CSRF_token is not valid in djnango Ajax multiple request from same page
I'm trying to perform a OTP-based login in my project. So I have a form with email and password field in the login form and when I submit it through AJAX request I check for the email and password in the database, if the values are correct then I will send an OTP through email and display a new OTP field on the same page for Entering the OTP for verifications. Till now everything is working fine but after entering the OTP when I try to re-submit the form, I got an error csrf_token is not valid. As far as I know csrf_token is only generated on page refresh or page load but in my case the first csrf_token that was generated on page load was used in first post request. So now how can I send the second post request with same csrf_token or can I generate the new csrf_token . Code snippets are as follows; <form id="loginForm" method="post" action="send_otp"> <div class="col-12"> <label class="text-16 lh-1 fw-500 text-dark-1 mb-10">Email</label> <input id="email" type="text" name="email" placeholder="Name"> </div> <div class="col-12"> <label class="text-16 lh-1 fw-500 text-dark-1 mb-10">Password</label> <input id="password" type="password" name="password" placeholder="Password"> </div> <div id="otp_field" class="col-12"> </div> <div class="col-12"> <button type="submit" name="submit" id="send_otp" class="button … -

Django Rest Framwork validate ListSerializer field from data received by form-data request
I am using Django and DRF to handle a restful backend. A request is sent that contains some fields and data (attached images). The request is received by a DRF serializer. I sent the request using form-data (via Postman). I received all fields and images properly except for a ListSerializer. The field is: class ListSerializerClass(serializers.Serializer): field_1 = serializers.IntegerField() field_2 = serializers.ListField(child=serializers.IntegerField(), min_length=1) class MainSerializerClass(serializers.Serializer): list_serialized_field = InputOfficeTaskTypeMap(many=True) normal_field = serializers.CharField(max_length=50) normal_field = serializers.CharField(max_length=50) Using Postman I send a list_serialized_field as a json: {"code": 123, "list_serialized_field": [{"field_1": 1, "field_2": [1,2]}, {"field_1": 2, "field_2": [2]}] Unfortunately, I could not received validated list_serialized_field and after calling serializer.is_valid, I got error that "list_serialized_field" is required. Is there any way to send json data and files in one request and validate them? P.S: I know that I can send form-data like below: list_serialized_field[0]field_2[0] but I want to send them in JSON format. -

Trying to connect Django to MySQL. Connection error when migrating
I've been working for several weeks on Django. So far I have made 2 small projects. Now I tried to connect Django to the MySQL database. First, I started a new project. Then made a new app and updated the app in settings.py After that changed the database in the same file settings.py with my settings, Made a small model, Installed all the necessary aps, MySQLclient etc, Made the first migration successfully with 'Makemigration' So far so good! Next, I tried to make the second migration, as in the instructions. Then the error message appears: 'error 111, can't connect to database' Made some changes in the settings file, including SQL mode 'strict trans tables'. Now it shows me the error: Can't connect to local MySQL server through socket ... Missing file .sock. I looked up the directory and there was no such file. In the my.conf file the file is different!!! And exists! What is going on and what to do? -
