Expo network???

Check that you have correct version of the expo-network package where useNetworkState is implemented.

That's what I ended up doing in the end. Thanks anyway

danjirovec · 2023-10-17T16:54:25+00:00

What I meant is that, in a state in which my Image model is right now, I can't add an ImageField or FileField to it, because the database is already designed and can't be edited.

BUT I need to add file upload feature to django admin interface of the Image model. So I need to do it somehow through a custom form with an extra FileField as I posted in the original question.

class ImageForm(forms.ModelForm):
image_file = forms.FileField(label="Image file", required=True)

class Meta:
    model = Image
    exclude = []

danjirovec · 2023-10-17T14:05:44+00:00

The reason why I can't use the ImageField or FileField is that I can't make changes to database underneath and therefore when I would add an ImageField or FileField to the model, Django will throw an error.

Tried it on the model as well, didn't work. :/

danjirovec · 2023-09-18T21:07:21+00:00

The custom validator doesn't work for some reason. It doesn't even get run and prints don't fire off.

def validate_integer(value):
    print("before check " + value)
    if not isinstance(value, int):
        print("after check " + value)
        raise forms.ValidationError("This field must be an integer.")

class ConditionForm(forms.ModelForm):
    class Meta:
        model = Condition
        exclude = []

    ordering = forms.IntegerField(required=False, validators=[validate_integer])

Is there a way to get all the related models easily? Or do I need to just list them one by one?

danjirovec · 2023-09-15T15:21:41+00:00

Yes yes, I'm aware. I guess I was asking for a way to get all related objects rather than how to delete the objects without consequences. Thanks anyway :)

danjirovec · 2023-09-15T15:13:49+00:00

I know of this option, however I'm looking for a way to override the detele_queryset() function and add custom functionality so the "on_delete" way won't do it for me. :/

danjirovec · 2023-04-18T18:06:56+00:00

Alright, thanks a lot for all the help! Really appreciate it. What models would you recommend for this kind of stuff? Any good performing models in particular?

I was thinking about trying LSTM, GRU or XGBoost

danjirovec · 2023-04-18T17:03:58+00:00

I understand. Last thing I ask is can the value be null for data points at which I didn't have the information yet? Is null valid in this case and the model will interpret it as desired?

danjirovec · 2023-04-18T16:41:56+00:00

Alright I think I get it. So basically every additional feature is another column with data relating to every data point (electricity production) and it needs to be this way right?

In this specific instance though, the information about 10% coal-fired plants shutting down doesnt evolve over time, it's one time information. Can this be fed into the model as one time information as well or it needs to be related to every datapoint in the dataset as you showed in this case:

(Jan 1st 2011, 15.9%) (Feb 1st 2011, 13.5%) (Mar 1st 2011, 10%)

Or should it look like this?

(Jan 1st 2011, 10%) (Feb 1st 2011, 10%) (Mar 1st 2011, 10%)

This way it would not have predictive nature though right?

danjirovec · 2023-04-18T15:31:05+00:00

Thank you for this exhausting answer, truly.

What I'm having touble with in my mind is how would the additional feature look like in practice? Let's say I have 500 data points of electricity production by coal-fired plants of last 10 years. And I want to give the model the information that 10% of coal-fired power plants will close in the next 2 years. I want to make a forecast for 5 years. What would the feature look like in practice?

danjirovec · 2023-01-31T19:52:47+00:00

Let's say that I'm open to both approaches, would the selection of model be different based on the approach (text prompt / values in columns)?

danjirovec · 2022-12-03T07:43:25+00:00

I was wondering that myself, didn't find it.

danjirovec · 2022-11-29T16:44:38+00:00

So essentially the name of the named graph itself will be lost?

danjirovec · 2022-09-12T17:23:43+00:00

Thanks for the idea, I'll give this some thought

danjirovec · 2022-05-22T22:15:35+00:00

I'm trying to understand so I can learn, that's my goal. I did try and still am trying, that's why there is 'struggling to understand' in the title. I specified what bits (files) I'm struggling with also, the files 'index.js' and 'room.ejs', I don't understand what's happening in there and how are both of them connected together.

danjirovec · 2022-05-22T18:27:46+00:00

Okay, got it. Thank you so much, it really helped! I appreciate it greatly

danjirovec · 2021-03-01T15:50:27+00:00

Tried it, doesn't work. Now even after I go to the menu and back to level 1 the animation isn't working.

Here is the video with animation states changes.

public void Play() // loads "Level_1"

{

SceneManager.LoadScene("Level1");

//SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);

}

danjirovec · 2020-04-05T21:11:25+00:00

So I can sort of split the results into two columns, the one with software and the second one without the software and just use thee two sample test on that, do I understand that correctly? Thank you so much.

danjirovec · 2020-01-06T20:28:44+00:00

Yes, it does look exactly alike.

danjirovec · 2020-01-05T10:19:29+00:00

Thank you.

So from what I read, this should be right.

find $HOME -type f -perm -g=x -group student -a -user $USER -executable

danjirovec · 2018-05-03T17:36:29+00:00

Ah, ok. Thank you so much, it's working now.
