How to create dynamic route for file paths in flask app
In my application I have a file browser. The file names are urls for a detail page, wich takes as argument the bucket and the object name. @app.route("/object_info/<string:bucket_name>/<string:object_name>/", methods=["POST", "GET"]) def object_info(bucket_name, object_name): Like this: http://localhost:5000/bucket_name/Grain_08.tif/ This is working fine, but I cannot display the files in subfolders like in 1aaaa, because if I click to the 2. row the url is: http://localhost:5000/bucket_name/1aaaa/Grain_11.tif and so the url pattern for the object_info route is not working. I have tried solutions like optional routes, but the depth of the subfolders are not limited. Thats mean there can be a file in 4 subfolders. So I need some dynamic stuff so I can display the objects in the deeper folders. -

Django/Python3: Convert complex inner join query to
I am developing a book sales application on Django and I need to get a list of the most popular book categories from the books sold. Models: Category (id, name) BookCategory (id, category[FK], book[FK]) Sales(id, book[FK]) Book(id, name) The following SQL is the equivalent of my requirement but I have no idea how to use this using Django models and filtering. sql = "SELECT c.* FROM category c INNER JOIN book_category bc ON c.id = bc.category_id INNER JOIN sales s ON s.book_id = bc.book_id GROUP BY c.id ORDER BY count(s.id) DESC" I have used the following lines of code to execute this but get an error. categories = Category.objects.raw(sql) Object of type 'RawQuerySet' is not JSON serializable How can I accomplish this? -

How do I get an AJAX callback function to render a Django url or html template with parameters?
I am a beginner and working on an app where I want to redirect the user to a checkout-basket (Django url via POST? Or render html template with variables?) after checking if anything is saved in localStorage. So I check that and use AJAX to send that data to my Django url in order to render that template passing on the variables in localStorage as JSON. But return render(request, "pizza/prebasket.html", context) in views.py doesn't work: even though the data is recieved, prebasket.html is not rendered. I read that that's because AJAX doesn't allow that and instead I need to post through AJAX's callback function. But how do I do that via POST and how do I pass on the parameters to my view or directly to my html template? (window.location.href only handles GET requests, so I guess that doesn't work). Here's my JavaScript and my views.py: function previous_selection () { if (localStorage.getItem("preselection") != null) { const data = new FormData(); data.append("preselection", preselection); const request = new XMLHttpRequest(); request.open('POST', '/prebasket'); const csrftoken = getCookie('csrftoken'); request.setRequestHeader("X-CSRFToken", csrftoken); console.log("DATA IS: ", data); request.send(data); console.log("PRESELECTION IS: ", preselection); request.onload = () => { // HOW DO I CALL MY URL WITH PARAMETERS HERE? }; … -

Django form containing different types of fields
I'm wanting to add a MultipleChoiceField with a CheckboxSelectMultiple widget to a model/form containing other types of input. I am wondering how I can do this and add classes to the entire MultipleChoiceField as well as classes to each of the choices (for bootstrap). I have tried adding a class to the whole MultipleChoiceField using: preferred_subjects.widget.attrs.update({'class': 'form-control'}) but it doesn't work. Even if it did, I also want to add classes to each of the options, but I am unsure how. I usually output forms using {{ form|crispy }} but since I want to add classes to each of my MultipleChoiceField options im guessing i'll need to use {% for option in fieldset %} and add classes as each is output. But the problem is I have other types of input in that same form which I don't want to add the class names to. Here is my code: class PersonalInformation(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) first_name = models.CharField(max_length=200, default='') dob = models.DateTimeField('Date of birth (mm/dd/yyyy)', null=True, default=now) subjects = model.CharField(max_length=200, default='') class PersonalInformationForm(forms.ModelForm): SUBS = ( ('MATH', 'Maths'), ('ENG', 'English'), ) subjects = forms.MultipleChoiceField(choices=SUBS, widget=forms.CheckboxSelectMultiple()) class Meta: model = PersonalInformation fields = ['first_name', 'gender', 'subjects'] Summary - I want to … -

Python crashes when including a template
this is the first time that i ask something here so excuse me if im been not so clear about the issue. At my views, i have the def home that renders the template home.html passing two variables: posts and trendList. Home.html: <div class="create"> {% include 'snippets/create.html' %} </div> <div class="main"> <div class="feed"> {% block detail %} {% endblock detail %} {% include 'snippets/post.html' %} </div> <div class="trends"> {% include 'snippets/trendList.html' %} </div> </div> The code only freezes when i do the 'include post.html'. If i call it in block format, it does not load the post.html inside the block. Post.html <div class="post"> <p> {{ post.text }}</p> <p> {{ post.created_at }}</p> <p> {{ post.author }}</p> <a href="{% url 'who_liked' pk=post.pk %}" >{{ post.likes.count }}</a><br> <a type="button" href="{{ post.pk }}" >Like</a> </div> {% endfor %} But if i click in an object of trendList, it works fine, redirecting me to the home.html with the template loading inside the blocks. I don't know why 'include post.html' crashes the program and putting it in blocks will do nothing. Thanks in advance. -
Django - Rendering a template multiple times in a loop
I have a Django view that receives a list of selected files in request. I want to iterate over all files and render the same template for each file (one after the other). Is there a way/hack to re-render the template with the modified context without returning from the view? Or is there a way to do it with javascript using local-storage, i.e., calling the view for each file (one after the other)? -
