df.to_html() method is displaying the actual html on the webpage and not the representation it should (Django website)
I'm currently making a django website for a Software Engineering class. I'm having a problem with displaying a pandas dataframe using the .to_html() method. The webpage template is rendering the actual html code on the UI instead of the representation of the html code. I don't understand why and have looked for similar problems on the internet. I think I can't find a similar problem because I don't know the right words to use in the search engine to get the answer I want. The webapp template (called graphs.html) is displaying the actual code itself. Here is a code fragment: <table border="1" class="dataframe"> <thead> <tr style="text-align: right;"> <th></th> <th>itemId</th> <th>title</th> <th>endPrice</th> <th>location</th> <th>endTime</th> </tr> </thead> <tbody> <tr> <th>0</th> <td>283584749546</td> <td>1979 80 TOPPS #18 WAYNE GRETZKY ROOKIE CARD PSA 6 EX-MINT</td> <td>500.0</td> <td>Canada</td> <td>2019-11-17T08:08:30.000Z</td> </tr> <tr> <th>1</th> <td>163940352354</td> <td>1979 Topps Hockey Unopened Wax Pack Gretzky PSA ?</td> <td>103.5</td> <td>Rice Lake,WI,USA</td> <td>2019-11-16T16:27:42.000Z</td> </tr> <tr> <th>2</th> <td>293329130191</td> <td>1979/80 Topps Wayne Gretzky Rookie #18 High End PSA 6 RC Priced to Sell</td> <td>345.0</td> <td>Liberty Lake,WA,USA</td> <td>2019-11-15T22:04:27.000Z</td> </tr> <tr> As you can see, the UI is displaying html tags when it shouldn't.

Can't Login into Django Admin
What I know about AbstractUser and AbstractBaseUser is that AbstractBaseUser allow you to start from scratch but AbstractUser is to work with existng fields in USER. Similarly I created model using AbstractBaseUser and changed name of some fields like is_admin and is_staff but when I tried to login in Django Admin it doesn't allows. I figure out the problem and change name back to default and it worked. So if I wan't to login in to django admin what should I do. -
Adding a Custom DateTimePicker in a Django form
I'm quite new to Django, so I decided to build a simple app to test my skills. On one of the model forms, I have a DateTimeField, but that only defaults to a TextField. I would like to create a custom datetime picker with bootstrap, but I didn't know how to implement it. I followed a tutorial for Tempus Dominus Bootstrap 4 here. I have everything they say, but when I navigate to my form, it displays an error: 'BootstrapDateTimePickerInput' object has no attribute 'is_hidden'.

Query through intermediate models that returns multiple results, using Django Q object
How to follow an intermediate 'through' model, in a Q object? I'm trying to get a list of the ids of all Property objects that a User is a member of, in one query. A User is a member of a BusinessUnit through BusinessUnitMember.

django-select2: Select Field doesn't open when tabbed
In my simple Django App, I've implemented django-select2. I have a form with 2 fields: product and category. When I create a new product I first give it a title and than tab to the category-field, but the dropdown does not open automatically. Only when I press Space-Bar or Enter the dropdown opens. What can I do so that the dropdown opens automatically, when it is reached?

Filling ManyToMany field of a form in class based view - Django

get_form in ModelAdmin causing TypeError
This question refers to the issue I was having here which has not been solved. I have created a new simplified version of the MemoForm called AdminMemoForm to help me isolate the issue. After creating the new version of the form I have come to find that the get_form method is what is causing the TypeError: MemoForm object not callable. Here is a snippet of the new code that is throwing the error: Forms.py: class AdminMemoForm(forms.ModelForm): """ Memo creation form, related to: :model: 'memos.Memo', """ class Meta: model = Memo fields = ( 'title', 'content', 'important', 'word_file', 'receiver', 'read', 'unread', ) Admin.py: class CustomMemoAdmin(admin.ModelAdmin): form = AdminMemoForm def get_form(self, request, obj=None, **kwargs): form = super().get_form(request, obj, **kwargs) # if not request.user.is_superuser: # self.fields = ( # 'title', # 'content', # 'important', # 'receiver', # 'read', # 'unread', # 'word_file', # ) # self.filter_horizontal = ('casino',) return form() This is probably simple but I don't get why this error is arising.

Add custom url action parameter to django-cms
The common url action parameters in django-cms are for example: ?edit to enter Edit-mode, ?toolbar_off to disable/hide the toolbar. Now I'd like to add a new action parameter e.g. ?logout which just logs out the user no matter on which url he/she currently is. I'd tried to include this in the urls.py with the following pattern: url(r'^.*\?logout$', RedirectView.as_view(url='/admin/logout/')), I read in another SO answer that you shouldn't catch URL Params with an url pattern... Should I do this in a kind of middleware? Or where else? -

How to generate a magic number and populate it to the database upon user registration?
I am in search of a way to assign a random generated number-letter combination to a user upon registering on my page. So if a user registers on my site, there shall be a random generated number-letter combination (let's call it magic number) assigned to this user and populated to the PostgreSQL users table. Is there a common approach to do so? Would I have to define such function within the existing class or is there a different workflow?

I want to return all blog posts and projects with the same categories and display it in one page. I have 2 Django apps with 2 different models. What these two models has in common is a Category class, I understand that this will create 2 different tables in the db, 1 for blog category and 1 for project category. These are my models: Blog models.py class Category(models.Model): category_name = models.CharField(max_length=255) slug = AutoSlugField(populate_from='category_name', always_update=True, max_length=500, unique=True) class Meta: verbose_name_plural = 'categories' # to make sure a human readable string is returned and not Object def __str__(self): return self.category_name class Post(models.Model): title = models.CharField(max_length=500, unique=True) slug = AutoSlugField(populate_from='title', always_update=True, max_length=500, unique=True) summary = models.CharField(max_length=500) body = MarkdownxField() image = models.FileField() date_posted = models.DateTimeField(default=timezone.now) created_on = models.DateTimeField(auto_now_add=True) last_modified = models.DateTimeField(auto_now=True) categories = models.ManyToManyField(Category, related_name='posts') status = models.CharField(max_length=10, choices=STATUS, default='draft') author = models.ForeignKey(User, on_delete=models.CASCADE) class Meta: ordering = ['-created_on'] def __str__(self): return self.title Project models.py class Category(models.Model): category_name = models.CharField(max_length=255) slug = AutoSlugField(populate_from='category_name', always_update=True, max_length=500, unique=True) class Meta: verbose_name_plural = 'categories' # to make sure a human readable string is returned and not Object def __str__(self): return self.category_name class Project(models.Model): project_title = models.CharField(max_length=500, unique=True) slug = AutoSlugField(populate_from='project_title', always_update=True, max_length=500, unique=True) summary = … -
Data not getting replicated in my django master slave database architecture

Settings DATABASES = { 'default': { 'ENGINE': 'sql_server.pyodbc', 'USER': '---', 'NAME': 'main_db', 'HOST': 'localhost', 'PORT': '', 'PASSWORD': '---' }, 'slave_1': { 'ENGINE': 'sql_server.pyodbc', 'USER': '---', 'NAME': 'slave_1', 'HOST': 'localhost', 'PORT': '', 'PASSWORD': '---' }, 'slave_2': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'slave_2', 'USER': '---', …
