How do I change input type of form field in django forms?
I have a form class in my form.py file where I initiated properties of form fields. I want to change my 'Description' field from an input field to a textarea field of height 5 lines. Also want to change my 'Deadline' field to a date input field because at the moment it's an input text field. class JobPost_form(ModelForm): class Meta: model = Job_post fields = "__all__" def __init__(self, *args, **kwargs): self.fields['Job_role'].widget.attrs.update( {'class': 'form-control Password2', 'id': 'form3Example1c', 'placeholder': 'Job role'}) self.fields['Company'].widget.attrs.update( {'class': 'form-control', 'id': 'form3Example1c', 'placeholder': 'Company'}) self.fields['Deadline'].widget.attrs.update( {'class': 'form-control', 'id': 'form3Example1c', 'placeholder': 'YYYY-MM-DD HH:MM:SS'}) self.fields['Description'].widget.attrs.update( {'class': 'form-control', 'id': 'form3Example1c', 'placeholder': 'Description'}) -
Selenium thread only works once
I have a dockerized Django app with some threads. Those threads perform periodic tasks, and use Selenium and Beautiful Soup to scrap data and save it to the database. When initializing one thread, the first scrap goes well, data is checked and the function sleeps. However, when the sleep finishes the next scrap isn't performed. This is the thread head code: def thread1(): time_mark = 0 while True: print('Thread1 START') op = funct_scrap(thread1_url) ... sleep(60) The funct_scrap scrapes the web using Selenium, works for the first time but it stops after that. I'd need it to check periodically. In development server works well, but now on Docker there is this problem. What's going on? -

Combining multiple Django filters
So I'm struggling with filtering my products in Django. I currently have a search bar which works and the result of submutting a query ('whey' in this case) looks like this: The thing I can't figure out is how to get the sort filter to work now ('Sorteer op:). Because when selecting an option my function in the view gets called, which looks like this: def zoekopdracht(request): if request.GET.get('search') != '': try: search = request.GET.get('search').lower() queryset = models.Product.objects.annotate(search_name=Concat('title', Value(' '), 'categorie', 'brand' , output_field=TextField())) products = queryset.filter(search_name__icontains=search) product_amount = len(products) # sorteer filter filtered = SortFilter( request.GET, queryset=products ) # paginator paginator = Paginator(filtered.qs, 12) page = request.GET.get('page') try: response = paginator.page(page) except PageNotAnInteger: response = paginator.page(1) except EmptyPage: response = paginator.page(paginator.num_pages) product_front_end = { 'final_products': response, 'filter': filtered, 'count': product_amount, } except AttributeError: print(request.GET) response = [] product_front_end = { 'final_products': response, } else: response = [] product_front_end = { 'final_products': response, } return render(request, 'zoekopdracht.html', product_front_end) Because the GET request from the search bar is empty now I lose the products. Is there a way to get the current products back to the view function? That way I can use my SortFilter on the current products. urls.py: urlpatterns … -

When and where is `Model.blank` checked by DRF?
I have a model class SomeModel(models.Model): emails = ArrayField(models.EmailField(), default=list) And let's say I have the following Serializer of the model: class SomeModelSerializer(serializers.ModelSerializer): class Meta: model = SomeModel fields = ['emails'] The email field is not blank-able, i.e: It's required to set a value for it when submitting a Form of the model, or when saving its Serializer. Everything works as expected. So my understanding is that DRF relies on Django's internal machinery to validate whether emails is missing on the Serializer data or not. But the thing is that I can't find where (and when) this happens. I've found that DRF is not calling the Model's clean() method anymore (link)... So do you have any idea of when and where DRF checks for a field's blank value? Thanks! -
DRF with JS Framework retrieving state from URL and making request gets page not found
I'm new in Django. I worked with PERN and PEAN stack before. So, let's say I have product page which stores page state in a URL, and retrieves it when reloading, then makes request to backend, to "product/getOne". But, this works only for first time when actually gets it from link state. Then, when I reload I'm getting Page Not Found Error, and my URL looks like this. Why current path is matter if my request defined like "product/getOne" in my client? -
