javascript array object doesn't work with Hicharts when defined through jinja (Django 2.0)
I want to use data passed through a django (2.0) view to my html template - but in JavaScript. I need it to plot an area chart with Highcharts.

How to make Django validators dynamic?
I am new to Django. I am taking over a Django project developed by someone else. They took the basic form validators from here: https://docs.djangoproject.com/en/2.0/topics/auth/passwords/ So if I open settings/common.py I see: AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', 'OPTIONS': { 'min_length': 9, } }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] My project manager is telling me that she wants these validators to happen while a person is typing, rather than when the form is submit. So I need to somehow make these validators trigger onBlur as the cursor leaves each field. How is this done in Django? -

User input associates to photo
Working on a blog, where users can create new posts and input a keyword to have a picture associated with that keyword provide a photo for the post. For example: 1) User inputs keyword: 'Pizza' 2) The form page that the user is on either: a) uses that keyword to provide an image associated with it or b) uses that keyword to provide a couple images that the user can then choose from for the image for the post 3) The selected image is then associated with that post Does anyone have suggestions on how to implement this? I'm keen to work on it, but can't even think where to start. Is there a google images plugin that i could use? Or any sample codes? -
forms select2 POST is empty
I'm seeking guidance to get me going in the right direction. My professor is at a loss. I'm having issues with the POST in my form for the select2 multiple fields. I have a Yes/No flag, that determines which select 2 select option to show. The javascript below works great for the show/hide. $(document).ready(function () { $('#option').change(function () { $this = $(this) $('.select_box').each(function () { $select = $('select', this); if ($select.data('id') == $this.val()) { $(this).show(); $select.show().select2(); } else { $(this).hide(); $('select', this).hide(); } }); }); }); My form has a Yes/No/NA option, which dictates what select 2 box to show using the javascript above. <select name ="option" class="form-control " id="option"> <option value="1"> Yes</option> <option value="0"> No</option> <option value="2"> N/A</option> </select> My form POST is handled with the general POST option as shown below: <form action = "{% url 'final' %}" form method = "POST"> Inside my form I have the .select_box div class. The select 2 option gives the correct fields and populates the multi-select correctly. <div id = "div_yesselect" class="select_box"> <script src= "{% static '/accounts/option_select2.js' %}" type="text/javascript"></script> <select data-placeholder="Please select your course(s)?" data-id="1" class="js-example-basic-multiple" multiple="multiple" id = "id_courseselect" value = "{{course.id}}" style="width: 1110px" > {% for course in courses%} … -
Django URL keeps being longer

Django 2.0 URL regular expressions
I'm trying set an offset but I want to limit it to a maximum of 99 hours by only allowing either one- or two-digit numbers but I'm not sure of the syntax to use with Django 2.0. I've tried to look for updated documentation but I can't find it, maybe I missed it but I did look before posting here. Here is the code in my views.py file: # Creating a view for showing current datetime + and offset of x amount of hrs def hours_ahead(request, offset): try: offset = int(offset) except ValueError: # Throws an error if the offset contains anything other than an integer raise Http404() dt = datetime.datetime.now() + datetime.timedelta(hours=offset) html = "<html><body>In %s hour(s), it will be %s.</body></html>" % (offset, dt) return HttpResponse(html) Here is the code from my urls.py file, this allows me to pass an integer but I want to limit this to 1- or 2- digit numbers only: path('date_and_time/plus/<int:offset>/', hours_ahead), I've tried path(r'^date_and_time/plus/\d{1,2}/$', hours_ahead), but I get the Page not found (404) error.

Restricting all the views to authenticated users in Django
I'm new to Django and I'm working on a project which has a login page as its index and a signup page. The rest of the pages all must be restricted to logged in users and if an unauthenticated user attempts to reach them, he/she must be redirected to the login page. I see that @login_required decorator would make a single view restricted to logged in users but is there a better way to make all the views restricted and only a few available to unauthenticated users? -
How to access one to many relationship after bulk_create in Django

I'm doing it as follows: person = Person(foo="bar") person.save() posts = [Post(person=person, text="post1"), Post(person=person, text="post2")] person.posts.bulk_create(posts) # Now I want to have an access to the person.posts and pass it to a serializer return PostSerializer(person.posts.all(), many=True).data When I execute, it doesn't populate the relationship => it's empty. I want to perform this without additional query to the database. Is that possible? -
Django: Using Template Tags with ckeditor
I'm using RichTextUploadingField from the ckeditor package for django for my flat pages. I need to insert some urls but I don't want to hardcode them as I'd like to be able to change the urls in the future. If I could do this by using django template language in ckeditor it would be great but I'd be happy just to soft code the urls into the field. -

django admin for multiple user types
I've an app that deals with multiple user types. I need a way for differentiating them in the admin site. Some code to illustrate. First I created a User model class that inherits from AbstractUser class User(AbstractUser): is_partner = models.BooleanField(default=False) is_client = models.BooleanField(default=False) email = models.EmailField(unique=True) Partners and Clients users has different data: class ClientProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) ... class PartnerProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) ... Client profile is created through SignUp form I provide, after that, users can update their own profile. In the other hand, Partner profile is created by myself as admin, and I need to do it through django admin site. So, how do I register two version of the same model? and provide different names for showing in the admin index? What I did was to change just the queryset in the ModelAdmin class, and register it twice, one for Client and another for Partner but it raises me django.contrib.admin.sites.AlreadyRegistered class ClientProfileInline(admin.StackedInline): model = ClientProfile can_delete = False verbose_name_plural = 'Client Profile' fk_name = 'user' class ClientUserAdmin(UserAdmin): inlines = (ClientProfileInline, ) def get_queryset(self, request): qs = super().get_queryset(request) return qs.filter(is_client=True)#HERE it is the flag for differentiating between Client and Partner def get_inline_instances(self, request, obj=None): if … -

Get data in model methods from multiple models - Django
I'm quite new to Django (Python too) and learning it by doing. I'm playing with Django admin site. I've created two models and successfully registered in admin. The data is nicely displayed for the fields given in list_display. I want an another table in admin, which displays data from both the tables by processing with some logic.
