'chromedriver' executable needs to be in PATH in Python Django
I am trying to execute a Python script in Django.

Ordering models using Django AutoField with custom step size
Consider a model Section that is displayed on a site and created / edited by a user using the Django admin interface. I would like to add a field that allows the user to easily control the order in which sections are displayed on the site. The easiest option seems to be to allow for an integer field that is auto-incremented but can be edited by the user -- akin to what the built-in AutoField does. However, to make editing the order easier, I would like to increment the fields default value by 10 every time, to allow the user to shift sections around more easily. The first section would get order=1, the next one order=11 and so on, that way a section can be wedged in between those first two by giving it, e.g., order=6. Is there a way I can reuse AutoField to achieve this purpose? And if no, how could I best achieve this type of ordering scheme? -

Is there a way to duplicate entire data from one project to the other in Django?
So I've made and been running a beta test of my project for a couple of months. It is a CRUD application, where user posts some stuff. The thing is, I realized that I might have to pivot the item a little, so I'm planning to build a new project from the beginning. But the posts of my beta testers have to be kept as-is, so I want to migrate(or duplicate) the entire data to this new project. Given that I have the exact same model as the original project in the new one, is there a way to make this possible? Or (I strongly hope not, but) do I have to manually copy+paste all the data? The posts are quite private so the users wouldn't want me to copy+paste them. Thank you very much in advance. :) FYI, I'm using AWS EC2 and Postgres. -
How to override Django file input in forms.py?
I want to override the default input looking, I'm not looking to change an attribute, I'm searching for something more advance So here is a normal Django input file field with crispy_tag_forms <div id="div_id_image" class="form-group"> <label for="id_image">Image*</label> <div> Currently: <a href="/media/profile_images/DefaultUserImage.jpg">profile_images/DefaultUserImage.jpg</a><br> Change: <input type="file" name="image" accept="image/*" id="id_image"> </div </div> However this looks very ugly, so all of the time I completly hide it and write my own that looks something like this <div style="display:none"> ... <input type="file" id="id_image"> ... </div> <p class="btn btn-outline-success" onclick = "document.querySelector('#id_image').click()" onchange = "this.innerHTML = document.querySelector('#id_image')[0].files[0].name"> <i class="someicon"> Image </p> And to be able to do so I have to use some Javascript, however for some reason, it always puts it at the end of the form which is not what I want, and I won't be writing the same function over and over again for each form I create with Django Is there any way to make this the default django file field? -
Assign permissions to users in Django groups
I'm using Django (3) with a custom user model using BaseAbstractUser in which I have a BooleanField field named is_instructor and also created a group named instructor. So when the user signup with is_instructor he will have all the permissions of the instructor group. And to this group I assigned all the permissions related to my courses app in Django admin.

Django not rendering python variable in template
I have a string variable in a Python file that I am trying to render in my HTML template. The variable is called contacts, and in my template, I have {{contacts|default:"null"}}. From the documentation, it seems like that should work, but the template keeps coming up with the null keyword. I've scoured the documentation and found nothing. Probably a super simple thing I'm overlooking that has frustrated me to no end. In the python file, I'm using an API to get a JSON and unloading it into a dictionary (don't know all the specific terms), where I then extract the value I need into a string: ... dict_data = dict(json.loads(data)) contacts = str(dict_data["contact_count"]) Then in my HTML file: <p class="spotbanner"> {{contacts|default:"null"}} spots left! </p> Is there something else I'm missing? Something super simple that I just don't understand about Django despite having used this method before? Happy to provide more information. -
