Django - Cant activate users after registration
I'm trying to activate users after their registration. First, user submits a form with his personnal information, then he receives a confirmation link redirecting to a form to define his password. After registering this password, I'm trying to activate and authenticate the user. However is_active doesn't stay to True when I set it programmatically but it works when I do it in the admin interface. I'm really confused and have no idea what to look for. Below are my user models and the concerned view. Thanks in advance for any help. Models class User (AbstractUser): # some fields validation_token = models.CharField (max_length=32, null=True, blank=True) def __str__(self): return self.username class IndividualUser (User): # some other fields The activation view form = PasswordForm(request.POST) if form.cleaned_data.get('password1') == form.cleaned_data.get('password2'): user.set_password(form.cleaned_data.get('password1')) user.is_active = True user.save() user = authenticate(username=user.username, password=form.cleaned_data.get('password1')) login(request, user) -

Django trouble creating function to delete all items in sessions / cart
I'm trying to create a function to empty all of the items from my cart in sessions. I have a perfectly good function that removes individual item, but can't get it to work for all. Can you let me know what I'm doing wrong? Thanks! I've tried to create the following function: cart.py class Cart(object): ... def clear(self): self.session.cart[settings.CART_SESSION_KEY] = {} self.session.modified = True Called it in my url/views/template like: urls.py path('cart/clear/', Buylist_views.clear, name= 'empty_cart'), views.py def clear(request): cart = Cart(request) cart.clear() return redirect('cart') template ... <button type="submit" formaction="{% url 'empty_cart' %}"> Empty Cart </button> </form> I've also tried the following function: def empty(self): for each in self.cart: del each self.save() Your insight would be much appreciated! -
Django scrf verification failed
I'm currently trying to adjust my django server with gunicorn and gninx. I met several issues when I tried to upload files : with time-out which I solved by adjusting gninx and gunicorn parameters. SOLVED with file's max_size which I solved by adjusting gninx parameters. SOLVED with "scrf verification failed" : I added the following settings : 'django.middleware.csrf.CsrfViewMiddleware' I added the crsf_token in each of my forms Upload works for little files but I would like to upload file with a max_size of 70Go. I tried to upload 10Go files, it works. I tried to upload 20Go files, and "scrf verification failed" happened. So I have several questions : Where does this issue could come from? Given that it takes a lot of time to transfer files, could the srcf_token be "outdated"? Do you have some ideas/pointers in order to solve this issue? -

Django & Js : use cleaned_data instead of request.POST on simple HTML inputs
i've created a form in forms.py , and after submiting the form, the values are inserted in my database smoothly, using form.cleaned_data. my template has a button (called : "ajouter une ligne") that adds a new line (the line contains a form similar to the original one). this action (of adding line) is coded by Js. my problem is ,when i want to submit the final form that contains the original line and the second . it only submits the first one, because the first ligne is created on forms.py so on submition it's submited with clean_data . However the second line is created on the template using js directly so form.cleaned_data doesn't work on it. here is my template original row : <form action="/veentes" method="POST" enctype="multipart/form-data">{% csrf_token %}{{ form.non_field_errors }} <table style ="border-collapse: separate;border-spacing: 15px;" id="div1"> <tr><td width="5%">N P</td><td width="25%">Désignation</td><td width="8%">Date de Facture</td><td width="10%">Montant HT</td><td width="10%">TVA</td><td width="10%">Montant TTC</td></tr> <tr style="border:1px solid black;" > <td><div class="col-xs-1"><b><p name="np1">1</p></b></div></td> <td> {% render_field form.designation1 class="form-control" id="inlineFormInputName" placeholder="désignation" name="designation1" %}{{form.degn.errors}} </td> <td>{% render_field form.datefacture1 class="form-control" id="inlineFormInputName" placeholder="Date de Facture" name="datefacture1" %}{{form.dateFac.errors}} </td> <td> {% render_field form.mht1 class="form-control" id="inlineFormInputName" placeholder="Montant HT" name="mht1" %}{{form.mht.errors}} </td> <td> {% render_field form.mtva1 class="form-control" id="inlineFormInputName" placeholder="TVA" name="mtva1" %}{{form.mtva.errors}} </td> <td>{% … -
Django ForeignKey Validation For Multiple Databases

Problem: I have a model class called 'Accomm' in my Django project where I have a number of objects stored.

Best Practice - Router: with Django Rest Framework for Many-to-Many relationship
I am developing a Restfull API with Django and Django Rest-Framework and DRF. I have the following models. class Account(models.Model): [...] class Course(models.Model): sudents = models.ManyToManyField(Student, through='StudentCourse', blank=True) class StudentCourse(models.Model): student = models.ForeignKey(Account) course = models.ForeignKey(Course) As you can see, the course can be created without students. But Students should be able to subscribe the course later. api/accounts/<username>/courses #-> return list of courses the student has subscribed api/courses/<id>/accounts #-> return a list of all students in the course api/courses/<id>/accounts/<username> #-> create StudentCourse relationship How do I have to implement the views, what's the best practice to create the relationship (focus on the routes)? Should there be an extra API endpoint for the StudentCourse-Model or is that okay? -
How to correctly consume external API pagination?
I wonder what is the correct way to consume external API pagination. I have a "Service A" API which returns paginated list of objects. I have a "Service B" which gets data from "Service A" API. Now i would like to implement pagination in "Service B" but i have no idea how should it be done. Let's assume that "Service A" returns 10 objects per page and "Service B" also should display 10 objects per page. Thank you -
Django query selecting values and objects
I have a problem with the queries when selecting values and objects. Here is a sample structure: class Property(models.Model): name = models.CharField(max_length=70, blank=True, verbose_name="Property Name") type = models.CharField(max_length=10) class Agreement(models.Model): property = models.ForeignKey(Property, on_delete=models.CASCADE, related_name="prop") renter = models.ForeignKey(User, verbose_name="Kiracı", related_name = "renter01") Here is the first filter. qs1 = Agreement.objects.all() This one returns property and renter as objects. So I can refer the object details such as for q in qs: print(q.renter.firstname) Here is the second filter. When I need only some fields I use this filter: qs2 = Agreement.objects.all().values('renter',...) In that case the query returns the pk value of the renter user; and I cannot use it as object. Is there a way that I can select certain columns and keep the objects in it as objects? -

cPickle datetime ImportError
I am having an ImportError when loading a pickle file, but the error only happens in one particular file, and not in other(s). So file1.py consists of a handful of function definitions to create a particular model given a pickle file with data. The other file, test.py, uses the functions in the previous file to create instances given different pickle files so those objects can be tested. I had never had any problem with cPickle in the test file up until now and I have no idea why this started happening. My test file just looks like this: import os from django.test import TestCase from file1 import import_object class PickleTest(TestCase): fixtures = [...] @classmethod def PickleTest(cls): super(DebugTest, cls).setUpClass() # instantiate an object for each pickle in the pickles directory path = 'pickles' for f in os.listdir(pickles_path): if f.endswith('.p'): import_object('{}/{}'.format(path, f)) def test(self): self.assertTrue(1 + 1, 2) The error happens when calling import_object.

I have a javascript function for plotting a graph on the basis of an array. The array has to be passed from the views.py in django. I am using jinja logic for passing the array from django. This is my views.py: def index(request): #style.use('ggplot') auth_tok = 'ozznMBmrYaK5QcBngxUq' df = quandl.get('WIKI/GOOGL',authtoken=auth_tok) df = df[['Adj. Open','Adj. High','Adj. Low','Adj. Close','Adj. Volume',]] df['HL_PCT'] = (df['Adj. High'] - df['Adj. Close']) / df['Adj. Close'] * 100.0 df['PCT_change'] = (df['Adj. Close'] - df['Adj. Open']) / df['Adj. Open'] * 100.0 df = df[['Adj. Close','HL_PCT','PCT_change','Adj. Volume']] forecast_col = 'Adj. Close' df.fillna(-99999,inplace=True) forecast_out = int(math.ceil(0.01*len(df))) df['label'] = df[forecast_col].shift(-forecast_out) x = np.array(df.drop(['label'],1)) x = preprocessing.scale(x) x = x[:-forecast_out] x_lately = x[-forecast_out:] df.dropna(inplace = True) y = np.array(df['label']) y = np.array(df['label']) X_train , X_test , y_train , y_test = cross_validation.train_test_split(x,y,test_size=0.2) clf = LinearRegression(n_jobs = -1) clf.fit(X_train , y_train) accuracy = clf.score(X_test,y_test) forecast_set = clf.predict(x_lately) print(forecast_set, accuracy , forecast_out) df['Forecast'] = np.nan last_date = df.iloc[-1].name last_unix = last_date.timestamp() one_day = 86400 next_unix = last_unix + one_day for i in forecast_set: next_date = datetime.datetime.fromtimestamp(next_unix) next_unix += one_day df.loc[next_date] = [np.nan for _ in range(len(df.columns) - 1)] +[i] df = df.values df.tolist() x1 = [2005,2007,2009,2011,2013,20150] y1= df[0] print(y1) return render(request, 'visit/index.html', {'onY' : y1 , …
