Naming convention for Django migrations
Is there a best practice naming convention for Django migrations? If it's a small migration the names are pretty obvious, but things get harry when multiple fields are being changed. Just wondering if anyone has a standard they like to use. -
Django - error from call to values_list: 'flat' is not defined
Here's a loop I'm using to process an Excel sheet with openpyxl. On occasion the partno field is missing and I try to derive it from another database table (booking) using a field called transmittal. I'm having trouble with this lookup and it returns an error. When I run the same thing under the Django shell, it works fine. parser = parse_defrev(book) brs = [] xmtl_part = {} invalid = [] for r in parser.process(): # If no partno, try to look it up in the bookings table if r.get('partno') is None: xmtl = r.get('transmittal') if xmtl: r['partno'] = xmtl_part.get(xmtl) if not r['partno']: parts = set(Booking.objects.filter(bookingtransmittal=r['transmittal']).values_list('bookingpartno', flat=True)) if len(parts) == 1: r['partno'] = parts.pop() xmtl_part[xmtl] = r['partno'] process is a generator function in the parse_defrev class which returns a dictionary with the processed fields from the workbook. If partno is missing, then it first tries to retrieve it from a caching dictionary and then from the booking table. The values_list returns any matching partno values, and if there is more than 1 match it just logs the problem and skips to the next row. I get the following error, and don't understand how it could fail to recognize the flat … -
How to run migration against a different database in Django?
I'm using two database instances in Django, one is in Postgis and the other is in Postgres itself. Postgis is a geospatial database that has some model fields and features that the PostgreSQL database which is its extender does not have. When I run the ./manage.py migrate, to avoid tracebacks, I want the migrations related to Postgis migrate to Postgis and the ones related to Postgres migrated to Postgres which is the default database. I could do this by specifying --database="postgis" while running the migration command but it would be best option to avoid doing that. -
ERR_CONNECTION_TIMED_OUT when trying to access AWS EC2 hosted Django application
I'm stuck with ERR_CONNECTION_TIMED_OUT in browser when trying to access Django application which is deployed to AWS EC2.

Django RestAPI, expose a function instead a model
In my django project i have a function like thisone: def calc_q(start_d, end_d, var_id): d = {"[": "", "]": "", ",": ""} var_results = VarsResults.objects.filter( id_res__read_date__range=(start_d, end_d), var_id_id=var_id, var_id__is_quarterly=False ).select_related( "id_res", "var_id" ).values( "id_res__read_date", "id_res__unit_id", "id_res__device_id", "id_res__proj_code", "var_val", "var_val_conv" ) df = pd.DataFrame(list(var_results)) df['id_res__read_date'] = pd.to_datetime(df['id_res__read_date']) df = df.set_index('id_res__read_date') df_15 = df.resample('15min')['var_val_conv'].agg(['first','last']) return pickle.dumps(df_15) well, function used instead of my project works well but i need to expose this function as an API for leave external user to call it specifying parameters (dates and var_id) and get pandas dataframe serialization results. How can i expose this function using Django Rest APi, i read something about serializers.SerializerMethodField but i don't understand how exactly it works and if it could be useful for my intention. So many thanks in advance Manuel -
Django's django-crispy-forms not showing asterisk for required field on form
As the title states I have a required field displayed on a form, and it doesn't show the asterisk to indicate that it is required. NOTE: The field is not required on the models side, but I set it on the forms.py side. models.py: class ErrorEvent(models.Model): """Error Event Submissions""" event_id = models.BigAutoField(primary_key=True) team = models.CharField(verbose_name="Team", blank=True, max_length=100, choices=teams_choices) event_name = models.CharField(verbose_name="Event Name", max_length=100) forms.py: from django import forms from .models import ErrorEvent class ErrorEventForm(forms.ModelForm): class Meta: model = ErrorEvent # fields = exclude = ['event_id'] widgets = { 'team': forms.Select(attrs={'required': True}),} When I check the website 'Team' is shown to be not required (but you can't finish the form without filling it) However 'Event Name' is shown to be required. Anyway I can fix this? Thank you for all help in advance! -
DJANGO MultiValueDictKeyError problem with UPDATE
I had a working update table. I am updating in the same form. But after entering the photo upload codes, the problem of updating other variables appeared.

Simple tag loosing the value set after leaving a FOR tag in template
I have this simple tag defined and loaded into my template: from django import template @register.simple_tag def defining(val=None): return val The tag works! My goal is, i want to set a value for a variable using this simple tag inside the FOR looping using some condition, and then, check the value of this variable after leaving the FOR. Simple right? {% defining 'negative' as var %} {% for anything in some_query_set %} {% if 1 == 1 %} {% defining 'positive' as var %} {% endif %} {% endfor %} <p>The value of var is: {{var}}</p> The problem is: I want this variable 'var' to be 'positive' after leaving the for, but it always turn into 'negative'. I've checked its values inside the IF and inside the FOR and it gets 'positive' as expected, but after leaving the FOR, it gets back to 'negative'. I may have some workaround using context variables through views, but i really need to do this in the template. I also searched the forum, but i couldn't find anything close enough to explain me why this is happening. Am i missing something? I'm kinda new to Django, so i'm trying to avoid more complex aproaches, … -
Passing a variable to an included html modal with Django
I wanted to quickly build a small web app, so I decided to go purely with django and what django offers - template rendering, so no React/Vue or such. The problem that I am having is, that I have some cards, which are being displayed in a for loop (jinja) once the user clicks on a card, a modal shows up and this is where it gets messy. I want to pass the id of the card, so that I can make a get request and render the data in the modal. The code that I have is: // index.html <div id="machine-cards" class="grid grid-cols-3 gap-4 m-20"> {% for machine in machines %} <div id="card" class="bg-white shadow-md rounded px-8 pt-6 pb-2 mb-4 transform hover:scale-105 cursor-pointer"> <div id="card-header" class="flex justify-between"> <p>Machine number: {{ machine.number }}</p> <div id="state" class="rounded-full h-4 w-4 {% if machine.status == 1 %} bg-green-500 {% elif machine.status == 2 %} bg-red-500 {% elif machine.status == 3 %} bg-yellow-500 {% else %} bg-gray-500 {% endif %}"> </div> </div> <div id="card-body" class="flex justify-center align-center mt-5 mb-5"> <p>{{ machine.manufacturer }}</p> </div> <div id="card-footer" class="flex justify-end"> <p class="text-gray-300 text-sm">Last updated: 28.06.2021</p> </div> </div> {% endfor %} </div> {% include "general/modal.html" %} <script> function … -

Having trouble running the django extensions command reset_db programatically
Basically I am writing a script to reset a django webapp completely. In this script, I want to reset the database, and there is a command to do it from django extensions. Unfortunately, I haven't been able to run it programatically. It works fine when I run it via command line, but it just won't execute when I try programatically. I have tried using os.system and subprocess. I have also tried using management.call_command('reset_db'), but it keeps saying that there isn't a command called reset_db. I have checked to make sure the django_extensions is in my installed apps, so I have no idea why that isn't working. Does anyone know how I could fix this? Thank you! Also I am using python3, the most recent version of django I believe, and it is a MYSQL server that I am trying to delete. -

Overwrite validate_unique with M2M relations
I am trying to implement my own validation for a many-to-many relation (m2m) since django does not allow m2m fields in the unique-together constraint (https://code.djangoproject.com/ticket/702) (Django Unique Together (with foreign keys)) What I want is to check is if a newly created object instance is already existent within the scope of a m2m related model. Imagine I have the following 3 models: class Juice(model.Model) name=CharField, year=IntegerField, flavor=CharField class Company(model.Model) name=CharField, cooperates=ManytoManyField juice=ManytoManyFiedl class Cooperate(model.Model) name=CharField That means that a company can have many juices and many juices can belong to many companies. Equally a company can belong to many cooperates and a cooperate can belong to many companies. What I want to implement now is the following restriction: Whenever I create a new juice with name, year and flavor it should validate if a juice like this already exists within the scope of the Cooperate model. That means if there is any company within the cooperates that already have this juice it should raise a ValidationError. Let's say for example I create a new juice (bb-sparkle, 2020, blueberry) it should raise a validation if cooperate-optimusprime already has a company (e.g. company-truck-juices) that has a juice with bb-sparkle, 2020, blueberry.

How to implement Django multiple user types, while one user can have different role according to the project he/she is working on?
I couldn't find a solution to my problem and would appreciate comments/help on this. I would like to develop a multiple user type model in Django, along the lines of this video where the author is using Django Proxy Models. Situation I have a list of XX projects (proj01, proj02 , projXX, ...). All these projects have their specific page that can be accessed through a specific url mysite/projXX/ I have multiple users: Adam, Bob, Caroline, Dany, Ed, ... Each user can have several roles according to the project they are working on (e.g. manager, developer, documentarist, reviewer, editor, ...) A user can have a different role according to the project. E.g. Adam can be reviewer on proj01 but editor on proj02 while Bob can be editor on proj01 but reviewer on proj02, etc..

CircleCI Exit Code 137 after upgrading Docker-Compose Container of MySQL from 5.7 to 8.0.2
Good day, everyone. Hope you're doing well. I've been stuck with this for quite a while now. I'm not really sure what can I do to Debug, because I'm a newbie in CircleCI. What I've done is that I've narrowed down an Exit Code 137 from CircleCI to a change in the version of MySQL container in Docker Compose. That error is usually related to OOM, but I've already bumped up the memory of CircleCI to 8GB with resource_class: large and the error keeps happening. Let me be clear this is NOT happening locally.
