Django class-based view processing form and adjusting context accordingly
I'm pretty new to Django and Python in general. I am building a Django app at the moment and am trying to stick to class-based views. I have a form (FormView) that I would like process, meaning take the data, clean it up and store it in the database. When processed I'd simply like to show the form again (so no redirect to another success page) and show the result of the processing above the form. How would I do that? I have played around with get_context_data to add the additional context for the result message but can't figure out how and where to process the data and how to tie it together with updating the context data then. Any help would be appreciated. forms.py: from django import forms class URLsForm(forms.Form): list_of_urls = forms.CharField(label='One URL per line', widget=forms.Textarea) views.py from django.views.generic import FormView from .models import URL from .forms import URLsForm class URLBatchCreateView(FormView): form_class = URLsForm template_name = 'bot/url_batch_create.html' success_url = reverse_lazy('url_batch_create') def form_valid(self, form): return super(URLBatchCreateView, self).form_valid(form) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['created_urls'] = 'The result' return context url_batch_create.html: {% extends 'bot/base.html' %} {% block content %} {% if created_urls %} <div>The following URLs where created:<br>{{ created_urls }}</div> … -

How to replace string in django model query
I want to replace a string in a django model query result. my model: class director(models.Model): direction = models.CharField(max_length=100) name = models.CharField(max_length=100) The content of the direction field is either "U", "D", "L" or "R". How do I make a query so that when I select the field direction, I get "Up", "Down", "Left", "Right" respectively. I can achieve this in SQL with: SELECT replace(replace(replace(replace(direction, "U", "Up"),"D", "Down"),"L", "Left"),"R", "Right) as direction from director or using CASE WHEN in in SQL. I know I can achieve this using for loop in python after director.objects.all() but I was hoping that I can do this in the query itself -

How to stream the contents of a log file in Django as a web-page

Best way to define reusable blocks for streamfields
I'm planning on building large portions of my page templates with streamfields, using blocks that will be reused across page models. What's the best way to implement this so I can reuse my code across models, and leave only 1 place to update if I want to change the block or the way it renders? I'm envisioning basically building a library of streamfield block definitions, then selecting the applicable ones for a given field in a given model. Should I just go with a generic python library and include it and reference it in my page models, or use abstract Django models or something else? I think trying to make the actual instances of the blocks reusable within the page admin will be overkill (and over my head), but would be open to that as well. -

django-modeltranslation: how to disable showing objects (e.g. posts) the languages where it is not defined?
I am developing a django multilingual app and using django-modeltranslation to translate the models. It works fine except one thing: when translation is not available in a specific language, it still shows the objects (let's say posts). I have some posts that are available in tajik while not available in russian, and vice versa. My goal is to disable showing the posts in the language which I do not have translation.

Is there any difference Dockering fullstack Django vs. Django Rest framework application?
There are many instructions for rest framework dockering, but is it similar to normal django with templates (=html pages) ? Also I use mongodb atlas cloud db with djongo. It works locally, but will it work with dockerized django app? Reason why Im dockering is that any app service I have tried doesn´t accept mongo with django the same way as it works locally. -
Django-React/Redux-Apache project: Can't resolve url
first time building a web app. decided to use django/react with redux and django rest framework for api routing and component state. decided to implement apache as a production server and test locally. when I used the django development server everything worked fine but when I switched to apache I hit an issue. I can get the static content to display at the root url "http://localhost" but can't get any further urls to resolve. On the main page of this app there's a component that, when it mounts, calls a url (GET) ".../api/buildings" to populate the component with some data but the server responds with a 404 or 500 but didn't when I used django dev server. I can't figure out what I'm doing wrong and seeing as I'm pretty new to this I'd appreciate some help! here's some code references and lmk if I can provide anything else. thanks in advance! building component that makes the call during mount: export class Buildings extends Component { static propTypes = { buildings: PropTypes.array.isRequired, getBuildings: PropTypes.func.isRequired, deleteBuildings: PropTypes.func.isRequired, }; componentDidMount() { this.props.getBuildings(); }; render() { return ( <Fragment> <h2>Buildings</h2> <table className="table table-striped"> <thead> <tr> <th>Id</th> <th>Name</th> <th>Code</th> <th>Last_Inspection</th> <th /> </tr> </thead> … -

Django: How to add to an ArrayField?

It's clear you can treat it like a regular field and do things like my_array_field = [] my_array_field.save() But what's confusing is I'm seeing everyone mention my_array_field.append("something") in StackOverflow questions. This isn't mentioned in the documentation at all. Moreover, if an arrayfield is .append()ed to, does it still require .save()? -
How to implement such a custom rollback in Django or DRF?
Out system accesses to a middle platform(I do not know how to call it in English, we call it 中台 in Chinese) which is for authentication like logging in, JWT verifying, etc. Then, We have encoutered questions when it is neccessary to rollback actions because of unexpected program errors. Like code below, the program will crash when running at 1 / 0, then AdminPermission.objects.create can be rolled back, but do_user_actions can not, cause it is a RPC function. So, we need to override transaction.atomic or something like this to implement our requirements. But, I do not know how to implement it. Pls give me some suggestions or sample code. Thx a lot. @transaction.atomic # can not rollback remote func call `do_user_actions` def create(self, request, *args, **kwargs): # call a remote func here to create a admin account. user_dict = do_user_actions(query_kwargs=query_kwargs, action='create-admin') user_id = user_dict.get('id') permission_code = 'base_permission' AdminPermission.objects.create(user_id=user_id, permission_code=permission_code) # some unexpected errors, like: 1 / 0 return Response('success') -

Django - how to encode URL parameters with forward slash only once in template?
I am having a very specific issue in my template when creating an anchor tag with the {% url %} templatetag. One of the parameters I pass to it can include a forward slash, and I want to encode that. However, if I use |urlencode:"" as is mentioned in the docs (https://docs.djangoproject.com/en/3.1/ref/templates/builtins), this leads to the variable being double encoded when it arrives in the view. This is what I have in the template: <a href={% url 'myapp:myview' param1=param1 paramWithSlashes=paramWithSlashes|urlencode:"" %}> Then in my view function, the variable paramWithSlashes comes in double encoded. Meaning in order to get back the original string I have to call: import urllib.parse def myView(request, param1, paramWithSlashes): originalStr = urllib.parse.unqoute(urllib.parse.unquote(paramWithSlashes)) This is a really hacky solution and I'm sure double encoding/decoding is unwise in the long run. How can I ensure the url template tag only encodes once, with '/' included in the encoding? -

Why do I get "AssertionError: May not set both `read_only` and `required`" in Django Rest Framework?
Why am I getting AssertionError: May not set both 'read_only' and 'required' when I try to access the TestViewSet?

I'd prefer not to use fields='__all__' for 2 reasons: it will result in a lot of unused data on my real serializer the channel_id column ends up being rendered as channel, which is inconvenient, and will force me to update my frontend code to reference channel, or I will have to append _id to the data. I would just create an alias on the serializer: class TestSerializer(serializers.ModelSerializer): channel_id = serializers.CharField(source='channel_id') ... but doing so results in another error... AssertionError: It is redundant to specify `source='channel_id'` on field 'CharField' in serializer 'OrderSerializer', because it is the same as the field name. …
