Pushing and maintaining backend(Django) and frontend(Angular) folder in one repo
I have searched in google about this many says we can do this in two ways : creating the main repo and having one .gitignore file in there and pushing all in one repo. Maintaining separate git repo i.e for backend separate repo and frontend separate repo. So, I chose second-way i.e maintaining and pushing separate repo and I have structure projects with the backend(Django) and frontend (Angular) folders. But doing that creates a separate GitHub repo and I don't want to have a separate Github repo. What I want: I want to create in one repo with the folders backend and frontend but they should be maintained separately. My questions: How do I maintain and push in GitHub repo with separate backend and frontend folders in one repo? Is there any best practices? Please let me know how can I do it? -
Why is the foreign-key item not connected?
What is wrong with the setup of the models that foreign-key item ('Comment') doesn't seem to be connected? I am working on the Assessment part of Mozilla's Django tutorials and set up a blog-with four models: Post, Author, Comment, Commenter. While I can create posts and posts with comments, comments created separately aren't connected with posts. My code is here and this is following the Mozilla Django tutorial: class Post(models.Model): post_title = models.CharField(max_length=100) author = models.ForeignKey('Author', on_delete=models.SET_DEFAULT, default=None, null=True) description = models.TextField(max_length=1000) comment = models.ForeignKey('Comment', on_delete=models.CASCADE) commenter = models.ForeignKey('Commenter', on_delete=models.CASCADE) class Author(models.Model): author_first_name = models.CharField(max_length=30) author_last_name = models.CharField(max_length=30) author_username = models.CharField(max_length=20) class Comment(models.Model): comment_title = models.CharField(max_length=100) comment_text = models.TextField(max_length=1000) commenter = models.ForeignKey('Commenter', on_delete=models.SET_DEFAULT, default=None, null=True) class Commenter(models.Model): commenter_username = models.CharField(max_length=20) -
Django JSONField query on a list of values where at least 1 value is in the filter list
I have this model: class Movie(models.Model): genres = models.JSONField(default=dict, null=False, blank=False) The data inside this column contains a list of genres e.g.: ["biography", "comedy", "crime", "drama", "romance"] When I try and execute the following code, I get empty: wanted_genres = ['action', 'adventure', 'animation', 'biography', 'comedy', 'crime', 'documentary', 'drama', 'family'] Movie.objects.all().distinct().filter(genres__contains = wanted_genres) I want to get results where at least 1 genre of wanted_genres is found in the column genres.

Nested Serializer Fields Django Rest Framework
I have two models (User and Province) and serializers. The user creates a province and in the province model I have the user id. The challenge is when creating nested serializers, I only want the first_name and last_name from the user but is is giving me everything including the password.

Django Viewset retrieve not working with Default Router

Design Decision - Should Django tests be state-less or state-full?
So, I am facing this dilemma of designing Django unit tests. I can either make the tests so that they do not depend on each other but this would either mean 2 things: I undo what I did in the test itself and for all the tests. I design the tests in such a way that they don't depend on each other. The second options is I can make the tests state-full as in a real use case scenario. A real user generally never undoes what was done before before performing another operation on the database right? Although I agree, state-less tests are in general better due to the fact that more things can be tested in CI as each test is an independent unit, I think for the database tests, state-full might be a better option. Please share your opinion. Thanks A Fellow StackOverflower -
django cross site redirection crsf token security
Ive been trying to integrate a payment method for my website, it requires verification from an external webpage (bank), it requires a response_url, from which the status and dat wil be posted back on my site, when it operates django gives me an error requiring a csrf token for posting a form, I found a workaround setting @csrf_exempt, but I asume its not the optimal solution, since is less secure, what is the correct solution for csrf token solicitaiton when posting from an external page? def pay_started(request): usu = CuentaUsusario.objects.get(usuario=request.user) response_url = 'http://xxx.xxx.x.xx:8000/cuentas/pay_inscr_finish/' if request.method == 'POST': username = request.POST.get('user_name') email = request.POST.get('email') response_url = request.POST.get('response_url') req = request.POST resp = MallInscription.start(user_name=username,email=email,response_url=response_url) return render(request,'c_cuentas/pay_started.html',{'usu':usu,'resp':resp,'req':req}) return render(request,'c_cuentas/pay_started.html',{'usu':usu,'response_url':response_url}) @csrf_exempt def pay_inscr_finish(request): if request.method == 'POST': req = request.POST token = request.POST.get('TBK_TOKEN') resp = MallInscription.finish(token=token) ttoken = resp.transbank_user authoriz_code = resp.authorization_code tarjeta = resp.card_type ult_dig = resp.card_number return render(request,'c_cuentas/pay_inscr_finish.html',{ 'utl_digit':utl_digit, 'tarjeta':tarjeta, 'ttoken':ttoken, 'authoriz_code':authoriz_code}) -
Is there a way to set a context variable's value within js or html when using Django?
I'm working on a website using python django as a back end, and am currently trying to pull values from a HTML form and pass it to a django form. This is due to only certain fields needing access to data from the database and needing JS on the page to show/hide based on the values of certain selects in the HTML. What I need to do is to set the value of an object's attribute that is passed in from the views.py <script> output = document.getElementById("example"); {{ form.fieldImChanging.value }} = output.value; </script> ... <form action="" method="POST" class="row gy-2 gx-3 align-items-center"> <label for="example">TestField</label> <input type="text" name="example" maxlength="16" size=20 required=""> ... <input class="btn btn-success col-3 mt-2" type="submit" value="Submit"> <a href="{% url '*snipped url*' *snipped vars* %}" class="btn btn-secondary col-3 mt-2">Back</a> </form> Where the trouble lies is in getting that context variable to set, because as of right now that will just create a variable named after whatever the default value of fieldImChanging is in the django form. Is there a way to do this with django at all? -

Video with custom controls not Playing on iOS (safari & chrome)
I'm developing a platform with Django which hosts videos that are uploaded directly on a server. I'm testing the app and the result I got is that the videos are playing fine on Desktop but they are not playing on mobile iOS (safari & chrome), instead they are playing in mobile with android 10. The videos follow the proper format (mp4) and encoding standards (H264, AAC). I've read different topics that talk about the proper way to trigger and play a video (ex.1 ex.2) on iOS, but even if I'm following this guideline I'm unable to trigger the video to play when pressing the play button. I've no idea what's wrong with it. Here is the code: <div class="c-video"> <video class="video" id="video" src="{{ video.video.url }}" type='video/mp4' poster="{{ video.image.url }}"> </video> <div class="controls"> <div class="bar"> <div class="dragger"></div> <div class="barline"></div> </div> <div class="buttons"> <button id="play-pause"></button> </div> <div class="volume-slider"> <input id="vol-control" type="range" min="0" max="100" step="1" oninput="SetVolume(this.value)" onchange="SetVolume(this.value)"></input> </div> </div> </div> <script> var video = document.getElementById("video"); var btn = document.getElementById("play-pause"); btn.addEventListener('click', function(e) { if (video.paused || video.ended) video.play(); else video.pause(); }); </script> I've also tried to trigger the play event directly from the button as follow but nothing changed: <div class="buttons"> <button id="play-pause" onclick="togglePlay();"></button> … -
export table contain image in python django

Why is collectstatic adding back files I deleted to my Wagtail project?
So I'm deploying a Wagtail project to a droplet on DigitalOcean and the collectstatic step keeps failing because of a post-processing failure. I didn't need the directory that was failing, so I removed it from my project. But somehow that old directory keeps coming back every time I try to run collectstatic and the post-processing keeps failing on a file that no longer exists but seems to be haunting my server somehow. Here are the things I have tried: Deleting the static directory entirely Deleting the offending directory from my repository and running git clean to remove all untracked files from my server Deleting my entire project directory, creating a new virtualenv and cloning a fresh copy of my project with the offending directory removed Logging off my server and logging back on again Running collectstatic --clear (which doesn't seem to delete anything when I run it) Quitting terminal and restarting that, then logging back onto my server Destroying my entire droplet then creating a new one, creating a new virtualenv and cloning a fresh copy of my project without the offending directory in it. Whenever I run collectstatic, it still is somehow adding back the offending directory I deleted … -
Django Class based Form only updating the final post value

Django - Can I add a calculated field that only exists for a particular sub-set or occurences of my model?
Imagine that you have a model with some date-time fields that can be categorized depending on the date. You make an annotation for the model with different cases that assign a different 'status' depending on the calculation for the date-time fields: #Models.py class Status(models.TextChoices): status_1 = 'status_1' status_2 = 'status_2' status_3 = 'status_3' special_status = 'special_status' class MyModel(models.Model): important_date_1 = models.DateField(null=True) important_date_2 = models.DateField(null=True) calculated_status = models.CharField(max_length=32, choices=Status.choices, default=None, null=True, blank=False,) objects = MyModelCustomManager() And the manager with which to do the calculation as annotations: # managers.py class MyModelCustomManager(models.Manager): def get_queryset(self): queryset = super().get_queryset().annotate(**{ 'status': Case( When(**{'important_date_1' is foo, 'then': Value(Status.status_1)}), When(**{'important_date_2' is fii, 'then': Value(Status.status_2)}), When(**{'important_date_1' is foo AND 'importante_date_2' is whatever, 'then': Value(Status.status_3)}), # And so on and so on ) } ) return queryset Now, here's where it gets tricky. Only one of these sub-sets of occurrences on the model requires an ADDITIONAL CALCULATED FIELD that literally only exists for it, that looks something like this: special_calculated_field = F('important_date_1') - F('importante_date_2') #Only for special_status So, basically I want to make a calculated field with the condition that the model instance must belong to this specific status. I don't want to make it an annotation, because other instances … -

Heroku config variables visible via CLI but not via code
I have set config vars for a free-tier Django app on Heroku. They can be seen via the CLI and at the settings page on Heroku. I set the DISABLE_COLLECTSTATIC variable to 1, for example, so that git push to Heroku would finish successfully (and it did). However, I cannot access the variables from code via Python’s os.environ, and $ env via Heroku’s ps:exec does not show them, including DISABLE_COLLECTSTATIC. These variables are not specific to a particular third-party’s add-on. They are named only with alphanumeric characters and the underscore character. I created a Django beginner’s tutorial app to reduce the problem to a minimum and then test it but got the same result.
