Error in Downloading Files from Django app in Production with Gunicorn & Nginx
I have deployed my Django app on AWS EC2 Instance using this guide. Everything is working fine but the error arises when I download an excel file. (Excel is created using opnenpyxl library). While downloading an xlsx file the application is returning download.htm file. Everything work great on a development server. I tried Adding and removing the download tag. <a href="{% url 'download_estimate_excel_file' project.id project.name %}" class="dropdown-item" download> Download Excel </a>. [Didn't Work] Adding [service] Environment="LANG=ru_RU.UTF-8" to gunicorn.service file (found this on StackOverflow also). [Didn't Work] Thanks in advance. -

Dynamic URL routing from html form within action in Django
I have a simple form which shall take a user input and directly send the user to a dynamic url using the input. Inputing "111" into the form shall send the user to /number_input=111 Somehow i can not get it done, since i do not know how to get direct variable value from the form to the view immediately. I can build it with 2 views but that looks somehow ugly and inconvenient. Here is what i have so far: The Form: (within index.html) <form action={% url 'my_view'%} method="POST"> {% csrf_token %} <p><input type="text" name="inp_number" placeholder="Insert Number"/></p> <p><input type="submit" value="Submit"/></p> </form> views.py: def number_view(request): if request.method == 'POST': context = {'number': request.POST['inp_number']} return render(request, 'number.html', context) urls.py from . import views urlpatterns = [ path('number_input=<int:number>/', views.number_view, name='number_view') ] The dynamic part here (int:number) will make the code fail, since iam not sending a value from the form, right? But i only know how to send static values (i.e. action={% url 'my_view' 111 %}. How can i send direct dynamic values from the form itself (the value that the user inputs in the submit button)? number.html <h2>This page is for number {{ number }}</h2> -
About customizng drop down menu information in django import export module

The second model is for adding new categories for the book, for example: recipes, toolbooks... etc. The model id will be generated automaticly by django too. The third model is for a mapping table, which connects the book data added by the first model, and the category data added by the second model together by using ids from above two models as foreign keys. After this, the data should be mapped together like this: John's Story(book name), Adventures(category). My question is, after I successfully built up those three models, and I added following data by using the django admin page. books id book_name book_desc 1 John's Story a story for kids. 2 Best recipes good foods. classes id class_name 1 Adventures 2 Toolbooks By using the … -

django custom forms with models, also with 'choices' as values, how should I approach this problem?
django forms is giving me a pretty bad headache... I've been struggling with this for 2 hours now. I wanted to make a custom form for a model to be able to add objects to it and also be able to move the fields as I want to (instead of using form.as_p (or form|crispy), I wanted to put the entire form in a grid-like table using a custom pattern, not only putting one under another) but whenever I put a choicefield (which is either a choicefield or a foreignkey) their values are empty and also, 3 out of 4 formfields are actually shown, one remains the default. It contains fields='__all__' with 3 choicefields and 1 floatfield each with a label, nothing more. To show the forms in html I used {% for field in form.visible_fields %} {{ field.label_tag }} {{ field.errors }} {{ field }} {{ field.help_text }} {% endfor %} which works well. Am I trying to solve the problem in a wrong way? I'll come back to this topic tomorrow, I'll need some rest now but I don't understand why passing a choices=TheModel # or # choices=TheModel.ojbects.all() breaks the entire thing. Is there a website or a youtube … -
How do I collect all my Django data from the database before invoking my serializer?
I'm using Python 3.9 and Django 3.2. I have a Django model with a couple of many-to-many relationsips class Coop(models.Model): objects = CoopManager() name = models.CharField(max_length=250, null=False) types = models.ManyToManyField(CoopType, blank=False) addresses = models.ManyToManyField(Address, through='CoopAddressTags') enabled = models.BooleanField(default=True, null=False) phone = models.ForeignKey(ContactMethod, on_delete=models.CASCADE, null=True, related_name='contact_phone') email = models.ForeignKey(ContactMethod, on_delete=models.CASCADE, null=True, related_name='contact_email') web_site = models.TextField() description = models.TextField(null=True) approved = models.BooleanField(default=False, null=True) proposed_changes = models.JSONField("Proposed Changes", null=True) reject_reason = models.TextField(null=True) I can search for my model using a manager class that builds a query like so ... def find( self, partial_name, types_arr=None, enabled=None, city=None, zip=None, street=None, state_abbrev=None ): """ Lookup coops by varying criteria. """ q = Q() if partial_name: q &= Q(name__icontains=partial_name) if enabled != None: q &= Q(enabled=enabled) if types_arr != None: filter = Q( *[('types__name', type) for type in types_arr], _connector=Q.OR ) q &= filter if street != None: q &= Q(addresses__raw__icontains=street) if city != None: q &= Q(addresses__locality__name__iexact=city) if zip != None: q &= Q(addresses__locality__postal_code=zip) if state_abbrev != None: q &= Q(addresses__locality__state__code=state_abbrev) q &= Q(addresses__locality__state__country__code="US") queryset = Coop.objects.filter(q) print(queryset.query) return queryset In my view, I invoke and return the data using coops = Coop.objects.find(...) serializer = CoopSearchSerializer(coops, many=True) in which the serializer looks like class CoopSearchSerializer(serializers.ModelSerializer): ... …
