Align dropdown items to the left
I have placed checkboxes within a dropdown using bootstrap, however they are all center aligned. I would like to left align the dropdown items. Here's the code <div class="dropdown"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton2" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> Dropdown button </button> <form class="dropdown-menu" aria-labelledby="dropdownMenuButton2"> <label class="dropdown-item-left"><input type="checkbox" id="f1" name="result[]">AAAAA</label> <label class="dropdown-item"><input type="checkbox" id="f2" name="result[]">BBBBBBBBBB</label> <label class="dropdown-item"><input type="checkbox" id="f3" name="result[]">CCCCCCCCCCCCCCCCCCCC</label> <label class="dropdown-item"><input type="checkbox" id="f4" name="result[]">DDDDDDDDD</label> <label class="dropdown-item"><input type="checkbox" id="f5" name="result[]">EEEEEEEE</label> </form> </div> This is how it looks: I tried using text-align: left, align-self, etc using a separate css file, but it did not work. Please help me out. Thanks in Advance. -

Why cant' I upload and save images in Django running on Ubuntu server?
So I have a Django application running on Ubuntu and nginx. I have done everything that's required to upload image, and have a template with input fields for uploading images. There's actually no error in the process, but when I save it, I don't see any file attached in the Django admin. Let me show you my code and then explain further : mdoels.py class ArticleInput(models.Model): objects = models.Manager() ... img = models.ImageField(null=True, blank=True, upload_to="article_img") forms.py class ArticleInputForm(forms.ModelForm): ... img = forms.ImageField(required=False) class Meta: model=ArticleInput fields=['title', 'img', 'subtitle', 'contents'] views.py def articleinput(request): form = DansangInputForm(initial={'authuser':request.user}) if request.method == 'POST': form = ArticleInputForm(request.POST, request.FILES) if form.is_valid(): instance = form.save(commit=False) instance.authuser = request.user instance.img= request.FILES.get('img') ... instance.save() return redirect('/article/articlemain') return render(request,'article/articleinput.html', {'form':form}) articleinput.html <form method="post" class="form-group"> {% csrf_token %} ... <div class="row"> <div class="col col-12"> <div class="input-img">{{form.img|as_crispy_field}}</div> </div> </div> ... <div class="row"> <div class="col"> <button type='submit' class="btn all-buttons"> Save </button> </div> </div> My settings.py has no problem, believe me, and I've also done the chmod -R 777 command for granting permission to all of my users. So as mentioned, everything works fine in the whole process. I get no error messages, but when I attach an image file and hit "save" and … -
Python Django Simple Form Generation Question
I'm new to python and just starting in django, so go easy on me. I have a form.py file with a class like such. What's the best way to map a list of string items to the choices? Since tuples are immutable I am unsure of how to add my own data, which exists as a separate list, with each item being a string. I can't just type it out either, since the data is subject to change and it would be very troublesome. If there is a way to do this without tuples, but rather a list of singular strings, or an easy way to create a tuple out of the list it would help me so much. The documentation is hard to understand being a beginner to python and django, but it seemed like I was stuck using tuples from when I was reading it. class RecipeForm(forms.Form): THE_CHOICES =( ("1", "1"), ("2", "2"), ("3", "3"), ("4", "4"), ) THE_CHOICES2 = THE_CHOICES recipe_form = forms.ChoiceField(choices = THE_CHOICES) -

Better way to make dictionary of counts from a QuerySet based on a field in Django?
I have a queryset of objects that could have any text value in their field and I would like a dictionary of the counts of the values in that field. For example: I have a Test Drives Object which has a foreign key to vehicle, which has a make (Char field). I would like to know how many Test Drives each make had. I have actually solved it already, but I wonder if there is a better way using Django's inbuilt functionality. My existing, working solution: customer_test_drives_makes = customer_test_drives.values_list('vehicle__make', flat=True).order_by('vehicle__make').distinct() customer_test_drives_makes_dictionary = {} for make in customer_test_drives_makes : customer_test_drives_makes_dictionary[make] = customer_test_drives.filter(vehicle__make=make).count() print(customer_test_drives_makes_dictionary) This prints:{'BMW': 1, 'Honda': 1, 'Hyundai': 1, 'Mazda': 2} Which is correct -

stores user personalized news using django
I would like to ask a question on Django. Firstly I will explain what I want to achieve. My platform is a blogger can post news and users can follow only bloggers and can see news that posted by the blogger. I have blogger model, user model, follower model which keep track of relationships between blogger and users. I want to keep track of all news that related to a user can be stored in a queue in that way I can keep track of read and delete news that related to a user. Platform is similar to Whatsapp but all the data should be kept in backend database. Not in user phone storage What I suggest is Kee track of read news, delete news and all news that are related to a blogger and a user in follower table and when a blogger post a news, using Django signals to add that news to above mentioned field in follower table. Is it good solution? Or can you suggest a good one? -

querySelector, getElementById on div Inner HTML not working
Let say I have an ejs file with a nav bar containing a-tags of classes. Anytime each a-tags is click I do an http request to a server which response with a html code which I then set to be an innerHTMl of a div. The problem I am facing is that I can't do no queryselectors, get the elements or even do an event listeners on the html elements of the response HTML code. Is there a way to get this to work, because I really needed those to work. The External javascript file that I used is below: var arr = this.id.split('-') var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { // Typical action to be performed when the document is ready: document.querySelector('#nav-' + arr[1] + "-" + arr[2]).innerHTML = xhttp.responseText; } }; xhttp.open("GET", "/basic" + arr[1] + "-" + arr[2], true); xhttp.send(); })
