Django - How to change Textarea rows and columns in media query
I am having difficulties trying to understand how to change Textarea sizes so that my webpage is responsive. I currently have it set where the rows are 8 and cols is 60 which is perfect for viewing a webpage on a desktop. However, as i am trying to make my webpage responsive, i can not find a way to change the column value down to 30. I have thought about using css media query for this but can not understand how to change the values as they are currently set in the forms.py file as as shown below. I know users are able to resize the Textarea but i would like it if they can not resize the text area. So my question is if it is possible to make the Textarea responsive? forms.py: class UserSettings(ModeldForm): class Meta: model = Profile fields = ["name", "email", "profile_biography"] widgets = { 'profile_biography': forms.Textarea(attrs={ 'rows': 8, 'cols': 60, 'style':'resize:none'}), } -
What is the purpose of using GraphQL with MVC web frameworks (Laravel, Django, etc.), when currently built-in controllers does not make sense then?
What is the purpose of using GraphQL with MVC web frameworks (Laravel, Django, etc.), when currently built-in MVC framework controllers do not make sense then? Is there any simpler way/framework with just that purpose and is the reason for that just love for Laravel, Django and other MVC frameworks? If there is nothing similar and simpler, could we build something good and open-source just for that purpose, taking into account the increasing popularity of using that architecture and logic with GraphQL? I am open to suggestions and to start such a project. (It would be nice to hear suggestions/opinions from @taylorotwell, @adrian-holovaty, @simon-willison, Jeffrey Way) After a lot of experience with backend and frontend technologies, that question comes to me logically. Thank you :) -

Two versions of the same Django app: 1 for administration, 1 for queries only
I have two Django apps that share a database and also a number of models. App 1 is used to administrate the data via the admin page. App 2 is used only to query the data and present the data. The apps are running on different servers. My current solution is to run the exact same code in models.py on both apps. However, I have not run makemigration/migrate on app2. This solution works but makes me bothered by the fact that I have the same code in two models.py but only have one operational table in the database. What is the correct way of dealing with this situation? -

I have overridden the create method for ReviewRatings in ReviewRatingSerializer and creates ReviewImages in it also. I Have ReviewImagesSerializer also. So My doubt is How do I validate the images am looping through before saving it. Is there anyway to call ReviewImagesSerializer in create method of ReviewRatingSerializer to validate the files? #Serializer.py class ReviewImagesSerializer(ModelSerializer): class Meta: model = ReviewImages fields = ["images"] class ReviewSerializer(ModelSerializer): user = SerializerMethodField() review_images = ReviewImagesSerializer(many=True, required=False) class Meta: model = ReviewRatings fields = [ "user", "rating", "review", "created_at", "updated_at", "review_images", ] def get_user(self, obj): return f"{obj.user.first_name} {obj.user.last_name}" def create(self, validated_data): review_images = self.context["images"] reviews = ReviewRatings.objects.create(**validated_data) for image in review_images: ReviewImages.objects.create(review=reviews, images=image) return reviews
