I am trying to let my users upload multiple pictures to their blog posts. I have created a model for the blog post and a separate model for the images and used a foreign key to relate them. I was planning on using dropzone.js so that the user can drag and drop the pictures. I have looked into using formsets but can't get my head around them. Can anyone explain to a django beginner how to go about doing this? Or better yet give an example? Thanks!
I have done something similar using jquery-fileupload. Never used dropzone.js so maybe the explanation is not directly equivalent, but this is roughly what you do.
If you don't want to use formsets, upload the images via AJAX and add hidden fields to the form with the primary keys of the uploaded images, so you can attach them when saving the blogpost in Django. You will have to deal with orphaned images (those that were uploaded but the blogpost was never saved.)
If you want to use formsets, Django expects a format in the posted form data, you just need to make sure you create in your html (with dropzone js templating) the apropriate format Django is expecting, and also incrementing/decrementing the counter of the formset's management form.
Neither way is trivial, you need to pick a path and bang your head a few times before having it working.

I have been struggling trying to create Post model which allows user to upload multiple images. Assuming that every publication is a row in post model, I guess, we should store images for each publication in single table cell in its row (sorry for redundancy, I just want to make sure that nobody gets me wrong). Is it possible and is it a right way to do this?
Also, maybe I should make N image fields in model and make it look for user like he fills one form field in frontend and at that time images are being put into other hidden image fields?
Sorry, if I am being dumb, I am new to django. I appreciate any advice!
New to Django here. I have a link to a form in DJango. I use the CreateView to have the user enter the initial information. It all works great and the data is accurately saved to the database. My issue is this: I would like that same link to open the form (it's a one-to-one relationship) with the filled data so the user can see what they have previously entered and correct, edit or update as needed. The form currfently opens as a blank form so if the user has entered that information previously they are unable to see it. I cave researched get_or_create and update_or_create as well as a number of other topics, but can't seem to figure this out. This needs to be a user-friendly experience so multiple entires or clicking multiple buttons to access the data is not an option. How best can I implement this?
#Don you can checkout django formsets, I think this will help in this situation. And you can use a single FormView for all your needs by overriding its methods.
Have you looked at Django Sessions. It’s a simple way of saving session data and passing the data to future requests. https://docs.djangoproject.com/en/3.0/topics/http/sessions/. I. In your form view you cloud save the session data you want to pass to your next form. In your next form, you could use the session data as default values. I’ve done something similar in the past.
I have coworkers to upload posts through Django admin. The problem is they keep making duplicate posts as we've been covering a lot of posts. Is there a way to find out if a post already exists when typing a certain column or submitting?
I searched about that, but didn't get any useful information.
Your business case seems to be a text that is duplicate if it is case sensitive equal.
On a DB and Django Model level you assure unique entries by adding unique:
class MyModel(Model):
my_field = TextField(unique=True)
To check during input you need JavaScript in the client and an AJAX endpoint on the Django server side. It's actually an Autocomplete/Autosuggest functionality for that field. There are several packages that might help you with that. Out of the box, the Django Admin does not support this.
I have a website that is using Django's admin interface to facilitate non-developers adding content to the site. The site has an Events page (and associated model), and each Event can have an associated photo gallery.
I'm thinking that photo galleries should have their own model. There is a table in the database which associates image paths with their Event.
What I need is a way to upload images. Preferably a multiple-file upload solution since there could be dozens of images per event. I want these images to be recorded correctly in their table and added to the file system in the correct location on the server.
I was originally thinking that the upload feature should be included on the Event admin page to make it easier for content contributors, but maybe it would be easier to keep a separate photo gallery admin and have them select the Event the photos are associated with from there?
I've read through a lot of similar questions and blog posts, but nothing that seems to be quite exactly what I'm looking for. I'm currently attempting to adapt some of the information I've seen, but I'd really appreciate suggestions. Thanks for any help on this!
You can create Some model with foreign key to Event, and ManyToMany to your Images, as I understand your question.
At first upload necessary images to some Image model and than add them to Some model with some Event
I've got several forms in my django app that require support for attachments. Each form instance may have any number of attachments, including none. I want to present a jQuery based upload widget for managing these uploads, allowing the uploads to be processed asynchronously. The attachments are stored in their own model, so there is then a many-to-many from the attachments model to each model that requires attachments. When an attachment is sucessfully uploaded and processed, the view handling the upload will return the id in the attachments model, which will then be inserted into a hidden field on the form. I'm currently trying to decide how best to represent this in the form.
One method would be to simply have a single hidden input which takes a comma separated list of ids. This would then require quite a lot of manual processing and validation on submission, which I can't help feeling could be avoided.
Elsewhere, I've used a HiddenInput for a single value where I'm doing something similar and dynamically adding items to the related model in the form. I can't however see how I can extend this directly to a Many to Many from a simple Foreign Key.
Anyone able to suggest the best way to go about doing this?
Try to use formsets or model_formsets to create a form for creating/editing multiple objects, also you can use javascript to add forms dynamically in your browser.
