How a django channel websocket middleware can receive message
How a middleware can read all the websocket message ? From my understanding a django-channel middleware is like https://github.com/django/channels/blob/2a98606c1e0600cbae71ae1f02f31aae5d01f82d/channels/middleware.py. async def coroutine_call(self, inner_instance, scope, receive, send): """ ASGI coroutine; where we can resolve items in the scope (but you can't modify it at the top level here!) """ await inner_instance(receive, send) I know that if I call await receive() instead of await inner_instance(receive, send), I will get a websocket message, but in this case the websocket handler will not work anymore. How can a coroutine_call can receive the websocket message but also forward it to the next websocket middleware or handler ? -
Why doesn’t FloatField accept to input float value?
I’ve build a web app with Django. Although the FloatField was designated as ‘weight’ & ‘height’ model fields, my application refused inputting the float value, accepting only integer. I attempt to declare the FloatField at the forms, but it doesn’t seem to work. I have no idea what’s cause and desire to know how to be able to input the float value with solving this problem. Following are my code and Django is version 2.0 # Model.py class Profile(models.Model): class Meta(object): db_table='profile' user=models.OneToOneField(settings.AUTH_USER_MODEL,on_delete=models.CASCADE, primary_key=True) weight=models.FloatField(_('weight'),blank=False) height=models.FloatField(_('height'),blank=False) bmi=models.FloatField(_('BMI')) def __str__(self): return self.user.nickname # Form.py class BioRegisterForm(forms.ModelForm): class Meta: model=Profile fields=('weight','height') help_texts={'weight':('Kg単位で入力してください'),'height':('cm単位で入力して下さい')} def __init__(self,*args,**kwargs): super().__init__(*args,**kwargs) self.fields['weight'].widget.attrs={'placeholder':'Weight','required':True} self.fields['height'].widget.attrs={'placeholder':'Height','required':True} def clean_hight(self): value=self.cleaned_data.get('height') if value<50: raise forms.ValidationError('Type in with 「cm」') return value # View.py class BioRegisterView(CreateView): model=Profile template_name='mysite/bioregister.html' form_class=BioRegisterForm success_url=reverse_lazy('mysite/profile.html') and following are the bioregister.html, page in question <form method='post' action=""> {% for field in form %} <div> <div class='entry'> {{field}} </div> {%if field.errors %} <p> {{field.errors.0}}</p> {% endif %} </div> {% endfor %} {% csrf_token %} <input type="submit" value="Register" class='bottun2'> </form> Thank you -
Unable to pass django template variable array through post back to view

Django ability to add and remove foriegn keys through django admim
I want to be able to allow my user to add or remove foreign keys on one of my models. The business logic behind this is that there are many unique products that relate to one "product bundle".

Retrieving Unrelated Objects in Django REST Framework
My model consists of 3 classes: Offer, Application, and Contract. Relationships are as follows: Application to Offer: One to One Application to Contract: One to One Is there a way for me to access Contract from Offer via Application in a single REST call? I know how to access Application from Offer since they are related. A way around this is to relate Offer to Contract but I would prefer not to do this because it would not be considered good relational database design. Any help would be greatly appreciated. Thanks. -

How to post a react state as query parameters with Axios Async (django backend)
Works on postman but not react app. It did work a few months ago on react app. Goal: Want to post the state via axios async, to run a backend search (django). Situation: Currently the search output is all the available items in backend, which is a response reserved for a query with no content - so it is as though the state was sent empty even though the "value" did contain the correct state. Axios post request is as follows ("value" contains the state as an object and i have confirmed it does this successfully; "config" contains a token authorization check) const response = await Axios.post("URL",value, config); The response.data to this request is the whole list of items available, instead of just the ones matching the query params from the state carried by "value" FYI backend search done as below for each param, and then all categories joined in the end via .union() with the whole search output list is returned: ABC = params["ABC"] query = Q() for X in ABC: query = query | Q(X__contains=X) list = List.objects.filter(query) etc list = list_ABC.union(list_DEF, list_GHI, listings_JKL) return list Thanks for any tips on this! -
How to add a default value to fields in the Django Users model?
Currently, I have added a registration functionality to my website thanks to the Users model from the django.contrib.auth.models and I want to add a score field which will give by default 100 points once the user has registered. I have the following code for the user registration: forms.py from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm class UserRegisterForm(UserCreationForm): first_name = forms.CharField(max_length=25) last_name = forms.CharField(max_length=25) email = forms.EmailField() score = forms.CharField(max_length=5) # max value 99,999 class Meta: model = User fields = ['first_name', 'last_name', 'username', 'email', 'password1', 'password2'] views.py from .forms import UserRegisterForm from django.shortcuts import render, redirect def register(request): if request.method == 'POST': form = UserRegisterForm(request.POST) if form.is_valid(): return redirect('login') else: form = UserRegisterForm() return render(request, 'accounts/register.html', {'form': form} The current problem with my code is that the form displays the points field which shouldn't be the case and I am not sure how to indicate to Django that every time the user gets registered then the user should receive a 100 value in score. When I have used a postgresql db, I have implemented this as a default value,i.e., score = models.IntegerField(default=100) but this behavior doesn't work for the Users model from the from django.contrib.auth.models import User because you … -

Django Template Auto Sanitization vs Bleach Filter
I'm displaying data that is sometimes sanitized before saving to the database, and sometimes its not. Right now, we never render it directly to the template, because Django templates auto sanitize the data, but the problem is that they sanitize the data that has already been sanitized whereas using the bleach filter does not do that. So, for example, say my text is D&W and D&amp;W. I want both to render as D&W. if I insert it into the template as {% for d in data %} {{ d }} {% endfor %} The template outputs D&amp;W D&amp;amp;W and the browser shows D&W D&amp;W But when I use the bleach filter, like: {% load bleach_tags %} {% for d in data %} {{ d|bleach }} {% endfor %} In the template output, I get D&amp;W D&amp;W And in the browser I get D&W D&W Like I want. I have found very little comparing these two filters, but it seems like they do very close to the same thing. My question is: is there any reason not to use the bleach filter here? I'd love to see somebody expand on the differences between the two. PS: You can read about the …
