Dynamic complex queries with Django
I've these models: class Product(models.Model): description = models.TextField() class Client_Type(models.Model): description = models.TextField() product = models.ManyToMany(Product) class Client(models.Model): description = models.TextField() type = models.ForeignKey(Client_Type) class Order(models.Model): client = models.ForeignKey(Client) date = models.DateTimeField() class Detailed_Order(models.Model): order = models.ForeignKey(Order) product = models.ForeignKey(Product) weight = models.FloatField() Note that I have a many-to-many relationship between Client_Type and Product. I do this because I need to show only a limited list of products to a client, depending of his "type". So when the client orders a product, he will only see the ones selected for his type. Ok, I have no problem doing this. The problem comes with the queries. I need to make a daily report that shows the total amount of Kg buyed by all clients of the respective Client_Type, but only displaying the products selected in the "product" field of Client_Type. Better explained with the following: Client Type: VIP | Client1 | Date | Sum_Product1 (kg) | Sum_Product2 (kg) | Sum_Product3 (kg) | Total_Sum_Client1 (kg) | | Client2 | Date | Sum_Product1 (kg) | Sum_Product2 (kg) | Sum_Product3 (kg) | Total_Sum_Client2 (kg) | The desired result may be getted by the following query, but with the detail that the products displayed in … -
Django doesn't redirect to same or other page after successful HTTP 302 and 200
I've been scratching my head all day long but I don't seem to get it working. My redirects work just fine everywhere else in the app, but don't work when I'm using the forms.py with ModelForm class. So what happens when I hit 'Save' on the form is Django actually does the save successfully and then reports couple of lines in the Debug console as follows, but the browser just stays stalled on the same page without even attempting to go to another page (I've tried redirecting to various views with and without reverse, using HttpResponseRedirect, using redirect, using render_to_response, etc. - just about anything I could find, but Django behaves the same way all the time (see below). It's not a browser caching issue since I've tried redirecting to even the external pages such as google for example, and every time all I'm getting is this: [05/Dec/2017 17:00:41] "GET /music/release/test/edit HTTP/1.1" 200 3310 [05/Dec/2017 17:00:46] "POST /music/release/test/edit HTTP/1.1" 302 0 [05/Dec/2017 17:00:46] "GET /music/releases/ HTTP/1.1" 200 13616 Can anyone please help as I'm really stuck, since all the other redirects are working just fine, it's just the form one that fails for whatever reason. Thx in advance! Here's the … -
Session Hijacking in Django 1.7.7 and python3
I have developed a small application for submitting some data to database server(Oracle 11g). When we are reviewing security of this small application, we observed as follows: 1. We have deployed django with https and all secure configurations like Secure Cookie and Secure Session, No Cache, etc. 2. Using BURP tool for this sample review 3. We have created two different user in this system say Normal User and Admin User 4. Opened 2 browsers(Mozilla and IE 11), On mozilla we login with Admin user and captured session id using burp tool. 5. On second browser we login with Normal user and replaced session id Normal User with Admin User. 6. whoila......On second browser, I got Admin user access by just changing the session id I have used default session backend for this application. I would like to know whether this is flaw in django and how to resolve this issue.. Thanks in advance -
Django Caching on front-end
I was working with 2 applications that are within a DJango project: "customer" and "vendors". Each application has a HTML file named "testindex.html". Whenever I typed: http://myhost/customer/basic_info the correct page would show up If I typed http://myhost/vendors/basic_info the page from http://myhost/customer/basic_info would show up I found out that it was due to caching (since both applications use "testindex.html"). So again, "testindex.html" is caching. How can one get around this problem? TIA Details are listed below. I have the following views defined: urls.py for the project urlpatterns = [ ... snip ... url(r'^customer/', include('libmstr.customer.urls')), url(r'^vendors/', include('libmstr.vendors.urls')), ] views.py for customer from django.shortcuts import render def basic_info(request): return render(request, 'testindex.html', {}) views.py for vendors from django.shortcuts import render def basic_info(request): return render(request, 'testindex.html', {}) urls.py for customers from django.conf.urls import url from . import views # list of templates app_name = 'customer' urlpatterns = [ url(r'^basic_info/$', views.basic_info, name='basic_info'), ] urls.py for vendors from django.conf.urls import url from . import views # list of templates app_name = 'vendors' urlpatterns = [ url(r'^basic_info/$', views.basic_info, name='basic_info'), ] -

Import multiple Python scripts based on different virtualenvs with different versions of Django
I have a main script which has to perform some operations importing two old python scripts. Script 1 is based on Django 1.4, script 2 is based on Django 1.7.

How to save an object to be re-used in Django Rest Framework Serializer Method Fields?
The situation is as follows: 2 fields in my serializer uses the Serializer Method Field function to get their respective content. In each of these fields, I am calling the same, exact function to generate the content. Kinda like this: class ProductSerializer(serializers.ModelSerializer): field_1 = serializers.SerializerMethodField() def get_field_1(self, obj): content = generate_content(obj) return content.field_1 field_2 = serializers.SerializerMethodField() def get_field_2(self, obj): content = generate_content(obj) return content.field_2 As you can see, both the methods is calling the same function, with the same argument and therefore getting the exact same result. The generate_content function is very large, so I feel it would be best if I could save the content once, and use that to generate the two fields. How can I pull this off? Thanks! -
Django endless pagination appears to shows double entries
I use django endless pagination to load entries into a webpage. It appears that the same entry is loaded multiple times. To my understanding, that's not supposed to happen. My views.py def results(request): ajax = request.GET.get('ajax', False) if not ajax: materials = SubstanceCategory.objects.filter(material=1) return render(request, 'results.html', {'materials': materials}) @page_template('results/entry_index_page.html') # just add this decorator def results_material( request, template='results/entry_index.html', extra_context=None): material = request.GET.get('material',None) context = { 'entries': Photo.objects.filter( isPainting=1, substance_exists_labels__substance__name=material, substance_exists_labels__exists=True). \ annotate( C=Count('substance_exists_labels')). \ order_by('-C'), 'material':material } if extra_context is not None: context.update(extra_context) return render_to_response( 'results/entry_index.html', context, context_instance=RequestContext(request)) When called,results makes a list of available materials, and sends this to the webpage. The (related) html is shown here: <div id="holder"> {% for c in materials %} <div id="{{c.name}}" onclick="get_materials(this.id)"> <p> {{c.name}}</p> </div> {% endfor %} </div> <div > <div id="refreshed_later"> </div> </div> This looks like this.

Django REST Authentication with VUEJS and Axios

Django / Python dict values return each letter as item
I've got a problem which I just can't figure out. I've got a dictionary which I get from choices of a django form: forms.py class testForm(forms.Form): TEST_CHOICES = ( ("1", "One"), ("2", "Two"), ("3", "Three"), ) test_choice_field = forms.MultipleChoiceField(choices=TEST_CHOICES, widget=forms.CheckboxSelectMultiple) In my views.py I iterate through that dict of choices and try to return those choices in a string like this: "One / Two / Three" def test_func(request): if request.method == 'POST': form = testForm(request.POST) if form.is_valid(): test_choice_field = form.cleaned_data["test_choice_field"] empty_string = "" for numbers in test_choice_field: empty_string += dict(form.fields['test_choice_field'].choices)[numbers] subject = "[{}] is the Number you are looking for.".format(empty_string) What I wish for is that my "subject" holds the string "One / Two is the Number you are looking for", depending on which checkbox the user has checked. So if he/she picks all three checkboxes he get: "One / Two / Three is the Number you are looking for" and if it's only one "Two is the Number you are looking for" etc Now I simply just wanted to do a " / ".join(empty_string), but ended up getting this "O/n/e/T/w/o is the...."

Django model with more than 255 fileds

I´ve been looking for a workaround and in this question (Pass more than 255 arguments to a function) the answer suggests to use a list for the arguments, but I can not use this approach since the function is directly the constructor of the Model. I would appreciate any idea on how to workaround this situation. Thanks in advance! -

Django + ajax dynamic table content rotation
This is the second question in the row about my Django project. The code I use here is partly copied from this question:Stack Overflow What I aim to achieve is a dynamic table, that loops through objects in a list. Let's say I have 21 records. The table first displays records of 1 to 10, on the displaykala.html table. Then it replaces only the table content with records of 11 to 20(with AJAX, without page refresh. The new contents come from get_more_tables_kala.html, and those table rows coming from there, are appended to the displaykala.html table). At no point should the table be empty (UNLESS there is simply no objects to display). Basicly it always displays first ten records(even if there is only one). Then the code increments the startindex and endindex of the rows, and checks if there is records between those. If there is more than 10 records, it will empty the table and instantly load up the next records (as long as there is even 1 record). Else, the program should wait X amount of seconds, until checking again. The code has been going through various experimentations, I'm sorry for any dumb coding. I'm still learning Django and … -
Python - Compare birthdate
I have 2 variables which are 2 birthdates. I want to compare both for displaying a message telling 'Hey it seems you have almost the same age !" try : his_birthdate = player.profile.birthdate my_birthdate = request.user.profile.birthdate except: pass Well... I think if both persons are maximum 3 years of difference, we can considere that they have almost the same age. So I can do many conditions like this if you know what I mean : try : his_birthdate = player.profile.birthdate my_birthdate = request.user.profile.birthdate if his_birthdate > my_birthdate + 3: .... if his_birthdate > my_birthdate - 3: .... except: pass But I think there is a better solution ?
