How to graph a matplot linear function in Django?
I am creating a small web with Django and I am looking to graph a linear function with machine learning in it using matplotlib. When I make the code in Spyder the graphic looks like this here However, when using Django and wanting to embed the graph, an error occurs, although this does not happen if I remove a few lines of code. This is the first part of the code: def plot(request): plt.rcParams['figure.figsize'] = (9, 6) plt.style.use('ggplot') data = pd.read_csv("datos.csv") filtered_data = data[(data['Fecha'] <= 30) & (data['Oxxos'] <= 50000)] colores=['orange','blue'] tamanios=[30,60] f1 = filtered_data['Fecha'].values f2 = filtered_data['Oxxos'].values f = plt.figure() asignar=[] for index, row in filtered_data.iterrows(): if(row['Fecha']>7): asignar.append(colores[0]) else: asignar.append(colores[1]) plt.scatter(f1, f2, c=asignar, s=tamanios[0]) dataX =filtered_data[["Fecha"]] X_train = np.array(dataX) y_train = filtered_data['Oxxos'].values regr = linear_model.LinearRegression() regr.fit(X_train, y_train) y_pred = regr.predict(X_train) ## HERE IS WHERE THE CODE BELOW WOULD GO ## buf = io.BytesIO() canvas = FigureCanvasAgg(f) canvas.print_png(buf) response = HttpResponse(buf.getvalue(), content_type='image/png') f.clear() response['Content-Length'] = str(len(response.content)) return response Until then, the graphic looks something like this here. The code that causes problems is the one that goes between the y_pred = regr.predict (X_train) and the buf = io.BytesIO (). The code that goes between these two lines is responsible for … -
Best and fastest method to add only unique records based on certain fields in Django
I have a model with multiple fields where data is text type for the most part. I want to put a validation that from now on if a new record is being added, it should be unique based on 3 fields. Here one of the fields is a one-to-many field as is in another table. I can try fetching all the records and start checking them using for-loop. I tried using annotate but it seems to help if the record is already in the table, but I want to do this validation before adding. I need a fast method for this validation. class Product(models.Model): brand = models.TextField(default='{}', null=True) sub_brand = models.CharField(null=True) . . . class ProductNetWeight(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE, related_name='product_net_weight') net_weight = models.CharField(null=True) -
No effect on global variable
I have a problem with my code. I am creating a small web application, and I want to retrieve a value that has been entered on an html page. Therefore I use the forms. I am recovering my value in message. I imported another python file "thread.py" which contains a reception() function to assign it to a global variable "var_maman" initialized at the beginning to 0. When I run the DJango application and then run my thread.py program (it continuously displays the global variable) and I enter a value on my site, there is no change on the global variable, I don't know what to do anymore. Thank you for your help! view.py from __future__ import unicode_literals from django.shortcuts import render,redirect from django.http import HttpResponse, Http404 import sql import thread from .forms import ContactForm # Create your views here. def RPI(request,rpi_id): if int(rpi_id) > 10: return redirect("/page/accueil/") Pactive = sql.run("Pactive") Preactive = sql.run("Qreactive") Courant = sql.run("I") form = ContactForm(request.POST or None) if form.is_valid(): message = form.cleaned_data['message'] thread.reception(message) print("Le message est : RPI"+rpi_id+","+message) envoi = True return render(request, 'page/RPI.html',locals()) thread.py import sys import time global var_maman def reception(message): global var_maman print("entre dans reception") var_maman = message if __name__ == '__main__': global … -
Filter models on the basis of dictionary key
I am facing a problem while filtering a record from the database. In my database I have records which contain a dictfield. for eg region is a dictionary which contains other dictionaries like region = {'eastus': {'percentage_change': 0}, 'westus': {'percentage_change': 0}} and I want to fetch eastus or westus. I have tried something like this, but I am getting an empty list. MyModel.objects.filter(region__eq='eastus') any suggestions for this problem? -
Django 2.0: How can I get the upload time/duration of a submitted form (with files)?
I have some forms with file fields. I need to know how long it takes to upload the files once I submit the form. I don't need the time for every file, just for the whole form. I'm thinking of getting the upload start and end times, then get the difference between the two. Problem is, I don't know where I should exactly put them. I thought of putting it somewhere at the beginning of the related view functions, but in my tests, they run after the files have been uploaded. I'm also looking at writing a custom Upload Handler (https://docs.djangoproject.com/en/2.2/ref/files/uploads/), but not sure at how to start with it. Since there are only a few forms where I need to get the upload times, I'd prefer to not use any library for this unless it's very necessary. -

Update new field for all users upon migration
I learned Django recently. Now on one of the projects I'm working on, I need to add a new field, is_core_administrator to model UserProfile, which will set the oldest user as a core administrator. I need to update this field for all users with migration. Is there a way to do this? I mean, when I make migrations, is it possible to update this field to true for the oldest user, and false for rest. Finding the oldest user will not be difficult since we already have another field DateJoined. I just want to update the corresponding field on making the migration. -

Design pattern(s) for models based on location and variety of it's properties (child models)?
I'm facing a "writers block" and cannot figure out how to proceed. Everything seems to relate to each other and cannot choose which path to follow. Currently I'm trying to figure out that how should I model entities that are based on location (map) and different properties such as animals on area, possible access restrictions to area on certain dates etc. My current setup has models for Area, Map, Species and Resctrictions. However, I'm not certain that should I separate Map from Area? Or how should I model different Restrcitions types for different such as dates, amounts, allowed vehicles etc.? Do I need BaseResctriction which is inherited by DateResctriction, VehicleRestricion and having some common fields for all restrictions? -
Serializer Error When Using Rest Framework to Serialize Nested Objects from Model

How to embed a linear function with matplotlib in django?
I am developing a Java web application with jsp, servlets, etc. and I need to connect it with a Django html page which will show a linear function for a predictive model. I tried with an example that I found here: https://github.com/hcosta/django-matplotlib-example/blob/master/core/views.py That model works perfectly, however, when I try to show the graph of my linear function something does not work, as you can see here: https://imgur.com/a/dwwIsQ1 Code of the linear function def plot(request): f = plt.figure() plt.rcParams['figure.figsize'] = (9, 6) plt.style.use('ggplot') data = pd.read_csv("datos.csv") print(data.shape) print(data.head()) print(data.describe()) filtered_data = data[(data['Fecha'] <= 30) & (data['Oxxos'] <= 50000)] colores=['orange','blue'] tamanios=[30,60] f1 = filtered_data['Fecha'].values f2 = filtered_data['Oxxos'].values asignar=[] for index, row in filtered_data.iterrows(): if(row['Fecha']>7): asignar.append(colores[0]) else: asignar.append(colores[1]) plt.scatter(f1, f2, c=asignar, s=tamanios[0]) dataX =filtered_data[["Fecha"]] X_train = np.array(dataX) y_train = filtered_data['Oxxos'].values regr = linear_model.LinearRegression() regr.fit(X_train, y_train) y_pred = regr.predict(X_train) def f(x): return regr.coef_*x+2420 x = range(0, 30) plt.plot(x, [f(i) for i in x]) plt.axhline(0, color="black") plt.axvline(0, color="black") plt.xlim(0, 15) plt.ylim(0, 20000) buf = io.BytesIO() canvas = FigureCanvasAgg(f) canvas.print_png(buf) response = HttpResponse(buf.getvalue(), content_type='image/png') f.clear() response['Content-Length'] = str(len(response.content)) return response I hope that the linear function is shown, instead of the icon as if the image of it did not exist. -

Django Formset field label in error messages
Is there a simple way to get the field label in an error message for a Django formset. I am able to do it in a normal form like so: {% if form.errors %} {% for field in form %} {% for error in field.errors %} <div class="alert alert-danger"> <strong>{{ field.label }}: {{ error|escape }}</strong> </div> {% endfor %} {% endfor %} {% for error in form.non_field_errors %} <div class="alert alert-danger"> <strong>{{ error|escape }}</strong> </div> {% endfor %} {% endif %} However, I'd like the same thing for the formset. The closest I've gotten is {% if formset.errors %} {% for dict in formset.errors %} {% for field, error in dict.items %} <div class="alert alert-danger"> <strong>{{ field }}: {{ error|escape }}</strong> </div> {% endfor %} {% endfor %} {% endfor %} {% for error in formset.non_field_errors %} <div class="alert alert-danger"> <strong>{{ error|escape }}</strong> </div> {% endfor %} {% endif %} However, this gives me the field name (e.g. pub_date) instead of the label (e.g. Publication Date). Any help much appreciated! -

How to annotate a queryset with number of days since creation
I'm trying to do some complex ordering based on promotions: an article is promoted every 7th day since creation (the articles expire after 30 days). My approach is to annotate the queryset with the number of days since it was created, but the value of the annotated field (days_since_creation), in my code, is always 0. from datetime import timedelta from django.test import TestCase from django.db.models import ExpressionWrapper, F from django.db.models.fields import IntegerField from django.utils import timezone from .models import Article class ArticleTestCase(TestCase): def test_days_since_creation(self): now = timezone.now() objects_data = [ Article( title='Alrp', creation_date=(now - timedelta(days=5)) # 5 days ago ), Article( title='Bopp', creation_date=(now - timedelta(days=7)) # 7 days ago ), Article( title='Crkp', creation_date=(now - timedelta(days=14)) # 14 days ago ), ] Article.objects.bulk_create(objects_data) article_set = Article.objects\ .annotate( days_since_creation=ExpressionWrapper( now - F('creation_date'), output_field=IntegerField() ) ) for article in article_set: print(article.days_since_creation) # all 3 objects print "0" I expected the value for each object to be 5, 7, 14 repectively. I even tried DurationField but that just printed 0:00:00. After that I would annotate the queryset again with an order field that has the value 0 if the value of days_since_past is in [0, 7, 14, 21, 28,] or 1 otherwise, and then … -
How to properly use aggregate in Django

Django Model Choice Field How to return the primary key of the object instead of the display value

I want the display to the end user to be a string value from my model (which works), but return a the primary key of the Model when the user submits the form (not the display value). I attempted to use the to_field_name="id" on the Django form and it does render the values correctly when the HTML is rendered, but when the user submits the form the value I get back is the display value, not the primary key I am expecting. customer_edit_form.py annual_income = forms.ModelChoiceField(label='Annual income', to_field_name="id", queryset=cust_income_range.objects.all(), empty_label='-- None --') models.py # Annual Income Model class cust_income_range(models.Model): id = models.IntegerField(primary_key=True) range = models.CharField(max_length=50) def __str__(self): return self.range customer_view.py annual_income = form.cleaned_data['annual_income'] -
