DRF nested serialization without raw sql query
I've stuck with this problem for few days now. Tried different approaches but without success. I have two classes - Poll and PollAnswer. Here they are: class Poll(Model): title = CharField(max_length=256) class PollAnswer(Model): user_id = CharField(max_length=10) poll = ForeignKey(Poll, on_delete=CASCADE) text = CharField(max_length=256) what is the right way to get list of polls which have answers with used_id equal to the certain string with nested list of that user's answers? like this: { 'poll_id': 1, 'answers' : { 'user1_answer1: 'answer_text1', 'user1_answer2: 'answer_text2', 'user1_answer3: 'answer_text3', }, } and if it's the simple question i probably need some good guides on django orm. the first thing i tried was to make serializer's method (inherited from drf's ModelSerializer) but got an error that this class can't have such method. after that i tried to use serializer's field with ForeignKey but got polls nested in answers instead. right now i believe i can make Polls.objects.raw('some_sql_query') but that's probably not the best way. -
How to get and post data (serialize) in a desirable way (in both ways) using react & django-rest-framework
I'm working on a project where API based on django-framework works as a server, front is created using react/redux. My problem is, that i've written a few serializers regarding Django Users & Project. While fetching the project or projects i receive json in format: { "project_leader": { "id": user_id, "last_login": ..., "username": ..., "first_name": ..., "last_name": ..., } "project_name": string, "project_description": string, "done": boolean, "due_date": time } project_leader(User) data are the same format like in a serializer below. The data format i want to receive is nice, but the problem starts when i try to create new one. When i format the data in react component in a way like in serializer - i receive errors like: Cannot parse keyword query as dict When i format the data in a "django-way" - for example a user is only a user id, not the whole dictionary - the project is created but i what i receive back in a user field is just a user id, so i cannot dispatch action to the reducer because i don't have all the user data i map. Models: class Project(models.Model): project_leader = models.ForeignKey(User, on_delete=models.CASCADE) project_name = models.CharField(max_length=128) project_description = models.TextField() done = models.BooleanField(default=False) due_date … -
Right html side-bar covered by fixed html table
I'm not sure exactly what's happening here. It looks like there is the table element which shows the table but appears to expand white space almost all the way to the right side of the page which is covering my right side-bar and I don't know how to make it show up. Could someone confirm if this is the case or not and potentially give me some clues as to what to to do fix? I've tried changing the margins on both bits of html from Px to % and a few other things and can't figure it out. Sorry if this is a really long post, not sure what to cut out.

How to validate input in a field on webpage without reloading the webpage?
(I am a beginner in django and html) How can I weed out spam entries in a particular field while taking input from a user? Also, how to show a message to the user that the entered value is not accepted because it's a spam, without reloading the webpage. For eg., in the field shown in image, if the user enters a number or something like test123 or something else that's not a proper name, my webpage should show a message to the user without loading the webpage that the entered value is not valid. I am also okay with putting a button that says validate to validate this name field value. How can I achieve this using Django+html+jquery? -

Django on IIS large file upload
I am trying to host a simple Django web application on a windows 10 machine with IIS 10 with FastCGI. As I my program is working with huge files, I would like to be able to upload large file (up to 10Gb). In my Django code, I already upload the files as chunks using this code: tmpFile = NamedTemporaryFile('w', delete=False) try: with tmpFile: for chunk in inputFasta.chunks(): tmpFile.write(chunk.decode("utf-8")) open(tmpFile.name, 'r') fastaSequences = SeqIO.parse(tmpFile.name, 'fasta') finally: os.unlink(tmpFile.name) but it is still not running. On my IIS, I adjusted the maxAllowedContentLength and maxRequestEntityAllowed to their respective maximum (maxAllowedContentLength: 2147483648, maxRequestEntityAllowed: 4294967295). Is there any other adjustment I can do? Or do I need another programm to help me doing it? My program works fine with smaller sized files.
