Django update form: does not conform to the required format, "yyyy-MM-dd"
I am using Django in the backend to save a date that the user inputs. Then later, I want to allow the user to update that date input by bringing them to a new page, showing them the old date input, and allowing them to update it. I am using a datepicker input field for the frontend to easily allow the user to pick a date. After I input my date, and I go to the update page to change it, the datepicker input field on the update page is empty every time. In the console I see The specified value "Jul. 4, 1776" does not conform to the required format, "yyyy-MM-dd". I think the problem is that when I am retrieving the date from the database it is coming in as a different format than the forntend wants it. The date is coming from the backend as Jul. 4, 1776 format and the frontend form needs it in 1776-07-04. I was wondering how I can fix this so both frontend and backend are happy, and the old date inputted by the user is shown in the update page datepicker input field -

How to display the fields of a foreign key in django admin form?
What I want to do is, say I have a model Person, I want to display the contact number of the Person anywhere(I mean I don't care where to place it, as long as someone can see it but preferably on the top so it's easy to find) in the Form after selecting it on the auto complete and when viewing a record. I was able to show the contact number when selecting from the auto complete using a Form, a rest_api and js. But when the fk field is read_only, I want to still get the Person and display the contact number as well. When the Person fk is read_only, I will use the Person of the person logged in, which I can already get in get_form, but I can't seem to set the Person to it's field. I already tried multiple ways of doing this. Using get_form and set the form['field'] for it, setting initial when declaring the Form, make a view for my PersonForm in views.py, using widget but still can't seem to make it work. And unfortunately it seems like no one has made this scenario before so I didn't find any definitive answer to my … -

Is there a way to pass URL template tag from database to template in Django?
I apologize if my question is poorly worded. Basically, I am making a database of fictional characters and in the database, I have a biography of the character. I would like to link to other characters using the {% url 'viewname' otherchar.slug %} method. However, all I get back from the database is literally that line of code. I understand it may not be possible, but is there a way to get Django to see that line and turn it into an absolute URL like it would if I manually added the URL tag into the page? Something to add - I am using TinyMCE so the content in the database is being saved with HTML - I want to be able to save external links, subheadings, and whatnot, which is why I chose to use TinyMCE and its HTML field. models.py class Character(models.Model): name = models.CharField(max_length = 255) faction = models.IntegerField(default = 0) rankIMG = models.ImageField(upload_to = 'rankIMG/', blank = True) department = models.IntegerField(default = 0) content = HTMLField() slug = models.SlugField() views.py class CharacterFull(DetailView): model = Character context_object_name = 'character' def get_context_data(self, **kwargs): context = super(CharacterFull, self).get_context_data(**kwargs) context['factionDict'] = charFaction context['deptDict'] = charDepartment return context urls.py app_name = … -
Retrieve Access/Refresh token with username/password from Django REST API
I am trying to build an application on Google AppScript that should communicate with a third-party API. This API uses Django REST Framework and JWT. I have a username and password to access domain/api/token, login and get the access and refresh tokens. I can do this manually but I would like to implement some sort of a login on my application side that will get a new access/refresh (if needed) token from the API so it can start fetching data from the service. My question is, how can I structure the POST request to retrieve the access/refresh token pairs so I can continue with the next requests? This is what I'm trying to do: var formData = { 'async': true, 'crossDomain': true, 'method': 'POST', 'headers': { 'Content-Type': 'application/json', 'username': 'user', 'password': 'secretpassword' }, 'muteHttpExceptions': true } var url = 'domain/api/token' var res = UrlFetchApp.fetch(url, formData); -
Fetching results from a method in Django
My Django app ('crisismode') has two models : Events and Actions I would like to display events and actions related to these events. For each event, I only want to display active actions, so I used a method (activactions).

Why isn't my image loaded/fetched from AWS RDS in my React application?
So I have my Django Rest Framework deployed with AWS EC2. I also have RDS instance for saving images. Then I have a React application deployed that fetches some objects(including the images) from DRF. Now when I load the page, all the other fields(?) of each object are loaded but the image. I see 404 Not Found error, and have no idea what is going on. I have console.loged and saw the object myself, and the url of the image is just fine. http://ec2-some-address.ap-northeast-2.compute.amazonaws.com/media/None/myimage.jpg. the media/None/ directory is as expected. Any idea? Thanks a lot in advance :) -

Django Find custom user with the same value of JSONfield
I have a django application, where I use custom user model. Model has a JSONfield, which represents which programming languages do this user use.

implement dynamic database models for messenger web app django
i want to create a messenger webapp in django in which a sql table will be created which will only store the conversation of two user . the naive approach is to create a table for messages which will store info like id,message_text,sender,reciever etc. but in case of large user this will not be efficient. if we allot a conversation between two user in a single table then it will reduce the searching time. i dont know how to implement dynamic models .

Want to first save user profile data and then automatically create user
This application is for a school where the admin(through django admin) can upload the student's data and based on that, a user is created ( username is ID and password is dd/mm/yy).Basically removing the need for all the students to register themselves on the platform. I've seen videos where signals are used to create profile from user using post_save() but to create user from profile I can't use that since profile editing is also allowed which will trigger post_save() and try to create a user, even though one already exists for that profile. Any help will be appreciated. Thank you -
How to track monthly subscription usage of user in django?
I have the scenario where I have three models: Subscription Model User Model (Has Subscription Model ForeignKey) Match Model (Has User Model ForeignKey) Users can choose to sign up for 6 month/ 12 month/ 18 month subscriptions where they can have a maximum of 10 matches PER MONTH. Users may start the subscription on any given date of the month. My question is how do I track how many matches are assigned to the user in a given month(with the first date of the month being the date he signed up on)? How do I reset the number of matches back to 10 after every month finishes? -
Django HTML page is showing template code for form as text
I'm pretty new to Django (technically this is written in Django-Mako-Plus), and I'm trying to display a form on an HTML page, but it is displaying the template code as text and I can't figure out why. I've set up my form in forms.py: class FilterForm(forms.Form): def init(self): self.fields['keywords'] = forms.CharField(label='Keywords') self.fields['hours'] = forms.CharField(label='Training Hours') self.fields['instructor'] = forms.CharField(label='Instructor') self.fields['subject'] = forms.CharField(label='Course Subject') self.fields['agegroup'] = forms.CharField(label='Target Age Group') I've added the form to my context variable in the view: from django import forms from .forms import FilterForm @view_function def process_request(request, cat_id:int = None, pnum:int = 1): currentDate = datetime.today() currentYear = currentDate.year #allcourses = hmod.Courses.objects.all() allcourses = hmod.Courses.objects.only("courseid", "coursetitle", "coursephoto", "coursedescription") form = FilterForm() context = { # sent to index.html: 'current_year': currentYear, 'allcourses': allcourses, 'form': form, } return request.dmp.render('courselist.html', context) And I've tried to display the form on the page in the template. <form action="/your-name/" method="post"> {% csrf_token %} {{ form.as_p }} <input type="submit" value="Submit"> </form> The problem is, when I go to the page, instead of showing the form, {% csrf_token %} and {{ form.as_p }} show up as text on the page.

How to add exception to a dictionary if the result is useless for my data?
So I have this code to get the id of a person and check if the person exists in a database. The code works but I forgot to add an exception for people who exist but their id is not a "useful" one. I tried adding an exception to my code that says: except cuit == "CUIL": print("it's not a cuit") But this is ignored and I get the data anyway even though I don't want it. So what's a better way of doing it? The info is in response["persona"]["tipoClave"] This gives two results: "CUIL" (not useful) and "CUIT" (useful). So how do I prevent the useless ids to be passed as useful?

How to change the template of password-reset-email properly Django
This line of code is responsible from sending an email which contains a password reset link. path('accounts/password-reset/', auth_views.PasswordResetView.as_view(), name='password_reset'), However the email looks completely dull and it is difficult to distinguish important parts while reading. To attract the attention of the user and direct them better I would like to add style to this body of email. It is possible to add custom template to the email by these lines: ... path('accounts/', include('django.contrib.auth.urls')), path('accounts/password-reset/', auth_views.PasswordResetView.as_view(html_email_template_name='registration/password_reset_email.html'), name='password_reset'), ... The thing is the reset-link inside the email consists of a uidb64 value and a token, such as: localhost:8000/password-reset/calculated_uidb64/calculated_token What is the proper way to pass these values to the custom template of password_reset_email.html?
