Sending array of texts to Django, via POST, cannot get as array, getting string

Question

I'm sending this data to Django, these texts are from multiple CKEditors

chk_vals = ["Some text","Other text"];
const data = new URLSearchParams();
data.append("csrfmiddlewaretoken", "{{csrf_token}}");
data.append("tmplData", JSON.stringify(chk_vals));

fetch(uri, {
        method: 'post',
        body: data,
    })
    .then(response => response.json())
    .then(data => {

It's from Chrome's network: tmplData: ["Some text","Other text"]

Now Django:

data = request.POST
templateArr = data.getlist('tmplData')
templateList = list(templateArr)

And the length of the templateList is 1, it is getting it as one string and I cannot split it with ',' because these texts can contain ',' too.

I also tried templateArr = data.getlist('tmplData[]')

and sending without JSON.stringify, but nothing works

data = request.POST
templateArr = data.getlist('tmplData[]')
templateList = list(templateArr)

and this variable templateArr is empty

Try sending values from frontend as individual fields like below:

chk_vals = ["Some text", "Other text"];
const data = new URLSearchParams();
data.append("csrfmiddlewaretoken", "{{csrf_token}}");
chk_vals.forEach(value => data.append("tmplData", value));
fetch(uri, {
    method: 'POST',
    body: data,
})
.then(response => response.json())
.then(data => console.log(data));

And then try accessing it via your Django backend like below:

templateArr = request.POST.getlist('tmplData') # templateArr = ["Some text", "Other text"]
