Best way store data when callback -Python - Django - Bokeh - Webdevelopment
When doing a bokeh callback (zooming), new 500 values have to be loaded. xRangeStart and xRangeEnd define the new needed values from the total array. How to store this total array to get the best performance. Redis, direct from DataBase (MongoDB), somehow else?(backend stateless) flow: user action on frontend --> callback call --> ajax --> here I need to get the new data as described --> getting new data from total array --> ajax returns --> source.change.emit() the bold marked part is stored in REDIS atm (Coding with python). The callback takes some seconds when there are multiple graphs/lines within a chart (around 1sec for each arrays with a size of 3 million values). Is there a way to imporve this speed in general. -
Only want to call a view(not to return anything) using ajax in django
I have a button on my homepage. I want this button to call the view named "request_twitter". Just call it, nothing wants to return. I have developed the code from questions asked on this platforms but still I am not able to call that view. Here is my code view.py def request_twitter(request): global screenname if request.method == 'POST': screenname = request.POST['screenname'] user = validator(request) #this is checking if user is login or not. if he is not login then it will redirect him to login page eg twitter oauth if user: api = get_api(request) user = api.get_user(screenname) try: sn = user.screen_name except: sn = '' try: disply_name = user.name except: disply_name = '' try: descriptin = user.description except: descriptin = '' try: locatin = user.location except: locatin = '' try: urll = user.url except: urll = '' try: Date_joined = user.created_at except: Date_joined = '' try: twitter_user_id= user.id except: twitter_user_id = '' try: profile_lang = user.lang except: profile_lang = '' try: time_zzone = user.time_zone except: time_zzone = '' try: tweetzz = user.statuses_count except: tweetzz = '' try: followingg = user.favourites_count except: followingg = '' try: followerss = user.followers_count except: followerss = '' try: likess = user.favourites_count except: likess = '' … -
How to connect two registered users in Django
I have a Django 2.1.5 app in which I have created two different forms, onto which registered users can post their requirements, for example : "I need a vehicle to go from point A to B", or "I need to go from D to E tomorrow". And, other users can post their services as in "I have a truck free that can go from A to B" etc. So, I have 2 boards, one is for people who need vehicles, and other where people are posting they have free vehicles. Now, I have two different pages for both boards, and two different forms for each board. Now, if I find a requirement which I can fulfil, then there is a button which says 'Bid your price'. After which, I provide my details and a bidding price for the person asking. Then, this information is to be sent to the original author of that requirement. I need to figure out how to connect these two registered people. Should I just give every requirement and service offer a unique URL? and same for every user ? Or is there any other method ? I am really stumped here on what is the … -
ELI5: What is Django?
I realize that some people are probably rolling their eyes at the question, but believe it or not "a high-level Python Web framework" (official description) is not a really helpful sentence to a beginner. What I know: Python is a language where you write down stuff, and then it just gets executed from top to bottom. There are classes and objects, but its still pretty much from top to bottom. There are also libraries, which you can use with include time for example. Those give you a bunch of extra functions, that you don't have to write yourself. Python code is saved in .py files. And now my question - is Django just a fancy python library, or is it an actuall programming language, which for some reason also uses .py files? And how does it work with the {{some_variable_name}} commands I write in my .html files? Is it also Django? Please (if this question does not get removed) pretend that I am really really stupid and know absolutely nothing aside from what I just wrote. Thanks in advance! More context: I have to use oTree, which is a piece of software for economic experiments. And while it is fairly … -
How to force permission check on overwritten post method of UpdateModelMixin?
I'm forced to write some messy work, I need to create partial_update view, however it must use POST method, because the software in the end does not use PUT/PATCH methods. Here are some assumptions: everything needs to be routed via DefaultRouter() in urls.py - that's why I'm using GenericViewSet must use POST method for updating one field - that's why I'm overwriting post() method of UpdateModelMixin instance.visible is a Boolean, which state is set to True as soon as the body is not empty. Update works, except the permission_classess which are ignored. It totally does not check the request for valid credentials. I think it's because I totally overwrote the post(), right? How do I force authentication check within the post method? urls.py: from django.urls import include, path from rest_framework import routers from browse.views import * router = routers.DefaultRouter() [...] router.register(r'update-article', UpdateArticleBodyViewSet) urlpatterns = [ path('api/', include(router.urls)), path('api-auth/', include('rest_framework.urls', namespace='rest_framework'),) ] views.py: class UpdateArticleBodyViewSet(mixins.UpdateModelMixin, viewsets.GenericViewSet): queryset = Article.objects.all() serializer_class = ArticleSerializer permission_classes = (permissions.IsAuthenticated, ) def post(self, request, pk): instance = get_object_or_404(Article, pk=pk) instance.body = request.data.get("body") if instance.body: instance.visible = True instance.save() serializer = self.get_serializer(instance=instance, data=request.data, partial=True) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) -
Django - Nested loops and template rendering with Forms
Is there a way to set a variable after a return statement? I am trying to execute a for loop with a if clause. At first the if clause is False and after the for loop is executed completely it should render a template with a form and then set the variable to True afterwards. Then the for loop gets executed again but this time it should execute the if statement and submit the Form which is something like ("Are you sure?" and then Continue or Cancel). I tried it with using nested loops (for loop inside a while loop) but the return render statement to render the template with the request is not working with setting the variable afterwards. This is my views.py def file_upload(request): if request.method == "POST": # Wenn CSV Datei valide ist --> Datei hochladen csv_file = request.FILES['file'] csv_file.seek(0) decoded_file = csv_file.read().decode('utf-8').splitlines() reader = csv.reader(decoded_file) updated_list = list() created_list = list() s = False while (True): for row in reader: count += 1 try: datet = datetime.now().date() datum = datet.strftime("%d.%m.%Y") row[7] = datum row[8] = str(request.user) #d = [row[0], row[1], row[2], row[3], row[4]] dataset1 = CSV5.objects.filter(gebaeudebereich=row[0], gebaeudenummer=row[1], ebene=row[2], raum=row[3], dose=row[4])#.values_list("gebaeudebereich", "gebaeudenummer", # "ebene", "raum", "dose") dataset2 … -
django safe template filter customization
i'm using a rich text editor for users comments reply. but i need to limit html tags which users type in text editor for avoiding xss attacks. i know that safe template filter is best choice. but as a example i'd just accept some tags like <p>,<a>,<h3> not img,script,... . the problem is that safe filter accepts all of html tags. i'm looking for some thing like this: {{user.reply|safe:'<p>,<h3>,<a>'}} which reply is client's richtext html tags. and safe flter just accepts p,a,h3 tags. i,m using froala rich text editor and also i know to limit text editor options. but if user try to insert some <script> tag it can't undrestand. how can i customize safe filter? or which filter is more appropriate for this job? -
Match two profiles in Django framework
I made a web app which consists of two categories(let's say A and B) of users and there is a common board upon which they can both post something. Now if a person(John) from category A is suggested that his best match is person(wick) from category B by a django card, how can I make something that notifies both of them. Suppose JOHN like what WICK is offering and there is a book button he sees on WICK's card(mini profile). Now I want to notify Wick that JOHN is interested in you when JOHN clicks on the Book button. example data Manufacturer M_ID From To M_Type T_Type T_Length T_Weight #Trucks JOHN A B Boxes Open 12-Tyre 22 3 BLAKE C D Cylinders Trailer HIGH 23 2 GREG G H Scrap Open 14-Tyre 25 5 Transporter T_ID From To T_Type T_Length T_Weight #Trucks Price WICK A B Open 12-Tyre 22 5 1500 PATEL G H Open 14-Tyre 25 10 1200 NICK A B Open 12-Tyre 22 7 1900 The algo returns data in this format Manufacturer Best Match Second Best JOHN WICK NICK GREG PATEL - I can show JOHN that his best matches are WICK and NICK( and when he … -
Disabling options in django-autocomplete-light
Just started using django-autocomplete-light (autocomplete.ModelSelect2) and while I have managed to get it working, I wondered if it is possible to pass disabled options? I have a list of customers to choose from but some, for various reasons, shouldn't be selected they shouldn't be able to use them. I know I could filter these non-selectable customers out, but this wouldn't be very usable as the user might think that the customer isn't in the database. If so, could someone point me in the right direction as I'm not sure where to start. It says in the Select2 documentation that disabling options should be possible. Presumably if I could also send a 'disabled':true within the returned json response that might do it. -

Designing a multi-type user webapp in django
Im building a webapp in django and really beating myself over the design im going to use. This is a big project and it needs to be scalable and so the design is critical. My app will have two main types of users, each of them have to see some similar elements, but their 'Flow' through the website and the interaction with it should be different depending on the user type. I read the answer here and considered using this skeleton project. But non of them address the fact that I have 2 different types of users. And so my question is: is it best practice to have a user/profile app, then app for each one of the entities. or on the other hand have a user app that contains all user related and have user groups deciding which kind of user it is, then the main app will decide which flow to show the user depending on its group. Any other design best practices will be great. -
How to pass more than one parameter from views.py to forms and get them in forms.py in django 2.1.7?
I am new to Django and I am trying to add comments for a post in a blog in Django 2.1. When I want to add comments to a post, I need to save the user who adds the comments and post_id with that comment. I defined my comment model with relations to post and user models. I used init() method for CommentForm and get the post_id, but I can't get user_id similarly in forms.py. Is it possible to pass more than one parameter from views.py and pass it to form and get them in that form to save to that table?

Django forms dynamic getting author as a logged in user in model forms
I'm trying to make some forms that will allow users to add some objects, delete them or edit but I've stucked with thing like author of model. Let's say we got model Shot which got field author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) and then we creating modelForm, creating views etc. and finally got form. When we will try to submit this form, it won't add this object submited in form to db because form has no filled field author author which means this field == Null and that's why it won't add this to db. So my question is how to get it dynamic, for example when user with nick "thebestuser" will try to add this modelForm it will work and mark author as "thebestuser"? Ofc I could add to form field author, but it's the worst way in my opinion and every user would be allowed then to add object for example as a another user, let's say user with nick "anothernick" could add form as a user with "thebestuser" which is In my opinion not acceptable. models.py from django.db import models from django.contrib.auth.models import User from streamers.models import Streamer from django.conf import settings from django.utils import timezone class Shot(models.Model): author … -

But when I give a dictionary with models instances, serializer.is_valid() returns False. data = {'tag_id': 9, 'spending_id': 17} serializer = TagspendingSerializer(data= data) serializer.is_valid() True serializer.save() => ValueError: Cannot assign "9": "Tagspending.tag_id" must be a "Tag" instance. data = {'tag_id': Tag.objects.get(tag_id= 9), 'spending_id': Spending.objects.get(spending_id= 17)} serializer = TagspendingSerializer(data= data) serializer.is_valid() => False Here's my model : class Tagspending(models.Model): tag_id = models.ForeignKey(Tag, models.DO_NOTHING, db_column='tag_ID', primary_key=True) spending_id = models.ForeignKey(Spending, models.DO_NOTHING, db_column='spending_ID') class Meta: managed = True db_table = 'TagSpending' unique_together = (('tag_id', 'spending_id'),) Here's my serializer : class TagspendingSerializer(serializers.ModelSerializer): class Meta: model = Tagspending fields = ('tag_id', 'spending_id') -
