How to access database table with primary key in Django SQLite3 database
In my Django app, I'm adding a search feature that will search the posts database and return matching results.

django validating a field even when a depending field is empty
I am trying to validate two depending fields such that, if a checkbox is checked, then validate the URL field, but if the checkbox is not checked, do not validate the URL field. Using clean() I have a code that looks like this: models.py class MyModel(models.Model): chkbk = MultiSelectField(max_length=15, choices=choices.SOME_CHOICES, blank=True, null=True) url_field = models.URLField(max_length=200, blank=True, null=True) form.py def clean(self): cleaned_data = super().clean() chkbk = cleaned_data.get('chkbk') url_field = cleaned_data.get('url_field') if chkbk and url_field is None: self.add_error('chkbk', ValidationError("Fix this error")) The logic works if the user checks box and submit a valid URL the user checks box and leaves url field empty, error message the user unchecks box and leaves url field empty But, when the user unchecks the box but have invalid url in the url field, the for does not submit, because regardless of the validation checks, the url field will still try to submit to the database, which is an expected behaviour. Is there a way to not validate the URL field if checkbox is unchecked or set the value of that field to empty/null/None in clean just before submitting the form so validation on the url field can pass if the checkbox it depends on is not … -

Django Pyrebase retrieving from firebase using infinite scroll

Why Django cannot extends my form.html contact page and returns a TemplateSyntaxError or an Exception Thrown?
I'm trying to build a contact page ("/contact-us/") as a modular app instead of the similar already working contact page ("/contact/") located in the "/app/" directory. The former is failing, returning either Exception Thrown or TemplateSyntaxError while trying to {% extends %} the form.html with its base.html.

How to include the thumbnail image with using TabularInline admin model?
What I am trying to do I would like to include thumbnail in PhotoInline and could be shown into ProductAdmin. What I have done I made two admin model which are ProductAdmin and PhotoInline. PhotoInline model is a separate admin model that only contains information of photos of products, which is to be connected to ProductAdmin. Inside of PhotoInline, I included custom admin function called product_thumbnail and tried to include list_display admin option of ProductAdmin. Here are my codes: class PhotoInline(admin.TabularInline): ''' PhotoAdmin Definition ''' model = models.Photo fieldsets = ( ( None, { 'fields': ('caption', 'file',) } ), ) extra = 0 and then ProductAdmin admin model looks as follows: @admin.register(models.Product) class ProductAdmin(admin.ModelAdmin): ''' ProductAdmin Definition ''' inlines = [ PhotoInline, ] list_display = ( 'product_name', 'product_price', 'product_color', 'product_size', 'product_category', 'is_onsale', 'is_newarrival', 'is_preorder', ) list_filter = ( 'is_onsale', 'is_newarrival', 'is_preorder', ) ordering = ('product_name', 'product_price', 'product_category') search_fields = [ 'product_name', 'product_category' ] Error that I got <class 'products.admin.ProductAdmin'>: (admin.E108) The value of 'list_display[8]' refers to 'product_thumbnail', which is not a callable, an attribute of 'ProductAdmin', or an attribute or method on 'products.Product'.
