Problem with showing images in django admin
I am going through the tutorial and I was wondering about something: I have an app called projects with a model: class Project(models.Model): title = models.CharField(max_length=100) description = models.TextField() technology = models.CharField(max_length=20) image = models.FilePathField(path='/img') The images are in app/static/img. I can see them on the website: <img class="card-img-top" src="{% static project.image %}"> But when I go into admin, after clicking on the project object it crashes with Exception [WinError 3] The system cannot find the path specified: '/img' Official Django tutorial actually says that you need to put static files into app/static/app, but when I put them into projects/static/projects/img they are no longer on the website and the admin still crashes. I also put the files into projects/static/projects/ and now the admin works, but the website doesn't show the pictures and the dropdown menu in admin also doesn't actually show the images, so I guess nothing has access to these images anymore. My settings are STATIC_URL = '/static/' Is there a document where it clearly says what should be in the settings and where should the static files go? I am super confused about this. -

django/react - How does including a redirect inside my URL for password-reset work?
I created a microservice to reset a users password when they can't remember it. Here is my flow: User sends post message to my django backend requesting a password reset via my frontend react form. If the user is in my db, then a token and uidb64 get generated. An email arrives in their inbox directing them to a link where they can create a new password. The url is holding token and uidb64 data to verify authentication/password rest. Once link in email is clicked and verified for correct token/uid credentials. [Here is where I'm confused ->] It, being the link, ideally redirects the user to my frontend react form that allows them to create a new password. This is the part of my flow I'm confused. Currently the URL redirects them to the standard drf page, as expected to. But how can I achieve this link to redirect them to my react-frontend post credential verification, token and uid. I've addred a redirect link in the URL, but it's empty because I'm not sure what to put in it/not sure how to get my view, PasswordTokenCheckAPI() to redirect From react, the new password form is then submitted to my django … -

How to import and instantiate classes imported from dll using ironpython?
I have DLLs from a project implemented in C#, but i want to create a python (django) solution based on that project. For that purpose I'm using ironpython to import and load the DLLs and I'm creating a handler to handle them.

Deploying a django rest framework api that uses react for the frontend
I am currently working on a project that that has a react frontend from which I fetch information from the rest framework api and then display it. It is the first time I deploy something like this and I have found it very confusing to understand what is the best way to deploy this. What I Have Tried I tried deploying on heroku without really knowing what I was doing and then the following happened. My react app shows perfectly on heroku without any problems, but when the fetch funcitons are called there was an error that said connection refused. Then I realized that my django server had to be running in my computer in order to react o be able to fetch the information. I thought that the django server would also get deployed but apparently I have to deploy separately I guess. I have been searching for a while and I found something about nginx, digital ocean and docker but I didn't understand what would I have to do in this case. Anyone knows what should do I do in this case? -
Password changing view is not working correctly
So I'm trying to see if user matches their old password, if they don't then it will give a message saying "Your old password in incorrect" but if they match their old password then it should check if user matched new and confirmed password correctly, if they did not then it should give a message saying "Your new passwords do not match", But even when I match the old password correctly it always says "Your old password is incorrect" even if it is correct. views.py @login_required def userchange(request): if request.method == 'POST': # user = User.objects.get(username=request.user.username, password=request.POST['Old password']) if User.objects.filter(username=request.user.username, password=request.POST['Old password']).exists(): if request.POST['New password1'] == request.POST['New password2']: User.objects.update_or_create(username=request.user.username, password=request.POST['New password2']) return render(request, 'main/change.html', {'error':'Your password has been changed succesfully!'}) else: return render(request, 'main/change.html', {'error':'Your new passwords do not match'}) else: return render(request, 'main/change.html', {'error':'Your old password is incorrect'}) elif request.method == "GET": return render(request, 'main/change.html') change.html <h1>Note: You will be logged out</h1> <h2>{{ error }}</h2> <form method="POST"> {% csrf_token %} <input type="password" placeholder="Old password" name="Old password"> <input type="password" placeholder="New password" name="New password1"> <input type="password" placeholder="Confirm password" name="New password1"> <button type="submit">Change password</button> </form> -
What could be the problem of django run error
My Django project used to work well the day before but it was not working when I run the next day. The following is the error I am getting. I didn't change anything and yet it did not work. When I run my project, the following error occurs. The project name is 'carpooling' and the the database user is 'Jigme'. I think the last line points the error towards the database which I didn't change anything. Please help me. Your help will be appreciated.
