I am trying to use JsonResponse to return data for a successful Ajax request but am unsure how to format the data. data = request.POST[data_from_javascript] # do something with data return JsonResponse(?) I want to send back the data to the Javascript code and say that it was successful so it can run the success function but am unsure how to correctly do so. -
collectstatic --clear skipping instead of deleting
I am trying to update admin static files after upgrading to Django 2.2, but when I run python3 ./manage.py collectstatic --clear --verbosity 3, I see the following output: Skipping 'admin/css/base.css' (not modified) Skipping 'admin/css/changelists.css' (not modified) Skipping 'admin/css/dashboard.css' (not modified) Skipping 'admin/css/forms.css' (not modified) Skipping 'admin/css/ie.css' (not modified) Skipping 'admin/css/login.css' (not modified) ... I would think that using the --clear option would prevent skipping any files. How can I force delete? These static files are served on AWS S3. I am able to update modified static files just fine, and the --clear option worked prior to the upgrade. I am using the following relevant packages: Django==2.2.3 django_storages==1.7.1 boto==2.49.0 settings.py from boto.s3.connection import OrdinaryCallingFormat ########## AWS CONFIGURATION AWS_STORAGE_BUCKET_NAME = 'xxxxx' AWS_S3_REGION_NAME = 'xxxxx' AWS_S3_CALLING_FORMAT = OrdinaryCallingFormat() AWS_S3_CUSTOM_DOMAIN = '%s' % AWS_STORAGE_BUCKET_NAME AWS_S3_HOST = 's3-%s.amazonaws.com' % AWS_S3_REGION_NAME STATIC_ROOT = normpath(join(SITE_ROOT, 'assets')) STATICFILES_DIRS = ( normpath(join(SITE_ROOT, 'static')), ) STATICFILES_FINDERS = ( 'django.contrib.staticfiles.finders.FileSystemFinder', #'django.contrib.staticfiles.finders.AppDirectoriesFinder', #causes verbose duplicate notifications in django 1.9 ) STATICFILES_LOCATION = 'static' STATIC_URL = "https://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, STATICFILES_LOCATION) STATICFILES_STORAGE = 'custom_storages.StaticStorage' -

How to refresh an item in a flatList when like action happened?
So I have a flatList that gets data from an API. It does not refresh itself automatically not even with extraData. So I just want that the picture on that post changes to the LIKED picture. I already tried that in the likeAction function inside the StandardPostView that it gets refreshed by the response data, but then all the new / or next posts got the same LIKED picture. constructor(props) { super(props); this.state = { gestureName: 'none', hasLiked: this.props.has_liked, count:this.props.likes, current_user:"", modalVisible: false, dropdown:"", }; } likeAction = () => { axios.get(URL+'/api/posts/like/'+this.props.post_id, {headers: {'Authorization':'Token '+this.props.jwt}}) .then((response) => { }).catch((error) => { this.setState({ error: 'Error retrieving data', }); }); } return ( <Text style={styles.date}>{format(new Date(this.props.date), 'MMMM Do, YYYY')}</Text> <View style={styles.likeSection}> <TouchableOpacity onPress={this.likeAction}> <Image style={styles.likeImage} source={image_url}/> </TouchableOpacity> <TouchableOpacity onPress={this.props.goToUser}> <Image source={require("../icons/share.png")} style={styles.share}/> </TouchableOpacity> </View> </View> ); } } <StandardPostView current={this.state.user} author_id={item.author.id} username={item.username} title={item.title} content={item.content} image={{uri:item.author.profile_image}} date={item.date_posted} handleRefresh={this.handleRefresh} likes={item.likes} post_id={item.id} jwt = {this.props.screenProps.jwt} refresh = {this.handleRefresh} has_liked = {item.has_liked} editPost={() => this.props.navigation.navigate('EditPost',{ title:item.title, content:item.content, post_id:item.id })} goToProfile={() => this.props.navigation.navigate('UserProfile', { user_id:item.author.user })} goToPost={() => this.props.navigation.navigate('SinglePost', { post_id:item.id })} goToPostLike={() => this.props.navigation.navigate('PostLikes', { post_id:item.id, title:"Likes" })} goToUser={()=> this.props.navigation.navigate('ChooseUser',{ post_id:item.id })} /> )} /> -

Using django-user-accounts with costom PasswordChangeView - Rediect Error
I'm setting up a django project and I need a user-management-system that follow our user policy. It needs to force the user to change the password after 180 days. So I decided to use pinax/django-user-accounts. I have a own django app named 'accounts' that customize the standard django auth behaviour - essantially defining custom templates. When the password expires, django redirects to /accounts/change-password/?next=account_password and so it loops and a browser redirect error shows up in my Firefox. I setup django-user-accounts: ACCOUNT_PASSWORD_EXPIRY = 60*60*2 # seconds until pw expires ACCOUNT_PASSWORD_USE_HISTORY = True ACCOUNT_LOGIN_URL = 'accounts:login' ACCOUNT_LOGOUT_REDIRECT_URL = 'accounts:logout' ACCOUNT_PASSWORD_CHANGE_REDIRECT_URL = 'accounts:account_password' SITE_ID = 1 I also tried to hardcode the ACCOUNT_PASSWORD_CHANGE_REDIRECT_URL to '/accounts/change-password'. The result was the same. The login_required-decorator was changed from django.contrib.auth.decorators to account.decorators. The urls.py of my accounts app is: app_name = 'accounts' urlpatterns = [ ... path( 'change-password/', MyPasswordChangeView.as_view(), name='account_password' ), ] I'm created my own password change view inherits from django.contrib.auth.views.PasswordChangeView: class MyPasswordChangeView(PasswordChangeView): template_name = 'accounts/password_change.html' def get_success_url(self): return '/' The goal is to show up the change-password/ page on every request if the password is expired. It allready tries to get there, but ends up in this redirect loop. -
How to set a postgres table default ID to uuid_generate_v4() with Django
I have been told to set all the table default IDs in my Django project to the value of the postgresql method uuid_generate_v4(). An example of the current models I'm using is: import uuid from django.db import models class MyModel(models.Model): class Meta: ordering = ("my_var",) id = models.UUIDField(primary_key=True, default=uuid.uuid4, blank=True, editable=False) my_var = models.CharField(max_length=64, unique=True) I have come to understand that it would not be advised to mix SQLAlchemy with Django, so how can I best implement what is asked of me? (Note: yes, default=uuid.uuid4 isn't enough for what my project requires) -
Django creates new cart-product instead of updating already existing object

uWSGI runs Django project from command line but not from Emperor uwsgi.service file
I am running a virtualenv with Python3.6 on Ubuntu 16.04 for my Django project using uwsgi and NGINX. I have uWSGI installed globally and also in the virtualenv.

However I am obviously running uWSGI in "Emperor mode" and when I set the service file up (along with NGINX) the domain displays internal server error. The uWSGI logs trace to --- no python application found --- I was having this problem when running uwsgi --http :8080 --home /home/user/Env/myproject --chdir /home/user/myproject/src/myproject -w myproject.wsgi because it was using the global install uwsgi instead of the virtualenv one.

Mixing Django models and SQLAlchemy in model fields: can it be done?
I have several models, with ids defined like this: id = models.UUIDField(primary_key=True, default=uuid.uuid4, blank=True, editable=False) I want to be able to use the SQLAlchemy server_default option, I tried this way: id = Column( UUID(as_uuid=True), primary_key=True, server_default=sqlalchemy.text("uuid_generate_v4()"), blank=True, editable=False, ) but this returned the error NameError: name 'sqlalchemy' is not defined (despite sqlalchemy being imported and installed with Pip). Is there a clean/correct way of making use of this function in a Django model? -
Is there a way to set two variables as unique together?
I'm creating an application that i have username and nickname for the same person: username = models.CharField( max_length=40, unique=True, db_index=True) nickname = models.CharField(max_length=100, unique=True) But i need to define this two variables as unique like: If an user A has: username: bird nickname: dog and an user B try to make registration like: username: dog nickname: butterfly I will not accept because dog is already taken. Or if an user try to put nickname as same as username. I'm thinking to create a registration view to make this validation manually. But is there a way to make this in the declaration? -

Django values() function. What are *fields?
As documentation says: values(*fields, **expressions) The values() method takes optional positional arguments, *fields, which specify field names to which the SELECT should be limited. If you specify the fields, each dictionary will contain only the field keys/values for the fields you specify. If you don’t specify the fields, each dictionary will contain a key and value for every field in the database table. But what is *fields is not clear to me. Supposing a model named MyModel with just three fields: id, name and phone. This works: values = MyModel.objects.all().values('id', 'name', 'phone') This doesn't work: def get_values(fields): return MyModel.objects.all().values(fields) fields = ['id', 'name', 'phone'] values = get_values(fields) Because it raises: AttributeError: 'list' object has no attribute 'split' But I don't understand why. I mean, it is clear that a list, tuple or set don't have a split method but, is not a list (a tuple, actually) what I am passing in the first example? The second code snippet fails even with a tuple or a set, and this is obvious, because they don't have a split method too. So what type am I passing in first example? There's something about python/django behavior that I'm not missing. Thank you. -
Circular imports django
I have wrote this code in my models.py file. As you see the code, I have a class called File and also I have imported in models.py the same class. Now it gives me this error while migration: Cannot import name "File" from 'uploadapp.models' I understand it's the error for circular (recursive) import. But how can I solve this? from django.db import models from .models import File class File(models.Model): file = models.FileField(blank=False, null=False) def __str__(self): return self.file.name -
Updating source of video tag with ajax
I have an html page where there is a calendar, a video tag and a button. When a user clicks on a button, based on the timestamp the path of the video file from Django is sent and is received by an ajax call. When the page is opened for the first time or is refreshed and the date and time is selected and then the button is pressed the video corresponding to that date and time gets displayed on the page and can be played. However when I change the date and time, the same video file which was opened previously gets displayed on the page, however the path of the video file which is being returned from the django is according to the new date and time. Kindly help me here. HTML code <div style="margin-left: 10%"> <button type="submit" class="btn btn-secondary btn-lg" id="recorded" name="btn_submit" value="Play Recorded Videos" onclick="record()" >Play Recorded Videos</button> </div> <div id="videoDiv" class="container" style="margin-left: 10%; margin-top: 1%; align-items: center; display: none "> <video id='storedVideoId' width='100%' controls > </video> <br><br> </div> Javascript code <script type="text/javascript"> var dateNow = new Date(); dateNow.setDate(dateNow.getDate()); var timer $(function () { $('#datetimepicker1').datetimepicker({ defaultDate:dateNow }); }); function getDataFromServer() { getVideoFile() } function getSelectedDate() { … -
How to manage static files in Python, which are in separate app in Django 2+?
Here is my project directory: So I want to create home.html file where to load style.css file. How I load style.css file in home.html file: {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'style.css' %}"> Which returns me: <link rel="stylesheet" type="text/css" href="/static/style.css"> Which is not the right path. Based on documentation I tried with: {% load static %} <img src="{% static "my_app/example.jpg" %}" alt="My image"> in my case: {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'core/style.css' %}"> But it returns me wrong path again: <link rel="stylesheet" type="text/css" href="/static/core/style.css"> Where am I wrong ?
