but WHY?

ok, i know it will work, but i thought it will work in shell too, at orm level

def get_default(self): """ Returns the default value for this field. """ if self.has_default(): if callable(self.default): return self.default() return force_unicode(self.default, strings_only=True) if (not self.empty_strings_allowed or (self.null and not connection.features.interprets_empty_strings_as_nulls)): return None return "" this is what Django does under the hood so no exception should be raised

wow i just want to paste same code

thanks @pyflare , @LuchoUY

From docs Note that full_clean() will not be called automatically when you call your model’s save()method. You’ll need to call it manually when you want to run one-step model validation for your own manually created models

Migrations for 'baseapp': baseapp/migrations/0002_auto_20190402_0711.py - Alter field name on author - Alter field title on book all migrations is OK, and i still getting authors with blank names. looks like I really need validators. thanks

this is not a bad idea btw, you can create your own model field that reject blank

so why do i even need django?

what do you mean?

i mean, if i need to write a model field that rejects blank values by myself. haha, just wondering

Just do not use model.objects.create Create an instance of your models and call full_clean method before calling save method. I experienced the same issue in 1.11 and full_clean do the job.

all right, I got it, thanks =) Django Tutorial is disappointing

Django is like strong vodka. Makes your pains easier, but simple stuff turns hard (like walk drunked)

mmm not completely agree with "simple stuff turns hard" but funny thought 😂

I like DJango. It makes web development pretty simple and fast, but you should to know what is it doing behind the scenes.

I think something looks hard just because lots of people wanna use Django without having a good knowledge of Python but if u used Django with a strong Python knowledge, especially OOP , you will find what framework offers to you easier obv it's just my pov

I'm agree! But it has these "details" like full_clean to force validation in new model's instances to avoid blank values, etc. Any way, I was joking about DJango and vodka... it's not personal haha

Does anybody have the VPS?

I want to set value of a field in a model using another field like this: (don't ask about why you do this, this is just a simple example) created = models.DateTimeField(auto_add_now=True) created_str = models.CharField(max_length=50) I want something like this: created_str = models.CharField(max_length=50, default=str(created)

well, it has to be asked... why? because... why do you want to do that if you already have the value in one field? nvm... you can override save() and do things there IG

How to initialize object and make accessible everywhere in project/app directory

How to initialize object and make accessible everywhere in project/app directory

What kind of object ? Try to explain better your context

Im using pure-python-adb library (android debug bridge), and there to start I need initialize client object: client = AdbClient(host="localhost", port="5037") So I need to initialize once and make accessible from everywhere to get devices

So you need to use client object into your views, right ?

yes, but i did initialized it in context_processors

And ? Not working ? Anyway context_processors are for templating scope You could write a Middleware to include your client object into request

Working if I need to send something in view, but if I need to get instance of the client object(for now I tried to bind client to request.sessions) it not works

Try to write a custom middleware so can include your instance into request object

Thanks

Yw 😊 Anyway for your case, if u wanna use that instance into every templates , I suggest you to work better on context_processor
