JS TypeError when not waiting for the document to be ready [duplicate]
I am using Django and running a basic JS command for testing and manage to make it work if I wrap it such that the command start only after the whole document is ready or if I wrap the command between <script> tag inside the html directly, but not if I use a JS block tag and call the JS command. Why ? In more detail, say I have an html template and inside that template I have the js tag: {% block js %} <script src="{% static 'app/js/basic.js' %}"></script> {% endblock %} inside basic.js, this works: document.addEventListener('DOMContentLoaded', function(){ document.getElementById('js-table').style.height = "50px"; }); but this doesn't: document.getElementById('js-table').style.height = "50px"; and returns TypeError: document.getElementById(...) is null if I include a console.log, it prints correctly so the call to basic.js file works if I add the script below directly in the html it works: <script> document.getElementById('js-table').style.height = "50px"; </script> -

Best way to access reverse relation's attributes
I have these three models : MenuItem, Subs and Pizzas Both Subs and Pizzas have a foreign relation on MenuItem, for example : menuItem = models.ForeignKey('MenuItem', related_name='pizza', on_delete=models.CASCADE) Moreover, both Subs and Pizzas have a @property price() property. I would like to access this price property from the MenuItem, in order to be able to compute the price of an order. What would be the best way to implement this ? I have thought about defining a price() property in MenuItem, but then how do I access the reverse relation in order to retrieve the price, considering there may be multiple reverse relations ? Do I need to check every possible reverse relations, to find one that is not Null, and then access the price ? Thank you -

how do i get specific field in a form?
So what I'm trying to do is, I get long text from a user via the modelform I've created. Then in my models, I want to save the first sentence of the text. In order to do this, I believe I have to get the data(long text) from the form, and use a function to leave nothing but the first sentence. But I have as a beginner in Django, I have no idea on how to get an individual field from a form. So this is my codes: models.py class InputArticle(models.Model): objects = models.Manager() authuser = models.ForeignKey(User, on_delete=models.CASCADE, related_name = 'dansang', null=True, default=None) title = models.CharField(max_length=100) contents = models.TextField(max_length=100000) first_sentence = models.CharField(max_length=100) def __str__(self): return self.title forms.py class InputArticleForm(forms.ModelForm): class Meta: model=InputArticle fields=['title', 'contents'] I want to later display the title, contents, and first sentence in a separate page.

Python Django - How to Pass HTTPS URL as function parameter in manage.py shell

django template custom filter
I'm fairly new to django and I believe this is django template related question. I've got a project template where there is a certain value, namely {{ tenant_name }} which tells the tenant name. I've used for loop to find out all tenant names which works fine. How ever, all of the tenants have units under them and when I try to display units per tenant with for loop it loops all units to all tenants which is not what I want to do. note: self.tenant can't be used in this case as the user doesn't have a tenant yet. I've tried to solve this using custom filter, by registering it and loading it to the template and then filtering like so: {{ tenant_name|filter_units }}, however this doesn't seem to work for some reason. My question is this: is it possible to extract tenant_name from the template to the filter, use that value in the filter to search for units and return it back to the template? If so, could you possibly show me how? If it is not possible, is there a better way to accomplish this? Thanks in advance. -
Django: Error in creating custom fields in Django
I tried this on my model: class NameField(models.CharField): def __init__(self, *args, **kwargs): super(NameField, self).__init__(*args, **kwargs) def get_prep_value(self, value): return str(value).lower() class City(models.Model): state = models.ForeignKey('State', on_delete=models.SET_NULL, null=True) name_regex = RegexValidator(regex=r'^[a-zA-Z]+$', message="Name should only consist of characters") name = models.NameField(validators=[name_regex], max_length=100) postalcode = models.IntegerField(unique=True) class Meta: unique_together = ["state", "name"] Now I am getting error as: AttributeError: module 'django.db.models' has no attribute 'NameField' How to resolve this error?
