issues with python virtual environment
I am facing following 2 issues: python command is not using the virtualenvwrapper python. After activating my virtual environment if I type python then the code still uses the native python libraries. I can easily install libraries etc with pip to my virtual environment but I cannot run any command using python. e.g. if I execute $ ./manage.py runserverthen it is fine and I can run a django server but if I try $ python manage.py runserver or even just $ python then it uses the native python libraries and that should not happen This is while using iterm or terminal in osx. I have never faced this problem in any linux based os While using any os (linux based or osx), the workon command doesn't work inside any shell script, while it works normally in a terminal os: osx -

request.user.is_authenticated() consistently returns false (Django)
The problem I'm having I'm currently using Django v1.9 as a back-end for my Angular2 app (I'm not using the Django REST Framework yet, just using Django's authentication system and dumping JSON) I'm trying to authenticate the user, log them in, and then allow them to edit their profile. The first two steps seem to work. However, I'm having some trouble with request.user.is_authenticated() - it consistently returns false, even though I have called the login() function on the user previously. The part that seems to work @csrf_exempt def userlogin(request): body_unicode = request.body.decode('utf-8') body = json.loads(body_unicode) input_u = body['uname'] input_p = body['pword'] worked = False user = authenticate(username=input_u, password=input_p) if user is not None: login(request, user) context = { "login_data" : { "logged_in" : True, "user_id" : user.id } } else: context = { "login_data" : { "logged_in" : False, "user_id" : 0 } } return HttpResponse(json.dumps(context), content_type="application/json") The part I'm struggling with @ensure_csrf_cookie def user(request): is_auth = False if request.user.is_authenticated(): is_auth = True context = { "is_auth" : is_auth } return HttpResponse(json.dumps(context), content_type="application/json") Note: I'm using is_authenticated() (function) and not is_authenticated (property) as I'm on Django v1.9 and not v.1.10 (source).

django specific url/view that wont modify the session expiry date?
As I see each time the session is changed, i.e request.session['last_date'] = datetime.datetime.now() for example, the expiry_date is changed too. Can I create an exception for that? I want to use the expiry_date as a timeout for the session, but I have a JS code in the client which send requests every few minutes, thus always extend the session expiry_date. I want a way (simple, I hope) to write to the session without extending this date. -
Angular2 and Django: CSRF Token Headache
The Issue I'm Having I'm making an Ajax POST request from my Angular2 client to my Django (v1.9) backend (both on localhost, different ports). I'm not yet using the Django REST framework, I'm just dumping the JSON in Django without any add-ons. I have been issued a csrf token by the server, and I'm manually sending it back in the HTTP headers (I can see it there when I make the call). However, I still get the error from django: Forbidden (CSRF cookie not set.) I've read a number of other threads, and tried a few things, but still can't get Django to accept the CSRF token. Client side code: private _editUserUri = "http://127.0.0.1:8000/search/edit/user/"; constructor(private _http: Http){} getCookie(name) { let value = "; " + document.cookie; let parts = value.split("; " + name + "="); if (parts.length == 2) return parts.pop().split(";").shift(); } validateData(userdata) { return true; } editUser(userdata) { console.log("UserService: createUser function called"); console.log(JSON.stringify(userdata)); if(this.validateData(userdata)) { let headers = new Headers({ 'Content-Type': 'application/json', 'X-CSRFToken': this.getCookie('csrftoken') }); let options = new RequestOptions({ headers: headers }); return this._http .post( this._editUserUri, JSON.stringify(userdata), options) .map(res => { console.log(res.json()); return res.json(); }) } } Screenshot of csrf token in header (x-csrftoken).

How to auto populate updated_by in abstract model that is used by all other models in my app?
I usually use some decorators but this time decided to use the abstract model to have all my common fields. How do I auto populate updated by. I saw some old answers saying it is not possible to do in the model . DRY way to add created/modified by and time Anything changed+ in 5 years? how you usually do it? So far it looks like I will have to use both decorator django-author with Common model for other fields. class CommonInfo(models.Model): created = models.DateTimeField("creation date", auto_now_add=True) modified = models.DateTimeField("modification date", auto_now=True) description = models.TextField() is_active = models.BooleanField(default=True) updated_by= class Meta: and to have more control abstract = True -
Display additional content panel based on boolean block in Wagtail Editor Interface
I want to add a boolean block to my Wagtail model and show a content panel field only if it is checked.

Django query not considers special characters
I've come across a problem with special characters on a django query (Django 1.9.2). I've created a model that stores a word in it, and I'm feeding that model with words from a Spanish dictionary, using code as follows: MyModel.objects.get_or_create(word=myword) And now I've realized that words containing special characters haven't been added, so, for example, there is only one row of MyModel in the database for año and ano! And when I query the database I retrieve the same object for these two queries: MyModel.objects.get(word='año') MyModel.objects.get(word='ano') ...and no, those words are not the same ;D I would want to create one object for each, of course. -

Django INSTALLED_APPS not installed and preventing makemigrations
I recently pulled a repo from GitHub to get a local copy on my machine. The backend uses Django, and I was working on updating some models. Since I changed some models I wanted to run ./manage.py makemigrations. At first there was an issue with python2 vs python3, so I changed the #!/usr/bin/env python to #!/usr/bin/env python3.

In forms.py: from django.forms import ModelForm, Textarea from .models import Batch class BatchForm(ModelForm): class Meta: model = Batch fields = ('recipe', 'date', 'original_gravity', 'final_gravity', 'gravity_units', 'notes') widgets = {'notes': Textarea(attrs={'cols': 40, 'rows': 10})} in views.py: (notice the instance=batch argument, this should pre-populate the form correct?) def batch_entry(request, batch_id): if int(batch_id) > 0: batch = get_object_or_404(Batch, id=batch_id) form = BatchForm(request.POST, instance=batch) context = {'BatchForm': form, 'batch': batch } else: form = BatchForm() context = {'BatchForm': form, 'batch': None } return render(request, 'logger/batch_entry.html', context) the batch_entry.html template: {% if batch.id > 0 %} <h1>{{batch.date}}</h1> <h3>{{batch.recipe}}</h3> <form action="{% url 'logger:batch_entry' batch.id %}" method="post"> {% csrf_token %} <table> {{BatchForm.as_table}} </table> <input type="submit" value="Submit"> </form> {% else %} <h1>New Batch</h1> <form action="{% url 'logger:batch_entry' 0 %}" method="post"> {% csrf_token %} <table> {{BatchForm.as_table}} </table> <input type="submit" value="Submit"> </form> {% endif %} <form action="{% url 'logger:index' %}" method="post"> {% csrf_token %} … -
How to change a layout of a crispy form by using radio buttons
I am using crispy-forms to render forms. I have model form that I want it to be filled with 2 ways. The first way is users can fill out fields 1 to 6 and leave fields 7 to 15 blank, and fileds 7 to 15 can be filled using a updateview method. The second way is to fill out the 15 fields all by once. I idea is two use tow radio button on the top of the form say 'layout-1' and 'layout-2' and the form layout can be changed by clicking the radio buttons. Can anyone give me some clue on doing this? My code as follows: models.py class test(models.Model): station= models.ForeignKey(station) type = models.CharField(max_length=5, choices=( ('inner', 'inner'), ('outer', 'outer'), )) serialNO = models.CharField(max_length=20) content = models.CharField(max_length=100) person_1 = models.CharField(max_length=10, blank=True) ordering_time = models.DateTimeField(null=True, blank=True) starting_time = models.DateTimeField(null=True, blank=True) ending_time = models.DateTimeField( null=True, blank=True) person_2 = models.CharField(max_length=10) person_3 = models.CharField(max_length=10) person_4 = models.CharField(max_length=10,blank=True) person_5 = models.CharField(max_length=10,blank=True) person_6 = models.CharField(max_length=10,blank=True) steps=models.PositiveIntegerField() status=models.CharField(max_length=20,choices=( ('0', 'canceled'), ('1', 'will do'), ('2', 'done'), ) ) forms.py class testForm(forms.ModelForm): form_type=forms.ChoiceField(required=False,choices=((1,'layout-1'),(2,'layout-2')),widget=forms.RadioSelect(),label='select layouts') form_layout_1=Layout( 'form_type', 'station', 'type', 'serialNO', 'content', 'person_2', 'person_3', 'steps', 'status', ButtonHolder( Submit('submit','Submit') ), ) form_layout_2=Layout( 'form_type', 'station', 'type', 'serialNO', 'content', 'person_1 ' 'ordering_time' 'starting_time' …
