Django Image upload issue Cloundinary
i'm learning Django at present and just about getting to the deployment stage at hit a problem serving static/media with Cloudinary, following guides how to do this, it seems straight forward enough. I've checked the Cloudinary support but I can't find anything to help, just wondering if anyone has any input. The problem I have is that I am using Exiffield (to get image info) and ImageSpecField from ImageKit to resize the images for thumbnails and I think this is giving me problems with Cloudinary. Firstly I can't upload images from Admin, I get a Exception Value:Empty file error. Secondly I get 400 Client Error: Bad Request for url: https://res.cloudinary.com/ **path to file*** when trying to open my site (which is being served locally and in development This is using ImageField as upload. I would change it to CloudinaryField but my model heavily relies on ExifField which wont read from it. Model below. image = models.ImageField(upload_to='images') mid_thumbnail = ImageSpecField(source='image', processors=[ResizeToFit(220, 150)], format='JPEG', options={'quality': 100}) gallery_thumbnail = ImageSpecField(source='image', processors=[ResizeToFit(300, 250)], format='JPEG', options={'quality': 100}) gallery_detail = ImageSpecField(source='image', processors=[ResizeToFit(1000, 850)], format='JPEG', options={'quality': 100}) title = models.CharField(max_length=100) albums = models.ManyToManyField(Album, blank=True, related_name='photos') feature_image = models.BooleanField(default=False) description = models.CharField(editable=False, max_length=150, blank=True) posts = models.ManyToManyField(Post, blank=True, … -
Django - Paypal Cancel Suscription
I recently used the django-paypal library in my project. All is working fine, the only problem I'm facing is that I don't find the way to implement a cancel button (to cancel a suscription) or an upgrade button (to change the suscription plan). There is no mention of those buttons in the documentation, so I guess I'm asking this question here to confirm that it can't be achieved with the django-paypal library -

Make select field toggle another field using Django Forms WITHOUT jQuery
How can I create a toggling behavior using Django form fields such as shown in the gif purely using Django? In the example below the user is prompted to choose only a Division or Center, if the division is chosen, center will automatically be prompted to None and vice versa. In order to create the effect shown, I am using jQuery and some beginner Django code: <div class="col-md-5"> <label>Division </label> <select id="division" name="division" class="form-control select2"> {%for division, name in divisions%} <option value="{{ division }}">{{ name }}</option> {% endfor %} </select> </div> <div class="col"> <h3><strong>OR</strong></h3> </div> <div class="col-md-5"> <label>Center</label> <select id="center" name="center" class="form-control select2"> {%for center, name in centers%} <option value="{{ center }}">{{ name }}</option> {% endfor %} </select> </div> $(document).ready(function () { // Set option selected onchange $("#center").change(function () { // Set selected if ($("#division").val() != "None" && $("#center").val() != "None") { $("#division").val("None"); $("#division").select2().trigger("change"); } return; }); $("#division").change(function () { // Set selected if ($("#division").val() != "None" && $("#center").val() != "None") { $("#center").val("None"); $("#center").select2().trigger("change"); } return; }); }); However the rest of my fields are declared using django forms: class NewTitlesForm07(forms.Form): def __init__(self, *args, **kwargs): super(NewTitlesForm07, self).__init__(*args, **kwargs) self.fields['start_month'] = forms.ChoiceField(choices=MONTH_CHOICES, widget=forms.Select(attrs={'class': 'select2 form-control'})) self.fields['start_year'] = forms.ChoiceField(choices=YEAR_CHOICES_07, widget=forms.Select(attrs={'class': 'select2 form-control'})) … -
Set value of GeoDjango map widget in change form based on other field using jQuery
I'm working on a project that uses GeoDjango and django-cities. I have one model: class Site(models.Model): name = models.CharField(max_length=60) assigned_to = models.ForeignKey( to=User, on_delete=models.PROTECT, null=True, blank=True ) country = models.ForeignKey( to=Country, on_delete=models.PROTECT, null=True, blank=True ) # Region selection should be limited to country region = ChainedForeignKey( to=Region, chained_field="country", chained_model_field="country", on_delete=models.PROTECT, null=True, blank=True, ) # City selection should be limited to region city = ChainedForeignKey( to=City, chained_field="region", chained_model_field="region", on_delete=models.PROTECT, null=True, blank=True, ) location = PointField(null=True, blank=True) This is the planned workflow: User sets the country of the site User sets the region of the site (selection is limited by country) User sets the city of the site (selection is limited by region) When the city changes, the point on the map widget for the location field jumps to the location of the city The user then fine-tunes the location manually and saves In order to achieve this, I have added this js file using the Media class in SiteAdmin: $(document).ready(function() { $("select[name='city']").change(function(e) { const cityId = e.target.value geodjango_location.clearFeatures() // Get the location of the selected city $.ajax({ "type" : "GET", "url" : `/sites/admin/city-location/${cityId}/`, "dataType" : "json", "cache" : false, "success" : function(json) { // Use the city's location as the value … -
Processing a Django form
I have a problem using Django forms while learning Django and adapting code from a variety of online courses and examples. As a result, the code may be “messy” – but if I can get it to work the way I need, I can improve my coding style later. I wish to display a template that contains a form. Some of the data displayed in the page rendered in the template is read from one table/model, polls_CC_Questions, and I wish to write data input in the page into a related table, polls_CC_Resp_NoFK. The models used are: class CC_Questions(models.Model): q_text = models.CharField('Question text', max_length=200) C1_Type = models.CharField('Choice 1 Type', max_length=2) Choice1_text = models.CharField('Choice 1 text', max_length=100) C2_Type = models.CharField('Choice 2 Type', max_length=2) Choice2_text = models.CharField('Choice 2 text', max_length=100) # def __str__(self): return self.q_text[:20] class CC_Resp_NoFK(models.Model): Person_ID = models.IntegerField() Test_date = models.DateTimeField('date test taken') Q_ID = models.IntegerField() Response_value = models.IntegerField(default=0, validators=[MaxValueValidator(100), MinValueValidator(-100)]) # def __str__(self): return self.Person_ID Now I can display the template containing valid data when I enter the url: http://localhost:8000/polls/p2vote/4/ This is processed in urls.py app_name = 'polls' urlpatterns = [ ….. …… # ex: /polls/p2vote/<q_id> path('p2vote/<int:q_id>/', p2_views.p2vote, name='p2vote'), …..

Django static file images not displayed on IBM Cloud Foundry
I've read some other threads, googled, and tried reading docs but can't find what I'm looking for. I am new to playing with Django, fyi. This same code runs alright on my local and also on pythonanywhere.com My web app displays a list of 'interests', 'images', and a 'urls'. The 'image' is actually a path to the local image file. The app deploys fine to IBM Cloud Foundry and works, except that the images in static files do not display only the broken image icon displays. When I deploy, I see in the logs the message "153 static files copied to '/tmp/app/static'" which leads me to believe the collectstatic ran without issue. from models.py: class Interest(models.Model): interest = models.CharField(max_length=100) **image = models.ImageField(upload_to='interest/images')** url = models.URLField(blank=True) def __str__(self): return self.interest From the html template: {% extends 'portfolio/base.html' %} {% block about-class %} about-color-class {% endblock %} {% block content %} {% load static %} <!-- Interests --> <section class="interests"> <div class="container"> <div class="row"> <h1>Some of my interests...</h1> </div> <div class="row-images"> {% for interest in interests %} <div class="col-lg-1 col-md-1 col-xs-1"> <a href="{{ interest.url }}"><**img src="{{ interest.image.url }}" alt=""**></a> </div> {% endfor %} </div> </div> </section> <!-- Interests End --> From settings.py: … -

Python/Django json.loads() error when loading JSON File
In my Django project I have the following directory structure: project/build/contracts/MyFile.json And I am writing code in the following directory project/homeapp/views.py In my views.py I have the following code: with open("../build/contracts/MyFile.json", "r") as f: data = json.loads(f.read()) abi = data["abi"] When I try to python manage.py runserver I get the following error: The strange part is that I couldn't figure out what was wrong so I made a viewstest.py and placed the exact same code in it. When I run it with python .\viewstest.py and print the JSON to console, it works perfectly fine. I even tried importing the abi variable from viewstest.py to views.py but got the same error. So I assume that it is an error relating to Django, but I can't seem to figure it out. Thanks! -

cudart64_110.dll Loading Multiple Times
I am working on a Django Web Application that uses Tensorflow for some image processing on the backend. As such I have installed CUDA and when I run the web application initially it loads the cudart64_110.dll and provides the following message, which is fine. tensorflow/stream_executor/platform/default/dso_loader.cc:53] Successfully opened dynamic library cudart64_110.dll Within my application I have a Pool.map function for multiprocessing (which is not related to the tensorflow processing, but only to generate some jpegs) as below: pool = Pool(4) pool.map(func_star, zip(index_arr, nrrd_path_arr, user_path_arr, g_img_arr, g_contour_arr, itertools.repeat(results))) The issue I am facing is that whenever this function runs, it also loads the cudart64_110.dll corresponding to the number of processes that I specify in the Pool(x). In the above instance it loads the .dll 4 times as below: This leads to memory issues and crashes the app. I am not entirely sure why this is happening or how can I approach about solving this issue. Any help on how can I avoid this issue would be really appreciated! -
