Hi I have problem when trying to handle error message when sending post request with fetch JS to django rest, calling serializers.ValidationError, but further fetch doesn't handle this - in console I have an error message: general.js:26 POST http://127.0.0.1:8000/all/ 400 (Bad Request)

hello, just want to know steps to change default django admin login template to my own customize html page ...??

Would you help me with this situation, how to transfer in function "validate_date" parameter "date"?

There must be something to ur data

Validators simply accept a value of its field. So in your case it will be validate_date(datetime) and you will have to deal with this object in your function.

can you please tell what do you mean?

Hi everyone! We can validate data while creating model in two ways: 1) in ModelForm - using clean_fieldname 2) in Model itself (If there is some another useful method to validate data, pls, tell😅) So - what is the more widely used way to validate data?

I probably need to use the clean () method?

It is a wide topic. In short words - you should use Form.clean for a particular case and Model.clean for general. For example, you have a model Order and after a user submmited it, it will be processed by different groups of operators (to confirm, to find consisting items and so on) but you always want that model to check some of its fields.

SELECT name, STRING_AGG(description, ', ') FROM test JOIN ekwdesc ON ekwdesc.value = ANY(test.ekw) GROUP BY name Hi, How can I write a query like this using ORM?

Can anyone help me with django. I am having errors

Can anyone help me with django. I am having errors

!meta

I can send photos to explain

What does it means by TypeError: 'module' object not iterable

Not sure about that ANY, but I think that that STRING_AGG will be smt like: from django.db.models import F, Func Test.objects.annotate(description_agged=Func(F('description'), function='STRING_AGG'))

Thankyou for the response...My problem is similar to this question: https://stackoverflow.com/questions/30816763/postgresql-integer-array-value-join-to-integer-in-other-table-with-desc-string . The solution query given in this question works correctly. But I want to write that same query using Django ORM. Is that possible using orm?

I'm not orm-guru. And I'm agreed that if smt hard to make in it - simply use raw sql

Heard of pastebin?

No. What is it?

No. What is it?

Cuz it'll be tough to debug with half ass resource like your traceback

Also I am following a tutorial. Link: https://djangocentral.com/building-a-blog-application-with-django/

Dude, you're doing something wrong probably

Ya I know m doing something wrong. But unable to find my mistake. I followed tutorial line by line

Something you messed up there

Yeah paste both and I'll have a better idea!

Make your project a git repo, 1. You get to learn vcs which is kinda important 2. You reap benefits of vcs. 3. Easy to ask what's wrong 4. It's a win win, so profit?

Posted both urls. Also, I don't know what is all this. I know about github.com where people post their projects

You're using windows, right? Can you open a command prompt shell in your project directory and run a tree command?

Be like a postage stamp — stick to one thing until you get there. (J. Billings)

I'm sorry, tree doesn't list the files under a directory?

Any suggested place? What exactly is this vsc git etc?
