Django objects.all() not updating without server restart [closed]
django objects.all() only seems to be updating after server restart. For example, I would make a category called 'Education' and it shows up on the admin site, but when I'm using in the form, it will not show up unless I restart the live server. forms.py: def tuplelistmaker(list): output = [] for x in list: newtuple = (x.pk, x) output.append(newtuple) print(output) return output class PostForm(forms.Form): title = forms.CharField(max_length=100, label='Post Title') short_description = forms.CharField(widget=forms.Textarea(attrs={"rows":3, "cols":100})) content = forms.CharField(widget=CKEditorWidget()) status = forms.NullBooleanField(label='Ready to Publish?') image = forms.ImageField(label='Select a cover image:') captioned_image = forms.ImageField(label='Select a captionable image:') caption = forms.CharField(max_length=200) category = forms.ChoiceField(choices = tuplelistmaker(list(PostCategory.objects.all()))) embed = forms.CharField(widget=forms.Textarea(attrs={"rows":3, "cols":100})) tags = forms.CharField(widget=forms.Textarea(attrs = {"rows":1, "cols":150})) models.py: class PostCategory(models.Model): category = models.CharField(max_length=100) categorySlug = models.SlugField(max_length=100) def __str__(self): return self.category class Post(models.Model): title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=200, unique=True) author = models.ForeignKey(User, on_delete=models.CASCADE, related_name= 'blog_posts') short_description = models.TextField() updated_on = models.DateTimeField(auto_now=True) content = RichTextField() created_on = models.DateTimeField(auto_now=True) status = models.IntegerField(choices=Status, default=0) cover_image = models.ImageField(upload_to = 'coverimages', null =True, blank = True) captioned_image = models.ImageField(upload_to = 'captionedimages', null=True, blank = True) caption = models.CharField(max_length=300) featured = models.IntegerField(choices=Featured, default=1) category = models.ForeignKey(PostCategory, on_delete=models.CASCADE, null=True, blank=True) embedded_code = models.TextField(blank=True, null=True, default='null') tags = models.TextField(blank=True, null=True) class Meta: … -

Django - Change client encoding from WIN1252 to UTF8
So I have my Django application deployed on a Heroku server and when I try to query for Post I get this.

How to import .py file from django's static dir from within a brython.html template?
Like the title says, I'm running a django webapp using Brython (NOT Javascript), hosted on Heroku, and would like to import a .py file located in the static folder. I am able to import and display the contents of the .py file, but when I try to import it, the webpage remains blank (white screen) with no errors (status 200). My debugging is possibly not developed enough to catch the error, but usually I will get a traceback when I have errors as debugging is on. So, the status 200 and blank white screen are important, I believe. Although debugging is not the subject of my post, any short insights into why I'm getting this result would be of interest. Here's the code I'm trying in the html template with a couple failing examples, and one suboptimal solution that does run mostly as hoped: <body onload="brython()"> <script type="text/python"> from browser import document, html # This line works and displays the contents of the .py file in browser, # used to rule out my staticfile options in settings document <= html.H1( open("{% static 'my_py_script.py' %}").read(), Id="main") # Here is one method I've tried that causes the browser to remain blank on … -
Django address city-district-neighbourhood choisefield
I have been trying to build a form in which can be chosen address city-district and neighborhood data according to city-district relation. For example when the user choose city then I want to see districts of the city. I am new at Django and coding and I've been searching and trying for a couple days.
