SweetAlert in Django not appeared No JavaScript reporting
I started learning Django by following a YouTube tutorial. Everything seems to be fine, the only thing that is not working is a short script at the end of the template, which is unfortunately not working: <!-- MESSAGESS FROM BACKEND --> {% for messagge in messagges %} {% if messagge.tags == 'success' %} <script src="//cdn.jsdelivr.net/npm/sweetalert2@11"></script> <script> var m = "{{ messagge }}"; swal("Perfect!", m, "success"); </script> {% endif %} {% endfor %} </div> <!-- END OF CONTAINER DIV --> {% endblock content %} -

Best way to store and display warning messages using Django?
I'm looking for the best and easiest way to store and to display warning messages shown to the user at the creation or at the update of instances of some models. I want users to tick a box (or to click twice) to be 100% sure that they are aware of what they are doing. I want the warnings to be saved in the database if and only if they have been read. My current solution on the client side Currently, on the front-end side, this is how it looks like: But I'm not totally satisfied with this homemade interface because it still lacks some JS functions to update/hide the warning(s) when the input changes, without waiting for the user to resubmit the form. I guess I could write them or draft a dedicated validation page but I wonder if there isn't a library or a framework that could partially do the job. My current solution on the server side For now, on the back-end side, I use a parent abstract class with a custom JSONField keeping track of that information: class AbstractBase(models.Model): warnings: dict = models.JSONField( default=dict, validators=[JSONSchemaValidator(limit_value=WARNINGS_JSON_SCHEMA)], ... ) ... Along with these few lines of code, I … -
Constantly problems with Python: Python was not found, can't open file…,

What exactly does X_FRAME_OPTIONS = 'SAMEORIGIN'?
I created a site in Django that I deployed on heroku. I am looking to display this site in an iframe in an html page present on my localhost. Which is not done, because the default value of X_FRAME_OPTIONS is DENY which don't autorize this. When I search the internet, I am asked to replace the value DENY with the value SAMEORIGIN. I learned about the official Django documentation from this passage: Modern browsers respect the X-Frame-Options HTTP header which indicates whether a resource is allowed to load inside a frame or iframe. If the response contains the header with a value of SAMEORIGINthen the browser will only load the resource in a frame if the request comes from the same site. What I don't understand is that I'm looking to load a site that's on the web from a web page that has an iframe in it and I'm wondering if they mean by this passage in the doc that the site can be loaded by a web page present on the computer that deployed it or can one of the web pages present on the deployed site load it in an iframe, something that I do not understand … -

Model constraint on checking existing relationship between two fields
I'm writing a Django app and I want Users to be able to review Courses. The Users have to select the Professor they are reviewing when creating a Review, because multiple Professor can teach that single Course. I created a Taught table that keeps the relations between Professors and Courses. How do I enforce that when I'm adding a review, I will only be shown in the dropdown of professors, the professors which have an existing relationship with that course (only the professors which have taught the course). class Professor(models.Model): name = models.CharField() class Course(models.Model): name = models.CharField(max_length=200) professor = models.ManyToManyField(Professor, through="Teaches", related_name='taughtBy') class Teaches(models.Model): course = models.ForeignKey(Course,on_delete=models.CASCADE,related_name="reviews_course") professor=models.ForeignKey(Professor,on_delete=models.CASCADE,related_name="reviews_professor") class Review(models.Model): author = models.ForeignKey(User,on_delete=models.CASCADE,related_name="is_author") course = models.ForeignKey(Course,on_delete=models.CASCADE,related_name="reviews_course") professor = <<<<How do I enforce that professor and course have to have an existing relationship in Teaches?>>>> -
Setting css class to field in form depending of it's type
I want to manually render login and signup forms in Django.

For example: Field_1 has type text, so we apply css-class-1 to it Field_2 has a checkbox type, so we apply css-class-2 to it -

How to render ValidationError in Django Template?
I am new in Django, and I ask community help. Now I I'm working on user registration and I want to do password validation: if passwords are not repeated, a message appears below the bottom field. As far as I understand, {{ form.errors }} must be used to render the error text specified in ValidationError , but when this error occurs, its text is not displayed on the page.
