How I can do a “Select Dropdown” with values from database, using only html and JS? I do something that works ok, but if a put the .html in another app, doesn’t work.

How I can do a “Select Dropdown” with values from database, using only html and JS? I do something that works ok, but if a put the .html in another app, doesn’t work.

Make query set, return value, catch it it the html

Like this? For me, works only in one app, but I want to put this .html in another app, but doesn't work <select name="paciente" id="paciente" required> <option value="" selected>Select on option</option> {% for paciente in object_list %} <option value="{{ paciente.id }}">{{ paciente.nome_paciente }}</option> {% endfor %} </select>

If this code works in the one application, but does not work in another app. Firstly you should debug it, print the result from database, check browser console, if you would like get help, you should provide more information, errors description.

Don’t have any errors. Only not work. The page debug, but the drop-down don’t have any element.

hello guys, can anyone explain me why does the following code raises an error in the first loop and does do that in third loop? convos = Convo.objects.filter(user=request.user).order_by("-activated_on") activated_convo = convos[0] # required to evaluate first element of queryset activated_convo.is_activated = True for c in convos: print(c.is_activated) # get an error break for c in convos: c.is_activated = True break for c in convos: print(c.is_activated) # doesn't return an error break because in both cases I'm evaluating the first element of quesryset and set the is_activated attribute to True

you're applying is_activated only to the first convo, so in the first loop you get an error when iterating over the 2nd convo in the third loop you won't get any error because in the 2nd loop you set is_activated = True to each convo

what the error reports?

that kind of bothers me because on stackoverflow the same question wasn't answered https://stackoverflow.com/questions/54396296/why-doesnt-saving-queryset-element-at-index-work-in-django

id(c) changes every time, but that's because the fresh memory is allocated in the heap after every program (view handler) execution

if you try something like: a = {"a": 1} print(id(a)) the value will be also different from execution to execution

so the queryset iterator is creating a new object, hence there's not is_activated set to the object

Hello friends I had a model, now I added some records and commands python manage.py makemigrations python manage.py migrate I enter it in the terminal of my project, but my records are not added to my table. I even deleted the migrations folder with its junk files and rebuilt it from the beginning, but again, they are not added to my database, and it is the same as the previous table.

YouTube using django right? Is that only for just user authentication or other things? Is there anyway to clear this kinda doubts

Hello guys, i have a question. How i can filter products in already filtered page? For example, when ur searching anything in ebay, let's say ipad, ur getting list of these product, and u can also filter them by price or anything.

you can use Q

This is don't work for me because, at the beginning I need to filter the products by their names, and after receiving the page, filter by price, if I use Q, then I will need to prescribe all the filters at once

can you use two serializer? you'll filter products by name in the first serializer. then you'll filter by prices in the second serializer.

im sorry but im not using drf or django api yet, is it possible to create this functionality by using normal django?

example: def products_page(request, query): products = Product.objects.filter(name__icontains=query) kwargs = request.GET price_up = kwargs.get('price_up') price_down = kwargs.get('price_down') if price_up: products = products.filter(price__gte=price_up) if price_down: products.filter(price__lte=price_down) return render(request, 'products.html', {'products': products}) Do you understand what i am saying?

I understand, but when I performed a search, and then I try to filter by price, the first filter that filtered by names is erased from the address bar and replaced with a filter that filters by prices, resulting in the error "ValueError at /search/ Cannot use None as a query value"

emm. i don't have another options, sorry bro

can you please tell me how to implement it?

Are you using get or post?

yes im using get method

It would be more simple using post, as you can send as many data you want
