Django `UniqueConstraint` exception handled the same as 'unique=True'
When UniqueConstraint of a model is violated, an exception is raised. How can I make it to behave the same as violation of a field with unique=True? identifier = models.CharField("id", max_length=30, unique=True, blank=True, null=True, validators=[validate_id]) class Meta: constraints = [ models.UniqueConstraint( Lower("identifier"), name="id_case_insensitive_constraint" ) ] Here I want a form's form_invalid called with the same field errors and all that, whether the input is exactly the same as another one or its only difference is case distinction. -

Get queryset objects grouped by an annotation value range
I need to filter my objects in a way to get them grouped by range (range is fixed, for this case let's say we have these 3 ranges [0.0, 33.0] [33.01, 66.0] [66.01, 100.0] here is my model class Item(models.Model): name = models.CharField( help_text="Itemname", max_length=256 ) price = models.DecimalField(max_digits=6, decimal_places=2) I am trying to get a result that looks like this { "0.0-33.0": { name: x, }, "33.01-66.0": { name: y, name: z, }, } I tried something like this: item_by_range = Item.objects.filter(price__lte=100.0).annotate( price_group=Case( When(price__range=[0.0, 33.0], then=Value('0-33')), When(price__range=[33.01, 66.0], then=Value('33-66')), When(price__range=[66.01, 100.0], then=Value('66-100')), default=Value('No group'), output_field=CharField(), ) ).values('name', 'price_group').order_by('price_group') but this only works if I pass only price_group in values but this way I lose the name of the item thanks. -
Can you use session authentication with token authentication? Django Rest Framework
I’m using Django token based auth for my mobile app (react native) and I’m able to log in successfully. I’m also using the Spotify api which I have to open the browser (safari) to log in then it’ll redirect me back to a url in my backend Django-Rest then redirect me back to my react frontend. My issue is that I have to set a redirect uri for Spotify but can’t attach my auth token to it. So after I log into Spotify in the browser and it redirects to the url, I get a 401 error bc it won’t recognize the current user. Is there a way to store the token/current user in cookies/session so the browser will remember who the user is? Do I use session authentication?? Can I/Do I use both token and session authentication? Appreciate any help! Can provide more info if it’ll help -
Given that both the functions are asynchronous, how to ensure that the second function executes after the first function has completely executed
I am learning django and I am stuck with this problem. I wrote a code that uses a function two times. Here is the code snippet. rjl = run(["gnome-terminal", "--", "sh", "-c", f"ffmpeg -i {video_name}_audio_stripped.mp4 -i {audio_name} -c:v copy -c:a aac {final_tutorial}"], cwd="media/") while True: print("frgd") if(rjl.check_returncode()==None): print("wdcv") #for i in range(1000000000): # continue run(["gnome-terminal", "--", "sh", "-c", f"ffmpeg -i {final_tutorial} -vcodec libx265 -crf 28 reduce_{final_tutorial}"], cwd="media/") break else: print("ygbhb") So, the function is run(). Please note that run is subprocess.run. The second run() uses the output generated by the first run function as input. Since run() is asynchronous the second run() executes before the first run() has produced the desired output. In this case, the first run() produces a .mp4 file in the media folder. I made some changes in the code as you can see to solve this problem but still the problem remains. Can someone please suggest me what should I do? I am a newbie and some help will be appreciated. -

serializer increases the query in django rest framwrork

Django - How to update the status of one model in the save method of another model
I have two models ''' class JobPosition(models.Model): ... position_status = models.CharField(choices=POSITION_STATUS) class Outreach(models.Model): ... outreach_status = models.CharField(choices=OUTREACH_STATUS, max_length=20) position = models.ForeignKey('action.JobPosition', on_delete=models.CASCADE, related_name='feelers') ''' I want the position_status of jobposition to be, at any time, the highest of the outreach_status of the outreaches that are related to it (feelers). Where "highest" is set by an arbitrary rule of mine that we can ignore. My thinking is to override the save method of the outreach model and make it so that when the status of the outreach changes, I trigger an update status in the jobposition model to update the status of the position. However, I am realizing that within the safe method, the status of the outreach is still not updated in the DB so if I trigger something on the jobposition model, it would not work. Any other idea? I can do everything in the outreach method but it would have to be an ugle function and I was hoping there was a better way within the jobposition model. -

How do I input an image that is already displayed on html?
I'm working with a webcam application and I am trying to integrate it into Django framework. This is the function that takes a photo(it's javascript in static folder): // play sound effect shutter.play(); // take snapshot and get image data Webcam.snap( function(data_uri) { // display results in page document.getElementById('results').innerHTML = '<img id="imageprev" src="'+data_uri+'"/>'; } ); document.getElementById("camera").outerHTML = ""; Webcam.reset(); } This is a fraction from my template: <div id="camera"></div> <button onclick="takeSnapShot()" type="button" id="button1" class="button-1">Take Picture</button> <form action="" enctype="multipart/form-data" method="POST"> {% csrf_token %} <div name="results" id="results"></div> <div class="button-2"> <button type="submit" href="/">Pateikti</button> </div> </form> So after picture taken, it displays an image inside < div > tag which id is "results" And now I want to save taken photograph. So I tried POST method, but when I do that, the template reloads, and the image gets lost. So I believe that's why I'm getting this error window. Also usually POST method used when you want to save files in your server which client uploads, so I'm not sure if this is the best way to do this So my question is: Is there a method to save an image to your server from a template?
