Django query - Database table to slow
I have a complex query that is just taking far too long. I think I have drilled down to the main problem when I execute: Airplay.objects.all().count() The execution time is: 48s The results is: 37428412 The model is: class Radio(Timestamps): name = models.CharField('Name', max_length=255, blank=True) slug = models.CharField('Slug', max_length=255, blank=True) country = CountryField(blank=True) def __str__(self): return '%s - %s' % (self.name, self.country) class Airplay(Timestamps): song = models.ForeignKey(Song, on_delete=models.CASCADE) radio = models.ForeignKey(Radio, on_delete=models.CASCADE) airedAt = models.DateTimeField(blank=True) duration = models.IntegerField() playcount = models.IntegerField(default=1) def __str__(self): return '%s - %s' % (self.song.name, self.radio.name) any ideas how to optimize this? Thanks in advance! -

How to clone the input value when cloning the form in JavaScript
I am trying to save multiple objects in one page using django formset. For example, when I want to input 5 objects in the each form, the "kinds" and "hour" field have different values for all 5 objects, and all 5 objects have the same value for the remaining fields. So I am using the django-formset. So, when cloning a form in django formset, I would like the input value to be cloned as well. After several searches I couldn't find a solution. I read that setting true in the clone method will clone the event handler and even the value, but the entered value will not be cloned. Should I get it in the request.POST method? (For reference, the date field uses the datetimepicker jquery, and the student field uses the chosen jquery that is easy to search in the dropdownlist.) [html] <form class="form-horizontal" method="POST" action=""> {% csrf_token %} {{ formset.management_form }} {% for form in formset %} <div class="row form-row spacer mt-4"> <div class="form-group row"> <label>{{form.date.label}}</label> <div class="input-group"> {{form.date}} </div> </div> <div class="form-group row"> <label>{{form.student.label}}</label> <div class="input-group"> {{form.student}} </div> </div> <div class="form-group row"> <label>{{form.kinds.label}}</label> <div class="input-group"> {{form.kinds}} </div> </div> <div class="form-group row"> <label>{{form.hour.label}}</label> <div class="input-group"> {{form.hour}} </div> </div> … -
Need help: whitenoise seems to be preventing a Django app running on heroku
Please point me to the right direction with a Django app that I am trying to put on Heroku. The app runs locally (both with python manage.py run server and heroku local), but doesn't run on heroku. It seems the root problem stems from whitenoise and I get errors doing collectstatic. BTW, whitenoise setup was done following the steps here for using whitenoise with Django. (app repo is here.) Through various searches I found this that suggests setting the Node version on Heroku to use the same one used locally, but I am not using npm nor node. I tried the kill process tip from here, but that didn't help. Neither did heroku restart. Doing python manage.py collectstatic --noinput got me these error messages: Traceback (most recent call last): File "/Volumes/Volume2/dev/student_manage_csp/manage.py", line 22, in <module> main() File "/Volumes/Volume2/dev/student_manage_csp/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/core/management/__init__.py", line 425, in execute_from_command_line utility.execute() File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/core/management/__init__.py", line 419, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/core/management/base.py", line 373, in run_from_argv self.execute(*args, **cmd_options) File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/core/management/base.py", line 417, in execute output = self.handle(*args, **options) File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py", line 187, in handle collected = self.collect() File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py", line 134, in collect raise processed whitenoise.storage.MissingFileError: The file 'admin-lte/plugins/pdfmake/FileSaver.min.js.map' could not be found … -

How can I unit test saving user input in Django?
I am working on a small project and I want to be able to test the post methods, saving to the database if the email does not exist, and rendering to index.html for the view below.

How to change the field name of Serialzed User Model on frontend in Django Rest Framework?
I am making a simple Login/Logout App using REST API in Django DRF. I am using the default User model for this behavior. In the Login API, I wanted to authenticate the user with email, hence I wrote the custom authentication using ModelBackend. Everything works fine. But, I want to change the word username to email in the front of the Login API. I tried using the source attribute, but it does not change. Is there any easy way to do it? I am looking for something like verbose_name, that is used in Django Models. My serializers.py is: class LoginSerializer(serializers.Serializer): username = serializers.CharField(source='Email') password = serializers.CharField() def validate(self, data): user = authenticate(**data) if user and user.is_active: return user raise serializers.ValidationError('Incorrect Credentials Passed.') Again, I am using the default User Model, and I don't want to overwrite/override/extend the User Model. I just want to change the name of the field username on the frontend to be shown as email. Any help will surely be appreciated. -
Passing a Dictionary from Django view to a Django template
I am trying to pass the following context from views.py to a Django Template: views.py: def home(request): context = { 'dict_1': {'key_1': ['val_11', 'val_12'], 'key_2': ['val_21', 'val_22']} } return render(request, 'app/home.html', context) home.html: <script type="text/javascript"> var java_dict = {{ dict_1 }}; console.log(java_dict); </script> This throws an error: Uncaught SyntaxError: Unexpected token '&' Upon investigating, I see that the dictionary in javascript is read as follows: {&#39;key_1&#39;: [&#39;val_11&#39;, &#39;val_12&#39;], &#39;key_2&#39;: [&#39;val_21&#39;, &#39;val_22&#39;]} which probably means that the quotes-character (') is read incorrectly. How do I fix this issue? -
How to fix python manage.py error messages

Django- Incorporate django-sites with multiple models
I am trying to build a white labled product and I am thinking to use django-sites module. I have multiple models of a particular site. I have found an example like add foreign key of a Site model to a single model. but adding foreign key of Site model to each and every model in every api call, I don't think is a best practice. Is there any other way to define once and it will add automatically Site id like we use abstract classes for created_at and so on. Thanks. -

Django - how to access local audio files in different URL paths?
Thanks in advance for reading. I'm working on my final project for CS50W which involves working with a series of local audio files (user cannot upload additional files at this time). The issue occurs when I try to populate an src attribute with the file. I have two URL paths which deal with accessing these files: new/ and edit/int:id. When I access the audio files in new/, it works as intended and I can play the file from the tag. However, when I try to access the files in the edit/int:id path, I get this error: GET http://localhost/edit/8/media/Aminor_Ipi3udk.mp3 net::ERR_ABORTED 404 (Not Found) I am relatively new to coding (just did CS50x and then started CS50w) and I don't understand why I'm getting this error or how I can fix it - I'm doing the same thing for both paths and yet it only works in one of them. I would be grateful if someone could help me to remedy this or at least point me in the direction of understanding why this is happening.
