Django Form Disabled Select Option Values Not Submitted Even When They are Enabled with JavaScript Before Submission
My HTML displays about 20 or more forms via modelformset_factory and each having a preselected staff name (so this is disabled in forms.py). Staff name is primary key to Staff model, so I don't want all their names be available for selection. Logged in user have some staff assigned and so they are only required to enter phone number and address. The disabled fields are enabled with Javascript before the form is submitted but I still get {'staff_name': ['This field is required.']} error when the form is submitted. Here are my codes: forms.py class StaffForm(ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['staff_name'].disabled = True views.py class StaffModelFormSet(BaseModelFormSet): def clean(self): super().clean() print(self.errors) class StaffEntryView(LoginRequiredMixin, FormView): def post(self, request, *args, **kwargs): StaffFormSet = modelformset_factory(Staff, form=StaffForm, formset=StaffModelFormSet) submitted_form = StaffFormSet(request.POST) if submitted_form.is_valid(): self.form_valid(submitted_form) print("This form is valid, Sir!") else: self.form_invalid(submitted_form) print("This is not a valid form.") template.html <form method="post" class="form-control" id="staff_form" name="staff-form" onsubmit="enablePath();"> <!-- form details goes here --> <tbody> {% for form in formset %} <tr class="table-striped"> <td>{{ form.staff_name }}</td> <td>{{ form.phone }}</td> <td>{{ form.address }}</td> </tr> {% endfor %} </tbody> script.js function enablePath(e) { var options = document.getElementsByTagName('select'); for (var i=0, iLen=options.length; i<iLen; i++) { options[i].disabled = false; } -

which architecture is good for my mobile Chat app in this situation?
I am developing an android app connecting to django backend. My django server in AWS already has own mysql database. (firebase is used for sns authentication) Now I have to add chat functions to this app. It includes group chatting but probably many users may use 1:1 chatting. My question is which architecture is good for mobile Chat app? Options I am thinking now .. Chat messages are stored in mysql database in AWS, and server notify message by only using FCM(Firebase cloud messaging). All text, image or voice urls would be in payload for FCM. A user can only log in on one device at a time. (If this option has no critical performance issue, I think it is a simple way, because I already have backend with database, and I don’t need to care whether user’s Mobile App is in foreground or background. If App needs to show messages when chatting room(channel) is mounted on screed, otherwise just uses notification tray) Use Firebase Realtime database only for chatting functions. It is real time, but I need to create an additional DB in Firebase, and I am not sure how to handle message when app is in background. Chat … -
Put multiple divs on same line using CSS
I'm currently working with Django, and i'm doing a view, where multiple objects from a list are displayed. Right now, each of those objects is on an own line. But i want to have e.g. 2 on one line, so the list is less long on the page. This is my Code so far: html: {% for plant in plants %} <div class="plant"> <img src="{{plant.icon}}"> <div> <label>{{plant.common_name}}</label> <input type="number" name="percentage"/> </div> </div> {% endfor %} CSS: .plant_beet_form { width: 100%; margin: 0 auto; font-size: 3rem; } .plant div { width: 70%; margin: 0 auto; } .plant input{ margin: 0 auto; width: 100%; font-size: 2.5rem; } .plant img { width: 10rem; height: 10rem; margin-bottom: 1rem; } .plant { width: 30%; margin: 0 auto; margin-bottom: 2rem; } I already tried using display:grid and grid-template-rows: 1fr 1fr, but this didn't work either. Any idea? Thank you -

Table Buttons to Submit Changelist Form in Django
I currently have the following admin page with a set list_editable fields in my ActivityLogAdmin model. When I click "Save" on the bottom of the admin page, the request.POST data gets submitted to my form. I have the following method under my ActivityLogAdmin class: def get_changelist_form(self, request, **kwargs): return ActivityLogChangeListForm However, I'm trying to add one custom button for each entry in my change list, so when I click it, the POST data should also be passed to a view so I can handle that data. However, I can't seem to pass this request.POST data of when I click the button to the view.
