blank page in pagination Django 3.1
I implemented the Django pagination to slice the results of the search on my site. # views.py def search(request): # Keywords if 'keywords' in request.GET: keywords = request.GET['keywords'] if keywords: title_list_control_valve = queryset_list.filter(title__icontains=keywords).order_by('title') description_list_control_valve = queryset_list.filter(description__icontains=keywords).order_by('description').distinct('description') result_list_control_valves = list(chain(title_list_control_valve, description_list_control_valve)) result_list_control_valves_2 = list(dict.fromkeys(result_list_control_valves)) paginator = Paginator(result_list_control_valves_2, 1) page = request.GET.get('page') paged_queries = paginator.get_page(page) context = { 'queries': paged_queries, } return render(request, 'pages/search.html', context) else: return render(request, 'pages/search.html') else: return render(request, 'pages/search.html') the URL of the site when showing search results is : http://localhost:8000/pages/search/?keywords=something It works perfectly fine on the first page only.

Django on Heroku - missing staticfiles manifest.json file
I am trying to start Django on Heroku. I looked around Stack Overflow, I tried different things, but I cannot figure it out. It looks similar to all the questions related to staticfiles problem on Django, unfortunately I don't know where the problem is. My project runs just fine with DEBUG = True, but when I change it to False, I get following traceback: 2020-11-09T13:13:42.801384+00:00 app[web.1]: Missing staticfiles manifest entry for 'order/css/open-iconic-bootstrap.min.css' It happens on all of my apps that require staticfiles. I tried to find manifest.json, but it does not exist. So I think this is the issue. Here are my relevant settings: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', #more ... ] STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static') ] STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATIC_URL = '/static/' STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage' django_heroku.settings(locals()) Thanks for looking into this! -

Creating a Job using Django to fetch data from API
I am doing a project using Django that will consume an external API. However, in this project I will need to set up the times that django will consume this Third API. So basically, I will need to creat a job to fetch this data. Do you guys have any public github or a manual that I can use as an example? I never did this before and it is so hard to find a tutorial about it or something like that. -

AttributeError: Got AttributeError when attempting to get a value for field `images` on serializer `ArticleViewSerializer
What i am trying to do is create a serializer to post multiple images for an article as ArrayField(ImageField()) does not work. I have checked if there is any typo or so but it seems like there is no typo.Serializers work fine separately,only i get this problem where i try to combine them.

How can I get custom form field value from within Django Admin's response_change?
I've added a custom functionality to a model by overriding change_form.html. Basically, I'm letting users change the objects of a model if these changes were approaved by the admin. I added two buttons, named accept-suggestion and decline-suggestion and I intend to handle the custom functionality through response_change method: def response_change(self, request, obj): if "decline-suggestion" in request.POST: # do stuff... if "accept-suggestion" in request.POST: # do stuff... Both buttons will send an e-mail to the user saying if the suggestion was declined or approaved. So far so good. The problem is that I want to add the possibility to the admin write a brief justification explaininig why the suggestion was declined. So I changed change_form.html again. <div class="submit-row"> <div class="float-left"> <a class="decline-button-outlined accordion" type="button" href="#">DECLINE SUGGESTION</a> </div> <div class="float-right"> <input class="accept-button" type="submit" name="accept-suggestion" value="ACEITAR SUGESTÃO"> </div> </div> <div class="additional-infos"> <fieldset class="module aligned"> <div class="form-row"> <label for="decline-reasons">Reasons for rejection:</label> <textarea placeholder="If you find necessary, provide information on the reasons that led to the rejection of the suggestion" id="decline-reasons" class="vLargeTextField" rows="5"></textarea> </div> <div class="submit-row"> <div class="float-right"> <input class="decline-button" type="submit" name="decline-suggestion" value="DECLINE"> </div> </div> </fieldset> </div> This is the best approach? If yes, how can I get the value of the <textarea> above from … -
How to solve CSRF "Forbidden Cookie not set" error in Django?
I am using Angular 8 as frontend and Django 1.11.18 as backend. I am running my Angular project on https://127.0.0.1:4200 through command ng server --ssl true and Django API's are deployed on a separate redhat server and can be accessed through https://192.xxx.x.xx:7002/ My Login is a GET Request that returns success response with csrf token in header but cookies are not received on the browser at that time and when I call my POST request this cause "Forbidden" error due to CSRF Token.

One thing more I would like to mention is that When I deploy the Angular project on the same server on which Django API's are applied then application works fine. -

Django __exact queryset filter - case sensitivity not working as expected
I am trying to filter a Django queryset where the case should be sensitive, although I am not getting the results I expect from the "__exact" filter, which I believe to be case-sensitive: https://docs.djangoproject.com/en/3.0/ref/models/querysets/ My code looks like this: lower_case_test = MyObject.objects.filter(name_exact="d") for item in lower_case_test: print("item.name: ", item.name) I have 2 in the "MyObject" model, one with name "d" and one with name "D".

Accessing django model attribute passed as a parameter
I'm using django with a legacy database where I can not change the original table columns. I have similar models which have slightly varying field names. The following model is an example. class EURegister(models.Model): record_id = models.AutoField(primary_key=True) reg_no = models.CharField(max_length=45, blank=True, null=True) company_name = models.CharField(max_length=300, blank=True, null=True) In some models, reg_no is a different name such as registration_id. Hence, I have to access the model attribute passed as an argument. But I can not use it since the model doesn't allow to use attributes as they were dict keys. It gives the following error. TypeError: 'EURegister' object is not subscriptable -

Django dynamic form subclass list
I'm trying to understand how can I define model as a class containing 2 integers and 1 charfield and then make it a part of another model. Example of data I need I guess in object oriented programming I should define model class like this: class Component(models.Model): pipe_type = models.CharField(max_length=200) length = models.IntegerField() amount = models.IntegerField() And then I don't know how can I use it with django models, it should be something like this: class Item(models.Model): name = models.CharField() components_needed = ? LIST OF Component class ? Also, since components needed size will wary for objects, it should be possible to extend it's size with button on a page, for example there could be 3 input fields and next to them would be "+" and "-" button to add/remove another set of 3 input fields I spent entire day looking for solution, but at this point I'm not sure if django can handle this. I'm new to python and django, so there are many things I do not understand. I will be grateful for any kind of help -

Building a Fantasy Football App. If player name is not in JSON data file, set score to zero. Sounds simple, but how do I get it to work?
I'm building a very simple fantasy football web-app using django for a course. One bug I discovered recently was that if a player isn't present in the JSON data that I'm pulling from an api, then it throws an error stating that the local variable for that player's score is being referenced before being assigned. Makes sense given that there is no actual data for that player. So, to fix this, I figured all I needed to do is add an elif (or else) statement to my logic to set that player's score to zero. Here's my code for this so far. for score in scores: if score['player_name'] in QBname: QBscore = float(score['points']) totalpoints.append(QBscore) I'm looping through a list called "scores" where I have the player scores coming in from an api call, then I'm comparing the player's name, which is stored in a variable called "QBname", to score['player_name]. Obviously, if score['player_name'] is a match and is in "QBname", I'm then appending that player's score to the variable "totalpoints." Now, to "fix" the problem, and assign a score of 0 to an absent player, I thought I would need something like this... if score['player_name'] in QBname: QBscore = float(score['points']) totalpoints.append(QBscore) … -
Error in passing filtered data to template. Reverse not found. 1 pattern(s) tried. What query should be used to avoid this error?
I am trying to create a dynamic url that displays all the sub-courses in course. To do this I am passing the course name through the url and filtering the sub-courses to only send the ones for this course. However I cannot seem to find the correct query to filter and pass the data. I attempted to follow the official Django documentation and search stack to find an answer but found nothing. My experimentation has also gotten me no results. the view is def subcourse(request, course): if request.method == 'GET': course = Course.objects.get(slug=course) subcourses = Subcourse.objects.all().filter(course=course) context = {'subcourses': subcourses} return render(request, 'subcourse.html', context) and my models are: class Course(models.Model): slug = models.SlugField() title = models.CharField(max_length=120) thumbnail = models.ImageField( upload_to='images/courses', null=True, blank=True ) position = models.IntegerField() def __str__(self): return self.title class Subcourse(models.Model): slug = models.SlugField() title = models.CharField(max_length=120) course = models.ForeignKey(Course, on_delete=models.SET_NULL, null=True) thumbnail = models.ImageField( upload_to='images/subcourses', null=True, blank=True) position = models.IntegerField() def __str__(self): return self.title and the current error message is Reverse for 'subcourse' with arguments '('',)' not found. 1 pattern(s) tried: ['training/(?P<course>[-a-zA-Z0-9_]+)$'] I have read through the documentation regarding queries and filters but cannot seem to find my error.
