Got a trouble with ManyToMany field in DialogModelForm

[amikphoto]

Is it possible to use SelectizeMultiple in DialogModelForm?
In my Formset I have

DishSet = DishSet()

(class DishSet(FormCollection):
dish_form = DishForm()
dish_images = DishImageCollection())

And All these forms below are DialogModelForms
add_cat_form = AddDishCatalogForm(is_modal=True)
edit_cat_form = EditDishCatalogForm(is_modal=True)
edit_class_form = EditCulinaryClassForm(is_modal=True)
add_class_form = AddCulinaryClassForm(is_modal=True)
edit_type_form = EditTypeForm(is_modal=True)
add_type_form = AddTypeForm(is_modal=True)
add_dish = AddDishLibraryForm(is_modal=True)
edit_dish = ChangeDishLibraryForm(is_modal=True)

All DialogModelForms are for add/edit elements from fields of DishForm.
Everyrhing worked fine with ForeignKey relations. But I decided to use ManyToMany relation for one field. And It seems to me it doesn't work. Could you just let me know is it possible to use SelectizeMultiple in DialogModelForm?

I never tested this, but I will try so soon.

What exactly do you mean with "it doesn't work"? The widget itself, or doesn't the database accept the values?

It doesn't show selected values when I open form to edit. And I've got "Select a valid choice. That choice is not one of the available choices." in form when I submit ModelDialogForm

Since naming is hard, please make my life easier by describing your use-case so that I can recycle your names in another example below testapp.

I have a main collection of forms in which I enter data on the quality of a dish in a cafe (I select the dish itself from the foreignkey guide and add a description and rating).
If there are no dishes in the directory, I add them using the button in the form. (or edit the currently selected dish)
To enter a new one or edit it, I use the Dialog ModelForm. In this form, I open all the fields of the food directory, which, in turn, are also ForeignKeys to the directories.
And here I would like to be able to add not one value for a field, but several.

I hope it became a little clearer.

[amikphoto]

I hope it's clear.
Do you need more explanations?

Maybe I'm wrong, but I have a feeling that if the form with SelectizeMultiple in formcollection then problems arise, in particular, the form for editing does not open. The same form opens and works fine if it is not included in formcollection.

[amikphoto]

I've made some tests... and I can add that... SelectizeMultiple works fine in formcollections but problem is started when I add DialogModelForm to collection. I've got an error in C:\myprojects\critifood\env\Lib\site-packages\formset\templates\formset\default\field_group.html (ValueError at /test/1/
Field 'id' expected a number but got 'Тест'.) Тест - It's the name of dish in my table.

[amikphoto]

I'm so sorry.... It seems to me I'm an idiot. Thank you very much for your project and... again... I'm sorry
Everything works fine...

[amikphoto]

but anycase I would love to ask you to make working example in testapp with ModelDialogForm and ManyToMany field in it.

[jrief]

Anyway, I'm always interested in small examples to add as demo to the testapp project. I'm currently working on other stuff, so feel free to add this yourself.

[amikphoto]

Thank you...

I have some new questions. I have achieved the functioning of my forms with DialogModalForm only with your great formset, but still I got a few problem. When using ManyToMany fields, it is not clear how to fill them in when
action='submit Partial -> setFieldValue(edit_dish.CulinaryClassModel_fk, ^CulinaryClassModel_fk_id) -> activate("clear")'

It that case I can set only one value not many.

[jrief]

Maybe this is not implemented yet. Give me some time to have a look.

I have discovered one of the problems... The fact is that in my formset, using DialogModelForm, I'm trying to save a value in a table and set this value using setFieldValue. But the fact is that the value being set is represented as a manytomany field. Accordingly, as I understand it, the django script is a formset.js does not perform setFieldValue properly. I would like to be able to add new values to the table and then substitute the new value in the SelectizeMultiple widget (for example, by deleting all previous selected items or substituting it first or last).
Is this approach generally correct?

[amikphoto]

Waiting for your working exmple with manytomany in DialogModelForm. In my case everything work but when I open DialogModelForm with manytomany selectize widget for editing it doesn't refresh values after save partial.

[jrief]

This has been fixed in the latest commit on branch releases/2.0.
This was indeed a bug. It now works with the SelectizeMultiple and DualSelector widgets. It can't work with the native <select multiple> HTML element.

I have added an example to the demo apps, please check http://localhost:8000/bootstrap/issue-many

Thanks for reporting and please share your feedback!

I updated testapp and tried issue-many. After I press Create Reporter the DialogModelForm doesn't clear. But new reporter name was saved to database and I could find the name from selectize widget in Reporters field. It works but not complete.

[amikphoto]

I was wrong and it works. Thank you. I just didn't set up new JS correctly. That's why I got unworking version of issue-many. While building JS I've got: client/django-formset/RichtextArea.ts:36:20:
36 │ import {parse} from '../build/no-comments';
╵ ~~~~~~~~~~~~~~~~~~~~~~
And It has worked after I commented this.

[jrief]

And It has worked after I commented this.

Don't do that.
I forgot to fix the docs, there it should state:

npm run no-comments

this build the parser you couldn't import.
Sorry, my bad.

[amikphoto]

Yes, everything works fine! Is it possible to add ability to edit many_to_many options (for example, if I have only one choise the button "edit" is active and I can edit this option. It works now but after you click save, the result is not set in the many to many field.
