How to change text of dropdown button after selecting dropdown item?
I'm having some trouble to getting my javascript to work, I was wondering if anyone could give me some guidance on where I can put the javascript code directly in my html file. Is this the correct way of doing it? This is how it looks right now on my screen. Thank you!! -
How do I retrieve a field from a Many-To-Many table?
I need to retrieve a value from a Many-To-Many query. Let's say I have 3 models: Toy, Part, and ToyParts ToyParts has a field called "part_no". I need to be able to get the value of this. class Toy(models.Model): parts = models.ManyToManyField(Part, through="ToyParts") class Part(models.Model): pass class ToyParts(model.Model): toy = models.ForeignKey(Toy, ...) part = models.ForeignKey(Part, ...) part_no = models.CharField(...) I've tried using: Toy.parts.all().first().part_no which obviously doesn't work as Part does not have a field called "part_no" I've also tried just simply using: ToyParts.objects.filter(toy=...,part=...) but that adds additional queries. How would I be able to get part_no without querying ToyParts directly? -
Django ModelFormSet clicking "Submit" saves form but does not update to database
Background: I'm building a personal dictionary web-application, and have a queryset of terms and definitions. In my web app, I have an edit page, where I want to show a ModelFormSet that allows the user to edit any/all entries, and delete them if needed - the form has a delete button for each row and a submit button to save changes to the form. The current issue is that when I click on a set to edit, the formset shows up correctly, and when I change a term and hit "Submit" the form updates to show the change. However, when I go back to my "View Set" page, the term hasn't been updated, which I assume means the change didn't go through to the actual database - the form itself was simply submitted. This is what I would like to currently fix, and I also want to make it so that the delete button deletes the entry. What I've Tried: I've gone through every StackOverflow question I could find relating to the topic, and various solutions were: add an instance parameter when passing in "request.POST", re-initialize the formset after saving, change the "action" url in the HTML page, etc., but … -
I need my Django get_absolute_url to do two different things
So I have a small issue with one of my models when I want to fire get_absolute_url. When someone create's an article on my site I would like it to return them to the 'under-review' page to tell them that there page is currently under review. But the issue is that my sitemap is showing that every article comes up as www.example.com/under-review/ instead of www.example.com/post/example-slug I would normally use return reverse('post-detail', kwargs={'slug': self.slug}) for that which fixes the problem. But then brings up the issue that when someone creates the article, it takes them straight to the page instead of the under-review page. Model: def get_absolute_url(self): # return reverse('post-detail', kwargs={'slug': self.slug}) return reverse('under-review') Ideally I would have it so when someone posts a post, it takes them to the under-review page up at the same time serves the return reverse('post-detail', kwargs={'slug': self.slug}) so it shows up correctly in my sitemap. Thanks. -
django url pattern problem 'NoReverseMatch'
I have 'url(r'^topics/(?P\d+)/$', views.topic, name='topic')' in urls.py but when I try to go to localhost:8000/topics/1 it tells me that it tried one pattern: 'topics/(?P\d+)/$' I would think it would be '*topics/(?P***d+)/$' I'm using a book called The Python Crash Course (1st edition)(ch. 18). This is a local server using Django 1.11 with Python. I've tried a lot of reformatting on the url pattern but I am new at this so I don't know what else to do. ... urlpatterns = [ url(r'^$', views.index, name='index'), # Show all topics. url(r'^topics/$', views.topics, name='topics'), # Detail page for a single topic. url(r'^topics/(?P<topic_id>\d+)/$', views.topic, name='topic'), ] I expected it to pop up with the correct page but it always says 'NoReverseMatch at /topics/01/' -
django-rest-framework, passing a foreign key field as url parameter for lookup
I am trying to search for all serial numbers with a specific sales_order(foreign key) field by providing the sales order as a url parameter to its viewset. I'm not sure why my queryset isn't being displayed by a GET request This is a new system I am developing, and as a django newbie I am having some trouble getting everything working the way I'd like it too. Currently, I have configured my routes so that 127.0.0.1:8000/api/serialWSales/ just displays all serial numbers, and I want to have 127.0.0.1:8000/api/serialWSales/(<sales_order>)/ to display only the serial numbers with the sales order number given. I was able to get and print the desired queryset based on the sales_order key, but am having difficulty displaying the queryset with a GET request. I am unsure why the queryset isn't being displayed and the "display: Not Found" exception is being given. Relevant models # Model for Sales table class Sale(models.Model): sales_order = models.CharField(max_length=70, blank=False) model = models.ForeignKey(Model, null=True, on_delete=models.SET_NULL, related_name='sales') quantity = models.IntegerField(blank=False, default=1) customer = models.ForeignKey(Customer, null=True, on_delete=models.SET_NULL, related_name='sales') sale_id = models.IntegerField(default=1, unique=True, primary_key=True) class Meta: unique_together = [['sales_order', 'model']] verbose_name = 'Sale' verbose_name_plural = 'Sales' db_table = 'tbl_sales' def __str__(self): return self.sales_order def save(self, *args, **kwargs): …
