Datetimepicker MM/YYYY Format
I'm attempting to implement the datetimepicker with just monthly selection. I've done this, but upon selecting a month, I get an error that indicates 'Enter a valid date.' I'm assuming django doesn't like the format of the date (i.e. MM/YYYY) given the fact that it's looking for something to fit into a DateField. Here is my form. class MonthlyForm(forms.Form): start_month = forms.DateField(required=True) def __init__(self, *args, **kwargs): super(MonthlyForm, self).__init__(*args, **kwargs) self.fields['start_month'].widget = DatePickerInput( options={ "format": "MM/YYYY", # moment date-time format "showClose": False, "showClear": False, "showTodayButton": False, "useCurrent": True, "ignoreReadonly": True, "keepInvalid": True, }, attrs={'autocomplete':'off'} ) Any thoughts on how to get around this would be appreciated. Even if I can somehow bypass the normal form validation for this field would work. I can do the validation inside of def clean. Thanks! -

Django how to link Users to Usermodel
Hello I am pretty new to Django and don't get yet fundamental ideas of Users. I was able to create a registration page to create users which are shown on the admin page in the "Authentication and AUthorization -> Users". Now I want the users to logg in and create their profiles. They should add some additional information like name, bio, picture etc. Every user should be able to add and see its own profile. To do that I created a model: class Profile(models.Model): firstname = models.CharField(max_length=50) lastname = models.CharField(max_length=50) bio = models.TextField() profile_pic = models.ImageField(upload_to="images/") def __str__(self): return self.firstname + ' | ' + self.lastname In my view and the html I am able to add these informations to the model. But HOW exactly can I relate this "Profile"-Model to the individual user? What do I miss here? -

Django/HTML - HTML not showing complete string from the context, rather only part of it
I am working on a Django site. This site has a form with preview button. How I would like it to work: Text entered in the input field on HTML. Preview button pressed. Python script runs in background. Form to retain it's values. What I have done: So far I have managed to a create form, a preview button, run the script and return the values as context to HTML and show it on the form. However the problem is, if the string has spaces. Form only shows first section of the string rather than whole string. Example: If I enter name as "John Smith" and press preview button. Form only shows me "John". Same if I do "London, United Kingdom". It shows me "London," I have looked onto Google and stackoverflow but couldn't find a solution to this, hence thought to ask here. I would appreciate if someone can guide me on this. views.py ''' nname = request.POST['name'] django_run_script() context = {'name': nname} ''' index.html ''' <div class="form-group"> <label class="label" for="name">Full Name</label> <input type="text" class="form-control" name="name" id="name" placeholder="Name" required value={{ name|default:"" }}> </div> ''' Thank you, Kind regards, Shashank -
Django allauth and google recaptcha on login page - any good solutions?
I'm getting this error error Exception Value login() got an unexpected keyword argument 'redirect_url' Exception Location: \allauth\account\views.py, line 159, in form_valid I would have thought there were some good solutions out there, but none work for me, it seems outdated? I'm using django-allauth and django-recaptcha 2.0.6 The login page shows the google recaptcha, but I don't think it's working at all. When I type in an incorrect password it says that it's incorrect even when I don't check the box. I've tried putting {{ form.captcha }} in html and it doesn't show at all. When I do type in the correct password with or without checking the box I get the error above. There must be an easy solution?

Limit number of images user can upload
I have a blog feature on my site, users can upload a single main image and multiple supporting images. The issue I am facing is I want to be able to limit the number of images a user can upload. I understand that I could use a for loop on it but if the user goes back later and adds more it would make the for loop useless. So I figured the best way to do this would be to add a field to the model that would count the number of images uploaded and then I can use an if statement to check if more than a said number of images have been uploaded. How would i go about getting the number of images and adding them to the post while it is being created. Or should I go about this a different way view @login_required def createPostView(request): currentUser = request.user postForm = PostForm() if request.method == 'POST': postForm = PostForm(request.POST, request.FILES) if postForm.is_valid(): PostFormID = postForm.save(commit=False) PostFormID.author = request.user PostFormID.save() for f in request.FILES.getlist('images'): test = PostImagesForm(request.POST, request.FILES) if test.is_valid(): instance = test.save(commit=False) instance.post_id = PostFormID.id instance.images = f instance.save() return HttpResponseRedirect("/") return render(request, 'blog/post_form.html', {'postForm': postForm, 'PostImagesForm':PostImagesForm}) -
Setting up gdal/osgeo Python library on Heroku
On my Windows machine, I have set up GDAL by following these instructions: downloading a wheel from Chris Gohkle's website and installing it using pip. pip install "C:/Users/andre/Downloads/GDAL-3.3.2-cp39-cp39-win_amd64.whl" This then gives me access to gdal like so: from osgeo import gdal How can I now re-create this for my Django App on Heroku? I have already followed the official Heroku instructions on installing GDAL with a buildpack. Although this is successful, I don't know how to install the osgeo library (and its gdal sub-module) on the remote Heroku machine.
