Django Cannot upload images and get it to update the DB
So I'm trying to make it possible for users to update their Avatar/Profile image by allowing them to upload their image + I want to implement an image cropper so they can crop the image to a ratio of 1 to 1. All tho I think the first thing is making it possible to upload. I've searched around trying to make it possible but I think I've almost been everywhere. The thing is the image field I'm using is like an extension to the User table I basically called it extendeduser that has all the extra information included in it. View.py @login_required def useravatar(request, user_pk): if request.method == 'POST': form = UpdateProfileForm(request.POST, request.FILES, instance=request.user) if form.is_valid(): user = form.save() user.refresh_from_db() user.extendeduser.avatar = form.cleaned_data('avatar') user.save() messages.success(request, 'Your avatar was successfully Uploaded!') return redirect('useravatar', user_pk=request.user.pk) logged_in_user = get_object_or_404(User, pk=request.user.pk) requested_user = get_object_or_404(User, pk=user_pk) driverslicence = DriversLicenceCategories.objects.all() feedback = FeedbackSupportForm() password = PasswordChangeForm(request.user) avatar = UpdateProfileForm(instance=request.user) context = { 'avatar' : avatar, 'logged_in_user': logged_in_user, 'requested_user': requested_user, 'feedback' : feedback, 'password' : password, } return render(request, 'user/avatar.html', context) Models.py class ExtendedUser(models.Model): avatar = models.ImageField(upload_to='users/avatars', default='static/img/userpreload.png') background = models.ImageField(upload_to='users/backgrounds', default='static/img/userpreload.png') Forms.py class UpdateProfileForm(forms.ModelForm): postal_code = forms.CharField(max_length=10, required=True) phone_number = forms.CharField(max_length=16, required=True) phone_number_show = forms.BooleanField(required=False) avatar … -
matching query does not exists - error in Django search
I have been struggling with this for a while now.I tried to implement Django search with pagination. Pagination works, but when I try to search something, I get this error: Course matching query does not exist.

Django : "stream" vs request.FILES["file"]
So I wanted to write a custom file upload parser as specified in docs. According to doc I implemented the parse method as class MailParser(BaseParser): """ parses email serialized data """ media_type = "multipart/form-data" def parse(self, stream, media_type = None, parser_context = None): """ Here I was trying to read stream """ but when I tried to read stream it additionally had following content ----------------------------488071469102781097692083 Content-Disposition: form-data; name="file"; filename="email_test.msg" Content-Type: application/vnd.ms-outlook < actual content here > ----------------------------488071469102781097692083-- But when I directly read the file from request using request.FILES['file'] .read() The same content wasn't there. I wanted to understand this behaviour. Thanks in advance. -
NoReverseMatch at /login/
NoReverseMatch at /login/ is the error I'm getting from the console, I have a feeling this is something to do with the linking that is going on between urls.py but I can't figure out which part of it is wrong.

Django annotate with conditional expression, how to apply distinct()
I have a little bit complex query and I use annotate with a conditional expression, the code is below: from django.db.models import Q, F, When, CharField, Value, Case from django.contrib.auth.models import User ATT_PREFIX = 'f' def get_it(mymodel, fields): q = Q(modelone__modeltwo__mymodel=mymodel) query_set = { 'aid': F('modelone__id'), 'name': F('modelfour__name'), } for f in fields: query_set[ATT_PREFIX + str(f.id)] = Case( When(Q(modelfive__modelsix=f) & Q(modelfive__user__email=F('email')), then='modelfive__entry'), default=Value(''), output_field=CharField(), ) return User.objects.filter(q).annotate(**query_set) Attributes aid and name collected with F() have expected values. Second part which use conditional expression have a problem: If feilds list contain 2 objects, then I have 2 User objects created by Case() when condition is meet. So instead of one object with atributes (aid, name, f17, f18) I got two objects: obj1 attributes (aid, name, f17) obj2 attributes (aid, name, f18) -

Django - User uploaded S3 files in the view
I have a page where users can upload PDF / image files to their profile. The model for these files is relativly straightforward: class ResumeItemFile(models.Model): item = models.ForeignKey(ResumeItem, related_name='attachment_files') file = models.FileField( max_length=255, upload_to=RandomizedFilePath('resume_attachments'), verbose_name=_('Attachment')) name = models.CharField(max_length=255, verbose_name=_('Naam'), blank=True) I am creating a view where all files linked to a profile (item) are gathered in a .zip file. I've got this working locally, but in production I run in the following error NotImplementedError: This backend doesn't support absolute paths. The main difference is that on production the mediafiles are served through S3 MEDIA_URL = 'https://******.s3.amazonaws.com/' STATIC_URL = MEDIA_URL In my view I created a list of the ResumeItemFile in the attachments variable, which is a list of dicts that look like this: {'filename', ResumeItemFileObject} for file in attachments: storage = DefaultStorage() filename = file[1] file_extension = str(file[0].file).split('.')[-1] file_object = storage.open(file[0].file.path, mode='rb') filename, file_object.read()) file_object.close() Though this works fine locally, on staging it crashes on the file_object = storage.open(file[0].file.path, mode='rb') line. If the backend does not support absolute paths, how I am to select the correct file? Does anyone have an idea of what I am doing wrong? -
Django : render not passing context variable to template
I have this views function to fetch userid and accountnumber from AWS Dynamodb : def dsctbl2(request): dynamodb=boto3.client('dynamodb', region_name='us-west-2') response = dynamodb.scan( TableName='User-Account') filtered = response['Items'] length = len(filtered) for k in range(length): accnum = filtered[k]['AccountNum']['S'] uid = filtered[k]['UserId']['S'] f = dict(AccountNum=accnum,userID=uid) rows = list(f.items()) return render('useradd.html',{'rows': rows}) I have tried almost everything but the rows value is just not getting passed to my template. I even tried passing a simple string value and even that is not getting passed. This is my template table where I wish to display the userid and accountnum. <div class="mytable"> <table> <thead> <tr> <th>Account #</th> <th>User Id</th> </tr> </thead> <tbody> {% for row in rows %} <tr> <td>{{ row.AccountNum }}</td> <td>{{ row.UserId }}</td> </tr> {% endfor %} </table> </div> When I hit the template , nothing shows up. No values are getting displayed except the table headings. Why is render not passing the context variable (list value)from my views to template ? I have been stuck with for about 6 hours ! Can someone resolve this issue ? -
Django, CSS3, and font-face: how to load local font files?
So I have a Django app <my-app> and I would like to load some local font files into the base template <my-app>/templates/<my-app>/base.html. For example, under <my-app>/static/<my-app>/fonts/Lato/ I have several .ttf files: Lato-Black.ttf Lato-BlackItalic.ttf Lato-Bold.ttf etc and in <my-app>/static/<my-app>/css/fonts.css I have: @font-face { font-family: Lato; font-style: normal; font-weight: 300; src: local('Lato-Black') url('../fonts/Lato/Lato-Black.ttf') format('truetype'), local('Lato-BlackItalic') url('../fonts/Lato/Lato-BlackItalic.ttf') format('truetype'), local('Lato-Bold') url('../fonts/Lato/Lato-Bold.ttf') format('truetype'), local('Lato-BoldItalic') url('../fonts/Lato/Lato-BoldItalic.ttf') format('truetype'), local('Lato-Hairline') url('../fonts/Lato/Lato-Hairline.ttf') format('truetype'), local('Lato-HairlineItalic') url('../fonts/Lato/Lato-HairlineItalic.ttf') format('truetype'), local('Lato-Italic') url('../fonts/Lato/Lato-Italic.ttf') format('truetype'), local('Lato-Light') url('../fonts/Lato/Lato-Light.ttf') format('truetype'), local('Lato-LightItalic') url('../fonts/Lato/Lato-LightItalic.ttf') format('truetype'), local('Lato-Regular') url('../fonts/Lato/Lato-Regular.ttf') format('truetype') ; } Accordingly in base.html: <link rel="stylesheet" type="text/css" href="{% static '<my-app>/css/fonts.css' %}" /> This does not load the fonts so that I can use them as if I used Google's api: <link href="https://fonts.googleapis.com/css?family=Lato" rel="stylesheet"> So how do I fix my CSS? -
pass class variable name to class method
I have a Model defined as below: class ProblemVerificationModel(CreateUpdateDateModel): problem = models.ForeignKey(Problem, related_name="problem_survey") verifier = models.ForeignKey(settings.AUTH_USER_MODEL, related_name="verified_problem") is_problem_properly_formated = ... # BooleanField is_this_done = ... # BooleanField is_that_done = ... # BooleanField # other BooleanFields The above model serves like a voting system in my application. I need to calculate percentage of votes for each property such as is_problem_properly_formated, is_this_done, is_that_done etc. I am using classmethod for the same as defined below: @classmethod def percentage_problem_properly_formated(cls, problem): votes = cls.objects.filter(problem=problem) total_votes = votes.count() yes_votes = votes.filter(is_problem_properly_formated=True).count() percentage_yes = (yes_votes / total_votes) * 100 return percentage_yes @classmethod def percentage_is_this_done(cls, problem): votes = cls.objects.filter(problem=problem) total_votes = votes.count() yes_votes = votes.filter(is_this_done=True).count() percentage_yes = (yes_votes / total_votes) * 100 return percentage_yes Now for each property I am using similar method with difference being parameter passed to filter method. This certainly is not a DRY way of doing things. I just want a single method where I can pass the parameter to pass to filter method. Can you help or provide hints to achieve the same results the DRY way? -

django 2 crud operations without database with external api
I have an external third-party API for retrieving and storing song names and I need to interface it with Django 2 and permit the user through Django forms to insert and update songs. I'm struggling as most documentation on Django assumes a database backend and even examples on consuming an external REST API assume I want to store fetched data from the API to the database. I looked into creating a Django 2 custom model manager but it seems this is used as something above an existing database and not an external API. Django 2 serializers permit to serialize and deserialize data in between an API and a database. What I'm missing is the way to create a custom model abstracting the API and permitting me to use it as if it were a database so that I can go on and follow any Django forms tutorial after having abstracted the model layer. Currently I hacked something like below: urls.py : urlpatterns = [ url(r'^$', viewSong, name='home'), url(r'^create/$', SongView.as_view(), name='create'), url(r'^update/(?P<song_id>[0-9\.a-z]+)/$', SongUpdate.as_view(), name='update'), ] templates/form.html : <form role="form" action="/create/" method="post"> {% csrf_token %} <div class="form-group"> <label for="song-id">Song Id</label> <input type="text" id="song-id" name="song-id"> </div> <div class="form-group"> <label for="son-name">Song Name</label> <input type="text" … -
How to display 3 lists together using Python 3 + django2?
I have a list as follow: item1, [subitems] item2, [subitems] ... itemN, [subitems] For instance, item1 .. itemN might be a list of classes, and [subitems] contains a list of students that attend each class. A student might attend more than 1 class. Each class and student has a description (in a string variable). I want to create a (static) table that contains two columns. The first column is the list of classes. When I click to one element in the first column, the second column will display the list of students attend this class. Also, the description of the class will be displayed. If I click to a student, the cell will expand and display the description of the student. Sorry if the description is not so clear. The idea is as the image following: The list and description are stored in TXT files, not database. -

Trying to display same model with different pagination
So I have this page with 2 columns. First column represents the way I display my courses in the second column. On the second column all my courses are listed and from the first column I can choose how to list specific courses (by faculty) that replaces the all courses on the second column when pressed on faculty name. I added pagination to all courses of the second column which works as intended. Then when I tried to add pagination by faculty, only first faculty will appear and if I press on second page of the faculty courses, it will redirect me to all courses pagination for some reason.. <div id="crs"> <h3>All courses</h3> <ul> {% for course in courses %} <li><a href={{ course.slug }}>{{ course.name }}</a></li> {% endfor %} </ul> <div class="pagination"> <span class="step-links"> {% if courses.has_previous %} <a href="?page=1">&laquo; first</a> <a href="?page={{ courses.previous_page_number }}">{{ courses.previous_page_number }}</a> {% endif %} <span class="current"> Page {{ courses.number }} of {{ courses.paginator.num_pages }} </span> {% if courses.has_next %} <a href="?page={{ courses.next_page_number }}">{{ courses.next_page_number }}</a> <a href="?page={{ courses.paginator.num_pages }}">last &raquo;</a> {% endif %} </span> </div> </div> {% for faculty in faculties %} <div id="fac_{{ faculty.pk }}_tab" style="display:none;"> <h3> {{ faculty.name }} Courses</h3> <ul> {% … -

As per the Django-Compressor docs: If you use any variables inside the {% compress %} blocks, make sure to list all values you require in COMPRESS_OFFLINE_CONTEXT How would I go about adding the Page instance to the context in my settings? I thought of something like (pseudo-code): COMPRESS_OFFLINE_CONTEXT = { 'page': request.get('page') }
