How to restrict access by group membership, roles, and ID in Django using class-based views
I'm a relative newbie, working on a Django directory-based app that serves many companies, and I want to know best practices/standards for restricting access by company-membership, user ID, and user role. The app is structured so that a company manager (CM) has superuser-like permissions for that company only, and then company team members (CTM) may or may not have restricted permissions to modify pages specific to that group/company only. The public user needs to be able to access the company's pages so companies are separated using their slug in the url. So company "A"'s home page is found by example.com/A/home. Using LoginRequiredMixin effectively restricts access to only logged-in users but logged-in users can be of the following types in this app: a public member, an app admin (like myself), a company manager, a company team member. I need to make sure of the following: 1) the logged-in user belongs to the company that is trying to be accessed (ie if I am a public user or belong to company "B" I cannot access company "A" restricted pages simply by being logged in and entering the slug in the url), 2) the logged in user has necessary permissions, even if the … -

Django TemplateDoesNotExist - moving working project from windows to linux
I am working to move a Django project from windows to linux. It works great in windows, but I am running into all sorts of errors trying to get it running on linux. The current issue I am facing is saying the template cannot be found. I have tried all the recommendations I can find online so I am looking for a little help. Furthermore, I am a little confused because one of the directories it says it is looking in which has the actual file, Django still does not see it. Here is part of the error in the picture showing which directory it looked at to find the file. The file is actually in this directory, so I am not sure what is going on. One thing I noticed is the back slash is incorrect, not sure where this directory is located in the code to fix this? django.template.loaders.filesystem.Loader: /home/pi/Desktop/MarketJungle/project_settings/templates/Website\base_template.html (Source does not exist) Settings.py Error -
Django BooleanField(default=False) Confusion
Can anyone help me out here? I am inserting data into my postgreSQL DB. admin_created is a booleanfield set to false by default. I've provided a true value for the first workout, but left the second workout blank for the booleanfield. Based on my understanding it should automatically be set to false, but i'm getting the error message below. Any ideas on why this is happening? #.sql INSERT INTO main_app_workout(name, description, admin_created) VALUES ('Yoga', 'Roll up your yoga mat and discover the combination of physical and mental exercises that have hooked yoga practitioners around the globe.', 'True'); INSERT INTO main_app_workout(name, description) VALUES ('Boxing', 'Ready to get your sweat on?

TypeError: data.map is not a function, even though the data is an array (i think)
Im using Django rest to send data to react: [ { "id": 1, "username": "Dewalian", "question": [ { "id": 5, "title": "how to cook?" }, { "id": 6, "title": "how to exercise?" } ] }, { "id": 2, "username": "Edward", "question": [] }, { "id": 3, "username": "Jeremy", "question": [] } ] and then fetch it using a custom hook from a video tutorial: import useFetch from "./UseFetch"; import DataList from "./DataList"; const MainContent = () => { const {data: question, isPending, error} = useFetch("http://127.0.0.1:8000/api/user/"); return ( <div className="main-content"> {error && <div>{error}</div>} {isPending && <div>Loading...</div>} {question && <DataList data={question} />} </div> ); }; export default MainContent; finally i map it on another component: const DataList = (data) => { return ( <div> {data.map(user => ( <div key={user.id}> <p>{user.username}</p> </div> ))} </div> ); } export default DataList; but i get "TypeError: data.map is not a function".

Reducing the number of queries in a Django app using a raw query
Objects of MyClass have associated history table that is populated by the database triggers, so not under control of the application. Current code has a method to query the history: class MyClass: @classmethod def history_query(cls, id): query = f'select * from history_table' if id: query = f"{query} where id='{id}'" def history(self): return MyClass.objects.raw(self.history_query(self.id)) The problem is when I list all the objects, the history table gets queried once for every object, creating thousands of queries... I'm trying to speed up the sluggish application by changing this to one query. Here's my current attempt: class MyClass: _full_history = None @classmethod def history_query(cls, id=None): query = f'select * from history_table' if id: query = f"{query} where id='{id}'" def history(self): if self._full_history: return self._full_history[self.id] return MyClass.objects.raw(self.history_query(self.id)) @classmethod def history_by_id(cls): if cls._full_history is None: history_list = MyClass.objects.raw(cls.history_query()) history_dict = {} for item in history_list: id = item.id history_dict[id] = history_dict.get(id, []) history_dict[id].append(item) cls._full_history = history_dict return cls._full_history Is there a better or more efficient way to do this? Would it be possible to do it with prefetch? -

speech recognition in multiple form fields in django
Im using localhost server for my website. I have integrated speech recognition in my form fields. As I needed speech recognizer in every field of form therefore I used different view function for that and rendering back to same page. The speech is working perfectly but the problem is When I submit the form The speech recognition starts working however it should save that data into database. When I donot use speech recognizer it is saving data perfectly but not with speech recognizer as it again starts to run speech algo. I really do not know what should be done at this point.

Django Redirect returns 200, but page does not redirect
I have a django project where I am doing google oauth2. I click on a google signin button, I receive a post request from Googles api, and then I interpret that request and want to redirect the user to a page where they can create their own account. Right now everything appears to work up until the redirect is suppose to happen. The terminal where my django project is running shows that it was successful (the print statements I wrote to confirm it reaches the render function work, and I see a 200 response also), but I remain on the login page. I am wondering if the redirect and render are happening on another website session, or otherwise somewhere besides where the user is currently on the website? Here is the code for my google webhook: token = request.POST.get('idtoken') print(token) try: idinfo = id_token.verify_oauth2_token(token, requests.Request(), settings.GOOGLE_CLIENT_ID) print(idinfo) print('got past token') google_user_id = idinfo['sub'] google_email = idinfo['email'] try: # authenticates user who already exists as a google signed in user. user_from_sub = User.objects.get(google_sub_id=google_user_id) user = user_from_sub.get_user_object() if user.type == Types.BUSINESS: backend = 'user_accounts.auth_backends.BusinessAuthBackend' login(request, user, backend=backend) # TODO: add auth backend cred elif user.type == Types.CONSUMER: backend = 'user_accounts.auth_backends.ConsumerAuthBackend' login(request, user, … -

Aggregating a windowed annotation in Django
Background Suppose we have a set of questions, and a set of students that answered these questions. The answers have been reviewed, and scores have been assigned, on some unknown range. Now, we need to normalize the scores with respect to the extreme values within each question. For example, if question 1 has a minimum score of 4 and a maximum score of 12, those scores would be normalized to 0 and 1 respectively. Scores in between are interpolated linearly (as described e.g. in Normalization to bring in the range of [0,1]). Then, for each student, we would like to know the mean of the normalized scores for all questions combined. Minimal example Here's a very naive minimal implementation, just to illustrate what we would like to achieve: class Question(models.Model): pass class Student(models.Model): def mean_normalized_score(self): normalized_scores = [] for score in self.score_set.all(): normalized_scores.append(score.normalized_value()) return mean(normalized_scores) if normalized_scores else None class Score(models.Model): student = models.ForeignKey(to=Student, on_delete=models.CASCADE) question = models.ForeignKey(to=Question, on_delete=models.CASCADE) value = models.FloatField() def normalized_value(self): limits = Score.objects.filter(question=self.question).aggregate( min=models.Min('value'), max=models.Max('value')) return (self.value - limits['min']) / (limits['max'] - limits['min']) This works well, but it is quite inefficient in terms of database queries, etc. Goal Instead of the implementation above, I would prefer … -

Using get_children runs into problems with custom Page model and Wagtail
I have a model for pages I want to make with Wagtail, befitting a blog post, so there are some extra fields. This works fine as far as creating and viewing pages, but when trying to iterate through them it becomes an issue. For example, when doing something like: {% for post in self.get_children %}{{ post.date }}</a><br />{% endfor %} This will return the error AttributeError at / 'Page' object has no attribute 'date' Except the child being referred to (there is only one) absoultey has a date attribute, and when viewing the page the date attribute works just as it should. How do I inform Wagtail about custom page models?
