Modal forms with Django+HTMX

[@adhy612000151]

Thanks Benoit! I started to learn htmx, not easy, but you explain it clearly! bravo!!!!!!

[@russf]

Excellent! Thanks Benoit. I love your style. You are very confident and you go right to the issue. I love the way you left your little mysteries in the video, and took time to solve them. Thanks again!

[@etiennecoppel9013]

J'ai galéré à mettre en place mon formulaire dans un modal et que tout fonctionne parfaitement, jusqu'à que je tombe sur ta vidéo! Une perle! Merci beaucoup pour l'aide!

[@Flechashe]

This is exactly what I was looking for, thank you so much. It gets a bit complex so thank you for explaining it in a simple and detailed manner. Great content.

[@derekkroeker4582]

I have reached 3:00 in this video so far. I will watch more soon. *Goal:* Show a Modal Form when a button was tapped, and the modal form has 3 buttons. When one of the buttons are tapped, then send the data to a queryset [ update an existing queryset ]. At last redirect to a url that are different.

[@ADPenrose]

What a great video! I actually implemented modals using django + htmx + tailwindcss this week and I'm surprised that my approach was really close to this one haha! Also, thanks for the heads up on how to listen for events. I kid you not I was just thinking about it this afternoon haha. Merci beacoup!

[@ColinVarney]

You're awesome! Literally have been looking this up for the past week on getting it implemented in a project! Thank you so much Benoit! 🙏🙏

[@BenoitBlanchon]

Thanks, Colin. It took me a while to find this pattern :-) Let me know if you have any difficulty implementing it.

[@GavinElie]

Very nice tutorial. Highly appreciated. Keep up the good work!! 👍

[@AdamMalesevic]

This tutorial is awesome! I've been looking for something like this so I could catch up with HTMX in Django. This is the perfect approach as many of us Django developers are looking for a way to integrate HTMX in our existing Django code. This could be easily renamed as a Django + HTMX tutorial as it would help people find appropriate content for starting with HTMX (in combination with Django) Thanks!

[@pau1phi11ips]

Thanks a lot. I actually needed it for PHP but it's close enough to understand how it works 😁👍

I realy like video edit at the beggining of video, explanation is great. I wonder why so few videos on your channel. I would like to see more of Python, Django and particulary HTMX Tutorials from you. Keep up the god work.

[@innerthreatcircus5651]

It would be amazing to see examples of multiple modals stacked. Natively bootstrap doesn't support it but I've seen people doing very small tweaks to make it happen. This way we could add intermediary fields and populate the previous modal with the just added record creating the only (IMO) usable experience for forms. But struggling to make this. Thanks a lot for this video anyway.

[@edup2306]

Thank you! That's exactly what I needed.

[@derekkroeker4582]

I saw at 53:00 it says *Modal from,* same thing I keep doing is using *form* when it should be *from,* and *from* when it should be *form.*

[@skumpuntele8941]

@@BenoitBlanchon Came here to ask the same question. I already have a custom middleware that will add messages to the context when using HTMX requests but only when request object is added to the returned response. It works fine when returning TemplateResponse or render() but it doesn't with HttpResponse so some kind of workaround is needed.

[@BenoitBlanchon]

You can do it without writing extra dialog.js. just use bootstrap default button event to trigger modal. Btw awesome....❤

[@rogeriodacosta5805]

Great job. I'm making a project with django+htmx+bulma based in your tutorial. I found only one problem: My modal dialogs don't keep open if found form validation errors (like unique=True field). The modal closes and the error is displayed in a partial form page with no css. Do you know how to keep the dialog open?

[@kapitankidlattv9613]

I followed to the T but the modal is not popping up, if I inspect it it's there and everything loads up :(

[@Wonganm]

Very Nice tutorial. Highly appreciated. Can the same be done using crispy forms

[@BenoitBlanchon]

I don't see any reason why this would not work with Crispy Forms.

[@forregisters2230]

Hello, the course is very good. The problem was that after applying the changes, the pagination no longer works. How can this be fixed? Very grateful, best regards.

I'm Ngoc, from Vietnam. I thank you sir. You are really great tutorials Great, very helpful. How to upload files, image file on modal- HTMX. ???? Thank you

[@BenoitBlanchon]

I didn't try but it should work as a regular Django view. As usual, don't forget to add enctype="multipart/form-data" to the form. Please refer to the official documentation for more information: docs.djangoproject.com/en/4.2/topics/http/file-uploads/

[@zongomathieu8252]

Awesome!!! But I have this error : TypeError: __init__() got an unexpected keyword argument 'headers'

Django and htmx is match made in heaven. Since I find django being too dependent to the anchor tag for triggering transactions.

[@vivaldi-qo7xj]

htmx in very useful for django. thnx for all

[@master4755]

can something like this be done without javascript

[@fullofmysteries]

Every time a new modal is opened the background goes darker and darker. Is there a way to have the same background, even after opening and closing multiple modals?

[@BenoitBlanchon]

The sample code doesn't have this problem: github.com/bblanchon/django-htmx-modal-form Ensure you're swapping the "modal" and not the "dialog".

[@peterholzer98]

Awesome. I have used this method in several projects now. Benoit, could you do the same with the HTML tag as well? I need bigger dialog form than bootstraps Modal. Or is theere any other way?

[@BenoitBlanchon]

You can use the same technique with a , you just need to call dialog.showModal() and dialog.close() in the event handlers.

[@basilhaffar3129]

when using htmx to load "movie list" instead of "{% include ...etc%}" the size is increase too much, you can see the difference if the database have 1000 records for example.

[@garidodo272]

Very nice reusable modal + htmx combo.. However, if you could make refinements such that when the user edited a movie, only the table row containing that movie will be updated, not necessarily refreshing all rows, e.g. instead of movieListChanged event in , it should be something like movieRowChanged event for . Is this possible?

[@BenoitBlanchon]

You could change this event to be "movieChanged" and include some information about the movie in the event's payload. For example, you could include the movie id or its URL so that HTMX can fetch the row from the backend; however, this requires adding a new view in Django. Alternatively, you could include all the movie information in the payload and add some JS code to update the row. However, it means that you now have two pieces of code that know how to render a movie row: one in the Django template and another in JavaScript. Honestly, this optimization isn't worth the effort: the performance improvement is marginal, but the damage to the code is significant. If your table is too big, use pagination. If pagination is not applicable for some reason, I recommend that you forget about this Django + HTMX pattern and fall back to a more classic JS Frontend + REST backend approach.

I tried using your technique with datatables but it seems unstable - sometimes the datatable will work, sometimes not.. If i build the datatable in a single page, it will work as expected.. but when i inject the partial list via the , the datatable becomes unstable. I also tried to build the complete datatable in the list.html, replaced the targeted with a in the index.html but still doesn't work.

In the select input the first option is something like "------------", that's quite annoying for me, do you know how could i change this first option to a personal message and make it hidden, selected and so?

​@@BenoitBlanchon Thanks man, now i can edit the select option text but i'm getting mad about to set some attributes like hidden, the empty_label is visible and can't figure it out how to make it hidden. Anyways, my modal form renders the entire object list inside the same modal when i click ok to create a new entry, any idea about it too? i'm going mad about that.

[@garidodo272]

I have an image field included in the modal form. In the template, I added the attribute hx-encoding="multipart/data-form" in the element. And in the view, I added request.FILES when declaring the form such that form = ProductForm(request.POST, request.FILES). However, when I tried to upload an image for the product using the modal form, and click on save, the image field has an empty value, and the image was not uploaded to the MEDIA_ROOT as defined in the settings. I got "204 No content" in the terminal/console. It works fine using the admin page. Any thoughts?

[@BenoitBlanchon]

Is it possible that you forgot to add the file field in the ModelForm? Here is a fully functional example: github.com/bblanchon/django-htmx-modal-form/tree/bootstrap4-file-upload The 204 is expected since that's the way we tell the front end to hide the modal.

Thanks for this informative video, is it possible to create an Excel-Like data entry table with htmx in Django? if possible create a video for us on that

No, I don't think it's possible to do that with HTMX. To create a data grid, you need to use a JavaScript library, like grid.js.

Benoit!, thank you very much for this great video. I have been watching it carefully for some days now. But I have a challenge. If there is an error on a popup page, where user_form.is_valid() is not valid and you return HttpResponse(status=204), how do you show the error message back to the user. If I return redirect() to a template the error messages show. Kindly help redirect me to a video that shows how to do this. Thanks.

If the form is invalid, you must render the page as usual: github.com/bblanchon/django-htmx-modal-form/blob/0c5246dc24c719dbdc07e511b807ef583eb33f68/movie_collection/views.py#L25

If using CVB, how can we add to the header the movieListChanged event? like this one in your FBV.. headers={ 'HX-Trigger': json.dumps({ "movieListChanged": None, "showMessage": f"{movie.title} edited." }) })

[@BenoitBlanchon]

I stopped using CBV years ago, so please forgive me if my answer isn't accurate. If you're deriving from FormView, you can simply override the form_valid() method and return the HttpResponse object shown in the video. If you're not using FormView, you'll have to override post() and do something similar.
