How can I get some value from the select option django form?
I would like to know if django-forms have some way to get the value from select > option html tag. I know I can do it using something like JQuery, but I would like to know if there is some way to handle this in the client side using any django feature. -

Want to make a user detail page as 'example.com/username' displaying their info, posts etc
I'm making a django site and using 'allauth' module for authentication. I've used the adapters so that the user is redirected to example.com/username but instead of it leading to homepage, i want it to lead to a page dedicated to the user profile containing their posts, info etc. and they can add more info to it. I have tried searching on the internet but couldn't find an appropriate solution. this is the adapter code i've used to redirect after login, i found this code in the documentation of allauth. class MyAccountAdapter(DefaultAccountAdapter): def get_login_redirect_url(self, request): path = "/{username}/" return path.format(username=request.user.username) So, I want to know how can i create a separate profile page for users, and when someone not logged in opens that profile link, they can see their posts etc. like in instagram. -
Manually add form errors in between inputs
I left some space between the inputs because I want to manually add form errors there, however extra space is appearing below the error message. I am trying to make the error message exactly fit available space without form resizing. This is happening because I applied padding-bottom: 10px; on my <td> but I'm not sure how could I accomplish this otherwise. I have tried to use CSS grid instead of the table, and set grid-row-gap: 10px; but the result was similar. How can I make the error message fit the available space without form resizing? The error message is in this format: <ul class='errorlist'> <li>Please use another email, this one is already taken.</li> </ul> ...and it does not exist until the button is pressed and the invalid form was submitted. Here is my code: forms.py from django import forms from django.contrib.auth.models import User class RegistrationForm(forms.ModelForm): email = forms.EmailField(max_length=200, help_text='Required') password = forms.CharField(label='Password', widget=forms.PasswordInput) password2 = forms.CharField(label='Repeat password', widget=forms.PasswordInput) class Meta: model = User fields = ('username', 'email', 'first_name', 'last_name') def clean_password2(self): cd = self.cleaned_data if cd['password'] != cd['password2']: raise forms.ValidationError('Passwords do not match.') return cd['password2'] def clean_email(self): email = self.cleaned_data['email'] if User.objects.filter(email=email).exists(): raise forms.ValidationError( 'Please use another Email, that is … -

upgrading python for django site running on Apache & wsgi
I'm trying to switch a django site from running in python 3.6 to python 3.7 on Ubuntu 16.04. To do so I created a new environment in the same path as the old and have re-installed all of the dependencies. The Apache server, however, fails with the following error: Fatal Python error: Py_Initialize: Unable to get the locale encoding ModuleNotFoundError: No module named 'encodings' Which error, after a bit of research, seems to be due to the WSGI configuration, as per: You cannot for example force mod_wsgi to use a Python virtual environment created using Python 3.5 when mod_wsgi was originally compiled for Python 2.7. This is because the Python library for the Python installation it was originally compiled against is linked directly into the mod_wsgi module. In other words, Python is embedded within mod_wsgi. When mod_wsgi is used it does not run the command line python program to run the interpreter and thus why you can’t force it to use a different Python installation. from: https://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html thanks to: Django Apache wsgi changes python version The OP in the above ended up just wiping the setup clean and starting from scratch. This seems a bit extreme to me, as it … -

PythonAnywhere Issue: Your processes have been killed because a process exceeded RAM Limit
I am getting this warning email from PythonAnywhere on every single request to my website. I am using spaCy and Django and have just upgraded my account. Everything seems to work fine, though. Except I am receiving warning emails, that is. I have only 2 GB RAM on my local machine and it can run my app along with a few other apps too without any issues. Then why is 3 GB RAM not enough on PythonAnywhere? (I also have 3 GB disc space on PythonAnywhere, of which only 27% is used up.) I have tried searching for the answers on their forum and on the internet in general but I have not got any clue about the issue. -

How to make a request using jQuery to a django server to refresh infos on page
I made a website in python using Django. My site allows you to control lights while indicating if the light is on or not. I'm looking for a solution that could make a simple request with data to the server and send data back to the client without updating the entire page but only a part of it. My ideal would be for the client to make a request to the server with identification data. Then, the server returns the updated data that the user is allowed to have. Is that possible to make a JavaScript to do that ? And the server, how it can return data to the client ? -

Model based caching instead of view based caching in django
I am working on a django application. The main task of the application is providing suggestion like "Should I go outside today?". There is only a single endpoint to get the suggestion such as example.com/. The main logic for providing the suggestion is: Does the user has any pending task today? (querying from UserTaskModel) Is today's weather is comfortable? (calculating weather forecasting) If two user try to fetch data at the same date then the UserTask query will be different. But weather forecast query task will be same. If I use view based django caching then the weather forecast query will be execute for each user. But I want to cache the weather query data for all user at a same date. It can view implement by creating different view for the weather. But I don't want to use another endpoint for the weather. Django cache set-get method can be use for this task. But is this way is the best way to do this type of task? In my example I use a simple weather calculation query depending the the date. But is this technique is good for complex query? -
