How to create dropdown menu from model in django
im currently trying to create a drop-down menu for my Post categories in my base.html so that it gets displayd on every of my templates. Later on i want that a user simply clicks on a category item and gets forwarded to the specific category. I'm a bit confused as to what I should include in my forms and how to call that form on my base.html. views.py: def category_dropdown(request): categories = Category.objects.title() return render (request, 'quickblog/base.html', {'categories': categories}) models.py ... # Categorys of Post Model class Category(models.Model): title = models.CharField(max_length=255, verbose_name="Title") description = models.TextField(max_length=10000, null=True) categorycover = fields.ImageField(upload_to='categorycovers/', blank=True, null=True, dependencies=[ FileDependency(processor=ImageProcessor( format='JPEG', scale={'max_width': 600, 'max_height': 600})) ]) class Meta: verbose_name = "Category" verbose_name_plural = "Categories" ordering = ['title'] def __str__(self): return self.title #Post Model class Post(models.Model): author = models.ForeignKey('auth.User', on_delete=models.CASCADE) title = models.CharField(max_length=200) text = models.TextField(max_length=10000) category = models.ForeignKey(Category, verbose_name="Category", on_delete=models.CASCADE, null=True) ... forms.py class PostForm(forms.ModelForm): class Meta: model = Post fields = ['title', 'text', 'tag', 'postcover', 'postattachment', 'category'] captcha = CaptchaField() Thanks :) -
how can I use 'POST' method with django_filter
I have a form using django_filter that works ok. When I click 'NEXT' button I need : 1) save the informations that are selected in the grid 2) go to the next form In my views.py i use instancia_item_filter = itemtiposervicoFilter(request.GET, queryset=instancia_item_list) Like that it´s possibile to show the informations on the grid and sum selected lines. If i change it to post method i cannot do that. See the screen bellow. views.py def servico_create(request, id=None): instance = get_object_or_404(usuario, id=id) form = itemtiposervicoForm(request.POST or None) # Seleciona a lista para ser exibida no grid instancia_item_list = itemtiposervico.objects.all().order_by('desc_itemtiposervico') instancia_item_filter = itemtiposervicoFilter(request.GET, queryset=instancia_item_list) paginator = Paginator(instancia_item_filter.qs, 100) page = request.GET.get('page') try: response = paginator.page(page) except PageNotAnInteger: # if page is not an integer, deliver first page response = paginator.page(1) except EmptyPage: # if page is out of range, deliver last pages of results response = paginator.page(paginator.num_pages) if request.method=='POST': print('save and go to the next form') context = { "filter": instancia_item_filter, "response": response, "form": form, } return render(request, 'servico/teste.html', context) my teste.html template has something like that: <form class=" bd-form-28 " action="" name="form-name" method="GET" enctype="multipart/form-data"> {% csrf_token %} <div class=" bd-select-5 form-group"> <label class="bd-form-label">Serviço</label> {{filter.form.tiposervico}} </div> </form> <table id="table" width="100%" border="0" cellspacing="0" cellpadding="0"> … -

Uninstall Packages that aren't used by pip
Since the day I started building my website, I installed many packages sometimes to test bunch of codes, sometimes for the project itself (Later I figured out it's not the package needed). But now, when I run pip freeze I have a list of packages, It becomes hard to me to uninstall packages that aren't used. I am about to deploy my website. I'm using the latest version of pip, and running a Django Project I have virtual environment with virtualenv python 3.5 OS: Linux (Ubuntu) Many thanks you awesome people! -

Django dynamic FileField upload_to
I'm trying to make dynamic upload path to FileField model. So when user uploads a file, Django stores it to my computer /media/(username)/(path_to_a_file)/(filename). E.g. /media/Michael/Homeworks/Math/Week_1/questions.pdf or /media/Ernie/Fishing/Atlantic_ocean/Good_fishing_spots.txt VIEWS @login_required def add_file(request, **kwargs): if request.method == 'POST': form = AddFile(request.POST, request.FILES) if form.is_valid(): post = form.save(commit=False) post.author = request.user post.parent = Directory.objects.get(directory_path=str(kwargs['directory_path'])) post.file_path = str(kwargs['directory_path']) post.file_content = request.FILES['file_content'] <-- need to pass dynamic file_path here post.save() return redirect('/home/' + str(post.author)) MODELS class File(models.Model): parent = models.ForeignKey(Directory, on_delete=models.CASCADE) author = models.ForeignKey(User, on_delete=models.CASCADE) file_name = models.CharField(max_length=100) file_path = models.CharField(max_length=900) file_content = models.FileField(upload_to='e.g. /username/PATH/PATH/..../') FORMS class AddFile(forms.ModelForm): class Meta: model = File fields = ['file_name', 'file_content'] What I have found was this, but after trial and error I have not found the way to do it.

Installed Python and Django Using Chocolatey - How Do I Run Django?
Apologies if the answer seems obvious. I've installed Python3, Django, Git and an environment for said Python without a hitch. Now I'm unsure how I get Django up and running. I implemented a "C:>/workspace/local_sites" folder for my Django projects to be in, as seen below: local sites folder But I'm unsure as to where I go from here. Every tutorial I come across appears to be running Django through methods I cannot access since I used PowerShell to install the program rather than CmdPrompt. I just want to create a working, interactive website, that I can store in a folder and come back to whenever I please. Again, apologies if the answer seems obvious. Thank you for your time. -
Looping over for loop inside another for loop in Django
First see my code please : My model : class review_product_individual(models.Model): product_id = models.CharField(max_length=30) product_star = models.CharField(max_length=30) product_review_message = models.CharField(max_length=255,blank=True) product_reviewed_by = models.CharField(max_length=30) product_review_date = models.DateTimeField(auto_now_add=True, blank=True) In views : product_review = review_product_individual.objects.filter(product_id = productID).order_by('-product_review_date') Here product_star will contain 1 to 5 rating and stored as char. Now what I want to do is this I will access each product_review object in Django template in for loop and inside the for loop I will iterate product_review.product_star times.please see the template code here :` {% for product_review in product_review %} <li> <div class="review-heading"> <h5 class="name">{{product_review.product_reviewed_by}}</h5> <p class="date">27 DEC 2018, 8:0 PM</p> <div class="review-rating"> {% for i in {{product_review.product_star}} %} <i class="fa fa-star"></i> {% endfor %} <i class="fa fa-star-o empty"></i> </div> </div> <div class="review-body"> <p>{{product_review.product_review_message}}</p> </div> </li> {% endfor %} But only one star is printing as the value of {{product_review.product_star}} =3 I want 3 stars. I could not do in views because product_review contains many objects. So how can I do it ? -

URL Patterns and Views
I have an application which requests data based on certain parameters. I use two functions to handle the requests and then create two objects from the responses. I am able to iterate through each object individually and display the data of a particular object on my webpage, but when I try to use both functions simultaneously, only one function iterates through the object. It is my understanding that this issue has something to do with URL patterns, but I am not as to what the best approach would be. Below you will find my urlpatterns, my functions, and the html I use to access the view. urlpatterns = [ path('', views.customer, name='customer'), path('', views.information, name='information'), ] def customer(request): for i, contact in enumerate(contactObj): try: contacts = contactObj context = {'contacts': contacts} except KeyError: print() return render(request, 'uccx/home.html', context) def information(request): for i, ticket in enumerate(ticketObj): try: tickets = ticketObj context = {'tickets': tickets} except KeyError: print() return render(request, 'uccx/home.html', context) <tbody> {% for ticket in tickets %} <tr class="{% cycle 'row1' 'row2'"> <td> {{ ticket.id }} </td> <td> {{ ticket.company.name }} </td> <td> {{ ticket.summary }} </td> </tr> {% endfor %} -

Django form - can I return any variables when raising a ValidationError
I have built a custom form, with several custom fields (containing the primary keys of my models) so I am not using clean_() methods, just clean(). I obtain data out, and if a field doesn't contain certain inputs, I raise a ValidationError. However, I would not like this to fully reset my form inputs... Is there a way to 'save' the state of the form when submitting... or return values even when you are raising a validation error? form: def clean(self): data = self.data my_data = data.getlist('my_data') ... use my_data to create pandas dataframe ... missing = df.loc[( ((df['status'] == 'report') | (df['status'] == 'toconfirm')) & (df['evidence'] == ''))] if not missing_evidence.empty: error_ids = missing_evidence['obj'].tolist() error_variants = [str(o) for o in error_ids] error_variants = "; ".join(error_variants) raise(forms.ValidationError(('%(value)s incorrect'), params={'value': error_variants}, )) ** here can I return dataframe, and re-set up my form? ** -
possible django race condition
@receiver(post_save, sender=MyRequestLog) def steptwo_launcher(sender, instance, **kwargs): GeneralLogging(calledBy='MyRequestLog', logmsg='enter steptwo_launcher').save() # remember to remove this line if instance.stepCode == 100: GeneralLogging(calledBy='MyRequestLog', logmsg='step code 100 found. launch next step').save() nextStep.delay(instance.requestId,False) I think I just witness my code losing a race condition. The backend of my application updates the status of task one, and it writes a stepCode of 100 to the log when the next task should be started. The front end of the application polls to report the current step back to the end user. It appears that after the backend created an entry with stepCode 100, the front request came in so soon after, that the if instance.stepCode == 100: was never found to be True. The GeneralLogging only reports one entry at the time of the suspected collision and does not launch the nextstep. My question is to 1) Confirm this is possible, which I already suspect. and 2) A way to fix this so nextStep is not skipped due to the race condition. -
uwsgi listen queue fills on reload
I'm running a Django app on uwsgi with an average of 110 concurrent users and 5 requests per second during peak hours. I'm finding that when I deploy with uwsgi reload during these peak hours I am starting to run into an issue where workers keep getting slowly killed and restarted, and then the uwsgi logs begin to throw an error: Gracefully killing worker 1 (pid: 25145)...

django file uploaded for processing- how to correctly specify output-download file-type?
I have a simple django platform where I can upload text files. Ultimately I want to return a downloadable mp3 audio file made from the text in the uploaded file. My problem currently is that I cannot seem to correctly specify the type of file that the website outputs for download. As practice I originally tried to have the downloadable output of the website as the content of the uploaded file written to a new file called 'result.txt': views.py (code adapted from https://github.com/sibtc/simple-file-upload) def simple_upload(request): if request.method == 'POST' and request.FILES['myfile']: myfile = request.FILES['myfile'] print(str(request.FILES['myfile'])) x=str(myfile.read()) #print(x) new_file=open("/path/simple-file-upload/media/result.txt", "w") new_file.write(x) new_file.close() with open('/path/simple-file-upload/media/result.txt', 'r') as pdf: response = HttpResponse(pdf.read()) response['content_type'] = 'text' response['Content-Disposition'] = 'attachment;filename=result.txt' return response return render(request, 'core/simple_upload.html') While writing the content of the uploaded file to a 'result.txt'- returning the file in a downloadable text file is problematic..... Rather than being returned as a txt file it is returned as an HTML file- 'result.txt.html'. Inspecting the content of this HTML file shows the original text content of the uploaded file but in an HTML format and the text is encased in b''.

Django: need Dynamic login using info from database redirect after login, using built-in login
After I login, I need to redirect to another page while adding URL parameters to the URL of the next page. I get the value of these parameters after the user is authenticated because they need to be accessed from the user database table. I heard about using the next parameter but I don't know how I would use it since I need to access the database table and I can't do that from urls.py. This is my url.py line for login right now: url(r'^$',auth_views.login, name='login',kwargs={ 'authentication_form':loginPlaceHolderForm, }), I'm not really sure what other info you need so just ask for it in the comments and I'll be sure to add it. -
