How do you test a django webapplication's front end when it's heavy JS?
This is more of a guidance thing. Here's the general breakdown of my app: It has a backend with all the models It has an app for the API routing and the serializers/viewsets It has a frontend that takes care of the main routing (index, contact us, content, etc.) and serves the templates and the static components Part of the static components are mustache-js templates. When the user loads the page the client performs some ajax requests to the API and pulls in data, it then takes care of populating components. I currently have tests for Backend models API behavior and methods Frontend paths actually loading But how do I test the parts where it's mostly JS dependent? I've been using selenium to do this. Is this the right approach? It does seem awfully hacky. -

Django form for writing blogs
As a beginner in Django I know how to create basic website for blogs, using a Django model of fields title and content... that's it. But now I want to create a real dynamic blog form, which can have multiple sub headings, code blocks, text blocks, and images. Or basically a blog form which can have random number of these kinds of blocks (field like code, text, image). And the user can add as many number of these blocks as required. Also these blocks (or fields) which would be the part of the blog post, should be saved in the dataset in the same order as the user created. How can I achieve this? Thanks for your time. -

Deserializing array from ajax get()
I am trying to send two arrays with ajax: var pressIdList = []; var imprintArray = []; function getPressList(){ for (i = 0; i < pressList.length; i++) { pressIdList.push(parseInt(pressList[i].getAttribute("press"))); var pr = pressList[i] var prid = pr.getAttribute("press"); var prx = pr.getAttribute("x"); var pry = pr.getAttribute("y"); var imprint = { press_id : prid, x : prx, y : pry, }; imprintArray.push(imprint); }; }; $.ajax({ method: "GET", url: endpoint, data: { "pressIdList" : pressIdList, "imprintArray" : imprintArray, }, success: function(data){ console.log(data) } }); request.GET looks like this: <QueryDict: {'pressIdList[]': ['42', '43', '44', '129', '71'], 'imprintArray[0][press_id]': ['42'], 'imprintArray[0][x]': ['2.3069764e-07'], 'imprintArray[0][y]': ['-4.4408921e-16'], 'imprintArray[0][width]': ['13.229166'], 'imprintArray[0][height]': ['13.229166'], 'imprintArray[1][press_id]': ['43'], 'imprintArray[1][x]': ['18.52083'], 'imprintArray[1][y]': ['-7.1525574e-07'], 'imprintArray[1][width]': ['13.229167'], 'imprintArray[1][height]': ['13.229167']} So i can get first array out of it with request.GET.getlist('pressIdList[]'). But how do i get the second one out. And why isn't it wrapped inside imprintArray[]:[] if i declared it as array[]? -

nested annotation with OuterRef not working

Open image file, save it as a string and convert it to base64
I am doing a Django project that needs to receive an image and store it into the database as a TextField. To accomplish that I am doing something similar to this: In my models.py: class Template(models.Model): image = models.TextField(null=True, blank=True) The equivalent code is: with open('logo.png', 'wb') as file: image = str(file.read()) Template.objects.create(id=1, image=image) Later, when I need to get back the file and convert it to base64 to insert in an HTML file, I am doing the following: import base64 from django.template import Template as DjangoTemplate from django.template import Context from weasyprint import HTML from .models import Template template = Template.objects.get(id=1) data = {'logo': base64.b64encode(str.encode(template.image)).decode('utf-8')} html_template = DjangoTemplate(template.html_code) html_content = html_template.render(Context(data))) file = open('my_file.pdf', 'wb') file.write(HTML(string=html_content, encoding='utf8').write_pdf()) file.close() But the problem is that the image is not showing in the pdf file. I've also tried to copy the decoded data and open it with another site, but I got a broken file. How can I fix my code to convert the image properly? -
