Deleting a value from a field of model in django

Django: Create a form for another other user existing in DB. ('Users' object has no attribute 'get')

Ajax success function not working: Django JSONResponse not sending
In the code below, I am using onclick (I know it may not be the best practice but for my particular situation I think it works best) to activate an ajax call to dynamically update the content on my Django template. As of now, the data is going to the back-end, and the Comment object is being created. However, when returning a JSONResponse, the template is not using the data from this JSONResponse to update the page in any way. I have tried testing with alerts but to no avail. I am new to JS so I would love a little help! Thank you very much.

Django Monolithic vs Microservices
I always had this doubt and want to clear it up. Django architecture is somewhat similar to microservices architecture in the sense all the apps in a Django project are isolated which is the same case in Microservices architecture. If one app fails, it doesnt affect other apps. So is it fair considering a Monolithic Django App to be a Microservices architecture? -
Custom Registration form in django shows "This field is required" even when it's filled

How to avoid 2 equal loopings | Django
I got this code: i = 1 for item in cart: data_ps[f"itemId{i}"] = item data_ps[f"itemDescription{i}"] = item.category.name data_ps[f"itemAmount{i}"] = item.sell_price data_ps[f"itemQuantity{i}"] = '1' i += 1 total_value = format(((shipping_price + cart_price) / installment), '.2f') data_ps['installmentValue'] = total_value response = requests.post('https://ws.sandbox.pagseguro.uol.com.br/v2/transactions', headers=headers, params=params, data=data_ps) if response.status_code == 200: for item in cart: Sell.objects.create(item=item, date=timezone.now(), discount=Decimal(0.00), total_paid=cart.get_total_price(), buyer=request.user, ) As you can see, there are 2 for item in cart loop. After the first one, I need to get a request.post and then check if the status_code is equal 200. If so, the code gerenates another for item in cart loop. I was wondering if there is a way to avoid the second looping adding all this information inside the first one, because it just update a record in my database ('Sell.objects.create'). Any idea?

How to load spesific data with ajax in django?
I was want to learn "how ajax working on django ?" so I found this project from web and started the working on this https://www.sourcecodester.com/tutorials/python/11762/python-django-simple-crud-ajax.html I got something from that project but reverse engineering is did not work :/ When I run the project of this link and create a person was everything ok, like if I do not write the firstname as required input ajax gives me an eror. My button is too should working like this. But later when I wrote my own code block and pressed the (mydata) button I did not get an eror or something so I think ajax did not work and I do not know why Script.js This script is in the document.ready function $('#mydata').on('click', function(){ $firstname = $('#firstname').val(); if($firstname == ""){ alert("Please complete the required field"); }else{ $.ajax({ url: 'mydata', type: 'POST', data: { firstname: $firstname, csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val() }, success: function(response){ console.log('working!') $('#result').html(response); } }); } }); Views.py def mydata(request): firstname = request.GET.get('firstname') members = Member.objects.filter(firstname=firstname) context = {'member': members} return render(request, 'crud/index.html', context) index.html <form class="form-inline"> {% csrf_token %} <div class="form-group"> <label>Firstname</label> <input type="text" id="firstname" class="form-control" style="width:30%;" required="required"/> <label>Lastname</label> <input type="text" id="lastname" class="form-control" style="width:30%;" required="required"/> <button type="button" id="create" class="btn btn-sm btn-primary">Create</button> … -
Record user IP address in Django During Development, not 127.0.0.1
Using Django 3.0.8, I am trying to record a user's IP address during development to ensure my database isn't spammed by multiple submissions from the same IP Address. I am currently using Django's in-built request.META.get("REMOTE_ADDR") as per the Django docs, but this only returns the 127.0.0.1 when I print out to the terminal. Is there a more robust way to obtain the IPv4/IPv6 address during development? -
Django model class relationships
I'm trying to map out the relationship between my models and before I spend to much time creating the form to create the objects on the client side I want to check it's the most efficient way of doing so. I am creating form that allows me to create a Workout. Each Workout consists of multiple exercises. However, I want the ability to be able to group exercises into Sets (Supersets). So you can either perform one exercise on its own OR 2 or 3 exercises back to the group. e.g. Workout Exercise: 1 Sets 4 Reps 12 Exercise: 2 Sets 3 Reps 10 Superset: 3 Exercise a Exercise b Sets 4 Reps 3 Exercise: 4 Sets 4 Reps 3 I current Have a Workout class with a ManyToMany to my Set class, which then has a ManyToMany to the Exercise Class. Each exercise needs to have sets and reps etc. However, something doesn't feel right about creating a 'Set' object, then assigning exercises to it. Especially when creating a single exercise object. My models currently look like the following: class Workout(models.Model): title = models.CharField(max_length=50) account = models.ForeignKey("customer.Account", on_delete=models.PROTECT) date_created = models.DateField(_('Creation date'), auto_now_add=True) set_of_exercises = models.ManyToManyField("gym.Set", blank=True) def __str__(self): … -

Django: is there a simple way to store choices on the database
Seems basic as a need but I cannot find a way to store Django choices (the actual list of tuples) in database. My use case it that I have a Django app with multiple models and fields with choices. At the app level, I can always get the mapping from field value using get_foo_display or accessing the tuple, but it seems that it’s not actually stored on the DB. Considering that I connect to the DB directly for some stats and BI, I’m missing the mapping for my analysis and reports. Unless there’s some technique to do so, I guess I’ll create a « supporting » model to store the mappings. I would really appreciate your inputs/thoughts. Thank you. -
django_rest_framework: how to write an update_partial() method in a nested serializer to add or remove an object
I've been reading all over the internet and cannot find the answer to this question. below I have two datasets, dataset A and dataset B.

Can't preview the clicked button value
I am trying to preview the values of a bunch of buttons whenever they clicked. I already asked a question here and solved a part of my problem. however there is a small bug which stopped me for long time. This is the mytemplate.html(which almost does what I expect): <div id="preview-items"> </div> <script> $("#id_country").change(function () { var countryId = $(this).val(); // get the selected country ID from the HTML input success: function (data) { $('#preview-items').html(''); for (var i in data.tags) { $('#preview-items').append(` <label class="btn btn-primary mr-1"> <input type="checkbox" id="checklist" value="` + data.tags[i][0] + `"> <span> ` + data.tags[i][1] + ` </span> </label><br />` ); } } }); </script> And this is the script to preview the value of clicked buttons <script> $(function() { $(":checkbox").change(function() { var arr = $(":checkbox:checked").map(function() { return $(this).next().html(); }).get(); $("#preview-items").html(arr.join(', ')); }); }); </script> When I replace the first script with a simple button like below, it works perfectly: <div> <label class="btn btn-primary mr-1"> <input type="checkbox" id="Checklist" value="{{ item.0 }}"> <span> ITEM </span> </label> </div> Please help, I am spending too much to find just a tiny bug. -
Are there alternate methods for Django User authentication?
Can I authenticate users using a 'secret' and a registered IP? For each user I want to have a provide a 'secret' (a simpler password) and registered IPs (their home and work IPs). Then I want to allow access to certain pages only when Logged in using this method? Is this feasible? Any suggestion on how to achieve this is welcome. Bit of background: the Django website allows users to connect to a CRM service that uses OAuth. Users manage multiple CRMs (belonging to multiple clients). They separate clients by creating a separate chrome profile to each client. Right now they have to login to the Django website in each profile to connect to the CRM OAuth. If I can identify users using an IP and secret, they don't need to login in each of their client chrome profiles, so makes the process easier and convenient. Besides they do not need access to the whole site while logged in using the secret, on the page that kicks off the OAuth process and the redirect page. -

Here's the code I've tried so far: -Form Code: class ArticleForm extends React.Component { this.props.onSendNewArticle( fieldsValue.upload.fileList[0]); render() { <Form.Item name="upload" label="Image" onPreview={this.handlePreview}> <Upload accept=".jpeg, .png" beforeUpload={() => false}> <Button> <UploadOutlined /> Choisir une image </Button> </Upload> </Form.Item> } const mapStateToProps = (state) => { return { loading_add_article: state.add_article.loading_add_article, error_add_article: state.add_article.error_add_article, }; }; const mapDispatchToProps = (dispatch) => { return { onSendNewArticle: (image) => dispatch(actions.articleAdded(image)), }; }; export default connect(mapStateToProps, mapDispatchToProps)(CourseForm); -Here's my view.py class ArticleCreateView(APIView): parser_classes = (MultiPartParser, FormParser) def post(self, request, *args, **kwargs): article_serializer = ArticleSerializer(data=request.data) if article_serializer.is_valid(): article_serializer.save() return Response(article_serializer.data, status=status.HTTP_201_CREATED) else: print('error', article_serializer.errors) return Response(article_serializer.errors, status=status.HTTP_400_BAD_REQUEST) -Here's my store/actions/addArticle.js: export const articleAdded = ( image) => { return (dispatch) => { dispatch(articleDispached); axios .post("http://localhost:8000/api/create/", { img: image }) .then((res) => { const course = res.data; dispatch(articleAddSucess(course)); }) .catch((err) => { dispatch(articleAddFailed(err)); }); }; }; Here's the error that I get: POST http://localhost:8000/api/create/ 415 (Unsupported Media Type) -
APScheduler for creating and loading model
I have a recommendation system project made on python/django. Now I have one Main_Trainer file that trains a recommendation model and I have one Main_Recommender file that gives a recommendation. In my apps.py, I am checking whether the recommendation model is present as a pickle file or not. If present, I am loading the pickle file in a variable there so that it can be used by Main_Recommender file for giving recommendations and I don't have to load model again and again and hence performance is enhanced. If recommendation model is not present, before initializing variable I'm calling the main_trainer function in Main_Trainer file and then loading the pickle file in a variable. Now I want to place a scheduler here such that my trainer runs everyday at 11pm so that my model pickle file is replaced and then load the model pickle file again in the variable. By the time model trainer is running at 11pm, I want my project to use existing file for the recommendation and after the model is created, suppose at 11.30pm, I want my model variable to get refreshed. How can we achieve this scenario? -
Validation not ocurring for custom field type in Django
I'm attempting to make a custom type in Django: from django.db.models import DecimalField from django.core import validators from django.utils.functional import cached_property class MinOneHundredDecimalField(DecimalField): @cached_property def validators(self): return super().validators + [ validators.MinValueValidator(100, "Minimum value is 100"), ] And I use this in my model: class MyModel(BaseModel): amount = MinOneHundredDecimalField( decimal_places=2, max_digits=6, ) However when testing, I'm able to set amount to a value less than 100: def test_min_val(self): my_model = MyModel(amount=50) my_model.save() self.assertNotEqual(my_model.amount, 50, "Message here") I also tried adding the validator directly in the model, but I get the same result: amount = MinOneHundredDecimalField( decimal_places=2, max_digits=6, validators=[MinValueValidator(100.0, "Minimum value is 0")] ) Any ideas why this validator isn't working? Ty!
