Specify method at as_view in Django urls. (GET, POST etc)
I have some classes with (APIView) and obviously I include them in my urls.py. Question is, if there is a way, to specify method, when I use construction like that: path('mods/mix', MixCUD.as_view()), path('mods/mix/update/<int:mixId>', MixCUD.as_view()), path('mods/mix/delete/<int:mixId>', MixCUD.as_view()), Because, if I understand correctly, I can call delete method of a MixCUD from mods/mix/update/int:mixId address. So I need something like that: path('mods/mix', MixCUD.as_view([POST])), path('mods/mix/update/<int:mixId>', MixCUD.as_view([UPDATE])), path('mods/mix/delete/<int:mixId>', MixCUD.as_view([DELETE])), I can't change them all to a single address, so I have to manage this somehow. -
uwsgi not loading webpacks bundle files (.js)
I'm having a hard time with uwsgi. What happens is (I assume) uwsgi fails to attach main.js in index.html which Django routes. main.js is a webpack bundle from npm run build. My application runs in docker and in it I specified /vol/web/static/frontend directory to include main.js and it is there. curl 127.0.0.1:8000 gives me html (as expected), but in Mozilla, on same socket I get a blank page (with 200 OK http request and response of below html). At 127.0.0.1:8000/static/main.js I receive this main.js file. Why do I get a blank page ? Any clues ? My effort on this is I've reworked my whole static files rooting and directories in Django, tried a 1000 different flags on uwsgi cmd and different static files directories and paths to load from. None of this worked for now.

Django Admin: Give initial data to form field
I need to manually add an entry to the database via the admin panel, but the admin should not be able to set all the values: #models.py class Product(models.Model): price = models.DecimalField("price") status = models.PositiveIntegerField("status") name = models.CharField("name", max_length=31, unique=True) ## tried: def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.initial['status'] = 2 #admin.py class ProductForm(forms.ModelForm): class Meta: model = Product fields = ["price", "name",] @admin.register(Product) class ProductAdmin(admin.ModelAdmin): form = ProductForm ## tried: def get_changeform_initial_data(self, request): return {'status': 99} Admin should be able to create a Product and give it a name and price, but the status value should be set to 0. I already tried this approach and this, but no success. I tried: Using an __init__ method to add initial values get_changeform_initial_data() method to add a status.

User to paying registration fee for Django application

Multiply every form value in Django template
I'm created a form where values are coming from my view and the value is daily basis and I want to give a drop down where user can change it to weekly basis and the values will be multiplied by 7. As you can see in the above picture, I'm giving a drop down option where user can change it to weekly basis and monthly basis and the value inside the form will change as per the selection. But I'm not aware how I can achieve this. My code: return render(request, 'test.html', {'List1': l1, 'List2': l2, 'List3': l3} and my form.html is readonly form which renders these list in order. <form> <div class="form-row"> {% for l in List1 %} <div class="form-group col-md-4"> <label>x</label> <div class="input-group mb-3"> <input type="text" value="{{l}}" readonly> </div> </div> {% endfor %} </div> ........simliary for rest list. </form> I want to multiply every value inside form by 7 when user selects weekly in drop-down. How can I achieve it? -
Django + MQTT how to make request and wait for response in view
I am writing a django application and I need a way how to ask for data on MQTT and wait for response (or timeout). Something like this in view: mqtt.subscribe('response/topic') mqtt.publish('request/topic', '{my json request message}') for m in mqtt.on_message(): if m.payload == '......' # OK I have response, render data from response to page, ... # timeout could be implemented by raising exception in on_message() How can i integrate paho mqtt? Or is there any other way? I need to wait for response on several places in views, one global on_message callback is not really useful. Where should I put mqtt.loop_forever() in django? Thank you -
Django multi-app static files - developing locally and pushing to Elastic Beanstalk server
I have a django project with multiple apps inside it as so: /UserProject /Static /UserApp /UserApp/Static I have my global styling held within the /static/ folder, then individual UserApp styling held within the UserApp static folder. Then, within my settings.py I have: STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) This is great for local development - I can run the development server and the site updates as I update the stylesheets within either the root /static or the UserApp /static. However, when I push to my elastic beanstalk instance (depending on my configuration) - I get either (a) only the root /static files loading, (b) no static files loading or (c) an error on deployment You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path. I have tried using the following in my .ebextensions folder container_commands: 03_collectstatic: command: "source /opt/python/run/venv/bin/activate && python manage.py collectstatic --noinput" But this gives me the staticfiles app error. What is the correct setup in my settings.py to allow local development, and then also allow pushing to the EB instance? -

Django foreign key: auto-lookup related object when the update record has the key value
I have legacy code which had no foreign keys defined in the schema. The raw data for the row includes the key value of the parent, naturally. My first porting attempt to postgresql just updated the field with the raw value: I did not add foreign keys to Django's models. Now I am trying to add foreign keys to make the schema more informative. When I add a foreign key, django's update requires me to provide an instance of the parent object: I can no longer update by simply providing the key value. But this is onerous because now I need to include in my code knowledge of all the relations to go and fetch related objects, and have specific update calls per model. This seems crazy to me, at least starting from where I am, so I feel like I am really missing something. Currently, the update code just pushes rows in blissful ignorance. The update code is generic for tables, which is easy when there are no relations. Django's model data means that I can find the related object dynamically for any given model, and doing this means I can still keep very abstracted table update logic. So … -

How to get html form field data in JSON and insert into database with Django?
I have created one project where User Registration functionality is there. Once user fill the form, I'll be getting data in Django using POST and insert into Database.
