How to render error or validation messages to ModelForm in 2022
I've spent several hours researching on the internet, especially the official Django documentation, but still it is not clear to me which is the best option in 2022 (since almost all questions I read on SO are > 6 yo) and there are diverse opinions on whether crispy forms is better or not. Is still crispy forms a recommended option? How can I (and what is the most recommended way to) get the typical validation error messages? Like: "this field is mandatory" or "this input accepts numbers only"? I've seen some Django pages using those default messages but I don't know how to show them in my ModelForm fields. Lets say I have the following model: class Project(models.Model): project_name = models.CharField(max_length=250, null=False, blank=False) status = models.CharField( max_length=250, null=True, blank=True, default=PROJECT_STATUS_DEFAULT, choices=PROJECT_STATUS, ) creation_date = models.DateField(max_length=250, null=False, blank=False) project_code = models.IntegerField(null=True, blank=True) notes = models.CharField(max_length=250, null=True, blank=True) And for the Project model I have the following ModelForm: class CreateNewProjectForm(ModelForm): creation_date = forms.DateField(widget=forms.DateInput(format = '%d/%m/%Y'), input_formats=settings.DATE_INPUT_FORMATS) #UK Date format class Meta: model = Project fields = '__all__' The view, when I try to create a new object Project: def add_new_project(request): context = {} if request.method == 'POST': form = CreateNewProjectForm(request.POST) if form.is_valid(): … -

Using fetch results to return element to component - React
I have a web app built with python/django and I'm trying to use React for the front-end. The app has a template with an empty div (#profile) that is populated via React. There is an attribute on the template that is used to fetch data from the back-end. The data is passed as props to the main function/component (Profile) to instantiate the state. let username = document.getElementById('profile').getAttribute('data-profile'); fetch(`/getFollow/${username}`) .then(response => response.json()) .then(results => { ReactDOM.render(<Profile profile={username} followers={results.follower_count} following={results.following_count}/>, document.querySelector("#profile")); }) The Profile component returns the html elements and contains another function/component (FollowButton) function Profile(props) { const [state, setState] = React.useState({ follower_count: props.followers, following_count: props.following, profile: props.profile }); return ( <div> <br></br> <div class="row justify-content-center"> <h2 id="profile">{state.profile}</h2> <span> <FollowButton profile={state.profile}/> </span> </div> <div class="row justify-content-center"> followers: {state.follower_count} | following: {state.following_count} </div> <br></br> </div> ); } The FollowButton used the passed in prop to make another fetch and based on the results dynamically return a button element. function FollowButton(props){ fetch(`/getFollow/${props.profile}`) .then(response => response.json()) .then(results => { if (results.isFollowing == "True"){ //Return Following button //console.log('following'); <button class="badge badge-pill ml-2 btn-primary">Following</button> } else if (results.isFollowing == "False"){ //Return Follow button //console.log('follow'); <button class="badge badge-pill ml-2 btn-secondary">Follow</button> } else if (results.isFollowing == "Self"){ //No button … -

Application Error while my Django app successfully deployed
I am leaving a question of why I got an application error after deploying Django successfully. It seems like I could deploy my Django app to Heroku, but I got an error when I wanted to see my app by pressing the "open app" button on the Heroku dashboard. I am ignoring the database, which is Postgres, now. If I only care about the app without any data, I think I should be able to run the code on the Internet. Here is my source code on github, so I want you to check this out. Thanks so much in advance. -
Access domain name inside model function
I have this model class ArticleWithLinks containing method bodyWithLinks(). It returns article's body(text) + strictly formatted string of links formated like: '[3]: http://my.doma.in/articles/some-slug "Good article!"' joined by '\r\n'. For sure, it could be done in more elegant manner but... anyway ;-) It has to be done this way because body+links will be later together processed by markdown while rendering template. Referenced link details like [id] or some-slug or "Title" (packed in other class) I can easily obtain within models.py and even dynamically add /articles/ using get_absolute_url() method. However, as you probably know, this method returns URL without the domain name. I fully understand the concept that models shall not know about context of their usage (request) but I have to inject it before I pass it to markdown processor called in view's template. What is the best way to do that? Pass request (or even better - domain only) to model's bodyWithLinks() as a parameter and join it inside. I've googled it and found something like simple template tag Somehow retreive it inside model function - I've seen Site class from contrib, that contains domain as well Somehow wrap bodyWithLinks() model's method inside views.py and pass it to template with … -

I have a few models: class Page(models.Model): date = models.DateField("Post date") title = models.CharField(max_length=255) chinese = models.TextField() base = models.TextField() published = models.BooleanField() premium = models.BooleanField() json = JSONField(default=dict, null=True, ) category = models.ManyToManyField( Category) calculated_hsk = models.DecimalField( default=1, max_digits=3, decimal_places=2) display_hsk = models.ForeignKey(HSKLevels, on_delete=models.SET_NULL, null=True) image = models.ImageField(upload_to=imageFile, null=True, max_length=255) sound = models.FileField(null=True, max_length=255) url = models.URLField(max_length = 255, null=True) class Sentence(models.Model): sentence = JSONField(default=dict, null=True, ) article = models.ForeignKey( Page, on_delete=models.SET_NULL, null=True ) language = models.ForeignKey(Language, on_delete=models.SET_NULL, null=True) class Translation(models.Model): translation = models.TextField() sentence = models.ForeignKey( Sentence, on_delete=models.SET_NULL, null=True ) language = models.ForeignKey(Language, on_delete=models.SET_NULL, null=True) I want to be able to filter by sentence language, so that I only get the current sentence languages that I want. I have a DRF endpoint setup like this: class ArticleView(generics.ListAPIView): queryset = Page.objects.select_related().all() serializer_class = ArticleSerializer filter_backends = (filters.DjangoFilterBackend,) pagination_class = LimitOffsetPagination ordering_fields = ['date'] filter_class = MultiValue And a filter like this: class MultiValue(filters.FilterSet): published = filters.BooleanFilter(field_name='published') premium = filters.BooleanFilter(field_name='premium') category = NumberInFilter(field_name='category', lookup_expr='in') calculated_hsk = NumberInFilter(field_name='calculated_hsk', lookup_expr='in') display_hsk = NumberInFilter(field_name='display_hsk', lookup_expr='in') start = filters.IsoDateTimeFilter(field_name="date", lookup_expr='gte') end = filters.IsoDateTimeFilter(field_name="date", lookup_expr='lte') language = filters.CharFilter(field_name="sentence.language.lang_code", lookup_expr='in') And serializers like this: class SentenceSerializer(serializers.ModelSerializer): class Meta: model = Sentence depth = 1 fields = … -
'member_descriptor' object cannot be interpreted as an integer when looping through the timedelta.day
Am trying to filter through the number of days a users birthday is coming up. but whenever i filter through users upcoming birthdays for some reason I keep hitting this error 'member_descriptor' object cannot be interpreted as an integer, I have looked on stack overflow to find a solution but so far all seems not to fix my current challenge. I think the error stems from the for loop with deltatime.days, How best can i loop through the days in deltatime.days ? def upcoming_birthdays(request): birthdays_today = [] friend_list = FriendList.objects.get(user=request.user) #get all people with birthday today for p in friend_list.friends.all(): if p.isBirthdayToday(): birthdays_today.append(p) #get and format today's date today = date.today() suffix = _getSuffix(today) today_date = '{}{} {}'.format(today.day, suffix, today.strftime("%B")) # All upcoming birthdays friend_list = FriendList.objects.get(user=request.user) birth_list = friend_list.friends.all().distinct() today = date.today() upcoming_date_list = [] upcoming_date_list.extend(list(birth_list.filter(birth_date__month=today.month, birth_date__day=today.day))) next_day = today + timedelta(days=1) # this where am looping through the days for upcoming birthdays for day in range(0, (timedelta.days)): upcoming_date_list.extend(list(birth_list.filter(birth_date__month=next_day.month, birth_date__day=next_day.day, birth_date__isnull=True))) next_day = next_day + timedelta(days=1) #return template plus context context = { 'birthdays_today': birthdays_today, 'today_date': today_date, 'upcoming_date_list': upcoming_date_list, } return render(request, 'account/birthdays.html',context) here is the traceback exception Traceback (most recent call last): File "C:\Users\Umar\Desktop\dreams\env\lib\site-packages\django\core\handlers\exception.py", line 47, in inner … -
how to change width of list rows in django admin

django-social-auth not redirecting to provided next query param for SAML login
I have a django application that uses django-social-auth and allows for three types of SSO authentication, Google, Office 365, and SAML2.0. In the case of SAML2.0, the application allows the end user to specify their own IdP, and to enable that, we have a custom Database SAML Auth class, that allows us to store the users IdP information in the database, and log the user in. This works as expected, and users can sign in with SAML, Google, or Office 365, no problem. The challenge is when I need to be redirected to a specific URL once the login has completed. This is working as expected for Google and Office 365, but not for SAML login. As an example, I have a mobile application that authenticates via OAUTH to the django web application. When that mobile application starts its oauth flow, it goes to the authorization URL, and the gets forwarded to login. The path looks something like this: https://myapp.com/oauth/authorize/?client_id=something https://myapp.com/login/?next=/oauth/authorize/?client_id=something (after selecting sign in with SAML login method) https://myapp.com/login/subdomain/?next=/oauth/authorize/?client_id=something Redirect to IdP Redirect back to assertion consumer url https://myapp.com/login/sso/saml/complete/ Redirect to account page https://myapp.com/manage/ (not https://myapp.com/oauth/authorize/?client_id=something as expected) The frustration of course is that this breaks the oauth flow …
