how to use csrf token in Django integrated with vuejs using Django webpack loader?
I am using Vuejs as frontend and Django rest framework as backend, I have some confusions how to use csrf token, my question has 2 part, first I write my configurations. first as Django documentation stated, "If your view is not rendering a template containing the csrf_token template tag, Django might not set the CSRF token cookie. This is common in cases where forms are dynamically added to the page. To address this case, Django provides a view decorator which forces setting of the cookie: ensure_csrf_cookie()", so this is my view that renders the page which loads webpack bundles. @ensure_csrf_cookie def main_view(request): return render(request, 'index.html') and again as Django documentation I used below configuration to send csrf token along with Axios request. function getCookie(name) { let cookieValue = null; if (document.cookie && document.cookie !== '') { const cookies = document.cookie.split(';'); for (let i = 0; i < cookies.length; i++) { const cookie = cookies[i].trim(); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) === (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } const csrftoken = getCookie('csrftoken'); //axios request async createFromCSV(token, data) { const options = … -

Django raw query gives none value
I have a questionnaire. I like to get the value of a row with raw query but when I loop through in my HTML file it gives me just the first value but the rest 11 gives me none so my addition oft the values also gives me none. I can't understand what am I doing wrong. I made this operation many before on the same way and worked great. I have 12 questions that I made with html input (not Django forms) for certain reasons, but it works well and it posts the values to the database where I have all the positive and negative values. models.py class Vezetoi(models.Model): def __str__(self): return str(self.user_name) user_name = models.ForeignKey(User, on_delete=models.CASCADE, default=1) vezetoi_v01 = models.IntegerField( null=True) vezetoi_v02 = models.IntegerField( null=True) vezetoi_v03 = models.IntegerField( null=True) vezetoi_v04 = models.IntegerField( null=True) vezetoi_v05 = models.IntegerField( null=True) vezetoi_v06 = models.IntegerField( null=True) vezetoi_v07 = models.IntegerField( null=True) vezetoi_v08 = models.IntegerField( null=True) vezetoi_v09 = models.IntegerField( null=True) vezetoi_v10 = models.IntegerField( null=True) vezetoi_v11 = models.IntegerField( null=True) vezetoi_v12 = models.IntegerField( null=True) forms.py class VezetoiForm(forms.ModelForm): class Meta: model = Vezetoi fields = ['vezetoi_v01', 'vezetoi_v02', 'vezetoi_v03', 'vezetoi_v04', 'vezetoi_v05', 'vezetoi_v06', 'vezetoi_v07', 'vezetoi_v08', 'vezetoi_v09', 'vezetoi_v10', 'vezetoi_v11', 'vezetoi_v12' ] views.py - I didn't copied some parts here that are … -

Getting a RelatedObjectDoesNotExist error in Django, would like to make new Object if one does not exist
If I get this RelatedObjectDoesNotExist error, and I want to work around it, I would like to make some "if" statement that produces those related objects in the database so they can exist if they didn't before. In my model: user = models.OneToOneField( User, null=True, on_delete=models.CASCADE) var_1 = models.PositiveIntegerField(validators=[MaxValueValidator( 2000), MinValueValidator(50)], null=True, blank=False) var_2 = models.PositiveIntegerField(validators=[MaxValueValidator( 2000), MinValueValidator(50)], null=True, blank=False) var_3 = models.PositiveIntegerField(null=True, blank=False) var_4 = models.CharField(max_length=254, null=True, blank=True) var_5 = models.CharField(max_length=254, null=True, blank=True) So, the user does exist, but the var_1 - 5 do not. But, they will need those eventually (especially to view the page I am accessing). Therefore, if they access that page, I just want to create those variables in their database attached to their username. I hope this is enough information for this. I am very new to Django and I am finding all the different models/views etc a little confusing. -

Django + React how many requests are too many?
I am creating an app with react frontend and django rest framework backend. It will basically be a fancy form with which the user can create an "order" of many products. The backend has a database of around 10000 products which have the following formating: { "id": 1, "code": "1400", "height": 60, "width": 50 } Many of the products share the same code. There are roughly 20 unique code values equally divided among the whole. So roughly 500 products with each code. The frontend part of the app has a series of dependent dropdown lists that the user can use to specify a combination of code, height and width. The requirement is of course that the desired combination must be a valid one, meaning, it must represent an item that exists in the database. So if for example the user choses the code 1400 from the first dropdown list, the possible "select" values from the second dropdown list must be height values that correspond to items with the code 1400. The frontend uses axios get requests to fetch the data from the backend and then does the required calculations. The problem is, regarding design. How should I balance the amount … -

checkboxes added dynamically with django
I am using formsets so add button adds the form but I want to remove them after the delete checkbox has been checked (where i need help), I dont understand much javascript. Here might be the answer but it does not work for me: Can't understand why this error(Uncaught TypeError: $(...).is(...).each is not a function) got on? when I try this code: $("input[class='remove-form']").click(function(){ var n = $( "input[type='checkbox']:checked" ).length; console.log('n here',n) $("input[type='checkbox']:checked").each(function(){ // $(this).parents('.form-row').remove(); console.log('removed'); }) }) only the first checkbox works(which wasn't added dynamically)(or in log case shows the number of boxes checked). The dynamically created checkboxes don't just show any response. The Form which will be appended: <div id="items-form-container" style="display: none;"> .... <div class="col-2"> <label>Delete</label> </div> <div class="col-4"> <div class="input-group"> <input type="checkbox" name="quizz_question-__prefix__-DELETE" class="remove-form" id="id_quizz_question-__prefix__-DELETE"> </div> </div> In short the dynamically added checkboxes doesn't work in my ajax function.Please HElp. -
