex, setSex] = useState('') const [civilStatus, setCivilStatus] = useState('') const [bloodType, setBloodType] = useState('') const [height, setHeight] = useState('') const [weight, setWeight] = useState('') const newPersonalInfo = (token, data) => { let endpoint = "/jobnet/api/profile/pds/basic/personal/" let lookupOptions = { method: "POST", headers: { 'Content-Type': … -

Django: Where to go from "pinax.notifications?"
With regards to a deployed web-site I am rudely confronted with unexpected upgrade problems.

The Django version that this app has been running was 2.1.11 and now the latest is 3.0.4 and this seems to have caused me a boatload of problems all of the sudden. Any advice appreciated ...
