display data in multiple columns with for loop
I'm sure this is a simple answer but for the life of me I cant figure / find out how to go about this. I want to display blog posts from my data base in three equal columns. When I start looking into the bootstrap docs this is the code given. <div class="container"> <div class="row"> <div class="col-sm"> One of three columns </div> <div class="col-sm"> One of three columns </div> <div class="col-sm"> One of three columns </div> </div> </div> However If I go to implement it I dont understand how i would be able to put the for loop on it without it repeating everything 3 times. IE: {% for post in posts.all %} <div class="row"> <div class="col-sm"> <img class="post-image" src="{{ post.image.url }}" /> </div> <div class="col-sm"> <img class="post-image" src="{{ post.image.url }}" /> </div> <div class="col-sm"> <img class="post-image" src="{{ post.image.url }}" /> </div> </div> {% endfor %} If you could please point me in the right direction on how to go about this it would be very much appreciated bootstrap is not a requirement. -

Django google books API totalItems is changing
I am creating an application that retrieves data from the google books API. At the very beginning I download a number of books from JSON ["totalItems"] and iterate through the for loop, calling the API in order to get another 40 items. The problem is that the number of books increases and decreases during iteration, so when, for example, on a 550 book, I get a list index out of range error. Anyone please help me download all the books? My request looks like this: requests.get(f'https://www.googleapis.com/books/v1/volumes?q={search}\ &maxResults=40&startIndex={end_range}') end_range is increased by 40 each time data is downloaded. -
Go import from specific branch github in the same repository where it is hosted
I have a repository with a golang project in github, I need to import in a module a specific branch, to make relevant modifications. It looks like this: package events_entity import ( "github.com/repository/utils/date_utils" "github.com/repository/utils/utils/error_utils" "github.com/repository/utils/utils/hour_utils" "strconv" "strings" ) The importation is always done directly from the master. I just need this module to import from a different branch. Thanks!!! -

Custom User Primary Key - Django
I have a Django website and a format similar to google sheets in which people can add data and it shows up in a row. To the left is the number associated with that row of data. Normally I used pk which worked great because when one data row was deleted no other ones changed. Now I have 2 users and I'm separating the data based on ForeignKey fields in all of my models. The problem with this is, for example, User1 adds 1 row of data then User2 adds one row of data then User1 adds another row of data, then when User1's data is being displayed it will show 2 rows labeled 1 and 3. I need them to be specific to the user and in numerical order. It is as if I need a separate pk for each user in the same model. I temporarily fixed this by {{ forloop.revcounter }} in the forloops of the rows. This now keeps the row number in numerical order and specific to the user. The problem is that if User1 now deletes the first data row labeled #1 then now the table only shows 1 row and the data row … -
Ordering by multiple fields
I'm wanting to order a queryset based on a couple of different related fields Models.py class Appointment(models.Model): start_time = models.DateTimeField(auto_now=False, auto_now_add=False, null=True, blank=True) class Event(models.Model): start_time = models.DateTimeField(auto_now=False, auto_now_add=False, null=True, blank=True) class Job(models.Model): event = models.ForeignKey(Event, on_delete=models.SET_NULL) appointment = models.ForeignKey(appointment, on_delete=models.SET_NULL) views.py qs = Job.objects.all().order_by('event__start_time','appointment__start_time') Is this the correct way to do this? Will this always order all of the jobs in the correct order based on the associated star time? Thanks! -
The view basket.views.basket_remove didn't return an HttpResponse object. It returned None instead
Can someone explain me why am i getting this error? I am creating online store in which basket functionality depends on sessionid in cookies. Look, I have a function basked_add on every product in store, which adds specified product to basket and it works correctly without any issues. I have also a function basket_delete in basket to remove specified product from basket, and somehow it doesn't work correctly. And this is the main reason why i made this question. Function basket_delete is called by JQuery like that (equal to basked_add): 1. basket.html $(document).on('click', '#remove-button', function (e) { e.preventDefault(); $.ajax({ type: 'POST', url: '{% url "basket:basket_delete" %}', data: { productid: $('#add-button').val(), csrfmiddlewaretoken: "{{csrf_token}}", action: 'post', }, success: function (json) { }, error: function (xhr, errmsg, err) {} }); }) 2. basket > urls.py app_name = 'basket' urlpatterns = [ path('', views.basket, name='basket'), path('add/', views.basket_add, name='basket_add'), path('delete/', views.basket_delete, name='basket_delete'), ] 3. Then function is getting executed basket > views.py from django.http.response import JsonResponse from basket.basket import Basket def basket_delete(request): basket = Basket(request) if request.POST.get('action') == 'post': product_id = int(request.POST.get('productid')) basket.delete(product=product_id) response = JsonResponse({'Success': True}) return response basket > context_processors.py from .basket import Basket def basket(request): return {'basket': Basket(request)} basket > basket.py class … -
