I mean, this is an update view, so maybe we already have some images associated and I want them to be graphically displayed as the new inserted ones! For this reason, we'll customize a bit the Dropzone behaviour, attaching some callbacks to its managed events. The maximum size for uploaded files is 40MB. Open your browsers console to see how RDU manages file metadata and the upload lifecycle. So I decided to split the form in two: first, the user inserts the Sale information, then after saving he can edit it and add images.Īnother thing to manage is the presence of already uploaded images. File Dropzone can attempt to parse text-based files, such as JSON, CSV, and Excel spreadsheets. You can edit code for any of these examples and see changes live. Of course, we need a Sale instance before inserting images associated to it. I created an example where I made Dropzone look and feel exactly the way jQuery File Uploader does with a few lines of configuration code. That means that images are not uploaded when the user presses a submit button transmitting also other data (the ones we need to create the Sale object). See the Theming section, for a more in depth look at how to completely change Dropzone’s UI. The problem with Dropzone is that it tries to do everything automagically and that files are uploaded by ajax. Then Dropzone does the rest, sending your file off to be saved wherever you specify. Image = models.ImageField(_("immagine"), upload_to=sale_image_file_name) Dropzone.js is an incredibly cool JavaScript library that lets you upload files immediately by dragging a file to a zone and dropping it. Sale, verbose_name="vendita", related_name="images", on_delete=models.CASCADE Title = models.CharField(_("titolo"), max_length=255) This method also triggers the removedfile event. Even though a user can drop multiple files onto the Zones, our examples use the. If you want to remove an added file from the dropzone, you can call. expandable: Allow the dropzone container to expand vertically as the number of previewed files increases. disabled: Disable any user interaction with the component. My scenario is a sort of two steps form: I have a Sale model which can have many images associated. The libraries (Dropzone javascript and css ) are in a local dist folder. Example: accept'image/jpeg,image/jpg,image/png,image/gif' maxFileSize: Set the maximum size a single file may have, in bytes. It's just a basic example, but probably a good starting point. Applies to The dropzone attribute is a Global Attribute, and can be used on any HTML element. Hi everybody, this one is just an example of how you can integrate Dropzone.js in your Django application. The dropzone attribute specifies whether the dragged data is copied, moved, or linked, when it is dropped on an element.
