Hi guys, can someone help me with a doubt please? I have a lot of filters, and i need verify if a context exists in a queryset, if the value is positive i have return the filter How can i do this?

is it possible to send 3 querysets using class-based views? I remember trying to use get_query_set once to return 3 queryset variables, but it did not work

hi, i made a migration i added a field to my table, it went read_only and i don't understand why

is not working

can u access psql?

nothing appears on the page, everything is ready to iterate the querysets.

can u access psql?

You really need some sleep 😴, where is the = sign

the schema is not updated :/

So there is no new column ?

this is really strange, but is this your first migration update? maybe user alter permission or something ? just throwing some guesses

still decreases lines by changing queryset by model = Post

Somebody please look into it.

Hi Django friends, only quick question, I have mp4 file hosted on foreign server, is it possible to offer download dialog to user despite of I don’t host that file? Thank you in advance.

What am I doing wrong here? before everything was ok and now is no longer working. I was counting all posts in the template with {{posts.objects.all.count}} and is now no longer returning the total number of posts. I can only use | lenght to count but only returns the current posts of the page.

Can someone have a look at this for me: https://www.django-rest-framework.org/api-guide/filtering/#api-guide Look at the code example over (the text): "http://example.com/api/products?category=clothing&in_stock=True" <— dummy (on the page link over !) A link like this would meen that in the field "category"' the PK would be clothing? In my case i have a foreign key in my "?my_field=foreign_key_id" which is the PK of my foreign key? This is how i got this to work I just want to understand. btw, my serializer is nested, could that be the difference My point: My link = '?type=5&child_category=3' not 'installprices/?type=sometext&child_category=sometext' Am i getting this right ?

Clothing is not the pk, is just a filter being applied. Take a look here, theres an example and explaination about single object lookups https://www.django-rest-framework.org/api-guide/filtering/#filtering-and-object-lookups

Hints on error messages clearly says what you need to do

Yes i get that, but where does the "clothing" come from? and how can i decide to use model.name instead of model.id like mine is automatically using.

Hi, how can I update what shows in a field in django admin according to the previous field? For example: If I click in X in field 1, it will show W, Y, Z in field 2 If I click in P in field 1, it will show Q, R, S in field 2

Is it possible for A model to have choices based on a foreign key or simuler, say you choose CAR then you also get the choices of HP, if you choose PEN you get the choice of COLOR.

{{ posts.count }}

not work

Not really sure but I think this should be defined in the serializer with https://www.django-rest-framework.org/api-guide/relations/#primarykeyrelatedfield and using pk_field

The count problem still persists, but when I pass it through get_context_data, it works normally ... But then paging and stuff stop working. Basically my blog views are complete for now, any refactoring tip or anything? https://pastebin.com/7yWn2vLa Note: I use tags in all views because I want to display all the tags in the dropdown that stays in the blog base file, so in any view I need to iterate over all tags. I thought it better to do this than to type all tags in html.

Hello guys, I don't know anything about Django. But have an idea about python. I want to learn Django from beginning, please provide some basic course or tutorial to touch the concept of Django. Thank you. 🙂🙂🙂

thank you batman

hi ,im modifying some shit in the django admin but __init__ doesn't execute :( #admin.py class SolarPlantForm(forms.ModelForm): foo_field = forms.CharField(max_length=20,required=False) class Meta: model = PowerPlant fields = ['__all__', 'foo_field'] def __init__(self, *args, **kwargs): print("hey") class PowerPlantAdmin(admin.ModelAdmin): model = PowerPlant form = SolarPlantForm admin.site.register(PowerPlant, PowerPlantAdmin)

Seems that __init__ is defined inside of meta

Meta Warning: I am curently working on a project with a php developer. He makes the front end and I make the API. I've been thinking to learn another language for a while now and was wondering if you think this is a good combination. So far I have not really seen anything in the frontend you can not do with python. Id like to hear from someone with experience from both worlds.

frontend ? you mean backend right ?
