refresh component state every time it is rendered react
I have an API running and I am trying to fetch that to get some information about some products. I am using react router to route the products and using that to fetch the API. However, when I try clicking on a different product the information from the previous product remains no matter what I do. Here is my fetch: componentWillMount(){ let id = this.props.params.id + 3; let url = 'http://localhost:8000/api/item/' + id + '/'; return fetch(url) .then(results => results.json()) .then(results => this.setState({'items': results})) .catch(() => console.log(this.state.items)); and where I call the fill the information render() { return ( <div className="itemPageWrapper"> <div className="itemImgWrapper" /> <div className="itemInfoWrapper"> <Link className="backLink" to="/"> <span className="small"> <svg fill="#000000" height="13" viewBox="0 0 18 15" width="13" xmlns="http://www.w3.org/2000/svg"> <path d="M7 10l5 5 5-5z"/> <path d="M0 0h24v24H0z" fill="none"/> </svg> </span>All Items </Link> <h3 className="itemName">{this.state.items[Number(this.state.id)].name}</h3> <p className="itemCost frm">{this.state.items[Number(this.state.id)].price}</p> <p className="description"> {this.state.items[Number(this.state.id)].description} </p> <p className="seller frm">By <span>{this.state.items[Number(this.state.id)].brand}</span></p> <button className="reqTradeBtn normalBtn">Order</button> </div> </div> I receive an error saying TypeError: Cannot read property 'name' of undefined if I change anything. I am using a +2 because my API starts at 3. How would I make this work for all products -

Celery use Django Result Backend on Remote tasks
I have a Django application that use Celery to create async tasks. Some of these tasks live within the Django project and other live on a remote worker with its own code base. I currently use the django-celery-results package to store the results of task calls within the Django database so that I can easily query the status of calls using the Django ORM. This works fine when I call my "local" tasks, but it does not seem to work as well when I call remote tasks. For example: app.send_task("django.foo") # Return status SUCCESS and store result in DB app.send_task("remote.bar") # Stuck in PENDING and never create result in DB By reading the Celery Docs I found out that tasks can be stuck in PENDING if the client and worker doesn't use the same CELERY_RESULT_BACKEND setting. In this case I can't use the django-db backend on my remote worker, since it's not a Django application. So in this case... How do I store my results when doing remote calls in this manner? Note that in the case of remote.bar, I confirm that the remote worker receives the message and executes the method. Its just that my client (Django App) doesn't … -

Is there any way to run channels on azure app service?
I have currently run websocket locally with django channel (tutorial chat) I would like to submit the project on azure app service, I have enabled websockets in the control panel. however this does not work, once in my browser on the site I cannot connect to the socket either in http or https.

How do I write a Django ORM query with a relation that isn't defined in the model?
I'm using Django and Python 3.7. I have the following two models in my models.py file ... class Article(models.Model): created_on = models.DateTimeField(default=datetime.now) ... class ArticleStat(models.Model): article = models.ForeignKey(Article, on_delete=models.CASCADE, ) elapsed_time_in_seconds = models.IntegerField(default=0, null=False) I would like to write a Django ORM query where I select articles have a stat that's at least 5 minutes (300 seconds) old. However, I don't know how to reference the ArticleStat object from the Article object. Unsurprisingly, this Article.objects.filter(articlestat.elapsed_time_in_seconds.lte==300) produces a NameError: name 'articlestat' is not defined error. -
How to get the result from async function in python using Celery + Redis

How to loop through extended user model fields in Django template?
I have extended Django's user model with a Profile model: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile') date_of_birth = models.DateField() address = models.CharField(max_length=300) postcode = models.CharField(max_length=15) Then, I pass this data into a template via this view: def profile(request): args = {'user': request.user} return render(request, 'users/profile.html', args) Then I can access each field of the Profile model individually in the template with: <p>Your DOB is: {{ user.profile.date_of_birth }}</p> However, I want to use a for loop to say: {%for field in Profile model %} <p>{{field name}} = {{field value}} {% endfor %} But I've tried a lot of different things, none of them work, e.g. {% for field in user.profile.all %} <p>{{ field }}</p> {% endfor %} (This compiles but is blank when the template is ran) -

How to update nested serializers with file field
I have 2 models: Profile and Image. Profile field "logo" related to Image with models.ForeignKey() construction. I want to update my Profile record with update request (Patch with JSON payload). How can I do that? I've tried to send this JSON { "name": "TestName", "company": "myCompany", "phone": "33222111", "website": "site.com" } And it's OK, record have updated. But!

How to test clean_<fieldname> method?
I try to write a test for my clean_ method. Here is the code for my test def test_clean_restraints(self): form = NewTaskForm(dict(restraints="90 20 <>")) form.clean_restraints() At this step I receive an error: Error Traceback (most recent call last): File "/home/user/django_projects/my_webservice/tasks/tests/test_forms.py", line 12, in test_clean_restraints form.clean_restraints() File "/home/user/django_projects/my_webservice/tasks/forms.py", line 22, in clean_restraints if self.cleaned_data.get('restraints') == '': AttributeError: 'NewTaskForm' object has no attribute 'cleaned_data' NewTaskForm looks like this: class NewTaskForm(ModelForm): class Meta: model = Task restraints = forms.CharField() region = forms.CharField() interactions = forms.CharField() def clean_restraints(self): if self.cleaned_data.get('restraints') == '': return self.cleaned_data.get('restraints') data = self.cleaned_data.get('restraints').strip().split('\n') regexp = re.compile(r'^(\d+)[\t ]+(\d+)[ \t]+([><]{2})?$') cleaned_data = [] for i, line in enumerate(data): match = regexp.match(line) if not match: raise forms.ValidationError(f"Error in restraints in line {i + 1}") else: rst_1, rst_2, loop_type = match.groups() rst_1 = int(rst_1) rst_2 = int(rst_2) cleaned_data.append((rst_1, rst_2, loop_type)) return cleaned_data I'm using Django 2.1, python 3.7.1, PyCharm 2018.3.3 Professional I tried to run it under debugger in PyCharm but things goes crazy. I receive different error message. It looks like debugger stopped after full form validation ignoring breakpoints. I have no idea what is going on.
